(2) laminated film Mechanics Performance Testing：According to standard GB/T 13022-91, power is carried out on universal testing machine
Learn performance test.
The result of above performance test is as shown in table 1：
Table 1
As can be seen from Table 1, the TPU film anti-flammability that prepared by the present invention reaches V-0 grades, and heat resistance is good, modulus of elasticity
For 37-45Mpa, with good elasticity, elongation at break is 575-625%, and tensile break stress is 62.4-68.8MPa, power
Learn functional.
When being added without organosilicon and tributyl phosphate in the preparing raw material of TPU film (comparative example 1), prepare
TPU film anti-flammability is only capable of reaching V-2 grades, when addition any one of organosilicon and tributyl phosphate, and is added without another
When, and improve alternative consumption and make it equal to (comparative example during the consumption sum of organosilicon and tributyl phosphate in embodiment 1
2 and 3), although fire resistance can be improved to a certain extent, but be also only capable of reaching V-1 grades, hence it is demonstrated that organosilicon and phosphorus
Sour tributyl has synergy on fire resistance is improved.
(comparative example 6), the heat resistance of TPU film, bullet when nylon fiber in the preparing raw material of TPU film and glass fibre
Property and mechanical property be substantially less than TPU film obtained by embodiment, when adding one in nylon fiber and glass fibre, and carry
The consumption of high another one, when making its consumption equal to nylon fiber in embodiment 1 and glass fibre consumption sum (comparative example 7 and 8),
Although heat resistance, elasticity and mechanical property increase, not significantly, therefore, in the present invention nylon fiber and
Glass fibre has synergy in terms of elasticity, heat resistance and the mechanical property of TPU film is improved.
Compare excellent TPU film in addition, being cooperated between each component of the present invention and can just obtain various aspects of performance,
