Description
Technical field
The present invention relates to the preparation method of a kind of fruit dedicated biomass amortizing packaging material, belong to packaging material preparation neck
Territory.
Background technology
Packaging group product is mainly Plastic at present, owing to the garbage of Plastic packaging is the most recyclable, non-degradable, its
A large amount of use causes serious white pollution, brings huge ambient pressure.Owing to most of plastic packing products are originated
In non-renewable petroleum resources, therefore find a kind of new effective method to process the dirt that plastic package material causes
Dye, breaks away from simultaneously and petroleum based material is depended on unduly the hot issue becoming the whole world.Modern industry since 18th century,
Also the problem in terms of resource and ecological environment, especially stone has been brought while creating huge material wealth for the mankind
Changing the shortage of resource and the pollution etc. to environment thereof, the survival and development of the mankind in serious threat.With green for this, substitute non-again
The raw fossil resources with heavily contaminated, to meet the research and development trend that the mankind have become important to the demand of resource and material.
Herba Eichhorniae contains cellulose, the hemicellulose of 48.7% and the lignin of 3.5% of 18.7%.These compositions are all
Prepare the effective ingredient of biomass composite.The each basic ring of repetitive of its fiber surface macromole contains 3 hydroxyls
Base, makes fiber have stronger polarity in preparation process, between fiber and between fiber and adhesive in conjunction with providing very
Good basis.It addition, the hemicellulose contained in a large number in Herba Eichhorniae can reduce the deformation of goods when machine-shaping, and improve
The load-bearing capacity of material, is also good natural glue simultaneously.Therefore, water plant is used to prepare material and land based vegetation phase
Ratio can reduce the addition of adhesive, improves the effect of the strength of materials.
Summary of the invention
The technical problem that present invention mainly solves: be based on plastics for the most common fruit packaging material, source
In non-renewable petroleum resources, there is non-degradable, serious white pollution, and conventional packaging material after abandonment, can be caused
The defect of function singleness, it is provided that the preparation method of a kind of fruit dedicated biomass amortizing packaging material.The method is with biomass
Material Feng Weilian is raw material, prepares the fiber rich in active group through making beating brooming, then it is mixed through root nodule with konjak starch
Bacterium is modified, and the effect at auxiliary agent is betted and molded system, the most i.e. obtains biomass amortizing packaging material.The present invention utilizes phoenix tail lotus fine
The activity hydroxy that dimension is abundant has high polarity to improve the load-bearing capacity of material, and konjak starch is solid through the biology of root nodule bacteria
Nitrogen effect accesses hydrophile amino in base material, improves material water-retaining property, is possible to prevent scattering and disappearing of fruit transportation process moisture, improves
Fruit freshness, more foamed be dried make material internal have abundant hole, improve its shock-absorbing capacity, both solved traditional
Plastic fruit packaging material derive from non-renewable petroleum resources, there is non-degradable, can cause serious white after abandonment
Pollute problem, compensate for again the defect that fruit packaging material function is single, i.e. available buffer shockproof, also can water-holding fresh-keeping, and
It is biodegradable that the present invention prepares packaging material, to environment without any harm.
