Problems solved by technology

However, according to the design principle of the high-pressure hose, the braided hose of the third layer has no effect when the hose is under pressure, which wastes materials, increases the weight of the hose itself, and reduces the flexibility of the hose.

Abstract

The invention discloses a high-pressure-resisting steam rubber pipe. The high-pressure-resisting steam rubber pipe comprises the following substances in parts by weight: 100 parts of EPDM, 10 to 12 parts of chlorosulfonated polyethylene rubber, 0.5 to 0.8 part of stearic acid, 90 to 100 parts of carbon black, 18 to 20 parts of antimony oxides, 25 to 30 parts of paroline, 2 to 4 parts of resin, 3 to 5 parts of anti-aging agent, 1 to 2 parts of silane coupling agent, 1 to 2 parts of active agent, 1 to 1.2 parts of dispersing agent, 2 parts of vulcanizing agent, 5 parts of assistant cross-linking agent TMPT and 1 to 2 parts of accelerant. The high-pressure-resisting steam rubber pipe is excellent in high pressure steam resistance, good in pressure resistance, soft and good in application effect.

Description

technical field [0001] The invention relates to a rubber, in particular to a high-pressure steam-resistant rubber hose. Background technique [0002] According to the production process, high-pressure oil pipes are mainly divided into high-pressure steel wire braided oil pipes and high-pressure steel wire wound oil pipes. [0003] The structure of steel wire wound hose is mainly composed of inner rubber layer, middle rubber layer, four or more layers of alternately wound steel wire reinforcement layer and outer rubber layer. The inner rubber layer has the function of making the conveying medium withstand pressure and protecting the steel wire from erosion, the outer rubber layer protects the steel wire from damage, and the steel wire (ф0.3-2.0 reinforced layer) layer is the skeleton material for reinforcement. [0004] Steel wire braided hose, the structure of high pressure steel wire braided hose is mainly composed of liquid-resistant synthetic rubber inner rubber layer, m...
