Abstract
The invention discloses a high-temperature-resistant rubber material. The rubber material is prepared from, by weight, 15-25 parts of fluororubber, 15-25 parts of cis-butadiene rubber, 5-8 parts of carbon black, 2-5 parts of sulfur, 9-15 parts of calcium hydroxide, 6-9 parts of magnesium oxide, 1-5 parts of aluminum nitrate and 1-2 parts of a modifying agent. The high-temperature-resistant rubber material is mainly used for manufacturing industrial seal parts, and compared with an existing material for the seal parts, the rubber material is excellent in high temperature resistance and capable of enduring long-time high-temperature impact and meets the high-temperature requirement of the existing seal parts.
