Abstract

The present application relates to the technical field of nylon composite material, in particular to a plating-resistant high-temperature nylon composite material and a preparation method thereof, which takes PA6T / 66 copolymer as the main material, has high high-temperature resistance and toughness, and has the synergistic effect of MXD6-G-MAH, chain extender, carbon nanotube and ionic polymer resin, so that the surface can better interact with metal ions in the plating solution, promote the reduction and deposition of metal ions on the surface, form a dense and firm plating layer, and be conducive to obtaining a metal plating layer with higher stability after plating of the plating-resistant high-temperature nylon composite material. In addition, the addition of toughening agent and glass fiber further improves the material strength on the basis of A6T / 66 copolymer; the addition of halogen-free flame retardant and synergistic flame retardant further improves the high-temperature resistance of the material. The plating-resistant high-temperature nylon composite material has high high-temperature resistance and toughness as a whole, and has good plating layer stability after plating, meeting the requirements of SMT process on the high-temperature resistance, toughness and plating layer stability of components.
