Description
Technical field
The present invention relates to TPU Material Field, particularly to a kind of modified TPU material and preparation method thereof.
Background technology
TPU (Thermoplastic polyurethanes) entitled TPUE rubber.It is broadly divided into
Have polyester-type and polyether-type point, the features such as it has, and hardness range is wide, wear-resisting, oil resistant, transparent, good springiness, at commodity, body
Be used widely in the fields such as articles for use, toy, ornament materials of educating, and halogen-free flameproof TPU can also replace flexible PVC to meet
The environmental requirement in more and more fields.At present, the product that on market, TPU material is made gets more and more, but mostly simply has
The original feature of TPU, it is impossible to well meet the demand in market, it addition, also there is partial monopoly to disclose the making side of TPU material
Method, and the modification to TPU material, such as application publication number CN103665829A(2014-03-26) disclosed in environment protection high flame resistance heat
Plastic polyurethane method for producing elastomers, the elastomer of preparation maintains excellent lower temperature resistance, pliability and hydrolytic resistance,
And employing composite halogen-free fire retardant, ensure that the premium properties of elastomer itself greatly, not producing even if meeting fire burning
Raw environmentally harmful gas, can be widely used for the fields such as cable jacket, automobile component and oil hose, but this TPU material
Material can not well be applied to the fields such as household.
Summary of the invention
Present invention aim to address the problems referred to above, it is provided that a kind of modified TPU material and preparation method thereof, not only there is biography
The performance of system TPU, and also there is the effect of magnetic therapy, the method simple products of manufacture is easy to get, and is suitably applied household field, special
It is not suitably applied the mat fields such as mattress.
The above-mentioned technical purpose of the present invention has the technical scheme that
A kind of modified TPU material, it includes following components and weight portion:
PEPA: 30-130 weight portion
Diisocyanate: 30-110 weight portion
Dihydroxylic alcohols: 8-45 weight portion
Pore-creating agent: 3-11 weight portion
Polyurethane foams: 5-15 weight portion
Chain extender: 3-11 weight portion
Magnetic: 20-110 weight portion
The preparation method of described a kind of modified TPU material is as follows:
(1) diisocyanate of the PEPA of described 30-130 weight portion with described 30-110 weight portion is added to reaction
In still, it is heated to 80-110 DEG C, after melting, opens stirring；
(2) add the dihydroxylic alcohols of 8-45 weight portion after the mixing completely of the material in step (1), be then incubated 0.5-1h;
(3) carry out reactor lowering the temperature 60-80 DEG C, and add the pore-creating agent of 3-11 weight portion for the first time, gathering of 5-15 weight portion
Urethane foaming agent, and the chain extender of 3-11 weight portion, stir, and is then incubated 0.5-1.5h；
(4) reactor is vacuumized process, then carry out second time and lower the temperature, below temperature to 50 DEG C, then blowing；
(5) material released in step (4) is sent into mixer mixing, adds the magnetic of 20-110 weight portion, mix,
Obtain mixture；
(6) mixture described in step (5) is sent into plastics processing mill to heat plasticizing, by the raw material feeding filter after plasticizing, mistake
Filter impurity, prepares raw material；
(7) raw material described in step (6) is poured in the mould scribbling releasing agent in advance；
(8) mould in step (7) is put into drier together with described raw material, 60-150 DEG C of dry 0.5-2h is the coldest
But to room temperature, carry out modified TPU material with mould separating and take out modified TPU material.
Being mixed with magnetic by the TPU material made in this programme, the modified TPU material made not only has the performance of TPU, also increases
Add the effect of magnetic so that the modified TPU material hardness wide ranges made, wear-resisting, oil resistant, transparent, good springiness, and have
The effect of magnetic therapy, goes for the fields such as commodity, sports goods, toy, ornament materials.In industrial production preparation, if
Paying no heed to, uneven being easy to of temperature height occurs that local solidification causes whole material to become the phenomenon given up, the addition of metal material
More it is easily caused in TPU manufacturing process the probability that solidification occurs, and containing metallic element or metal oxide in magnetic, is producing
In, the probability that solidification occurs is the biggest, and this is also that other producers control bad technique, it is impossible to the reason of batch making, but
By the improvement to technique in this programme, well solve this problem so that modified TPU material and magnetic can well
Mixing, and do not interfere with the performance of TPU, not havinging the potential safety hazards such as solidification yet, the modified TPU material property made is excellent
More, can produce with bulk industrial, it addition, along with TPU quote extensive, traditional TPU performance is not well positioned to meet
Modernization, intensive requirement, be combined magnetic with tradition TPU and can make modified TPU material more use value, and magnetic
Treat and increasingly accepted by the mankind now, more convenient to use, more can provide curative effect for the healthy of the mankind.
The effect of magnetic therapy is as follows:
1. magnetic therapy can strengthen the vitality of white blood cell, and under the influence of a magnetic field, white blood cell phagocytosis function is more active, red blood cell and
The sedimentation of lymphocyte is slack-off, beneficially anti-inflammatory and reduction erythrocyte sedimentation rate.
2. magnetic therapy can improve blood circulation, strengthens oxygen and the absorption of irony, gets rid of the dirt in carbon dioxide and blood
Deng harmful toxins and fatigue substances.
3. magnetic therapy can produce electric current in vivo, and the elasticity increasing vascular wall distends the blood vessels, and reduces blood viscosity, accelerates blood
Stream, eliminates embolism.
4. magnetic therapy has reinforcement endocrine liquid osmosis, corrects endocrine imbalance and disorder.
5. magnetic therapy can stimulate the inductor of human body--excited nerve ending, regulate nervous function.
6. magnetic therapy can make algogenic substance such as bradykinin, 5-tryptamines, acidic metabolite etc. spread and disappear, and alleviates and eliminates
Pain.
And clinically it has proven convenient that the disease that can treat of every Traditional Chinese medicine blood circulation promoting silt therapy, magnetic therapy can be treated greatly,
And effect is fine, such as hemotoncus, hypertension, headstroke, coronary heart disease, diabetes, hydrothorax, ephritis, oedema, especially joint
Pain etc. all receive good effect, illustrate that the effect activated blood circulation and dispersed blood clots of magnetic therapy is the strongest.
