Self-cleaning flame-retardant corrosion-resistant fluorosilicone powder coating

Abstract

The invention discloses a self-cleaning flame-retardant corrosion-resistant fluorine-silicon powder coating. The coating is prepared from the following components in parts by weight: 50-60 parts of afilm-forming copolymer, 4-8 parts of amino-terminated hyperbranched compound quaternary ammonium salt, 1-3 parts of lignosulfonic acid, 0.1-0.2 part of phosphorus pentoxide, 3-7 parts of a functionalaid, 10-15 parts of an inorganic filler and 1-3 parts of rare earth fluoride nanofibers, wherein the film-forming copolymer is prepared from 2-trimethylsiloxy-1,1,1,5,5,5-hexafluoro-2-penten-4-one, (E)-4-(2-cyano-3-ethoxy-3-oxo-1-propenyl)phenylboronic acid pinacol ester, trimethyl 4-phosphonobutenoate, N-hydroxysuccinimide methacrylate and 1,3-bis(oxiranylmethyl)-5-(2-propenyl)1,3,5-triazinyl-2,4,6(1H,3H,5H)-trione through a free radical polymerization reaction. The powder coating disclosed by the invention is remarkable in self-cleaning effect, good in performance stability, corrosion resistance, weather resistance, wear resistance, film-forming property and flame retardance, excellent in bonding property with a base material, superior in comprehensive performance, and safe and environment-friendly to use.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a self-cleaning flame-retardant and corrosion-resistant fluorosilicon powder coating and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of my country's economy, the building and its supporting decoration industry have simultaneously entered an era of unprecedented rapid development. Coatings, as a common building decoration material, have been more and more widely used in industry, agriculture, national defense, scientific research and people's lives. There are more and more varieties of coatings on the market, and their quality and performance are constantly improving. Many functional coatings It has gradually occupied a large market share and has been sought after by consumers. It has become the "darling" of the coatings market at present and in the future, and has very high market potential. [0003] Paint is a ki...
