Abstract

The invention discloses a high-temperature-resistant antistatic coating. The antistatic coating uses a two-component modified silicone resin as a matrix, and metal oxide semiconductor powder as a conductive filler, and the mass ratio of the two is (9-14): 6; the antistatic coating of the present invention has excellent antistatic performance and high temperature resistance performance, can replace the antistatic coating on the surface of most radomes at present, and can meet the antistatic performance under the high temperature condition of 250°C Requirements: The present invention also discloses a preparation method of the antistatic coating correspondingly, including ball milling, spraying, curing and heat treatment. The whole preparation process is simple and highly controllable, and can be effectively applied to industrial production.

Description

technical field [0001] The invention mainly relates to a coating material composition and a preparation method thereof, in particular to an antistatic coating containing resin and metal oxide and a preparation method thereof. Background technique [0002] Antistatic coating is an integral part of the use of various radome, it is usually on the outermost layer of the radome, the performance of the radome requires that the antistatic coating should have good wave permeability and environmental resistance , At the same time, in order to meet the use of the radome under certain high temperature (such as 200 ℃) conditions, the antistatic coating also needs to have high temperature resistance. [0003] At present, a series of antistatic coatings have been developed at home and abroad in response to various requirements for the use of radome, but there are some common problems, such as poor adhesion on the surface of quartz ceramic radome, conductive carbon black (or metal) Powder...
