Abstract

The invention discloses an environment-friendly oil-resistant rubber sealing piece and a preparation process thereof. The sealing piece is prepared from the following raw materials: natural rubber, nitrile rubber, silicon rubber, butylene succinate, p-t-octylphenol formaldehyde resin, calcium stearate, L-lysine diisocyanate, crylic acid-acrylonitrile copolymer, ethylene-octylene-alkadiene terpolymer, spraying carbon black, copper ammonia fibers, ethylene glycol salicylate, tea-seed oil acid, tetrachlorophthalic acid dioctyl phthalate, tri-n-butyl citrate, an aluminate coupling agent, dicumyl peroxide, 2,4-DCBP, zinc dibutyl dithiocarbamate, zinc oxide, N-octyl N-octadecyl sulfo-amino MoDDC and butyl acetate. The rubber sealing piece provided by the invention is high in oil resistance and comprehensive mechanical property, green and environment-friendly, and is very suitable for being used as the rubber sealing piece widely applied to various fields.

Description

technical field [0001] The invention belongs to the technical field of rubber, and in particular relates to an environment-friendly and oil-resistant rubber seal and a preparation process thereof. Background technique [0002] Seals are one of the important basic components of mechanical equipment, which play the role of leak prevention and sealing. The quality of seals is closely related to the operational reliability, service life and safety of mechanical equipment. As the application fields of seals become more and more extensive, the requirements for their various performance indicators are getting higher and higher. In addition to requiring good sealing effects, environmental protection, oil resistance, heat resistance, wear resistance and adaptability must also be taken into account. The hardness can protect the ecological environment, and at the same time, it can prolong the service life of the seals, avoid various losses, troubles or accidents caused by the damage o...
