Description

technical field [0001] The invention relates to an alloy-type conductive plastic, which belongs to the technical field of plastics. Background technique [0002] Plastic is one of the most familiar materials. It has good strength, low density and corrosion resistance. It can be made into various mechanical parts and daily necessities. At the same time, it is also a widely used electrical insulating material. However, the winners of the Nobel Prize in Chemistry in 2000, American scientists Alan Haig, Alan Mark Diarmid and Japanese scientist Hideki Shirakawa found that after After special modification, the plastic can conduct electricity like metal. Conductive plastics not only have rapid development in antistatic additives, computer anti-electromagnetic screens and smart windows, but also have broad application prospects in light-emitting diodes, solar cells, mobile phones, miniature TV screens, and even life science research. In addition, the combination of conductive plas...

Problems solved by technology

Most of the existing composite conductive plastics are made of metal fiber, metal powder or carbon fiber mixed with various engineering plastic resins such as ABS, polycarbonate, polyester, polysulfone, etc., and filled with metal fiber or carbon fiber The filling amount of conductive material in the conductive plastic is small, so it has little effect on the mechanical properties of the material; and the electrical conductivity is good, but during the processing and molding process, due to the mechanical movement of the plastic molding equipment, the metal fiber or carbon fiber is seriously damaged. The electrical conductivity of the product is greatly reduced; therefore, the requirements for molding processing technology are harsh, and the electrical conductivity of the product is unstable. In fact, it is difficult to make the electrical conductivity of the product reach the best value.
