Abstract

The invention provides rubber sealing materials. The rubber sealing materials are formed by the following components of, by mass, 40 to 45 parts of acrylate rubber, 15 to 20 parts of hydrogenated nitrile-butadiene rubber 15-20, 3 to 5 parts of stearic acid, 0.8 to 1.2 parts of methyl hydrogen silicone oil, 0.5 to 0.8 part of glass fibers, 2 to 3 parts of oleic acid diethanolamine borate ester, 4 to 6 parts of diacetyl peroxide, 2 to 3 parts of aluminum oxide, 1.2 to 1.6 parts of light calcium carbonate, 0.6 to 0.9 part of drying oil alkyd resin, 6 to 8 parts of white carbon black, 0.5 to 2 parts of anti-aging agent and 2 to 3 parts of sulfur. According to the rubber sealing materials, the mechanical strength is high, the friction coefficient which is 0.19 to 0.21 is low, the abrasion resistance is high, and the 140 to 170 days of service life under the high temperature and the high pressure working conditions is long, wherein the rubber sealing materials can work at 200 DEG C and the 420 MPa pressure can be borne.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to a rubber sealing material. 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 sealing material that can be used for a long period of time in ...
