Problems solved by technology

[0007] Although there are many reports on water-based paint in current patents, there are few reports on the preparation of water-based relief paint and the spraying process of water-based relief paint. Due to the certain viscosity of water-based relief paint and the need for professional spraying equipment in the spraying process, these spraying equipment Not only is the cost high, but it is also very inconvenient to use, which severely limits the application of water-based relief paint spraying. Therefore, it is necessary to design a water-based relief paint with excellent performance, and to design a device that can realize automatic spraying of water-based relief paint

Abstract

The invention provides a water-based relief paint, which aims at overcoming the defects of the prior art. The water-based relief paint has the advantages that the anti-sagging property is excellent, the adhesion force and water-resistant property are good, the hardness is high, and the gloss is good. The water-based relief paint is prepared from the following components in parts by weight: 60 to 70 parts of water-based acrylic resin, 6 to 10 parts of water-based polyurethane, 0.3 to 1 part of dispersant, 0.3 to 0.6 part of wetting agent, 0.3 to 0.5 part of defoaming agent, 1 to 4 parts of anti-scratching agent, 1 to 5 parts of filming agent, 20 to 30 parts of filler, 2 to 4 parts of color paste, and 0.4 to 0.8 part of thickener. The invention also provides an automatic spraying device of the water-based relief paint. The automatic spraying device of the water-based relief paint has the advantages that the spraying of the water-based relief paint is simple, convenient and universal; inthe actual use process, dimethyl ether is used as propelling gas, so that the display effect of the water-based relief paint is more vivid.

Description

technical field [0001] The invention relates to the field of surface functional materials, in particular to a water-based embossing paint, a preparation method thereof, and an automatic spraying device for the water-based embossing paint. technical background [0002] Water-based paint is an environmentally friendly paint with water as the main solvent or dispersion medium, resin as the dispersed phase, and water as the continuous phase. It has the advantages of low VOC content, no odor, non-flammable and low toxicity. With the development of green coatings, water-based coatings are increasingly becoming the main force in the coatings market. Water-based coatings mainly include water-soluble coatings and water-dispersible coatings (latex paints). Water-soluble coatings use water-soluble resins as film-forming materials, represented by water-soluble alkyd resins, water-soluble epoxy resins, water-soluble polyurethane resins, electrophoretic coatings, and inorganic polymer wa...
