Novel hydraulic material for engineering machinery and processing process of novel hydraulic material

Abstract

The invention provides a novel hydraulic material for engineering machinery. The novel hydraulic material is prepared from the following raw materials in parts by weight: 80-100 parts of acrylic nitrile rubber, 20-40 parts of carbon black, 5-7 parts of a plasticizer, 7-9 parts of aluminum oxide, 1.5-1.9 parts of stearic acid, 8-18 parts of a hardening agent, 8-17 parts of an antioxidant, 4-8 parts of an anti-aging agent, 1.5-2.3 parts of a vulcanizing agent and 30-50 parts of an adjuvant ED, wherein the adjuvant ED is prepared from the following raw materials in parts by weight: 4-8 parts of a crosslinking agent, 0.5-3 parts of a peroxide vulcanizing agent and 30-50 parts of carbon black. The novel hydraulic material is prepared from the following raw materials in parts by weight: 90 parts of acrylic nitrile rubber, 50 parts of carbon black, 5 parts of a plasticizer, 7 parts of aluminum oxide, 3 parts of stearic acid, 50 parts of a hardening agent, 20 parts of an antioxidant, 2 parts of an anti-aging agent, 2 parts of a vulcanizing agent and 40 parts of an adjuvant ED, wherein the adjuvant ED is prepared from the following raw materials in parts by weight: 4-8 parts of a crosslinking agent, 0.5-2.5 parts of a peroxide vulcanizing agent and 30-40 parts of carbon black. The novel hydraulic material has the beneficial effects that according to the woven inner glue fabricated by the novel material disclosed by the invention, the crosslinking degree is increased, the tensile strength is increased, the heat resistance and the oil resistance are improved, and thus the product quality is improved.

Description

technical field [0001] The invention relates to a construction machinery material, in particular to a new construction machinery hydraulic material. Background technique [0002] In recent years, the construction machinery industry has put forward higher requirements on the quality of hydraulic hoses for construction machinery, especially the performance of heat-resistant oil.
