Abstract
The invention discloses a kind of metal anticorrosive paint for automobile parts and preparation method thereof, its be mainly by constitutive material polyamide, barium sulfate, nano-calcium carbonate, tetramethylsilane, stalk ashes, butyl acetate, propane diols, dibutyl tin laurate, chlorinated paraffin and chlorinated alkenes by certain part by weight mix, dispersion after obtain finished product.The present invention prepare metal anticorrosive paint for automobile parts paint film adhesion is good, fast drying, heat-resist, it is environment friendly and pollution-free, and preparation method of the present invention is simple, low cost, is adapted to mass produce.
Description
Technical field
It is by the polyamide resin of macromolecule the present invention relates to a kind of metal anticorrosive paint for automobile parts and preparation method thereof
Fat, butyl acetate composition, it is adaptable to coastal area air industrial antisepsis.
Background technology
Used industry anti-corrosion paint in recent years protect metal with epoxy zinc-rich paint be most.Due to the density of metal zinc
Than larger, in order to not make zinc powder settling or slow down the sinking speed of zinc powder, it is necessary to add a certain amount of sagging inhibitor in paint；It is anti-settling
The viscosity of the addition paint of agent is consequently increased, and the resin of small-molecular-weight will be as much as possible selected when polyamide is selected
(E44)；In order to be able to meet brushability during construction, be to adding substantial amounts of solvent in paint, solvent serious harm workman during construction
Healthy, paint solvent in the drying process polluted in evaporateing into air environment, solvent make improve construction cost；Small molecule
The fragility of paint film is big after amount resin solidification, and the big paint film in temperature change of metal heat-expansion shrinkage system is easily cracked or comes off.
Magnalium kirsite density is small, theoretical generation electricity (being 3.6 times of zinc), magnalium kirsite adding in corrosion resistant coating greatly
Dosage is only 50% or so of zinc powder to be obtained with optimal coating performance, and coating resistance is up to more than 500K Ω .cm2, electricity
Electrode potential can long-time stable in -0.85v (SCE) below, it is 1 year that one coat effectively protects the life-span.
The content of the invention
In order to alleviate shortcomings and deficiencies of the prior art, present invention aim at a kind of auto parts and components anti-corrosion of metal of offer
Paint and preparation method thereof.
The present invention is adopted the following technical scheme that to achieve these goals：
Metal anticorrosive paint for automobile parts, it is characterised in that the weight portion of its constitutive material is：Polyamide 29-42
Part, barium sulfate 1-4 parts, nano-calcium carbonate 1-4 parts, tetramethylsilane 2-6 parts, 2-6 parts of stalk ashes, butyl acetate 7-15 parts,
Propane diols 10-16 parts, dibutyl tin laurate 1-5 parts, chlorinated paraffin 2-6 parts and chlorinated alkenes 4-12 parts.
The preparation method of described metal anticorrosive paint for automobile parts, it is characterised in that comprise the following steps：
1) by the weight portion of constitutive material by polyamide, barium sulfate, nano-calcium carbonate, tetramethylsilane and propane diols
Mixing and stirring, disperses at a high speed and is ground to below 35um fineness；
2) stalk ashes, butyl acetate, dibutyl tin laurate, chlorination are added by weight in above-mentioned reaction system
Paraffin and chlorinated alkenes, disperse at a high speed 4-12 minutes under 650-800 revs/min of rotating speed, obtain finished product.
Beneficial effects of the present invention：
The present invention prepare metal anticorrosive paint for automobile parts paint film adhesion is good, fast drying, heat-resist, environmental protection is without dirt
Dye, and preparation method of the present invention is simple, low cost, is adapted to large-scale production.
