Mica-titanium pearlescent glaze for enamel painted porcelain, preparation method of glaze slip and application of mica-titanium pearlescent glaze

Abstract

The invention discloses a mica-titanium pearlescent glaze for enamel painted porcelain, a preparation method of glaze slip and an application of the mica-titanium pearlescent glaze. The mica-titaniumpearlescent glaze for the enamel painted porcelain comprises an enamel painted porcelain base glaze and a mica-titanium pearlescent pigment protective glaze in a weight ratio being 4:(1-8), wherein the enamel painted porcelain base glaze is prepared from components in percentage by weight as follows: 22%-40% of quartz, 12%-20% of lepidolite, 6%-10% of feldspar, 2%-3% of talc, 10%-23% of borax, 6%-11% of boric acid, 3%-9% of strontium carbonate, 1%-3% of zinc oxide, 0%-3% of zirconium silicate, 0.1%-3% of cerium oxide, 0.5%-3% of aluminium oxide and 0%-5% of fluorite, and the sum is 100%. High-temperature stability of mica-titanium pearlescent pigment can be improved, the pearlescent characteristic of a ceramic product can be guaranteed, various features of the traditional enamel painted porcelain can be kept, then the enamel painted porcelain product can display extremely beautiful interference effect (metal gloss and color), and the pearlescent effect is added to the enamel painted porcelain.

Description

technical field [0001] The invention relates to a mica titanium pearlescent glaze for enamel colored porcelain and a preparation method and application thereof, belonging to the technical field of ceramic materials. Background technique [0002] At present, with a long history, the enamel colored porcelain known as "the queen of colored porcelain" and "the official kiln in the official kiln" originated from France, the fashionable and romantic kingdom, and from the Rodin family, an artistic family. colored porcelain craft. It is a new technique of overglaze porcelain decoration influenced by copper body painting enamel imported from Europe. It is evolved from cloisonne. Cloisonne is made of enamel on copper body.

It is a new technique of overglaze porcelain decoration influenced by copper body painting enamel imported from Europe. It is evolved from cloisonne. Cloisonne is made of enamel on copper body. Enamel glaze is applied and then fired, so enamel colored porcelain is also called "painted enamel with porcelain body". However, it is difficult to produce pearlescent enamel colored porcelain crafts with current technology; mica titanium pearlescent pigments will lose their original luster due to the cracking and falling off of the cladding layer in high temperature environment. The surface structure of the medium mica will be destroyed, and the coating components such as titanium dioxide on the surface of the mica will also be sintered or chemically react with the glaze components to make it lose its pearlescent properties
