Problems solved by technology

[0003] At present, the shell plates of most carbon crystal heating plates are epoxy resin plates. Although the resin plate has good heat resistance, it is prone to the danger of a sharp increase in temperature when the carbon crystal heating plate works for a long time or is heated by high voltage. This requires the carbon crystal heating plate to have good high temperature resistance and flame retardancy

Abstract

The invention discloses a flame-retarding carbon crystal heating plate. The flame-retarding carbon crystal heating plate comprises: (1) one end of a copper bar is fixed on a front surface of a first resin layer and the other end of the copper bar extends to the outer part of the first resin layer; (2) graphite carbon slurry is brushed on the front surface of the first resin layer to form a graphite layer, and the graphite carbon slurry covers one end of the copper bar; (3) a second resin layer is hot-pressed on the graphite layer to form a sandwiched plate; (4) mica paper is hot-pressed on two faces of the sandwiched plate, and the sandwiched plate is naturally cooled to obtain the flame-retarding carbon crystal heating plate. The flame-retarding carbon crystal heating plate provided by the invention can generate heat uniformly for long time, has good high-pressure resistance and heat resistance and is safe to use.

Description

technical field [0001] The invention relates to a carbon crystal heating plate, in particular to a flame-retardant carbon crystal heating plate and a preparation method thereof. Background technique [0002] Carbon crystal heating plate is made by adding far-infrared emitter and temperature-limiting agent into microcrystalline particles, and is made by special process and preparation technology. It is suitable for home heating, office building heating, school dormitory office building, storefront heating, central heating auxiliary heating, chess room, hospital, hotel, hotel, bath center, greenhouse insulation, warehouse insulation, etc. [0003] At present, the shell plates of most carbon crystal heating plates are epoxy resin plates. Although the resin plate has good heat resistance, it is prone to the danger of a sharp increase in temperature when the carbon crystal heating plate works for a long time or is heated by high voltage. This requires the carbon crystal heating ...
