Description
Technical field
The invention belongs to biological material fields, and in particular to a kind of preparation method of environment protection biological scutum and its should
With.
Background technology
China is large agricultural country, about generates 700,000,000 tons of stalk every year.Minerals, crude fibre and lignin are rich in stalk,
It is a kind of ideal timber substitute.Forest reserves shortage, the situation of wood supply anxiety can be alleviated；Simultaneously, it is ensured that product
Environmentally friendly friendly, convey low-carbon environment-friendly, it is naturally simple to design and life idea, huge environmental benefit, ecology can be generated
Benefit and economic benefit.
The research of the artificial stalk board in China is started from the 1950s, starting to build stalk board assembly line in the seventies.At present,
Stalk board on the market is mainly made up of hot pressing after adding various adhesives to stalk fibre, and common adhesive has ureaformaldehyde
Resin adhesive (UF), phenolic resin adhesive (PF) and melamine-formaldehyde resin adhesive stick agent (MF) etc.；However, due to that can release
The formaldehyde gas of free state is released, not only pollutes environment, but also have stronger harm to health.
Invention content
For this purpose, the technical problems to be solved by the invention be to overcome in the prior art conventional panels have formaldehyde, not ring
It protects, the technical bottlenecks such as toxic, with high costs to body, so as to propose a kind of preparation method of environment protection biological scutum and its should
With.
In order to solve the above technical problems, the invention discloses a kind of preparation method of environment protection biological scutum, including as follows
Step：
S1, stalk fibre is prepared, dry stalk is crushed into the stalk fibre for grain size 5-50mm；Stalk fibre is corn
At least one of stalk, wheat stalk, rice straw, soybean stalk, bagasse；
S2, sterilization treatment add in rice bran and mixing in the stalk fibre prepared to step S1, obtain pre-composition, to described
It is added in pre-composition dissolved with quick lime and the aqueous solution of land plaster, until stalk fibre water suction reaches saturation, water content is in 56-
64%, laggard horizontal high voltage sterilization treatment obtains sterile material；
S3, fungal mycelium is prepared, the base material for covering with fungal mycelium is placed in partial sterilization material surface, and in base material
Surface covers remaining sterile material, cultivates at room temperature；
After hypha,hyphae covers with the sterile material, place is dried to the sterile material for covering with hypha,hyphae in S4, drying
Reason；
Dried material compression is handled, and is surface modified by S5, compression.
Preferably, in the stalk fibre that the step S1 is prepared, the stalk fibre accounting that grain size is 5-20mm is 55-
75%, the stalk fibre accounting that grain size is 20-50mm is 25-45%.
Preferably, in the step S2, in the aqueous solution mass percent of quick lime be 1.2-1.7%, the stone
The mass percent of cream powder is 0.6-1.4%.
Preferably, in the step S2, the rice bran quality of addition is the 11-23% of stalk section fiber quality.
Preferably, the high pressure sterilization processing described in the step S2 be using steam-type high-pressure sterilizing pot,
Sterilize 1.2-1.6h under the pressure of 0.07Mpa-0.14Mpa.It is preferred that the 1.4h that sterilizes under the conditions of 0.12Mpa.
Preferably, the step S3 is specifically, be packed into sterile material after cooling into the mold after sterilizing, until being filled to
During the half of die depth, the flax fiber cloth base material for covering with fungal mycelium is laid on the sterile material, until complete
Then the top half of the remaining vacancy of mold is filled up and is pressed with sterile material again by the upper surface of the entire sterile material of all standing
Real postposition is cultivated at room temperature.
Preferably, material is compressed 30-50s by the boil down to described in the step S5 under 100-500 tons of pressure.
Preferably, the drying described in the step S4 is natural drying, hot air circulation is dry, microwave drying or vacuum are done
It is dry.
More preferably, the surface modification is slice leveling processing or pasting processing.
The invention also discloses application of any one preparation method in house ornamentation, building materials and household manufacturing field.
The above technical solution of the present invention has the following advantages over the prior art：The method of the invention is without using any
Chemical adhesive, directly by the use of agricultural crop straw as skeleton, fungal mycelium is natural glue, forms composite material；Institute
It is the material fully biodegradable of production and low energy consumption, safe and non-toxic, and have higher mechanical property；The manufacturing process only needs
Stalk fibre is handled, is sterilized, plants fungal mycelium, drying, compression.Whole process energy consumption is relatively low, utilizes fungi bacterium
Filament produces the good biological scutum of mechanical property as natural " viscous glutinous agent ", which can be used for furniture, decoration,
Packaging etc.；Meanwhile realize the comprehensive utilization of stalk fibre resource, turn waste into wealth, avoid and abandon or burn generation carelessly
Pollution, protect environment, promote sustainable development.This method is simple, production cost is low, intensity is high, compactness is a kind of well
The biological scutum of the environment of great market prospects and potentiality friend；With very big market prospects and economic value.
