Abstract

The invention relates to an environmental-protection type high transparency PVC composition for infusion tubes, wherein the components comprise, by weight, 100 parts of a polyvinyl chloride resin, 1.0-3.0 parts of an environmental-protection heat stabilizer, 30-70 parts of a citrate plasticizer, 1-5 parts of an epoxy soybean oil acrylate, 0.1-0.4 part of ethylene glycol glycidyl ether, and 0.05-0.2 part of a lubricant, wherein the polyvinyl chloride resin is a PVC resin having an average polymerization degree of 1000-2500. According to the present invention, PVC is plasticized by using the composite plasticizing system comprising ethylene glycol glycidyl ether providing the auxiliary stabilization effect for the chlorine-containing polymer, the environmental-protection type citrate is adopted as the main plasticizer, and the epoxy soybean oil acrylate is adopted as the auxiliary plasticizer to prepare the high transparency PVC infusion tube; and the used raw materials and the used auxiliary agent are non-toxic and environmentally friendly, such that the obtained the composition is the environmental protection composition.

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...
