Abstract

The invention discloses a UV (Ultraviolent) deglossing paint and a preparation method thereof. The deglossing paint contains the following components by weight percent: 10 to 20% of UV resin, 3 to 8 % of light initiator, 15 to 25% of UV monomer, 5 to 20% of deglossing powder or deglossing slurry, 30 to 55% of solvent, 0.3 to 1% of dispersing agent and 0.4 to 1% of organosilicon leveling agent. The method comprises the following steps of: dispersing the light initiator, the dispersing agent and the organosilicon auxiliary into the solvent in advance, then adding the deglossing powder or the deglossing slurry, uniformly dispersing the solvent added with the deglossing powder or deglossing slurry to the fineness smaller than 25 mum, and finally adding and uniformly dispersing the UV resin and the UV monomer. In the formula provided by the invention, the hardness and brittleness of a paint film are regulated by controlling the type and amount of the UV monomer and the UV resin, and the paint film has good hardness and becomes brittle hardly. According to the invention, the solvent and the dispersing agent are firstly used to disperse the deglossing powder uniformly, thus avoiding the interaction of the deglossing powder and resin components; and since the deglossing powder is uniformly distributed in the paint film, the paint film is basically free from the floating phenomenon.

Description

technical field [0001] The invention relates to a paint, in particular to a UV matting paint and a preparation method thereof. Background technique [0002] UV is the abbreviation of Ultraviolet (ultraviolet), and UV paint is ultraviolet curing paint. UV-curable coatings have the advantages of long construction time, high production efficiency, and low environmental pressure. With the increasing application of modern plastic materials, UV coatings do not require high-temperature baking to make them more and more used. UV matting paint can endow the substrate with soft luster, delicate hand feeling, and endow the product with high-grade quality. The common problem of UV matting paint is that the gloss is not uniform, and it is prone to blooming, which affects the quality and grade of the product. [0003] The paint is sprayed on the substrate, and it will produce Bernard vortex after baking and curing. When the paint film is dry, the solvent evaporates on the surface of th...
