Abstract
The invention relates to an electric ceramic cooker thermal-insulation layer and a preparation method thereof. The thermal insulation layer is prepared by the preparation method comprising the following steps: mixing silicon dioxide, titanium dioxide, iron sesquioxide, aluminum oxide and fiber cotton which is produced from profundal rock by using wire blow molding; then performing compression molding in a new compression molding mode; and finally, drying under the environment of 200-300 DEG C. The method is higher in shaping rate, higher in yield and lower in mechanical equipment and production cost compared with the prior art.
Description
Technical field
The present invention relates to a kind of insulating layer of electric ceramic furnace, particularly a kind of insulating layer of electric ceramic furnace and preparation method, belong to electric furnace insulation production technical field.
Background technology
Electricity pottery stove is the top product of current kitchen appliance stove and accessory, is the electromagnetic oven that more often uses of current kitchen and the upgrade version of light-wave cooker, and it has abandoned the shortcoming of electromagnetic oven and light-wave cooker, has retained its advantage, and has transformed, and is comparatively advanced person's kitchen stove and accessory of the whole world.In highly pursuing the developed countries such as America and Europe of safety, environmental protection, health, electricity pottery stove accounts for leading market in household electrical appliance kitchen range, believes in the near future, and Chinese family also can make electricity consumption pottery stove gradually.
The thermal insulation layer that on the electrothermal disk of electricity pottery stove, operated by rotary motion has ceramic fiber material to make, heat nichrome wire being produced by thermal insulation layer concentrates in together, and adds the pan on black brilliant plate, and thermopair is installed simultaneously on electrothermal disk, by the temperature in sensible heat galvanic couple thoughts and feelings electrothermal disk, control electrothermal disk work.
The choice relation of insulation layer thickness, to the problem of energy-conservation and cost, still in today of All-round, Coordinated and Sustainable Development, considers insulation layer thickness from economy and environment two aspects, should be more reasonable, and meaning is more great.
Now, whole world heat preserving and insulating material just protects integrated future development outward towards efficient, energy-conservation, thin layer, heat insulation, waterproof, at Development of Novel heat preserving and insulating material and meet structural thermal insulation power-saving technology simultaneously, more emphasize to use targetedly heat-insulation material, by standard specifications design and construction, make great efforts improve insulating efficiency and reduce costs.
Traditional heat preserving and insulating material is to improve gas phase voidage, and it is main reducing thermal conductivity and transmissibility factor.Fiber-like lagging material will make transmission of heat by convection and radiative transfer raise in environment for use, must have thicker coating; And section bar class inorganic heat insulation material will carry out assembling construction, exist seam many, damage the defects such as attractive in appearance, water-repellancy is poor, work-ing life is short.For this reason, people are seeking always and are studying a kind of type material that can greatly improve lagging material heat insulating reflecting performance.
The ceramic fiber material using on the electrothermal disk of electricity pottery stove is at present all rigid structure, and density is large, weight is large, and the bottom surface of micro-crystal plate is again concavo-convex coarse rigid face, certainly leads to numerous gaps when both engage; And while nichrome wire being installed on electrothermal disk at present, need offer through hole in chassis and the thermal insulation layer side of electrothermal disk, can make the circuit pin of nichrome wire stretch out electrothermal disk from through hole.These ask the heat localization effects that gap and through hole have reduced electric pottery stove undoubtedly, have affected the capacity usage ratio of product.
Summary of the invention
The object of the invention is to overcome the shortcoming existing in prior art, the invention provides a kind of quality is light, flexible, thermotolerance is strong, easily manufactured novel silicon-dioxide and cellucotton lagging material and manufacture method thereof.
The object of the invention is to be achieved through the following technical solutions:
An insulating layer of electric ceramic furnace, this thermal insulation layer is comprised of the component of following weight part:

Total umber of described silicon-dioxide, titanium dioxide, titanium dioxide two iron, alumina material is 60-100 part; Total umber of described silicon-dioxide, titanium dioxide, titanium dioxide two iron, alumina material is 85 parts; The optimum proportion that described dark bedstone rock accounts for the weight ratio of total material is 30 parts; The density of described silicon-dioxide, titanium dioxide, titanium dioxide two iron, alumina material is 0.4kg/cm
2~ 0.8kg/cm
2; The optimum density of described silicon-dioxide, titanium dioxide, titanium dioxide two iron, alumina material is 0.6kg/cm
2;
A preparation method for insulating layer of electric ceramic furnace, comprises the steps:
(1) take silicon-dioxide 30-50 part, titanium dioxide 5-15 part, titanium dioxide two iron 5-15 parts, aluminum oxide 10-30 part, dark bedstone rock 20-40 part, dark bedstone rock employing is blown to a cellucotton of producing and mix with other raw material stirring even, standby;
(2) compound of step (1) gained is carried out to die cast at normal temperatures;
(3) product after step (2) die cast is dried and be get final product under the environment of 200-300 ℃;
The insulation layer thickness of described die cast is 1-2mm.
The invention has the beneficial effects as follows: ceramic fiber lagging material quality of the present invention is light, thermotolerance is strong, and high resilience, uneven surface and its sealing engagement that can adapt to micro-crystal plate, can clamp the circuit pin of nichrome wire simultaneously, avoid perforate on thermal insulation layer, effectively improve heat concentration degree and the utilization ratio of electrothermal disk, be conducive to improve the buffering pressure relief capability of micro-crystal plate simultaneously; Not only high resilience of fiber insulation layer of the present invention, and use continuously under the environment of approximately 1300 ℃, can not be out of shape good heat resistance yet.
