Description
Technical field
The present invention relates to field of packaging material, a kind of method of discarded paper packing material regeneration.
Background technology
Along with economic develops rapidly, the theory such as low-carbon economy, energy saving economy, green economy is gradually rooted in the hearts of the people.Environmental protection
Problem is a large focal spot problem of the world today.Along with countries in the world reinforcement continuous to environmental consciousness and waste paper recycle skill
The fast development of art, overseas enterprise payes attention to waste paper the most more and more and recycles.China paper industry the Tenth Five-Year Plan (2001-2005) proposes,
Require that waste paper utilization proportion brings up to 2010 48% from 41% in 2000, within 2015, reach 55%, the most domestic waste paper profit
Within 2015,43% is reached with proportion.China's waste paper dosage increases to 16,380,000 tons of calendar year 2001 from the 8100000 of nineteen ninety-five tons, 5 years
Turn over some.But compared with the country many with more external waste paper dosage, there is also gap.
The recovery method of existing a kind of waste paper packaging material, comprises the following steps: waste and old packaging material are cut into little by (1)
Sheet, cleans, goes the removal of impurity, dries；(2) material flakes is put in water-soluble alkali solution, stir under 50～100 DEG C of constant temperatures
Mix, make aqueous slkali that the paper packing material of waste and old packaging material is dissolved as paper pulp fiber；Obtain separating mixture；(3) will separate
Mixture sends into deflaker, makes paper pulp fiber dispersion discongest, obtains discongesting mixture；Mixture will be discongested and move into scummer
In, respectively obtain paper pulp fiber after process, be then baked to, obtain the paper pulp of regeneration.The paper pulp that said method obtains is for changing
Learning slurry, its secondary stock quality progressively decays, and causes under the tightness of its recycled writing paper, tensile strength, resistance to broken ability and folding number
Fall.And regenerated paper pulp contains the extract of substantial amounts of lignin, hemicellulose and dissolution, affect paper machine and manufacture paper with pulp and the matter of page
Amount, reduces paper formation, opacity, brightness and intensity, produces aperture and dim spot.
Summary of the invention
It is an object of the invention to utilize the secondary stock repulping of mechanical feedback to solve in existing waste paper recovery method change
The secondary stock quality learning slurry repulping declines problem,.
A kind of method that it is a further object to provide discarded paper packing material regeneration, reduces recycled waste paper
The harmful effect that in slurry, the extract of lignin, hemicellulose and dissolution causes.
To achieve these goals, the technical solution of employing is:
A kind of method of discarded paper packing material regeneration, it is characterised in that comprise the steps of:
1), the pretreatment of discarded paper packing material
Waste paper being transported to hydrabrusher and carries out size degradation, hydrabrusher carries out deinking of pulling an oar to waste paper；
2), the decomposition of discarded paper packing material
Step 1) paper pulp that obtains separates impurity through dither screening, obtains separating mixture, and high temperature constant temperature stirs
After, separating mixture now is sent into deflaker, makes paper pulp fiber dispersion discongest, obtain discongesting mixture；
3), the purification of paper pulp
By step 2) in mixture of discongesting put into sand cleaning machine, through process obtain paper pulp, standby；
4), by starch and cold water 1: 4 mixed dissolution high temperature gelatinizing by weight, after obtaining dextrin, by starch gelatinization
Liquid and straw, by weight 1: 1 mixing and stirring, obtain mixture；
5), by step 3) in the paper pulp that obtains and step 4) in after mixture mix and blend, put into mould composite molding.
Preferably, step 2) in whipping temp be 70～100 DEG C, constant temperature has been regulated by water-bath.
Preferably, step 4) in gelatinization point be 90～100 DEG C.
Preferably, step 4) in straw be Caulis et Folium Oryzae, wheat straw, corn straw or the one of which of Caulis Sacchari sinensis straw or
Multiple.
Preferably, step 4) in straw need dry or dry and be processed into crushing straw.
Preferably, crushing straw is straw and the straw of a length of below 0.5cm of a length of 1-2cm.
The beneficial effect that the present invention can produce:
1, the present invention reclaims and utilizes waste paper packaging material, economizes on resources, and reduces the cutting capacity of trees.
2, the present invention utilizes straw and starch to make up the deficiency of secondary stock performance, and wherein straw and starch are all
Belong to for health environment-friendly, short time reproducible resource, with low cost, recyclable again with.Take full advantage of natural resources.
3 are used in combination with existing paper making equipment, reduce the complexity of technique.
4, the material used is simple and environmentally-friendly, easy to process.The paper packing material intensity obtained and deflection are big, anti tear and
There is certain toughness, elasticity.
