AI Technical Summary

Problems solved by technology

The high-temperature bright red inkjet ink must use finer bright red color based on the suspension of the color material, resulting in further deterioration of the high temperature resistance of the bright red material with inherently poor high-temperature performance, and the red brilliance that appears at high temperatures is difficult to meet the requirements

preparation example Construction

[0052] The preparation method of the red glaze rock plate comprises the following steps:

[0053] Step 1: pressing the green body powder to obtain a green body, and drying the green body;

[0054] Step 2. apply a large red surface glaze on the surface of the dried body; the chemical composition of the basic glaze of the large red surface glaze includes: by mass percentage, SiO 2 : 64.15%, Al 2 o 3 : 19.78%, Fe 2 o 3 : 0.22%, TiO 2 : 0.15%, CaO: 0.28%, MgO: 0.11%, K 2 O: 3.88%, Na 2 O: 3.15%, ZrO 2 : 6.45%, loss on ignition: 1.80%; the big red surface glaze adopts the method of spraying glaze, and the specific gravity is 1.45g / cm 3 , the glaze amount is 500g / m 2 ;

[0055] Step 3. apply red soft glaze on the body surface after applying the red top glaze; the chemical composition of the basic glaze of the red soft glaze includes: by mass percentage, SiO 2 : 55.46%, Al 2 o 3 : 15.88%, Fe 2 o 3 : 0.14%, TiO 2 : 0.15%, CaO: 5.5%, MgO: 3.89%, BaO: 3.93%, K 2 O: 5.14...

Abstract

The invention discloses a bright red glaze rock plate and a preparation method thereof. The preparation method comprises the following steps: applying bright red cover glaze on the surface of a green body; applying bright red soft light glaze on the surface of the green body after the bright red cover glaze is applied; applying bright red water glaze on the surface of the green body applied with the bright red soft light glaze; and drying and sintering the green body applied with the bright red water glaze to obtain the bright red glaze rock plate. According to the preparation method, the bright red degree value of the bright red cover glaze of the rock plate is close to saturation and the color is uniform through three glazing procedures with complementary effects, namely the bright red cover glaze, the scarlet soft light glaze and the bright red water glaze.

Description

technical field [0001] The invention relates to a red-glazed rock plate and a preparation method thereof, and belongs to the technical field of ceramic plate production and manufacture. Background technique [0002] Big red glaze is very popular among Chinese people because of its bright red color. However, the poor high temperature resistance and easy decomposition of the scarlet material limit its application in architectural ceramics, especially rock slabs. Chinese patent CN 104860720A discloses a high-temperature bright red inkjet ink for ceramic decoration, which is prepared according to the following components by weight: 15-25 parts of basic glaze powder, 15-25 parts of bright red material, 50-70 parts of solvent; Prepared according to the following components by weight: 86-90 parts of frit, 2-4 parts of kaolin, 4-6 parts of titanium dioxide, 4-6 parts of cerium oxide, 0.02-0.04 parts of carboxymethyl cellulose, sodium tripolyphosphate 0.2-0.4 parts, 37-40 parts of ...
