Problems solved by technology

Existing insulating materials for telecommunication cables have poor mechanical properties and are prone to aging. Within a certain period of use, they are prone to aging, cracking, or even falling off due to external light.
The insulating coating on the surface of the telecommunication cable cracks or falls off, which will cause leakage and short circuit, posing a threat to human life.

Abstract

The invention discloses a surface insulating coating for communication cables, and relates to the technical field of insulating materials. The surface insulating coating comprises the following raw materials of: in parts by weight, 30-40 parts of an acrylonitrile-butadiene-styrene copolymer, 10-18 parts of epoxy resin, 10-15 parts of silicone grease, 5-12 parts of polyvinyl acetal, 6-13 parts of silane, 4-9 parts of phosphoric acid or phosphate, 1-4 parts of a surfactant, 1.5-3 parts of a curing agent, 1.6-2.8 parts of a film forming agent, 0.4-0.8 part of an initiator and 1-2 parts of an assistant. The surface insulating coating for the communication cables has stable chemical properties, strong mechanical resistance, difficult aging and strong cohesive force, and does not fall off easily, and the preparation method is simple and easy to operate, and has a good prospect of market application.

Description

technical field [0001] The invention relates to the technical field of insulating materials, in particular to a surface insulating varnish for telecommunication cables and a preparation method thereof. Background technique [0002] Insulating varnish, also known as insulating coatings, is a coating with excellent electrical insulation. It has good electrochemical properties, thermal properties, mechanical properties and chemical properties. It is mostly varnish and colored paint. Insulating varnish is a kind of special varnish in varnish. Insulating varnish is an important insulating material based on high molecular polymer, which can be cured into an insulating film or an insulating whole under certain conditions. [0003] Telecommunication cables are wire products used to transmit electric energy, information and realize electromagnetic energy conversion. In order to isolate conductor current and protect personal and equipment safety, the outside is usually covered with ...
