Abstract

The invention discloses an O-shaped rubber sealing ring and a production technology thereof. The O-shaped rubber sealing ring is prepared by mixing the following raw materials: 95-100 parts of butadiene nitrile rubber, 10-15 parts of zinc oxide, 3-5 parts of stearic acid, 1-3 parts of an antioxidant 4010, 3-5 parts of paraffin, 5-7 parts of a carbon black N660, 8-10 parts of a coumatone resin, 1-2 parts of an antioxidant RD, 7-9 parts of a fluorescent whitening agent CBS, 2-4 parts of dibutyl phthalate, 2-3 parts 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 O-shaped rubber sealing ring has 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 an O-shaped rubber sealing ring and a production process thereof. 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] O-shaped rubber sealing rings are widely used in various machinery, resistant to various petroleum base oils and various chemical media. [0004] The original rubber sealing products adopt the traditional production process. The rubber material is cut and carved with scissors or blades after being unloaded by the kneading machine, and then overlapped into the mold for vulcanization, thereby making an O-shaped rubber sealing ring. The rubber sealing products have poor oil resistance, liquid resistance, aging resistance, low elongation and low tensile strength, resulting in low pro...
