The invention relates to a preparation method for a high-temperature-resistant radiation coating, and belongs to the technical field of preparation of coatings. The method comprises the following steps: obtaining modified organic silicon resin which has high temperature resistance and is provided as a binder by virtue of boric acid, performing surface modification under the action of microorganisms by virtue of carboxyl-rich dark plum fruits to improve the dispersibility and avoid the phenomenon of clustering, regulating the caking property by virtue of mica powder, and performing compounding to obtain the high-temperature-resistant radiation coating. The prepared radiation coating is high in radiation performance, temperature resistance and aging resistance, and has a broad application prospect. 本发明涉及种耐高温散热涂料的制备方法，属于涂料制备技术领域。该方法首先用硼酸改性有机硅树脂提供其耐高温性能并将其作为基料，再用富含羧基的乌梅在微生物的作用下进行表面改性，提高其分散性能，避免团簇现象的发生，最后用云母粉调节粘结性，复配后即得耐高温散热涂料的方法，本发明制备的散热涂料散热性能好，耐高温性和耐老化性能优异，具有广阔的应用前景。
