Rubber sealing material and preparation method thereof

Abstract

The invention discloses a rubber sealing material and a preparation method thereof. The rubber sealing material is prepared from, by weight, 30-50 parts of hydrogenated butadiene-acrylonitrile rubber, 15-35 parts of butadiene styrene rubber, 10-30 parts of raw carboxy nitroso fluororubber, 10-20 parts of polypropylene, 8-18 parts of allyl alcohol, 1-3 parts of barium hydroxide, 8-17 parts of microcrystalline cellulose, 8-15 parts of diacetyl peroxide, 6-14 parts of dioctyl adipate, 0.8-4.5 parts of glass fiber, 3-10 parts of organic montmorillonite, 5-15 parts of nanometer sepiolite powder, 5-12 parts of aluminophosphite, 2-6 parts of calcium ferrite, 3-7 parts of zinc oxide, 5-12 parts of white carbon black, 1-3 parts of an anti-aging agent and 1-5 parts of a vulcanizing agent. The rubber sealing material is high in wear resistance and loading capacity, and the service life of the rubber sealing material is greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of rubber 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 sealing ring bears a large load, and the seals are often damaged during the operation of the equipment. The replacement cycle of the seals is short, which brings troubles to the continuous production of the enterprise. Therefore, there is an urgent need for rubber sealing materials with strong pressure bearing capacity and good wear resista...
