Resistance to low temperature is tested
The brittleness temperature of embodiment 7-12 is measured according to the single specimen method that measures of GB/T 1682-2014 vulcanite black brittleness.
Table 1 resistance to low temperature testing record sheet
Note: rubber can become fragile under cryogenic, the brittleness temperature of rubber is the lowest, shows that the resistance to low temperature of rubber is the best.
As known from Table 1, embodiment 7-12 is respectively provided with good resistance to low temperature.But the resistance to low temperature of embodiment 12 is wanted
Significantly lower than embodiment 7-11, it is seen that the addition of N-(1,3-dimethyl) butyl-N '-diphenyl-para-phenylene diamine and activator makes this
Bright resistance to low temperature gets a promotion.In embodiment 7-11, the resistance to low temperature of embodiment 9 is slightly better than other embodiments.
Hardness test
Embodiment 7-12 is gone out with reference to GB/T 531.1-2008 vulcanite or thermoplastic elastomer penetration hardness determination of test method
Hardness.
Table 2 hardness test log
As known from Table 2, the hardness of embodiment 7-12 is higher.But hardness embodiment 7-11 to be significantly lower than of embodiment 12, can
See that the addition of N-(1,3-dimethyl) butyl-N '-diphenyl-para-phenylene diamine and activator makes the hardness of the present invention get a promotion.In reality
Executing in example 7-11, the hardness of embodiment 9 is slightly better than other embodiments.
Comparative example 1
Select the embodiment 1 as a comparison case 1 of the Chinese patent of Publication No. CN102850600A.
Comparative example 2
As different from Example 9 diisooctyl phthalate is replaced with dimethyl phthalate, other all with implement
Example 3 is identical.
Comparative example 3
As different from Example 9 adipic acid dibutyl ester being replaced with triphenyl phosphate, other are the most the same as in Example 9.
Comparative example 4
Remove N-(1,3-dimethyl) butyl-N '-diphenyl-para-phenylene diamine as different from Example 9, other all with embodiment 9 phase
With.
Comparative example 5
Removing activator as different from Example 9, other are the most the same as in Example 9.
