Elastomer composite mud absorption rubber tube and manufacturing technique thereof

Abstract

The invention provides an elastomer composite mud absorption rubber tube and the manufacturing technique thereof. The elastomer composite mud absorption rubber tube mainly comprises a mud absorption rubber tube body, cord fabric, a tightening steel wire, a rubber tube outer layer, a steel ring and a flange steel short sleeve, wherein a middle layer is arranged on the inner surface of the cord fabric, the middle layer is made of canvas, a composite layer is arranged on the inner surface of the middle layer, and the composite layer is made of polyurethane materials or polyurea materials. After a rubber tube blank is manufactured, the cast-molding technique or the centrifugal molding technique or the spray-molding technique is adopted to manufacture the elastomer composite mud absorption rubber tube. According to the elastomer composite mud absorption rubber tube and the manufacturing method thereof, due to the elimination of inner glue existing in a current mud absorption rubber tube, the vulcanizing time of the tube blank is shortened; the middle canvas layer single-face rubber lining technique improves the bonding strength between an elastomer and the cord fabric; due to the fact that specialized supports are designed and used in the centrifugal technique and in the spraying technique, the deformation problem of the tube body in a manufacturing process is solved, and the uniformity of the thickness of the composite layer is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a mud suction hose and a production method thereof. Background technique [0002] Existing dredger suction hoses generally use natural rubber as the inner layer glue. Since the dredged soil is transitioning from silt and fine silt to medium-coarse sand, the dredging depth is getting deeper and deeper. The inner rubber of the traditional mud suction hose is severely worn and its service life is significantly shortened, making it difficult to adapt to the current construction requirements. During the construction, the dredging efficiency is often affected due to the damage of the mud suction hose, resulting in a decrease in production efficiency and an increase in production costs. [0003] The existing mud suction hose production process first forms the inner rubber, then assembles the flange steel short sleeve and the cord layer, and finally vulcaniz...

AI Technical Summary

Problems solved by technology

The inner layer of the traditional mud suction hose is severely worn and its service life is significantly shortened, making it difficult to adapt to the current construction requirements

During construction, dredging efficiency is often affected due to damage to the mud suction hose, resulting in reduced production efficiency and increased production costs

[0003] The existing mud suction hose production process first forms the inner layer of glue, then assembles the flange steel short sleeve and the cord layer, and finally vulcanizes. The vulcanization time is long, and there are still problems such as easy deformation of the pipe body during the manufacturing process.

[0004] In order to increase the wear resistance of the rubber hose, wear-resistant materials can be used to replace the inner layer glue, but the bonding strength between the conventional wear-resistant materials and the ply composed of polyester or nylon is very poor, and for soft rubber hoses, there is no mature one at present. Wear-resistant layer forming process, because the tube body is easy to bend and deform when rotating on the centrifuge in the ordinary centrifugal forming or spraying forming process, resulting in uneven thickness of the wear-resistant layer
