Abstract

The invention relates to the field of manufacturing anindoor hose in a household natural gas pipeline, in particular to a preparation method of a rubber hose non-metal material used in anti-solvent type (methane type) medium. The novel household fuel gas hose has a multilayer composite structure which consists of an inner layer (1), a middle layer (2) and an outer layer (3), the three layers are respectively formed by mixing the following compositions in parts by weight: the inner layer (1): 30-100 parts of epichloro-hydrin rubber, 0-70 parts of nitrile butadiene rubber, 10-200 parts of filling reinforcing agent, 0.5-40 parts of vulcanizing agent, 0.5-20 parts of accelerant, and other processing aids; the middle layer (2): 100 parts of nitrile butadiene rubber, 10-200 parts of filling reinforcing agent, 0.5-20 parts of vulcanizing agent, 0.5-20 parts of accelerant, and other processing aids; the outer layer (3): 10-100 parts of chloroprene rubber, 0-90 parts of chlorinated polyethylene, 10-200 parts of filling reinforcing agent, 0.5-20 parts of vulcanizing agent, 0.5-20 parts of accelerant, and other processing aids. The obtained rubber hose is good in physical and mechanical properties, good in airtight property, and good in fuel gas corrosion resistance, pressure resistance and thermal stability, and the service life of the rubber hose can be prolonged.

Description

technical field [0001] The invention relates to the field of indoor hose manufacturing in domestic natural gas pipelines, in particular to a non-metallic hose material used in solvent-resistant (methane) media. Background technique [0002] With the sustained and rapid development of my country's national economy in recent years, the demand for energy is also increasing year by year. As a new clean energy, natural gas has played a very good role in adjusting my country's energy structure, improving environmental pollution, facilitating people's lives, saving energy and reducing environmental pollution. Correspondingly higher requirements are put forward for household gas hoses. The fabric-reinforced PVC composite pipes commonly used in the gas industry currently have disadvantages: long-term use of the hose will age and harden, the airtightness will decrease, and safety problems such as gas leakage will easily occur. Contents of the invention [0003] The object of the p...
