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 epoxide alloy antifouling paste and preparation method thereof, form, be applicable to coastland atmosphere industrial antisepsis by polyamide resin, the N-BUTYL ACETATE of macromolecule.
Background technology
What adopted in recent years that industry anti-corrosion paint protects metal serves as maximum with the epoxy zinc-rich lacquer.Because the density of metal zinc is bigger, in order not make the settling velocity of the zinc powder sedimentation or the zinc powder that slows down, need in lacquer, add a certain amount of anti-sedimentation agent; The viscosity of the adding lacquer of anti-settling agent also increases thereupon, when selecting polyamide resin, will select the resin (E44) of small molecular weight as much as possible; In order to satisfy brushing property, in lacquer, add a large amount of solvents during construction, solvent serious harm workman's healthy, lacquer solvent evaporates contaminate environment, making of solvent in the air in drying process improved construction cost during construction; The fragility of paint film is big behind the small molecular weight resin solidification, metal expand with heat and contract with cold be greatly when temperature variation paint film be prone to be full of cracks or come off.
Magnalium zinc alloy density is little, theoretical electric weight big (for 3.6 times of zinc), the addition of magnalium zinc alloy in antifouling paste only just can obtain optimum for about 50% of zinc powder coating performance takes place; Coating resistance is up to more than the 500K Ω .cm2; Electropotential can be stabilized in for a long time-and below the 0.85v (SCE), one coat effectively protects the life-span to be 1 year.
