Abstract

The invention belongs to the technical field of rubber and provides high hardness nitrile rubber and a preparation method of the nitrile rubber in order to solve the problem that the existing nitrilerubber sealing material cannot integrate high hardness and wear resistance. The rubber is prepared from nitrile rubber, zinc oxide, stearic acid, an antiager, octyl-phenolic tackifying resin, carbon black, a softener, a valcanizer and an accelerator according to certain proportions. The rubber is reasonable in compounding, gets a comprehensive balance among product serviceability, appropriate processability and cost reduction, fully exerts potentials of the raw materials and assistants, and achieves unification of high-efficiency, low-consumption and high-performance economic and social benefits. The obtained material has the high hardness, good wear resistance, better tensile strength, better tearing strength and a better permanent compression set value. At the same time, processing operability of the rubber is high, a post-treatment procedure of a product is easy, and physical and mechanical properties are best.

Description

technical field [0001] The invention belongs to the technical field of rubber, and in particular relates to a high-hardness nitrile rubber and a preparation method thereof. Background technique [0002] With the increasing application of high-resistance and high-reliability hydraulic supports, the working resistance of hydraulic cylinders (columns, jacks) is increasing, and the requirements for the performance and life of the rubber seal materials are more stringent. During the use of hydraulic reciprocating sealing components, due to the needs of the working environment, in addition to requiring the product to have excellent high pressure resistance, oil resistance and low compression set performance, it is also required to maintain a very good impact resistance under high pressure for a long time and reliable performance. Therefore, the rubber formulation and mixing process is a highly specialized technical work, which must rely on the continuous optimization of the formu...
