The invention discloses a multi-lip rubber sealing ring which comprises the following components in parts by mass: 58-62 parts of nitrile rubber 2845, 38-42 parts of nitrile rubber 230, 3-7 parts of zinc oxide A2O-805, 1.1-1.5 parts of stearic acid SA1840, 0.8-1.2 parts of #80 microcrystalline wax, 1.3-1.7 parts of a first anti-aging agent, 0.8-1.2 parts of a second anti-aging agent, 1.3-1.7 parts of a vulcanizing agent, namely odorless DCP, 2.8-3.2 parts of graphite powder, 33-37 parts of carbon black 550, 18-22 parts of kieselguhr, 13-17 parts of spray carbon black, 14-18 parts of a plasticizer, namely TP759, 1.6-2.0 parts of an internal releasing agent, namely LTM-A, 2.3-2.7 parts of molybdenum disulfide, 4-8 parts of white carbon black and 1.0-1.4 parts of an activating agent. The invention discloses the multi-lip rubber sealing ring which is good in sealing property, has good sealing properties, thermal resistance, abrasion resistance and aging resistance of conventional multi-lip rubber sealing rings and is easy to mold in vulcanization processing, and inferior-quality product defects can be reduced.
Description
【Technical field】 [0001] The invention relates to the technical field of multi-lip sealing rings, in particular to the technical field of multi-lip rubber sealing rings. 【Background technique】 [0002] The multi-lip rubber sealing ring is a composite rubber seal with more than two sealing lips. It is generally used as a mechanical component for sealing grease. The multi-lip rubber sealing ring isolates the parts that need to be lubricated from the output parts in the transmission parts, so as not to let the lubricating oil seep. leak. The multi-lip rubber sealing ring has good sealing performance, long service life, heat resistance, wear resistance, aging resistance, simple structure, easy disassembly, and convenient inspection, but the multi-lip rubber sealing ring is often not easy to form during vulcanization, resulting in a defective rate very high. 【Content of invention】 [0003] The purpose of the present invention is to solve the problems in the prior art, and pro...
