This application relates to the field of colorants, and in particular to a high thermal conductivity organosilicon colorant and its preparation method. In this application, titanium dioxide is attached to the surface of long thermally conductive particles such as whiskers using a titanium source to form a titanium dioxide-long thermally conductive particle composite system, which is then dispersed in a polymer carrier. The attached titanium dioxide enhances the coloring performance of the long thermally conductive particles. Compared with directly mixing titanium dioxide and whiskers, this method provides better coloring and thermal conductivity at the same mass.
