Embodiment 1

[0015] The rubber material used for the fabric sealing ring of the present embodiment is made of 100 parts of natural glue (dry glue) with a glue content of 35%, dry plain cotton canvas with a moisture content of less than 1.0%, and 45 parts by mass fraction. The compounding agent is made; wherein the compounding agent is composed of carbon black, zinc oxide, vulcanization accelerator, stearic acid, vulcanizing agent and anti-aging agent D in a mass ratio of 30:8:1.5:2:2.5:1.

[0016] The natural rubber latex described in this embodiment is a commercially available industrial grade. The vulcanization accelerator is 2-mercaptobenzothiazole, namely accelerator M. The vulcanizing agent is sulfur. The anti-aging agent D is N-phenyl-2-naphthylamine. Described vulcanization accelerator, vulcanization agent and antioxidant D are commercially available.

[0017] The preparation method of the rubber material for the fabric sealing ring by the dipping method in this embodiment is car...

Abstract

A fabric sealing ring material prepared by natural rubber latex dipping method, the raw material components are composed of 100 parts of natural glue (dry glue) with a glue content of 35%~40% according to the mass fraction ratio, and the water content is less than 1.0 % of dry plain cotton canvas, 45~55 parts of compounding agent; wherein the compounding agent is made of carbon black, zinc oxide, vulcanization accelerator, stearic acid, vulcanizing agent and anti-aging agent D in a mass ratio of 30~40:8: 1.5:2:2.5:1 composition. The fabric rubber material of the present invention has a simple preparation process and low cost, and the fabric sealing ring prepared by the natural rubber latex dipping method has good resilience, wear resistance, high mechanical strength, softness and durability, and excellent sealing performance.

Description

technical field [0001] The invention relates to the field of seals, in particular to a natural rubber latex material for fabric sealing rings. Background technique [0002] Sealing ring, also known as O-ring, is an accessory used for sealing and shock absorption. It can not only prevent the leakage of lubricating oil in the bearing part of the rotating shaft, but also prevent the external dust, sand, and muddy water from immersing. Because of its simple structure, good sealing performance and convenient installation, it is widely used in the sealing of diesel locomotives, automobiles, tractors, engineering machinery, machine tools and various hydraulic and pneumatic components. Sealing rings are divided into various models and specifications due to different purposes, and the selection of their materials is also different. In addition to rubber, there are also materials such as polytetrafluoroethylene and polyoxymethylene. But in general, it is mainly divided into two types...
