Problems solved by technology

Hexavalent chromium is an ingestion poison / inhalation poison, and skin contact may cause allergies; it is more likely to cause genetic defects, inhalation may cause cancer, and has a persistent danger to the environment
The major defects of existing electroplating grade nylon materials are: 1. Need to use special nylon electroplating potion; 2. The bonding force of substrate electroplating is not high, which cannot meet the adhesion requirements of metal electroplating products; 3. The production is not flexible, High cost, the cost of traditional nylon electroplating process is about 2.4 yuan / DM, while the cost of ABS electroplating process is about 1.2 yuan / dm
Therefore, the market application is not as broad as ABS

Abstract

The invention provides a polyphenylene sulfide compound for environment-friendly electroplating. The compound comprises, by weight, 40-90% of polyphenylene sulfide resin, 3-20% of thermoplastic elastomer, 0-30% of polyamide resin, 0-40% of inorganic mineral powder and 0-2% of coupling agent, wherein melt index of the thermoplastic elastomer is higher than that of the polyamide resin and the polyphenylene sulfide resin. The invention further provides a preparation method of the compound. The polyphenylene sulfide compound is excellent in processing performance and mechanical performance, can be treated by using environment-friendly potassium permanganate roughing liquid and is suitable for development of environment-friendly electroplating; after electroplating, electroplating binding force with the surface of an electroplating coating reaches higher than 10N, and safety in use is guaranteed.

Description

Technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyphenylene sulfide compound used for environmental protection electroplating and a preparation method thereof. Background technique [0002] Plastic electroplating can make the surface of plastic products have metallic luster, beautiful appearance, play a decorative role, improve the mechanical strength of the surface of the products, and extend the service life; make the plastic products have higher stability to external factors such as light and atmosphere, and are not easy to age; Plastic is conductive, magnetic, and weldable.
