Abstract

The invention provides a preparation method of an adhesive assorted with a liquid crystal coated optical cable. In the preparation method of the adhesive assorted with the liquid crystal coated optical cable, alpha, omega-terminal hydroxyl polymethyl vinylphenyl silicone rubber or alpha, omega-terminal hydroxyl polydimethyl diethyl siloxane with good low temperature performance is taken as a main material, nano-filler-reinforced silicone rubber adhesive is used for improving mechanical properties thereof, and according to a vulcanization mechanism of a dealcoholized room temperature vulcanization silicone rubber, room temperature vulcanization silicone rubber adhesive with excellent low temperature performance and moderate releasing force is prepared. When the adhesive is used for winding an optical cable coil, releasing forces at normal temperature and low temperature are moderate and wires can be smoothly unwound, thus meeting requirements of practical application and particularly meeting a requirement on the releasing force in a low temperature environment.

Description

technical field [0001] The invention relates to a preparation method of an adhesive for a liquid crystal coated optical cable, in particular to a method for preparing an adhesive for a liquid crystal coated optical cable which is applicable to a low temperature environment. Background technique [0002] The optical cable coating material has developed from aramid fiber braided mesh coating to the current liquid crystal polymer coating layer, which solves the problem of thermal expansion mismatch between the optical cable coating layer and the quartz optical fiber, and the production of aramid fiber coating using light-curing coating. Many problems such as slow speed also put forward new requirements for its matching adhesive. At present, there are mainly the following problems in the adhesive for optical cables: (1) Under low temperature conditions, the release force of the adhesive increases rapidly due to crystallization, and too much release force will lead to uneven or...
