Problems solved by technology

If the bus bar is directly electrostatically sprayed with 10-5017 blue epoxy powder, the current international and domestic basic coating thickness is in the range of 50 μm to 90 μm, the coating thickness does not meet the requirements, and the coating’s withstand voltage value is at a frequency of 50HZ. When the maximum leakage current is 0.83mA, the maximum withstand voltage does not exceed 900V. During use, the coating is easily broken down, and various bus bars are short-circuited, etc., which will affect the power supply system.

Embodiment Construction

[0019] Describe the present invention below in conjunction with specific embodiment:

[0020] In this example, the bus bar is electrostatically sprayed with 10-5017 blue epoxy powder, and the coating thickness of the bus bar is required to be in the range of 101 μm to 254 μm, and the withstand voltage value is at a frequency of 50HZ and a voltage of 1250V. More than 0.83mA. However, the international and domestic basic coating thickness is in the range of 50μm to 90μm, and the withstand voltage value of the coating is at a frequency of 50HZ and a maximum leakage current of 0.83mA, and the maximum withstand voltage does not exceed 900V. Hot parts can effectively increase the coating thickness of electrostatic spraying, and by controlling the preheating temperature of the parts and various parameters of electrostatic spraying, the coating thickness of the bus bar after 10-5017 epoxy powder electrostatic spraying can be controlled at In the range of 101μm to 254μm, while the wit...

Abstract

The present invention proposes a process for electrostatically spraying 10-5017 blue epoxy powder on copper parts. By preheating the parts for 5 minutes to 10 minutes at a temperature of 100°C to 104°C, the coating thickness of electrostatic spraying can be effectively increased, and By controlling the preheating temperature of the parts and various parameters of electrostatic spraying, the coating thickness of the bus bar can be controlled within the range of 101 μm to 254 μm after electrostatic spraying of 10-5017 epoxy powder, and the withstand voltage value is at frequency 50HZ, voltage At 1250V, the maximum leakage current within 30S does not exceed 0.83mA, which meets the designer's coating requirements for bus bar 10-5017 blue epoxy powder electrostatic spraying.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a process method for electrostatically spraying 10-5017 blue epoxy powder on copper parts. Background technique [0002] With the launch of the domestic large aircraft project, as a supplier of the large aircraft power system, in the process of cooperating with the design unit, referring to the design standards of the other party, the bus bar of the power supply system is required to use AkzoNober10-5017 blue epoxy powder coating, Because the coating has good protective and insulating properties, it can be used as an insulating and protective coating for bus bars used in aircraft high-power power generation and distribution systems. [0003] The power distribution system of large passenger aircraft is transmitted through various bus bars. Due to the weight reduction of the aircraft and the reduction of the occupied volume of each part, the power supply is connected in p...
