Non-ortho-benzene medical soft polyvinyl chloride plastic and preparation method thereof

Abstract

The invention provides a non-o-benzene-type medical flexible polyvinyl chloride plastic and a process for preparation, and the components and the parts by weight are that polyvinyl chloride resin 100 parts, plasticizing agent 10-90 parts, stabilizing agent 1-10 parts, auxiliary stabilizing agent 1-10 parts, lubricating agent 0.2-5.0 parts and anti-oxidant 0-2 parts. The plasticizing agent is one and several of adipic acid propanediol ester, adipic acid diglycol ester, decanedioic acid butanediol ester, decanedioic acid propanediol ester, or adipic acid butanediol ester. The invention solves the bad effect which is caused by the dissolving out of phthalandione (2- ethylhexyl acrylate). The invention has the advantages that the invention not only keeps rich source of PVC material, but also the invention is easy to be processed and modified, and the products which are modified have excellent bioavailability, and the invention is applied in one time use, which can avoid cross-infection and the like. And the invention lowers the effects to environment, which belongs to environment-friendly-type products, and the performance of the products meets the existing standard requirements.

Description

technical field [0001] The invention relates to a medical soft polyvinyl chloride plastic which can be used for disposable medical products. Background technique [0002] As a material that is easy to process, has excellent mechanical properties and corrosion resistance, and has abundant raw material sources, polyvinyl chloride is widely used in various industries such as light industry, machinery, electronics, construction, and medical treatment. The currently commonly used dioctyl phthalate has always been used as a hygienic and The most cost-effective plasticizer is widely used in various PVC products. Since in 1980, the NCI (National Cancer Institute) of the United States believed that the incidence of liver tumors would increase based on the results of a two-year feeding study on rodents, and other research institutions had plasticized phthalates such as DOP. A comprehensive and in-depth study of the drug further showed that DOP has an impact on the development of the...

Problems solved by technology

Since in 1980, the NCI (National Cancer Institute) of the United States believed that the incidence of liver tumors would increase based on the results of a two-year feeding study on rodents, and other research institutions had plasticized phthalates such as DOP. A comprehensive and in-depth study of the drug further showed that DOP has an impact on the development of the male reproductive system in infants and young children, especially in male reproductive systems. It does not exist in the body, so the debate on DOP has not subsided so far, but the replacement of DOP has been carried out rapidly. The European Union decided to ban the use of phthalate plasticizers such as DINP in July 2005; Added a requirement to ban phthalic acid in toys made of soft polyvinyl chloride in the health amendment
