Problems solved by technology

The existing problems are not only high material cost and complex manufacturing process, but also the metal body dissipates heat too quickly, the temperature control effect is not good, and the decoration effect of the floor cannot be achieved.
[0003] In addition, the Chinese patent application with application number 200620028876.8 discloses an electric heating element for ground heat dissipation and heating. Although it overcomes the shortcomings of geothermal heating with water as the heat source, it needs to be equipped with electric heating wires and glass tubes to protect the heating wires. 1. The heat-conducting sand surrounding the glass tube and the tubular heat-conducting shell outside the heat-conducting sand constitute the heating device. Not only is the structure still complex, the manufacturing process is cumbersome, and it is impossible to ensure uniform heating in areas with different distances from the electric heating, and the lead-out structure of the power line is not convenient for decoration and installation.

Embodiment 1

[0026] The basic structure of the self-heating plate of this embodiment is as follows: figure 1 As shown, it includes a heat conduction panel 2 made of non-metallic material and a heat storage bottom plate 3. The heat storage bottom plate 3 has two sets of insertion holes 6 with built-in electrodes 5 spaced along the length direction. The upper surface of the heat storage bottom plate 3 is attached with a The metal current-carrying bar 4 (aluminum foil, copper foil or other metal foil with a thickness of 0.02-0.2 mm) in electrical contact with the built-in electrode 5 in the insertion hole 6 is inserted between the heat-conducting panel 2 and the heat storage bottom plate 3 by embedding the current-carrying bar 4 The conductive heating adhesive layers 1 are adhered to each other.

[0027] The optimal structure of built-in electrode 5 sees figure 2 , image 3 with Figure 4 As shown, it is made of an elastic metal sheet, and the elastic metal sheet has a horizontal position...

Embodiment 2

[0036] The basic structure of the self-heating plate of this embodiment is as follows: Figure 5 As shown, the basic structure and process are the same as the first embodiment, the difference is that the upper surface of the heat conduction panel 2 and the lower surface of the heat storage bottom plate 3 are respectively attached with a decorative layer 2-1 made of impregnated paper and a balancing layer 3-1.

Embodiment 3

[0038] The basic structure of the self-heating plate of this embodiment is as follows: Image 6 As shown, the basic structure and process are the same as those of the second embodiment, the difference is that a wear-resistant layer 2-2 is attached on the upper surface decoration layer 2-1 of the heat conduction panel 2 .

Abstract

The invention belongs to the technical field of electric heating materials, and relates to a self-heating board and a manufacturing method of the self-heating board. The self-heating board comprises a heat conducting face board and a heat storage bottom board both made of nonmetal materials, the heat storage bottom board comprises at least one set of inserting holes which are provided with electrodes inside and distributed in the length direction at intervals, metal current carrying bars in electric contact with the internal electrodes in the inserting holes are attached to the upper surface of the heat storage bottom board and extend in the length direction, and the heat conducting face board and the heat storage bottom board are bonded by embedding the current carrying bars in conductive and heating glue layers. Conductive and heating glue is reasonably utilized, lead devices are ingeniously arranged, the types of raw materials are not added, original basic technology facilities do not need to be changed, the manufacturing method of the self-heating board is simple, and the self-heating board is stable in structure, good in conductive and heating performance, high in thermal efficiency, even in heating, high in combination strength, safe and reliable, wide in application range and capable of being used as floors, wallboards, decoration boards and the like, and meets relevant standards of artificial boards.

Description

technical field [0001] The invention relates to a self-heating board, in particular to a self-heating board made of conductive heating glue, and also relates to a manufacturing process thereof, which belongs to the technical field of electric heating materials. Background technique [0002] In recent years, floor heating decoration has been rapidly popularized. The Chinese patent application with the application number 200410052177.2 discloses a typical heating floor. The heating floor uses metal as the body. The upper and lower surfaces of the metal body have a layer of wear-resistant coating, and the bottom surface of the metal body has a layer of wear-resistant coating. Electric heating film. According to actual needs, a layer of filler can be added on the bottom surface of the electric heating film layer. The existing problems are not only high material cost and complex manufacturing process, but also the metal body dissipates heat too quickly, the temperature control ...
