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

Abstract

The invention relates to high-hardness friction-resistant antibacterial PE alloy. The high-hardness friction-resistant antibacterial PE alloy is prepared from, by weight, 50-70 parts of PE, 10-30 parts of ABS, 0.2-0.6 part of a compatilizer, 0.1-0.5 part of an antioxidant, 4-10 parts of an antibacterial agent and0.1-0.3 part of lubricant. By adding the high-surface-hardness material ABS, the shortcoming of low surface hardness of polyethylene material can be overcome, and the effect of improving friction resistance is achieved. By adding cuprous bromide or silver chloride, the antibacterial performance of the material is improved, Cu<+1> and Ag<+1> of the cuprous bromide or silver chloride are dissolved in the material and gradually dissociate to bind with active proteins in mould bodies to deactivate the proteins when being in contact with mould, and accordingly a mould killing effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a high-hardness, friction-resistant and antibacterial 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 It increases the production cost o...
