[0004] At present, plastic modification companies in Nanjing, Jiangsu, and Shanghai in the Yangtze River Delta have developed and produced flame-retardant nylon materials using red phosphorus as a flame retardant, such as PA66GF30FR flame-retardant materials, but the use of red phosphorus flame retardants is different from nylon Corrosion of the copper material connected by the material is usually carried out on the surface of the copper material in the prior art, but this cannot fundamentally solve the problem of copper corrosion

Abstract
The invention relates to a corrosion-resistant flame-retardant nylon material, and belongs to the technical field of plastic products. The corrosion-resistant flame-retardant nylon material comprises the following components in parts by weight: 35-65 parts of nylon resin, 5-20 parts of a red phosphorusfire retardant, 1.5-3.0 parts of a lubricant, 0-30 parts of a reinforcing agent, 0.2-1.0 parts of a precipitation inhibitor and 0.1-0.5 part of an antioxidant. The corrosion-resistant flame-retardant nylon material is obtained by mixing the components in a high-speed mixing machine, extruding the components in a screw extruder and then granulating. The corrosion-resistant flame-retardant nylon material can be prevented from corroding a copper material which is connected with the corrosion-resistant flame-retardant nylon material, is excellent in environmental protection and flame retardancy, good in electric performance and excellent in mechanical property, and can be widely applied to the field of electrical plastic parts such as electronic element connectors and the like.
Description
technical field [0001] The invention relates to the technical field of plastic products, more specifically, the invention relates to a corrosion-resistant and flame-retardant nylon material, especially a flame-retardant nylon material injection molded with copper products and its production method and application. Background technique [0002] Brominated flame retardants have a good flame retardant effect on plastic products, but brominated flame retardants may produce harmful substances when heated and decomposed, and they may also be released from materials and enter the ecological environment and food chain, which may be harmful to the human body. Hazardous to health and the environment. The European Union's RoHS Directive restricts the application of two brominated flame retardants, polybrominated biphenyls and polybrominated diphenyl ethers, in electronic appliances, and the United States has also banned the use of polybrominated biphenyls. China's "Electronic Informati...
