High-hardness support sealing ring rubber material

Abstract

The invention discloses a high-hardness support sealing ring rubber material, which comprises the following raw materials in parts by weight: 40-60 parts of natural rubber, 40-60 parts of butadiene-styrene rubber, 1.5-3.5 parts of sulfur, 2-4 parts of an accelerant, 3-5 parts of zinc oxide, 1-4 parts of stearic acid, 7-13 parts of tackifying resin, 120-170 parts of general carbon black, 4-8 partsof an anti-aging agent. 1-3 parts of paraffin, 1-3 parts of a dispersing agent, 0.5-2.5 parts of an anti-scorching agent and 2-5 of pine tar; wherein the accelerant comprises an accelerant CZ and an accelerant DM. The rubber material has the advantages of high hardness, favorable sealing performance, high support strength, excellent water resistance, excellent wear resistance and long service life, and can satisfy the requirements for long-term use.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber material for a high-hardness support sealing ring. Background technique [0002] The rubber industry is one of the important basic industries of the national economy. It not only provides daily and medical light industrial rubber products that are indispensable for people's daily life, but also provides heavy and emerging industries such as mining, transportation, construction, machinery, and electronics. Various rubber-made production equipment or rubber parts. [0003] Rubber is the latex extracted from plants such as rubber trees and rubber grasses, and processed to make materials with elasticity, insulation, impermeability to water and air. It is a highly elastic polymer compound. Divided into two kinds of natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from rubber trees, rubber grass and other plants; synthetic rubber is obtained...

Problems solved by technology

In the prior art, traditional synthetic rubber and its products are susceptible to aging due to multiple factors during use, resulting in performance degradation and even affecting use

[0004] For example, when the existing sealing rubber ring is used for sealing water supply and drainage pipes, its wear resistance is poor, and it is prone to damage to pollute the water quality or cause pipeline leakage; at the same time, during long-term use, it will also cause aging The performance is degraded and cannot meet the requirements of the pipeline for the support strength of the sealing rubber ring
