Abstract

The invention discloses a high-pressure rubber hose. The high-pressure rubber hose comprises an inner rubber layer, a frame layer and an outer rubber layer, which are tightly stacked together from inside to outside. When the inner rubber layer is prepared, various components are matched according to corresponding weight parts and then smelted in a smelting machine, after smelting, rubber is discharged under the condition of 220 degrees Centigrade, then 1.5 parts of trithiocyanuric acid and 2 parts of sulfur are added for mixing. After mixing, the rubber is extruded at the temperature of 300 degrees Centigrade to obtain the inner rubber layer; when the outer rubber layer is prepared, various components are matched according to corresponding weight parts and smelted in the smelting machine and then added with 1.8 parts of sulfur for mixing and are extruded after mixing to obtain the outer rubber layer. The high-pressure rubber hose can overcome defects of complicated structure, poor corrosion resistance, short service life and the like in the prior art and has the advantages of simple structure, high corrosion resistance and long service life.

Description

technical field [0001] The invention relates to the technical field of rubber hoses, in particular to a high-pressure rubber hose. Background technique [0002] A type of tubular rubber product used to convey gas, liquid, slurry or granular materials. It is composed of inner and outer rubber layers and a skeleton layer. The material of the skeleton layer can be cotton fiber, various synthetic fibers, carbon fiber or asbestos, steel wire, etc. Generally, the inner and outer rubber layers of rubber hoses are made of natural rubber, styrene-butadiene rubber or butadiene rubber; oil-resistant hoses are made of neoprene and nitrile rubber; acid-resistant and high-temperature resistant hoses are made of ethylene-propylene rubber, fluorine rubber or silicone rubber. [0003] There are many types of rubber hoses, and the unified naming method is based on different materials, structures, and uses. The full name of the product is: material + structure (process) + use + rubber hose. ...
