A kind of preparation method of water delivery pipe

Abstract

The invention provides a method for preparing a water delivery pipe. The product of the invention has the advantages of light pipe body, good bending performance, high bearing strength, small deformation, high tensile strength, simple operation, convenient use, stable performance and the like. The inner rubber layer of the water delivery pipe prepared by the invention has no toxicity and can ensure the safety of water delivery. The winding angles of the first adhesive plaster layer and the second adhesive plaster layer of the water delivery pipe prepared by the present invention adopt balance angles of 54°44' and -54°44'. By adopting this special winding angle, the water delivery pipe prepared by the present invention has very good bending performance and will not be bent due to bending. The present invention also uniquely selects the material of each adhesive layer, which can not only achieve good bending performance, but also have high tensile strength, and can realize repeated bending and unfolding. Its bending performance is more than twice that of ordinary water pipes with the same tensile strength.

Description

technical field [0001] The invention relates to the field of rubber product preparation, in particular to a method for preparing a water delivery pipe. Background technique [0002] The implementation of replenishment at sea is a means of maritime logistics support that is often required for maritime operations. It can be applied to various occasions such as offshore drilling platforms. In the process of recharge at sea, fresh water transportation is a very important part of the recharge process. Since there must be a large distance between the two ships when fresh water is transported between ships, and hoses must be used, therefore, there are very high requirements for the tensile strength, non-toxicity and bending radius of the water delivery pipes. . [0003] However, the current ordinary water pipes are either difficult to meet the requirements for tensile strength, or have poor UV resistance. Moreover, under normal circumstances, there is an inverse relationship be...

Problems solved by technology

[0003] However, the current ordinary water pipes are either difficult to meet the requirements for tensile strength, or have poor UV resistance.

Moreover, under normal circumstances, there is an inverse relationship between the tensile strength and the bending radius, that is to say, if you want to increase the tensile strength, the bending radius will be very large, which is extremely inconvenient to use, and if you want to obtain A small bending radius tends to reduce the tensile strength

[0004] Moreover, among various water delivery pipes at present, the water delivery pipes using rubber as raw materials cannot be non-toxic, and the water delivery pipes using plastic, metal and other materials obviously cannot meet the requirements of water transportation.

Therefore, there is not a kind of tensile, nontoxic, and easy-to-use water pipe in the prior art that can adapt to the requirements of large-scale replenishment at sea
