Problems solved by technology

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a flux for ancient color pigments. By adjusting the formula of flux raw materials and controlling the ratio of flux raw materials, a series of ceramics such as easy cracking, peeling, and flow of existing ceramic ancient color pigments are solved. Recognized defects in the field of decoration, while achieving lead-free, cadmium-free and pollution-free, it maintains the unique glass texture of ancient colors, and does not have the inherent defects of traditional alkali borosilicate (ABS) systems, and obtains bright and pure ceramic ancient color decorations Effect, the present invention has practical significance to promoting the inheritance and development of ceramic decorative arts

Embodiment 1

[0042] The ancient color pigment is prepared according to the following chemical composition and preparation method.

[0043] SiO 2 25wt%, B 2 o 3 40wt%, modified nano ZnO 20wt%, Na 2 O is 3wt%, Li 2 O is 3wt%, K 2 O is 2 wt%, BaO is 2 wt%, and MgO is 5 wt%.

[0044] Wherein, the preparation method of modified nanometer ZnO is:

[0045] (1) S1: Take nano-zinc oxide (60nm), add water to prepare a nano-zinc oxide suspension with a concentration of 4.5%, adjust the pH value of the suspension to 5.5 with ammonia water under stirring conditions, heat to 80°C, and stir for 40 minutes , filtered, and the resulting solid was dried at 100° C. for 3 hours to obtain activated nano-zinc oxide;

[0046] (2) S2: take the activated nano-zinc oxide, and Bi(NO 3 ) 3 ·5H 2 O solution mixed, wherein the activated nano ZnO and Bi(NO 3 ) 3 ·5H 2 The mass volume ratio of the O solution is 1:25g / ml, stirred for 40min, and then reacted in an autoclave at 150°C for 3h. 2 o 3 Modified na...

Embodiment 2

[0049] The ancient color pigment is prepared according to the following chemical composition and preparation method.

[0050] SiO 2 20wt%, B 2 o 3 35wt%, modified nano ZnO 16wt%, Na 2 O is 8wt%, Li 2 O is 8wt%, K 2 O is 5 wt%, BaO is 5 wt%, and MgO is 3 wt%.

[0051] Prepare modified nano-ZnO according to the method described in Example 1, mix the raw materials evenly, pass through an 80-mesh sieve, melt at a heating rate of 8°C / min to 1280°C, keep at the highest temperature for 45min, water quench, dry, and finely grind until the powder can All pass through a 350-mesh sieve to obtain a flux, add ancient color coloring agent (copper oxide) according to the weight ratio of 1:0.15, mix and grind for 15 minutes to obtain a pigment, add 40wt% clear water and grind for 10 minutes when using, for ancient Coloring.

Embodiment 3

[0053] The ancient color pigment is prepared according to the following chemical composition and preparation method.

[0054] SiO 2 30wt%, B 2 o 3 29wt%, modified nano ZnO 20wt%, Na 2 O is 5wt%, Li 2 O is 4wt%, K 2 O is 4 wt%, BaO is 4 wt%, and MgO is 4 wt%.

[0055] The modified nano-ZnO was prepared according to the method described in Example 1, the flux was prepared according to the method described in Example 2, and the ancient color colorant (Guangcui) was added according to the weight ratio of 1:0.40, mixed and milled for 15 minutes to obtain a pigment. When using, add 40wt% clear water and grind for 10 minutes for ancient color filling.

Abstract

The invention discloses a flux for ancient color pigments and an application method thereof, using natural mineral raw materials and chemical raw materials, according to the percentage of chemical composition: SiO 2 20~30wt%, B 2 o 3 25~40wt%, modified nano ZnO 16~20wt%, Na 2 O is 3~8wt%, Li 2 O is 3~8wt%, K 2 O is 2-5wt%, BaO is 2-5wt%, and MgO is 3-7wt%. After batching, mixing, melting, quenching, and fine grinding, the flux for ancient color pigments is obtained, wherein the modified nano-ZnO is Bi 2 o 3 Modified nano-ZnO, the invention adjusts the flux raw material formula and controls the flux raw material ratio to solve a series of recognized defects in the field of ceramic decoration such as easy cracking, peeling, and flow of existing ceramic ancient color pigments, and finally obtain bright and pure color ceramics The effect of ancient color decoration on glaze has practical significance for promoting the inheritance and development of traditional ancient color ceramic decoration.

Description

technical field [0001] The invention relates to the field of traditional ceramic decoration materials, in particular to a flux for ancient color pigments and an application method thereof. Background technique [0002] As one of the list of intangible cultural heritage, ancient color, also known as "five colors", "Kangxi five colors" and "hard color", is an excellent painted decoration with a long history and unique national culture. pivotal position. Ancient colored ceramics have always been famous all over the world, loved and appreciated by people, and have been collected and praised by collectors and connoisseurs at home and abroad over the years. Ancient colors are mainly composed of five glassy colored materials including red, yellow, green, blue and purple (emerald), which are painted on ceramics according to patterns and patterns by means of overglaze coloring techniques. After the ancient color pigment is fired, it forms a glass texture, which is transparent and g...
