Abstract

The invention discloses a sealing ring natural rubber material for a water supply and drainage pipeline. The sealing ring natural rubber material is prepared from the following raw materials in partsby weight: 50-70 parts of natural rubber, 70-90 parts of rubber seeds, 0.5-2.5 parts of sulfur, 2-5 parts of an accelerant, 2-6 parts of zinc oxide, 1-3 parts of stearic acid, 3-20 parts of engine oil, 50-70 parts of general carbon black, 3-20 parts of high-wear-resistance carbon black, 4-8 parts of an anti-aging agent, 0.5-2 part of micro-crystalline wax, 2-6 parts of a dispersing agent and 0.3-1part of an anti-scorching agent; wherein the rubber seeds are prepared from the following raw materials in parts by weight: 30-50 parts of butadiene rubber, 3-7 parts of pine tar, 10-15 parts of tackifying resin, 0.5-2 part of stearic acid, 20-30 parts of general carbon black and 3-7 parts of a defoaming agent. The invention also provides a preparation method of the sealing ring natural rubber material.

Description

technical field [0001] The invention relates to the technical field of sealing products, in particular to a natural rubber material for sealing rings for water supply and drainage pipes and a preparation method thereof. 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 tr...
