Pearlescent embossed pigment on ceramic glaze, pearlescent embossed paper on ceramic glaze and production method

Abstract

The invention relates to a ceramic overglazed pearlescent relief pigment, a ceramic overglazed pearlescent relief color decal paper and a manufacturing method thereof and belongs to the technical field of ceramic overglazed color printing. The ceramic overglazed pearlescent relief pigment comprises the following components in percentage by mass: 30-40% of feldspar, 15-25% of borax, 5-15% of kaoline and 20-50% of low-temperature lead-free frits, wherein the percentage sum of all the components is 100%. After a ceramic product is decaled by using the ceramic overglazed pearlescent relief color decal paper prepared by the manufacturing method, an overglazed pearlescent relief has a relatively strong adhesive force and favorable glossiness, the ceramic product is enabled to have excellent stain resistance, scrubbing resistance and wear resistance and is also enabled to have an excellent metal pearlescent colorating effect, and the ceramic product can show pearlescent metal effects with different degrees under rays with different angles; in addition, the manufactured decal paper is attractive in appearance, environment-friendly and extremely low in lead and cadmium dissolution quantity and conforms to the standards of China and each of Europe and America.

Description

technical field [0001] The invention belongs to the technical field of ceramic overglaze color printing, and in particular relates to a ceramic overglaze pearlescent embossed pigment, ceramic overglaze pearlescent embossed colored flower paper and a production method. Background technique [0002] Ceramic pearlescent embossed pigments are embossed overcoat pigments specially used for ceramic glaze decals. It is characterized in that it can achieve a strong metallic feeling after production and firing, and can display different metallic effects under different angles of light. Its color The transformation is rich, basically close to the hair color of organic pigments. The traditional pearlescent relief pigment is mainly composed of artificially synthesized titanium oxide mica flakes, and its firing melting point is about 1500°C. Although the cost of titanium oxide mica flakes is low, it has the following disadvantages: first, poor adhesion; second , the surface is rough and ...

Problems solved by technology

The traditional pearlescent relief pigment is mainly composed of artificially synthesized titanium oxide mica flakes, and its firing melting point is about 1500°C. Although the cost of titanium oxide mica flakes is low, it has the following disadvantages: first, poor adhesion; second , the surface is rough and glossy; third, the stain resistance is poor and not resistant to washing; the current solution is to print a transparent cover layer on the printed pearlescent pattern, so as to improve the gloss and abrasion resistance of the surface of ceramic products , but due to the poor match between pearlescent pigment and transparent cover layer, it brings new problems: the surface of ceramic products not only loses the metallic feeling that pearlescent pigment should have, but also affects the color of pearlescent pigment itself

[0003] And although there are many reports of relief on the relevant ceramic glaze in the prior art, there is no report of pearlescent relief, and the current relief paper has only single colors such as transparency and milky white, and the limitations are relatively large, and the above-mentioned many deficiencies are mainly It is caused by the limitation of relief pigment formula and production process, and the relief pigment of many flower papers will be unevenly distributed after being pasted on ceramic products and dried, which will affect the appearance of ceramic products, because the relief on the glaze has a great influence on the relief pigment. The composition and production process requirements are higher than those of pigments in glaze

The Chinese patent application No. 201410243698.X submitted by the applicant in 2014 discloses a manufacturing process of overglaze pastel relief printed products. Although it fills the gap in the color system of overglaze relief, the applicant is In the follow-up research, it was found that the pastel relief color effect of this decal paper is not obvious in the actual use process, the firing temperature is relatively high, and its color matching is also cumbersome, which still needs further improvement
