Abstract
The invention discloses a high molecular metal anticorrosion paint and a preparation method thereof. The preparation method mainly comprises the steps of mixing and stirring raw materials of bisphenol A type epoxy resin, nanometer calcium carbonate, tetramethylsilane, straw ashes, butyl acetate, propylene glycol, vermiculite powder, dibutyltin dilaurate, chlorinated paraffin and chlorinated alkene in parts by weight and then dispersing the mixed raw materials to obtain a finished product. The high molecular metal anticorrosion paint prepared by using the invention has the advantages of good film adhesion, rapidness in drying, good thermal resistance, environment friendliness and no pollution; moreover, the preparation method disclosed by the invention has the advantages of simplicity, low cost and suitability for large-scale production.
Description
Technical field
The present invention relates to a kind of high molecular metal anticorrosion paint and preparation method thereof, is the N-BUTYL ACETATE by macromolecule, is applicable to coastland atmosphere industrial antisepsis.
Background technology
Adopted in recent years industry anti-corrosion paint protect metal take the epoxy zinc-rich lacquer 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 lacquer; The viscosity of the adding lacquer 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 lacquer 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 large behind the small molecular weight resin solidification, 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), the addition of magnalium zinc alloy in antifouling paste only just can obtain optimum for about 50% of zinc powder coating performance occurs; 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.
