Polyamide compound for environment-friendly electroplating and preparation method thereof

Abstract

The invention provides a polyamide compound for environment-friendly electroplating. The polyamide compound is prepared from the following raw materials in percentage by weight: 40 percent to 90 percent of aromatic-ring-containing polyamide resin, 3 percent to 20 percent of a thermoplastic elastomer, 0 percent to 20 percent of aliphatic polyamide, 0 percent to 2 percent of a coupling agent and 0 percent to 40 percent of inorganic ore powder, wherein the melt index of the thermoplastic elastomer is higher than that of the aromatic-ring-containing polyamide resin and the aliphatic polyamide. Theinvention further provides a preparation method of the polyamide compound for the environment-friendly electroplating; the polyamide compound provided by the invention has better electroplating performance and mechanical property and can be treated by utilizing an environment-friendly potassium permanganate roughening solution, so that the polyamide compound is suitable for the development of theenvironment-friendly electroplating; after the electroplating is carried out, the electroplating binding force between the polyamide compound and the surface of an electroplating cladded layer can reach 10N or more; the utilization safety is ensured.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a polyamide compound 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. Plastic electroplating products can be used in industries such as aerospace, shipbuilding, automobiles, electronic appliances, architectural decoration, toys and daily necessities, and have a wide range of uses. [0003] There are two common electroplating processes for plastic products: water electroplating and va...

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, its market application is not as broad as that of ABS
