Abstract

The invention discloses a sealing ring rubber material and a preparation method thereof. The sealing ring rubber material is prepared from the following raw materials in parts by weight: 35-60 parts of cis-polybutadiene, 20-35 parts of a chloroprene rubber adhesive, 20-40 parts of natural rubber, 10-25 parts of trimellitic acid triene propyl ester, 3-8 parts of trioctyl phosphate, 3-12 parts of ammonium polyphosphate, 5-11 parts of triallyl cyanuric acid ester, 2-6 parts of dicumyl peroxide, 3-7 parts of nano calcium carbonate, 2-7 parts of boric oxide, 1-5 parts of coumarone, 4-9 parts of nano calcium oxide, 1-5 parts of sulfur, 3-8 parts of aluminum hydroxide, 3-6 parts of zinc borate, 5-9 parts of tricalcium silicate, 2-6 parts of strontium carbonate and 2-5 parts of an anti-aging agent. The sealing ring rubber material disclosed by the invention is good in aging resistance and long in service life, thereby meeting relatively high sealing requirements.

Description

technical field [0001] The invention belongs to the technical field of rubber materials, in particular to a sealing ring rubber material and a preparation method thereof. Background technique [0002] Rubber has good comprehensive properties, such as high adhesion to metal, mechanical properties, fatigue properties, aging resistance, and low heat generation. Rubber sealing rings are used in various industries. At present, due to the poor aging resistance of the rubber sealing ring, the service life of the sealing ring is greatly shortened, and its performance is difficult to improve. With the continuous improvement of people's quality requirements for the rubber sealing ring, there is an urgent need for an anti-aging Aged rubber seal material. Contents of the invention [0003] The object of the present invention is to provide a sealing ring rubber material and a preparation method thereof. The sealing ring rubber material has good aging resistance and long service life. ...
