Abstract

The invention discloses a mirror-back protective coating based on a silicon coated film system. The protective coating comprises the following components in percentages by weight: 40 to 50% of waterborne organosilicone resin with a concentration of 60%, 6 to 15% of hexamethoxymethyl melamine formaldehyde resin, 3 to 6% of iron oxide red, 10 to 20% of aluminum tripolyphosphate, 4 to 8% of zinc oxide, 6 to 10% of talcum powder, 10 to 15% of heavy calcium carbonate, 2 to 5% of bentonite EW, 1 to 3% of Byk-346, 0.5 to 1.5% of Byk-024, 0.5 to 1.5% of Byk-019, 1 to 3% of Byk-180, 5 to 10% of propylene glycol methyl ether and 5 to 15% of deionized water. The mirror-back protective coating provided by the invention is different with a traditional glass coating, and a layer of silicon is coated onthe basis of chromium plating, so the mirror-back protective coating achieves better effects of preventing oxidation and aging of a coating surface and resisting corrosion and high temperature, and has good popularization value.

Description

【Technical field】 [0001] The invention relates to a protective coating for the back of a mirror, in particular to a protective coating for the back of a mirror based on a silicon coating system. 【Background technique】 [0002] Most of the existing coating systems are glass coatings, which cannot be coated with a layer of silicon on the basis of chrome plating, so that they cannot better prevent the paint surface from oxidation, aging, corrosion resistance and high temperature resistance. To this end, we propose a protective coating for mirror backs in silicon-based coating systems. 【Content of invention】 [0003] The main purpose of the present invention is to provide a protective coating for the back of the mirror based on the silicon coating system, which is different from the traditional glass coating, and it is to coat a layer of silicon on the basis of chrome plating, so that it has better protection against oxidation of the paint surface, The effects of aging, corro...
