Abstract

The invention discloses an ultraviolet photocuring alkene unsaturated polyester coating for ceramic. The coating is prepared from the following raw materials: bisphenol A butyl acetate glyceryl ether, carboxymethylcellulose, methylene-succinic acid, lithopone, n-butyl acetate, calcium carbonate heavy, a photosensitizer, talcum powder, acrylic acid, ultramarine, a cross-linking agent, sodium silicate, methacryloyloxyethyl isocyanate, zinc oxide and dibulytin dilaurate. The glossiness of the product, namely the ultraviolet photocuring alkene unsaturated polyester coating is 110-130%, and the coating coated in amyl acetate in 1-3 days is free from bubbling and shedding phenomena. The coating is acetone-resistant and is free from abnormalities after being rubbed by a cotton ball soaked by 5% ammonium water for 24-48 hours. The coating is free from bubbling and wrinkling after being soaked in a 95% ethanol solution for 12-36 hours. The scrub resistance of the product reaches 600-800 times, and can be widely produced and continuously replace existing materials.

Description

technical field [0001] The application belongs to the field of coatings, in particular to an ultraviolet photocurable ethylenically unsaturated polyester coating for ceramics. Background technique [0002] The ceramic industry is developing rapidly in our country, and the sales market is gradually booming. my country is a big country producing ceramics, and the demand for ceramics is also increasing. From the perspective of the domestic market situation, the situation in recent years is gratifying. The supply of famous, premium and high-quality new ceramic products is in short supply. High-grade ceramics and medium-to-high-end sanitary ceramics are very popular. Ceramics are various products made of natural clay and various natural minerals as the main raw materials through crushing, kneading, molding and calcination. In the past, people called ceramics made of clay and fired at high temperature in special kilns. Ceramics is the general term for pottery and porcelain. The...
