High-strength flame-retardant rubber material

Abstract

The invention discloses a high-strength flame-retardant rubber material. The high-strength flame-retardant rubber material is prepared from the following raw materials by weight: 2 to 3 parts of diphenylsilanediol, 4 to 5 parts of melamine, 1 to 2 parts of microcrystalline cellulose, 16 to 20 parts of husk ash, 2 to 3 parts of antioxidant AW, 1 to 2 parts of di-t-butyl peroxide, 24 to 27 parts of polyacrylonitrile, 12 to 13 parts of graphite, 3 to 4 parts of fly ash bead, 0.7 to 1 part of sodium dodecyl sulfate, 42 to 55 parts of liquid butadiene-acrylonitrile rubber, 0.6 to 1 part of methacrylic acid, 52 to 60 parts of butadiene-acrylonitrile rubber, 20 to 25 parts of butadiene styrene rubber, 8 to 9 parts of polyphenyl granule, 2 to 4 parts of magnesium oxide and 13 to 17 parts of heavy calcium carbonate. The rubber material provided by the invention has good tensile properties, wear properties and flame retardant properties; and production of the material is low in cost and easy to implement.

Description

technical field [0001] The invention relates to the technical field of rubber, in particular to a high-strength flame-retardant rubber material. Background technique [0002] Rubber material is a polymer material that can quickly recover from 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 that 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 ...

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.
