Description
Technical field
The present invention relates to the oil paint of a kind of electromagnetic oven with vessel, especially a kind of electromagnetic oven is with the oiliness electromagnetic induction coating of vessel.
Background technology
Electromagnetic oven more and more receives human consumer's favor because of characteristics such as it is efficient, energy-saving and environmental protection.Electromagnetic oven is used electromagnetic induction principle food is heated.The boiler face of electromagnetic oven is the heat-stable ceramic plate, and exchange current produces magnetic field through the coil of ceramic plate below, and when the magneticline of force magnetic field in passed bottom such as iron pan, Stainless Steel Kettle, the generation eddy current made the bottom of a pan generate heat rapidly, reaches the purpose of heat food.
Because the non-magnetic material can not effectively converge magneticline of force, almost can not form eddy current, so do not heat basically; In addition, the magneticsubstance that conductive capability is poor especially is because its resistivity is too high, and the eddy current of generation is also very little, can not fine generation heat.So the pot body material that electromagnetic oven uses is that conductivity is better relatively, the metal of ferromagnetic substance or alloy and their complex body.The human consumer simultaneously also preference use the pottery pot of high insulating effect, lightly how other cooking utensils such as aluminum pot easily are applied to electromagnetic oven with these cooking apparatuss, become the problem that presses for solution.
It is raw material with the silver hydroxide that CN1448453A discloses a kind of, the method for the electromagnetic induction exothermic paint through prepared such as ball milling, thickening, aging and stirrings; CN200610019686 discloses a kind of magnetic resonant heating film that has, and through processes such as ball milling batching, die, pad pasting, decoration firings film is attached to the bottom that is heated of pottery, realized the use of pottery on electromagnetic oven, but the course of processing is comparatively loaded down with trivial details.It is the preparation method of the electromagnetic induction exothermic paint of raw material with silver hydroxide and silver suboxide that CN1648174A discloses a kind of, realized pottery and the use of glassware on electromagnetic oven, but technology is consuming time, and cost is higher.CN200610048896 discloses a kind of electromagnetic heating spray coating liquor, is implemented in the application on the electromagnetic oven through outside or the inner bottom surface that metal spraying liquid is sprayed to cooking ware.But this technology is not easy to control coating thickness, the problem of membrane thickness unevenness can occur, causes in the use food inequality of being heated.Sprayed coating and vessel surface fastness are not enough simultaneously, come off easily.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, the oiliness electromagnetic induction coating of a kind of electromagnetic oven with vessel is provided, preparation technology is simple, and is with low cost, and coating combines fastness high with vessel surface, but life-time service is safe and practical.
According to technical scheme provided by the invention; Said electromagnetic oven is with the oiliness electromagnetic induction coating of vessel; Characteristic is, comprises following component, and the component ratio is counted by weight: 8 ~ 12 parts of silver powder, 2 ~ 4 parts of boron glass powder, 2 ~ 5 parts of iron powders, 5 ~ 10 parts of tackiness agents, 20 ~ 30 parts of organic solvents.
The mass ratio of said organic solvent and tackiness agent is 70 ~ 85:15 ~ 30.
Said tackiness agent is polyvinyl butyral resin and/or TKK 021.
Said organic solvent is Terpineol 350, phenyl ether or glycerine.
Said iron powder particle diameter is 100 ~ 400 orders.
Coating according to the invention can be used for non-magnetic materials such as pottery, glassware, and applying the back vessel can use on electromagnetic oven.Preparation technology of the present invention is simple, and storing temperature is low, and save energy adds iron powder in the raw material, effectively reduced cost; Coating thickness is even and thin, and heating efficiency is high, and heat supply is even; Coating combines fastness high with vessel surface, but life-time service is safe and practical.
Embodiment
Below in conjunction with specific embodiment the present invention is described further.
Silver powder used in the present invention is the excellence conductor of heat and electricity, and chemicalstability is high, though under hot conditions also not with airborne oxygen reaction, made silver slurry wettability, printing are good, the sintering film-forming properties is good.
Boron glass powder staple used in the present invention is silicon-dioxide, boron trioxide, sodium oxide, aluminum oxide and potassium oxide.The boron glass powder can reduce refractoriness in tackiness agent, impel the formation vitreum, increases the flowability and the wettability of tackiness agent, and tackiness agent is evenly distributed around powder granule, reduces the contraction of tackiness agent, improves the cohesive strength of powder granule and body material.
Iron powder particle diameter used in the present invention is 100 ~ 400 orders, can be dispersed in uniformly in the slurry, and simultaneously iron powder also has good electromagnetic induction performance, and the adding of iron powder can partly substitute silver powder, and the consumption of minimizing silver powder effectively reduces cost.
Tackiness agent used in the present invention is polyvinyl butyral resin and/or TKK 021; Polyvinyl butyral resin has the higher transparency, winter hardiness, shock-resistant, anti-uv irradiation, with metal, glass, timber, pottery, fibre product etc. good cohesive force is arranged.Based on its good wettability, wet strength and when 300 ~ 400 ℃ of temperature, do not form corrosive gases and do not have residue and decompose well, polyvinyl butyral resin is particularly suitable for doing the sticker of printing-ink.
