Problems solved by technology

Nano-silica has a large specific surface area and high specific surface energy. It is easy to agglomerate in the coating to form secondary particles, resulting in a decrease in the performance of strengthening and toughening. At the same time, the hydroxyl groups on the surface also strengthen this phenomenon.

Description

technical field [0001] The invention relates to the technical field of heat-dissipating coatings, in particular to an impact-resistant and heat-dissipating coating and a preparation method thereof. Background technique [0002] With the rapid development of modern science and technology, the high frequency and high speed of electronic devices and the density and miniaturization of integrated circuits have greatly increased the total power density and calorific value of electronic devices per unit volume, thus making the cooling of electronic devices more difficult. increasingly prominent. However, the cooling capacity achieved by conventional cooling systems is greatly challenged, especially in the fields of energy, automobiles, air conditioning, agriculture, chemicals, heating, aerospace, microelectronics, information, etc. put forward higher requirements. The heat dissipation paint is a special paint that improves the heat dissipation efficiency of the surface of the obj...
