Environment-friendly wear resistant and high-weather resistant polyurethane enamel and preparation method thereof

Abstract

The present invention provides an environment-friendly, wear-resistant and highly weather-resistant polyurethane enamel and a preparation method thereof. The enamel includes the following components: Component A: water-based hydroxyacrylic resin, water-based polyurethane emulsion, hydroxymethyl cellulose, titanate coupling agent , Stabilizer, leveling agent, wetting and dispersing agent, emulsifier, pigment and filler, deionized water; component B: water-based hexamethylene diisocyanate trimer. The enamel is composed of two components, with water-based hydroxyacrylic resin, water-based polyurethane emulsion and hydroxymethyl cellulose as the main components of A component, and water-based hexamethylene diisocyanate trimer as B component, which can Effectively improve the hardness of enamel paint film, the composition design is reasonable, dilute with deionized water as solvent, instead of organic solvent, friendly to the environment, improve wear resistance, strong adhesion, good ductility, high temperature resistance, long service life, When coating, roller coating is used instead of spray coating, which can effectively improve the production environment and benefit the health of workers.

Description

technical field [0001] The invention relates to an environment-friendly, wear-resistant and highly weather-resistant polyurethane enamel and a preparation method thereof. Background technique [0002] Enamel, also known as enamel, English enamel. It is made of varnish as the base material and added with pigments for grinding. After the coating is dried, it has a magneto-optical color and the coating film is hard. Commonly used are phenolic enamel and alkyd enamel, which are suitable for metal window screens and grids. It is mainly made of alkyd resin, which is ground by adding the required pigments and additives according to the requirements of various varieties; the main features are: good gloss, weather resistance, water resistance, strong adhesion, and can withstand the weather strong change. Uses: metal, wood, various vehicle machinery instruments and water steel components ships. [0003] Enamel paint is a kind of high adhesion and high anti-corrosion paint, which is...

Problems solved by technology

In the spraying workshop, enamel is the main source of volatile organic pollutants. When the concentration of volatile organic compounds in the air in the spraying workshop is too high, it is easy to cause acute poisoning. In mild cases, headache, dizziness, coughing, nausea, vomiting, or symptoms may occur. Drunkenness; in severe cases, liver poisoning and even coma will occur soon, and some may be life-threatening
