Abstract

The invention relates to the field of a plastic cement novel material, in particular to a PPS composite material for nanometer injection molding and a preparation process thereof. The PPS composite material for nanometer injection molding is prepared from the following ingredients in parts by weight: 50 to 80 parts of resin, 5 to 35 parts of continuous long carbon fiber, 2 to 10 parts of silicon dioxide, 3 to 8 parts of tougheners, 0.5 to 1 part of antioxidizers, 0.5 to 2 parts of coupling agents and 0.5 to 1 parts of lubricating agents. The toughener is maleic anhydride grafted styrene-ethylene-butadiene-styrene; the laser additive is nanometer copper powder modified by acrylic ester. The PPS composite material for nanometer injection molding has the advantages of good mechanical performance, high bonding force with metal materials and good heat resistance, so that the NMT (nano molding technology) process requirements can be better met.

Description

technical field [0001] The invention relates to the field of new plastic materials, in particular to a PPS composite material for nano-injection molding and a preparation process thereof. Background technique [0002] Nano injection molding (Nano Molding Technology, NMT) is a process method that combines metal and plastic with nanotechnology. Firstly, the metal surface is formed with nano-micropores, and the plastic is directly injected onto the metal surface, so that the metal and plastic can be integrally formed, which not only takes into account the appearance and texture of the metal, but also simplifies the design of the product mechanism, making the product lighter, thinner, shorter and smaller , and is more cost-effective than the CNC method; at the same time, because NMT is a safe and recyclable technology, it has little impact on the environment. [0003] At present, the metal materials that can be used for NMT forming are mainly concentrated on aluminum and magnes...
