Process for producing foam ceramic heat-insulation boards

Abstract

The invention discloses a process for producing foam ceramic heat-insulation boards. The process includes preparing raw materials, mixing and grinding prepared fusible clay, kalialbite and boron nitride to obtain powder, stirring the powder, then adding foaming agents and organic solvents into the powder to obtain uniformly mixed primary slurry and heating the primary slurry to allow the primary slurry to be in molten states; pouring materials into molds and quickly cooling the materials until the temperatures of the materials reach the normal temperature; cooling the materials in the molds, then releasing the materials from the molds to obtain heat-insulation board blanks, polishing the surfaces of heat-insulation boards by three times and separately smearing ground glaze, basic glaze andcolored glaze on the heat-insulation boards whenever the heat-insulation boards are polished. The process has the advantages that good heat-insulation effects can be realized, the deformation coefficients of products can be lowered, and the products are extremely low in deformation rate even in high-temperature environments; the weights of materials can be reduced, accordingly, the materials arelight and are good in toughness, and the service lives of the materials can be greatly prolonged.

Description

technical field [0001] The invention relates to a ceramic thermal insulation material, in particular to a production process of a foamed ceramic thermal insulation board, which belongs to the technical field of building materials. Background technique [0002] With the sustained and rapid development of my country's economy, the problems of energy and resources have become increasingly prominent. Environmental protection, energy conservation and emission reduction, rational use of resources, and the development of low-carbon circular economy have become new development directions. Among them, the wall insulation material is a new type of environmentally friendly material developed in recent years. It can save materials, improve the insulation performance of the wall, and reduce environmental pollution. There are many types of wall insulation materials at present, among which foamed ceramic insulation boards are widely used. It uses clay tailings, ceramic fragments, river sil...
