Abstract

The invention discloses phthalate-free medical polrvinyl chloride (PVC) plastic. The plastic is prepared by blending the following components in part by weight: 100 parts of PVC resin, 25 to 95 parts of eco-friendly plasticizer, 0.1-8 parts of polyolefin and chloroethylene function modifier, 4.5-9 parts of high-efficiency heat stabilizer and 0.3-1.5 parts of lubricant, wherein the eco-friendly plasticizer is cyclohexane1,2-diisononyl phthalate, SOFT-N-SAFE, EPN or acetyl tributyl citrate; the polyolefin and chloroethylene function modifier is more than two of styrene, maleic anhydride, diethyl maleate and chloroethylene; the chloroethylene is more than one of powdery, pasty and liquid calcium and zinc heat stabilizer; and the lubricant is butyl stearate or oxidized polyethlene wax. The phthalate-free medical PVC plastic is used for producing disposable medical supplies and is safe because the plastic is phthalate-free.

Description

technical field [0001] The invention relates to the field of medical polyvinyl chloride plastics for producing disposable medical supplies, in particular to a medical polyvinyl chloride plastic without phthalates. Background technique [0002] Products such as medical transfusion blood vessel, transfusion tube, transfusion bag, catheter, intubate and oxygen mask of prior art mainly all are made of medical polyvinyl chloride plastics. Medical polyvinyl chloride plastic is widely used in medical equipment, mainly because medical polyvinyl chloride plastic itself has good physical properties. These physical properties include: the convenience of making medical polyvinyl chloride plastics, and the good compatibility between such materials and intravenous (intravenous, IV) injection fluids and blood. Therefore, in terms of medical treatment, this plastic product has excellent performance and is used Convenient and very popular with users. However, the hardness and flexibility o...
