Abstract

The invention discloses a biomass building insulation board made of hemp straw, which belongs to the field of building materials. Its structure mainly includes a biomass insulation layer made of hemp straw, and its components are: hemp straw particles 30‑ 50%, inorganic thermal insulation particles 10-25%, matrix material kaolin 30-60%, of which hemp straw and inorganic thermal insulation materials act as filling and thermal insulation, and kaolin acts as a binder and also has a certain thermal insulation effect. The biomass insulation layer is made by compaction, air-drying, stamping and other processes, and then the biomass insulation layer and the surface layer structure are combined to prepare the biomass building insulation board. The insulation board has good heat insulation, high structural strength and sound insulation effect. Good, antibacterial and other advantages.

Description

technical field [0001] The invention relates to the field of material synthesis processing and construction technology, and is a novel biomass composite thermal insulation building material. technical background [0002] Green building is an important part of my country's construction of an ecologically civilized society, and it is also one of the main trends in future architectural development. my country's green building emphasizes "four sections and one environmental protection", that is, water saving, energy saving, land saving, material saving and environmental protection. Among them, saving building materials is the biggest contribution of the construction industry to environmental protection. The current building materials in my country are mainly concrete, stone, Non-degradable materials such as bricks and tiles. In the early 21st century, my country's construction waste was mainly used for landfill of highway foundations, but at present and for a long time in the fu...
