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 invention relates to the technical field of ceramics and specifically provides an organic ceramic precursor and a ceramic material based on the organic ceramic precursor. According to the organicceramic precursor, propargyl polysilazane and sulfobutyl ether-beta-cyclodextrin coexist in a system; wherein the organic ceramic precursor is stable in property and high in ceramic conversion rate, the three-dimensional sulfur-nitrogen doped graphene hydrogel is added into the organic ceramic precursor, and the light and porous ceramic material is obtained through dipping and calcining. The ceramic material has excellent mechanical strength, conductivity, heat insulation effect and sound insulation effect. The invention also provides a ceramic product with concave-convex textures, which is prepared through the following steps: printing glaze slip containing polyborosilazane / aluminum oxide composite particles and an Arabic gum loaded antibacterial agent on the surface of the ground coat ofa biscuit, and finally obtaining the ceramic product through other processes. The ceramic product has certain mechanical strength and attractive and diverse concave textures, and can also play a lasting and efficient antibacterial role 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.
