Problems solved by technology

Ethylene-propylene rubber has very good electrical insulation properties and certain heat resistance, and can be used for a long time at an ambient temperature of 120 ° C. It begins to decompose slowly, and after a long time of aging, the rubber becomes hard and loses its use value
[0005] In recent years, the automobile industry has continued to develop, and its focus has always been on small and medium-sized vehicles, especially cars, which have higher requirements for vehicle safety and comfort. Therefore, the operating temperature and service life of auto parts are also getting higher and higher. For example, the temperature resistance requirements of rubber parts involved in automobile engines and surrounding areas are increased to 150°C, and ordinary rubber materials cannot meet the requirements.

Abstract

The synthetic composite rubber material is prepared from the following raw materials in parts by mass: 40 to 100 parts of natural rubber, 30 to 60 parts of ethylene propylene rubber, 10 to 27 parts of silicon dioxide coated porous high-silica fiber, 2 to 4 parts of zinc oxide, 2 to 4 parts of maleic acid, 2 to 4 parts of paraffin oil, 60 to 90 parts of carbon black, 2 to 4 parts of anti-aging agent, 2 to 6 parts of sulfur and 0.2 to 2 parts of vulcanization accelerator. The silicon dioxide-coated porous high-silica fiber is a product formed by carrying out directional hydrolysis by taking the high-silica fiber as a template and hexadecyl trimethyl ammonium bromide as a pore-foaming agent and then combining and coating a silicon dioxide aerogel layer on the surface of the high-silica fiber. The invention discloses a preparation method of the synthetic composite rubber material.

Description

Technical field [0001] The present invention relates to the field of rubber composite and technical application, in particular to a synthetic composite rubber material and a preparation method thereof. Background [0002] Rubber composite and use technology, the earliest began in the manufacture of automobile tires, no matter any rubber, it is impossible to have perfect performance, and in reality, the use of the department often put forward a variety of performance requirements for the product, in order to meet this purpose, so that the final product to achieve the performance requirements that are difficult to obtain by a single rubber, or in order to reduce production costs, so the two or more rubber mixed with a technical means. [0003] Rubber composite, not all kinds of rubber can be used at will, some types of rubber belong to the non-phase soluble system, at this time how to ensure that it can be smoothly mixed is a big problem, even if the choice of good compatibility of...
