Abstract

The invention relates to the field of plastic products, and in particular relates to a production process of a plastic film with an antibacterial function. The production process is characterized by comprising the following steps: (1) uniformly mixing an antibacterial agent, polyvinyl chloride particles and an auxiliary agent in a mass ratio of 1:3:1; (2) heating the mixture obtained in the step (1), and keeping the temperature at 100-110 DEG C for 30-45 minutes to obtain a molten-state mixture; (3) cooling the molten-state mixture to ensure that the temperature thereof is kept between 60 and 70 DEG C; and (4) performing secondary mixing on the mixture and plastic resin, and then performing injection molding or extrusion molding to obtain the plastic film with the antibacterial function. The production process provided by the invention is simple and low in cost, and the produced plastic film with the antibacterial function is good in antibacterial effect and long in duration and has relatively strong market competitiveness.

Description

technical field [0001] The invention relates to the field of plastic products, in particular to a plastic film production process with antibacterial function. Background technique [0002] Plastic is a synthetic polymer compound {polymer}, also known as macromolecules or macromolecules, and is also commonly known as plastics or resins, which can change shape freely. It is a material made of monomer raw materials by synthesis or condensation reaction polymerization, and is composed of synthetic resins and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. [0003] The main component of plastic is synthetic resin. The term resin was originally named after the lipids secreted by animals and plants, such as rosin, shellac, etc. Resin refers to a high polymer that has not been mixed with various additives. Resin accounts for about 40% to 100% of the total weight of the plastic. The basic properties of plastics are mainly determined by the nature of ...
