The performance of TPU film prepared by the TPU film preparing embodiment 1-5 and comparative example 1-12 is entered
Row measures, and method of testing is as follows:
(1) breathability test
Survey according to " water vapo(u)r transmission test method " regulation in appendix C in YY/T 0148-2006
Examination.
(2) water absorption test
Specify to test according to " the water absorption test method " in YY/T 0471.1-2004, obtain thin
The dressing that film is affixed on wound surface absorbed the average magnitude (g/100cm of liquid in 30 minutes2)。

(4) laminated film Mechanics Performance Testing
According to standard GB/T 13022-91, universal testing machine carries out Mechanics Performance Testing.
By table 1 data it can be seen that the TPU film breathability prepared of the present invention is high, bacteriostasis rate may be up to
More than 90%, and there is the most elastic and excellent mechanical property.
When being added without chitosan and silver nano-grain in TPU raw material, (comparative example 1) can make TPU film
Biocidal property be substantially reduced, when being added without chitosan, and when improving silver nano-grain consumption (comparative example 2),
Although its bacteriostasis rate can be improved to some extent, but compared with Example 1, still there is a big difference for tool,
Same when being added without silver nano-grain and improve chitosan dosage (comparative example 3), its bacteriostasis rate and enforcement
Example 1 is compared, and still there is a big difference for tool.Additionally, when the consumption of chitosan and silver nano-grain is beyond this
During bright described amount ranges (comparative example 4-5), its bacteriostasis rate is only capable of reaching 70%.
When being added without Polyethylene Glycol and polyvinylpyrrolidone in TPU raw material (comparative example 6), TPU is thin
The breathability of film, water absorption and elasticity all can be affected, additionally, its elongation at break and tension failure
Stress also can necessarily be damaged, when being only added thereto one (comparative example 7-8), although each performance has
Certain improve, but it is the most notable to improve effect, additionally, when Polyethylene Glycol and polyvinylpyrrolidone
Consumption too much or very few time, the performances such as the breathability of TPU film, water absorption and elasticity can be affected equally.
Therefore, in the present invention, the most described each raw material cooperates and could obtain bacteriostasis rate height, breathability
Good, water absorption rate is high, the TPU film of good springiness, it is adaptable to medical product application standard.
Applicant states, the present invention illustrates the medical product of can be used for of the present invention by above-described embodiment
