Problems solved by technology

[0002] In dredging projects such as harbors, rivers, and lakes, most dredgers pump out the sediment, and the discharge and suction pipes used with dredgers are more and more widely used. Most of the current discharge and suction pipes are made of metal steel pipes, cement Pipes, etc., due to the nature of their materials, the row of mud suction pipes has shortcomings such as not easy to bend, easy to corrode, and not wear-resistant. In this way, not only the construction is inconvenient, but also its service life is short, and the cost is greatly increased.
And it is applied to the sewage pipe, because the sewage is alkaline or acidic, the corrosion of the suction pipe will be greater

Abstract

The invention belongs to the technical field of hoses and manufacturing method thereof and discloses a mud suction and drainage hose and the preparation method thereof. The hose is mainly characterized in that the hose comprises an internal glue layer, an external glue layer and flanges at both ends; an enhancement layer is installed between the internal glue layer and the external glue layer; theinternal glue layer comprises the following materials according to parts by weight: 75 parts of natural rubber, 25 parts of styrene-butadiene rubber, 4-8 parts of zinc oxide, 3-5 parts of stearic acid, 50-80 parts of carbon soot, 1-2 parts of sulfur, 0.5-2.0 parts of accelerant CZ,10-20 parts of pine tar, 15-30 parts of fine particle calcium carbonate, 1.0-2.0 parts of paraffin, 1.0-2.0 parts ofage inhibitor A and 5-10 parts of coumarone, the external glue layer comprises the following materials according to parts by weight: 60 parts of natural rubber, 40 parts of styrene-butadiene rubber,5-10 parts of zinc oxide, 3-5 parts of stearic acid, 40-60 parts of carbon soot, 1-2 parts of sulfur,1.0-2.0 parts of accelerant DM, 10-20 parts of pine tar, 60-90 parts of fine particle calcium carbonate,1.0-2.0 parts of paraffin and1.5-2.5 parts of age inhibitor A. Cord fabric is used and spirally intertwined between the internal glue layer and the external glue layer according to a degree ranging from 52 degrees to 57 degrees. Pressive strength and aging resistant performance are improved.
