Problems solved by technology

[0002] Polypropylene (PP) is one of the most widely used plastic products. It has the advantages of heat resistance, corrosion resistance, low density, and easy processing. It has been widely used in automobile industry, household appliances, food packaging, architectural decoration, etc. However, polypropylene is easy to age and has poor antibacterial properties. When the water meter made of polypropylene is used in southern my country, it is easy to breed bacteria and moss on its surface due to the influence of high temperature and moisture for a long time. The service life of the water meter

Abstract

An antibacterial anti-aging polypropylene composite material for a water meter casing is disclosed. Raw materials of the composite material include, by weight, 100 parts of polypropylene, 10-20 partsof POE, 2-4 parts of ultra high molecular weight polyethylene, 3-5 parts of polycarbonate, 1-5 parts of nanometer titanium dioxide, 3-8 parts of nanometer zinc oxide, 2-5 parts of glass fibers, 2-5 parts of quartz sand, 3-8.5 parts of ultrafine bamboo charcoal, 1-5 parts of talc powder, 2-7 parts of wollastonite, 0.05-0.15 part of an anti-ultraviolet agent, 0.1-0.2 part of an antioxidant, 0.5-1.2parts of itaconic acid, 0.1-0.38 part of dicumyl peroxide and 0.1-0.38 part of cinnamyl aldehyde. The composite material has high strength, good impact resistance, and excellent antibacterial performance and aging resistance.

Description

technical field [0001] The invention relates to the technical field of instruments, in particular to an antibacterial and aging-resistant polypropylene composite material for water meter shells. Background technique [0002] Polypropylene (PP) is one of the most widely used plastic products. It has the advantages of heat resistance, corrosion resistance, low density, and easy processing. It has been widely used in automobile industry, household appliances, food packaging, architectural decoration, etc. However, polypropylene is easy to age and has poor antibacterial properties. When the water meter made of polypropylene is used in southern my country, it is easy to breed bacteria and moss on its surface due to the influence of high temperature and moisture for a long time. the service life of the water meter. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes an antibacterial and aging-res...
