Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with examples. The modified chlorosulfonated polyethylene rubber of the present invention is chlorosulfonated polyethylene rubber modified by chlorinated polyether resin (CPS), and can also be the modified chlorosulfonated polyethylene rubber disclosed by China Chemical Industry Association on September 1, 2012. The modified chlorosulfonated polyethylene rubber mentioned in "Application of polyethylene rubber and air blocking agent NM360 in the inner layer adhesive of all-steel radial truck tire".

[0022] The natural rubber shock-absorbing support 52 (Shore A, degree) rubber material of automobile engine was selected as a representative, and the rubber properties before and after blending were studied. The rubber combination test formula is shown in Table 1:

Abstract

The invention discloses a high-aging-resistance rubber material and a preparation method thereof. The rubber material is characterized by mainly comprising natural rubber and modified chlorosulfonated polyethylene rubber, wherein the modified chlorosulfonated polyethylene rubber accounts for 0.1-5 wt% of the total amount of the natural rubber and modified chlorosulfonated polyethylene rubber. By fully utilizing the characteristic of heat oxidation aging resistance of the chlorosulfonated polyethylene rubber and the characteristic that sulfur can be adopted for vulcanization after modification, after the MCSM-120 is doped into the natural rubber, a vulcanization crosslinked network structure can be generated between the two rubber molecules, and the chlorosulfonated polyethylene rubber molecular chain is connected into the natural rubber molecular chain, thereby improving the stability of the natural rubber vulcanization crosslinked bond structure under high-temperature conditions, and enhancing the high temperature resistance, heat oxidation aging resistance, ozone resistance and weather resistance of the rubber shock absorber and nti-reversion property of the natural rubber.

Description

technical field [0001] The invention relates to the technical field of rubber materials, in particular to a rubber material with high aging resistance (compression set%, 100°C / 94h, 66.9%) and a preparation method thereof. The rubber formulation technology of modified chlorosulfonated polyethylene rubber (MCSM-120) can make full use of the thermal oxygen resistance, ozone resistance, weather resistance, oil resistance and chemical corrosion resistance of chlorosulfonated polyethylene rubber to improve and improve The natural rubber shock absorber's heat and oxygen aging resistance, ozone resistance and weather resistance can prolong the dynamic fatigue life of the shock absorber. Background technique [0002] The requirements of the automobile industry for natural rubber shock absorbers are constantly increasing, especially for products such as rubber shock absorbers for automobile engines and rubber shock absorbers for gearboxes. Under certain conditions, it has good heat a...
