Abstract

The invention discloses a mirror plane wear-resistant nanometer polyester coating for a TMT industry. The mirror plane wear-resistant nanometer polyester coating is prepared from, by weight, 10-14 parts of 1,2-ethylidene-diisocyanate, 15-20 parts of poly-dimethyl-siloxane, 17-20 parts of fluorinated polyethylene, 0.4-1 part of divinyl benzene, 1-2 parts of azodicarbonamide, 3-5 parts of diacetone alcohol, 1-3 parts of trifluoroethyl methacrylate, 0.6-1 part of allylsulfocarbamide, 0.5-1 part of tert-Butylhydroquinone, 0.7-2 parts of zinc acetylacetone, 2-5 parts of butylmercaptooxo stannane, 3-6 parts of stannous sulfide and 3-4 parts of silica powder. Through organic treatment of inorganic filler, the dispersity of all raw materials of the coating is improved, the compatibility between filler and polymers is improved, and the stability and strength of coating film is improved.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a mirror anti-wear nanometer polyester coating for TMT industry and a preparation method thereof. Background technique [0002] The functional coating of LOW-E glass currently on the market mainly plays a role in heat insulation is a silver layer. Silver has good infrared reflection performance, but silver is easily oxidized when it is in contact with air and processed. The silver oxide formed after oxidation is opaque, and has low adhesion, narrow heat insulation range, and complicated process, which reduces the stability of LOW-E glass. Therefore, at least two layers of silicon dioxide and several layers of other materials should be coated to protect it from oxidation or minimize its impact on light transmission; [0003] With the development of the electronics industry, especially the promotion and application of smart phones, large-screen TVs, and smart tablet computers, ...
