Embodiment

[0037] Hereinafter, examples of this invention will be described and described in more detail.

[0038] (Preparation of rubber composition)

[0039] The rubber compositions of Examples 1-3 and Comparative Examples 1-2 were compounded according to the compounding recipe in Table 1 with respect to 100 parts by weight of the rubber component, and kneaded with a normal Banbury mixer to adjust the rubber composition. Each compounding agent described in Table 1 is shown as follows.

Abstract

The invention provides a rubber composition with the fire-resisting property and the fatigue durability and a cushion by using the same. the rubber composition contains rubber component, amine age resister and wax, based on 100 weight parts of rubber component, the amine age resister is (A) and the wax is (B), wherein B is not less than 5.0 and not more than 10.0, the ratio of (A) to (B) is not less than 1.5 and not more than 3.0, preferably, the rubber composition contains 0.5 to 5 weight parts of sulfur and 0.5 to 5 weight parts of vulcanization accelerator based on 100 weight parts of rubber component.

Description

technical field [0001] The present invention relates to a rubber composition having both heat resistance and fatigue resistance, and an air cushion using vulcanized rubber obtained by vulcanizing and molding the rubber composition, such as an air cushion for automobiles or trains for cushioning . Background technique [0002] In recent years, many rubber products have been used for a long time under various severe conditions. In the market, rubber products are required to achieve high functionality and at the same time, rubber products are required to achieve long life. Therefore, it is strongly required to improve the fatigue resistance and heat resistance of the rubber material itself. For example, in vulcanized rubber materials constituting air-cushion products used in automobiles and railcars to play a cushioning role, and pneumatic tires, fatigue resistance, heat resistance, and weather resistance are particularly required to be improved. [0003] At present, in order...
