Description
Technical field
The present invention relates to glaze preparation fields more particularly to a kind of red copper glaze and preparation method thereof.
Background technology
Red copper glaze is super-low expansion glaze, and exclusive cooperation low bulk green body uses.At present, substantial amounts of thermal-resisting ceramic vessel,
It is light glaze in pot class product；And this kind of ceramic pot, pot class product are after the medium for extended time such as storage water, it may appear that infiltration
Situations such as, unstable product quality.For this purpose, a kind of impermeable and glaze paint dumb light the low expansion ceramic glaze of exploitation is existing market
Blank.
The content of the invention
Therefore, for it is above-mentioned the problem of, present invention aims at provide a kind of red copper glaze and preparation method thereof, the red copper glaze
Glaze is colour-stable, glaze paint dumb light, high yield rate so that product obtained is impermeable, resistance to rapid heat cycle.
To achieve these goals, the technical solution adopted in the present invention is：
A kind of red copper glaze, technical recipe are calculated by mass percentage, are made of following component with content：Lithium feldspar powder 54-67%,
Talcum 4-11%, kaolin 3-11%, zinc oxide 1-4%, barium carbonate 2-6%, quartz 5-10%, potassium feldspar 1-6%, iron oxide 2-5%.
The present invention breaches the limitation of traditional glaze, the adjustment being made up of glaze, and the obtained coefficient of expansion is low, heat impact strength is good
The good, glaze of glaze paint dumb light；And the glaze and the good combination of green body, product are impermeable.
Another object of the present invention is to provide a kind of preparation method of above-mentioned red copper glaze, each component is weighed by formula
After be sufficiently mixed add in grinding pot in, add in be equivalent to dry powder weight 45%-50% moisture be ground 12-15 it is small when,
Middle material：Ball：Water ratio is 1:1.5:0.65, the good concentration of glaze slip of ball milling is then adjusted to 48 ± 1 degree of true specific gravity, hand is decorated with glaze spraying
Method glazing is on green body, glazed thickness 1mm -1.5mm, again into carrying out 8-11 with 1230 DEG C -1250 DEG C of temperature in kiln after drying
The oxidation of hour is burnt till, the kiln discharge after natural cooling, and the red copper glaze is made.
As one of above-mentioned preparation method preferred embodiment, when adding water grinding 12-15 small after carry out testing graininess, granularity is surveyed
325 mesh sieves were tried, glaze slip screen over-size is in 0.1%-0.3%.
As one of above-mentioned preparation method preferred embodiment, the heating that the oxidation is burnt till is divided into three phases, first rank
Section：Room temperature controls 3 DEG C/min of heating rate, second stage to 650 DEG C：650-1050 DEG C, 3.5 DEG C of heating rate of control/
Min, three phases：1050-1250 DEG C, 2 DEG C/min of heating rate is controlled, until during maximum temperature, keeps the temperature 30min.
The principle that the present invention realizes is：The raw material for selecting spodumene, these coefficients of expansion of lithium feldspar low, by the body of glaze
The coefficient of expansion is controlled 100 × 10-7Within, make it that there is relatively uniform expansion character with green body；On this basis introduce magnesium,
The materials such as barium, zinc are adjusted, and realize magnesium-aluminium-silicon three-phase congruent melting, and glaze water is enable to be melted at 1230-1250 DEG C, good with green body
With reference to product is made to reach impermeable effect；The addition of appropriate iron oxide can widen the firing range of glaze, improve high temperature and glue
The parameters such as degree, elasticity.In addition, by the control of green body water absorption rate below 3%, make glaze melting that can there is good knot with green body
It closes.By controlling the melting temperature of glaze, it is specially the reasonable sial proportioning of lithium minerals and clay minerals, is in glaze water and begins
Melt temperature range or so, to ensure glaze paint matte effect.
