The utility model discloses a full waste paper raw material is prepared from, has advantages such as low in production cost, the pop strength is high, good, the level and smooth degree of paper whiteness is high, printing adaptability is good.
Description
Technical field
The utility model belongs to field of papermaking, and in particular to a kind of white-top kraft liner board.
Background technology
White-top kraft liner board is usually used in making paper bag, sleeve for phonograph record, envelope, folder and sand paper etc..The life of white-top kraft liner board at present
Product technology is primarily present following point：(1) surface layer adopts bleached wood pulp, lining to use de- in the production of domestic top grade white-top kraft liner board
Ink slurry or blank sheet of paper side, core, bottom are not carried out the high-grade white-top kraft liner board of full waste paper production with domestic or imported waste paper, produce into
Height, and produce timber waste；(2) to there is strength character relatively low for the fine flour kraft inner paper major part of existing full waste paper production,
Cause carton compression performance not enough.In response to the requirement of national energy-saving consumption reduction, reduce the requirement of production cost and meet Gu
The use requirement of visitor, by improving the internal structure of fine flour kraft inner paper and the configuration of raw material, designs a kind of full waste paper
The performances such as the fine flour kraft inner paper of production, pop strength, paper whiteness and smoothness are good, meet the theory of environmental protection, are also
A kind of development trend.
Utility model content
For deficiency of the prior art, the utility model provides a kind of white-top kraft liner board, is prepared using full wastepaper as raw material
Form, have the advantages that low production cost, pop strength are high, paper whiteness is good, smoothness is high, printing adaptability good.
The utility model is achieved through the following technical solutions：A kind of white-top kraft liner board, is applied by surface layer, sandwich layer, bottom, front
Glue-line and back side glue application layer are constituted, and the surface layer, sandwich layer, bottom are sequentially compounding, and the surface layer is the shaping of MOW Deinking Pulps
Layer, sandwich layer is DIP Deinking Pulp shape layers, and bottom is OCC secondary stocks long fibre and OCC secondary stock chopped fiber mixed-forming layers, institute
State OCC secondary stocks long fibre and OCC secondary stocks chopped fiber replaces ordered arrangement, the front glue application layer is arranged on surface layer upper table
Face, the back side glue application layer is arranged on bottom lower surface, and each layer forms integrated white-top kraft liner board by hard calender press polish, leads to
Cross and improve original white-top kraft liner board layer structure and raw material layer, by original bottom OCC secondary stocks length or chopped fiber curling, winding
Irregular frame mode Deng nature stacking is improved to long and short fiber and unfolds uphold and alternately orderly arrangement mode, can improve
Pop strength, folding strength and smoothness into paper.
Preferably, the long stapled length of the OCC secondary stocks is 1～5mm, and the length of the OCC secondary stocks chopped fiber is
0.2～1mm.
Preferably, the weight in wet base of the surface layer, sandwich layer and bottom is respectively 20～30g/m2, 20～30g/m2, 60～160g/
m2。
Preferably, the glue-spread of the front glue application layer and back side glue application layer is respectively 1.5g/m2～3g/m2。
Preferably, the white-top kraft liner board burst index >=2.0Kpam2/g。
Preferably, the whiteness of the white-top kraft liner board is 75-85%.
Compared with prior art, the utility model has the advantages that：Slurrying adopts full wastepaper as raw material, belongs to environmental protection
Type packaging material, by reasonable disposition raw materials for production, and the layer structure to white-top kraft liner board is rationally arranged, and is made full use of
The waste paper pulp fiber of varying strength performance, can reduce the cost of raw materials for production, and it is equal to make into every critical index of paper
Meet coated manila national standard.
Description of the drawings
Fig. 1 is the structural representation of the utility model white-top kraft liner board.
Specific embodiment
Below in conjunction with the accompanying drawings with specific embodiment, the utility model is described further.
As shown in figure 1, the white-top kraft liner board in the present embodiment, by surface layer 2, sandwich layer 3, bottom 4, front glue application layer 1 and the back of the body
Face glue application layer 5 is constituted, wherein, surface layer 2, sandwich layer 3, bottom 4 are sequentially compounding, surface layer 2 be MOW Deinking Pulp shape layers, sandwich layer 3
For DIP Deinking Pulp shape layers, bottom 4 is OCC secondary stocks long fibre and OCC secondary stock chopped fiber mixed-forming layers, OCC secondary stocks
Long fibre and OCC secondary stock chopped fibers are unfolded and are upheld and alternately ordered arrangement, and each layer is through OCC pulping systems and MOW and DIP
Deinking bleaching system, by the size degradation of raw material, screening purification, bleaching flotation, then carries out heat partition hot-melt object process, and mill is beaten
Slurry, wherein the road flotation twice of MOW bleached pulps Jing tri- for surface layer are bleached；Sandwich layer DIP bleached pulp Jing twice flotation twice are bleached,
Bottom isolates long fine or short fibre and carries out alternately mixing in order by OCC pulping systems, quantitative with white-top kraft liner board in the present embodiment
For 125g/m2As a example by, the weight in wet base of surface layer, sandwich layer and bottom is respectively 24～28g/m2, 26～30g/m2, 68～73g/m2, front
The glue-spread of glue application layer and back side glue application layer is respectively 2g/m2Left and right；Each layer adds respectively chemical industry medicine, such as drying strengthening agent, dyestuff
