HEAT-CONDUCTING ADHESIVES BASED ON POLYURETHANES MODIFIED WITH METAL PARTICLES AND CARBON NANOTUBES Shchegolkov A.V. , Ph.D. (Engineering), Associate Professor, e-mail: energynano@yandex.ru Hrobak A.V . Ph.D. student, Post-graduate Student, e-mail: nastiarx@yandex.ru Tambov State Technical University, 106 Sovietskaya st., Tambov, Russian Federation Abstract New technologies for connecting various parts are an important part of the development of modern mechanical engineering. In some cases, the most effective is the adhesive joint. It does not require mechanical processing of parts and provides connections that can be re-installed. In addition to high mechanical strength, the adhesive joints must meet the requirements of high thermal and electrical conductivity. To obtain an effective adhesive composite, carbon nanotubes can be used, which together with a dispersed metal filler, can increase strength and improve thermal conductivity. Mechanical activation can be used to increase the efficiency of carbon nanotubes. Effective mechanical activation can be achieved in the case of high-energy impact, which is implemented in the devices of the vortex layer. Keywords adhesive composite, thermal conductivity, mechanical activation, carbon nanotubes.
