Problems solved by technology

Further use results show that although pure ultra-fine silica can improve the color hair effect to a certain extent, there are still certain limitations, including the limited effect of hair color aid, and the effect of hair color aid is due to the effect of metal oxides. There is a big change depending on the type, and the hair coloring effect on some colors is extremely limited

preparation example Construction

[0032] As a further improvement of the above-mentioned silicon dioxide material with a color-aiding effect, its preparation method includes the following steps:

[0033] 1) Wash away the impurity salt on the surface of the silica substrate as required;

[0034] 2) adjusting the pH of the silica matrix to be 6-8, preferably 6.5-7.5;

[0035] 3) adding a color-assisting salt with a color-aiding effect to the silica matrix, the color-assisting salt is selected from at least one of water-soluble metal salts and boron-containing salts, and fully stirred evenly;

[0036] 4) filtering, drying and crushing to obtain silica material.

[0037] Due to the preparation process of the silica matrix, it is inevitable that some impurity salts will be contaminated. In order to avoid the reaction of impurity salts and color-assisting salts and affect the final color-aiding effect of the material, it is necessary to purify the silica matrix to avoid this phenomenon. If the silica matrix used ...

Embodiment 1

[0045] An ultra-fine silica material with significant hair coloring effect, the matrix is ​​composed of fumed silica slurry, the primary particle size of silica in the matrix is ​​7nm, and the specific surface area is 380m 2 / g, the stacked pore diameter is 5-20nm. The acid-base regulator is a sulfuric acid solution, the potassium chloride solution is selected as the color-promoting ion solution, the addition amount is 2.0%, and the particle size of the jet mill is 15 μm. When applied, it accounts for 3% by mass in the surface glaze of the ceramic tile or the dry basis of the fabric.

[0046] The preparation method is as follows: (1) adjusting the pH value of the ultrafine silica matrix to about 7 with an acid-base regulator; (2) adding a color-promoting ion solution to the neutral ultrafine silica matrix in proportion, Stir well; (3) filter and dry; (4) jet mill and crush.

[0047]The method of use is: add the ultra-fine silica material with a significant color-promoting ef...

Embodiment 2

[0049] An ultra-fine silica material with significant hair coloring effect, the matrix is ​​composed of silica airgel slurry, the primary particle size of silica in the matrix is ​​5nm, and the specific surface area is 600m 2 / g, the stacked pore diameter is 10-20nm. The acid-base regulator is ammonia solution, and potassium chloride and magnesium chloride solutions are selected as the color-promoting ion solution, the addition amount is 2.0%, and the particle size of the jet mill is 20 μm. When applied, its mass proportion in the glaze of the ceramic tile or the dry basis of the fabric is 2%.

[0050] The preparation method and usage method are the same as in Example 1.

Abstract

The invention discloses an ultrafine silica material having a significant color development assisting effect, and an application thereof. A color development assisting salt is deposited on the surfaceof a silica material. The ultrafine silica material can effectively coat color development metal oxide in order to guarantee that the metal oxide stably show the color at a high temperature. The ultrafine silica material has an excellent color development assisting effect on metal oxides having multiple colors, and has a better color development assisting effect than simple ultrafine silica.

Description

technical field [0001] The invention relates to a ceramic ink-jet printing additive and its application, in particular to an ultra-fine silicon dioxide material which significantly promotes color development and its application. Background technique [0002] Polished tiles were born in the late 1980s. They are loved by consumers because of their excellent properties such as high hardness, high brightness, wear resistance, good texture, and small color difference. They are mainstream products in the domestic market. played an important role in the development of the industry. [0003] In recent years, a variety of decorative technologies have greatly improved the decorative effect of ceramic tiles, especially the comprehensive promotion and application of inkjet printing technology, which is known as the third decoration technology revolution in the ceramic industry, has made ceramic tile products more colorful and realistic. , personalization and unlimited creativity.
