Abstract

The invention discloses a PC/ABS (Acrylonitrile Butadiene Styrene) composite material with faint scent smell and an imitated flocking effect and a preparation method thereof. The PC/ABS composite material is mainly composed of 10-20 parts of a modified green tea powder functional master batch, 0-40 parts of ABS resins, 38-83 parts of PC resins, 5-10 parts of a compatilizer and 2-5 parts of an antioxidant and other additives. By performing surface passivation modification on natural green tea powder, the compatibility of the green tea powder and the PC/ABS resins is effectively improved, so that the prepared PC/ABS composite material has excellent mechanical property. Meanwhile, since the green tea powder has faint scent smell of the natural green tea, parts prepared by the composite material have faint scent smell of the green tea. In addition, since the dark-green green tea powder serves as a filling agent, many dark color spots appear on the surfaces of cream-colored or gray parts and other light color parts prepared by performing color matching treatment on the prepared composite material. The composite material has a similar flocking effect.

Description

technical field [0001] The invention relates to a functional PC alloy material and a preparation method thereof, in particular to a PC / ABS functional masterbatch with a delicate smell and a flocking effect and a preparation method thereof, belonging to the technical field of PC. Background technique [0002] PC / ABS alloy materials have excellent mechanical properties and high strength, and are widely used in many fields such as automotive interiors and home appliances. However, conventional PC / ABS materials will release various harmful substances to varying degrees due to thermal degradation of macromolecular segments after high-temperature melt extrusion processing, which affects their application in related fields, especially in the field of automotive interior materials. At present, in terms of improving the odor of polyester materials, relevant experts and scholars at home and abroad have done some research, mainly by reducing the residual monomer and oligomer content of...
