Rubber material for seal ring

Abstract

The invention discloses a rubber material for a seal ring. The rubber material is prepared from, by weight parts, magnesium powder, 12-14 parts of micro-encapsulation red phosphorus, 2-3 parts of vulcanizing agent BIPB, 24-27 parts of polyacrylonitrile, 12-13 parts of graphite, 3-4 parts of coal ash microsphere, 0.7-1 part of sodium dodecyl sulfate, 42-55 parts of liquid acrylonitrile butadiene rubber, 0.6-1 part of methacrylic acid, 52-60 parts of acrylonitrile butadiene rubber, 20-25 parts of styrene-butadiene rubber, 3-4 parts of polyethylene wax, 0.2-0.3 part of sodium diacetate, 4-5 parts of polyethylene glycol, 13-15 parts of butadiene styrene rubber, 4-6 parts of manganese powder, 11-13 parts of chalk and 3-4 parts of molybdenum disulfide. The rubber material has very good elasticity, high temperature resistance and aging resistance, has good sealing performance, can serve as various sealing elements, and is good in practicality.

Description

Technical field [0001] The invention relates to the technical field of rubber, in particular to a rubber material for a sealing ring. Background technique [0002] Rubber material is a polymer material that can quickly recover deformation under large deformation. It is one of the important basic industries of the national economy. It provides light industrial rubber products for daily use and medical use, which are indispensable in people's daily life; for mining , Transportation, construction, machinery, electronics and other heavy industries and emerging industries provide a variety of rubber production equipment or rubber parts, which are widely used. In recent years, the rapid development of the rubber industry has put forward higher requirements for rubber products, and rubber materials must develop in the direction of functionalization, refinement and diversification. The traditional single rubber material can no longer fully meet the rapidly developing use requirements. ...

The most traditional reinforcing agents in the rubber industry have always been carbon black and white carbon black. Although they have a certain reinforcing effect, both of these two reinforcing agents have very low apparent densities. When they are added to rubber, they are easily produced. Feiyang, heavy processing pollution, long processing time, high energy consumption for mixing, and the carbon black reinforced product is a single black color, and these two reinforcing agents are difficult to endow the product with higher hardness and better air resistance sex etc.

[0003] Graphite is a layered material with excellent lubricating properties and a very high shape factor in the exfoliated state. Graphite is one of the materials with the highest specific strength and has unique functional properties such as electrical conductivity and thermal conductivity. And the cost is low. As a reinforcing material for rubber, it can improve its tribological properties. However, due to the inert nature of the graphite material itself and the Van der Waals force between the layers, directly adding it to the rubber will greatly reduce its mechanical properties and shorten the service life.
