Problems solved by technology

Due to the relatively high density of metal zinc powder, in order to prevent the zinc powder from settling or slow down the settling speed of the zinc powder, it is necessary to add a certain amount of anti-settling agent to the paint; the viscosity of the paint will also increase with the addition of the anti-settling agent Therefore, when selecting polyamide resin, it is necessary to choose a resin with a small molecular weight (E44) as much as possible; in order to meet the brushability d...

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, lowcost and suitability for large-scale production.

Description

Technical field [0001] The present invention involves a polymer metal anticorrosive paint and its preparation method. It is composed of polyamide resin and acetate with large molecular weight, which is suitable for the atmospheric industrial anti -corrosion of the atmospheric industries in coastal areas. Background technique [0002] In recent years, industrial anticorrosive paint has been used to protect metal with the most epoxy zinc -rich paint.Because the density of metal zinc powder is relatively large, in order to prevent zinc powder from falling or slowing the speed of zinc powder, a certain amount of anti -sinking reduction is needed to the paint;When choosing a polyamide resin, choose the resin (E44) of small molecular weight as much as possible; in order to satisfy the brushing performance during construction, a large amount of solvents must be added to the paint.During the drying process, the solvent was volatilized into the air pollution environment and the solvents i...
