B, add straw pulp: in paper pulp, add a certain amount of straw pulp after pulping completes, wherein, the ratio of paper pulp and straw pulp is 1:1;
C, desanding defibrination: in high concentration desanding device, remove the impurity that mixed waste paper slurry internal ratio is great, then enter into low dense desander inner filtration and fall the tiny grains of sand and impurity, enter into after desanding in grinder and carry out grinding wherein, in high concentration desanding device, the desanding time is 0.5 hour, in low dense desander, the desanding time is 0.6 hour, and after grinding, beating degree is 43 degree;
D, interpolation dry strength agent: cationic starch and aqueous epoxy resins are added water and mixes, the ratio of cationic starch, aqueous epoxy resins and water is 1:1:6, then stir uniformly, slurries are made fully to stir rear retrogradation, and then in solution, add KPS oxidant, and by solution gelatinization half an hour under the high temperature of 90 DEG C, obtain dry strength agent, then dry strength agent is joined in slurries, maintain the temperature between 70 DEG C ~ 80 DEG C and carry out drying;
E, add sizing agent: the third ethene and acrylic acid are added to the water Homogeneous phase mixing, obtain sizing agent;
F, applying glue: then the body paper of non-applying glue is laid on horizontal coating machine, then by coating machine, sizing agent is applied in paper surface;
G, drying and processing: the paper after applying glue is put in press polish dryer and dries, obtain highly intensified corrugated paper.
Further, in step a, the content of the deinking agent added is 5 ~ 8kg ∕ T, and meanwhile, the revolution of high density hydraulic pulper is 2300r ∕ mim.
Further, in stepb, straw pulp passes through grinding and slurries mixed with water by stalk or wheat-straw, and wherein, the ratio of stalk or wheat-straw and water is 1:4.
Further, in steps d, Substance is 120g ∕ ㎡ ~ 135g ∕ ㎡, and degree of sizing is 3.5s, and ring crush intensity index is 5.34N ﹒ m ∕ g, and deflection is 21 ~ 25g ﹒ cm, and ph value is 5 ~ 6.
Further, in step e, the mass percent of the third ethene is 12%, and acrylic acid mass percent is 18%.
The invention has the beneficial effects as follows: this regeneration high-strength corrugated base paper and preparation technology thereof are by waste and old corrugated paper recycling, a lot of resource can be saved, cut the waste, and in production process, technique is simple, the corrugated paper properties produced is given prominence to, intensity height not cracky, and the paper mill being applicable to different scales produces.
