Embodiment 1

[0022] Embodiment 1 This embodiment discloses a method for preparing a biomass board, the method is as follows:

[0023] S1. Straw fiber preparation: Use a straw fiber pulverizer to process the dried straw into straw fibers with a particle size of 5mm-50mm. (Straw fiber is at least one of corn straw, wheat straw, rice straw, soybean straw, and bagasse ); Among them, the proportion of straw fibers with a particle size of 5mm-20mm and 20mm-50mm are 65% and 35% respectively;

[0024] S2. Sterilization: add 15% rice bran of the dry weight of the straw to the straw fiber, and after mixing, add an aqueous solution of 1.5% quicklime and 1% gypsum powder to the straw fiber until the straw fiber absorbs water and reaches saturation. When the amount of water reaches 60%, the material is sterilized by a steam autoclave (pressure is 0.12Mpa, time is 1.4h).

[0025] S3. Preparation of fungal mycelium: Fill the sterilized mold with the cooled sterilized material until it is half the depth of the ...

Embodiment 2

[0030] Embodiment 2 This embodiment discloses a method for preparing a biomass board, the method is as follows:

[0031] S1. Straw fiber preparation: Use a straw fiber pulverizer to process the dried straw into straw fibers with a particle size of 5mm-50mm. (Straw fiber is at least one of corn straw, wheat straw, rice straw, soybean straw, and bagasse ); Among them, the proportions of straw fibers with a particle size of 5mm-20mm and 20mm-50mm are 55% and 45% respectively;

[0032] S2. Sterilization: Add 11% rice bran of the dry weight of the straw to the straw fiber. After mixing, add an aqueous solution of 1.7% quicklime and 0.6% gypsum powder to the straw fiber until the straw fiber reaches saturation. When the water content reaches 56%, the material is sterilized with a steam-type autoclave (pressure is 0.14Mpa, time is 1.2h).

[0033] S3. Preparation of fungal mycelium: Fill the sterilized mold with the cooled sterilized material until it is half the depth of the mold, then spr...

Embodiment 3

[0038] Embodiment 3 This embodiment discloses a method for preparing a biomass board, the method is as follows:

[0039] S1. Straw fiber preparation: Use a straw fiber pulverizer to process the dried straw into straw fibers with a particle size of 5mm-50mm. (Straw fiber is at least one of corn straw, wheat straw, rice straw, soybean straw, and bagasse ); Among them, the proportion of straw fibers with a particle size of 5mm-20mm and 20mm-50mm are 75% and 25% respectively;

[0040] S2. Sterilization: Add 23% rice bran of the dry weight of the straw to the straw fiber. After mixing, add an aqueous solution of 1.2% quicklime and 1.4% gypsum powder to the straw fiber until the straw fiber is saturated with water. When the amount of water reaches 64%, the material is sterilized by a steam-type autoclave (pressure is 0.07Mpa, time is 1.6h).

[0041] S3. Preparation of fungal mycelium: Fill the sterilized mold with the cooled sterilized material until it is half the depth of the mold, then...

Abstract

The invention belongs to the field of biological new materials and particularly relates to a preparation method of an environment-friendly biomass board and application thereof. The preparation methodcomprises the following steps that straw fibers are prepared; sterilization treatment is performed; fungus mycelium is prepared and cultured at the room temperature; drying treatment is performed; and compression treatment and surface finish are performed in sequence. According to the method, no chemical adhesive is used, crop straw is directly utilized as a framework, the fungus mycelium is taken as the natural adhesive, and a composite material is formed; the produced material is completely biodegradable, low in energy consumption, safe, free of poison and high in mechanical property; the biomass board can be used for the aspects of furniture, decoration, packaging and the like; and straw fiber resources are comprehensively utilized, wastes are turned into wealth, pollution generated byrandom discarding or incineration is avoided, the environment is protected, and sustainable development is promoted. The method is easy, the production cost is low, the strength is high, the compactness is good, and the biomass board is an environment-friendly biomass board which is extremely high in market prospect and potential.

Description

Technical field [0001] The invention belongs to the field of new biological materials, and specifically relates to a preparation method and application of an environment-friendly biomass board. Background technique [0002] my country is a big agricultural country, producing about 700 million tons of straw every year. Straw is rich in minerals, crude fiber and lignin, which is an ideal substitute for wood. It can alleviate the shortage of forest resources and the tight supply of wood; at the same time, ensure that the product is environmentally friendly, convey low-carbon environmental protection, natural and simple design and life concepts, which can generate huge environmental, ecological and economic benefits. [0003] The research of artificial straw board in my country began in the 1950s, and the straw board production line was built in the 1970s. At present, the straw board on the market is mainly made by adding various adhesives to the straw fibers and then hot pressing. C...
