Problems solved by technology

[0004] 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
[0005] Moreover, among all kinds of water delivery pipes at present, those using rubber as raw materials cannot be non-toxic, while water delivery pipes using materials such as plastics and metals 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

Embodiment Construction

[0041] Combine below figure 1 The preparation method of the present invention is specifically described.

[0042] In this method, when preparing the water delivery pipe, at first the mandrel is prepared, and the mandrel is used for winding the rubber hose thereon. Before preparing the hose, the mandrel should be cleaned.

[0043] Then prepare the Le Ruigu 1524 release agent, stir the release agent evenly until it becomes a milky white liquid, and coat the prepared Le Ruigu 1524 release agent on the mandrel. The function of the release agent is to wait until the subsequent rubber hose is prepared and shaped, and the mandrel can be taken out of the rubber hose smoothly. Due to the multiple high-temperature processes involved in the preparation of the rubber hose, if no release agent is applied, the subsequent rubber hose will adhere to the mandrel after molding and cannot be taken out. In another implementation manner, peanut oil is used as the release agent.

Abstract

The invention provides a production method of water delivery pipes. The water delivery pipes have the advantages of light pipe bodies, high bending performance, high bearing strength, low deformation, high tensile strength, operation simplicity, convenience in use and stable performance. Inner rubber layers of the water delivery pipes produced by the method are free of toxicity; the safety of the water delivery can be ensured; winding angles of first adhesive tape layers and second adhesive tape layers of the produced water delivery pipes adopt the balance angles of 54 degrees+11 / 15 degree and -54 degrees+11 / 15 degree. Through the adoption of the special winding angles, the produced water delivery pipes are high in bending performance and cannot be broken by bending. The materials of various rubber layers of the water delivery pipes are specially selected, so that the water delivery pipes are high in bending performance and high in tensile strength, and can be bent and unfolded repeatedly; compared with the ordinary water delivery pipes with the same tensile strength of the produced water delivery pipes, the bending performance of the produced water delivery pipes is improved by more than two times.

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 ships or offshore drilling platforms. For ships, it can not only expand the radius of the ship's activities, but more importantly, the ship does not have to go back and forth to obtain its own supplies. [0003] 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. . [0004] However, the current ordinar...
