Abstract

The invention discloses an environment-friendly high-transparency PVC composition for making medical infusion tubes, belonging to the technical field of medical PVC plastics. It is characterized in that the composition in parts by weight is: 100 parts of polyvinyl chloride resin, 1.0-3.0 parts of environmental heat stabilizer, 30-70 parts of citric acid ester plasticizer, 1-5 parts of epoxy soybean oil, ethylene glycol shrinkage 0.1-0.4 part of glycerol ether, 0.05-0.2 part of lubricant; the polyvinyl chloride resin is a PVC resin with an average degree of polymerization of 1000-2500. The composite plasticizing system composed of environmentally friendly citric acid ester as the main plasticizer, epoxidized soybean oil as the auxiliary plasticizer, and ethylene glycol glycidyl ether, which has an auxiliary stabilizing effect on chlorine-containing polymers, is used to plasticize PVC. Into high transparent PVC infusion tube. The raw material additives used are all non-toxic and environmentally friendly, and are environmentally friendly compositions.

Description

technical field [0001] The invention discloses an environment-friendly high-transparency PVC composition for making medical infusion tubes, belonging to the technical field of medical PVC plastics. Background technique [0002] In 1982, the National Cancer Institute of the United States proved that dioctyl phthalate (DOP) can cause cancer in the liver of rodents, and has a greater impact on the growth and development of the human body, especially infants and children. Citrate products can be used as plastic plasticizers, food additives, washing aids, cosmetic additives, etc., and are non-toxic, non-polluting, non-irritating, and biodegradable green chemical products. Citrate plasticizers have been approved by the US Food and Drug Administration (FDA) as non-toxic plasticizers, and can be used in food packaging, medical appliances, children's toys and personal hygiene products. Countries such as Europe, America, Japan and South Korea have used environmentally friendly plasti...
