Zirconia loaded metal antirust paint and its preparation method

Abstract

The invention discloses a zirconia loaded metal antirust paint and its preparation method. The metal antirust paint comprises the following raw materials, by weight, 35-40 parts of an epoxy resin, 15-20 parts of a polytetrafluoroethylene resin, 23-28 parts of modified nanometer argil, 9-11 parts of zirconia, 8-10 parts of a butadiene-styrene latex, 1.3-1.8 parts of a tallow amine, 15-20 parts of polycaprolactone, 0.7-0.9 parts of glycerol monostearate, 0.4-0.6 parts of polybutylene terephthalate, 0.7-0.9 parts of poly-4-methyl-1-pentene, 0.4-0.6 parts of salicylic acid, 0.5-1.0 part of an oxidant 168, 3-5 parts of a modified styrene-acrylate emulsion, 0.8-1.2 parts of polyacrylic acid, 0.6-1.2 parts of vinyl-tri(beta-methoxyethoxy)silane, and 1.0-1.2 parts of fatty alcohol polyoxyethylene ether. The film of the metal antirust paint has the advantages of good adhesion, fast drying, good heat resistance, environmental protection and no pollution, the modified nanometer argil and the modified styrene-acrylate emulsion which are added into the raw materials improve the excellent performances of high-polymer materials in the raw materials, and simultaneously increase the corrosion and heat resistances of the metal antirust paint, and the preparation method has the advantages of simplicity, low cost and suitableness for large-scale production.

Description

technical field [0001] The invention relates to a metal antirust paint loaded with zirconia and a preparation method thereof, belonging to the technical field of antirust materials. Background technique [0002] In recent years, epoxy zinc-rich paint is the most used industrial anti-rust 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; the viscosity of the paint will also increase when the anti-settling agent is added. 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 , to add a large amount of solvent to the paint, the solvent seriously endangers the health of workers during construction, the solvent volatilizes into the air during the drying process ...
