Abstract

The invention relates to a silicon resin composition for nuclear motor mica tape. The silicon resin is mainly prepared by the following raw materials which comprise, by mass percent, 10-50% of methyl MQ silicon resin, 9-25% of phenyl MQ silicon resin, 5-30% of hydroxyl silicone rubber, 10-40% of phenyl silicone rubber, 40% of organic solvents and 0.005-0.02% of basic catalysts. The nuclear motor mica tape using the silicon resin composition is low in product production cost, high in surface abrasive resistance, good in flame retardant performance, self-extinguishing resistance and insulating performance and resistant to high temperature and radiation, and has sufficient strength and proper ductility.

Description

technical field

[0001] The present invention relates to a silicone resin composition for nuclear power mica belts and applications thereof, in particular to a silicone resin composition for nuclear power mica belts and a binder prepared from the silicone resin composition. A nuclear power mica tape and a preparation method of the mica tape. Background technique

[0002] Mica tape, also known as refractory mica tape, is a fire-resistant insulating material, which can be divided into: mica tape for motors and mica tape for cables. According to the structure, it is divided into: double-sided belt, single-sided belt, three-in-one belt, double-film belt, single-film belt, etc. According to mica, it can be divided into: synthetic mica tape, phlogopite mica tape, and muscovite tape.

[0003] Mica tape is a composite insulating material, mainly composed of three materials: dielectric material, reinforcing material, adhesive.

[0004] At present, the motor is developing towards hi...
