Description
The present invention is a kind of heating power type coating, can be used for preparing electric heating device.
Since the sixties, states such as American and Britain, day begin to develop electric-heating coatings, mainly make binding agent by silicate and organic high molecular polymer, add carbon black, graphite or metal powder and make electrically conducting coating, also claim electricity heating lacquer, but heating temp is not high, otherwise rete is easily played arcing and is ruined during energising.The electric-heating coatings of Chinese patent application 91105619.X and 92106309.1 SEPARATE APPLICATION, by binding agent, thinner and formulated based on the electro-conductive material of carbon black or graphite have characteristics such as film-forming process is simple, cost is low, but heating temp is restricted all.For improving the heating temp and the heat conduction efficiency of electric-heating coatings, it mainly is that silicate, electro-conductive material are graphite that Chinese patent application 94116361.X provides a kind of binding agent, be aided with the electric-heating coatings that some high temperature materials are made, its the highest heating temp is 380 ℃, and stabilized operating temperature is below 300 ℃.
It is low to the objective of the invention is to overcome existing electrothermal paint binding agent heatproof, rete is easily played arcing and is ruined, thereby the limited shortcoming of heating temp, by with water-soluble phosphate as binding agent, improve the binding agent thermotolerance, change the corresponding composition of additive simultaneously, provide a kind of heat conduction efficiency good, adhere to firm electrothermal high-temp coating.
For realizing purpose of the present invention, electrothermal high-temp coating of the present invention is made of electro-conductive material, binding agent, thinner and additive uniform mixing, and raw material by the weight proportion of composition is:
Electro-conductive material 100
Binding agent 100-500
Thinner 0-500
Additive 20-250
Wherein electro-conductive material is carbon black, graphite, metal-powder or their mixture, binding agent is a water-soluble phosphate, thinner is water or sodium-chlor, saturated potassium chloride solution, additive comprises that solids is powdered material in metal oxide, metal chloride, the raw material, and granularity is less than 200 μ m.
Specifically, can be dihydrogen phosphate, monohydric phosphate as the water-soluble phosphate of binding agent, or boron aluminate or phosphate, aluminum phosphate magnesium solution, or described these mixtures of material.The weight proportion that comprises composition in the additive is:
Titanium dioxide, aluminium sesquioxide or its mixture 10-150
Antimonous oxide 2-20
Chromium sesquioxide, chromic salt or chromic acid 0-20
Sodium-chlor or Repone K 8-100
Wherein titanium dioxide, aluminium sesquioxide have anti-conducting particles oxidation susceptibility, can improve the temperature tolerance of rete; Antimonous oxide has flame retardant properties; Chromium sesquioxide, chromic salt or chromic acid can be alleviated the corrosion of coating to metal electrode, and sodium-chlor or Repone K can reduce coating resistivity, strengthen electroconductibility.
Electrothermal high-temp coating of the present invention, the heating temp of the existing similar electric-heating coatings of big quantum jump, the highest heating temp can reach 700 ℃, and stabilized operating temperature can reach 450 ℃-550 ℃.It is simple to use the present invention to prepare various heater members technologies, can directly brush as paint, also can blade coating, spraying, dip-coating, roller coating or be screen-printed on the isolator of Any shape, ooze silver slurry coating etc. as conductive electrode with copper sheet, copper mesh or baking, promptly can be made into the electrical heating element of different shape, specification, the power of electrical heating element can be adjusted according to the rete thickness that is coated with, geometrical shape, structure, area size and two distance between electrodes, also can control power, thereby reach the purpose of control coating heating temp by pressure regulation.After another advantage of the present invention was the coatingsurface drying, curable 250 ℃ of-350 ℃ of bakings, if the coating heating temp of design is higher than 250 ℃, after the surface drying, the self-heating of can switching on solidified.Electrothermal high-temp coating of the present invention is applicable to the direct current and the voltage of alternating current of 6-380 volt.
