Problems solved by technology

[0004] Variable frequency speed regulating motors are widely used in all aspects of production and life due to their superior performance, but in the process of use, there will be necrosis caused by the high temperature of the motor due to its own operation. Therefore, in order to improve the reliability and To further improve the winding insulation and main insulation of variable frequency motors, it is necessary to seek an insulating material with better mechanical properties and high temperature resistance to solve this problem

Abstract

The invention relates to a modified montmorillonite coated polyester fiber composite material. Polyester fiber is adopted as the basis material, montmorillonite is treated with an Na2CO3 solution to obtain sodium based montmorillonite, tetramethyl ammonium bromide is taken as an intercalation agent to conduct organic modification on sodium based montmorillonite, the modified montmorillonite is employed to coat the basis material surface by Layer-by-Layer (LbL) self-assembly process so as to form a compact protective layer on the surface, thus improving the high temperature resistance and mechanical properties of the polyester fiber material. The material is used for winding insulation of a variable frequency motor and a main insulating material, can effectively improve the heat resistance temperature and mechanical strength of the motor, improve the reliability of the variable frequency motor, and prolong its service life.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a modified montmorillonite-coated polyester fiber composite material and a preparation method thereof. Background technique [0002] Polyester fiber, commonly known as polyester, is a fiber-forming high polymer produced from dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions--polyphenylene Ethylene glycol diformate (PET), a fiber made by spinning and post-processing. Polyester fiber has the advantages of high strength, good elasticity, good thermoplasticity, good wear resistance and corrosion resistance. [0003] Using polyester fiber alone as an insulating material has poor performance. Using modified montmorillonite as an inorganic component and polyester fiber as a matrix material to prepare a composite material can improve the mechanical strength and high temperature resistance of polyester fiber...
