Abstract

The invention discloses a preparation method of waterborne acrylic coating for woodenware. The preparation method comprises the following steps: uniformly stirring waterborne acrylic emulsion, composite microspheres, a waterborne de-foaming agent, a film-forming axillary agent, an anti-freezing agent and a waterborne wetting leveling agent to obtain pre-treated waterborne acrylic emulsion; uniformly stirring diatomite, fly ash, vermiculite powder and water; adding the pre-treated waterborne acrylic emulsion, a waterborne preservative and a waterborne thickener and continually stirring to obtain the waterborne acrylic coating for the woodenware. According to the preparation method of the waterborne acrylic coating for the woodenware, provided by the invention, the preparation method is simple; the obtained coating has excellent curing performance, great coating film thickness, excellent adhesive force and extremely high salt water resistance; meanwhile, a coating film sagging phenomenonis overcome and the service life is long.

Description

technical field [0001] The invention relates to the technical field of water-based paint, in particular to a preparation method of water-based acrylic paint for woodware. Background technique [0002] Wood coatings are an important part of the coatings industry. They refer to coatings used for equipment prepared from raw materials such as solid wood boards, wood grain panels, bakelite boards, and fiberboards. They are mainly suitable for furniture, building decoration materials, etc. [0003] At present, water-based acrylic coatings that combine high performance and low VOC content have become one of the fastest-growing coating varieties. Widely used in the wooden door coating industry, but water-based acrylic coatings still have technical problems of poor adhesion and salt water resistance, which limits their use in extreme environments. Contents of the invention [0004] Based on the technical problems existing in the background technology, the present invention propose...
