Water-based acrylic amino stoving varnish

Abstract

The invention discloses a water-based acrylic amino stoving varnish which comprises the following materials in weight percentage: 50-60% of water-soluble acrylic resin, 10-15% of full methylated amino resin, 0.4-0.6% of an epoxy group silane coupling agent, 15-25% of a pigment, and the balance of water. The water-based acrylic amino stoving varnish uses the water-soluble acrylic resin as a film forming agent and the full methylated amino resin as a coupling agent, as the water-soluble acrylic resin and the full methylated amino resin have a hydrophilic group and can be directly dissolved in water, then no residual emulgators exist after the water-based acrylic amino stoving varnish is dried and solidified, and the water resisting property of the water-based acrylic amino stoving varnish is greatly improved. The water-based acrylic amino stoving varnish adopts the epoxy group silane coupling agent, then the pigment is excellent in compatibility with the film forming agent and the coupling agent, and the service life of the water-based acrylic amino stoving varnish is prolonged. The drying and solidifying speeds of the water-based acrylic amino stoving varnish are high, and the required drying temperature is low.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based acrylic amino baking varnish. Background technique [0002] With the continuous improvement of people's awareness of environmental protection and the increasingly stringent environmental regulations, environmentally friendly coatings will become the protagonists of the world coatings market in the 21st century. Due to the high content of organic solvents in solvent-based coatings, it is easy to cause harm to people and the environment during construction and application. It is urgent to transform the coatings industry into a "green industry". As a product of paint, water-based paint has water as its solvent, and there is no hidden danger of flammability and explosion. It has become one of the main directions of paint development because of its safety, non-toxicity, resource conservation, and environmental protection. Water-based paint is an important part of the pa...

AI Technical Summary

Problems solved by technology

[0003] There are a lot of emulsifiers in the paint film formed by traditional water-based acrylic emulsion and amino resin baking and cross-linking, and the film-forming density of latex particles is not high, resulting in poor water resistance of the paint film after drying and curing
