Rubber sealing material and preparation method thereof

Abstract

The invention discloses a rubber sealing material. The rubber sealing material is prepared from components in parts by mass as follows: 45-70 parts of chloroprene rubber, 12-22 parts of melamine, 10-20 parts of trimethyl siloxane, 3-6 parts of nano calcium phosphate, 4-8 parts of ammonium benzoate, 3-8 parts of calcium oxide, 15-30 parts of acrylate rubber, 0.5-0.9 parts of stannous octoate, 5-10 parts of allyl alcohol, 7-12 parts of diacetyl peroxide, 4-9 parts of zinc oxide, 0.6-1.5 parts of an anti-aging agent, 3-5 parts of sulfur, 2-7 parts of vinyl silicone resin, 0.6-1.5 parts of zinc stearate, 5-9 parts of glycerol triacetate, 4-9 parts of maleic anhydride, 3-8 parts of dodecylbenzene sulfonic acid, 3-6 parts of calcium propionate and 0.3-0.8 parts of a coupling agent. Compared with the prior art, the rubber sealing material is high in abrasion resistance and high-temperature resistance and can bear relatively high pressure, and the service life of the rubber sealing material can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of materials, in particular to a rubber sealing 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 material that can be used f...
