Appearance-improving spraying-free aesthetic resin and its preparation method

The invention relates to an appearance-improving spraying-free aesthetic resin and its preparation method. The resin comprises the following components by weight part: 90 of matrix resin, 0.1-2.0 of a lubricant, 0.1-1.0 of an antioxidant, and 10-30 of a magnetic metallic pigment masterbatch, which consists of the following components by weight part: 100 of the matrix resin, 1.0-20 of a magnetic metallic pigment, 1.0-30 of a pearlescent pigment, 0.1-2.0 of the lubricant, 0.1-1.0 of the antioxidant. The preparation method includes: preparing the magnetic metallic pigment masterbatch; and mixingthe above raw materials, then conducting mixing, extrusion, bracing, cooling, and pelletizing, thus obtaining the aesthetic resin. The aesthetic resin of the invention can effectively improve the affinity of an aluminum powder pigment and a plastic substrate, mitigate flow marks and weld lines that appear during injection molding or extrusion of aluminum powder pigment-containing aesthetic resin,and simultaneously strengthens the metal effect a made piece, greatly reduces consumption of the aluminum powder pigment, and saves cost. The present invention is green and environmental aesthetics resin instead of traditional paint scheme provides technical support. The aesthetic resin and the preparation method provided in the invention provide technical support for green and environmentally friendly aesthetic resin to substitute traditional paint spraying schemes.
