High-antibacterial and wear-resisting PVC (Polyvinyl Chloride) resin material and preparation method thereof

Abstract

The invention relates to the technical field of high molecular materials and relates to a high-antibacterial and wear-resisting PVC (Polyvinyl Chloride) resin material and a preparation method thereof. The high-antibacterial and wear-resisting PVC resin material is prepared from the following components in parts by weight: 100 parts of PVC resin, 10 to 40 parts of an antibacterial plasticizer, 8 to 12 parts of a stabilizer, 1 to 3 parts of a lubricant, 5 to 8 parts of an antioxidant, 3 to 5 parts of an anti-impact modifying agent, 5 to 20 parts of filler and 1 to 3 parts of an additive. According to the high-antibacterial and wear-resisting PVC resin material and the preparation method thereof, an antibacterial functional auxiliary agent and a plasticizing-promoting auxiliary agent are integrated, have a good plasticizing effect and a relatively strong antibacterial effect, and are matched with other components to have a mutual synergistic effect, so that the PVC material has a good antibacterial effect and good mechanical properties and weather-resisting performance; the application field and application field of PVC are greatly improved; furthermore, the preparation method provided by the invention is simple, preparation technological conditions are easy to control and the preparation efficiency is high; the raw material price and the production energy consumption are relatively low, so that the preparation method is suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high antibacterial and wear-resistant PVC resin material and a preparation method thereof. Background technique [0002] PVC (PVC) is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It is a homopolymer of vinyl chloride. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin. Because of its advantages of non-flammability, high chemical resistance, good electrical insulation performance, stable physical and chemical properties, and low price, it plays a very important role in industrial production and is widely used in industry, agriculture, transportation, construction, electronics, etc. Communications, household appliances, furniture, packaging and medical and health fields. It is also applied to infusion tubes, infusion bags, oxygen masks, toys, shoes, pipes, food packaging,...

Problems solved by technology

However, this type of plasticizer is toxic and has been banned by the US Consumer Product Safety Commission (CPSC) from being used in child care appliances and toy products. From the above-mentioned new environmental protection laws, it can be seen that for PVC plastics with a large amount and a wide range, its plasticizer It is imperative to make non-toxic and environmentally friendly modification of plasticizers, and phthalate plasticizers are bound to be eliminated, which makes the development of environmentally friendly and non-toxic new plastic plasticizers a hot spot in plasticizer research

At the same time, because PVC does not have antibacterial properties, the surface of its products will become dirty after a period of time, and various harmful microorganisms such as bacteria, molds, and fungi will breed.

Especially when the objective conditions such as temperature and humidity are suitable, it is easier to reproduce and spread harmful microorganisms. Contacting by different people will lead to cross-infection, become a source of bacterial pollution and disease transmission, and bring harm to human health. To a certain extent, PVC scope of application

In order to make PVC have an antibacterial effect, it is usually necessary to add some antibacterial agents, but commonly used antibacterial agents have poor compatibility with PVC resins. Like plasticizers, they are easy to precipitate in PVC resin systems, which makes the development of PVC industry Relying on new plasticizers and antibacterial agents, therefore, there is an urgent need for a PVC material with high stability, good compatibility, high mechanical strength, and excellent antibacterial properties to meet people's diverse needs for PVC material products
