Abstract
The present invention discloses high-strength corrugated core paper prepared by coating a melted jelly on the surface of a common corrugated core sheet, wherein the melted jelly is prepared by raw materials of peanut shells, hectorite and a cooking auxiliary agent. Compared to the prior art, the high-strength corrugated core paper disclosed by the invention has the following advantages: by improving the softening degree of fiber in the peanut shells, the effective jelly is obtained under a certain condition in coordination with hectorite, and is coated on the surface of base paper, and therefore a tensioning force of the core paper is improved, and the high-strength corrugated core paper is not prone to cracking when a corrugating machine is operated at a high speed, and the core paper has stronger ring-crush strength in the condition of a same thickness, and a stronger water shielding property and good binding adaptability.
Description
Technical field
The invention belongs to paper packaging box field of material technology, be specifically related to a kind of corrugating medium of high strength.
Background technology
Corrugating medium is mainly used as the corrugation sandwich layer of corrugated board, plays an important role to the shockproof properties of corrugated board.Also the package paper of breakables can be used alone as.It is processed through Corrugating Machine, forms corrugated paper by the Corrugator roller being heated to 160 ~ 180 DEG C by stupefied core paper.Usually, corrugating medium's fibr tissue is even, and paper web thickness is consistent, and bright yellow color, has certain bulk, has higher deflection, ring crush intensity and water imbibition, excellent laminating adaptability.But current technology increases its intensity by the thickness increasing corrugating medium usually, but the too thick meeting of corrugating medium makes the production of corrugated paper and use be restricted, stretching force when core paper rises stupefied by Corrugator roller simultaneously also can be affected.
Summary of the invention
The object of the invention is to improve corrugating medium's intensity for because increasing core paper thickness, and affect corrugation producing shaped problem, provide a kind of corrugating medium of high strength.
The present invention is achieved by the following technical solutions: a kind of corrugating medium of high strength, and in common corrugating medium, surface application dissolves jelly, described in dissolve jelly with peanut shell, hectorite, digesting assistant is that raw material is made.
As further improvement of these options, described in dissolve each raw material weight component of jelly and be: peanut shell 55-65 part, hectorite 28-32 part, digesting assistant 3-9 part.
As further improvement of these options, the described preparation method dissolving jelly is: add digesting assistant after being pulverized by peanut shell, maintain the temperature at 90-100 DEG C of boiling 2-4 hour, in gained slurries, add hectorite, stir under the condition of 60-80 DEG C and obtain jelly.
As further improvement of these options, described digesting assistant is any one or a few the mixture in anthrahydroquinone, dithianon, dihydro dihydroxy anthraquinone, tetrahydro-anthraquinone, 2-hydroxy-anthraquione, sodium anthraquinone sulfonate.
As further improvement of these options, described corrugating medium is one or more layers combining structure, and every layer of core paper surface is all coated with and dissolves jelly.
As further improvement of these options, described in dissolve when to become liquid colloidal thing when jelly is heated to 260-280 DEG C and apply, coating amount is 20-40g/m2.
The crude fibre of 60% is contained nearly in peanut shell, in peanut shell nutritional labeling, dry accounts for 90.3%, wherein thick protein 4.8% ~ 7.2%, crude fat 1% ~ 1.1%, crude fibre 65.7% ~ 79.3%, hemicellulose 10.1%, soluble-carbohydrate is 10.6% ~ 21.2%, peanut shell is also containing vitamin and mineral matter and partial amino-acid in addition, but current use amount is less, causes certain wasting of resources.Peanut shell, by carrying out boiling under the effect of digesting assistant, can improve the softening degree of fiber in peanut shell, protect its carbohydrate, the whiteness of its gained slurries and intensity are increased.
The present invention has the following advantages compared to existing technology: by improving the softening degree of fiber in peanut shell, coordinate hectorite to obtain effective mucilage binding thing under certain condition and be coated in body paper surface, improve the stretching force of core paper, not easily brisement is there is when Corrugating Machine runs up, when condition of equivalent thickness, there is stronger ring crush intensity, and having stronger water-resisting property, laminating adaptability is good.
Detailed description of the invention
Embodiment
2 parts of dithianons are added after being pulverized by 60 parts of peanut shells, 2 parts of hydroxy-anthraquiones and 4 parts of sodium anthraquinone sulfonates, maintain the temperature at 90-100 DEG C of boiling 4 hours, then in gained slurries, 32 parts of hectorites are added, stir under the condition of 60-80 DEG C and obtain jelly, be coated in corrugating medium surface after jelly being heated to 260-280 DEG C, after corrugating medium two sides being applied respectively jelly, pressing forms combining structure.
Corrugating medium's wet end furnish is that 80% state is useless and 20% Europe is useless, corrugation machine speed is 120-140m/min, in an experiment, common corrugating medium is experiment 1 group, the jelly coating amount of experiment 2-4 group is respectively 20g/m2,30g/m2 and 40g/m2, detect its tensile index respectively, tear index and water absorption rate, to draw after data preparation as shown in following table:
| Project | Glue-spread g/m2 | Tensile index N*m/g | Tear index mN*m2/g | Hygroscopicity value g/m2 |
| Test 1 group | Nothing | 45.8 | 8.52 | 32 |
| Test 2 groups | 20 | 51.6 | 8.83 | 25 |
| Test 3 groups | 30 | 54.9 | 8.86 | 23 |
| Test 4 groups | 40 | 55.3 | 8.87 | 22 |
Table 1
Data as can be seen from table 1, in corrugating medium surface application the present invention after jelly, stretching force and anti-fracture ability increase all to some extent, and increase to a certain degree can be had along with the increase of coating amount, simultaneously, hygroscopicity value under the same terms has obvious reduction, and illustrate that this corrugating medium's water-resisting property is good, intensity is higher.
