Abstract

A wear-resistant rubber polyurethane compound hose is characterized by comprising a bearing layer (4), a wear-resistant layer (5) and a protective layer (6). The inner wall of a pipeline is formed by the wear-resistant layer (5), the bearing layer (4) is arranged on the outer wall of the wear-resistant layer (5), the protective layer (6) is disposed on the outer layer of the bearing layer (4); the wear-resistant layer (5) is an elastic pipe body formed by pouring polyurethane materials inside a die, and is arranged to be an integral structure with a flange steel ring (1) via a pouring hole on the flange steel ring (1). A circular sealing flanging (7) is disposed outwards on the wear-resistant layer (5) along a flange disk, the bearing layer (4) is formed by weaving more than one layer of cord threads in a cross-intertwining arrangement outside the tube body of the wear-resistant layer (5), and one layer of steel wires is wound on the outer side of a reinforced steel ring (2) at the position of the flange steel ring (1) once every 2-4 layers of cord threads are wound. The wear-resistant rubber polyurethane compound hose has the advantages of fine wear resistant property, scale prevention, low running resistance, fine water resistant property, fine aging resistant property, fine combination and long service life.

Description

technical field [0001] The invention relates to a mud suction and discharge hose used in the dredging industry, specifically a wear-resistant rubber polyurethane composite hose, which is widely used in dredging construction, electric power, coal, mining, building materials, chemical industry and other industries to transport mud Sand, coal powder, ash, aluminum liquid, mud and other abrasive granular materials and corrosive media can also be used as pressure pipes. Background technique [0002] At present, the structure of the mud discharge hose in the prior art is an all-rubber structure. The disadvantage is that the pipe wall is rough, which leads to large internal resistance and high wear in the pipe during use, and shortens the service life of the pipe. Contents of the invention [0003] The purpose of the present invention is to provide a wear-resistant rubber polyurethane composite material that is wear-resistant, acid-resistant, alkali-resistant, anti-scaling, radia...
