Problems solved by technology

[0003] All residues of sludge and non-organic substances produced by water purification plants or incineration plants are classified as waste. At present, most waste is disposed of by landfill or incineration, and only a small amount of waste is recycled and reused. Disposal of waste through landfill or incineration will seriously pollute the environment
[0004] Construction materials also produce a lot of waste in the process of production, processing and use. The construction waste is mainly disposed of by incineration or landfill, which has a serious impact on the environment.

Description

Technical field [0001] The invention belongs to the technical field of building materials, and specifically relates to a thermal insulation building material containing waste and a preparation method thereof. Background technique [0002] Wood building materials occupy a large proportion of building materials. As the use of building materials increases, the consumption of wood resources has also increased significantly. As a non-renewable resource, wood is facing the danger of resource exhaustion, and it is necessary to find alternatives. [0003] All residues of sludge and non-organic matter produced in water purification plants or incineration plants are classified as waste. At present, most of the waste is disposed of by landfill or incineration, and only a very small amount of waste is recycled and reused. Disposal, and the disposal of waste through landfill or incineration will seriously pollute the environment. [0004] Many waste materials are also generated during the produc...
