Abstract

The invention provides a filler which can radiate infrared and an application method in coating, relating to coating additive technical field. The preparation method of the filler is divided into the steps: 1. preparing metal oxide mother liquid doped with rare earth; 2. preparing gel; 3. preparing tourmaline metal oxide powder doped with rare earth; 4. preparing tourmaline metal oxide powder doped with secondary baked rare earth; 5. preparing filler product which can radiate infrared. The infrared radiation filler which is synthesized and mixed with the normal coating, can generate the infrared radiation coating, with the intensified radiation function. After renovation the filler can effectively radiate infrared in low temperature ranging from 50-200 DEG C and thermal conductive capacity thereof is evidently increased and the temperature of thermal pipe surface is increased when the thermal pipe surface is coated with the coating.

Description

technical field [0001] The technical solution of the invention relates to the technical field of paint additives, in particular to an infrared radiation filler and its application method in paint. Background technique [0002] For the heating device, the heat dissipation effect of the radiator directly affects the scale of the radiator device and the temperature of the heat transfer medium used. By strengthening the heat radiation efficiency of the surface of the radiator device, the heat energy accumulated in the heat transfer medium can be quickly dissipated to the environment, so that the efficiency of the heat dissipation equipment can be improved, and energy saving and environmental protection can be realized. Infrared radiation coating has strong penetrating power and fast radiation heat transfer. It can be used on the surface of radiator device to strengthen the heat radiation efficiency of radiator device surface, thereby improving the efficiency of heat dissipation ...
