[0038] Next, the elastic composite materials of Comparative Example 1, Example 1, Example 2, Example 3, and Example 4 were manufactured according to the different formulations in Table 1 for subsequent physical tests. The test includes tensile stress, M300, and loss factor tanδ, and the results are shown in Table 2 below.

[0044] The vulcanization time (T 90@175°C) in Table 2 is based on ASTM D2084 and ISO3417 international standards, and the vulcanization degree and vulcanization time of a sulfur-containing rubber composite at high temperature (150°C-195°C) are analyzed by a rheometer. The relationship curve, the present invention is set to analyze at 175 ℃; M300 (kg / cm 2 ) represents the stress value at 300% stretching, the higher the value, the more rigid; the lower the value of tanδ, the smaller the rolling resistance. Can find through above table 2 result: when adding this bi...
