Abstract

The invention discloses an epoxy adhesive for a motor of an electric vehicle and a preparation method of the epoxy adhesive. The epoxy adhesive is formed by solidifying a component A and a component B in equal mass, wherein the component A contains the following components in parts by mass: 20 parts of E-51 epoxy resin, 5 parts of special epoxy resin, 10 parts of hydantoin resin, 2 parts of an epoxy diluent, 25 parts of 20micron spherical silicon powder and 26.8 parts of 27micron spherical silicon powder; the component B contains the following components in parts by mass: 25 parts of methylhexahydrophthalic anhydride, 10 parts of chlorendic anhydride, 30 parts of 20micron spherical silicon powder, 28.8 parts of 27micron spherical silicon powder and 1 part of 2-hexyl-4-methylimidazole. The epoxy adhesive is used for insulating, waterproof and leakage-resistant protective packaging of the motor of the electric vehicle, and has excellent properties of high thermal conductivity, a low linear expansion coefficient and high temperature resistance.

Description

technical field [0001] The invention belongs to the field of epoxy potting adhesive materials, and relates to an epoxy adhesive for electric vehicle motors and a preparation method thereof. Background technique [0002] With the deepening of the global energy crisis, the depletion of oil resources and the increasing harm of air pollution and global temperature rise, governments and automobile companies in various countries generally recognize that energy saving and emission reduction are the main direction of future automobile technology development. The development of electric vehicles will It is the best way to solve these two technical difficulties. The biggest advantage of electric vehicles is to lead the development direction of the future automobile industry, which is low-carbon, informatization, and intelligent. Electric vehicles have better energy and environmental benefits than conventional vehicles throughout their life cycle. [0003] As the main component of ne...
