Problems solved by technology

[0003] Usually the rubber itself is not fire-resistant, but in current fire accidents, wires and cables are not fire-resistant and flammable in case of fire. This field lacks a kind of fire-resistant rubber, which is required to play a certain protective role in the fire and reduce the electricity in the fire. The loss brought to people, reduce the harm of electricity, and because the cables and wires are exposed to room temperature for a long time, the sun and rain will cause the cable skin to corrode, age, become hard and inelastic, etc. Therefore, it is necessary to improve a Flame-retardant and corrosion-resistant rubber materials are technical problems that need to be solved at present

Abstract

The flame-retardant and corrosion-resistant rubber material is prepared from the following raw materials in parts by weight: 60 to 100 parts of natural rubber, 30 to 40 parts of chloroprene rubber, 10 to 15 parts of composite fiber, 5 to 10 parts of modified graphene oxide, 5 to 8 parts of polystyrene, 1 to 2 parts of vulcanizing agent, 2 to 4 parts of stearic acid, 3 to 5 parts of zinc oxide, 3 to 5 parts of anti-aging agent, 10 to 15 parts of paraffin and 1 to 3 parts of accelerant. The invention also discloses a preparation method of the flame-retardant corrosion-resistant rubber material; the natural rubber has good elasticity, cold resistance, wear resistance and electrical insulating property, but has poor aging resistance, medium resistance and flame retardance, and the chloroprene rubber has excellent heat aging resistance, ozonization resistance and weather aging resistance. Therefre, the flame-retardant corrosion-resistant rubber material combines the advantages of the two kinds of rubber, wherein by adding the composite fiber and the modified graphene oxide, the rubber material is endowed with excellent flame retardance, corrosion resistance, impact resistance and the like.

Description

Technical field [0001] The present invention belongs to the manufacture of rubber material, and in particular, to a flame retardant corrosion-resistant rubber material and a preparation method thereof. Background technique [0002] The rubber has a high-elastic polymer material that is reversible, elastic at room temperature, which can produce a large deformation under small external force, and can restore the original. Rubber belongs to a complete amorphous polymer, and its glass transition temperature (Tg) is low, the molecular weight is often large, greater than 15,000. The rubber is a high-elastic polymer having a chain shape, a molecular chain has a high flexible, rubber molecular chain crosslinked (vulcanization), cross-linking material, and has a rapid recovery ability And have good physical mechanical properties as well as chemical stability. Rubber is only crosslinking to become a high-elastic material having a value of use, commonly known as the rubber. Rubber is the ba...
