Abstract
The invention discloses a preparation method for high-intensity corrugated paper, and relates to the technical field of papermaking. The preparation method comprises the steps: respectively weighing wood pulp and waste paper pulp, uniformly mixing the pulps, removing impurities, adding water to soak the pulps, transferring the pulp into a disperser for dispersion to obtain primary pulp, adding a polyacrylamide solution, performing papermaking to prepare paper, preheating the paper, applying glue, putting the paper into single jersey machine to obtain corrugated paper, and transferring the corrugated paper into a drying oven for drying. The high-intensity corrugated paper disclosed by the invention is mainly prepared by the wood pulp prepared by wood leftovers and the waste paper pulp, so that raw materials are readily available, wastes are turned into treasures, and the production cost is lower; in a papermaking process, polyacrylamide is added, so that the bursting index and the ring crush index of the corrugated paper are greatly increased; therefore, the corrugated paper is higher in intensity, and the service life of a corrugated carton is prolonged.
Description
Technical field
The present invention relates to pulp technology for making paper, especially a kind of preparation method of highly intensified corrugated paper.
Background technology
Corrugated paper is a kind of general package paper, because of its have rational in infrastructure, processing is simple, quality is light, cost is low and be convenient to store and the advantage such as transport, become paper container package the most widely, be widely used in transportation and packing field.Corrugated paper is the plate object be bonded by sheet lining and the corrugated paper of waveform being processed by corrugated roller and formed, is generally divided into single wall corrugated board and double-layer corrugated cardboard two class.
Along with the extensive use of corrugated case, the quality requirement of packaging industry to corrugated paper is also more and more higher: require that corrugated paper possesses strong burst index and ring crush index, and its burst index of existing corrugated paper and ring crush index all more weak, cause corrugated case pack or transportation in very easily rot.
Summary of the invention
The object of this invention is to provide a kind of preparation method of highly intensified corrugated paper, this highly intensified corrugated paper can solve burst index and the lower problem of ring crush index.
In order to solve the problem, the technical solution used in the present invention is:
Highly intensified corrugated paper of the present invention, its preparation method comprises the following steps:
A, take wood pulp and secondary stock respectively, mix, removing impurity, add water and carry out bubble and starch, then proceed to disperser slurry is broken up, obtain magma;
B, in described magma, add polyacrylamide solution, copy paper obtains paper;
C, by described paper preheating, adopt sizing applicator by adhesive uniform application at paper surface, cross single-side machine obtain corrugated paper;
D, proceed to baking oven and carry out drying.
In technique scheme, scheme can also be more specifically: described in step A, wood pulp is prepared from by wood leftover material.
Further, the mass ratio of wood pulp described in step A and secondary stock is 1:1.5 ~ 3.
Further, the temperature 40 DEG C ~ 50 DEG C of water in step A, the bubble slurry time is 10 minutes ~ 15 minutes.
Further, in step B, the concentration of polyacrylamide is 3 mol/L ~ 5 mol/L, and the mass ratio of described polyacrylamide and described magma is 1:4 ~ 10.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
The wood pulp that highly intensified corrugated paper of the present invention is prepared into primarily of timber waste and secondary stock are prepared from, raw material sources are extensive, turn waste into wealth, production cost is lower, polyacrylamide is with the addition of in paper-making process, greatly strengthen burst index and the ring crush index of corrugated paper, make this corrugated paper possess higher intensity, improve the service life of corrugated case.
