Problems solved by technology

During the use of traditional rubber pads, when the temperature exceeds a certain range, it will cause thermal cracking of the rubber, resulting in a sharp decrease in the performance of the rubber pad and greatly shortening its service life.
Therefore, there is an urgent need to study a rubber mat with good high temperature resistance to solve the aging problem of rubber mats caused by high temperature resistance.

Abstract

The invention discloses a high temperature-resistant rubber pad. The weight ratio of each component is 60-80 parts of nitrile rubber, 5-10 parts of polyacrylonitrile carbon fiber, 10-15 parts of nano-zinc oxide, and 2-2 parts of nano-graphite powder. 5 parts, 1~2 parts of accelerator, 3~5 parts of carbon black, 1~2 parts of stearic acid, 2~5 parts of calcium carbonate, 1~2 parts of rare earth and 2~4 parts of metal cobalt, of which rare earth and metal cobalt The weight ratio is 1:2. The high temperature-resistant rubber mat obtained by the present invention has high heat resistance and excellent mechanical properties. After testing, the high-temperature-resistant rubber mat can work at high temperature for a long time, and its service life is doubled compared with traditional rubber mats. above.

Description

technical field [0001] The invention relates to a high temperature resistant rubber mat and a preparation method. Background technique [0002] Rubber mats will inevitably age during use. There are many factors for the aging of rubber mats, including oxidation, and the combined action of heat and oxygen is extremely common. Within a certain temperature range, heat can promote oxidation. During the use of traditional rubber pads, when the temperature exceeds a certain range, the rubber will be thermally cracked, resulting in a sharp decrease in the performance of the rubber pad, and greatly shortening its service life. Therefore, there is an urgent need to study a rubber mat with good high temperature resistance to solve the aging problem of the rubber mat due to low temperature resistance. Contents of the invention [0003] The object of the present invention is to provide a high temperature resistant rubber mat and a preparation method in order to solve the above-mention...
