Description
Technical field
The invention belongs to environmentally friendly biomass field of packaging material, more particularly to one kind is based on wheat stalk
Fungi based biomass packaging material of material and preparation method thereof.
Background technology
At present, both at home and abroad to the packaging of commodity mainly using polystyrene (EPS), polyethylene foam cotton (EPE) or poly-
The composites such as propylene (PP).Although this type of foam has the advantages that light weight, density be little, shock-absorbing capacity is good, using losing
Natural degradation is difficult after abandoning, recycling is difficult, so as to be formed environmentally hazardous " white pollution ".At this stage, Europe, the U.S.,
The developed countries such as Japan make laws and forbid the industrial products import of the bubble wrap such as EPS, or are limited by improving environmentally friendly tax
System and superseded foamed plastics as packaging material product import.According to the statistics made by the departments concerned, China about 7,400,000,000 dollars of business every year
Product are obstructed because being provided without environmental protection package, bring huge economic loss.To realize environmentally friendly, resource-conserving society
Meeting, studies, develops, produces, promotes and significant using environment-friendly package material.
China is large agricultural country, biological material very abundant.According to statistics, the product of the material of the annual agricultural crop straw of China
Amount is up to hundred million tons of 8-9, using about 700,000,000 tons of stalk resource.In order to realize that stalk resource is recycled, National Development and Reform Committee, agricultural
Combine in issue in 2 months 2009 in portion《Instruction with regard to working out stalk comprehensive utilization planning》, set up more perfect in the whole nation
Stalk industrialization comprehensive utilization general layout, especially emphasis solves the stalk that corn, wheat, paddy rice etc. are had a large capacity and a wide range.Wheat is for I
The second largest cereal crops of state, the yield of annual wheat stalk reaches 1.3 hundred million tons.Wheat stalk is nutritious, content of cellulose
40%-45%, hemicellulose level 24%-28%, content of lignin 19%-25%.At present, part wheat stalk mainly by with
In there is the aspects such as artificial board of straw, recovery energy, straw feed, planting edible mushroom and straw-returning；But it is annual to also have
Considerable fraction of wheat stalk is incinerated, this not only waste of resource, while also resulting in the pollution of environment.Therefore, how to fill
Divide using the wheat straw resource of China, be a urgent problem.
China's fungus resource enriches, wherein, edible fungus resource accounts for the 50% of whole world total amount, and many fungies have original
Material utilization scope is wide, and mycelium is flourishing, strong mycelium kink ability and the advantages of high intensity.Therefore, with the wheat of China's abundant
Stalk resource is primary raw material, is inoculated with specific fungi, develops new packaging material, reaches the mesh of resources circulation efficient utilization
's.
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；Patent of invention (CN106148199A) is a kind of to utilize macro fungi mycelia system
The method of standby degradable padded coaming, a kind of production technology of bio-based mycelia material of patent of invention (CN105660176A) and
A kind of employing agriculture discarded object of patent of invention (CN104401585A) prepares the outward appearance that method of amortizing packaging material etc. prepares material
Shaping is poor, and shock-absorbing capacity and mechanical property are poor, and easily cause miscellaneous due to being inoculated with using liquid spawn during preparation
Bacterium pollutes.
Therefore, the present invention is not enough for more than, proposes a kind of fungi based biomass packing timber with wheat stalk as major ingredient
Material and preparation method thereof, prepares that shock-absorbing capacity is good, intensity using the microorganism fungus kind that mycelium is flourishing, mycelium kink ability is strong
Good, outward appearance forming, the biomass packaging material of anti-mildew good waterproof performance.
In sum, wheat stalk is incinerated, not only waste of resource, while also resulting in environmental pollution.
