Abstract
The present invention relates to a nontoxic thick epoxy paint made from one or more of E-51, E-44, E-20 and E-12 epoxy resins with the epoxy equivalent values of 0.08 to 0.54, a crboxyl-terminated nitrile rubber toughening agent, a 678 reactive diluent, a silane coupling agent (KH-550), nontoxic alcohols, ketone solvents, a T31 and 650 compound solidifying system, quartz powder of which the granularity is smaller than 120 meshes, silicon miropowder, fine sand and cement. The nontoxic thick epoxy paint has little acute toxicity; the cumulative toxicity (K) is greater than 5; the micronucleus test indicates that the nontoxic thick epoxy paint does not cause cancerogenic jumps. The nontoxic thick epoxy paint is used as an anticorrosive paint on the inner wall of a drinking water container, and the quality of the water conforms to the sanitary standard for drinking water in China. The thickness of the coating is from 1 to 3mm, and the paint can resist the corrosion of acids, bases and salts with the concentration of 10% to 20%.
Description
Non-toxic thick epoxy paint belongs to the chemistry painting industry technical field.
The generally all toxic and overweight coating of existing epoxy mortar, intensity be low, be difficult for solidifying under the low temperature and moisture environment.
The objective of the invention is to make the thin and intensity height of a kind of nontoxic, coating, under the low temperature and moisture environment, be easy to the solidified mastic coatings.
The present invention is made up of Resins, epoxy, modified amine curing agent, toughner, coupling agent, reactive thinner, solvent, filler.Meter by weight: select oxirane value at 0.08～0.54 normal E-51, E-44, E-20, E-12 100 parts of the Resins, epoxy of one or more combination wherein; Modified amine curing agent selects T31 (phenol, formaldehyde, quadrol condenses), and (auxiliary reagent factory, Kunshan, Kunshan City, Jiangsu Province produces, see " metallic corrosion and protection essentials tutorial ", volumes such as Chen Xujun, China Machine Press publishes 215 pages an of book) (auxiliary reagent factory, Kunshan, Kunshan City, Jiangsu Province produces with 650 (low molecule pa resins), see that " the quick grade of high of bonding and adhesive technology handbook is write, Sichuan science tech publishing house publishes in the book 617 pages) solidifying agent makes compound curing system (650 is again toughner simultaneously), and the T31 proportioning is 15～35 parts; 650 proportionings are 10～50 parts; Toughner is selected nbr carboxyl terminal for use, and its proportioning is 5～35 parts; Coupling agent selects silane resin acceptor kh-550 (γ-An Jibingjisanyiyangjiguiwan) (chemical plant, Gai County, Liaoning Province produces, see " 631 pages and 632 pages of bonding and adhesive technology handbook one book), and proportioning is 1～5 part; Reactive thinner selects 678 (neopentylglycol diglycidyl ethers) (Wuxi, Jiangsu Province resin processing plant produces, and sees " Wuxi resin processing plant epoxy resin product catalogue " the 8th page), and proportioning is got 5～50 parts; Solvent selects alcohols, the ketone of nontoxic type, and proportioning is got 100～700 parts; Filler selects the nontoxic type filler, and the proportioning of cement is 50～350 parts; Particle diameter is 100～700 parts, the particle diameter fine sand at 0.10～2mm less than the silica powder proportioning of 90 μ m (＜120 order), and proportioning is 100～700 parts; The proportioning of silicon powder is 10～700 parts.(all cooperation ratios are 100 in Resins, epoxy all).
The toxicity that coating of the present invention gives environmental health monitoring and surveilliance institute of anti-medical scientific institute through China detects and the toxicity of Public Health College, Harbin Medical Univ is accredited as: acute toxicity: nontoxic substantially; Cumulative toxicity: K＞5; Micronucleus test: no Cancer-causing mutation; Water examination: this coating is used as drinking-water pipe, tank inner wall anticorrosion coating: contain the drinking water quality inspection and meet national drinking water standard; Thick coating is at 1～3mm, and the general life-span is about 30 years; The corrosion of soda acid salt that can anti-10～20% concentration.
Embodiment one: take by weighing Resins, epoxy 100kg and go into reactor, take by weighing nbr carboxyl terminal toughner 20kg and go into reactor, start agitator, be heated to 150 ℃, reacted 2～3 hours.Be cooled to 40 ℃, adding alcohol solvent 60kg, 678 reactive thinner 20kg, silane resin acceptor kh-550 are 1kg, stir.Barrelling becomes the first component.
Take by weighing T31 solidifying agent 18kg, 650 solidifying agent 20kg go into the stirrer mixing.Add alcohol solvent 30kg again and continue to stir, dissolving evenly.Barrelling becomes component B.
Take by weighing filler cement 100kg, silica powder 400kg, silicon powder 100kg, fine sand 300kg mix, and go into drying room oven dry, standby third component that becomes.
During use by weight first: second: the third=3: choose at 1: 6, stir evenly use with stirrer.
Claims (1)
