Description

A kind of high whiteness cigarette pack cast-coated paperboard of unstressed configuration and preparation method thereof

Technical field

The invention belongs to cigarette pack paperboard fields, and in particular to the cigarette of the unstressed configuration Gao Bai of coating method production Pack paperboard and preparation method thereof field.

Background technology

The paperboard for being used for cigarette packaging currently on the market is usually the unstressed configuration raw white coated white cardboard of 215-250g/ ㎡, For whiteness no more than 80% (generally in 75%-78%), eye sight whiteness is lower, and milky, Wu Faman is presented in printing product background color The requirement of the high whiteness of foot (whiteness is more than 83%) exquisite printing, also useful above-mentioned paperboard is processed into as base stock currently on the market For the method and product of cast-coated paperboard, but since this highlight coating is transparent material, product whiteness can not continue to improve.

Also the high white glass paperboard of useful unstressed configuration produces (whiteness is in 83%-85%) for cigarette packet on existing market, but should Product has the following problems, due to being to carry out unstressed configuration dyeing in paper pulp and coating in paper-making process to brighten if in paper Dyeing, which is brightened, in slurry is brightened form and aspect by PH difference slurry colorings and different slurry kind there are greatest differences.It cannot be simultaneously to paper pulp Middle difference slurry is brightened or the paper of multilayer difference pulp production carries out unstressed configuration and brightens, but the production of cigarette packet paperboard is adopted With three kinds or more different pulp varieties, at least four-layer structure produces.Therefore existing product can only be carried out uniformly with a kind of slurry It brightens, causes product to be deformed in printing process very big, printing difficulty is high, yield rate bottom 5- compared with normal cigarette card product 8%, deflection and the low 30-40% compared with quantitative similar cigarette card, upper cigarette packing machine packet cigarette molding effect is poor, low production efficiency, It is influenced by the pH value of slurry and coating, the factors such as content of beary metal when due to being brightened in paper pulp, the aberration of batch is larger, makes Product can not fully meet the requirement of cigarette packet paperboard.

In addition in the prior art, brighten in paper pulp or coating in unstressed configuration brighten there are coloring agent tinctorial yield is low, waste water In have a large amount of dye solutions, cause pulping wastewater treatment of high cost and PH of the tinctorial yield in by slurry, content of beary metal Influence causes to brighten unstable, larger difference occur, and this method improves under the premise of without fluorescent whitening agent Whiteness is only 3-5%.

Prior art, which also has, produces the high art post paperboard (85% or more) containing fluorescent whitening agent by coating waste water mode As cast-coated paperboard, to adapt to exquisite printing.But since the product uses fluorescent whitening agent to improve whiteness, it is not used to perfume (or spice) Cigarette packaging (cigarette packet paperboard requires to be forbidden to use fluorescent whitening agent).

The prior art also has the face layer whiteness that cigarette card is improved using one layer of titanium dioxide of coating, although and using rubbing method Whiteness is improved under the premise of without fluorescent whitening agent, but due to keeping the folding strength of paperboard big after being coated on original cigarette cardboard Width reduces, and occurs a large amount of quick-fried black phenomenons after causing product to print when packet cigarette, and cannot be used for cigarette packet.
