Title:
THERMALLY CONDUCTIVE INSULATING PAINT AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/103849
Kind Code:
A1
Abstract:
Disclosed are a thermally conductive insulating paint and a preparation method therefor. The thermally conductive insulating paint comprises the following raw materials: polyol, acid anhydride, modified carbon nanotubes, a crosslinking monomer and an initiator. The modified carbon nanotubes are prepared by means of the following method: 1) preparing surface carboxylated carbon nanotubes; and 2) dissolving the surface carboxylated carbon nanotubes in a mixed solution of water and ethanol, and adding ethyl orthosilicate, vinyl triethoxy silane and ammonia water for a reaction to obtain the modified carbon nanotubes, the modified carbon nanotubes having a vinyl group on the surface thereof. The preparation method is as follows: the polyol and the acid anhydride are mixed and then react in stages at different temperatures in the presence of a protective gas, and then the remaining raw materials are added, mixed and react to prepare, wherein the modified carbon nanotubes may be added together with the acid anhydride or comprised in the remaining raw materials. The present invention has high thermal conductivity and insulation properties while also having excellent mechanical properties.
