Problems solved by technology

Although the thermal insulation effect of the former is obvious, but because most of these products are bonded products, and the strength of expanded perlite itself is small, the strength of this type of product is low and the water absorption rate is high
For ceramic products,

preparation example Construction

[0030] And, this embodiment also provides the preparation method of the above-mentioned lightweight thermal insulation honeycomb ceramics, including the following steps:

[0031] S1. Provide insulation layer materials and facing layer materials. The insulation layer materials include tuff mineral powder and pearls with a weight ratio of 25-50:40-90:10-30:10-30:1-15:5-15 Components of rock ore powder, expanded vitrified bead powder, glass powder, pore forming agent and sodium phosphate;

[0032] S2. Put the insulation layer material and the facing layer material into the mold for firing to form an integrated insulation layer and facing layer to obtain the light-weight heat-insulating honeycomb ceramics, or put the insulation layer material into the mold The heat-insulating layer is obtained by firing, and then the heat-insulating layer and the facing layer materials are combined through sintering or bonding to form the light-weight heat-insulating honeycomb ceramics.

Abstract

The invention provides a light heat-insulating honeycomb ceramic and a preparation method thereof. The light heat-insulating honeycomb ceramic comprises a heat insulating layer and a decoration layer combined with the heat insulating layer into a whole; and the heat insulating layer is prepared by sintering mineral powder of tuff, mineral powder of pearlite, expanded and vitrified microsphere powder, glass powder, a pore-forming agent and sodium phosphate. The light heat-insulating honeycomb ceramic has high strength and low water absorption, ensures that the decoration layer is firmly connected with the heat insulating layer, has a heat insulating function and also has an exterior wall decorating effect; and the preparation method has the advantages of simple process and low production cost.

Description

technical field [0001] The invention belongs to the field of ceramics, in particular to a light-weight thermal insulation honeycomb ceramic and a preparation method thereof. Background technique [0002] Porcelain and pottery have made great contributions in a wide range of human life, but one of their characteristic disadvantages is their specific weight. Generally speaking, the specific gravity of ceramics is 2.3-2.5. From the merits of the material properties, the weight is a big problem, and weight reduction is strongly desired. In addition, mainly in the field of building materials or artistic ceramic murals, it is hoped that if ceramics with beautiful glaze, free carving, free coloring, and good weather resistance and heat resistance can be lightened, then its use rate will increase further. [0003] So far, several measures have been taken to reduce the weight of ceramics. One is the method of forming bubbles by mixing foaming agent and firing, and the other is th...
