A composite heating material, a preparation method therefor, and an application thereof. The composite heating material comprises silicious ore powder and carbon-containing powder. The silicious ore powder comprises more than 97% of silicon dioxide. The carbon-containing powder is carbon crystal powder and comprises more than 90% of carbon. The composite heating material can work under a low voltage ranging from 12 to 110V, and the temperature can reach within 50 degrees centigrade after a temperature rise of 30 minutes, and the power per square meter is 15 to 48W. The composite heating material has the characteristics of being energy saving, environmentally friendly, has high thermal efficiency, and being safe in use. |
