Abstract

The invention discloses a rubber sealing composite material and a preparation method of the rubber sealing composite material. The rubber sealing composite material comprises the following componentsin parts by mass: 50 to 80 parts of chloroprene rubber, 20 to 30 parts of vinyl silicone resin, 30 to 50 parts of fluorine ether-modified nitrile rubber, 40 to 60 parts of low-polymerization polyethylene, 5 to 12 parts of carbon fibers, 3 to 7 parts of trimethylsiloxane, 3 to 8 parts of nano-silicon nitride, 1 to 3 parts of tert-butyl peroxybenzoate, 5 to 9 parts of benzoic acid amine, 2 to 7 parts of calcium oxide, 3 to 9 parts of nano-silica, 1 to 3 parts of stannous octoate, 6 to 12 parts of diacetyl peroxide. 3 to 7 parts of white carbon, 1 to 3 parts of an antioxidant, 2 to 5 parts of sulfur, 0.8 to 1.8 parts of zinc stearate, and 1 to 5 parts of a coupling agent. Compared with the prior art, both aging resistance and fatigue resistance of the rubber sealing composite material are greatly enhanced, and service performances of the of the rubber sealing composite material are improved effectively.

Description

technical field [0001] The invention belongs to the field of material technology, in particular to a rubber sealing composite material and a preparation method thereof. Background technique [0002] 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. Especially in an environment with high working pressure, the seal ring bears a large load, and the seals are often damaged during the operation of the equipment. Some seals can only be used for 1-2 months, or even a shorter time , it needs to be replaced, which brings troubles to the continuous production of the enterprise. Therefore, there is an urgent need for a rubber sealing composite materia...
