Technical Field

The invention belongs to the field of ceramics, and particularly relates to a preparation method of a rainforest blue glaze daily ceramic.

Background

The glaze is named as rainforest blue glaze because white fine lines are densely distributed in the dark blue background color, and the glaze falls down like rain and has the wind of tropical rainforests. Under the new energy-saving and environment-friendly trend of the current daily ceramic enterprises, the roller kiln which takes natural gas as clean energy is generally adopted to burn ceramic products, and the firing period of the roller kiln is very short, so that the method is a restriction factor for firing the kiln change glaze ceramic products which need longer firing time.

Disclosure of Invention

The purpose of the invention is as follows: the invention aims to overcome the defects in the prior art, and provides a preparation method of a rainforest blue glaze ceramic container which can adapt to roller kilns for about 5 hours conventionally and is simple and convenient to implement firing control.

The technical scheme is as follows: in order to solve the technical problems, the invention discloses a novel preparation method of a kiln transformation rainforest blue glaze ceramic container, which comprises the following steps,

(1) preparing a blank: and (3) blank material: ball: water is mixed according to the mass ratio of 1: 1: 0.4-0.5, ball milling for 3.5-5 hours, stirring, sieving, absorbing iron, storing, aging, and slip casting;

(2) biscuit firing: the firing temperature is 960 ℃, and the firing time is 5 hours;

(3) preparing a base glaze and a cover glaze: respectively carrying out base glaze and surface glaze preparation: ball: water is mixed according to the mass ratio of 1: 1.5: 1.1-1.2, ball milling for 24 hours, and adjusting the concentration to 30 baume degree of ground glaze and 42 baume degree of surface glaze when the fineness of glaze slip reaches 250 meshes and the screen residue is 0.4-0.6%;

(4) glazing: applying base glaze by using a glaze dipping method, and applying overglaze by using a glaze dipping method or a glaze spraying method, wherein the total thickness of a glaze layer is controlled to be 1-2 mm;

(5) glaze firing: after drying, the mixture enters a roller kiln, the firing temperature is 1180-1190 ℃, the firing period is 5 hours, and the mixture is fired and discharged from the kiln;

(6) and (4) checking: and (5) checking whether the outer glaze surface has the defects of pinhole glaze shrinkage, glaze bubbles and the like.

Preferably, in step (3), the ground coat: the soil comprises, by weight, 32-40 parts of feldspar, 26-32 parts of quartz, 5-10 parts of calcite, 3-6 parts of Suzhou soil, 8-12 parts of manganese dioxide, 10-13 parts of Yixing clay and 1-3 parts of Yixing soil bones.

Preferably, in step (3), the overglaze: the material comprises, by weight, 34-42 parts of Jiangzhou potassium feldspar, 4-7 parts of Huzhou quartz, 8-12 parts of Changxing calcite, 6-9 parts of Suzhou kaolin, 8-12 parts of glass powder, 5-7 parts of industrial pure zinc oxide, 2-4 parts of industrial pure barium carbonate, 3-6 parts of industrial pure strontium carbonate, 6-9 parts of ferric oxide, 3-5 parts of industrial pure copper oxide and 2-4 parts of cobalt blue pigment.

Preferably, in the step (3), when the fineness of the glaze slip reaches 250 meshes, the screen residue is 0.5%.

Preferably, in step (5), the firing temperature is 1185 ℃.

Preferably, in step (5), the treatment of the cooling and incubation stage is not separately performed.

Has the advantages that: compared with the prior art, the invention has the following remarkable advantages: the invention adopts a secondary glazing method, namely, a biscuit which is biscuit-fired is glazed by a glaze dipping method firstly, and then is glazed by a glaze dipping or glaze spraying method, because two glaze raw materials of argil and soil bone which are suitable for local traditional special products are adopted in the blue glaze, the argil and the soil bone are low in cost and rich in iron components, the argil and the soil bone have the functions of color development in the glaze and help the glaze to promote ferric oxide microcrystallines to be fully separated out in the cooling process, meanwhile, zinc oxide and ferric oxide are used as seeding agents in the glaze, and most importantly, two fluxes of barium carbonate and strontium carbonate are added, because the introduction of the combined flux can effectively ensure that zinc oxide and ferric oxide with good crystallization capacity are in a supersaturated state in the glaze after the reaction between the glaze and the glaze in the high-temperature calcination process, the method can adapt to the cooling time of a roller kiln fast period, crystal nucleus precipitation and growth and development in the glaze body melt are fully completed, and the expected effect of forming a beautiful and elegant rainforest blue glaze surface is achieved; by reasonably selecting the components of the ground glaze and the surface glaze and accurately controlling the proportion, the independent treatment of a cooling and heat-insulating stage is not needed in the container sintering process, and the glaze effect with more stable micro-crystallization of the rain forest blue glaze can be obtained. The lead and cadmium release amounts of the ceramic product decorated by the rainforest blue glaze are respectively less than 0.5mg/L and 0.25mg/L, and the ceramic product conforms to the national standard regulation and ensures the health of users.
