Leadless glaze medium stained paper flux and preparation method thereof

Abstract

The invention belongs to the technical field of ceramics, and particularly relates to leadless glaze medium stained paper flux and a preparation method thereof. The leadless glaze medium stained paperflux comprises the following raw materials according to a mass percentage: 10% of boric acid, 17% of borax, 30% of albite, 20% of quartz, 5% of lithium carbonate, 10% of calcite, and 8% of kaolin. The preparation method comprises the following steps: after uniformly mixing each material in proportion, firing by a tank furnace in 1500 DEG C, cooling to form a glass body, after that, levigating toabout 5 UM by using a ball grinder, after drying, and sieving totally by using 350 meshes of an airflow sieving machine. The provided leadless glaze medium stained paper flux and the preparation method thereof are capable of using leadless glaze medium pigment to replace lead-containing glaze medium pigment, in the precondition without affecting color development, guaranteeing brightness and immersing effect. The leadless glaze medium stained paper flux can pass a California test criterion of America, and is in comply with environment-friendly green requirements well.

Description

technical field

[0001] The invention belongs to the technical field of ceramics, and in particular relates to a lead-free glaze in-glaze paper flux and a preparation method thereof. Background technique

[0002] At present, decal paper is widely used in the glaze of tableware, and the roasting temperature is generally between 1000-1200°C, which varies with the glaze water temperature. For example, if the glaze water roasting temperature is around 1050°C, the glaze water contains lead and There are two kinds of lead-free, and the decorative in-glaze decals are basically lead-containing decals, so that they can ensure sufficient brightness and immersion, and the colors can be more vivid. However, it does not comply with the regulations of the relevant countries. Contents of the invention

[0003] In order to solve the problems in the above-mentioned technologies, the present invention provides a method for preparing a lead-free glaze decal flux.
