Abstract
The invention discloses a double-layer ceramic thermal insulation cup and a preparation method thereof. The double-layer ceramic thermal insulation cup comprises an inner layer structure and an outer layer structure, and a hollow part is arranged between the inner and outer layers. The preparation method comprises the following steps of: adding water into dolomite with stirring, pulping, grouting, demolding, performing calcination for the first time after certain humidity is achieved, unloading from a kiln, cooling, polishing, applying chromophore, air-drying, applying a transparent glaze, performing calcination for the second time, unloading from the kiln, and keeping the temperature. The double-layer ceramic thermal insulation cup has a good thermal insulation and heat preservation effect, is cleaner, healthier and more attractive than products made of other materials, and is rich in characteristics.
Description
The present invention relates to a kind of heat insulation cup, relate to a kind of double-layered heat-isolating ceramic cup specifically, the invention still further relates to the preparation method of this double-layered heat-isolating ceramic cup with inside and outside double-layer structure.
Water tumbler often is used in daily life as daily necessities, common have stainless steel cup, glass, a ceramic cup etc., the user can select the cup of unlike material according to different needs for use, wherein glass and ceramic cup since the thermal conductivity factor of its cup material less than stainless steel, heat insulation effect is better than stainless steel cup, but also comes with some shortcomings a little.As when pouring high-temp liquid into, because of conductive force after a period of time, the cup temperature also raises gradually, be not easy to the empty-handed cup of taking, and for example, when ambient temperature is higher, same owing to the conductive force between the liquid and the external world, an ice-cold fluid temperature can raise gradually in the cup, does not reach the satisfied effect of drinking.
Developed the double thermal insulation cup according to above problem dealer, at present commercially available have the heat insulation cup of double glazing, a stainless steel cup etc.The problem that exists is owing to material, and double-layered stainless steel cup is difficult for making, and can only make simple shape, and cost is also high.Above-mentioned in addition two kinds of cups all do not have handle, and it is not too convenient to use, and the more important thing is that tea flavour is impure when making tea with this kind cup, far away from bubble out next tea flavour perfume (or spice) with ceramic cup.And very strict manufacturing in the process of heat-isolating ceramic cup owing to requirement to relevant technology index, often do not reach satisfied effect.
The object of the present invention is to provide a kind of double-layered heat-isolating ceramic cup, form by selecting proper raw material, under appropriate processing condition, firing, a kind of have heat insulation preferably and heat insulation function promptly are provided, and cleaning, health, attractive in appearance, featured double-layered heat-isolating ceramic cup.
The present invention is achieved in that a kind of double-layered heat-isolating ceramic cup, it is characterized in that comprising inside and outside double-layer structure, and is provided with hollow bulb inside and outside between two-layer, and the cup side also can be provided with handle in addition.
The method for preparing double-layered heat-isolating ceramic cup of the present invention is characterized in that comprising the following steps:
1) adds that water stirs in the dolomite clay, begins slip casting, the demoulding after the making beating;
2) after pasting handle and airing, the cup side carries out burning till the first time;
3) kiln discharge is lowered the temperature, is polished and goes up color base, dries the back and goes up clear frit;
4) carry out burning till the second time.
It is 25～30% of gross weight that another feature of preparation method of the present invention is to add water in the step 1) water content.
The another mould that uses in the step 1) that is characterised in that of the present invention is to make mould with sulphur earlier, and then system strips out plaster mold.
Humidity when pasting handle the preparation method's of the present invention another step 2 that is characterised in that) is in 15～20% scopes.
Preparation method of the present invention one is characterised in that step 2 again) in the temperature of burning till for the first time be controlled in 950～1000 ℃ of scopes, the time of burning till is 4～5 hours.
The preparation method's of the present invention another temperature of burning till for the second time in the step 4) that is characterised in that is controlled in 900～950 ℃ of scopes, and the time of burning till is 7～9 hours.
The dolomite clay that adopts among the preparation method of the present invention is 6
#Dolomite clay, used color base are the crimson color base of tea.
Double-layered heat-isolating ceramic cup of the present invention can be made into different shapes by adopting different moulds, as toy or cartoon people etc., to satisfy different consumers' aesthetic requirement.
Advantage of the present invention is that the double-layered heat-isolating ceramic cup of producing has heat insulation preferably and heat insulation function, and than product cleaning, the health, attractive in appearance of other material, and be rich in characteristic.Simultaneously can also be according to application target, and design and produce out different ceramic products by moulding, flower face etc.
The present invention is further detailed explanation below in conjunction with accompanying drawing and embodiment.
