Abstract

The invention belongs to the technical field of coatings. The invention relates to an acrylic carboxyl polyurethane powder coating for ceramics and a preparation method thereof. In the prior art, a ceramic coating is not hard and has poor flexibility, high temperature resistance, poor durability, pollution and like. The acrylic carboxyl polyurethane powder coating for ceramics solves the above problem. The acrylic carboxyl polyurethane powder coating for the ceramic is prepared from the following raw materials: epoxypropane, glycerinum, yttrium oxide, lysine diisocyanate, an additive, propylene diamine, terpilenol, acrylic acid, polydimethylsiloxane and L-alanine-N-carboxyl-anhydride. According to the acrylic carboxyl polyurethane powder coating for ceramics, the original excellent characteristics of the two-component acrylic acid and the polyurethane are maintained, the mechanical property, the flexibility and the chemical property are substantially improved, and the wear resistance,the corrosion resistance and the high temperature resistance are excellent, the durability is good, and the method can be widely used in the fields of industry, construction, chemical industry and thelike.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an acrylic carboxyl polyurethane powder coating for ceramics and a preparation method thereof. Background technique [0002] Ceramics is the collective name of pottery and porcelain, and it is also a kind of arts and crafts in our country. As far back as the Neolithic Age, our country has rough and simple painted pottery and black pottery. my country's traditional ceramic arts and crafts are famous all over the world for their high quality, beautiful shape and high artistic value. Traditional ceramics, also known as ordinary ceramics, are products fired with clay and other natural silicates as the main raw materials; modern ceramics, also known as new ceramics, fine ceramics or special ceramics, commonly use non-silicate chemical raw materials or artificial synthetic materials, such as Manufacture of oxides (alumina, zirconia, titanium oxide, etc.) and non-oxides (silicon nitri...
