preparation example Construction

[0032] The preparation method of the composite material of hydrogenated nitrile butadiene rubber and polyurethane rubber comprises the steps of: masticating and mixing polyurethane rubber and hydrogenated nitrile butadiene rubber until mixed rubber is obtained; wrapping the mixed rubber with rolls, adding carbon black and The plasticizer is mixed; then stearic acid, anti-aging agent, accelerator and vulcanizing agent are added in sequence and mixed; finally polyglycolic acid is added and mixed until the composite material of hydrogenated nitrile rubber and polyurethane rubber is obtained.

[0033] Plastication refers to the process of transforming rubber from a tough and highly elastic state to a soft plastic state by means of mechanical stress. After the rubber is deformed, it cannot return to its original state, or maintain the properties of its deformed state. The molecular weight of raw rubber is closely related to plasticity. The smaller the molecular weight, the greater...

Embodiment 1

[0036] The composite material of hydrogenated nitrile butadiene rubber of the present invention, polyurethane rubber comprises 65 parts of polyurethane rubbers, 35 parts of hydrogenated nitrile butadiene rubbers, 35 parts of carbon blacks, 1.5 parts of dioctyl dicarboxylates, 0.6 parts of stearic acid, methyl-2 - 0.7 parts of mercaptobenzimidazole, 0.7 parts of tetramethylthiuram disulfide, 3 parts of benzoyl peroxide and 25 parts of polyglycolic acid.

[0037] Preparation method: put polyurethane rubber and hydrogenated nitrile rubber on an open mill for mastication, and blend until uniform; adjust the roll distance of the open mill to make the rubber cover the roll, and gradually add carbon black and plasticizer; after completely mixing , add stearic acid, anti-aging agent, accelerator and vulcanizing agent in sequence; after being completely mixed, add polyglycolic acid and blend until uniform.

Abstract

The invention relates to a composite material of hydrogenated nitrile rubber and polyurethane rubber and a preparation method thereof, and belongs to the technical field of rubber. The composite material of the hydrogenated nitrile rubber and the polyurethane rubber comprises the polyurethane rubber, the hydrogenated nitrile rubber, carbon black, a plasticizer, stearic acid, an antiager, an accelerant, a vulcanizing agent and polyglycolic acid. The soluble rubber composite material can directly lose mechanical properties in water or a well fluid and is eventually dissolved or degraded, so thatthe production efficiency is improved and the working cost is reduced; and the dissolution speed is controlled by adjusting the contents of the hydrogenated nitrile rubber and the polyurethane rubber.

Description

technical field [0001] The invention relates to a composite material of hydrogenated nitrile rubber and polyurethane rubber and a preparation method thereof, belonging to the technical field of rubber. Background technique [0002] Rubber Highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under a small external force, and can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and often a large molecular weight, greater than hundreds of thousands. 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 to people's daily life, but also provides various rubber production equipment or rubber parts for heavy industries such as excavation, transportation, construction, machinery, electron...
