Embodiment 1

[0123] Embodiment 1: a kind of ceramic material:

[0124] This embodiment provides a ceramic material based on an organic ceramic precursor prepared by a method comprising the following steps:

[0125] S1 preparation of oligosilazane:

[0126] Under the protection of nitrogen, dissolve methylhydrogendichlorosilane in 10 times the volume of n-hexane, and react in an ice-water bath for 3 hours under the condition of passing a sufficient amount of ammonia gas. alkyl;

[0127] S2 prepares propargyl polysilazane:

[0128] Add pyridine and toluene to the oligosilazane, stir evenly and heat up to 60°C, add propyne bromide dropwise within 2 hours, keep warm and stir for 5 hours, and centrifuge the solution after natural cooling to obtain a yellow-brown transparent clear liquid, which is washed with toluene salt, and reclaim the washing liquid, and distill the centrifuged liquid under vacuum conditions to remove the solvent, to obtain final product;

[0129] S3 Preparation of sul...

Embodiment 2

[0176] Example 2: Another ceramic material:

[0177] This embodiment provides another organic ceramic precursor and a ceramic material based on it. The formula and preparation method of the organic ceramic precursor and a ceramic material based on it are basically the same as in Example 1, except that this embodiment In this paper, the organic ceramic precursor was directly replaced by oligomeric silazane instead of propargyl polysilazane, and ceramic materials were prepared based on it.

Embodiment 3

[0178] Example 3: Another ceramic material:

[0179]This embodiment provides another organic ceramic precursor and a ceramic material based on it. The formula and preparation method of the organic ceramic precursor and a ceramic material based on it are basically the same as in Example 1, except that this embodiment Among them, β-CD was used instead of SBE-β-CD without any modification to prepare organic ceramic precursors, and ceramic materials were prepared based on it.

Abstract

The present invention relates to the technical field of ceramics, and specifically provides an organic ceramic precursor and a ceramic material based on it. The organic ceramic precursor is a coexistence system of propargyl polysilazane and sulfobutyl ether-β-cyclodextrin , the organic ceramic precursor has stable properties and high ceramic conversion rate, adding three-dimensional sulfur and nitrogen doped graphene hydrogel to the aforementioned organic ceramic precursor, and after impregnation and calcination, a light and porous ceramic material can be obtained. It has excellent mechanical strength, electrical conductivity, heat insulation and sound effects. The present invention also provides a ceramic product with concave-convex texture, which specifically includes printing a glaze slurry containing polyborosilazane / alumina composite particles and gum arabic loaded with an antibacterial agent on the surface of the underglaze of the biscuit, and through other processes Finally, a ceramic product is obtained; the ceramic product has both certain mechanical strength and beautiful and diverse concave textures, and can also exert a durable and efficient antibacterial effect at the same time.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to an organic ceramic precursor and ceramic products. Background technique [0002] Ceramics is the collective name of pottery and porcelain, and it is also a kind of arts and crafts in our country. As far back as the Neolithic Age, our country has rough and simple painted pottery and black pottery. Pottery and porcelain have different textures and properties. Pottery is made of clay with high viscosity and strong plasticity as the main raw material. It is opaque, has fine pores and weak water absorption, and the sound of hitting is muddy. Porcelain is made of clay, feldspar and quartz, translucent, non-absorbent, anti-corrosion, hard and compact, and crisp when knocked. my country's traditional ceramic arts and crafts are famous all over the world for their high quality, beautiful shape and high artistic value.
