Abstract

The invention provides a graphene-based foamed ceramic insulation wallboard, which is made of the following components: potassium sodium feldspar, ceramic waste residue, graphene, vermiculite, high-temperature co-solvent, expanded graphite, zirconia, clay, stable agent and debonding agent. Using potassium sodium feldspar and ceramic waste slag as the base material, adding graphene and vermiculite to make the board more lightweight, high-strength, thermal insulation, and improve the performance of the board such as fire resistance, insulation and weather resistance, using expanded graphite as a foaming agent, using high temperature The foaming process can better control the density, pore distribution and pore size of the board, achieve better heat preservation and light weight effects, and make a board with remarkable anti-aging, corrosion resistance, heat insulation, sound insulation, waterproof and impervious, fireproof and fireproof. , lightweight, high-strength, non-cracking, green and environmental protection and other comprehensive performance in one foam lightweight wallboard.

Description

technical field [0001] The invention relates to the technical field of new building materials, in particular to a graphene-based foamed ceramic thermal insulation wallboard and a preparation method thereof. Background technique [0002] With the development of society, people's demand for energy continues to increase. On the one hand, people are devoting themselves to the development of new energy sources, and on the other hand, people are adopting energy-saving measures and using energy-saving materials to achieve energy saving. In recent years. People have been devoting themselves to the development of thermal insulation materials. When traditional concrete aerated blocks, shale hollow bricks, and ceramsite concrete wall panels are applied to the interior and exterior walls of buildings, they are large in size, occupy a lot of building space, are heavy in weight, and require sporadic wet masonry construction. Cement mortar batch leveling requires the use of a large amou...
