Description

technical field [0001] The present application relates to the technical field of construction, in particular, to a heat-conducting adhesive and a synthesis method thereof. Background technique [0002] Solar energy is an inexhaustible and inexhaustible source of energy. In order to convert solar energy into usable energy without pollution, photovoltaic curtain wall technology came into being. The photovoltaic curtain wall converts light energy into electrical energy through photovoltaic modules. When the photovoltaic curtain wall absorbs solar energy and converts it into electrical energy, most of the solar energy is converted into heat energy, which makes the temperature of the photovoltaic curtain wall rise. The rise of curtain wall temperature will reduce the conversion efficiency of photovoltaic modules on the one hand, and on the other hand, it will also cause high-temperature fire hazards. [0003] The metal structural support of the curtain wall itself has a large ...
