Foamed ceramic insulation board and preparation method thereof

Abstract

The invention discloses a foamed ceramic insulation board and a preparation method thereof. The foamed ceramic insulation board comprises a foamed ceramic base board which is composed of the following materials in parts by weight: 40-75 parts of ceramic brick polishing slag, 10-40 parts of feldspar, 3-6 parts of calcined talc, 4-10 parts of red clay, 0-2 parts of fluorite, 1-2 parts of lithium feldspar, 1-3 parts of carborundum and 2-4.5 parts of stabilizers. The materials are subjected to the processes of homogenizing, ball milling, drying, setting, sintering and cutting to form the foamed ceramic base board. The foamed ceramic insulation board has a low heat conduction coefficient, is non-combustible and non-permeable, has a property of shielding and blocking vapor and liquid, has the properties of fire prevention, water prevention, acid-base resistance, weathering resistance and the like, has the characteristics of high strength and the like, thereby being an ideal heat-preservation and heat-insulating material.

Description

technical field [0001] The invention relates to the field of wall insulation materials, in particular to a foamed ceramic insulation board and a preparation method thereof. Background technique [0002] With the progress of society, people's concept of environmental protection has gradually deepened. Wall insulation material is a new type of wall insulation material developed in recent years. Its function is to save materials, improve wall insulation performance, save resources, and reduce environmental pollution. Ceramic foam insulation material is a new type of material developed in recent years. It has the advantages of high porosity, low thermal conductivity, light weight, high hardness, thermal shock resistance, high temperature resistance, corrosion resistance and good mechanical strength.

AI Technical Summary

Problems solved by technology

[0003] The current foamed ceramic insulation board is a high-porosity closed-cell ceramic material made of clay ore as the main raw material, which is baked at high temperature by advanced production technology and foaming technology; the product is suitable for building exterior wall insulation, fire protection isolation belt , building self-insulation cold and heat bridge treatment, etc., overcome the fatal weakness of organic materials that are not fireproof and easy to age; There are defects in performance, which will affect its service life, and it will affect the appearance of the building after it is used on the building.

[0004] Ceramic bricks are commonly used materials in construction, and a large amount of waste residue will be generated during the production process. If these waste residues are discharged into the environment without treatment, it will not only cause environmental pressure, but also cause environmental pollution. There is no good solution yet way
