Rubber sealing ring

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...
