High-gloss spraying-free ABS (acrylonitrile butadiene styrene) composite material with special effect and preparation method thereof

Abstract

The invention relates to the technical field of polymer materials, in particular to a high-gloss spraying-free ABS (acrylonitrile butadiene styrene) composite material with special effect and a preparation method thereof. The composite material comprises, by weight: 70-90 parts of ABS resin, 4.0-10 parts of a compatilizer, 5.0-10 parts of a toughener, 1.0-3.0 parts of white oil, 0.4-0.6 part of a composite antioxidant, 0.5-1.0 part of a lubricant, and 1.0-5 parts of pearl powder. The preparation method is simple, and the prepared ABS composite material has good mechanical properties, low aid emigration rate, significant pearl effect, smooth surface free of flow marks and scratch resistant, and long service life.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-gloss spray-free ABS composite material with special effects and a preparation method thereof. Background technique [0002] As people pay more and more attention to environmental issues, countries around the world have introduced strict environmental protection regulations for home appliances and other major environments, coupled with the embodiment of corporate social responsibility, spray-free material products are gradually showing their competitiveness, spray-free aesthetics Resin can reproduce the bright and colorful hues produced by spray paint and special effects such as pearlescent, glittering, metallic luster and texture, so as to meet the needs of customers whose product design trends are differentiation, personalization, diversification and differentiation, and in the production process It can really reduce the production process, improve the rate of ...

Problems solved by technology

Although this preparation method effectively solves the problem of flow marks that are easily produced when traditional aluminum powder pigments are introduced into the plastic matrix on the basis of maintaining a good metallic luster, the preparation of coated aluminum powder block pigments by double-roll mixing The method is complicated, new equipment needs to be added, and the investment is large. At the same time, the aluminum powder is easily broken and damaged by twin-screw shearing, which affects the metal effect.

[0005] Kingfa Science and Technology patent CN104629245A discloses a spray-free ABS composition with special aesthetic effects and its preparation method and application. In this patent, the special effect powder is coated with an aqueous polymer dispersion into microspheres and then dispersed into ABS resin , although the compatibility of special effect powder and ABS resin is obviously improved, the flow mark formed on the surface of the product during extrusion or injection molding is eliminated, and the weld line is lightened, but the special effect powder is coated with a water-based polymer dispersion into a micro The preparation process of the ball is complicated, which affects the production efficiency
