Integrated electric heating plate and preparation method

Abstract

The invention discloses an integrated electric heating plate and a preparation method. The integrated electric heating plate comprises a heat preservation substrate, a heating film layer and a surfacelayer. The thickness of the heating film layer ranges from 50 nm to 10 [mu]m; and the square resistance of the heating film layer is in a range of 10 ohms / square and 1000 ohms / square. The heating film layer is made of oxide or oxysulfide, and the material of the heating film layer is one or more selected from the group consisting of ZnO<x>S<1-x>, InO<x>S<1-x>, Sn<x>In<1-x>O, Zn<x>Mg<1-x>O and Zn<x>Al<1-x>O; preferably, the heating film layer is a carbon-oxygen compound and the material of the heating film layer comprises SiO<x>C<1-x>, or the heating film layer is a carbon-nitrogen compound and the material of the heating film layer comprises SiC<x>N<1-x>. Conductive metal strips are attached to the two sides of the surface of the heating film layer and close to the edges, so a power supply circuit is formed. The integrated electric heating plate is small in heating material consumption, stable in heating material performance, high in heating efficiency and stable in heating power in the using process.

Description

technical field [0001] The invention relates to a building material, in particular to an electric heating integrated board and a preparation method thereof. Background technique [0002] At present, there are no effective heating measures in winter in southern my country, which is cold and humid in winter; although there are heating measures in the north, the air pollution during the heating process is serious. With the increasingly severe environmental pollution and energy crisis, the country is currently vigorously promoting coal-to-electricity in order to save energy and reduce emissions. But for northern users, the way of centralized heating makes the heating equipment still running when the user leaves the house, and the energy loss is serious; for southern users, there is currently a lack of efficient heating means. [0003] The electric heating integrated board is a brand-new heating product. It can emit 5-15μm far-infrared rays after being powered on. The 5-15μm far...
