Problems solved by technology

However, in some special fields, PE is required to have high hardness, good friction resistance and antibacterial properties, and PE alone cannot meet these requirements
[0003] In order to increase the scope of use of polyethylene and increase the hardness of polyethylene, the hardness of high-density polyethylene can basically meet the current requirements for polyethylene hardness by using high-density polyethylene, but the price of high-density polyethylene is relatively high, and then Increase the production cost of products made of high-density polyethylene, on the other hand, the insulation of high-density polyethylene is not high, and it does not have antibacterial properties
[0004] CN201410328788.9 discloses a resin composition that can be directly used for electroplating. The thermoplastic resin used in the composition is selected from ABS, PC, PP, PE, PA, PBT, PET, PMMA, ASA, AES or alloy resins thereof, But this composition only realizes being able to direct electroplating, and does not improve with improving insulation performance and antibacterial performance
CN200510043010.4 discloses a preparation method of a nano wave-absorbing plastic material and its products. The composition of the technical solution includes ABS, POM, PE, PA, PC, PMMA, PS, PVC and PTEE, etc. insulation and antibacterial properties

Abstract

The invention relates to an anti-mould PE (polyethylene) alloy with high hardness and friction resistance. The anti-mould PE alloy comprises raw materials in parts by weight as follows: 50-70 parts of PE, 10-30 parts of PMMA (polymethyl methacrylate), 0.2-0.6 parts of a compatilizer, 0.1-0.5 parts of an antioxidant, 4-10 parts of an anti-mould agent and 0.1-0.3 parts of a lubricant. With addition of PMMA with high surface hardness, the defect of low surface hardness of the PE material can be overcome, and the friction resistant effect is improved. The anti-mould performance of the material is improved through addition of CuBr or AgCl, Cu<+1> or Ag<+1> is dissolved out when CuBr or AgCl is added to the material, gets free gradually and binds with active proteins in mould when contacted with the mould, and the active proteins are inactivated, so that the mould is killed.
