Abstract
The invention provides a manufacturing method of a cationic starch modified calcium carbonate filler. The manufacturing method comprises the following step: (1) gelatinizing cationic starch at the concentration of 2.5 percent; (2) diluting a calcium carbonate filler to the concentration of 70 percent; (3) sequentially extracting the gelatinized cationic starch and the calcium carbonate filler into a modification tank which is unceasingly stirred at the speed of 30-45r/min; (4) conducting reaction for about 20-30 min; and (5) placing the modified calcium carbonate filler into a storage tank for later use. The manufacturing method has the advantages of increasing the paper strength, improving the printing performance, lowering the consumption of wood pulp and reducing the manufacturing cost.
Description
Technical field
The invention belongs to the paper technology method, especially a kind of cationic starch modified calcium carbonate is made the manufacture method of filler.
Background technology
Paper grade (stock) cationic starch and pearl filler are added on respectively in the paper pulp, and cationic starch adds to after gelatinization in the slurrying workshop section with slurry pond, and paper is played enhancement; Pearl filler is added on machine hand's section starching pipeline, contains the filler paper printing performance and strengthens, and the oil suction performance of ink is good, and filler can reduce production costs simultaneously, and two kinds of chemical of prior art add respectively different workshop sections to, play different effects.
Summary of the invention
The present invention is in order to overcome the deficiencies in the prior art, and provides a kind of cationic starch modified calcium carbonate to make the manufacture method of filler.1., by 2.5% concentration gelatinization cationic starch technical scheme of the present invention is: the cationic starch modified calcium carbonate is made the manufacture method of filler; 2., dilution pearl filler concentration is 70%; 3., the cationic starch that gelatinization is good, pearl filler are carried in turn into the continuous stirring (modified tank of stirring velocity 30-45r/min); 4., the about 20--30min of reaction; 5. it is for subsequent use the pearl filler after the modification to be squeezed into hold-up vessel.
The invention has the beneficial effects as follows: add at double gummed paper by the pearl filler after the cationic starch modification, 350 kilograms of modified fillers of ton paper, become the paper folding endurance to bring up to 15--20 time by former 10 times and improved 50-100%, page two sides difference is carried and is reduced to 50%, retention has all improved 3--5%, fracture length has improved 10%, wood pulp uses 5% less, softwood pulp has used 5-10% less in the identical situation of paper strength, comprehensive cost has descended 85 yuan, is about 6,300,000 yuan of the Nian Chuanxiao of company.
Description of drawings
Fig. 1 is process flow sheet of the present invention.
Embodiment
Below in conjunction with Fig. 1 the present invention is described in detail.
1., by 2.5% concentration gelatinization cationic starch the cationic starch modified calcium carbonate is made the manufacture method of filler; 2., dilution pearl filler concentration is 70%; 3., the cationic starch that gelatinization is good, pearl filler are carried in turn into the continuous stirring (modified tank of stirring velocity 30-45r/min); 4., the about 20--30min of reaction; 5. it is for subsequent use the pearl filler after the modification to be squeezed into hold-up vessel.
Claims (1)
