Description

technical field [0001] The invention relates to a plastic, in particular to a high-strength heat-conducting plastic and a preparation method thereof. Background technique [0002] The main components of thermally conductive plastics include matrix materials and fillers. Matrix materials include PPS, PA6 / PA66, LCP, TPE, PC, PP, PPA, PEEK, etc.; fillers include AlN, SiC, Al2O3, graphite, fibrous high thermal conductivity carbon powder, flake high thermal conductivity carbon powder, etc. Thermally conductive plastics use thermally conductive fillers to evenly fill polymer matrix materials to improve their thermal conductivity. The quality of thermal conductivity is mainly measured by thermal conductivity (unit: W / m·k). Cocoa is better used in the fields of LED lighting, automotive, heating / cooling / refrigeration technology. However, ordinary thermally conductive plastics have the disadvantages of poor impact resistance and low strength. Contents of the invention [0003] T...
