Abstract
The invention relates to a thermoplastic sealed rubber material which is prepared from the following raw materials in parts by weight: 25-40 parts of fluororubber, 15-22 parts of hydrogenated butyronitrile rubber, 4-7 parts of hydroxyl silicone oil, 6-9 parts of magnesium oxide, 10-15 parts of highly wear resistant carbon black, 1-4 parts of hypalon-20, 2-5 parts of sulfur, 9-15 parts of oleyl alcohol and 9-16 parts of a plasticizer. The material provided by the invention has the beneficial effects that the rubber material is good in plasticity and stable in sealing performance, can be used for resisting high temperatures and high pressures, and is suitable for various sealing elements.
Description
technical field [0001] The invention relates to a thermoplastic sealing rubber material, which belongs to the technical field of rubber. Background technique [0002] There are more large and small rubber products required by the industrial sector, with many varieties and wide uses, and some have special requirements. The main products are tapes, rubber hoses, sealing gaskets, rubber rollers, rubber sheets, rubber linings and labor protection products. Sealing products are important basic components of all kinds of machinery, and almost all industrial sectors cannot do without it. The quality of the sealing element is directly related to the service life and operational reliability of the machine. If the quality of the seals is poor, it will cause loss and trouble if it is light, and it will cause serious accidents if it is serious. In an environment with high working pressure, the sealing ring bears a large load, which requires the sealing product not only to have good s...
