Abstract

The invention relates to a green body of red soil ceramic. The green body of the red soil ceramic is prepared from the following raw materials: red soil, quartz, talc, limestone and dolomite; the transmutation glaze of the red soil ceramic is prepared from the following raw materials: potassium feldspar, albite, calcium oxide, barium oxide, kaolin, quartz powder, sodium tripolyphosphate, titanium oxide, rutile, zinc oxide and a coloring agent. By addition of other mineral raw materials, chemical raw materials and the like, the physical performance and the chemical performance of the green body are changed and the technical problems that the green body glaze of the red soil product is difficult to combine and the product is loose and fragile are solved; the firing temperature of the glaze is reduced from 1,310 DEG C to 1,230 DEG C, so thatthe firing temperature is reduced by 80 DEG C, the using amount of the fuel and the discharge quantity of harmful gas are reduced, environmental protection is contributed and production cost is greatly saved; and by development of the lead-free transmutation glaze, the lead-free transmutation glaze is suitable for being combined with the green body of the red soil ceramic, so that the problem of pollution to the ceramic decorative environment is solved fundamentally.

Description

The base substrate of red soil pottery and the formula of furnace transmutation glaze thereof
Technical field
The present invention relates to the formula of a kind of ceramic body and cover-coat enamel thereof, refer to especially a kind of base substrate of red soil pottery and the formula of furnace transmutation glaze thereof.
Background technology
The main raw material Red Earth Resource of laterite base substrate is abundant, the good and easy-formation of plasticity, and firing range is wide, can be from 1000 ℃ to 1250 ℃, but most of laterite is because of the directly glazing of reason of its coefficient of expansion, and the Chemical Composition of laterite is mainly 52.78% SiO 2, 33.57% Al 2O 3, 10.43% Fe 20 3, 3.16% K 2O, 0.06% Na 2O。Only take the raw material of laterite as the preparation base substrate, its SiO 2Content is on the low side, Al 2O 3, Fe 2O 3Content is higher, is unfavorable for the formation of silicate compound; K 2O, Na 2The biscuiting temperature of O content major effect base substrate, too high levels, the base substrate firing temperature is reduced and be unfavorable for the formation of cristobalite, can reduce the base substrate coefficient of expansion, affect the base glaze in conjunction with and produce glaze and split defective, quartz, potassium felspar sand, mullite are arranged, glassy phase and pore etc. in the mineral composition because of base substrate, wherein glassy phase is few, therefore the base substrate porous.
In addition, because the chemical constitution difference of the glaze of existing red soil pottery is larger, the coefficient of expansion of glaze is higher, and the firing temperature of glaze also reaches the height of 1310 ℃, very easily produces early stage glaze and splits, and spent fuel is also larger, and production cost is higher; For this reason, glaze is usually to contain lead solution as solvent, and apply the larger lead of elasticity one boron glaze on red soil greenwave body, this can offset the harmful effect that the thermal expansion of base glaze causes within the specific limits, but this also makes product have the excessive shortcoming of lead release, causes product not use on domestic ceramics.
Summary of the invention
The invention provides a kind of base substrate of red soil pottery and the formula of furnace transmutation glaze thereof, be not easy glazing, easily produce that glaze splits, the base substrate porous with what the base substrate that overcomes existing red soil pottery existed, and the firing temperature that red soil bristol glaze material exists is high, the problems such as early stage glaze splits, the product lead release large, can not use on domestic ceramics very easily occur.
The present invention adopts following technical scheme:
Red soil greenwave body, the preparation of this base substrate comprises following raw material: laterite, quartz, talcum, Wingdale, rhombspar; More specifically, the raw materials of this base substrate comprises following component: 49.3% SiO 2, 26.3% Al 2O 3, 2.1% Fe 20 3, 1.6% K 2O, 1.9% MgO, 18.8% CaO.
Red soil pottery furnace transmutation glaze, the preparation of this glaze comprises following raw material: potassium felspar sand 35-40 part, albite 22-25 part, calcium oxide 8-15 part, barium oxide 15-20 part, Longyan kaolin 8-15 part, silica powder 6-12 part, tripoly phosphate sodium STPP 0.2-0.4 part, titanium oxide 10-20 part, rutile 2-10 part, zinc oxide 3-10 part; The raw materials of this glaze also comprises the tinting material of 3-25 part.
The firing temperature of this glaze is 1210 ℃~1250 ℃; More specifically, the firing temperature of this glaze is 1230 ℃.
By the above-mentioned description of this invention as can be known, compared to the prior art, the present invention has following advantage: by adding other mineral raw material and industrial chemicals etc., changed the physical and chemical performance of base substrate, solved laterite product base glaze in conjunction with being difficult to and the frangible technical barrier of the uncommon pine of product quality; The firing temperature of glaze is down to 1230 ℃ by 1310 ℃, and firing temperature has reduced by 80 ℃, has reduced and has burnt till energy consumption, reduced the quantity discharged of firing rate and harmful body, both be conducive to environment protection, also saved a large amount of production costs, also improved class and the share of market of product; To traditional low temperature frit glaze formula reform, introduce novel material, replace plumbous oxide, develop unleaded furnace transmutation glaze, make it to be suitable for red soil greenwave body, fundamentally solve the ceramic decoration problem of environmental pollution.
