The invention discloses an integrated silicone rubber composite cloth heating body. The integrated silicone rubber composite cloth heating body takes a piece of intermediate fabric with a heating function and two pieces of surface fabric jointed with the two sides of the intermediate fabric as a framework; the intermediate fabric and the surface fabric are respectively and internally filled with an integrated silicone rubber material; an integrated fabric composite structure is formed by the framework and the silicone rubber. The intermediate heat-generating fabric and the surface fabric in the integrated silicone rubber composite cloth heating body are highly combined together in the aspect of molecular structure, so that the stretching resistance and delamination resistance of the silicone rubber composite cloth heating body are enhanced, and the technical problems of loss of the heating function and short service life due to delamination and shifting which occur between fabric layers in the use process of the existing silicone rubber composite cloth heating body are effectively solved. By virtue of the stable molecular bonding force between the intermediate heat-generating fabric layer and the surface fabric layers, the heating property of the silicone rubber composite cloth heating body is enabled to be stable, and the heat distribution of the silicone rubber composite cloth heating body is enabled to be uniform.
