Embodiment 1

[0031] A paint construction process for a radome, comprising the steps of:

[0032] (1) Washing and drying

[0033] First, the surface of the radome is washed with water for 20 minutes, and then dried in an oven, the temperature of the drying is 50°C, and the drying time is 30 minutes;

Abstract

The invention discloses a coating application technology of radomes. Acetic ether and PMA of diluting agents can dissolve coatings well, the drying speed of paint films is appropriate, the price is relatively low, the coatings comprise nanometer conductive powder so as to realize the antistatic function, the number of times of spraying the coatings is 1-3, the thickness of the coatings is 25-35 micrometers, the interval time of coating spraying is determined, the mass can be reduced, the permeability to radar waves is high, the curing time is determined, and the surface resistance of the coatings can be lowered. The radomes processed through the coating application technology have the advantages that the antistatic ability is high, the surface resistance is low, the market potential is huge and the prospect is wide.

Description

technical field [0001] The invention belongs to the field of radar production technology, and more specifically, the invention relates to a coating construction technology of a radome. Background technique [0002] With the development of modern high technology, radars are widely used in aircraft, missiles, navigation and other fields, and the use of radomes is also becoming more and more extensive. The radome is the window of electromagnetic waves. Its function is to protect the antenna and prevent the environment from affecting and interfering with the working state of the radar antenna, so as to reduce the power driving the antenna, improve its working reliability, and ensure the radar antenna to work around the clock. The existence of the radome prolongs the service life of the antenna, simplifies the structure of the antenna, and reduces the weight of the structure. The radome is an important part of the radar system, and its performance directly affects the function o...
