Embodiment Construction

[0016] will now refer to figure 1 Preferred embodiments of the present invention will be described in detail.

[0017] see figure 1 ,in figure 1 The upper left part is an enlarged cross-sectional view of a multi-layer wound rubber straight pipe with a polyester film 5 as a coating layer. A hot air vulcanization process for a multi-layer wound rubber straight pipe with a polyester film 5 as a coating layer includes the following step:

[0018] I. Form a rubber tube of corresponding size and specification on the hard mold core 1, and fix the hard mold core 1 and the rubber tube on the machine;

[0019] II. Coating the pre-prepared polyester film 5 from one end of the rubber tube and the hard mold core 1;

[0020] III. Put the coated rubber tube and the hard mold core 1 together into a hot air vulcanization tank for vulcanization. No need to inject pressure into the vulcanization tank, that is, vulcanize under normal pressure conditions;

[0021] IV, vulcanization is complet...

Abstract

A hot-air vulcanization process for multi-layer winding rubber straight tubes with polyester film as the coating layer. Polyester film is used as the coating layer of rubber tube vulcanization. During vulcanization, the product quality can be guaranteed without applying vulcanization pressure, reducing It reduces vulcanization energy consumption, saves cost, and can make the vulcanized hose surface smooth and beautiful without impurities. Moreover, this kind of polyester film can be recycled and reused. In the environment where existing resources are becoming more and more scarce, it plays the role of environmental protection and resource saving; It is very good to ensure the safety of production. The rubber hose produced by the invention can be used for the flexible connection of diesel engine pipelines or the flexible connection of water and gas pipelines of equipment such as automobiles and engineering machinery.

Description

technical field [0001] The invention relates to a multi-layer winding hot air vulcanization process of rubber straight pipes, in particular to a multi-layer winding rubber straight pipe hot air vulcanization process with polyester film as the coating layer. Background technique [0002] The traditional multi-layer winding rubber straight pipe is vulcanized by hand-wrapping and then wrapped with water-wrapped cloth. For example, the patentee Liu Jianping’s patents CN2878852Y and CN1302912C disclose rubber pipes made by this production process. The above two patent documents have passed References are incorporated here. This process has the following disadvantages: (1) the water-wrapped cloth will easily cause the air bubbles in the tube blank to escape easily, resulting in defects such as delamination of the inner rubber layer; (2) the rubber tube covered by the water-wrapped cloth is easily separated from The outer layer of rubber is bonded together and it is difficult to r...
