Abstract

The invention provides a preparation method and application of efficient heat-conducting UV-LED printing ink. Firstly, a melamine-formaldehyde prepolymer is synthesized, then aluminum carbide is stripped through a lithium fluoride acid solution to prepare Mxene, finally, the melamine-formaldehyde prepolymer and the stripped Mxene are subjected to in-situ polymerization, melamine-formaldehyde modified Mxene is obtained, and the efficient heat-conducting UV-LED printing ink is obtained. Mxene is subjected to embedding treatment by adopting melamine-formaldehyde resin, so that the dispersity of Mxene is improved, the technical problem of poor compatibility of Mxene and an ink matrix is solved, and the efficient heat-conducting UV-LED ink is prepared by adopting the binder, the pigment and various auxiliaries as auxiliary materials, so that the efficient heat-conducting UV-LED ink is prepared. The UV-LED heat-conducting ink is prepared by adding the Mxene into the UV-LED heat-conducting ink, so that the agglomeration of the Mxene is effectively prevented, the heat conductivity of the heat-conducting ink is greatly improved, and the heat conductivity coefficient of an ink film in the plane direction after printing is up to 1.32 W / m.K.

Description

technical field [0001] The invention belongs to the technical field of polymer ink, and in particular relates to a high-efficiency heat-conducting UV-LED ink and a preparation method thereof. Background technique [0002] With the increasing maturity of 5G technology, electronic devices are gradually developing in the direction of miniaturization, high integration and intelligence, and the resulting heat accumulation problem has become a key factor affecting the life of electronic devices. A large number of studies have shown that within the appropriate operating temperature range, for every 1°C drop in the operating temperature of electronic devices, the failure rate decreases by 4%; when the temperature is 20°C higher than the maximum set temperature, the failure rate is as high as 100% %. Therefore, the research and development of high-performance heat dissipation materials has become an important topic in the field of electronic device applications. [0003] Many schol...
