Rubber hose and preparation method thereof

Abstract

The invention discloses a rubber hose. The rubber hose is prepared from, by weight, 30-50 parts of butadiene styrene rubber, 25-50 parts of nitrile rubber, 8-15 parts of white carbon black, 3-10 parts of polyisobutene, 1-5 parts of aluminum sulfate, 2-6 parts of glass powder, 5-10 parts of alkyd resin, 0.5-2 parts of a sulfurizing agent, 20-30 parts of xylene and 0.5-1 part of a crosslinking agent. A preparation method of the rubber hose comprises the steps that the raw materials are weighed by weight of parts, and all the raw materials are arranged in an ultrasonoscope for mixing, then shifted into a mixing mill for extrusion molding and finally molded. The rubber hose is high in mixing efficiency and high in shock resistance and corrosion resistance, and a hose body is solid and durable in use.

Description

technical field

[0001] The invention relates to the technical field of rubber pipes, in particular to a rubber hose and a preparation method thereof. Background technique

[0002] The rubber hose is made of multi-layer rubber, metal and non-metal through a special process. Because of the physical and chemical properties of the inner rubber layer, the effect of the pipeline conveying medium on the pipeline, such as friction, impact, corrosion, etc., is reduced. Moreover, the rubber hose has the characteristic of being bendable, so it has been widely used in the special working conditions of mine beneficiation and transportation. However, during the use of the rubber hose, it is prone to cracks after being exposed to wind and sun. Contents of the invention

[0003] One of the objects of the present invention is to provide a rubber hose, which can solve the problem of short service life of existing rubber hoses.

[0004] In order to solve the above problems, the technical so...
