Problems solved by technology

[0002] Electric heating plates have the advantages of energy saving, comfort, and far-infrared health care in use, so they have been widely promoted and used, and their production technology has also been developed rapidly. However, there are fatal shortcomings in the design of electric heating plates on the market. Can not solve the contradiction between super insulation and super heat dissipation of carbon material electric heating plate, there are safety hazards in use
In the past, when the heating element of the electric heating plate was used in a humid environment or soaked in water, the leakage current increased due to the conductivity of the water, causing the electric heating plate to leak. The leakage protector would block the current after detecting the leakage, so that the electric heating plate could not work Therefore, in some areas (especially in coastal and southern areas), traditional electric heating devices cannot be used on wet floors such as floor tiles, cement, and wet toilets, or electric leakage protectors are not installed when using electric heating, and there is a serious danger of electric leakage during use Therefore, some manufacturers suggest that heating electric heating panels should not be used on concrete floors, but only on wooden composite floors, but this limits the use of this new high-tech heating product in home heating, and also hinders the development of electric heating technology

Abstract

The present invention discloses an acid, alkalis and salt resistant moisture-proof electric heating board applied in cement and humid climates and method for producing the same. The moisture-proof electric heating board in multi-layer structure, includes a heating element; a waterproof heat conducting layer packaging the heating element; a glass fiber layer, located between the heating element and the water proof heat conducting layer, wherein, one external surface of the water proof heat conducting layer is provided with a heat-insulating layer while the other external surface can be provided with a decorative layer. The producing method includes: firstly inlaying electrodes at the symmetrical margins of the conductive paper; making the heating element packaged with the glass fiber layer into a plate blank under high temperature and high-pressure; casting a waterproof agent at the surface of plate blank to constitutes a water proof heat conducting layer; and then laying a heat-insulating layer at one external surface of the water proof heat conducting layer and laying a decorative layer at other external surface. The electric heat board produced by the invention has advantages of moisture-proof and damp-proof, wider application than traditional electric heat board, safe use and low cost.
