Description
Technical field
The invention belongs to environmentally friendly biomass field of packaging material, more particularly to one kind is using bagasse as major ingredient
Fungi based biomass packaging material and preparation method thereof.
Background technique
The commodity such as electronic product, household electrical appliance and engineering goods all be unable to do without packaging.Most commonly used industry packet at present
Package material is mainly polystyrene (EPS) or polyethylene foam cotton (EPE).But after this kind of amortizing packaging material use abandon in
It is difficult under natural conditions to decompose, over time, it will be caused to society " white pollution "；Burning disposal can also cause seriously to environment
Pollution.Therefore, the novel environmentally friendly packing material of application is great come the research significance for substituting bubble wrap.
China is third place in the world cane planting big country, reaches more than 150 ten thousand hectares, produces about 28,000,000 tons of bagasse per year.According to survey
It is fixed, bagasse 90%-92% containing dry matter, nitrogen-free extracts 42%, thick protein 2.0%, crude fat 0.7%, cellulose
44%-46%, hemicellulose 23%-25%, lignin 18%-20% is full of nutrition, thus the resource utilization side of bagasse
There are many formula.Currently, the states such as Argentina, Colombia, Mexico, India, Australia are using bagasse production newsprint and respectively
Class Cultural Paper, or the art paper etc. with bleaching bagasse pulp mixed bleach softwood pulp production high quality；Brazil, the U.S., Australia
Sugar refinery of the countries such as big Leah is used as ox, sheep, fish, shrimp by high temperature, autoclaving extruding or fermented processing using bagasse
Feed.It is reported that the bagasse in China 90% is used as fuel at present, boiler power generation and supply steam for sugar refinery, and remain
10% bagasse of remaininging is primarily used to the cultivation of edible mushroom, and papermaking and production animal feed etc., cyclic utilization rate is low, because
This, rational exploitation and utilization bagasse resource is the needs built a resource-conserving and environment-friendly society.Currently, both at home and abroad
There is researcher to begin through addition chemical synthetic material biological material is made in bagasse and is made using bagasse anti-
Fiery material, but rarely found bagasse is used to prepare report of the biological material as packaging material.
Studies have shown that China's fungus resource is abundant, and many fungies have raw material utilization scope wide, mycelium prosperity, bacterium
The feature that filament kink is fast, intensity is high.The hyphal cell wall of some higher funguses is made of chitin or cellulose simultaneously, internal
Containing a large amount of fungi polysaccharides, there is good cementing effect.
Currently, have the report for preparing packaging material using microorganism fungus kind both at home and abroad, but still there are many insufficiently
Side.Such as: a kind of method for being inoculated with edible fungus species culture degradable package material of patent of invention (CN104025909A), production
Packaging material elasticity and waterproof performance it is poor, sample rate is big；Patent of invention (CN106148199A) is a kind of using large-scale
Fungal mycelium prepares the method for degradable padded coaming, a kind of patent of invention (CN105660176A) biology base mycelia material
The system such as production technology and a kind of method that amortizing packaging material is prepared using agriculture waste of patent of invention (CN104401585A)
The appearance molding of standby material is poor, and cushion performance and mechanical property are poor, and due to being connect using liquid spawn during preparation
Kind, it be easy to cause living contaminants.
Therefore, the present invention against the above deficiency, proposes a kind of using bagasse as the fungi based biomass packaging material of major ingredient
And preparation method thereof, mycelium kink ability strong, intensity high microorganism fungus kind flourishing using mycelium prepares cushion performance
It is good, intensity is good, density is small, appearance forming, anti-mildew good waterproof performance biomass packaging material.To which the resource of bagasse is excellent
Gesture is converted into product advantage, reaches resources circulation and efficiently utilizes.
In conclusion the prior art cannot utilize specific fungi, bagasse is developed as novel environmentally friendly biology
Resources advantage is converted product advantage by material, efficiently utilizes to reach resources circulation.
