Abstract
The invention discloses a nontoxic environment-friendly metal anticorrosive paint and a preparation method thereof. The paint is mainly composed of materials of polyamide resin, bisphenol A type epoxy resin, nano-grade calcium carbonate, tetramethyl silane, straw ash, butyl acetate, propylene glycol and chlorinated paraffin. The materials are mixed, stirred and dispersed according to a certain weight ratio, and a finished product is obtained. A paint film prepared from the nontoxic environment-friendly metal anticorrosive paint provided by the invention is advantaged in good adhesion, fast drying, good heat resistance, environment-friendliness, and no pollution. Also, the preparation method provided by the invention is advantaged in simple method, low cost, and suitability for large-scaled productions.
Description
Technical field
The present invention relates to a kind of asepsis environment-protecting metal anti-corrosion paint and preparation method thereof, formed by polyamide resin, the N-BUTYL ACETATE of macromolecule, be applicable to coastland atmosphere industrial antisepsis.
Background technology
That adopted in recent years that industry anti-corrosion paint protects metal take the epoxy zinc-rich paint as at most.Because the density ratio of metal zinc is larger, in order not make zinc powder settling or the settling velocity of the zinc powder that slows down, need in paint, add a certain amount of anti-sedimentation agent; The viscosity that adds paint of anti-settling agent also increases thereupon, when selecting polyamide resin, will select as much as possible the resin (E44) of small molecules amount; During construction, in order to meet brushing property, in paint, add a large amount of solvents, during construction, solvent serious harm workman's healthy, paint solvent evaporates in drying process makes to have improved construction cost to contaminate environment, solvent in air; After small molecules amount resin solidification, the fragility of paint film is large, metal heat-expansion shrinkage system greatly when temperature variation paint film easily chap or come off.
Magnalium zinc alloy density is little, theoretical electric weight large (for 3.6 times of zinc) occurs, the addition of magnalium zinc alloy in antifouling paste only just can obtain optimum coating performance for 50% left and right of zinc powder; coating resistance is up to more than 500K Ω .cm2; electropotential can be stabilized in for a long time-and below 0.85v (SCE), one coat effectively protects the life-span to be 1 year.
Summary of the invention
In order to alleviate shortcomings and deficiencies of the prior art, the object of the invention is to provide a kind of asepsis environment-protecting metal anti-corrosion paint and preparation method thereof.
The present invention adopts following technical scheme to achieve these goals:
The asepsis environment-protecting metal anti-corrosion paint is characterized in that the weight part of its constitutive material is: polyamide resin 30-40 part, bisphenol A type epoxy resin 20-30 part, nano-calcium carbonate 1-3 part, tetramethylsilane 2-5 part, stalk ashes 2-5 part, N-BUTYL ACETATE 8-15 part, propylene glycol 10-15 part and clorafin 2-5 part.
The preparation method of described asepsis environment-protecting metal anti-corrosion paint is characterized in that comprising the following steps:
(1) weight part by constitutive material stirs polyamide resin, bisphenol A type epoxy resin, nano-calcium carbonate, tetramethylsilane and mixed with propylene glycol, and high speed dispersion also is ground to below the 35um fineness;
(2) in above-mentioned reaction system, add by weight stalk ashes, N-BUTYL ACETATE and clorafin, at 700-800
