Embodiment 1～3 and comparative example 1～12

[0020] The composition (rubber) formulations of Examples 1 to 3 and Comparative Examples 1 to 12 are all listed in Table 1, and the amount of each compounding component is in parts by weight, wherein, PNR is polynorbornene rubber, and QM is silicone rubber (In this example, methyl vinyl silicone rubber is used); the compatibilizer is a 1:1 (by weight) blend of EPDM rubber and ethylene-methyl acrylate copolymer; the coupling agent is vinyl triacetyl Oxysilane (A-151); peroxide is 2,5-dimethyl-2,5-(tert-butylperoxy)hexane [bis-2,5], DCP in Comparative Example 11 is peroxide Dicumyl oxide; dispersant is AF-52 produced by German Rheinland Chemical Company. All rubber materials except Comparative Example 12 were mixed with a 130°C internal mixer, and then added a vulcanizing agent (peroxide) with an open mixer at room temperature. Comparative example 12 adopts internal mixer normal temperature mixing process. Comparative Examples 1 and 2 are that the blending ratio of two kinds o...

Abstract

The invention relates to a high-temperature resistant and high-damping rubber composition using polynorbornene rubber as a main body, which is characterized in that the composition bases on blending of the polynorbornene rubber and silicon rubber, uses blend of ethylene propylene diene rubber and ethylene-methyl acrylate copolymer as a compatibilizer for blending the polynorbornene rubber and the silicon rubber, simultaneously uses 2, 5-dimethyl-2, 5 (tertbutylperoxy) hexane as a vulcanizing agent and a vinyl triethoxy silicane as coupling agents. The rubber materials are mixed in an internal mixer at a temperature of 130 DEG C.

Description

technical field [0001] The invention relates to the rubber product industry in the field of chemical industry, in particular to a rubber composition for manufacturing high-temperature-resistant rubber products with functions of vibration and noise reduction. Background technique [0002] In contemporary society, people generally pursue a comfortable and quiet life, so there is a special demand for materials and products with vibration and noise reduction functions. Especially when automobiles become one of the indispensable means of transportation for people, higher and higher requirements are put forward for the ride comfort, driving safety, high-speed performance and luxury ride of automobiles. In order to solve the pollution problems, safety problems and noise problems caused by the extensive use of automobiles, relevant scientific and technical engineers and technicians have done a lot of work. One of the important issues is to take vibration and noise reduction measures...
