Description

technical field [0001] The invention relates to the field of material technology, in particular to a flame-retardant nylon / polyphenylene sulfide alloy material and its preparation method and application. Background technique [0002] Thermally conductive plastics have the high thermal conductivity of metals and ceramics, while retaining the advantages of ordinary plastics in design, performance and cost, and are widely used in the LED lighting industry. With the increasing power of LED lighting fixtures, heat dissipation has become an important factor affecting their service life. It is urgent to develop thermally conductive polymer materials with high reliability and excellent thermal conductivity. [0003] In order to meet the safety requirements for the use of LED lighting fixtures, it is generally required that the flame retardant level of the plastic shell material reaches the UL94v-0 level. At present, the usual practice is to add flame retardants such as brominated fl...
