Environmentally friendly high-performance water-based audio paint

Abstract

The invention discloses an environment-friendly high-performance water-based paint for sound equipment, which is prepared from the following raw materials in percentage by weight: 60-75% of self-crosslinked core-shell polyurethane-fluorine acrylic acid hybrid resin, 0.1-0.3% of leveling agent, 0.3-0.5% of wetting agent, 0.2-0.3% of defoaming agent, 2-3% of dispersing agent, 5-8% of titanium white, 5-9% of barium sulfate, 0.1-0.2% of performance additive, 1.5-3% of thickener and the balance of deionized water. By compounding the self-crosslinked core-shell polyurethane-fluorine acrylic acid hybrid resin with the thickener, leveling agent, wetting agent and other assistants, the prepared environment-friendly high-performance water-based paint for sound equipment has the comprehensive properties of high hardness, scratch resistance, high fullness, plump and smooth spray points and the like. By using the water as the solvent, the environment-friendly high-performance water-based paint for sound equipment is pollution-free and nontoxic for the environment and human body, is a novel environment-friendly material for coating sound equipment, and can be completely substituted for the existing oil-based paint for sound equipment.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an environment-friendly and high-performance water-based acoustic paint. Background technique [0002] The traditional oil-based speaker paint is a paint with aromatic hydrocarbons and their derivatives as solvents, which not only pollutes the surrounding environment, but also causes great harm to the human body. Therefore, with the continuous enhancement of people's awareness of environmental protection, it is imperative to find an excellent performance and environment-friendly paint to replace the traditional oil-based acoustic paint. [0003] Water-based paint is a paint with water as a solvent, which greatly reduces the emission of VOC. At present, many water-based paints can achieve zero VOC emission, which greatly alleviates the current environmental pollution problem in the coating industry. [0004] Water-based speaker paint is one of the sub-applications of water-based...

Problems solved by technology

However, the performance of general water-based speaker paints is worse than that of oil-based paints, especially in terms of hardness, fullness and gloss, which do not meet specific requirements, which limits the application of water-based speaker paints
