Choose the general-utility car inner tube of a tyre, the air tube that the imported auto inner tube of a tyre is prepared with the embodiment of the present invention 1 is compared.It is anti- Ageing time is detected by ageing oven, and it is 120 DEG C to adjust test temperature, relative humidity 85%, and air pressure is 106kPa, ozone concentration 45%, ultraviolet irradiation intensity 25mW/cm2;Compression strength is carried out using intensity test machine Test.Test result is as shown in table 2 below:
Table 2
Project Ageing time Compression strength/MPa
The general-utility car inner tube of a tyre 20~28 days 80
The imported auto inner tube of a tyre 35~40 days 83
1 inner tube of a tyre of the embodiment of the present invention 3~4 months 100
As seen from the above table, as compare different air tube tested under the same conditions obtained by data can Know, air tube prepared by the embodiment of the present invention 1 extends 350% than the ageing time of the general-utility car inner tube of a tyre, and compression strength improves 25%;Air tube prepared by the embodiment of the present invention 1 extends 157% than the ageing time of the imported auto inner tube of a tyre, and compression strength carries It is high by 20.5%.Show that the ageing time of air tube prepared by the present invention is longer, compression strength higher.
Several embodiments of the invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the guarantor of the present invention Protect range.
