Problems solved by technology

The most important reason for power shortage is that the increase in installed capacity cannot keep up with the growth rate of electricity consumption. Therefore, it is necessary to increase the scale and manufacturing speed of power projects and improve the capacity of power production. This requires the rapid development of large-scale high-voltage motor manufacturing. However, the process cycle of manufacturing the main insulation of the motor is long, which affects the development speed. The existing adhesive resin composition has too long curing time during the molding and curing process of manufacturing the main insulation, which seriously affects the effect of manufacturing the main insulation.

Abstract

The invention discloses an adhesive resin composite for preparing F-level multi-gelatine powder mica and a preparation method thereof. The preparation method comprises the following steps of: mixing a mixed solution of tung oil and maleic anhydride and a mixed solution of methylbenzene and BMI (Bismaleimide); then adding a mixed solution of bisphenol A epoxide resin, heat-proof epoxide resin and an accelerating agent to the mixed solution. The preparation method disclosed by the invention has the advantages of simple reaction process, simple method and easiness for operation. According to the prepared adhesive resin composite, the mould pressing curing process of manufacturing a main insulator is in a short time, so that the curing time is greatly shortened, and the effect on manufacturing the main insulator is enhanced; the mechanical and electric property is superior due to complete curing.

Description

technical field [0001] The invention belongs to the field of insulating materials, and in particular relates to an adhesive resin composition used for preparing F-class multi-glue powder mica and a preparation method thereof. Background technique [0002] As we all know, the level of a country's large-scale high-voltage motors directly affects the development of the country's electric power industry and the development of the national economy. The main insulation part of the motor coil is the heart of the motor, and its level determines the level of the motor. Guaranteed at all. The main insulation of the wire rod is made by wrapping with F-class multi-glue powder mica tape and then molded and solidified. Among them, the structure of the mica tape product is double-sided electrician alkali-free glass cloth for reinforcement, and the middle is a special high-pressure-resistant inorganic material powder mica paper, and the two are bonded into a whole through a special organic...
