The performance of TPU film prepared by the TPU film preparing embodiment 1-5 and comparative example 1-17 is entered
Row measures, and method of testing is as follows:
(1) antistatic property test: carry out test surfaces according to national standard standard GB/T/T1410-2006
Resistivity.
(2) coefficient of friction of TPU film is measured by pendulum method.
(3) laminated film Mechanics Performance Testing: according to standard GB/T 13022-91, at universal testing machine
On carry out Mechanics Performance Testing.
The result of above performance test is as shown in table 1:
Table 1
As can be seen from Table 1, the TPU film surface resistivity that prepared by the present invention is
5.2×105-7.5×105Ω, antistatic property is good, and anti-skidding coefficient of friction is 0.6-0.8, has good preventing
Slip energy.Additionally, the elastic modelling quantity of TPU film prepared by the present invention is 38-42MPa, elongation at break
For 550.52-628.25%, tensile break stress is 58.5-65.7MPa, good mechanical properties.
When TPU film prepare raw material is added without conductive carbon fibres peacekeeping glass fibre time (comparative example 1),
The surface resistivity of the TPU film prepared is higher, and coefficient of friction is relatively low, and the raising of mechanical performance is also
Inconspicuous；When be added without in conductive carbon fibres peacekeeping glass fibre any one, and improve the consumption of another one
Time (comparative example 2 and 3), although surface resistivity decreases, but and inconspicuous, and other aspects
The raising of performance the most notable, this explanation conductive carbon fibres peacekeeping glass fibre in this TPU film for
The raising of antistatic property has synergism.
When TPU film prepare raw material is added without nylon fiber and glass fibre time (comparative example 8), TPU
The coefficient of friction of thin film is 0.25, and its non-skid property is poor, and is added without when preparing in raw material of TPU film
Any one of nylon fiber and glass fibre, and when improving alternative consumption (comparative example 9 and 10),
The coefficient of friction of TPU film increases, but not notable, therefore, and Buddhist nun in the TPU film of the present invention
Dragon fiber and glass fibre have synergism in the skid resistance strengthening TPU film.
Just can obtain various aspects of performance additionally, cooperate between each component of the present invention and all compare excellent
TPU film, and when certain component therein too much or very few time (such as comparative example 4-7 and comparative example
11-17), each performance of TPU film can all be affected more or less.
Applicant states, the present invention illustrates the anti-skidding antistatic TPU film of the present invention by above-described embodiment
