Background technique
By the development of " 12th Five-Year Plan " planning period paper industry, paper industry generally increases the recycling of waste paper and utilizes power
Degree, especially boxboard manufacturer use reclaimed waste paper or be primary raw material using reclaimed waste paper are development main trend.Ox-hide boxboard
Paper is also known as kraft inner paper or face hangs cardboard.There are brown kraft paper boxboard, point of light Kraft carton paperboard.It is than general case paper
Plate is more tough and tensile, sturdy, there is high compression strength, resistance to Punctured Strength and folding strength, has that humidity resistance is good, presentation quality is good
The features such as, mainly for the manufacture of foreign trade packing carton and domestic high-grade goods Packaging Box.Kraft liner board is that transportation and packing are used
Advanced cardboard.It is more more tough and tensile than general boxboard, sturdy, there is high compression strength, resistance to Punctured Strength and folding strength, tool
There is the features such as humidity resistance is good, presentation quality is good, mainly for the manufacture of foreign trade packing carton and domestic high-grade goods Packaging Box.
The manufacture craft of existing kraft paperboard, environmentally friendly degree is inadequate, while the kraft paperboard folding strength, resistance to broken made
Degree and oxygen index (OI) are lower, and water-resistance, antioxygenic property are lower, and it is small to be applicable in prospect.
Summary of the invention
The purpose of the present invention is to provide a kind of manufacturing methods of novel environment friendly kraft paperboard, to solve above-mentioned background skill
The problem of being proposed in art.
To achieve the above object, the invention provides the following technical scheme:
As a further solution of the present invention: the slurry the production method is as follows: collect waste and old unused crate, use scattered slurry
Machine carries out size degradation to crate；Water and biomembrane are added after size degradation, is persistently stirred at a temperature of 40 degree, slurry is made, then use
Screen slot is that the sieve plate of 0.5mm is filtered, and removes coarse impurity；Be classified after filtering using classifying screen, obtain long fine slurry,
Middle fine slurry and three kinds of waste paper pulps of fluff pulp, are then rationally beaten, in the part that waste paper pulp is classified out it is fine starch with it is short
Fibre slurry mixing is used as surface layer slurry, and fine slurry is used as sandwich layer in residue, and long fine slurry is bottom；The crate used is waste and old do not have to
, it solves and is effectively saved resource, while avoiding waste, certain effect is played to environmental protection.
As a further solution of the present invention: it is fire retardant, desiccant, polyvinyl alcohol and alginate that the table, which applies auxiliary agent,
Combination；Weight ratio is 2:1:3:2.
As a further solution of the present invention: a kind of manufacturing method of novel environment friendly kraft paperboard includes the following steps
And technique:
S1 is added slurry into paper machine stock tank, then by grinding calcium carbonate, fungicide, wet strength agent, and dispersing agent is added paper machine stock tank and holds
Continuous stirring, while keeping temperature in 50 degree, mixing time 20min；Wherein aluminium hydroxide is to be filled with mode to be added in slurry；
S2, brightening agent is added in the product that S1 is obtained, while persistently stirring 1h；
The product of S2 is added table and applies auxiliary agent, is diluted with water by S3, by being arrived by double-layer headbox tiling during stirring
It is filtered on forming net, the aperture of forming net is 0.05mm, and fiber forms filter cake on net, aspirates by vacuum tank, is obtained
L Water Paper page；
The product obtained in S3 is used rod press dewatering, reuses dryer and dried by S4；
Press polish: the page obtained in S4 is sent into calender press polish to get boxboard page of the present invention by S5.
Compared with prior art, the beneficial effects of the present invention are: step of the present invention is simple, sufficiently using discarded cardboard
Case plays the role of protecting environment, while surface covering can increase the water-resistance of the kraft paperboard, inoxidizability, simultaneously
Compared to existing kraft paperboard, the kraft paperboard which manufactures has preferable folding strength and bursting strength, meets
Practical application has application prospect well.
