Description

Technical Field

[0001] This utility model relates to the field of insulating materials, and in particular to a water-soluble resin-coated insulating paper. Background Technology

[0002] In electrical equipment, insulating paper is an important insulating component, and its performance directly affects the safe and stable operation of the equipment. Traditional insulating paper has certain limitations in terms of moisture resistance and insulation performance. For example, ordinary cellulose insulating paper easily absorbs moisture from the air, which leads to a decrease in mechanical properties and insulation performance, and it is also flammable, posing a safety hazard.

[0003] Some existing resin-coated insulating papers use alcohol-soluble resins, which require a large amount of organic solvents during production. This not only results in high costs and difficult recycling, but also pollutes the environment and is not suitable for current use. Therefore, we propose a water-soluble resin-coated insulating paper to solve the above problems. Utility Model Content

[0012] In a further embodiment, the waterborne boron phenolic resin has high temperature resistance and mechanical properties.

[0013] Compared with the prior art, the beneficial effects of this utility model are:
