Problems solved by technology

[0005] In view of this, the present invention aims to propose a fiberboard based on fungus and its preparation method. In the production process of fiberboard, no chemical adhesive is added, and the mycelium produced by fungi is effectively used instead of adhesive to bind waste particles. Together, the fiberboard is prepared, which solves the problems of non-degradable, polluting the environment, and high cost of the current fiberboard.

Embodiment 1

[0036] This example provides a method for preparing fiberboard based on fungus. Compared with the traditional fiberboard production process, agricultural waste is used as raw material, and in the production process, fungal mycelium grows rapidly and mycelium has strong kink strength. characteristics, preparation of agricultural waste into hardboard material. The agricultural waste described in this embodiment mainly includes straw, which usually refers to the remaining part of wheat, rice, corn, potatoes, rapeseed, cotton, sugarcane and other crops (usually coarse grains) after harvesting seeds, and straw contains high lignin and cellulose. The lignocellulosic debris of the straw can be used as the main raw material for the fermentation and cultivation of fungi. The mycelia grown by the fungus wrap the lignocellulosic debris in a net shape to form a whole, and then dry and shape to obtain a composite fiberboard. The agricultural wastes described in this embodiment can also be...

Embodiment 2

[0071] The difference between this embodiment and embodiment 1 lies in step S2: preparation and sterilization of medium:

[0072] In this embodiment, the medium dry material includes 90% by mass of agricultural fiber material, 6% by mass of powder containing vegetable protein, and 4% by mass of auxiliary material. The auxiliary materials include carbohydrates and pH regulators, wherein the mass fraction of carbohydrates in the dry medium is 3%, and the mass fraction of the pH regulator in the dry medium is 1%. Carbohydrates can be monosaccharides or polysaccharides. The water-soluble monosaccharide used in this embodiment can be sucrose, glucose, etc., and the pH regulator can be quicklime, gypsum, sodium bicarbonate, etc.; in this embodiment Among them, preferably, the water-soluble monosaccharide is glucose, and the pH regulator is quicklime.

[0073] Concrete, material preparation stage: the agricultural fiber material after the pretreatment of 90 parts by weight, 6 parts ...

Embodiment 3

[0078] The difference between this embodiment and the above lies in step S2: preparation and sterilization of medium:

[0079] In this embodiment, the medium dry material includes 88% by mass of agricultural fiber material, 8% by mass of powder containing vegetable protein, and 4% by mass of auxiliary material. The auxiliary materials include carbohydrates and pH regulators, wherein the mass fraction of carbohydrates in the dry medium is 3%, and the mass fraction of the pH regulator in the dry medium is 1%. Carbohydrates can be water-soluble monosaccharides or polysaccharides. Water-soluble monosaccharides are used in this embodiment. Water-soluble monosaccharides can be sucrose, glucose, etc., and pH regulators can be quicklime, gypsum, sodium bicarbonate, etc.; In an embodiment, preferably, the water-soluble monosaccharide is glucose, and the pH regulator is quicklime.

[0080] Specifically, the material preparation stage: the pretreated agricultural fiber material of 88 pa...

Abstract

The invention provides a fiberboard based on fungi and a preparation method of the fiberboard. The preparation method comprises the steps that agricultural fiber matter is pretreated, the pretreated agricultural fiber matter is evenly mixed with powder containing vegetable proteins and auxiliary materials to form a culture medium dry material, water is added, even mixing is conducted to form a culture medium, and the culture medium is loaded into a sterilization wrap to be sterilized; then, the culture medium cooled to the room temperature is inoculated with the fungi and then placed in a culture room for culturing till the culture medium is covered with mycelia; a mold is filled with the culture medium, and culturing is continued till mycelia overgrow on the culture medium in the mold again; and the fiberboard is prepared through drying demolding or hot-press forming. According to the preparation method of the fiberboard, no chemical adhesive is added, the mycelia of the fungi are effectively utilized to replace a tackifier, waste particles are bonded together to prepare the fiberboard, and agricultural waste resources are comprehensively utilized.

Description

technical field [0001] The invention relates to the technical field of fiberboards, in particular to a fungus-based fiberboard and its preparation. Background technique [0002] my country is a large agricultural country, and the types and yields of crops such as wheat, rice, and corn are very rich. However, according to relevant incomplete statistics, the utilization rate of crop waste (such as straw, chaff, saw foam, etc.) in my country is very low. Untreated waste is discarded or incinerated, which not only causes waste of resources but also increases carbon emissions and pollutes the environment. [0003] According to statistics, my country has become the world's largest producer and consumer of man-made fiberboard, with an output value exceeding 100 billion yuan. Although the output of my country's man-made fiberboard continues to increase, it still cannot meet the market demand, and there is also a serious shortage of raw material supply. In the prior art, although th...
