Abstract
The invention discloses a preparation method of high temperature-resistant, radiation-insulated, heat-conducting and microwave-permeable inorganic coating, which comprises the following steps: preparing sol with ethyl orthosilicate, alcohol, deionized water and hydrochloric acid; synthesizing monox microballoon with the diameter of 0.3-3 micrometers with ethyl orthosilicate, isopropanol, deionized water and ammonia water; growing a titanium oxide shell layer which has the depth from 30-500nm and has high refractivity on the monox microballoon to obtain a stuffing of a nuclear shell structure. The prepared grain with nuclear shell structure is used as the stuffing to be dispersed into the sol so as to be capable of obtaining the compact and even inorganic coating after heat treatment. The added dye with the nuclear shell structure is high in reflectivity to the infrared thermal radiation from 1-10 micrometers, the adding quantity of the stuffing is very small, and the increase of the dielectric constant of the coating is less, so that the preparation method leads the coating to be higher in the thermal reflectivity and not be capable of influencing the microwave permeability, thereby being applied to high-temperature protection at the temperature of 1200 DEG C.
