Abstract

The invention discloses a preparation method of a silica gel steel wire corrugated pipe. The preparation method comprises the following steps of: 1) mixing silicone rubber so as to obtain mixed silicone rubber, and further preparing part of the mixed silicone rubber into silica gel pieces; 2) calendaring the residual mixed silicon rubber in the step 1) on a piece of screen cloth so as to prepare silica gel cloth-reinforced rubber; 3) winding the silica gel pieces, the silica gel cloth-reinforced rubber, steel wires, the silica gel cloth-reinforced rubber and a piece of cellophane from inside to outside in sequence outside a corrugated pipe; 4) carrying out secondary vulcanization treatment on the corrugated pipe wound in the step 3), and cutting the pipe head so as to obtain the silica gel steel wire corrugated pipe. The preparation method employs secondary vulcanization and strict vulcanization process condition control, and the prepared silica gel steel wire corrugated pipe has good flexibility and deflection capability; meanwhile, as vulcanized silicon rubber takes the place of ordinary rubber to be wound outside a corrugated pipe mold, the prepared silica gel steel wire corrugated pipe is high in temperature resistance, long in service life and attractive in appearance.

Description

technical field [0001] The invention relates to a steel wire bellows, in particular to a method for preparing a silicone steel wire bellows. Background technique [0002] Steel wire corrugated pipes are mainly used on pipelines laid in water conservancy and electric power systems, such as heat pipe interfaces and return water pipeline interfaces of power plants, to compensate for displacement and misalignment of pipelines within a certain range. The existing steel wire corrugated pipe is generally prepared by spirally winding the inner layer rubber, steel wire and outer layer rubber outside the bellows mold, and then undergoes vulcanization treatment. Because the existing steel wire bellows is wound with ordinary rubber, the steel wire bellows produced are not resistant to high temperature and have a short service life; and the appearance is all black, which affects the appearance. Contents of the invention [0003] The purpose of the present invention is to provide a met...
