Problems solved by technology

[0004] The water-based sprinkler paint provided by the prior art has a natural shape, strong texture, smoothness, and fast drying. It can be rinsed with a topcoat in 60 minutes at a normal temperature of 25 ° C. The topcoat can be a two-component water-based wood paint. A coating film can be formed after drying for 12 hours. This water-based sprinkler paint is environmentally friendly and safe, and is suitable for the coating of large stage speakers and musical instruments; however, the water-based sprinkler paint provided by the prior art has low hardness and poor adhesion , which limits its wide application

Abstract

The invention provides a water-based dotting paint which comprises the following components in parts by weight: 15-30 parts of epoxy acrylate, 5-15 parts of reactive diluent (comprising trimethylolpropane triacrylate and neopentyl glycol diacrylate), 0-2 parts of dispersing agent, 1-4 parts of diphenyl ketone photoinitiator, 0-3 parts of polyurea thickener, 5-10 parts of alcohol compound, 0-8 parts of matting powder, 5-10 parts of water, 0.1-1 part of defoaming agent, 0.2-1 part of leveling agent, 0-2 parts of organobentonite, 0-3 parts of silica white and 30-40 parts of powder (comprising talcum powder and calcium carbonate). The water-based dotting paint has high hardness and favorable adhesive force by comprehensively controlling various components. Besides, the water-based dotting paint has favorable dotting effect and is environment-friendly.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based sprinkling paint. Background technique [0002] Sprinkling paint refers to the application of a kind of paint that looks like dripping drops on the surface of the product. This coating can protect the surface of the object and has a sense of art. It is often used for the finishing of instruments, equipment, and metal products. Sprinkle paint has beautiful exterior and strong decorativeness, which can conceal shallow mechanical scars and rough and uneven surface defects on the surface of the coated object. [0003] The Chinese patent with the application number 200810142154.9 provides a water-based wood sprinkling paint, in parts by weight, including 8-10 parts water; 2-4 parts film-forming aids; 0.2-0.4 parts wetting Dispersant; 0.4 to 0.8 parts of defoamer; 50 to 60 parts of filler; 10 to 30 parts of acrylic emulsion; 1 to 1.5 parts of thickener; preparation method of t...
