Abstract

The invention discloses an environment-friendly glass baking varnish. The glass baking varnish is prepared from the following raw materials in parts by weight: 45 to 65 parts of a water-soluble fluorine-containing selenocyano amino triazine resin, 15 to 25 parts of a cationic waterborne polyurethane, 2 to 5 parts of an enclosed cross-linking agent UN-7038, 1 to 5 parts of a leveling agent, 20 to 30 parts of deionized water, 3 to 7 parts of a pigment and 1 to 3 parts of an antifoaming agent. The invention also discloses a preparation method of the environment-friendly glass baking varnish. Theenvironment-friendly glass baking paint disclosed by the invention is good in dry and wet adhesion, excellent in alcohol resistance, water resistance and wear resistance, high in hardness, excellent in comprehensive performance, safe and environment-friendly in production and use processes, good in paint film weather resistance and long in service life.

Description

technical field [0001] The invention relates to the technical field of chemical coatings, in particular to an environment-friendly glass baking varnish and a preparation method thereof. Background technique [0002] With the development of the economy and the advancement of the global industrialization process, resource and environmental issues have become a pair of major contradictions in the sustainable development of today's society. The performance of the chemical coating industry is particularly prominent, and its price and quality market competition is becoming increasingly fierce. At the same time, VOC emissions will directly pose a serious threat to the environment and people's health. Therefore, the development of environmentally friendly chemical coatings has become an inevitable trend in the development of the chemical coatings industry. [0003] As a common material, glass and glass products are widely used and are closely related to people's lives. Cosmetic bo...
