Abstract
The invention relates to high-strength paper pulp and a preparation method therefor. The high-strength paper pulp is prepared by the steps: by taking dibutyl phthalate, polypropylene fiber, zinc stearate, kaolin, Chinese alpine rush, bagasse and waste paper as raw materials, crushing the waste paper; cutting the Chinese alpine rush into slices; soaking the waste paper, the Chinese alpine rush and the bagasse together into a sodium hydrogen carbonate solution to be soaked; grinding the waste paper, the Chinese alpine rush and the bagasse into a high concentration grinder to be ground to obtain first slurry, wherein the gap between grinding discs is 0.25 mm; mixing the dibutyl phthalate, polypropylene fiber, zinc stearate and kaolin with the first slurry; keeping the temperature for 30-50 minutes at the steam pressure of 30.25*10<3>pa-31.17*10<3>pa to obtain a slurry mixture; and putting the slurry mixture into the high concentration grinder to be ground to obtain the high strength paper pulp. The high strength paper pulp provided by the invention is simple in preparation method and low in production cost. Waste resources are reasonably used, and the production energy consumption is low. The prepared paper is flat and smooth and the tensile strength can reach 4.0-4.1KN/m.
Description
Technical field
The invention belongs to packaging product field, particularly relate to a kind of strong pulp and preparation technology thereof.
Summary of the invention
Paper pulp take string as raw material, through the fibrous material that different processing methods is obtained.Mechanical pulp, chemical pulp and chemimechanical pulp can be divided into according to processing method; Also wood pulp, straw pulp, jute pulp, reed pulp, sugarcane slurry, bamboo pulp, rag stock etc. can be divided into according to fibrous raw material used.Refined pulp, bleached pulp, unbleached pulp, high-yield pulp, semi-chemical pulp etc. can be divided into again according to different purity.Generally be used for manufacturing paper and cardboard, current China timber resources far can not meet the needs of growing pulp and paper industry, in recent years, along with the raising of people's lives, also more and more higher to the requirement of strength of paper simultaneously.
Summary of the invention
The object of the present invention is to provide a kind of strong pulp and preparation technology thereof.
The invention provides a kind of strong pulp, described strong pulp raw material is formed and parts by weight are:
Dibutyl phthalate 7-9 part
Polypropylene fibre 2-5 part
Zinc stearate 0.3-1.0 part
Kaolin 3-5 part
Chinese alpine rush 20-22 part
Bagasse 40-45 part
Waste paper 30-35 part
Its preparation process is:
Pulverized by waste paper, shape of being cut into chunks by Chinese alpine rush, together puts into 3-5wt% sodium bicarbonate solution by waste paper and Chinese alpine rush, bagasse, at 98-100 DEG C, soaks 60-80 minute;
Waste paper, Chinese alpine rush, bagasse are put into high-concentration paste mill and ground to obtain the first slurry, and millstone gap is 0.25mm, and speed of grinding plate is 1520r/min;
Dibutyl phthalate, polypropylene fibre, zinc stearate, kaolin are mixed with the first slurry, 30.25 × 10
3pa-31.17 × 10
3be incubated 30-50 minute under the steam pressure of pa, obtain slurry mix;
Slurry mix is put into high-concentration paste mill and grind to obtain strong pulp of the present invention, millstone gap is 0.15mm, and speed of grinding plate is 1520r/min.
By strong pulp through upper net forming, squeeze to moisture lower than 35%, obtain manila paper through infrared drying, infrared wavelength is 2.5-2.6um, and bake out temperature is 60-65 DEG C, and drying time is 45-50 second.
Further, the waste paper used in the present invention is second-class waste paper.
Preparation method of the present invention is simple, production cost is low, Appropriate application waste resource, energy consumption is low, and raw material pulping performance is good, pulping yield is high, the pulp quality obtained is good, and fibrous binding force is high, and interpolation dibutyl phthalate, polypropylene fibre, zinc stearate, kaolin can improve pulp strength, obtained paper formation is smooth, and tensile strength can reach 4.0-4.1KN/m.
