TPU material is obtained, respectively according to the requirement of " GB18173.1-2012 high polymer waterproof material first part: sheet material " JS2, to institute
It obtains TPU material sample and carries out performance detection, acquired results are as shown in table 1-8:
TPU material property prepared by 1 embodiment of the present invention of table, 1 composition
TPU material property prepared by 2 embodiment of the present invention of table, 2 composition
TPU material property prepared by 3 embodiment of the present invention of table, 3 composition
TPU material property prepared by 4 embodiment of the present invention of table, 4 composition
TPU material property prepared by 5 embodiment of the present invention of table, 5 composition
TPU material property prepared by 6 embodiment of the present invention of table, 6 composition
TPU material property prepared by 7 embodiment of the present invention of table, 7 composition
TPU material property prepared by 8 each comparative example composition of the present invention of table
It can be seen that after the present invention is added to filler by table 1-4, the mechanical property and ageing-resistant performance of products obtained therefrom are equal
There is the decline of fine degree.Under normal conditions, the usage ratio of thermoplastic polyurethane is higher, the mechanical property of products obtained therefrom
It is better, but since the cost of material of thermoplastic polyurethane is excessively high, high cost product produced is difficult to base oneself upon on the market.It uses
Filler can significantly reduce cost, and the use of filler can often significantly reduce the mechanical property of products obtained therefrom, and the present invention adopts
With the filler of special component and dosage, influence of the use of filler to products obtained therefrom performance is significantly reduced.And it is anti ultraviolet agent, anti-
The use of oxidant and stabilizer is the ageing-resistant performance to improve products obtained therefrom, but when being added to filler, is equivalent to institute
The content ratio for obtaining the anti ultraviolet agent in product, antioxidant and stabilizer decreases, and leads to the resistance to ag(e)ing of products obtained therefrom
Can also there be the decline of fine degree.
It can be seen from Table 8 that the shadow only with the product that thermoplastic polyurethane and filler are prepared, by filler
It rings, being remarkably decreased occur in the mechanical property and ageing-resistant performance of products obtained therefrom.Anti ultraviolet agent, anti-oxidant is not used respectively
Agent, the mechanical property of fire retardant and stabilizer products obtained therefrom and ageing-resistant performance also occur respectively under in various degree significant
The performance of drop or even mechanical property is more worse than the product being prepared only with thermoplastic polyurethane and filler.And it uses simultaneously
Anti ultraviolet agent, antioxidant, fire retardant and stabilizer products obtained therefrom, compared to not using anti ultraviolet agent, antioxidant, fire-retardant respectively
Agent and stabilizer products obtained therefrom, resistance to ag(e)ing can further increase on the original basis, while can significantly improve gained
The mechanical property of product, substantially overcome using filler bring mechanical property significantly reduce the problem of, embody anti ultraviolet agent,
Antioxidant, fire retardant and the significant synergistic function of stabilizer have unexpected technical effect.
It can be seen that the TPU material being prepared using the present composition by table 1-7, there is prior art material
Incomparable intensity it is high, good toughness is wear-resisting, resists cold, and ageing-resistant, the characteristics such as weatherability are both also to have high Waterproof Breathable
Property, radix saposhnikoviae, cold-proof, antibacterial, mould proof, warming, uvioresistant and energy release etc. many excellent functions.In artificial climate purple
After outside line accelerated aging test, the TPU changes in material properties that is prepared using the present composition better than the prior art its
His material and non yellowing.And equally after thermal aging test, using the performance for the TPU material that the present composition is prepared
Conservation rate is also quite stable.It can be seen that being had using the TPU material that the present composition is prepared ageing-resistant resistance to well
Imparted energy.The TPU material weather resistance being prepared using the present composition is superior, UV resistant with super strength,
Resistance to natural aging ability.The TPU material being prepared using the present composition not plasticizer-containing, without prior art material because
Quick aging phenomenon caused by plasticizer exudation, delay, greatly prolongs the service life of coiled material.Using present composition system
Standby obtained TPU material has excellent low temperature flexibility performance (- 35 DEG C), it is ensured that product is normal under the conditions of puna
It uses.There is excellent chemical resistance using the TPU material that the present composition is prepared, resistance to various acid, alkali, grease are rotten
Erosion, and have good resistance to degradation caused by bacterium, fungi and algae.It is prepared using the present composition
TPU material has high-tear strength, high extension, has good non-deformability.It is prepared using the present composition
Obtained TPU material be it is a kind of there is very strong high-tension, high-tensile strength, the environment-friendly materials of obdurability and the characteristics such as ageing-resistant.
