Abstract

The invention relates to a special anti-corrosion coating for ceramics and a preparation method thereof. The anti-corrosion coating for ceramics is composed of pentaerythritol hexaacrylate, N-methylpyrrolidone, zirconium quartz, porcelain powder, polydimethylsiloxane, and butyl hexanediol Ether acetate, dodecyl alcohol ester, attapulgite, antifreeze, sodium hexametaphosphate, and gull gum; the special anti-corrosion coating for ceramics prepared by the invention has excellent mechanical properties, high strength, and good toughness , good adhesion with ceramics, no shedding, layering, good wear resistance, long service life.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a special corrosion-resistant coating for ceramics and a preparation method thereof. Background technique [0002] With the development of society and the improvement of human living standards, the requirements for quality of life are getting higher and higher. Ceramic utensils are used more and more in modern life, and there are various types. At the same time, ceramic utensils have high safety and good aesthetics. Its characteristics occupy an indispensable position in daily life. As we all know, ceramic utensils also have certain shortcomings, such as brittle quality and easy wear and tear, etc., which often require paint coatings as protective films to enhance their surface strength and prolong their service life. The coatings currently used for ceramics can make ceramic utensils have better strength and wear resistance, greatly improving their performance, but ...
