Embodiment 1

[0026] A production process of a bio-based mycelium material, comprising the following steps:

[0027] (1) Preparation of cultivation substrate: The cultivation substrate is composed of the following components by weight percentage: 92% corn stalks, 4% corn flour, and 4% bran. Corn stalks are crushed to a particle size of 1 cm and mixed with corn flour, Mix the bran, then add water to adjust the water content to 30%, mix well, put the cultivation substrate into a mold with a size of 13.2cm*26cm*3.5cm, sterilize it at high temperature and cool it down to room temperature for use;

[0028] (2) Inoculation: In a sterile environment, insert the oyster mushroom strain into the cultivation medium, and then move it into the cultivation room for cultivation;

[0029] (3) Cultivation: Cultivate for 20 days under the conditions of temperature less than 25 degrees, humidity less than 70%, dark, sterile, and well ventilated.

[0030] (4) Drying: Remove the culture room, take the material...

Embodiment 2

[0032] A production process of a bio-based mycelium material, comprising the following steps:

[0033] (1) Cultivation substrate preparation: 46% corn stalks, 46% hardwood sawdust, 4% corn flour, 4% bran, crush corn stalks and hardwood sawdust to a particle size of 1 cm and mix with corn flour, Mix the bran, then add water to adjust the water content to 30%, mix well, put the cultivation substrate into a mold with a size of 13.2cm*26cm*3.5cm, and cool it down to room temperature for use after high-temperature sterilization;

[0034] (2) Inoculation: In a sterile environment, insert the oyster mushroom strain into the cultivation medium, and then move it into the cultivation room for cultivation;

[0035] (3) Cultivation: Cultivate for 15 days under conditions of temperature less than 25 degrees, humidity less than 70%, dark, sterile, and well ventilated.

[0036] (4) Drying: Remove the culture room, take the material out of the mold and dry it until the moisture content is le...

Embodiment 3

[0038] A production process of a bio-based mycelium material, the steps are the same as in Example 1, the difference is that in step (3) the carbon dioxide is preferably controlled at 8000PPM and the light is less than 50 lux during the cultivation, and the cultivation is carried out for 17 days.

[0039] Conclusion: The bio-based mycelium material produced by the implementation of Case 1-3 has a neat appearance, uniform, dense and pollution-free mycelium growth; the product specifications are uniform, the weight is basically the same, and the specific density and size are respectively: 0.104g / cm 3 ,13.2cm*26cm*3.5cm; 0.142g / cm 3 ,13.2cm*26cm*3.5cm;

[0040] 0.142g / cm 3 ,13.2cm*26cm*3.5cm.

[0041] After testing, the comparison results with "GB / T6343-1995", "GB / T8813-1988" and "GB / T8812-1988" are as follows:

[0042]

[0043] The above comparison results show that the bio-based mycelium material prepared by this process can completely replace EPS foam products.

Abstract

The invention provides a production process for a biologic mycelium material. According to the core technology, several large fungi with high resistance to other fungi and high growth speed are selected, and straw of wheat, rice and other crops is shaped in an adhesively-bonded mode by making use of biological characteristics of mycelia. According to the material, waste crop straw and wood bits serve as main raw materials, pollution is not generated in the production process, energy consumption is low, the raw materials can be completely degraded 180 days after being discarded, technical indexes exceed the national standard of an EPS board, and therefore the material is a substitute for EPS foamed plastic and can be widely applied to the fields of packaging, construction, ocean, home furnishing and the like.

Description

technical field [0001] The invention relates to the field of biopolymer materials, in particular to a method for producing bio-based mycelium materials using corn stalks and sawdust as raw materials. Background technique [0002] EPS board (also known as benzene board) is the abbreviation of expandable polystyrene board. It is a polystyrene foam plastic sheet with a closed-cell structure obtained by heating and pre-foaming expandable polystyrene beads and then heating them in a mold. It is made from raw materials after pre-hairing, curing, molding, drying and cutting. It can not only be made into foam products of different densities and shapes, but also foam boards of various thicknesses. Widely used in construction, heat preservation, packaging, refrigeration, daily necessities, industrial casting and other fields. It can also be used in the manufacture of display venues, commodity cabinets, advertising signs and toys. In order to meet the national building energy-savin...
