Abstract

The invention discloses a processing method for insulation and flame resistance of buses. The method comprises the following steps of: processing and pre-heating the surface of a bus; and carrying out fluidized bed coating and high-energy ultrasonic assistance, and carrying out cleaning and curing. According to the processing method for insulation and flame resistance of buses, the high temperature resisting and high voltage resisting characteristics of the buses are increased, and the high thermal conduction, waterproofness, bubble-free property and small film coating thickness of the buses are ensured at the same time, wherein the temperature resistance of the buses achieves an H level (180 DEG C) which is 50 DEG C higher than a B level (130 DEG C).

Description

technical field [0001] The invention belongs to the technical field of busbar insulation and flame-retardant treatment, and in particular relates to a busbar insulation and flame-retardant treatment method. Background technique [0002] The flame retardants currently developed can be divided into inorganic flame retardants (such as antimony trioxide, magnesium hydroxide, magnesium hydroxide, etc.) and organic flame retardants (such as brominated flame retardants, chlorine-based flame retardants, etc.) Flame retardants, etc.) two categories. Compared with organic flame retardants, inorganic flame retardants are more stable, less volatile, less toxic to smoke, and lower in cost, so they have been vigorously developed and widely used. [0003] Bus bar refers to products made of high-conductivity copper or aluminum bars, magnesium materials, used to transmit electric energy, and capable of collecting and distributing electric power. The main conductor used to transmit electric...
