Abstract

The invention discloses thermosetting acrylic powder paint for ceramics. The thermosetting acrylic powder paint for ceramics is prepared from the following raw materials: hydroxyethyl methylacrylate, benzoic acid, acrylic acid, butanol, cumene peroxide, modified polyethylene terephthalate gum, a leveling agent, dimethyl benzene, azodiisobutyronitrile, ethanol amine, a plasticizer, manganese naphthenate, isocyanate, titanium dioxide and styrene. The thermosetting acrylic powder paint for ceramics has glossiness of 130%-150%, a gloss retention rate of 92-96% after manually accelerating ageing for 500 hours, shore hardness of 45-65, no bubbling and dropping phenomena after being soaked in water for 30-60 days, no abnormity after being soaked in 5% hydrochloric acid solution for 25-35 days, adhesion of levels 1-2, impact strength of 500-600N / cm, no bubbling and wrinkling phenomena after being soaked in saturated calcium hydroxide for 30-40 days, a product smelting point of 150-160 DEG C and density of 120-140g / cm<3>.

Description

technical field [0001] The application belongs to the field of coatings, in particular to a thermosetting acrylic powder 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. Its main raw material is silicate minerals (such as clay, quartz, etc.) taken from nature, so it belongs to the category of "silicate industry" togethe...
