Description

Antibacterial do not separate out Polyurethane Thermoplastic Elastomer and preparation method thereof
Technical field
The present invention relates to a kind of antibacterial not separate out Polyurethane Thermoplastic Elastomer and preparation method thereof, belong to polyurethanes technology Field.
Background technology
Polyurethane Thermoplastic Elastomer (TPU) is by polyisocyanates with the polyethers of hydroxyl or polyester diol or low The linear polymer that molecule glycol chain extender reacts to each other and synthesizes.TPU has the thing of plastic processing performance and rubber concurrently Reason mechanical property and strength character, it is wear-resisting, oil resistant, low temperature resistant, radiation resistance is the most excellent, can be made into various industry system Product, its application almost penetrates into each industrial circle, but, common Polyurethane Thermoplastic Elastomer does not has antibacterial merit Can, there is also the problem that additive easily separates out, it is impossible to enough meet the requirement of medical industry.
Summary of the invention
It is an object of the invention to provide and a kind of antibacterial not separate out Polyurethane Thermoplastic Elastomer, have additive do not separate out, The feature that anti-microbial property is superior, present invention simultaneously provides its preparation method.
Of the present invention antibacterial do not separate out Polyurethane Thermoplastic Elastomer, be made up of the raw material of following mass fraction:
Wherein:
The model of described PEPA is PBA-2000；
Described antibacterial is with glass as carrier, and appendix has the inorganic antiseptic of silver ion, preferred manufacturer For Shi Xiaozi Co., Ltd. of Japan；
Described antioxidant is 1010；
Described lubricant is Tissuemat E.
Described elastomer is oval granule, and density is 1.15-1.25g/cm3, antibacterial, antioxidant and lubricant exist There is inside and outside elastomer particles identical concentration.
The hardness of described elastomer is Shao Shao A65-D72.
Of the present invention antibacterial do not separate out method for preparing thermoplastic polyurethane elastomer, comprise the following steps:
(1) PEPA of proportional quantity, BDO, MDI being added separately in three mixing kettles, temperature is respectively It is maintained at 80-120 DEG C, 40-80 DEG C, 50-80 DEG C, in PEPA, then adds antibacterial, antioxidant and lubricant；
(2) component in three mixing kettles is poured into the sprue gate of double screw extruder, by double spiral shells by casting machine Bar extruder carries out the polymerization of material, mixes, plastifies and pelletize, obtains after drying antibacterial not separating out thermoplastic polyurethane elastic Body.
Wherein, preferred technical scheme is as follows:
In step (2), extrusion temperature is 150-220 DEG C.
Antibacterial in the present invention can the most slowly discharge a small amount of silver ion, due to bacterium surface with Negative charge, is attracted to bacterium surface thus with the silver ion of positive charge, and then destroys the balance of its electrolyte, thus promotes Antibacterial is impaired and dead due to cell wall.
Beneficial effects of the present invention is as follows:
The antibacterial Polyurethane Thermoplastic Elastomer that do not separates out of the present invention has stable chemical nature, is prone to cleaning, mechanicalness The feature that energy is good, ageing-resistant performance is splendid, grease resistance, acid and alkali-resistance, excellent spring, additive do not separate out, anti-microbial property is superior is right The antibiotic rate of staphylococcus aureus, escherichia coli etc. is more than 99%, is particularly well suited as preparing medical tube for transfusion, mother and baby The raw material of articles for use, is the most potential Novel environment-friendlymaterial material, and its preparation method is simply, easily operate.
