Problems solved by technology

[0003] Compared with spray painting of plastic parts, the overall cost of spray-free aesthetic resin has certain advantages in one-time molding, but the spray-free aesthetic resin contains special-effect toner as a whole, and only the toner on the surface of the resin determines the appearance of the part, most of which are in the resin. The internal toner does not contribute to the appearance of the part; on the other hand, in order to increase the effect of spray-free aesthetic resin, it is necessary to increase the amount of special effect toner, which will aggravate the flow disorder caused by metallic pigments or pearlescent pigments. Defects such as flow marks and weld lines limit the range of effects of spray-free aesthetic resins

Abstract

The invention relates to a spraying-free aesthetic resin composition with magnetism. The resin comprises the following components in parts by weight: 70-90 parts of matrix resin, 0.1-2.0 parts of lubricant, 0.1-1.0 part of antioxidant and 10-30 parts of magnetic metallic pigment master batch. The magnetic metallic pigment master batch comprises the following components in parts by weight: 100 parts of matrix resin, 1.0-20 parts of magnetic metallic pigment, 1.0-30 parts of pearlescent pigment, 1.0-2.0 parts of lubricant and 0.1-0.3 parts of antioxidant. The preparation method comprises the steps of preparing the magnetic metallic pigment master batch; agitating and mixing the raw materials, extruding, drawing into bars, cooling and cutting into grains to obtain the spraying-free aesthetic resin composition. The spraying-free aesthetic resin composition with magnetism has the advantages that the flow marks and the weld lines occurring in the injection molding or extrusion process of the aesthetic resin containing aluminum powder pigment are effectively reduced, the metal effect of produced parts is enhanced at the same time, the amount of the used aluminum powder pigment is reduced and the cost is saved.

Description

technical field [0001] The invention belongs to the field of resin formulation and its preparation, in particular to a magnetic spray-free aesthetic resin composition and a preparation method thereof. Background technique [0002] Spray-free aesthetic resin is one of the latest products in the field of engineering plastics. Its low-carbon environmental protection, one-time molding and colorful special effects are more and more popular among people. Spray-free aesthetic resins can not only reproduce the bright and colorful hues produced by spray paint and special effects such as pearlescent, flashing effects, and metallic colors, but 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 recycled, and is widely used ...
