preparation example Construction

[0072] Such as figure 1 As shown, one embodiment of the present invention provides a method for preparing foamed ceramics with a relief effect, comprising the following steps:

[0073] S10, weighing the green body raw material of the foaming matrix layer, ball milling and granulating to obtain a first powder, then pressing the first powder into a first green body, and scraping the first green body;

[0074] S20. Weigh the green body raw material of the relief effect layer, and obtain the second powder after ball milling and granulation, and then lay the second powder on the scraped first green body; use a relief mold , pressing the second powder laid on the first green body into a second green body, and forming a relief structure on the second green body;

[0075] S30. Transferring to a kiln for one-time high-temperature sintering, the first green body and the second green body are sintered to form one body, and then cut and processed into required sizes to obtain foamed cera...

Embodiment 1

[0093] A method for preparing foamed ceramics with a relief effect, comprising the following steps:

[0094] Weigh the green body raw material of the foaming matrix layer, and its mass percentage is: tailings 66.5%, talc 20%, calcium oxide 2%, kaolin 10%, dispersant 1.0%, foaming agent 0.5%; The raw materials are transferred to a ball mill for ball milling to obtain a slurry, and then the slurry is sprayed and granulated to obtain a green body powder of the foamed matrix layer, and then the green body powder of the foamed matrix layer is pressed to form a foamed matrix layer blank body, and scrape the upper surface of the foamed matrix layer green body;

[0095] Weigh the green body raw material of the embossed effect layer, and its mass percentage content is: tailings 66.5%, talc 20%, calcium oxide 2%, kaolin 10%, dispersant 1.0%, foaming agent 0.3%; Transfer to a ball mill for ball milling to obtain a slurry, and then spray and granulate the slurry to obtain the green body ...

Abstract

The invention provides a foamed ceramic with an embossment effect. The foamed ceramic comprises a foaming base body layer and an embossment effect layer which are sequentially arranged, the foaming base body layer and the embossment effect layer are formed into a whole through one-time sintering, the volume density of the foaming base body layer is 0.36-0.5 g / cm < 3 >, and the volume density of the embossment effect layer is 0.5-1.0 g / cm < 3 >. The foamed ceramic with the embossment effect is formed through one-time sintering, the surface of the foamed ceramic directly has the embossment effect of an embossment structure, and further carving and surface decoration are not needed. The invention further provides a preparation method of the foamed ceramic with the embossment effect.

Description

technical field [0001] The invention relates to the technical field of building decoration materials, in particular to a foamed ceramic with a relief effect and a preparation method thereof. Background technique [0002] Foamed ceramic (foamed ceramic) material is a porous material with high temperature characteristics. It has excellent properties such as low thermal conductivity, light weight, high hardness, corrosion resistance, wear resistance, water seepage resistance and easy regeneration. It can be widely used in Environmental protection, industrial and civil construction, national defense industry, petrochemical industry, municipal construction, underground engineering, road traffic, bridges and tunnels, biological planting, refrigeration industry and thermal equipment and many other fields. Relief is a semi-three-dimensional sculpture art form, which forms a three-dimensional shape by embossing on the surface of the material. By decorating the foamed ceramic plate a...
