Problems solved by technology

[0003] The existing modified polypropylene PP plastics have low antibacterial properties. After long-term use, bacteria are easy to breed on the surface of the plastics, which in turn causes virus infection, and some polypropylene PP plastics are added with antibacterial agents to increase antibacterial properties. The antibacterial agent has a single antibacterial effect, which makes the antibacterial effect poor and easy to precipitate, which makes the antibacterial durability of polypropylene PP plastics low

Abstract

The modified polypropylene PP plastic is prepared from the following raw materials in parts by weight: 80-100 parts of polypropylene, 8-10 parts of an antibacterial filler, 2-5 parts of a flame retardant, 3-5 parts of a dispersing agent, 3-5 parts of a plasticizer and 2-3 parts of glass fibers. The antibacterial filler can act on lipid or peptidoglycan in bacterial cell walls to destroy the structure of the lipid or peptidoglycan and cause damage to the bacterial cell walls, and after the antibacterial filler is mixed with a polymer, antibacterial substances in the antibacterial filler cannotmigrate and separate out in the long-term use process of the polymer, so that the antibacterial property of the polymer is more durable, and the service life of the polymer is prolonged. When the polymer is illuminated, the antibacterial filler can form positive holes and release free electrons at the same time, the free electrons can be absorbed by oxygen molecules and become negative oxygen ionswith extremely high chemical activity, and the negative oxygen ions can oxidize organic matters in bacteria so as to kill the bacteria.

Description

technical field [0001] The invention belongs to the technical field of plastic preparation, and in particular relates to a modified polypropylene PP plastic. Background technique [0002] Polypropylene is a colorless, odorless, non-toxic, translucent solid substance. Polypropylene is a thermoplastic synthetic resin with excellent performance. It is a colorless and translucent thermoplastic lightweight general-purpose plastic with chemical resistance and heat resistance. properties, electrical insulation, high-strength mechanical properties and good high wear-resistant processing properties, etc., which makes polypropylene rapidly used in machinery, automobiles, electronic appliances, construction, textiles, packaging, agriculture, forestry, fishery and food industries, etc. Many fields have been widely developed and applied. In recent years, with the rapid development of packaging, electronics, automobiles and other industries, polypropylene materials are gradually replacing...
