Problems solved by technology

[0003] Compared with spray paint materials, spray-free aesthetic resins have a lower overall cost, but they use more special-effect toners. Spray-free aesthetic resins contain special-effect toners as a whole, and only the surface layer of the resin determines the appearance of the parts. Toner, most of the toner inside the resin is wasted; on the other hand, in order to increase the effect of spray-free aesthetic resin, it is necessary to increase the amount of toner, which increases the flow of metallic pigments or pearlescent pigments. Defects such as flow marks and weld lines caused by different orientations limit the range of effects of spray-free aesthetic resins

Abstract

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.

Description

technical field [0001] The invention belongs to the field of resin formula and its preparation, and in particular relates to a spray-free aesthetic resin with improved appearance and a preparation method thereof. Background technique [0002] With the promotion of the concept of low-carbon environmental protection, the spray-free aesthetic resin that replaces spray paint has attracted more and more attention from many entrepreneurs and the public, showing unprecedented market competitiveness. Not only can it achieve the bright and colorful hues produced by spray paint and special effects such as pearlescent, flashing effects, and metallic colors, but it can also achieve semi-transparent, full-transparent and astigmatism effects that metals cannot achieve. Common plastics that can be used to prepare aesthetic resins include PP, ABS, PMMA, ABS / PMMA, PC, PC / ABS, ASA, polyester, PS, etc. Aesthetic resin not only has high production efficiency and low cost, but also can be recyc...
