Abstract

The invention discloses a water-based coating varnish for door industry, which is prepared from the following components in percentage by mass: 60 to 80 percent of water-based resin, 6 to 12 percent of amino resin, 1 to 5 percent of flowing deformation modification assistant, 0.1 to 1 percent of wetting dispersing assistant, 2 to 6 percent of cosolvent, 8 to 20 percent of deionized water, 0.1 to 0.5 percent of antifoaming agent, 0.2 to 1.0 percent of pH regulation agent and 0.2 to 1.0 percent of flatting agent. The water-based coating varnish for door industry disclosed by the invention has the advantages of being single-component water-based stoving varnish, having no organic solvent such as benzene, toluene, xylene and the like and heavy metals, being non-flammable and non-explosive, andbelonging to environment-friendly products; the adhesive force is good, and the hardness is high; the varnish film is rich, and has high gloss; the construction performance is great and the construction requirements of door industry production can be met; the VOC (volatile organic compounds) is extremely low, and can be completely diluted by water; the product has the advantages of high performance, low cost and low pollution.

Description

technical field [0001] The invention relates to a water-based baking varnish in the technical field of paint making, in particular to a water-based baking varnish with good adhesion, high hardness, plump paint film, high gloss and excellent construction performance, which is mainly used for surface finishing of metal parts such as iron doors and anti-theft doors. Water-based finish varnish for decorative doors. Background technique [0002] In recent years, the anti-theft door production industry has grown rapidly with the rise of the real estate market, which has also led to the development of anti-theft door coatings. Baking varnish has always occupied a large share in the field of anti-theft door coating because of its convenient and fast construction and excellent coating performance, which can meet the requirements of various occasions. With the pressure of environmental protection policies, consumers' awareness of environmental protection continues to increase. In par...
