Embodiment 1

[0015] A method for preparing a flexible graphite carbon crystal plate, characterized in that: the steps are:

[0016] 1) Grind and pulverize graphite to obtain carbon crystal particle powder with a size between 100-1000nm, and then mix it with 1% titanate coupling agent 201 in water to form a slurry;

[0017] 2) Cover and disperse the slurry obtained in step 1) on the high thermal conductivity nylon cloth as the base material;

[0018] 3) Coating an insulating layer of alumina silicon rubber on the outside of the plate obtained in step 2).

Embodiment 2

[0020] A method for preparing a flexible graphite carbon crystal plate, characterized in that: the steps are:

[0021] 1) Grind and pulverize graphite to obtain carbon crystal particle powder with a size between 100-1000nm, and then mix it with 1.5% titanate coupling agent 201 in water to form a slurry;

[0022] 2) Cover and disperse the slurry obtained in step 1) on the high thermal conductivity nylon cloth as the base material;

[0023] 3) Coating an insulating layer of alumina silicon rubber on the outside of the plate obtained in step 2).

[0024] The product prepared by the present invention has high insulation performance and rapid heating due to the use of alumina silicon rubber as the insulating layer. The board is generally brittle, and it is a new type of material that is widely used.

Abstract

The invention provides a preparation method of a flexible graphite carbon crystal plate and relates to a preparation method of a heating graphite carbon crystal plate. The preparation method comprises the following steps: taking graphite as a substrate; carrying out ball milling and grinding to obtain chopped fibers with the diameter of 9-20 microns and the length of 100-500 microns; crushing the chopped fibers to finally obtain carbon crystals with the sizes of 100nm-1000nm; uniformly dispersing the carbon crystal grains on high-heat-conduction nylon cloth and curing to form a plate; and finally, coating an aluminum silicon oxide rubber insulating layer on the surface of the carbon crystal plate. The preparation method has the advantages that on the basis of a conventional hard carbon crystal plate, a nylon cloth covering method is adopted so that the rigidity of the carbon crystal plate is greatly reduced and the carbon crystal plate is relatively convenient to use and has beautiful decoration; and aluminum silicon oxide rubber is used as the insulating layer so that the heat conductivity is improved. The product has the advantages of softness and cleanness, no pollution, high insulativity, good mechanical performance, puncture resistance, rapidness in temperature rising and long service life.

Description

technical field [0001] The invention relates to a preparation method of a heating and heating graphite carbon crystal plate, in particular to a preparation method of a flexible graphite carbon crystal plate. Background technique [0002] Carbon crystal electric heating plate is "carbon crystal electric heating low temperature radiation heating system". It is a new type of low-temperature radiation heating system developed with a carbon crystal heating plate as the core component. The heating principle of the carbon crystal electric heating plate: under the action of the electric field, the carbon molecular group in the heating element produces molecular motion, and there is severe friction and impact between the carbon atoms, and the heat generated is transmitted to the outside in the form of far-infrared radiation and convection. The conversion rate of electric energy and heat energy is as high as 98%. The carbon crystal electric heating plate system makes full use of the...
