Embodiment Construction

[0015] The rubber sealing ring proposed by the present invention will be further described in detail below in conjunction with specific embodiments. Advantages and features of the present invention will be apparent from the following description and claims.

[0016] An embodiment of the present invention provides a rubber sealing ring, and the material used for the rubber sealing ring is made of the following raw materials in parts by weight:

[0017] Nitrile rubber: 85; Zinc oxide: 6; Antiaging agent: 2; Stearic acid: 1; High wear-resistant carbon black: 100; MDC sulfur: 3; Accelerator: 1; N-cycloethyl-2-benzene Thiazole sulfenamide: 2.

[0018] The N-cycloethyl-2-benzothiazole sulfenamide in this example is a highly active aftereffect accelerator with excellent scorch resistance, safe processing and short vulcanization time. The promotion effect is very strong when the vulcanization temperature is above 138 °C. Rubber products vulcanized with N-cycloethyl-2-benzothiazole ...

Abstract

The invention provides a rubber sealing ring. The material used by the rubber sealing ring is prepared from the following raw materials, in parts by weight: 80-90 parts of nitrile rubber; 5-7 parts of zinc oxide; 1-3 parts of an anti-aging agent; 0.5-1.5 parts of stearic acid; 90-110 parts of a high abrasion resistant carbon black; 2-4 parts of MDC sulphur; 0.5-1.5 parts of an accelerant; and 1-3 parts of N-cyclohexyl-2-benzothiazolesulfenamide. The rubber sealing ring provided by the invention can meet indicators stated by an SH / T0305-93 standard test method, and increases sealing performance in rubber seal adaptability tests of related petroleum products.

Description

technical field [0001] The invention relates to the field of petroleum product testing, in particular to a rubber sealing ring. Background technique [0002] Because when using petroleum products, the environment they are in is often in contact with the rubber ring of the sealing material of the facility and equipment, so it is necessary to conduct a sealing adaptability test on the petroleum product and its corresponding rubber sealing ring, and in determining the sealing of petroleum products For the adaptability index, the SH / T0305-93 standard test method is required. This method stipulates all the indicators of the rubber sealing ring used in the test of petroleum products, and references the GB / T528 or GB / T531 test method for the application Various indicators of rubber sealing rings used in petroleum product testing are tested. At present, most manufacturers use ordinary rubber sealing rings when conducting related tests on petroleum products. This type of rubber seal...
