Problems solved by technology

The surface of the product has low wear resistance, is easy to scratch, and is easy to fall off ash
When used as a building material, it is difficult to install and there are potential safety hazards
[0004] In summary, the advantages of foamed ceramics with a single density and structure are not prominent in practical applications, their weaknesses are magnified, and their strengths are covered up, which leads to the development of the entire industry encountering bottlenecks when entering the application field. Therefore, it is necessary to develop a multifunctional Multi-structure foamed ceramic products overcome the above defects and eradicate potential safety hazards to meet market needs

Abstract

The invention discloses a three-layer double-density foamed ceramic recycled material and a preparation method thereof. The three-layer double-density foamed ceramic recycled material comprises a first foamed ceramic layer, a chinastone interface layer and a second foamed ceramic layer which are sequentially stacked and fired at the same time. The density of the first foamed ceramic layer is smaller than that of the second foamed ceramic layer. The density of the first foamed ceramic layer and the density of the second foamed ceramic layer are smaller than the density of the chinastone interface layer. The defects that a single-density material produced in the prior art is excellent in single function but poor in other functions and incapable of meeting the outer envelope requirement of abuilding wall material at the same time are overcome, the overall performance is obviously improved, various indexes are superior to those of an existing foamed ceramic material, the requirements forheat preservation and energy conservation are met at the same time, the material is water-resistant, damp-resistant, fire-resistant, burning-resistant, safe and does not fall off, sound insulation andnoise reduction are achieved, and the material is durable and firm.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a three-layer double-density foamed ceramic regenerated material and a preparation method thereof. Background technique [0002] The lightweight foamed ceramic partition boards and insulation boards produced have the functions of light weight, heat preservation, compression resistance, flexural resistance, fire prevention, waterproof, sound insulation, etc., and have environmental protection and energy saving effects. They can be used as building wall materials or It is used for exterior wall decoration to achieve the goal of building weight reduction and energy saving. However, in the actual application process, the situation that the characteristics of the product do not match the requirements of the application scenario occurs from time to time. [0003] Due to the brittleness of foamed ceramics and the close correlation between density and thermal insu...
