Description
The present invention is a kind of corrosionproof lubricant coating based on molybdenum disulfide, this coating has good wear-resisting, carrying, lubricated and antiseptic property, the metal sliding part that is coated with this coating can solve the lubricated and anticorrosion problem that sliding part exists in the machinery industry of coastland in the medium-term and long-term use of the atmospheric environment of high humidity.
The dry film lubrication technology is the novel lubricating technology that grows up along with the development of new high-tech industries such as aerospace, be the effective means that solves lubrication problem under the harsh working condition, but one of its shortcoming is a shortage even do not have protective capacities in corrosive atmosphere (humidity, salt fog, corrosive gases).Because the crystal of molybdenum disulfide surface as main ingredient generates acidic substance with regard to the energy oxidation at a lower temperature; Graphite then can cause galvanic corrosion.In addition, opposite with general protective coating, the tackiness agent content during coating is formed is lower, only accounts for the part of solid ingredient, is difficult to form protective layer.At present with regard to the molybdenum disulfide base lubricating coating of domestic development, at slip coating through about 10 microns of sprayings on the parkerized soft steel test plate (panel), carry out salt-fog test by GB/T 1771-91, generally super only 100 hours of its salt spray resistance, and domestic many units particularly usually require it to have good corrosion prevention performance concurrently when selecting this lubricant for use in the coastland.
The objective of the invention is to overcome general slip coating on antiseptic property deficiency and provide a kind of and have concurrently lubricated and all good corrosionproof lubricant coating based on molybdenum disulfide of antiseptic property, and provide the preparation method of coating simultaneously.
Purpose of the present invention can realize by following measure:
Corrosionproof lubricant coating based on molybdenum disulfide is made up of tackiness agent, toughner, solidifying agent, lubricant and sanitas etc.Tackiness agent is a Resins, epoxy, and toughner is nbr carboxyl terminal, and solidifying agent is a resol, and lubricant is a molybdenumdisulphide, and sanitas is made up of antimonous oxide and/or plumbous oxide and synthetic wax.The weight percent of each component concentration is in the coating:
Resins, epoxy 1～10
Resol 2～15
End carboxyl butyronitrile 1～5
Molybdenumdisulphide 4～25
Antimonous oxide 1～5
Plumbous oxide 0～2
Synthetic wax 0.5～3
Organobentonite 0～1
The mixed solvent surplus
Select for use the Phenolic Resin with Epoxy Resin system as tackiness agent, the cohesive strength of dry film coating and wear resisting property are guaranteed.Selected Resins, epoxy is amino four sense Resins, epoxy, and softening temperature is 10～20 ℃, and oxirane value is 0.75～0.85; The hydroxy radical content of selected resol is 15～25%.
Select for use nbr carboxyl terminal as toughner, the toughness of dry film coating and antiseptic property are improved.Because generally be used for the paracril of modified epoxy is the less liquid acrylonitrile butadiene rubber of molecular weight, with Resins, epoxy can blend, Resins, epoxy is external phase in its cured product, paracril is a disperse phase, though this structure can reach toughness reinforcing purpose, but because its structure is by two phase composites, then its antiseptic property is difficult to be guaranteed.The selected carboxyl end of the liquid acrylonitrile-butadiene rubber of the present invention at high temperature, can react with Resins, epoxy, the toughness segment of rubber is introduced in the crosslinking structure of epoxy glue, makes cured product become the crosslinking structure of single phase, played intrinsic toughening and prevented that aqueous vapor is to the effect of ground corrosive.
The molybdenum disulfide lubricant that the present invention is selected, its purity should be greater than 98%, and granularity should be less than 5 microns.
The selected inorganic corrosion inhibitor of the present invention is antimonous oxide and/or plumbous oxide, these two kinds of oxide compounds not only have good synergistic with molybdenumdisulphide, its abrasion property is improved, and can improves the barrier propterty of its coating, its purity should be greater than 98%, and granularity should be less than 5 microns.
The selected organic anti-corrosive agent of the present invention is a synthetic wax, is characterized in the little poor permeability of density, can float in the preparation process of coating to the coating top layer, forms one deck protective layer, stops aqueous vapor to see through, and the barrier propterty of coating is greatly enhanced; And synthetic wax itself has good lubricating property, can not produce negative interaction to the lubricity of coating.Its fusing point is that the perviousness under 90～110 ℃, room temperature is 1.0～3.0, density is 800～1100kg/m

The selected thickening material of the present invention is an organobentonite, and its purity should be greater than 98%, and granularity should be less than 5 microns.
The selected solvent of the present invention is a mixed solvent, and its composition (volume percent) is:
Acetone 10～30%, butanone 20～50%, toluene 20～50%, ethylene glycol ethyl ether 10～25%.
Corrosionproof lubricant coating based on molybdenum disulfide of the present invention, its solid content are about 20% to be advisable.
Embodiment of the present invention are: take by weighing Resins, epoxy and nbr carboxyl terminal in ratio of the present invention, with its mixture prepolymerization reaction 1～2 hour under 120 ℃ condition; Solid lubricant and other modified filler is mixed in ratio of the present invention, put into ball grinder, adding an amount of mixed solvent grinds, be distributed to and add tackiness agent (performed polymer and the resol that promptly add Resins, epoxy and nbr carboxyl terminal) behind the desired particle size and grind half an hour, the mixed solvent that adds surplus again gets final product.With spray gun the coating for preparing is sprayed on piece surface under pressurized air (not having oil) or compressed nitrogen.Piece surface needs surface treatment such as oil removing, rust cleaning in advance.Part room temperature in clean air that spraying is good was placed more than 5 hours, put into convection oven again and solidified.Condition of cure: 150 ± 2 ℃, constant temperature 30 minutes; 180 ± 5 ℃, constant temperature 1 hour can use after the taking-up.
