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...

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 filmadhesion, 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 [0001] The invention relates to a polymer epoxy resin metal anticorrosion paint and a preparation method thereof, which is composed of polyamide resin with a large molecular weight and butyl acetate, and is suitable for atmospheric industry anticorrosion in coastal areas. Background technique [0002] In recent years, epoxy zinc-rich paint is the most used industrial anti-corrosion paint to protect metal. 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 during construction, a large amount of solvent should be added to...
