Abstract

The invention discloses a high-elasticity rubber ring convenient for secondary forming. The high-elasticity rubber ring comprises an upper half part and a lower half part which are formed through mutual pressure casting; reinforcing ribs are arranged between the upper half part and the lower half part; one or more extending ribs are annularly distributed on the lower surface of the upper half part; and limiting grooves matched with the extending ribs are formed in the upper surface of the lower half part. The upper half part is prepared from the following raw materials in parts by weight: 120-125 parts of ethylene propylene diene monomer, 50-60 parts of acrylonitrile, 10-15 parts of carbon black, 15-20 parts of recycled rubber ring powder, 3-5 parts of fatty acid, 3-5 parts of a plasticizing softener, and 8-10 parts of an anti-aging agent. The lower half part is prepared from the following raw materials in parts by weight: 20-30 parts of chloroprene rubber, 30-40 parts of recycled rubber ring powder, 12-13 parts of sodium hexadecyl sulfonate, 8-15 parts of calcium hexadecyl sulfonate, 15-24 parts of cyclohexylthiophthalimide, 3-5 parts of silicon chloride; and 11-15 parts of a carbon black filler. The overall strength and elasticity are improved.

Description

technical field [0001] The invention relates to the technical field of rubber rings, in particular to a high-elastic rubber ring that is convenient for secondary molding. Background technique [0002] Rubber can generally be divided into two categories: synthetic rubber and natural rubber, both of which have a considerable number of applications and products, such as tires, gaskets, etc. Among them, the rubber ring is mostly used in the sealing or buffering field, especially the 0-type rubber ring is widely used in the air pressure or hydraulic sealing occasions. [0003] The current rubber rings are generally formed at one time, resulting in poor overall strength, and the overall elasticity of the final product prepared from the current rubber ring materials is poor, so improvement is needed. Contents of the invention [0004] The purpose of the present invention is to provide a high-elasticity rubber ring that is convenient for secondary molding, so as to solve the prob...
