Abstract

The invention discloses a thermally conductive and insulating corrosion-resisting modified plastic. The modified plastic comprises the following components in parts by weight: 30-60 parts of chlorinated polyethylene, 5-15 parts of polytetrafluoroethylene, 10-25 parts of polypropylene, 2-5 parts of maleic anhydride grafted polyethylene, 1-3 parts of zine stearate, 0.1-1 part of liquid paraffin, 1-5 parts of a silane coupling agent, 1-4 parts of nano silica, 3-12 parts of heat-conduction aluminium oxide powder, 1-2 parts of nano zinc oxide, and 0.01-0.5 parts of an anti-oxidant PS802. The produced plastic has good heat-conduction insulating function; the added maleic anhydride grafted polyethylene promotes compatibility of a plastic substrate, and the stretch-proofing performance, corrosion resisting performance, uv-shielding capacity and service life of the plastic product are increased.
