Abstract
The invention discloses a TPE of environment protection and innocuity, which excludes PVC or other toxic substances. The TPE is polymerized mainly by ethylene, propylene, isoprene, styrene and ethylene branched isoprene based on certain proportion. The TPE is used for manufacturing infusion tubes, infusion bags and other medical supplies and is produced by mixing with polystyrene, polyethylene, polypropylene, ABS resin or filler materials, at the same time the transparency, shock absorption, tension and hardness of the products conform to the characteristics of the original PVC materials, which can not cause environment pollution.
Description
Technical field
The present invention relates to a kind of thermoplastic elastomer of environment-protecting asepsis, be used to make tubing, infusion bag and other medical treatment product.
Background technology
Existing tubing, infusion bag and the used macromolecular material of other medical treatment product all are to be main raw material with PVC so far.The PVC material contains the polyvinyl chloride monomer, is unfavorable for the health of human body, simultaneously PVC in process of production for a change its performance added softening agent (DEHP), in use have the DEHP stripping.DEHP is a kind of objectionable impurities, the serious harm HUMAN HEALTH.And the PVC quality is thicker, is unfavorable for processing, and the transmitance of oxygen, water vapour is higher, and thermal adaptability is poor, and high-temperature sterilization is yielding, and tensile strength is relatively poor, these drawbacks limit of PVC material its application aspect the transfusion medical treatment product.The a large amount of Biohazard Waste meetings that particularly contain the PVC material seriously cause environmental pollution, and softening agent in the PVC auxiliary agent and stablizer can produce pollution to underground water and soil when handling in the garbage loading embeading mode.And when handling, can produce a kind of carcinogens that is Dioxins with the burning mode.Therefore, the environmental administration of many countries and regions has issued that relevant laws and regulations forbid or limit a large amount of uses of PVC in the world.
Summary of the invention
The object of the present invention is to provide a kind of thermoplastic elastomer, be applied to tubing, infusion bag and other medical treatment product, can replace the PVC goods fully, simultaneously in the transparency of product, damping, anti-ly open, soft durometer all can meet original PVC properties of materials.
In order to achieve the above object, the present invention is realized by following technical scheme.
A kind of thermoplastic elastomer does not contain PVC or other toxic substance, it is characterized in that: this thermoplastic elastomer is mainly formed according to the certain proportion copolymerization by ethene, propylene, isoprene, vinylbenzene, ethene branching isoprene.
Described thermoplastic elastomer is used to make tubing, infusion bag and other medical treatment product, can with polystyrene, polyethylene, polypropylene, ABS resin or packing material blend after make.
Described thermoplastic elastomer can at room temperature cushion high vibration.
Thermoplastic elastomer provided by the invention can with polystyrene, polyethylene, polypropylene, ABS resin or packing material (as lime carbonate, talcum powder, mica, graphite or the like) blend after make medical treatment product, vibration damper floor, daily plastic cement articles for use, sports equipment, electronic accessory parts of various uses or the like.Be applied to tubing, infusion bag and other medical treatment product and can replace the PVC goods fully, simultaneously in the transparency of product, damping, anti-ly open, soft durometer all can meet original PVC properties of materials, can not cause environmental pollution.
Description of drawings
Below in conjunction with description of drawings the specific embodiment of the present invention is further elaborated.
Fig. 1 is a thermoplastic elastomer molecular structure of the present invention
Embodiment
Please refer to a kind of thermoplastic elastomer shown in the accompanying drawing 1, this thermoplastic elastomer does not contain PVC or other toxic substance, is applied to tubing, infusion bag and other medical treatment product.This thermoplastic elastomer is a kind of special thermoplastic elastomer that can at room temperature cushion high vibration (damping), has high transparent simultaneously.This thermoplastic elastomer has the triblock copolymer of styrene block and ethene branching isoprene block, the main various thermoplastic elastomers that form according to the different ratios copolymerization by monomers such as ethene, propylene, isoprene, vinylbenzene, ethene branching isoprene, have high transparent, molecular structure as shown in Figure 1.This thermoplastic elastomer can and polystyrene (PS), polyethylene (PE), polypropylene (PP), ABS resin or packing material (as lime carbonate, talcum powder, mica, graphite or the like) blend after make medical treatment product, vibration damper floor, daily plastic cement articles for use, sports equipment, electronic accessory parts of various uses or the like.In it and the molecular structure after PP and the PE copolymerization as follows:
This is that this thermoplastic elastomer is irregularly arranged polypropylene and ethene segmental co-polypropylene in main chain.Following table is the typical performance of this thermoplastic elastomer propylene-ethylene random copolymers:
| Performance | Index |
