Abstract

The invention provides a preparation method of high-solid epoxy abrasion-resistant coating. The high-solid epoxy abrasion-resistant coating is prepared from a main agent and a curing agent. The main agent is prepared by the method comprising the following steps that epoxy resin 1, epoxy resin 2, active diluent, n-butanol, xylene, an anti-settling agent and a dispersant are sequentially added intoa reaction kettle and stirred at a high speed, and thus mixed liquor is obtained; under high-speed stirring, 600 meshes of talcum powder, feldspar powder, mica powder and iron oxide red are sequentially and slowly added into the mixed liquor, stirred for 30 min and thus fully mixed with the mixed liquor; and epoxy resin 1, a coupling agent, n-butanol, xylene, non-floating aluminum powder, a dispersant and xylene are sequentially added into the mixing liquor, uniform dispersing is conducted through high-speed shearing, and thus the main agent is prepared. The prepared method of the high-solid epoxy abrasion-resistant coating has the advantages and positive effects that the high-solid epoxy abrasion-resistant coating has excellent corrosion resistance and excellent corrosion resistance, canbear seawater immersion and has excellent surface adaptability.

Description

technical field [0001] The invention relates to the field of paint manufacturing, in particular to a preparation method of a high-solid epoxy wear-resistant paint. Background technique [0002] Epoxy resin has the advantages of strong adhesion, high hardness, wear resistance, acid and alkali resistance, etc., so it is widely used in heavy-duty anti-corrosion paint, ship paint, container paint, etc., especially epoxy paint. With the rapid development of the economy, modern industries, office environments, hospitals and other public places have higher and higher environmental requirements, and traditional coatings are difficult to meet the requirements of modern industries. Traditional solvent-based epoxy paint will discharge a large amount of organic solvents (VOC) during production, construction, and curing, causing environmental pollution and affecting human health. In recent years, countries around the world have formulated corresponding regulations on coatings to limit t...
