Processing method for rubber pipe

Abstract

The invention discloses a processing method for a rubber pipe. The processing method comprises the steps that inner layer rubber, middle layer rubber and outer layer rubber are prepared through mixing of a mixing mill according to the formula; an inner layer rubber pipe is squeezed out through an extrusion machine, and the inner layer rubber pipe coats a soft core or hard core coated with a release agent; the middle layer rubber is pressed into a middle layer rubber sheet through a calendar, a separant is added, the middle layer rubber sheet is rolled, and the rolled middle layer rubber sheet is cut to prescribed width according to the technological requirement; a coppered steel wire or coppered steel wire rope is wound on the inner layer rubber pipe containing the pipe core on a winding machine or knitting machine, the middle layer rubber sheet is synchronously wound between every two layers of coppered steel wires or coppered steel wire ropes on the winding machine or knitting machine, and heads and ends of the winding steel wires are bound; the extrusion machine is coated with the outer layer rubber again, and then is coated with a lead or cloth vulcanization protection layer again; vulcanization is carried out through a vulcanizing tank or salt bath; and finally, the vulcanization protection layer is removed, the pipe core is pulled out, pipe connectors are buckles, and sampling is carried out for bulge test. Compared with the prior art, the method can provide the high-pressure rubber pipe which meets the user requirement.

Description

technical field [0001] The invention belongs to the technical field of rubber hoses, and in particular relates to a rubber hose processing method. Background technique [0002] Hose is a kind of tubular rubber product used to transport gas, liquid, slurry or granular materials. It is composed of inner and outer rubber layer and skeleton layer. The material of skeleton layer can be cotton fiber, various synthetic fibers, carbon fiber or asbestos, steel wire, etc. Generally, the inner and outer rubber layers of the rubber hose are made of natural rubber, styrene-butadiene rubber or butadiene rubber; the oil-resistant rubber hose is made of neoprene and nitrile rubber; the acid and alkali-resistant hoses are made of ethylene-propylene rubber, fluorine rubber or silicone rubber. [0003] The production process of the hose generally includes: batching, banburying, mixing, gluing, extrusion, vulcanization, cutting, packaging and other processes. High-pressure hose is a common ty...
