Description
Technical field
The invention belongs to papermaking chemical product production field is and in particular to a kind of preparation method of corrugated paper Cypres
With the product obtained by this preparation method, and the application of this product.
Background technology
At present, corrugated board obtained for various commodity make packaging and comprehensively popularize, promotion and application.By
In the packing container made using corrugated board to beautification and protect built-in commodity have its unique performance and advantage, its with many
Obtain great success in the competition of kind of packaging material, become and grow so far with not waning and assuming the making bag of fast development
One of main material of packaging container.
Corrugated board generally by facial tissue, inner paper, core paper and is processed into the corrugated paper of waveform Concha Arcae by being bonded.According to
The demand of commodity packaging, corrugated board can be processed into single face corrugated board, triple wall board, five layers, seven layers, eleventh floor etc.
Corrugated board.Wherein, single face corrugated board be typically used as commodity packaging stickers lining protective layer or make light card lattice, backing plate with
Protect vibrations in the transportation of storage for the commodity or collision, three layers the most normal in making corrugated case with five-layers corrugated fiberboard
With.
The packaging of many commodity carries out the simply packaging of fineness by three layers or five-layers corrugated fiberboard, in corrugated case or
Beautiful colorful figure and picture are printed in the surface of corrugated paper box, and this not only protects the commodity of inherence, and to packaging
Commodity serve publicity and beautification function.And seven layers or eleventh floor corrugated board be mainly used as electromechanics, flue-cured tobacco, furniture, motorcycle,
White goods etc. make packing cratess；In specific commodity, inside and outside casing can be made with the combination of this corrugated board, be easy to

The commodity packaging that plate makes, has the trend gradually replacing wooden-box package.
At present, the production of corrugated paper or corrugated board and preparation technology persistently improve, gradually from high grammes per square metre to
Low grammes per square metre direction is developed；And preferentially adopt waste paper to replace wood pulp although the paper strength of such gained is poor and hygroscopicity value is high；
Further, since there is the problem that more the led to paper quality of internal sizing variable factor is unstable, class is difficult to raising,
Most of manufacturer less with or abandon internal sizing, then the technique being made up using top sizing become popular become
Gesture.
For above-mentioned top sizing process, correspondingly sizing agent is had claimed below in production technology: a) effectively carry
High ring-pressure strength；B) significantly reduce cobb value (hygroscopicity value)；C) ripening speed is soon it is desirable to lower machine is just ripe.However, it is existing on the market
Though some overwhelming majority Cypres can improve the ring crush intensity of corrugated paper to a certain extent, often there is sizing agent
The consumption problem of high cost greatly.
In the prior art, for example disclosed in Chinese patent cn102660899a a kind of sizing agent although ripening speed is fast,
And do not get damp, but be the failure to significantly improve the ring crush intensity of corrugated paper.
Therefore, develop a kind of ring crush intensity that can either effectively improve corrugated paper, and significantly reduce cobb value, can again
Ensure ripening fireballing corrugated paper Cypres, be one of emphasis of the current research and development of those skilled in the art.

Temperature to 40 DEG C, then be separately added into sizing agent that comparative example and embodiment 1～4 be obtained (Oxytarch (is done): sizing agent (wet)=50:
4), add water and be diluted to 8wt%.
Then, respectively by each glue application solution of the sizing agent being obtained containing comparative example and embodiment 1～4 in 120g fluting medium
On be coated with 10# spreading rod, coating weight be 2g/m2, dry 30 seconds or 120 seconds in 110 DEG C of baking ovens respectively after coating, take
Go out, be cooled to room temperature, and carry out following detection:
Cobb value measures:
Xsh type using Hangzhou Qingtong Boke Automation Technology Co., Ltd. suddenly can press gb/t 1540-1989 by absorbability analyzer
Method detects pattern to be measured.
Ring crush intensity measures:
Ct300a compressive strength tester using Hangzhou Qingtong Boke Automation Technology Co., Ltd. detects pattern to be measured.
Concrete testing result see table 1, and wherein, cobb value is more low, shows that hygroscopicity value is lower, ring crush index gets over Gao Zebiao
Bright intensity is bigger:
Further, above-mentioned test pattern is placed under 95% damp condition 24 hours and is surveyed with same method by inventor
Cobb value and ring crush intensity, testing result is as shown in table 2 below:
By the data in Tables 1 and 2, the sizing agent being obtained using the embodiment of the present invention 1 ~ 4 compared with comparative example, not only
Can rapid aging, increase substantially the ring crush intensity of corrugated paper, cobb value be greatly reduced, and, in wet condition, cobb
Value value added is less, and ring crush intensity decreasing value is also less, and this shows that Cypres provided by the present invention have very strong resisting
Get damp performance.
Above the specific embodiment of the present invention is described in detail, but it has been intended only as example, the present invention has not limited
It is formed on particular embodiments described above.To those skilled in the art, any equivalent modifications that the present invention is carried out and
Substitute also all among scope of the invention.Therefore, the impartial conversion made without departing from the spirit and scope of the invention and
Modification, all should cover within the scope of the invention.
