Anticorrosive anti-yellowing coating for glass door and preparation method of coating

Abstract

The invention discloses an anticorrosive anti-yellowing coating for a glass door. The coating is characterized by being prepared from the following raw materials in parts by weight: 8 to 12 parts of water-based vinyl polyurethane, 30 to 35 parts of amino resin emulsion, 0.1 to 0.3 part of water-based silane coupling agent KH460, 26 to 32 parts of modified styrene-acrylic emulsion, 1 to 3 parts of dipropylene glycol dimethyl ether, 0.3 to 0.5 part of alcohol amine alkoxy titanate ester, 0.2 to 0.4 part of fluoro-alkyl polyether modified polysiloxane, 0.1 to 0.3 part of lauroyl diethanolamide, 0.2 to 0.3 part of white oil, 0.2 to 0.4 part of polyoxyethylene sorbitan monooleate, 0.1 to 0.2 part of ammonium polyphosphate, 0.3 to 0.7 part of ethylparaben, 0.2 to 0.5 part of glycerin, 0.3 to 0.6 part of quartz powder, 1 to 3 parts of pigment and 10 to 15 parts of deionized water. The sterilization, the dust prevention, the anti-static performance and the like of the coating are improved due to the added modified styrene-acrylic emulsion; the coating has the functions of sterilization and anticorrosion due to the added ethylparaben; and on the basis of water resistance, acid resistance and an excellent adhesive force of the water-based coating, the water-based coating is also good in weatherability, aging resistance and anticorrosion.

Description

Technical field [0001] The present invention involves a coating and preparation method, especially a coating method and its preparation method for anticorrosive yellow -resistant glass doors. Background technique [0002] As people's living standards are increasingly improved, people's pursuit of beauty is becoming stronger and stronger. Glass partitions, glass bathrooms, etc. should be used as glass doors as home decoration glass and glass products.The needs, but with the continuous expansion of the application field, the requirements of the functional characteristics of glass coatings have been put on increasingly higher requirements, which has far exceeded the requirements of traditional decoration and beautification. Since the current glass coatings are mostly solvent -based coatings, when the applicationBenzene, toluene, ethyl acetate, etc. that are harmful to the human body and the environment must be used; in addition, some coatings have low adhesion intensity, the adhesio...

Problems solved by technology

[0002] With the improvement of people's living standards, people's pursuit of beauty is becoming more and more intense. Glass partitions, glass bathrooms, etc. need to use glass doors. However, with the continuous expansion of the application field, higher and higher requirements are put forward for the functional characteristics of glass coatings, which have far exceeded the requirements of traditional decoration and beautification. Since most of the current glass coatings are solvent-based coatings, the application It is necessary to use benzene, toluene, ethyl acetate and other benzene-containing solvents that are harmful to the human body and the environment; in addition, some coatings have low bonding strength, and the adhesion to various glass products is small, easy to fall off, and the use time is not long
