Abstract

The invention relates to a thermoplastic elastomer (TPE) composite material, which consists of a polyolefin thermoplastic elastomer (TPO), a styrene thermoplastic elastomer (SBC) and a polyurethane thermoplastic elastomer (TPU), wherein each 100 weight portions of the thermoplastic elastomer (TPE) comprise 30 to 70 portions of the polyolefin thermoplastic elastomer (TPO), 1 to 50 portions of the styrene thermoplastic elastomer (SBC) and 1 to 50 portions of the polyurethane thermoplastic elastomer (TPU). The material has stable chemical properties, is difficult to decompose after being processed, has no smog, and does not pollute the environment due to production of carbon dioxide after burning treatment; and a transfusion system manufactured does not need to be added with low molecular compounds such as a stabilizer, a lubricant and pigment. The thermoplastic elastomer (TPE) composite material has a reasonable formula, stable performance and good flexibility, elasticity and toughness, does not pollute the environment when being destroyed, and is a special material which can be used for mass production of portable thermoplastic elastomer transfusion systems in a cleaning shop.

Description

technical field [0001] The invention relates to a polymer material, in particular to an improved thermoplastic elastomer (TPE) composite material. It is specially used for making disposable thermoplastic elastomer (TPE) infusion set. Background technique [0002] We know that the infusion set is a kind of disposable medical device with a large amount and a wide range, and the annual consumption in the whole country reaches more than 5 billion. The quality of the infusion set and the safety of use are directly related to everyone's health. At present, disposable medical devices at home and abroad generally use PVC as raw material. PVC material has the advantages of excellent comprehensive physical properties, low price, and simple production process. However, due to the addition of a large number of chemical additives to the PVC material during processing and the carcinogens remaining in the material itself, the PVC infusion set contains a small amount of vinyl chloride co...
