Abstract

The invention discloses a reciprocating-motion rubber sealing ring and a production technology thereof. The reciprocating-motion rubber sealing ring is prepared by mixing the following raw materials: 95-100 parts of butadiene nitrile rubber, 8-10 parts of zinc oxide, 3-5 parts of stearic acid, 1-3 parts of an antioxidant 4010, 3-5 parts of paraffin, 45-50 parts of a carbon black N660, 2-4 parts of dibutyl phthalate, 0.3-0.5 part of sulphur and 1-1.2 parts of a promoter TMTD. The production technology is reasonable, various raw materials are mixed uniformly and a uniformly-mixed product is obtained. The reciprocating-motion rubber sealing ring has the advantages of aging resistance, liquid resistance, good tensile strength and elongation, no phenomena of wearing and oil leakage, steady product quality, long service life and the like.

Description

technical field [0001] The invention relates to the technical field of rubber products, in particular to a reciprocating rubber sealing ring and its production process. Background technique [0002] With the development of industry, the application of seals is becoming more and more extensive. Usually, the production of rubber seals adopts the method of molding with fixed specifications. [0003] Reciprocating rubber sealing rings are widely used for sealing pistons in reciprocating hydraulic cylinders. However, the reciprocating rubber sealing products made according to the traditional process have poor oil resistance, liquid resistance, aging resistance, low elongation and low tensile strength, resulting in low production efficiency. Contents of the invention [0004] The purpose of the present invention is to provide a reciprocating rubber sealing ring and its production process. The new mixing process technology is adopted to make the process more reasonable, and the ...
