If the day for announcing is the processing method that the Chinese patent CN103114490B on July 8th, 2015 discloses a kind of fiber reinforced composite corrugated board, fiber is compressed on facial tissue in the mode of wire rod or grid, above moulds adhesive for paper, then carry out compound with corrugated paper, carry out drying, cooling and shaping, so
After cut, impression, crosscut, pile, to obtain, cardboard bulk strength is high, the good product of mechanical property.But this technical scheme there is no actual humidification for the intensity of corrugated board integral surface.
Based on such scheme, make the present invention.
Summary of the invention
For solving the problems of the technologies described above and providing that a kind of facial tissue overall construction intensity is higher, the preparation method of the highly intensified corrugated paper of more environmental protection.
For solving the problems of the technologies described above, the preparation method of a kind of highly intensified corrugated paper provided by the invention, comprises the following steps:
(1) choose plant material and waste paper, add water and carry out bubble slurry, drop in pulper and pulverize, make raw material dissociate into fiber, and carry out filtering screening removal crude fibre and impurity, making beating, obtained magma, described magma beating degree is 35-45 ° of SR;
(2) get magma 80-120 weight portion obtained in step (1), add the vinal of 5-15 weight portion and the silica of 1-5 weight portion, fully mix;
(3) in the mixture in step (2), add cationic rosin size and wet strength agent, fully stir, then remove moisture, obtain the copy paper slurry that moisture content is 10-20%;
(4) copy paper slurry is carried out by paper machine obtained paper of manufacturing paper with pulp, top sizing is carried out to paper, through squeezing, dry and batch, obtain corrugated paper.
Further improvement is: the bubble slurry temperature in step (1) is 55-120 DEG C, and the bubble slurry time is 40-150 minute.
Further improvement is: described plant material be in wood leftover material, agricultural crop straw any one or two or more with arbitrarily than mixing mixture.
Further improvement is: described in step (2), wet strength agent is polyamide-based wet strength agent, and addition is 10-20 weight portion, and described cationic rosin size addition is 15-25 weight portion.
Further improvement is: adopt starch based sizing agent and reinforcing agent in step (4), degree of sizing controls at 0.5-0.75mm.
By adopting above-mentioned technical scheme, the invention has the beneficial effects as follows: the present invention adopts plant material and waste scrap carton as products material, this plant material can select the wooden and non-woods such as such as sawdust, wood chip, wood shavings, wood leftover material, agricultural crop straw, effectively utilize the discarded object that every profession and trade produces, recycle domestic waste scrap carton, the energy-conserving and environment-protective that the adaptation whole society advocates and recycling economy spirit simultaneously; Get the magma 80-120 weight portion obtained by plant material and waste paper, add the vinal of 5-15 weight portion and the silica of 1-5 weight portion, fully mix, by add polyvinyl alcohol and with a small amount of silica, use cationic rosin size and wet strength agent simultaneously, increase institute and produce moisture resistance and the physical strength of corrugated board, the consolidation sense of raising cardboard entirety and surface nature; Adopt starch based sizing agent and reinforcing agent, degree of sizing control 0.5-0.75mm, improve paper density and horizontal ring crush index, strengthen its DIMENSIONAL STABILITY, the properties of the corrugated paper adopting production method of the present invention to obtain and material index meet the requirements of corrugated paper completely simultaneously.
