Embodiment 1

[0021] A high-temperature resistant antistatic coating of the present invention. The antistatic coating uses two-component modified silicone resin as a matrix, ATO semiconductor powder as conductive filler, two-component modified silicone resin and ATO semiconductor The mass ratio of the powder is 3:2; in this example, the two-component modified silicone resin is composed of TR613 heat-resistant topcoat with a solid content of 75% and a mass ratio of 5:1 (Jiangyin Osaka Paint Co., Ltd.) and curing agent (the curing agent corresponding to TR613 heat-resistant topcoat produced by Jiangyin Osaka Paint Co., Ltd.).

[0022] The preparation method of the above-mentioned antistatic coating includes the following process steps:

[0023] (1) Ball milling: weigh 3:2 two-component modified silicone resin (the solid content is 75% and the mass ratio is 5:1 TR613 heat-resistant topcoat and the corresponding curing agent) and ATO semiconductor powder Mix the two to form a slurry, and then use a...

Embodiment 2

[0029] A high temperature resistant antistatic coating of the present invention. The antistatic coating uses a two-component modified silicone resin as a matrix, an ITO semiconductor powder as a conductive filler, a two-component modified silicone resin and an ITO semiconductor The mass ratio of the powder is 7:3; in this example, the two-component modified silicone resin is composed of TR613 heat-resistant topcoat with a solid content of 75% and a mass ratio of 5:1 (Jiangyin Osaka Paint Co., Ltd.) and R30 curing agent.

[0030] The preparation method of the above-mentioned antistatic coating is: first weigh the two-component modified silicone resin with a mass ratio of 7:3 (the solid content is 75% and the mass ratio is 5:1 TR613 heat-resistant topcoat And R30 curing agent) and ITO semiconductor powder, and then ball milling, spraying, curing and heat treatment according to the same preparation process steps and process parameters as in Example 1 to obtain the high temperature r...

Abstract

The invention discloses a high temperature resistant antistatic coating, which is prepared from bi-component modified organic silicon resin serving as a matrix and metal oxide semiconductor powder serving as a conductive filler in a mass ratio of (9-14):6. The antistatic coating has excellent antistatic property and high temperature resistance, can replace most conventional antistatic coatings onradomes, and can meet the antistatic requirement under the 250DEG C high temperature condition. The invention correspondingly discloses a method for preparing the antistatic coating, which comprises process steps of ball milling, spraying, curing, thermal treatment and the like; and the whole preparation process has simple steps and high controllability 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...
