However, among these resins, epoxy resins and unsaturated polyester resins cannot be cast or molded if they are hard.
After curing, the resin itself has dust that can cause cracks, and if it is soft, its cracking properties change greatly depending on the ambient temperature.On the other hand, silicone resins have weak mechanical strength and are expensive. It had some drawbacks. The present invention relates to a liquid resin composition for electrical insulation that has been created in view of the above-mentioned matters, and in particular has hydrogenated resin compositions that are highly flexible and exhibit little thermal aging change (no change in dielectric properties) in terms of properties. Focusing on the 1,2-polyptadiene resin, Nippon Soda Co., Ltd.'s "GITIOOO
By combining the company's acrylic modified 1,2-polybutadiene resin ``TE2000'' and a copolymerizable vinyl monomer, it maintains the flexibility of the resin while improving surface drying and mechanical properties. The present invention relates to a liquid resin composition for electrical insulation which has excellent properties of strength, and which has a long reaction time and can obtain a final cured product in a short period of time.

I wrote qo or more. ) As is clear from the above-mentioned Examples and Comparative Examples, the liquid resin composition for electrical insulation of the present invention comprises a hydrogenated 1,2-polybutadiene-terminated acrylic modified resin and an acrylic-terminated 1,2-polybutadiene resin. , and a copolymerizable vinyl monomer as the main components, it maintains the flexibility of the resin, has excellent mechanical strength, electrical properties, and surface drying properties, and is quick to react. The final cured product can be obtained in a short period of time, making it effective for impregnating and casting electrical parts.In particular, by adding flame retardancy, it can be used, for example, to handle high voltages such as cathode ray tube anodes in television receivers. If used as impregnation/casting for a flyback transformer for applying voltage, it will produce great effects.
