The invention discloses an oil resistance rubber material which comprises the following components in parts by weight: 40-70 parts of AFLAS, 2-4 parts of a vulcanizing agent, 3-6 parts of diethylene glycol, 3-5 parts of stannic oxide, 5-8 parts of polytetrafluoroethylene, 4-6 parts of stearic acid, 2-6 parts of asphalt, 10-12 parts of carbon black N330, and 2-3 parts of rosin. Compared with the prior art, the oil resistance rubber material which is produced according to a rubber formula has excellent oil resistance, heat resistance and gas tightness, has a certain sealing effect during the process of oilfield exploitation, and the loss caused by corrosion to rubber from oily medium is reduced; the rubber material can be applied to the sealing positions of various machineries for oil extraction, so that the exploitation operation is performed smoothly.
Description
technical field [0001] The present invention relates to rubber, in particular to an oil-resistant rubber material for pipe liners. Background technique [0002] The oil resistance of rubber refers to the ability of vulcanized rubber to resist the action of oil. When rubber products are in contact with various oils in the oil field for a long time, the oil can penetrate into the rubber to make it expand or increase in volume; at the same time, the oil medium can extract soluble compounding agents (such as plasticizers) from the vulcanized rubber. agent, anti-aging agent, anti-degradation agent, etc.), resulting in shrinkage or volume reduction of the vulcanizate. Generally, the swelling increases with the contact time of the vulcanized rubber and the oil until the oil is no longer absorbed, and then the volume expansion remains stable, resulting in the expansion of the originally tightly arranged three-dimensional cross-linked network, and the performance of the rubber produ...
