Problems solved by technology

Among them, compared with the single-component water-based paint, although the two-component water-based paint can improve the delamination phenomenon with the oily primer to a certain extent, it still cannot effectively solve the delamination problem of the oil base and water surface.
Moreover, because harmful substances such as solvents in the curing agent of the two-component water-based topcoat are easily volatilized into the environment, affecting the health of builders and consumers, there are potential safety hazards
In addition, during the painting process, the two-component water-based topcoat also has a limit on the usable time

Abstract

The invention provides a high-adhesion water-based paint suitable for various substrates and a preparation method thereof. The water-based paint consists of the following raw materials in parts by weight: 70-90 parts of self-crosslinking water-based acrylic resin, 1-10 parts of composite wetting leveling agent, 0-3.5 parts of extinction powder, 0.1-0.5 part of pH regulator, 4-8 parts of cosolvent,0.2-0.8 part of defoamer, 0.4-3 part of thickener and 4-10 parts of water. The self-crosslinking water-based acrylic resin contains at least two functional groups of hydroxyl, carboxyl, epoxy group and acylamino; the composite wetting leveling agent is composed of a wetting leveling agent A and a wetting leveling agent B according to a mass ratio of 1: 0.5-2. The wetting leveling agent A is an alkynediol nonionic surfactant; and the wetting leveling agent B is polyether siloxane. The water-based paint is suitable for substrates made of various materials such as PU and metal, can effectively solve the delaminating problem of the substrates and oily primer, and is good in adhesive force, safe, environmentally friendly and high in operability.

Description

technical field [0001] The invention relates to the technical field of water-based coatings, in particular to a high-adhesion water-based coating suitable for various substrates and a manufacturing method thereof. Background technique [0002] Coating paint films on furniture substrates of various materials can not only greatly improve the feel and appearance, but also effectively improve the product's scratch resistance and chemical resistance. Therefore, coatings are widely used on furniture substrates. In recent years, under the influence of consumers' environmental protection awareness and relevant laws and regulations, many furniture factories have carried out equipment upgrading and process improvement in the promotion of environmental protection coating, and the coating products have also been optimized accordingly. [0003] Among them, many furniture factories have improved the oil-to-water process, but the sealing performance of water-based coatings on the substrate...
