Abstract
The invention discloses a high molecular epoxy resin metal anticorrosion paint and a preparation method thereof. The preparation method mainly comprises the steps of mixing and stirring raw materials of epoxy resin E20, nanometer calcium carbonate, quartz powder, tetramethylsilane, straw ashes, butyl acetate, ethylene glycol, dinbutyltin dilaurate, attapulgite and chlorinated alkene in parts by weight and then dispersing the mixed raw materials to obtain a finished product. The high molecular epoxy resin 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 macromolecule epoxy resin metal anti-corrosion paint 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 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 the resin (E44) of small molecular weight when selecting polyamide resin as much as possible; 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 big behind the small molecular weight resin solidification, metal expand with heat and contract with cold be greatly when temperature variation paint film easily chap 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.
