Abstract

The invention discloses a polyvinyl chloride material with good antibiosis and anti-ultraviolet properties. The polyvinyl chloride material comprises, by mass, 55-75% of polyvinyl chloride, 5-10% of di(2-ethylhexyl)phthalate, 6-12% of nanometer attapulgite, 5-8% of ethylene-octylene copolymer, 3-7% of methacrylate-acrylate copolymer, 1-3% of polyethylene glycol alkyl ether, 1-2% of an ultraviolet ray absorber, 0.5-1.5% of a calcium and zinc composite stabilizer, 0.5-1% of calcium stearate, 0.1-0.5% of nanometer silver and 0.1-0.5% of an antioxidant 1010. The polyvinyl chloride material has excellent antibiosis and anti-ultraviolet effects, has an antibiosis rate reaching above 98%, and also has the advantages of good heat stability, high impact strength, wide adaptation range, low cost, and easy popularization and application.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polyvinyl chloride material with good antibacterial and ultraviolet resistance. Background technique [0002] Polyvinyl chloride (PVC) is one of the five general-purpose resins, and its output is second only to polyethylene (PE). Because PVC has the advantages of high chemical resistance, good electrical insulation performance, stable physical and chemical properties, and low price, At present, it has been widely used in various fields such as industry, agriculture, transportation, construction, communication and medical care. However, pure polyvinyl chloride has problems such as poor thermal stability, poor weather resistance, and low impact toughness, which will greatly limit its application range. Therefore, polyvinyl chloride usually needs to add a second component to improve its performance, so as to better improve its performance. Contents of the invention ...
