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

[0032] Preparation of graphite carbon paste: It is prepared by mixing conductive graphite powder, glass powder, zinc powder, terpineol, ethyl cellulose and sodium silicate according to the weight ratio of 100:40:30:25:10:5.

Embodiment 1

[0034] 1) First fix one end of the copper strip 5 on the front surface of the first resin layer 1 (thickness is 0.2 mm) and extend the other end to the outside of the first resin layer 1;

[0035] 2) Then, the graphite carbon slurry is coated on the front surface of the first resin layer 1 to form a graphite layer 4 (thickness is 0.2mm), and one end of the copper strip 5 is coated on the graphite carbon slurry coating Inside;

[0036] 3) hot pressing the second resin layer 2 (0.2 mm in thickness) at a pressure of 13 MPa and 170° C. for 4 hours, and hot pressing on the graphite layer 4 to obtain a sandwich panel;

[0037] 4) hot pressing the mica paper 3 (0.2 mm in thickness) on both sides of the sandwich panel, and naturally cooling to obtain the flame retardant carbon crystal heating panel A1;

[0038] Wherein, graphite carbon paste is made by preparation example 1.

Abstract

The invention discloses a flame-retardant carbon crystal heating plate which is prepared by the following steps: 1) fixing one end of a copper bar on the front of a first resin layer, and extending the other end to the outside of the first resin layer; 2) brushing graphite carbon slurry on the front of the first resin layer to form a graphite layer, and coating one end of the copper bar in the graphite carbon slurry; 3) hot pressing a second resin layer on the graphite layer to obtain a sandwich plate; and 4) hot pressing mica paper on both sides of the sandwich plate, and naturally cooling to obtain the flame-retardant carbon crystal heating plate. The flame-retardant carbon crystal heating plate has the advantages of long-time uniform heating, high-pressure resistance, good heat resistance and safety in 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 ...
