Description
Technical field
The invention belongs to technical field of coatings, and in particular to a kind of automobile chassis antirusting paint.
Background technology
Automobile chassis is the part that most complicated, worst environment is subjected in automotive service life, from new car it is offline go out
To scrapping, chassis subjects always the mission of support vehicle body for factory, experiencings the attack for the sandstone that the wheel of high-speed rotation is rolled, with
When be faced with the etches such as rain, snow, mud, further encounter the scratch and destruction on bumpy road surface once in a while.These severe use items pair
The chassis plate for only doing simple preservative treatment is difficult to bear:Sandstone between not, which is hit, can lead to the anti-of chassis plate
Rust surface is seriously destroyed, and brand-new substrate of steel plate is easy to be got rusty by the dioxygen oxidation in air again, and especially air pollution is serious, goes out
Situations such as existing acid rain, on the road surface that chemical substance disappears snow and ice, the corrosion threat that chassis faces is even more serious.With society
Development, the ownership of automobile is increasing, and the new markets and repairing market of automobile chassis nursing coating suffer from tempting huge
Potentiality, economic benefit and social benefit are all very considerable.But with the fast development of Chinese Automobile Industry ', the environmental protection that faces
Pressure is also increasing, and domestic automobile industry generally uses traditional solvent based coating in automobile chassis spray painting.VOC
Content is high, is producing and is causing serious environmental pollution in coating process, is endangering the health of the mankind.Reduce automobile chassis nursing
VOC emission of the coating in production and application must just use environment-friendly type coating, wherein water paint to replace having with a large amount of water
Solvent is greatly reduced with the volatile quantity of organic solvent in work progress producing, is an important development side of environmental protection coating material
To therefore, developing a kind of automobile chassis protection water paint has great Practical significance.
Invention content
The purpose of the present invention is for existing problem, provide a kind of automobile chassis antirusting paint.
The present invention is achieved by the following technical solutions：
A kind of automobile chassis antirusting paint, is made of following component by weight：Acrylic emulsion 75-80, xanthans 10-
15, antifoaming agent 0.5-0.8, dispersant 0.3-0.6, coalescents 1.2-1.5, barium sulfate 5-10, modified zinc phosphate 6-8, surface
Activating agent 0.8-1.2, isotridecyloxypropylpolyoxyethylene polyoxyethylene base propyl amine 2-5, nano aluminium oxide 3-6, talcum powder 3-6, tbp 2-4, oxygen
Change starch 8-12, sepiolite powder 1-3, chlorinated paraffin 3-5.
Further, the dispersant is polyacrylamide.
Further, the antifoaming agent is polypropylene glycerol aether.
Further, the modified zinc phosphate preparation method is：
By the trbasic zinc phosphate zinc phosphate solution soluble in water for being configured to mass fraction and being 10%, its quality is added into zinc phosphate solution
30% absolute ethyl alcohol after stirring evenly, is heated to 60 DEG C, keeps the temperature 10min, then trbasic zinc phosphate mixing alcoholic solution adds phosphoric acid again
The organo silane coupling agent of zinc mixed alcohol solution quality 2.5% is stirred 2 hours with 1200r/min rotating speeds, then carries out rotation steaming
It is dry dry to get modified zinc phosphate.
Further, the surfactant is neopelex.
Further, the coalescents are propylene glycol methyl ether acetate.
Further, the oxidized starch preparation method is：Soybean starch is distributed in deionized water, quality is configured to
The soybean starch slurries that score is 10%, the sodium hypochlorite of its quality 0.25% are added into soybean starch slurries, with 120r/min
Rotating speed stir 2 hours, be then filtered, drying to constant weight, then using 550W microwave treatments 3min to get.
The present invention has the following advantages compared with prior art：Automobile chassis antirusting paint prepared by the present invention, with acrylic acid
For lotion as basic film forming matter, it also contains modified zinc phosphate and iron rust chemically reactive in addition to containing general coating composition
Make harmful rust transformation be it is harmless or have certain protective role, coating is because containing modified zinc phosphate, the effect to iron rust
Soon, it can be applied with rust, which, which can soak, penetrates into loose porous corrosion layer, is inert corrosion-free black object by rust transformation
Matter forms the closing film of continuous-stable on steel, has completely cut off corrosion of the extraneous corrosive medium to steel, reached effective
Antirust, anti-corrosive acts on.The coating only needs directly brush after simply removing floating rust, and Pretreatment Technology Before Finishing greatly simplifies, the duration
Shorten, construction cost is low.In addition the coating is that aqueous coating system VOC itself is low, environment friendly and pollution-free.Performance test and application knot
Fruit shows that coating attachment is strong, turn embroidery performance is good, antiseptic property is excellent, with alkyd, chlorinated rubber, epoxy, polyurethane, fluorine carbon
There is good compatibility etc. various conventional finishing coats, there is preferable anti-corrosion protection to act on automobile chassis, there is wide application
Foreground.
