Problems solved by technology

The traditional PC / ABS material with metallic texture is realized by spraying the primer first, and then spraying the metal topcoat. Since the primer is a thermosetting material, it is difficult to melt again, and the plastic products after painting have poor recycling performance, which will affect their reuse. The process is cumbersome and pollutes the environment, the waste rate is high, and toxic and harmful gases and dust are produced, which seriously endanger human health, and also cause environmental pollution and energy waste.
In addition, due to the influence of polymerization process, catalyst, oxide residue and short-chain oligomers, PC and ABS materials will release harmful volatile organic compounds (VOC) to varying degrees during high-temperature processing and use.
At the same time, limited by its own performance, most of its strength, stability, processability, and functionality cannot meet the requirements of use, and cannot be directly used to produce plastic products.
At present, it is generally used to improve its performance by adding functional additives, and commonly used functional additives, such as flame retardants, tougheners, coupling agents, lubricants, stabilizers and other materials, may bring some harmful VOC , and the smell is abnormal, which is extremely unfavorable to people who use such materials in a relatively closed environment, and seriously endangers the environment and health

Abstract

The invention discloses a PC / ABS composite material of a metal texture. The composite material is prepared from the following components in parts by weight: 65-98 parts of resin, 0-2 parts of pearl resin, 0.05-0.1 part of silicone oil, 0.5-5 parts of a metal pigment, 0.5-1.5 parts of an extractant, 0.5-1 part of an adsorbent, 0.2-1 part of a processing heat stabilizer, 0.1-2 parts of a processinglubricant and 0.5-25 part of other functional auxiliary agents. The resin is a mixture of polycarbonate and ABS resin in a proportion of 1: 1. The composite material is high in strength, good in stability, high in processibility, high in metal texture and high in interfacial strength, does not drop powder, and is free of harmful volatile organic compounds, so that the problem of environmental pollution caused by follow-up processing is avoided, and the composite material is more environment-friendly and safe.

Description

technical field [0001] The invention relates to the technical field of organic polymer materials, in particular to a metal textured PC / ABS composite material and a preparation method thereof. Background technique [0002] With the development of society, people's requirements for beauty are getting higher and higher, and the application of metal textured PC / ABS materials is becoming more and more extensive. The traditional PC / ABS material with metallic texture is realized by spraying the primer first, and then spraying the metal topcoat. Since the primer is a thermosetting material, it is difficult to melt again, and the plastic products after painting have poor recycling performance, which will affect their reuse. The process is cumbersome and pollutes the environment, the waste rate is high, and toxic and harmful gases and dust are produced, which seriously endanger human health, and also cause environmental pollution and energy waste. In addition, due to the influence of...
