Abstract

The invention relates to a color-changing antifouling paint, which comprises a component A and a component B. The component A consists of 20-40 parts of 3-diethylamino-7, 8-benzofuran, 10-18 parts of isopropylidene bisphenol, 3-5 parts of hexadecanol, 5-15 parts of an ethylene-maleic anhydride copolymer, 0.5-2 parts of lithium dimethyl-cuprate, and 5-30 parts of cyclohexanone, and the component B consists of 15-50 parts of crystal violet lactone, 30-65 parts of gallic acid dodecyl ester, 5-10 parts of lauric acid, 1-3 parts of iso-aldehyde naphthalene, and 0.5-3 parts of fumed silica. The color-changing antifouling paint provided by the invention has a wide color-changing temperature scope ranging from -100DEG C to 280DEG C, and has good antifouling effect.

Description

Technical field [0001] The invention relates to the field of coatings, and specifically to a color-changing coating. Background technique [0002] Coating is a kind of material, which can be coated on the surface of the object with different construction techniques to form a solid film with firm adhesion, certain strength, and continuous. The film formed in this way is generally called a coating film, also called a paint film or coating. It is an organic chemical polymer material, and the formed coating is of the type of polymer compound. According to the modern classification of chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a class of multifunctional engineering materials and an important industry in the chemical industry. The coatings currently on the market have relatively simple functions and cannot meet people's needs. [0003] Color-changing paint refers to a special paint whose color changes with environmental condit...
