Plant Polyether-type thermoplastic polyurethane elastomer.
Polyether-type thermoplastic polyurethane elastomer particle obtained by such scheme is molded into plastic-injection moulding machine
A diameter of 2cm, thickness are 3cm circular Polyether-type thermoplastic polyurethane elastomer test piece, then respectively gather the circle of gained
The test piece of ether type TPUE is by GB/T 2411-2008 (ISO 868-2003) in senior durometer rubber hardometer
On, determine its hardness under conditions of temperature (23 ± 2) DEG C；Meanwhile, by the polyether thermoplastic polyurethane bullet obtained by such scheme
Property body particle be molded in plastic-injection moulding machine growth 25mm, wide 6.1mm, the thick 2mm poly- ammonia of dumb-bell shape polyether thermoplastic
Ester elastomer, then presses GB/T 528-1998 (ISO by the dumb-bell shape Polyether-type thermoplastic polyurethane elastomer of gained respectively
37：2005) on electronic universal tensile testing machine, in temperature (23 ± 2) DEG C, humidity (50 ± 2%), draw speed is 200mm/
Its mechanics performance determining is determined under conditions of min；As a result show, the Polyether-type thermoplastic polyurethane elastomer obtained by the present invention is equal
It is 1783-1889% with flatness modulus and elongation at break is longer, and U.S.'s promise reputation polyether thermoplastic of same hardness gathers
Urethane elastomer ETHR-TYPE75AT3 products, its elongation at break is only 660%, and the polyether thermoplastic obtained by the present invention
The tensile strength of polyurethane elastomer in 3.997-8.24Mpa Mpa scopes, due to tensile strength and hard segment content and-OH with-
NCO mol ratio is relevant, therefore can be as needed, is adjusted by adjusting hard segment content and-OH with-NCO mol ratio
Its tensile strength.
Ultrasonic delivery device is set in the barrel of the injection machine, for stirring the slurry in barrel, makes various materials
Well mixed mixing, will not occur heavy poly- phenomenon.As shown in Fig. 2 the ultrasonic delivery device includes connecting high by wire
The ultrasonic transducer of the supersonic generator of frequency and the ultrasonic irradiation linked into an integrated entity with barrel fix block part, the ultrasound
Wave transducer is fixed block part by ultrasonic transformer and the ultrasonic irradiation and is connected.Ultrasonic irradiation fixes block part and is fixed on barrel
On.Ultrasonically treated processing frequency can be two frequency bands of 15-25KHz and 20-35KHz mixing, it is possible to reduce it is various not
Melting slurry production with density is heavy poly-, makes compound more uniform, steady quality.
Day leatherware produced by the present invention has good anti-wear performance, high resilience, strong corrosion resistant；Wherein, carbon fiber and ethene
Yl pyridines-vinyl imidazole block copolymer can produce synergy, enhance mechanical strength, while also improving day skin in tide
Service life in wet environment；There is low in interaction, increase footwear return between structure containing N heterocycles and the structure containing F
Elasticity, plays a part of buffering；Its skin bit has capillary hole characteristic, and when toe cap contacts ground, inside is in vacuum state, so that
Ground contact can form the effect of physics sucker, and greatly enhancing frictional force with ground friction coefficient plays anti-sprain effect；Material
It can play antifouling without footwear print by hydrophobic group raw material, play antifouling effect, have great application prospect.
The present invention is naughty, and outer bottom has improved skid resistance.Here skid resistance is by the dynamic of the static friction for determining footwear
The device measuring of state limiting angle -- the tester of static friction angle is measured to measure.In order to measure, outer bottom is bonded in model footwear
On face.In order to directly compare skid resistance, the size and curve of test specimen always must be identical.It is 3mm usually using thickness, it is long
Spend for 15cm, width is 10cm non-special-shaped right angle test film.For each circulation, the experiment footwear be placed on base material and and its
It is parallel, and it is loaded with adjustable weight of fixation.Before each circulation, increase the inclination angle of base material, until experiment footwear are slided
Off normal and put.For specific measurement, using steel plate as base material and 40kg load is selected.In order to measure in wet conditions, steel
Plate is consistently rinsed in process of the test with water.The measurement data of three samples randomly selected is as follows：
It can be seen that, the present invention has splendid skidproof effect.
After tested, composite of the present invention is taken out in full sample at random, each performance average out to：Tensile strength 72.60MPa,
Stretch modulus 992.34MPa, specific wear rate 38.47 (E-05mm3/Nm).More traditional TPU elastomer phases ratio, gained composite wood
The combination property of material, which has, to be greatly improved, and keeps TPU tensile properties, and intensity and rigidity are improved, abrasion effectively reduction.
Preferred embodiment of the invention described in detail above, be inventor take a large amount of manpower financial capacities and when
Between, test of many times come out it will be appreciated that, as a result, the ordinary skill of this area just can be according to this hair without creative work
Many modifications and variations are made in bright design.Therefore, all technical staff in the art according to present inventive concept in prior art
On the basis of by logic analysis, reasoning or according to the limited available technical scheme of experiment, should be by this right
Among protection domain determined by claim.
