Embodiment

[0044] A method for preparing lead-free and easy-to-clean household porcelain, comprising the steps of:

[0045] 1) Preparation of blank;

[0046] Use commercially available feldspar porcelain raw materials, or according to the existing technical formula, for example: clay, quartz, feldspar in the ratio of 2:1:1 to prepare green body raw materials, the chemical composition of the material is calculated as: SiO 2 65-75%, Al 2 o 3 20-28%, K 2 O+Na 2 O is not less than 2.5%, and the others are unavoidable impurities.

[0047] 2) Preparation of glaze: make glaze according to prior art, wherein, the average fineness of glaze is 200-400 mesh

[0048] Glaze formula: feldspar 20-40, coke gem 10-20, cooked talc 10-20, Datong soil 5-10, stalactite 1-2, quartz 1-3, barium titanate 1-2, bismuth oxide 1-2 , lanthanum oxide 0.1-0.5, improver 0.1-0.5, 0.1-0.5 parts of colorant; the improver is a mixture of yttrium oxide, cerium oxide and samarium oxide in a weight ratio of 1:1:1; in o...

Abstract

Lead-free easily-cleaned porcelain for daily use and a preparation method thereof belong to the technical field of porcelain for daily use. The lead-free easily-cleaned porcelain for daily use comprises a green body and glaze which covers the green body, and is characterized in that the glaze is fritted glaze prepared from the following raw materials (by weight): 20-40 parts of feldspar, 10-20 parts of flint clay, 10-20 parts of calcined talcum, 5-10 parts of Datong kaolin, 1-2 parts of stalactite, 1-3 parts of quartz, 1-2 parts of barium titanate, 1-2 parts of bismuth oxide, 0.1-0.5 part of gloss agent and 0.1-0.5 part of an improver. The gloss agent is lanthana. The improver is a mixture of yttrium oxide, cerium oxide and samaria according to the weight ratio of 1:1:1; or the improver is a mixture of cerium oxide, samaria and gadolinium according to the weight ratio of 1:1:1. The green body is feldspathic porcelain or steatite porcelain. By the adoption of the lead-free ceramic glaze and by optimizing the preparation technology, the surface-smooth porcelain for daily use is obtained. The porcelain for daily use has excellent anti-fouling performance and easy cleaning performance, and heavy metal content such as content of lead and cadmium, etc. is one-tenth of the national standard.

Description

technical field [0001] The invention relates to the technical field of daily-use porcelain, in particular to a lead-free easy-to-clean daily-use porcelain and a preparation method thereof. Background technique [0002] Daily-use ceramics are frequently used in people's daily life, especially in the process of people's catering. The basic form of daily-use porcelain is: a ceramic body, the outer surface of which is covered with a glaze. [0003] Heavy metals such as lead and cadmium in the glaze are easy to exceed the standard, which is harmful to human health. As people pay more and more attention to health, people pay more and more attention to the amount of lead and cadmium dissolved in ceramic glaze. The Zn content of the lead-free ceramic glaze of the prior art is too high, and it contains Bi 2 o 3 , the substance has certain toxicity and high price. [0004] In addition, daily-use porcelain is difficult to clean as a daily utensil. In the catering industry, cleanin...
