Preparation method of electric heating writing pad

Abstract

The invention relates to a preparation method of an electric heating writing pad. The preparation method comprises the following steps of cutting a foaming sponge layer, an anti-skid rubber layer anda PU leather layer; (2) a wire arranging groove is punched in the middle of the foaming sponge layer, and the wire arranging groove penetrates through the whole foaming sponge layer; (3) the anti-skidrubber layer is adhered to the bottom surface of the foaming sponge layer through glue; (4) a heating wire is arranged in the wire arranging groove of the foaming sponge layer; (5) the PU leather layer is adhered to the surface of the foaming sponge layer through glue, so that a three-layer material composite body is formed; (6) performing external cutting and finishing on the body by utilizing apunch die; (7) standing and compacting the cut body; (8) the body which is fixed and compacted is connected with a controller and a plug. The preparation method has the advantages that the surface ofthe electric heating writing pad is flat, the surface is more resistant to high temperature, the using comfort is excellent, the service life is longer, and the electric heating writing pad is saferin the using process.

Description

Technical field [0001] The invention relates to the technical field of heating equipment, in particular to a preparation method of an electric writing pad. Background technique [0002] At present, the office heating devices on the market are mainly glass heating plates. Because of the strong thermal conductivity of glass, there will be a biting icy feeling after the human body comes into contact at room temperature. Moreover, because ordinary electric heating plates are made of glass, they are not only bulky, but also very inconvenient to transport. At the same time, its thermal conductivity and warmth retention effect are also very general. Summary of the invention [0003] The purpose of the present invention is to provide a method for preparing an electric writing pad with a smooth and flat surface, a comfortable hand feeling, and high safety in use in view of the defects of the existing electric heating devices for office use. [0004] In order to achieve the above technical ...

Problems solved by technology

[0002] At present, the office electric heating devices on the market are mainly glass electric heating plates. Because glass has strong thermal conductivity, the human body will feel icy cold after touching it at room temperature.

Moreover, because the common electric heating plate uses glass as the panel, it is not only bulky, but also very inconvenient to transport.
