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 liquid crystal polymer compound for electroplated decoration. The liquid crystal polymer compound comprises the following raw materials in percentage by weight: 40-90% of liquid crystal polymer, 3-20% of thermoplastic elastomer, 0-30% of polyamide resin, 0-40% of inorganic ore powder and 0-2% of coupling agent, wherein the melt index of the thermoplastic elastomer is higher than that of the liquid crystal polymer. The invention also provides a preparation method of the liquid crystal polymer material for electroplated decoration. The liquid crystal polymer material provided by the invention can satisfy electroplating requirements, and can be treated by an environment-friendly potassium permanganate roughening solution, thereby conforming to the development of environment-friendly electroplating; after electroplating, the electroplating binding force between the material and the surface of an electroplating coating layer can be up to 10N or above, thereby ensuring the use safety; and meanwhile, the liquid crystal polymer material has excellent mechanical properties.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a liquid crystal polymer material used for environmental protection electroplating and a preparation method thereof. Background technique [0002] Plastic electroplating can make the surface of plastic products have a metallic luster, which is beautiful, plays a decorative role, improves the mechanical strength of the product surface, and prolongs the service life; makes plastic products have high stability against external factors such as light and atmosphere, and is not easy to age; Plastics are electrically conductive, magnetically conductive and weldable.
