Abstract

The invention relates to a fungus-based biomass thermal-insulating material mainly prepared from wheat straw and a preparation method of the material. The fungus-based biomass thermal-insulating material is prepared from, in parts by mass, 45-85 parts of wheat straw, 5-10 parts of shredded straw, 5-25 parts of rice bran and 5-20 parts of a biomass thermal-insulating material additive. The preparation method comprises preparation of compost, sterilization treatment and inoculated culture. Biomass materials such as the wheat straw and the like are taken as raw materials and converted into the environment-friendly biomass thermal-insulating material by using the characteristics that fungus hyphae grow quickly and have high twisting capacity; the preparation method of the biomass thermal-insulating material is simple, the production cost is low, the thermal-insulating performance is good, the strength is high, and the environment-friendly biomass thermal-insulating material has good market prospect and potential.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly biomass thermal insulation materials, and in particular relates to a fungus-based biomass thermal insulation material with wheat straw as the main material and a preparation method thereof. Background technique [0002] With the rapid development of social economy, people's requirements for architecture are getting higher and higher, which makes the construction industry develop rapidly. At present, most of the exterior wall materials of buildings in my country are mainly reinforced concrete and solid clay bricks. The thermal conductivity of the wall is high. After being irradiated by the sun, the "thin" buildings can easily absorb solar heat and radiate to Indoor air increases the room temperature. According to reports, the energy consumption per unit building area for heat insulation in my country is about three times that of developed countries under similar climate conditions, and...
