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 regenerated material and a preparation method thereof. The density of the first foamed ceramic layer is lower than that of the second foamed ceramic layer, and the densities of the first foamed ceramic layer and the second foamed ceramic layer are both lower than that of the porcelain stone interface layer. The present invention overcomes the defect that the single-density material produced in the prior art has excellent single function, relatively lacks other functions, and cannot simultaneously meet the requirements for external protection of building wall materials. The overall performance is significantly improved, and all indicators are better than the current development The foam ceramic material can meet the requirements of thermal insulation and energy saving, waterproof and moisture-proof, fire-resistant and burn-resistant, safe and not falling off, sound insulation and noise reduction, durable and strong.

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 produced lightweight foamed ceramic partition board and thermal insulation board have the functions of light weight, heat preservation, compression resistance, folding resistance, fire prevention, waterproofing, sound insulation, etc., and have the effects of environmental protection and energy saving, and 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 and the requirements of the application scenario do not match frequently occur. [0003] Due to the close correlation between the brittleness and density of foamed ceramics and th...
