The invention discloses a quick-drying far infrared constant temperature gold copying brick and a preparing method thereof. On one hand, the gold copying brick and a carbon fiber infrared heating material are combined, the problem that it takes a large amount of time to naturally dry when a traditional gold copying brick naturally absorbs volatilization moisture is solved, a user can control the temperature of the gold copying brick more accurately and can control the speed of disappearing of handwriting according to the demands, the thickness of the whole gold brick is appropriate, the weight of the whole gold copying brick is greatly reduced through a plastic outer frame, and the gold copying brick is convenient to carry and move. The carbon fiber heating body has the advantages of being high in temperature rising speed, small in thermal lag, even in heating, long in thermal radiation transmitting distance, high in heat exchanging speed, long in service life and the like, and the electric heating converting efficiency reaches up to 98 percent. The carbon fiber heating body can effectively activate the human tissue cells, promote blood circulation, accelerate metabolism and enhance immunocompetence, has the effects such as deodorization, dehumidification and antibiosis and is light and friendly to the environment, energy is saved, and the safety performance of the quick-drying far infrared constant temperature gold copying brick is guaranteed.
