Abstract

The invention discloses a PC and PE composite antibacterial plastic alloy. The PC and PE composite antibacterial plastic alloy comprises following ingredients, by weight, 100 portions of PC, 10 to 20 portions of PE, 3 to 5 portions of SEBS-g-MAH and 0.6 to 0.8 portion of an antibacterial agent. Antibacterial effect of the PC and PE composite antibacterial plastic alloy is excellent.

Description

technical field [0001] The invention relates to a plastic alloy, in particular to an antibacterial plastic alloy composed of PC and PE. Background technique [0002] PC, polycarbonate, is a polymer with carbonate groups in its molecular chain. Due to the special structure of polycarbonate, it has become the fastest-growing general-purpose engineering plastic among the five major engineering plastics. [0003] PE, polyethylene, is a thermoplastic resin obtained by polymerization of ethylene. Polyethylene has good chemical stability, can withstand the erosion of most acids and alkalis, is insoluble in common solvents at room temperature, has low water absorption, and has excellent electrical insulation properties. [0004] However, the antibacterial properties of the current PC and PE composite plastic alloys are not good. Contents of the invention [0005] Aiming at the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present inven...
