Abstract

The invention discloses acrylic epoxy resin powder paint for ceramics. The acrylic epoxy resin powder paint for ceramics is prepared from the following raw materials: epoxy resin, methyl tetrahydrophthalic anhydride, butyl maleic acid, maleic anhydride, 2-methylimidazole, phthalic anhydride, a leveling agent, dimethyl benzene, 2-tert-butyl peroxide, propylene glycol, a plasticizer, cobalt iso-octoate butyl acetate, styrene, methyl ethyl ketone peroxide and n-butyl methacrylate. The acrylic epoxy resin powder paint for ceramics disclosed by the invention has the advantages that weather resistance is excellent and the glossiness is 100%-140%, bubbling and dropping phenomena can not generate after the paint is soaked in water for 30-40 days, drying time is 15-25 minutes, no abnormity generates after the paint is soaked in 5% hydrochloric acid solution for 25-35 days, adhesive force reaches levels 1-2, no bubbling and wrinkling phenomena generate after the paint is soaked in saturated calcium hydroxide for 20-30 days, shore hardness is 50-70H, and the paint has the capacity of not exposing bottom after being scrubbed for 1200-1800 times due to scrubbing resistance.

Description

technical field [0001] The application belongs to the field of coatings, in particular to an acrylic epoxy resin powder coating for ceramics. Background technique [0002] So far, the definition of ceramics seems to be generally described as follows: ceramics are made of aluminosilicate minerals or certain oxides as the main raw material, and are produced at a certain temperature and at a certain temperature according to the intention of the person through a specific physical and chemical process. A certain type of craft rock made of atmosphere. The surface can be glazed or unglazed, and some porcelains also have different degrees of translucency. The whole body is composed of one or more crystals or amorphous cements and microstructures such as pores or clinker inclusions. Due to the continuous development of ceramic science and technology. And the market's increasing demand for new ceramic products forces ceramic companies to continuously develop new products, and must c...
