Description
Technical Field
The application relates to the technical field of rust preventive oil, and mainly relates to stamping electrostatic spraying rust preventive oil and a preparation method thereof.
Background
The rust-proof oil is mainly used for preventing metal products and products taking metal as a main material from being rusted, and the electrostatic spraying rust-proof oil is used on an electrostatic oiling machine, and is suitable for electrostatic oiling rust prevention of various coating plates such as cold-rolled sheets, galvanized sheets, aluminized zinc sheets and the like in the metallurgical industry.
The anti-rust oil for electrostatic spraying has higher requirements on anti-rust property, for example, after the strip steel is coated with oil and packaged, the anti-rust oil is generally required to have an anti-rust period of storage and transportation of half a year to one year. Meanwhile, in view of the special use process, namely high-voltage electrostatic spraying, special requirements on breakdown voltage, atomization performance, smell and the like of oil products are met: the breakdown voltage is generally required to be higher than 35KV to meet the use safety of high-voltage electrostatic spraying; the oil product is required to have excellent atomization performance, so that the electrostatic spraying rust-preventive oil can be atomized (form charged small oil drops) in a high-voltage electrostatic field, and then the electrostatic spraying rust-preventive oil is directionally adsorbed on the surface of the travelling strip steel, so that uniform coating of the electrostatic spraying rust-preventive oil is realized; the rust preventive oil is required to have no peculiar smell, and the peculiar smell of the oil product can be fully released in the atomization process because of atomization spraying, so that the environment of an operation space is affected.
Along with the optimization of downstream processing procedures of cold-rolled/coated strip steel and the improvement of the use requirements of clients, the electrostatic spraying antirust oil also has more performance requirements: (1) The processing process of downstream customers of the strip steel mainly comprises stamping forming, and the finished products are home appliance shells, furniture components and the like. In the stamping process of the strip steel, special stamping oil needs to be coated so as to meet the lubrication requirement in the processing process and avoid the defects of scratches, burrs and the like on the surface of the strip steel. For some working conditions (components with small deformation) with low stamping performance requirements, downstream customers can want to provide lubricity through the rust preventive oil coated in the previous working procedure, so that the cost of oil is saved, the processing working procedures (the working procedures of cleaning the rust preventive oil and coating the stamping oil) are reduced, and the production efficiency is improved. Thus, the electrostatic spraying rust preventive oil is required to have a certain lubricity while meeting the rust preventive requirement. (2) The electrostatic spraying rust-proof oil is coated on the surface of the strip steel to meet the requirements of rust prevention, lubrication and the like of the strip steel in the processes of storage, transportation and stamping. In the subsequent processing and using process of the strip steel, the coated rust-preventive oil needs to be cleaned to ensure the cleanliness of the surface of the strip steel. The cleaning process is generally to soak or spray the strip steel with alkaline cleaning agent, and the grease on the surface of the strip steel is cleaned by saponification reaction of alkaline substances and rust-proof oil. From the requirement on the performance of oil products, the electrostatic spraying rust-preventive oil also has the characteristics of easy cleaning and less residue. In the prior art, the lubricating property and the rust resistance of the rust-preventive oil are enhanced by adopting a mode of improving the viscosity of the rust-preventive oil, but the washability of the rust-preventive oil is often reduced due to the high viscosity. (3) The electrostatic spraying rust-proof oil is named because of the special use process, and the oil is atomized into uniform oil drops in a high-voltage electrostatic field, so that the oil is directionally adsorbed on the surface of a workpiece, and the atomization performance of the oil directly influences the coating uniformity. With the improvement of various properties such as lubricity, cleaning property and the like of electrostatic spraying antirust oil, the atomization performance of the electrostatic spraying antirust oil needs to be optimized.
At present, researches on electrostatic spraying rust preventive oil are carried out, and the environmental protection (China patent application CN 108865362A and China patent application CN 103911206B) and the multifunctionality (China patent application CN113088367A and China patent application CN 112646641A) of the concentrated rust preventive oil are carried out. The Chinese patent application CN115305133A relates to the related research work of lubrication type electrostatic spraying rust preventive oil, and the scheme realizes the lubricity of the electrostatic spraying rust preventive oil by supplementing ester components such as oleate, palmitate and the like on the basis of the formula of the conventional electrostatic spraying rust preventive oil. However, the research of the scheme aims at meeting the use requirements that a lubricant is required to be applied during cold rolling and rust-preventive oil is required to be sprayed after annealing of the steel plate, and the cold rolling lubrication and rust prevention integration is realized. The scheme can not meet the stamping lubrication requirement of the oiled strip steel in the downstream working procedure, and is not designed and tested according to the special stamping lubrication process.
The stamping lubricating rust preventive oil for the plate stamping process has more research results. The common lubricant components such as polymeric ester, sulfur-containing extreme pressure agent, phosphorus-containing extreme pressure agent and the like are mostly adopted to improve the stamping lubricity of oil products. On one hand, the special stamping lubricating oil has higher lubricating performance requirement and is suitable for stamping processes with large deformation; the electrostatic spraying rust preventive oil is used as a lubricating medium, is limited to a stamping process with small deformation, and is not suitable for the electrostatic spraying rust preventive oil because lubricating components are selected according to lubricating requirements and sulfur-containing lubricating agents often have obvious peculiar smell; on the other hand, the existing research of stamping rust preventive oil does not consider indexes such as atomization performance, cleaning performance and safety of the oil, and a formula system is not suitable for electrostatic spraying of the rust preventive oil; finally, in the existing research schemes of stamping rust preventive oil, the PB and PD values obtained through four-ball friction test are used for representing the lubricity of the oil, but the PB and PD values are used for evaluating the lubricity of the oil through point contact between steel balls and friction pairs rotating at high speed, which is inconsistent with the low-speed and low-frequency process characteristics of the plate stamping process, and the stamping process cannot be well simulated.
Accordingly, the prior art is still in need of improvement and development.

Detailed Description
The application provides a stamping electrostatic spraying rust preventive oil and a preparation method thereof, and the purpose, the technical scheme and the effect of the stamping electrostatic spraying rust preventive oil are clearer and more definite, and the stamping electrostatic spraying rust preventive oil is further described in detail below. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The electrostatic spraying rust preventive oil is widely applied in metallurgical and mechanical processing industries, realizes uniform atomization through an externally applied high-voltage electrostatic field, and is then directionally adsorbed on the surface of strip steel. By quantitative oil feeding and atomization spraying, quantitative and uniform oiling can be realized. After the cold-rolled/galvanized strip steel is oiled, the coated rust-proof oil can be used as a lubricating medium in the next process of stamping forming. After the stamping forming, the rust preventive oil on the surface of the workpiece needs to be cleaned in order to ensure the cleaning of the surface, so that the cleaning performance of the rust preventive oil is also required to be high.
In the scheme, the formula of the existing electrostatic spraying rust preventive oil is designed and optimized, so that the high-cleaning stamping electrostatic spraying rust preventive oil is developed, has excellent rust preventive property, coating property and the like, and simultaneously has outstanding lubricity and cleaning property, so that the stamping electrostatic spraying rust preventive oil is more suitable for online spraying rust prevention of cold-rolled/coated strip steel. The lubricant is optimized by combining the stamping process and the lubrication requirement of the oiled strip steel, and the phosphorus-containing lubricant and the high-base number calcium sulfonate compound are preferably used as the main lubricant of the system. Under the condition of meeting the lubricating requirement, the scheme of the surfactant is optimized, so that on one hand, the surface tension of the oil product is reduced, and the atomization performance of the oil product is better; meanwhile, the cleaning performance of the stamping electrostatic spraying rust preventive oil is improved. In addition, in the scheme, the lubricating scheme is tested by adopting a test method of a low-frequency motion and point-line contact friction pair in combination with the process characteristics and the lubricating requirement of a plate stamping process, the stamping process is better simulated, and the lubricating scheme is selected by combining the test result of a four-ball friction and wear tester, so that the lubricating property of an oil product is better evaluated.
The stamping electrostatic spraying rust preventive oil provided by the application is moderate in viscosity, high in lubricating performance, free of pungent smell and high in cleaning performance, and can be applied to stamping processing. Specifically, the stamping electrostatic spraying rust preventive oil comprises the following components in percentage by mass:
75-88.9% of base oil, 10-20% of rust inhibitor, 0.5-5% of lubricant, 0.5-2% of surfactant and 0.1-2% of antioxidant.
Regarding the base oil, for a general electrostatic spraying rust preventive oil, the kinematic viscosity thereof is 10-30mm 2 Between/s, it is therefore generally considered to choose an kinematic viscosity of between 10 and 35mm 2 Oil products per second are used as base oils. In the present application, the base oil is optimized, and the base oil is 150N paraffin base and 60N paraffin base according to the following formula 1: (4.5-6.0), wherein the saturated hydrocarbon content of the base oil is more than or equal to 95% and the viscosity index is more than or equal to 90. The base oil can ensure that the kinematic viscosity of the stamping electrostatic spraying rust preventive oil is 12-18mm 2 The viscosity is proper, the atomization performance of the rust-preventive oil is better, and the saturated hydrocarbon content and viscosity index of the base oil can ensure the service life (better oxidation resistance) and acid value of the oil.
As for the rust inhibitor, in the present embodiment, the rust inhibitor may be at least one of barium sulfonate, calcium sulfonate, naphthenate, dodecenyl succinic acid ester, N-oleoyl creatine, benzotriazole. Preferably, the rust inhibitor may be at least one of barium sulfonate, naphthenate, and dodecenyl succinate. The selected antirust agent does not contain waxing components, is easier to clean later, and improves the cleaning property of the stamping electrostatic spraying antirust oil. In the scheme of the embodiment, the most preferred antirust agent combination is also provided, wherein the antirust agent can be a combination of barium petroleum sulfonate, zinc naphthenate and N-oleoyl sarcosine octadecylamine, and the mass ratio of the barium petroleum sulfonate, the zinc naphthenate and the N-oleoyl sarcosine octadecylamine is 10:4:1. the N-oleoyl sarcosine octadecylamine has the advantages of damp heat resistance and salt fog resistance superior to sulfonate type antirust agent, strong polarity, small solubility in oil, and zinc naphthenate is dissolved in mineral oil, has a certain dissolution assisting effect on a strong polarity corrosion inhibitor, has obvious damp heat resistance effect on ferrous metals, has neutralization and replacement property on sweat, has insignificant antirust effect on red copper, brass and bronze, has unsatisfactory anti-overlapping property, and has poor salt fog resistance, but can enhance the antirust effect on cast iron when being matched with barium petroleum sulfonate, so the barium petroleum sulfonate, zinc naphthenate and the N-oleoyl sarcosine octadecylamine can ensure excellent antirust performance according to specific combination collocation, and can ensure the longest salt fog antirust period and damp heat antirust period compared with other antirust agent combinations.
As for the lubricant, in the present embodiment, the lubricant may be a phosphorus-containing lubricant, a high base number sulfonate, a sulfur-containing extreme pressure agent, a synthetic ester oiliness agent, or the like. Regarding the design and improvement of lubricating performance, the research direction of stamping rust preventive oil at the present stage is mainly focused on greatly improving the extreme pressure lubricating property of the rust preventive oil by supplementing components such as a sulfur-containing extreme pressure agent, synthetic ester and the like, so that the stamping rust preventive oil can meet the requirements of large deformation and complex stamping. However, the sulfur-containing extreme pressure agent often has obvious pungent odor and is not suitable for the rust preventive oil for electrostatic atomization spraying. The rust-proof oil is used as a stamping lubricating medium (different from special stamping lubricating oil) and is used in the working conditions of small deformation and simple deformation, so that the wear resistance and the lubricity of the oil (through P) are required to be paid more attention to B Values and coefficient of friction). In the present application, lubricant compositions are optimized for how to improve the antiwear lubricity of rust preventive oil. Tests show that the phosphorus-containing lubricant and the high-base-number petroleum calcium sulfonate have better synergistic effect, and the compounding scheme can obviously improve the antiwear property of the oil product.
Preferably, the lubricant may be a combination of a phosphorus-containing lubricant and high base number calcium petroleum sulfonate, the mass ratio of the phosphorus-containing lubricant to the high base number calcium petroleum sulfonate being 1: (0.5-2), whereinThe phosphorus-containing lubricant can be ammonium phosphate or acid phosphate, and the base number of the high-base-number petroleum calcium sulfonate is more than or equal to 395mgKOH/g. The calcium sulfonate can be used as an antirust agent, but the higher the base number is, the better the lubricating performance is, so the high-base number calcium sulfonate can also be used as a friction reducer. Experiments prove that the lubricant adopting the combination of the dosage can ensure that the friction coefficient of the oil product is minimum, the lubricity is best, and the antiwear performance of the oil product is best: p (P) B The value is the largest and the value cof is the smallest.
Considerations regarding cleaning and atomization performance. The atomization performance and washability of the electrostatic spraying rust preventive oil are unique attributes of the electrostatic spraying rust preventive oil, which are different from other rust preventive oils, so that special consideration is needed when designing a scheme of stamping electrostatic spraying rust preventive oil: (1) the atomization performance influences the spraying effect of the stamping electrostatic spraying rust preventive oil, and the atomization performance of the stamping electrostatic spraying rust preventive oil can be represented by testing the surface tension of the oil; meanwhile, the spray coating can be performed on the oiling machine, and the actual jet length (the length of the position where the rust preventive oil starts to be atomized from the knife beam) and the atomization angle are compared. (2) Cleanability may be optimized by designing the composition of the stamping electrostatic spray rust inhibitive oil. By optimizing the surfactant, on one hand, the surface tension of the rust-preventive oil can be reduced, the atomization performance is improved, and on the other hand, the surfactant can ensure that the oil can be emulsified quickly in the cleaning process, and the washability of the oil is improved.
Regarding the surfactant, in the present embodiment, the surfactant may be at least one of span-80, alkylphenol ethoxylates, fatty alcohol ethoxylates, ethylene glycol monobutyl ether, and sodium petroleum sulfonate. Preferably, the surfactant is a combination of span80 and sodium petroleum sulfonate having a molecular weight of 500 or less, wherein the mass ratio of span80 to sodium petroleum sulfonate having a molecular weight of 500 or less is 1: (0.5-1), the petroleum sodium sulfonate is generally used as an antirust agent, and the petroleum sodium sulfonate with the molecular weight less than or equal to 500 has stronger emulsifying capacity, can meet the decontamination cleaning effect when an antirust workpiece is cleaned, and has better effect when being used together with span-80. The surfactant combined by the dosages has the following advantages: (1) the cleaning effect of the oil product is optimal; (2) the best atomization performance of the oil product can be characterized by jet length and atomization angle.
Regarding the antioxidant, in the present embodiment, the antioxidant is preferably at least one of a phenolic antioxidant and an aminic antioxidant. In embodiments of the present application, the antioxidant is preferably 2, 6-di-tert-butyl-p-cresol. In the process of storing and using the stamping electrostatic spraying rust preventive oil, free radical chain degradation reaction usually occurs under the actions of light, heat, metal and the like, so that the oil is precipitated or gelled to deteriorate, and the addition of the 2, 6-di-tert-butyl-p-cresol can prevent or slow down the oxidative deterioration of the stamping electrostatic spraying rust preventive oil.
A test method for lubricating properties. The four-ball friction and wear testing machine is widely applied to the lubrication performance test and characterization of lubricating oil, processing fluid and other mediums, wherein P B Maximum no-bite load, P D The value is the minimum sintering load. However, in the test process of the method, the upper friction pair and the lower friction pair are steel balls, the contact mode is point-point contact, and the friction pairs rotate at high speed and are inconsistent with the point-surface contact and the slow motion in the stamping process. The lubricating properties of the stamping electrostatic spray rust inhibitive oil in the examples and comparative examples were tested in this application using the reciprocating frictional wear test method for the actual friction characteristics of the stamping process: the upper friction pair is a steel ball, the lower friction pair is a steel plate, and slow and adjustable load movement is arranged between the upper friction pair and the lower friction pair.
The application also provides a preparation method of the stamping electrostatic spraying rust preventive oil, which comprises the following steps:
(1) firstly, adding 150N paraffin base and 60N paraffin base into a clean beaker according to a proportion, fully mixing, and stirring at 55-60 ℃ until the solution is transparent;
