Problems solved by technology

Compared with the molten salt impregnation method, the high-temperature sintering method has the following disadvantages: the particle size of the surface slurry, the thickness and uniformity of the slurry are more stringent, the sample preparation process is cumbersome, and the effect of ion diffusion is affected by the operator's technique. The finished product has poor scratch resistance and wear resistance
However, pure use of silver salt for coloring in the mass production process will result in high processing costs and a relatively single color

Embodiment 1

[0016] Embodiment 1: This embodiment provides an ionic colorant and glass using the ionic colorant,

[0017] Original glass with thickness of 0.7mm, composition is SiO 2 65wt%, Al 2 O 3 13wt%, Na 2 O13wt%, K 2 O5wt%, MgO3wt%, B2O31wt%.

[0018] The glass was cleaned and placed in a preheating furnace at 250° C. for preheating for 10 minutes, and then placed in the molten ionic colorant composed of Table 1 for ion diffusion. After the ion diffusion is completed, the glass is taken out and placed in an annealing furnace at 260°C, cooled to room temperature, and taken out, and washed to obtain a light yellow finished product.

Embodiment 2

[0019] Embodiment 2: This embodiment provides an ionic colorant and glass using the ionic colorant,

[0020] Original glass with thickness of 0.7mm, composition is SiO 2 67wt%, Al 2 O 3 12wt%, Na 2 O12wt%, K 2 O5wt%, MgO3wt%, B2O31wt%. The glass was cleaned and placed in a preheating furnace at 260°C for preheating for 20 minutes, and then placed in the molten ionic colorant composed of Table 1 for ion diffusion. After the ion diffusion is completed, the glass is taken out and placed in an annealing furnace at 300°C, cooled to room temperature, taken out, and washed to obtain a reddish brown finished product.

Embodiment 3

[0021] Embodiment 3: This embodiment provides an ionic colorant and glass using the ionic colorant,

[0022] Original glass with thickness of 0.55mm, composition is SiO 2 66wt%, Al 2 O 3 15wt%, Na 2 O13wt%, K 2 O3wt%, MgO3wt%. The glass was cleaned and placed in a preheating furnace at 220°C for preheating for 10 minutes, and then placed in the molten ionic colorant composed of Table 1 for ion diffusion. After the ion diffusion is completed, the glass is taken out and placed in an annealing furnace at 300°C, cooled to room temperature, taken out, and washed to obtain a light yellow finished product.

Abstract

The invention provides an aluminum silicate glass ion coloring agent. The ion coloring agent is prepared from 20wt%-95wt% of a copper salt, 0.5wt%-5wt% of a silver salt and the balance a potassium salt. Specifically, copper ions in the copper salt are Cu<+>. According to the technical scheme, the silver salt and the copper salt are mixed to serve as the ion coloring agent, due to the existence ofCu<+>, Ag<+> can acquire electrons more easily to be reduced into colloidal Ag0 for color development, and color development can be achieved without an oxidation atmosphere or a reduction atmosphere.And on the premise of ensuring the coloring effect, the use amount of the Ag salt is reduced, and the raw material cost in the coloring process is reduced. Cu<2+>, Cu<+> and Cu<0> also have differentcolor developments and are combined with Ag<0>, so that a color mixing effect can be achieved.

Description

Technical field [0001] The invention relates to the field of glass manufacturing, in particular to an aluminum silicate glass ion colorant and a colored aluminum silicate glass using the ion colorant. Background technique [0002] With the continuous progress of science and technology and the continuous improvement of human living standards, the demand for various colored glass products is becoming more and more extensive, such as colored automotive glass, colored medical glass, colored architectural decoration curtain wall glass, etc. Human life. [0003] At present, the most widely used method for preparing colored glass is diffusion coloring on the glass surface, which is divided into three types: high temperature sintering method, steam method and molten salt immersion method. Compared with molten salt immersion method, high temperature sintering method has the following disadvantages: the requirements for the particle size, thickness and uniformity of the surface slurry are m...
