Abstract

The invention relates to a rubber seal material formula which comprises 25 parts of hydrogenated nitrile-butadiene rubber, 70 parts of chloroprene rubber, 50 parts of acrylate rubber, 20 parts of silicon rubber, 30 parts of polyurethane rubber, 3 parts of plasticizer, 2 parts of softening agent dioctyl ester, 2 parts of activator zinc oxide, 1 part of oleyl alcohol, 9 parts of sulfur, 1 part of diacetyl peroxide, 2 parts of hydroxy silicon oil, 2 parts of alumina, 8 parts of flame retardant and 2 parts of anti-aging agent sulfydryl benzimidazole. Compared with the prior art, the rubber seal material provided by the invention can bear higher pressure, has the advantages of low friction factor and high abrasion resistance; and more scientific and reliable proportioning is performed in the vulcanization system and filler system to better display the synergistic action and prolong the normal working time of mechanical equipment.

Description

[0001] technical field [0002] The invention relates to a chemical product, in particular to a rubber sealing material formula. Background technique [0003] 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. The lubrication system widely used in metal smelting machinery and equipment contains acid and alkali, which has obvious penetration force on rubber seals, causing rubber parts to swell and unable to seal, affecting normal equipment operation. If the quality of the seal is poor, it will cause loss and trouble if it is light, and it will cause serious accidents if it is serious. This requires that the sealing product not only has good sealing performance, but also has good high pressure resistance. Contents of the invention [0004] The technical problem to be solved by ...
