Abstract

The invention discloses an aqueous woodware solid color paint and a preparation method thereof, wherein the raw materials comprise, by weight, 1.00-10.00% of pure water, 1.00-3.00% of a pigment regulating agent, 20.00-40.00% of a filler, 40.00-70.00% of an emulsion A, 1.00-6.00% of a film forming aid, 0.10-0.50% of a substrate wetting agent, 0.10-0.50% of a defoamer, and 0.10-0.50% of a rheological auxiliary agent. According to the present invention, by using the self-cross-linking core-shell double-technology emulsion as the main raw material, the aqueous woodware solid color paint has good wettability on wood plates, and has high bonding degree with wood in the application in coating materials; and due to the unique structure design, the double-technology acrylic emulsion has good film forming performance, such that the paint film and the solvent type primer coat are densely combined so as to achieve good adhesion.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based wood solid color paint and a preparation method thereof. Background technique [0002] With the increasing awareness of environmental protection in the whole society, water-based coatings have accounted for most of the total coatings in my country. Water-based paint is a kind of paint made by grinding water-based synthetic resin as the main film-forming substance, water as diluent, adding appropriate amount of pigments, fillers and auxiliary materials, etc. It can be called water-based paint or water-based paint. [0003] In recent years, with the pressure of environmental protection policies, consumers' awareness of environmental protection has been continuously improved; in particular, provinces and cities across the country have introduced VOC emission limit standards to encourage the use of non-solvent-based coatings, which has brought new opportunities to the...
