Abstract

The present invention discloses an inorganic high-temperature resistant and antistatic coating. The coating is mainly prepared from constituents of the following contents (percentages by weight): 30 to 60% of phosphate, 5 to 25% of silicasol, 2 to 10% of boric acid, 25 to 45% of water, 2 to 5% of titanate coupling agent, 8 to 18% of conductive mica powder and 5 to 10% of aluminium powder mixed with zinc oxide. Dihydric phosphate water solution is prepared from the following substances at least, and the phosphate consists of one or several of aluminium dihydrogen phosphate, aluminium hydrogen phosphate, magnesium dihydrogen phosphate, magnesium hydrogen phosphate, zinc dihydrogen phosphate and zinc hydrogen phosphate. The ratio of P to M (M refers to metal elements) in the phosphate is from 1.2 to 2.6. The conductive mica powder and the aluminium powder mixed with zinc oxide are processed by the titanate coupling agent before being added to a base material.

Description

technical field [0001] The invention relates to an inorganic high temperature resistant and antistatic coating. It mainly provides certain antistatic properties for materials used in high temperature environments. Background technique [0002] A high-speed aircraft flies in the air at high speed and friction with the air generates a lot of heat, and at the same time, a large amount of static electricity is generated on the surface of the material. If it is not eliminated in time, the discharge will cause great harm. Traditional organic coatings deteriorate at high temperatures, reduce their strength, and peel off, which cannot effectively protect high-speed aircraft. The present invention is to develop an inorganic high-temperature-resistant antistatic coating to solve this problem. Contents of the invention [0003] The purpose of the present invention is to provide a new type of inorganic high temperature resistant antistatic coating for the antistatic properties of ma...
