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

Abstract

The invention relates to a high-rigidity PE (Polyethylene) alloy. The high-rigidity PE alloy is prepared from the following components in parts by weight: 50 to 70 parts of PE, 10 to 30 parts of PMMA(Polymethyl Methacrylate), 0.2 to 0.6 part of a compatilizer, 0.1 to 0.5 part of an antioxidant and 0.1 to 0.3 part of a lubricant. According to the high-rigidity PE alloy, the high-surface-rigidity material is added with the polymethyl methacrylate and the disadvantage that the surface rigidity of a polyethylene material is low can be improved, so that the effect of improving abrasion resistanceis realized.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a high-hardness PE alloy. Background technique [0002] Polyethylene (PE) is an important thermoplastic polymer with good dimensional stability, good insulation, water and oil resistance, and is widely used in household appliances, mechanical parts, office supplies and communication equipment and other fields. 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 The production cost of products made of high-density polyethylene is inc...
