Abstract

The invention discloses a radiation curable acrylate resin coating for ceramics. The coating is prepared from the following raw materials: epoxy acrylate, trioctyl trimellitate, xanthone, mercaptan dibutyltin, triethylamine, trimethylolpropane triacrylate, a photoinitiator, PVC (polyvinyl chloride) resin, hydroxyethyl methylacrylate, DOP (dioctyl phthalate), a crosslinker, dibutyltin dilaurate, isopropanol, titanium dioxide and rutile titanium dioxide. The coating has the adhesion force of 1-2 grade, the hardness of 9-12H and the glossiness of 100%-130%, cannot fall off and generate an abnormal state when being soaked in a 5% hydrochloric acid solution for 24-48 hours, cannot cause bubbling and wrinkling when being soaked in saturated calcium hydroxide for 3-5 days, can be washed and brushed for 1200-1500 times, and can be extensively produced to continuously replace an existing material.

Description

technical field [0001] The application belongs to the field of coatings, in particular to a radiation-cured acrylate resin coating for ceramics. Background technique [0002] 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 traditional concept of ceramics refers to all artificial industrial products that use inorganic non-metallic minerals such as clay as raw materials. It includes various products made of clay or a mixture containing clay through kneading, shaping, and calcination. It ranges from the roughest earthenware to the finest fine pottery and porcelain. So far, the definition of ceramics seems to be generally described as follows: ceramics are made of aluminosilicate minerals or certain oxides as the...
