Problems solved by technology

The main problem in spraying is highly dispersed paint mist and volatilized solvents (i.e. volatile organic pollutants, VOCs), which not only pollute the environment, are not conducive to human health, but also waste baking paint, causing economic losses

Abstract

The invention provides a high-wear-resistance high-adhesive-force modified epoxy amino baking varnish and a preparation method thereof. The baking varnish comprises an organosilicon-modified epoxy resin, a polyethyleneglycol-modified amino resin, a cellulosic resin, polydimethylsiloxane, deionized water, nano tin oxide, a titanate coupling agent, isopropanol, a water-based monomer, a pH neutralizer, a cosolvent, a wetting and dispersing agent, a defoamer, a thickener, an emulsifier, and a pigment and filler. By using the organosilicon-modified epoxy resin and polyethyleneglycol-modified amino resin as the main components of the epoxy amino baking varnish, the modified epoxy resin and amino resin can effectively enhance the hardness of the paint film. The composition design is reasonable; the deionized water is used as the solvent for dilution, and thus, is environment-friendly; the baking varnish has the advantages of higher wear resistance, high wear resistance, favorable ductility, high-temperature resistance and long service life; and roller coating is used instead of spray coating, thereby effectively improving the production environment and being beneficial to good health of workers.

Description

technical field [0001] The invention relates to a modified epoxy amino baking varnish with high wear resistance and strong adhesion and a preparation method thereof. Background technique [0002] Baking varnish is divided into two categories, one is low-temperature baking varnish with a curing temperature of 140°C-180°C, and the other is called high-temperature baking varnish with a curing temperature of 280°C-400°C. [1] High-temperature baking varnish, the English full name is Polytetrafluoroetylene, referred to as Teflon, PTFE, F4, etc. Teflon high-performance special baking varnish is a fluorine baking varnish based on polytetrafluoroethylene. The English name is Teflon. Because of the pronunciation, it is usually called Teflon, Teflon, Teflon, Teflon Long and so on (all are transliterations of Teflon). [0003] According to the different main components, baking varnish can be divided into polyester amino baking varnish, alkyd amino baking varnish, acrylic amino baking ...
