Abstract

The invention relates to an adhesive for producing a laminated bus insulating pad, a preparation method of the adhesive and a production method of the insulating pad. Substances for constituting the adhesive comprise liquid epoxy resin, solid epoxy resin, a latent curing agent, butadiene-acrylonitrile rubber, highly heat-conducting modified inorganic powder and an organic solvent. The preparation method of the adhesive comprises the following steps of: proportioning; mixing; and the like. The production method of the insulating pad comprises the following steps of: selecting an insulating base layer; coating the adhesive; and drying the formed adhesive layer. The adhesive has the advantages of high heat conductivity, high adhesion strength, high toughness and the like; the insulating pad has the characteristics of low raw material cost, simple and convenient manufacturing process, high heat conductivity, high shear strength and high electric performance conservation rate of the insulating pad before and after bending; and a laminated bus which is prepared by using the insulating pad has the characteristics of high heat conductivity, quick radiation, high workability, high electric performance conservation rate and the like and can meet the bus bending requirement.

Description

technical field [0001] The invention relates to an adhesive used for producing laminated busbar insulating liners, a preparation method thereof and a production method of the insulating liners. Background technique [0002] Laminated busbars of high-power converters have broad development prospects due to their excellent performance characteristics such as low inductance and easy installation. The high-power laminated busbar is stacked together in the form of thin and wide copper bars, and the layers are hot-pressed into one with a thin and high-insulation-strength material. This overall high-power laminated busbar structure can be It can withstand hundreds of kilograms of shear stress, and the voltage between its conductive electrodes can withstand thousands of volts. In order to meet the performance requirements of high-power laminated busbars, its high dielectric strength materials play a vital role. At present, in domestic reports on busbar manufacturing, some producti...
