Description
Technical field
The present invention relates to the field of comprehensive utilization of papermaking waste more particularly to papermaking waste in corrugated paper and boxboard
Application in top sizing.
Background technique
At this stage, people are higher and higher to wrapping paper quality requirements, and as the most tight environmentally friendly storm of country, waste paper importation limit
Under the influence of a series of policies such as system order, corrugated paper and boxboard production cost are greatly improved, and how to solve this predicament, are perplexed
Major papermaking enterprise.
Numerous producers are to improve paper quality, and the intensity of paper product is mainly improved by surface sizing techniques, is generallyd use
A large amount of starch is added, the method for carrying out top sizing.But due to the rapid rise of price of starch, starch dosage is bigger, and cost is higher,
And intensity increase rate is limited, thus the increase of production cost is caused, enterprise profit reduces.
The pulp washing liquid after boiling is washed in paper industry, during sulfate process or soda pulping, is commonly referred to as
Black liquid, component include many kinds of substance such as cellulose, hemicellulose, natural polyphenol, monosaccharide, polysaccharide, oligomer.But
In paper-making process, due to no practical function, and it is considered as waste, has not only increased the pressure of subsequent environments improvement, but also causes
The waste of resource.
Summary of the invention
The present invention is intended to provide a kind of papermaking waste and preparation method thereof and the papermaking waste are in corrugated paper and case
Application in paperboard top sizing, to solve drawbacks described above existing for background technique.
The present invention realizes by the following technical solutions:
A kind of preparation method of papermaking waste includes the following steps: to mix black liquid with strong alkali aqueous solution, 70-
It is sufficiently reacted under the conditions of 90 DEG C, acid is then added and adjusts its pH to 3-4, the papermaking waste is obtained after removal of impurities.
The black liquid washs the pulp washing liquid after boiling during referring to sulfate process or soda pulping.
Preferably, the solid content of the black liquid is 10-30wt%.
Preferably, the highly basic is selected from at least one of sodium hydroxide or potassium hydroxide, from a cost perspective, preferably
Select industrial lye.
Preferably, the additional amount of the highly basic is the 80-120wt% of the black liquid oven-dry weight.
Preferably, the acid is at least one of sulfuric acid or hydrochloric acid.
It is small that 2-3 is reacted after black liquid is mixed with strong alkali aqueous solution as a preferred technical solution, under the conditions of 70-90 DEG C
When, acid is then added and adjusts its pH to 3-4, the papermaking waste is obtained after the screen to filtrate cleans.Preferably, the sieve
Specification be not less than 200 mesh, preferably 325 mesh screens, to obtain better impurity-eliminating effect.Certainly, if selection aperture is smaller
Sieve, although can remove more tiny impurity, filter efficiency is slack-off.Those skilled in the art can be according to practical life
Production needs to select suitable impurity removal process.
The present invention also provides the papermaking waste being prepared using the above method, its component of the papermaking waste includes
At least one of cellulose, hemicellulose, natural polyphenol, monosaccharide, polysaccharide, oligomer.
The present invention furthermore provides application of the papermaking waste in corrugated paper and boxboard top sizing, described to make
The starch application of the alternative 5-100% of paper waste is in corrugated paper and the top sizing of boxboard.
The papermaking waste can be added in starch maturing process, can also surface sizing starch liquid after curing
Middle addition.
Preferably, the starch application of the alternative 20-80% of the papermaking waste is applied in the surface of corrugated paper and boxboard
Glue.
Papermaking waste of the present invention is applied to corrugated paper and boxboard top sizing in paper industry, can partially or completely replace
For size-press starch, while not influencing water resistant effect, the intensity of paper is improved, has not only realized the recycling of waste resource, but also
Top sizing cost is effectively reduced, application prospect is good.
Specific embodiment
The present invention is illustrated below by specific embodiment, but is not intended to limit the present invention.
Embodiment 1
The preparation of papermaking waste: by the solid content generated in sulfate pulping process be 20wt% black liquid with
32wt% industrial lye (effective component is sodium hydroxide) is mixed according to oven-dry weight 1:1, reacts 3 hours under the conditions of 70-90 DEG C, so
Sulfuric acid is added afterwards and adjusts its pH to 3.5 or so, obtains the papermaking waste after 325 mesh screen filtering and impurity removings, solid content is
15%.It include 65% or so cellulose, 30% or so hemicellulose in its component.
Embodiment 2
Shandong Large Box Plate Paper Factory enzyme turns cornstarch liquid, Cypres, is not glued corrugated paper body paper, using its watt
Stupefied paper surface sizing technique: starch: Cypres: aluminum sulfate (30%)=35:5:1 (dry/wet/wet) compares sizing.
Specific formula is shown in Table 1, and pattern physical performance index is shown in Table 2 after sizing.
The dry measures alternative techniques such as 1 new departure starch of table
| Original process | 100% starch |
| New process one | + 20% papermaking waste of 80% starch |
| New process two | + 40% papermaking waste of 60% starch |
| New process three | + 60% papermaking waste of 40% starch |
| New process four | + 80% papermaking waste of 20% starch |
Table 2 is glued pattern strength physical index (temperature: 23 DEG C of humidity: 50%)
20%, 40%, 60%, 80% original process are substituted using papermaking waste it can be seen from above-mentioned application result to apply
Amylopectin, can be improved the corrugated paper sizing ring crush index of pattern, bursting strength, folding strength, and to paper water resistant effect, form and aspect without
It influences.
Embodiment 3
In Shandong, large-scale papermaking enterprise boxboard paper machine tries out papermaking waste, respectively by 20%, 40%, 60%,
The dry measures such as 80% substitute original process surface sizing starch, investigate experiment front and back, are glued pattern water resistant effect and Strength Changes, verifying
