A kind of easy-to-clean daily-use porcelain and preparation method thereof

Abstract

The invention discloses an easy-to-clean daily procelain ware, which is formed by a procelain ware green body and an enamel layer arranged on the surface of the procelain ware green body. A blank for manufacturing the procelain ware green body is prepared from the raw materials in parts by weight: 45 to 47 parts of calcined talc, 28 to 30 parts of talc, 6 to 8 parts of feldspar, 10 to 12 parts of kaolin, and 5 to 7 parts of bentonite; a glaze material for forming the enamel layer is prepared from the raw materials in parts by weight: 88 to 90 parts of fusion cakes, 2 to 5 parts of kaolin, 6 to 8 parts of fine grinding kaolin, and 1 to 2 parts of bentonite. A preparation method comprises the steps of (1) preparing the blank; (2) preparing the glaze material; (3) forming a repair body; (4) bisque firing and spraying glaze; (5) sintering to obtain a finished product. The easy-to-clean daily procelain ware provided by the invention has better transmissivity, high strength, difficulty in cracking, and a remarkable easy-to-clean effect; according to the preparation method, the density and the strength of a product are improved, and the yield of the product is improved.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to an easy-to-clean daily-use porcelain and a preparation method thereof. Background technique [0002] Daily-use porcelain is porcelain used to contact food, such as plates, bowls, cups, saucers, pots, etc. Household china is designed to withstand repeated use, including cleaning. In the cleaning of conventional daily-use porcelain after use, some food residues with strong adhesion will often adhere to it, which is difficult to clean. In addition to using detergent, it must be wiped with a rougher special cloth to achieve the desired effect. Cleaning effect; this method of multiple wiping is easy to wear the glaze on the surface of the porcelain, making it easier to adhere to food, making it more difficult to clean. [0003] The main reason why the conventional daily-use porcelain is easy to stick to food and difficult to clean is that the density and hardness of the glaze layer...

Problems solved by technology

In the cleaning of conventional daily-use porcelain after use, some food residues with strong adhesion will often adhere to it, which is difficult to clean. In addition to using detergent, it must be wiped with a rougher special cloth to achieve the desired effect. Cleaning effect; this method of multiple wiping is easy to wear the glaze on the surface of the porcelain, making it easier to adhere to food, making it more difficult to clean

[0003] The main reason why ordinary daily-use porcelain is easy to stick to food and difficult to clean is that the density and hardness of the glaze layer are not good

The thickness ratio of the material (that is, the glaze) used in the glaze layer is not appropriate, especially the lack of ultra-fine materials (such as sub-micron materials), it is difficult to prepare a glaze layer with high density and low apparent porosity , this kind of surface seems to be a smooth glaze layer, which does not have an easy-to-clean effect when cleaning after use

[0004] In the daily-use ceramics production industry, engineers and technicians have improved the raw material formula and preparation process through conventional methods, but they have not really prepared a glaze layer with an easy-to-clean effect.
