Abstract

The invention relates to a heating pad for melting snow on roads. The heating pad mainly comprises an upper and a lower insulating layers for waterproofing and current leakage preventing, a fixed wrapping clothe layer, and a conductive heating fabric wrapped by the upper and the lower insulating layers. The conductive heating fabric is woven by conductive yarns as warps, and metal conductive wires as wefts. In addition, the conductive yarns each comprises a nonconductive axial yarn and a fine metal filament winding on the axial yarn. The fine metal filament winds outside the axial yarn to form a stretchable and flexible conductive yarn. Therefore, the woven conductive heating fabric is coated by an insulating layer made by rubber, plastic or silicone to form the heating pad having conductive heating effect. The heating pad can be applied on trails or lanes outside garages to melt snow in the winter outdoors.
