Abstract
The invention discloses an epoxy resin metal corrosion resistant paint and a preparation method thereof. The preparation method mainly comprises the steps of mixing the component raw materials of bisphenol A type epoxy resin, zinc phosphate, nanometer calcium carbonate, tetramethylsilane, straw ashes, butyl acetate, propanediol, dibutyltin dilaurate and chlorinated olefin according to a certain weight part and stirring and dispersing the mixture to obtain the finished product. The epoxy resin metal corrosion resistant paint prepared by the invention has good adhesive force, quick drying, good heat resistance, environmental protection and no pollution, and the preparation method provided by the invention is simple, is low in cost and is applicable to large-scale production.
Description
Technical field
The present invention relates to a kind of epoxy resin metal corrosion resistant paint and preparation method thereof, formed by polyamide resin, the N-BUTYL ACETATE of macromolecule, be applicable to coastland atmosphere industrial antisepsis.
Background technology
Adopted in recent years industry anti-corrosion paint protect 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 to add a certain amount of anti-sedimentation agent in paint; The viscosity that adds paint of anti-settling agent also increases thereupon, will select as much as possible the resin (E44) of small molecular weight when selecting polyamide resin; In order to satisfy brushing property, add a large amount of solvents in paint during construction, during construction, solvent serious harm workman's healthy, paint solvent evaporates contaminate environment, making of solvent in the air in drying process improved construction cost; After the small molecular weight 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 the coating performance of optimum 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.
