Description
Technical field
The invention belongs to environmentally friendly biomass field of packaging material, more particularly to one kind is with bagasse as major ingredient
Fungi based biomass packaging material and preparation method thereof.
Background technology
The commodity such as electronic product, household electrical appliance and engineering goods all be unable to do without packaging.At present using most industry bags
Package material is mainly polystyrene (EPS) or polyethylene foam cotton (EPE).But this kind of amortizing packaging material abandon using after in
It is difficult under natural conditions to decompose, in the course of time, will cause to society " white pollution "；Burning disposal also can be caused seriously to environment
Pollution.Therefore, the new environmentally friendly packing material of application is great come the Research Significance that substitutes 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, NFE 42%, thick protein 2.0%, crude fat 0.7%, cellulose
44%-46%, hemicellulose 23%-25%, lignin 18%-20%, it is nutritious, thus the recycling side of bagasse
Formula is a lot.At present, the state such as Argentina, Colombia, Mexico, India, Australia produces newsprint and each using bagasse
Class Cultural Paper, or produce high-quality art paper etc. with bleaching bagasse pulp mixed bleach softwood pulp；Brazil, the U.S., Australia
Sugar refinery of the countries such as big Leah passes through high temperature using bagasse, autoclaving is expanded or fermented process is used as ox, sheep, fish, shrimp
Feed.It is reported that, the bagasse of current China 90% is used as fuel, and the boiler for sugar refinery generates electricity and supplies steam, and remains
10% bagasse of remaininging is primarily used to the cultivation of edible mushroom, papermaking and production animal feed etc., and cyclic utilization rate is low, because
This, rational exploitation and utilization bagasse resource is the needs built a resource-conserving and environment-friendly society.At present, both at home and abroad
There is researcher to begin through addition chemical synthetic material bagasse to be made into biological material and makes anti-using bagasse
Fiery material, but rarely found bagasse is used to prepare biological material as the report of packaging material.
Research shows that China's fungus resource enriches, and many fungies have raw material utilization scope wide, and mycelium is flourishing, bacterium
The characteristics of filament kink is fast, intensity is high.Simultaneously the hyphal cell wall of some higher funguses is made up of chitin or cellulose, internal
Containing a large amount of fungi polysaccharides, with good cementing effect.
At present, using microorganism fungus kind prepare the report of packaging material both at home and abroad, but still there are the not enough ground of many
Side.Such as：A kind of method of inoculation edible fungus species culture degradable package material of patent of invention (CN104025909A), its making
Packaging material elasticity and water resistance 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) bio-based mycelia material
Production technology and a kind of employing agriculture discarded object of patent of invention (CN104401585A) prepare the system such as method of amortizing packaging material
The outward appearance shaping of standby material is poor, and shock-absorbing capacity and mechanical property are poor, and due to being connect using liquid spawn during preparation
Kind, easily cause living contaminants.
Therefore, the present invention is not enough for more than, proposes a kind of fungi based biomass packaging material with bagasse as major ingredient
And preparation method thereof, prepare shock-absorbing capacity using mycelium prosperity, the mycelium kink microorganism fungus kind that ability is strong, intensity is high
It is good, intensity is good, density is little, outward appearance forming, the biomass packaging material of anti-mildew good waterproof performance.So as to the resource of bagasse is excellent
Gesture is converted into product advantage, reaches resources circulation efficient utilization.
In sum, prior art can not utilize specific fungi, be new environmentally friendly biology by bagasse exploitation
Material, by resources advantage product advantage is converted into, so as to reach resources circulation efficient utilization.
