Abstract
The invention provides a thermoplastic elastomer granule for a medical infusion apparatus. The thermoplastic elastomer granule comprises, by mass, 50-70 parts of a polyolefin thermoplastic elastomer, 40-60 parts of a styrene thermoplastic elastomer, 20-50 parts of a polyurethane thermoplastic elastomer, 10-30 parts of a softener, 5-10 parts of a hardener and 1-5 parts of an anti-oxidant. The thermoplastic elastomer granule can be used as a material of a medical infusion apparatus conduit and a drip chamber. The thermoplastic elastomer granule has good extensibility and flexing resistance, high strength, wear resistance, good biocompatibility, no teratogenesis, no anaphylactic reaction, good blood compatibility, good antithrombotic performance, no damage to blood components, and excellent physical and mechanical properties and processing properties.
Description
Technical field
The invention belongs to field of medical materials, specifically, the present invention relates to a kind of thermoplastic elastomer pellet for medical Transfusion device.
Background technology
Thermoplastic elastomer (Thermoplasticelastomer, TPE) is that a class shows caoutchouc elasticity at normal temperature, and the macromolecular material of high temperature energy plasticizing forming, has the characteristic of rubber and thermoplastics concurrently.Its polymer segment is made up of plastics section (hard section) and rubber segments (soft section of elasticity).TPE normal temperature has the characteristic of vulcanized rubber, and high temperature presents the processing characteristics of thermoplastics, is called as " third generation rubber " after natural rubber, synthetic rubber.Thermoplastic elastomer can be divided into reaction copoly type and rubber plastic blend type two types.
The Application Areas of TPE is a lot of, and wherein medical article is one of its main application fields, is widely used in medical packaging, liquid and blood storage infusion and all kinds of conduit, medical facilities accessory etc.This is because with rubber phase ratio, TPE does not need sulfuration, can adopt the injection-molded of thermoplastics or extrusion moulding complete processing, even can carry out secondary injection molding on some base materials, simplify production process, reduce costs; Compared with thermoplastics, TPE can recycle, economic environmental protection.Except possessing the advantage of this processing characteristics, TPE has also possessed superior chemistry, physics and biological property, as antioxidant property is good, durometer level is wide, nontoxic etc., it is the shortcoming that compensate for plastics and rubber,, these special performances make it to become the manufacturing first-selection of medicine equipment for union plastics and rubber advantage.
Summary of the invention
For a thermoplastic elastomer pellet for medical Transfusion device, composed of the following components according to mass fraction meter:
Wherein, described tenderizer is white oil; Described stiffening agent is stearic acid; Described antioxidant is Ronotec17;
Its preparation method is: after polyolefins thermoplastic elastomer, styrene analog thermoplastic elastomer, polyurethane-type thermoplastic's elastomerics, tenderizer, stiffening agent, antioxidant being mixed in mixer, through twin screw extruder extruding pelletization.
The thermoplastic elastomer pellet adopting technical scheme provided by the invention to obtain can as the conduit of medical Transfusion device, dropping funnel materials'use.Beneficial effect of the present invention is: this pellet has good extensibility and resistance to flexing, intensity is high, wear-resistant, good biocompatibility, without aberration inducing effect, without anaphylaxis, blood compatibility, antithrombotic property are good, and not blood injury composition, there is excellent physical and mechanical properties and processing characteristics simultaneously.
