Abstract

The invention discloses an IMD (In-Mole Decoration) injection molding PC / ABS (Polycarbonate / Acrylonitrile Butadiene Styrene) composite material and a preparation method. The IMD injection molding PC / ABS composite material comprises the following components in parts by weight: 50-70 parts of PC, 6-10 parts of ABS terpolymer, 6-18 parts of filler, 3-8 parts of toughening agent, 10-13 parts of flame retardant, 0.2-0.8 part of anti-dripping agent, 0.1-0.5 part of antioxidant, 0.1-0.5 part of lubricating agent, 1-2 parts of dispersing agent and 1-3 parts of ductility improver. In the invention, the PC and the ABS terpolymer are used as base materials, and blending modification is carried out by filling minerals and combining the toughening agent, the flame retardant, the antioxidant, the lubricating agent, the dispersing agent and the ductility improver. Compared with traditional PC / ABS alloy, the composite material maintains the physical properties of the traditional PC / ABS material and also greatly improves the size stability of the traditional PC / ABS alloy material, thereby solving the problem of buckling deformation of secondary stamping of the traditional PC / ABS in IMD injection molding.

Description

[technical field] [0001] The invention relates to the technical field of polymer materials, in particular to an IMD injection-molded PC / ABS composite material and a preparation method thereof. [Background technique] [0002] IMD-in-mold decoration technology is a popular surface decoration technology in the world at present. The surface is hardened and transparent film, and the pattern layer is printed in the middle, which can prevent the surface of the product from being scratched and rubbed, and can keep the color bright and not easy to fade for a long time. [0003] IMD-in-mold decoration is a relatively new automated production process. Compared with other processes, it can reduce production steps and reduce disassembly components, which can save time and cost. It also has the advantages of improving quality, increasing image complexity and The advantage of improving the durability of the product is applied to the appearance of the product, which is currently the most ef...
