Antibiosis aging-resistant polyvinyl chloride material and preparation method thereof

Abstract

The invention provides an antibiosis aging-resistant polyvinyl chloride material, of which a formula comprises raw materials in percentage by weight: 70-90 percent of polyvinyl chloride, 3-6 percent of plant source extract, 6-20 percent of nano loess, 0.7-2.5 percent of epoxy pomegranate seed oil, and 0.3-1.5 percent of octadecyl 2-hydroxyethyl amine oxide. The above raw materials are reasonably compounded through multiple machining means, synergistic interaction is realized, and the polyvinyl chloride material is endowed with multiple effects of natural antibiosis, mildew proofing, antioxidation, UV resistance, far infrared health care and the like, and a product prepared from the polyvinyl chloride material is wide in antibiotic spectrum, strong in bacteriostatic ability and durable in antibiosis effect. The aging resistance and mechanical properties are more excellent, and the material has no color change, deformation and cracking after being exposed for a long term in the sun, and is long in service life. Meanwhile, due to an infrared effect, actions of self cleaning, environment air purifying and peculiar smell eliminating are realized, the material is favorable for human health and environment-friendly and the application range of the polyvinyl chloride is greatly expanded.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antibacterial and aging-resistant polyvinyl chloride material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (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, p...

AI Technical Summary

Problems solved by technology

However, natural antibacterial agents are usually extracted from a plant, animal or organism, with a single antibacterial component and a narrow antibacterial spectrum. They have poor compatibility with polyvinyl chloride, and are prone to problems such as agglomeration and uneven dispersion. Antibacterial ingredients are easy to precipitate during use, and the antibacterial effect cannot last

In addition, the existing antibacterial agents cannot have both antibacterial and aging resistance and health care functions at the same time. In order to achieve the anti-aging indicators required for PVC products, antioxidants are usually added to polyethylene by blending modification to improve its resistance. Aging performance

However, most of the known antioxidants are small molecular compounds with certain toxicity, which tend to gradually precipitate on the surface of PVC products under the action of sunlight, oxygen and heat, which are prone to failure and hidden health and safety hazards.
