Abstract
The present invention discloses electric heating paste which has the components (by weight) as follows: 100 portions of graphite, 20 to 70 portions of copper sulphate and 30 to 80 portions of water. The present invention is mainly used as electric heating materials for the heating of heat utensils, family residences and other building construction in the daily life. Compared with the existing electric heating coating materials, the present invention has the advantages of little power consumption and high thermal efficiency, and besides, the present invention is not limited by any objects (apart from electrical conductors) which need the materials.
Description
The invention provides a kind of Electric heating paste, this Electric heating paste is real in being the electric-heating coatings of electric conductor with the graphite powder, belongs to a kind of electroheat technology.
The still resistance wire energising heating that the heating of electrical heated appliance is generally used in the market, this heat hot efficient is low, and in addition, the time opens circuit for a long time easily.This novel conductive hot material of electric-heating coatings is familiar with by people gradually, and it will replace resistance wire, is a kind of innovation of domestic and international thermo electric material.Compare with the resistance-type heating wire, have heat efficiency height, easy to use, form and easily, not to be subjected to the restriction of material condition (removing electric conductor) body form, power saving, cheap.The Chinese invention patent communique discloses CN1068582 electric-heating coatings and technology, and its invention main points are: this electric-heating coatings is made up of carbon dust (graphite powder), shellac, diluent (ethanol).Shellac and diluent itself have increased the resistance of electrically-conducting paint, so when below safe voltage, working just during low voltage operating owing to electric current does not reach the raising that needed value scope influences the heat efficiency, must satisfy in the conductive current scope of 1.5A-2.5A and can generate heat for the graphite powder material in the electric-heating coatings, so need limit low resistance when using low-voltage, when using high voltage, need improve resistance, can reach the saving electric energy like this, satisfy the needs of different voltages and different purposes, but above-mentioned disclosed electric-heating coatings composition is impossible reach.
The objective of the invention is to overcome the deficiency in the above-mentioned coating technology, and providing a kind of composition more simple, application surface is more extensive, not conducted electricity very well by the restriction (removing electric conductor) of voltage and material therefor, little power consumption, a kind of Electric heating paste that the heat efficiency is high is a thermo electric material.
The objective of the invention is to realize with following technical measures:
Form by graphite powder, copper sulphate and water, its component by weight:
100 parts of graphite powders
Copper sulphate 20-70 part
Water 30-80 part
Graphite powder is basic electric conducting material, and copper sulphate heating earlier dissolves fully in water, and copper-bath has two purposes, on the one hand as the graphite powder diluent, and the 2nd, be used for increasing the graphite powder electric conductivity, reduce resistance.Graphite powder and copper-bath mixed becomes paste materials, the resistance of available then this material of Meter Test, resistance sizes is relevant with the voltage of use, the big resistance that requires of voltage is big, the little resistance that requires of voltage is also little, must guarantee that in a word electric current between 2.5A-1.5A, can make the Electric heating paste heating, improve the heat efficiency.So the increase of the resistance of Electric heating paste own is relevant with the concentration of minimizing and copper-bath, in use, in advance the Electric heating paste resistance sizes is measured according to used object and voltage swing, in fact just in the concentration of deployed copper-bath.The Electric heating paste brushing for preparing is on the insulation utensil and wall of needs heating, and the thickness of brushing is decided according to required caloric value, and voltage is decided according to the condition of using.Extraction electrode can be with metal forming and other electric conductor directly and Electric heating paste is bonding draws.
The present invention is mainly used in the heating of insulation utensil, as thermos cup, electric rice cooker, canteen etc.; Heat insulating material formed heating such as wall wallpaper, ceramics brick etc.When being used for insulation such as thermos cup, canteen utensil,, when the allotment Electric heating paste, need strengthen copper-bath concentration, to guarantee heat efficiency height and power saving owing to be subjected to the restriction of low-voltage.When being incubated on being used for wall, be coated on the ceramics as adding when producing the ceramics brick, this situation can be worked under the voltage of 220V, so voltage is big, need reduce copper-bath concentration when the allotment Electric heating paste, guarantees working properly.
Thermal stability height of the present invention, and in portioned product the life-span long, need not to repair, when both having made some materials after scribbling this product, occur partly damaging, but this Electric heating paste of coating continues to use, and has advantages such as power saving, heat efficiency height, price be low compared with other electric-heating coatings.
Below by embodiment technical essential of the present invention is further described specifically:
Certain when the object area, establish electric current when 1.5A, the resistance that is coated in the Electric heating paste on the object is as follows with change in voltage:
Voltage 30v 60v 110v 220v
Resistance 20 Ω 40 Ω 80 Ω 160 Ω
