Description
Technical field
The invention belongs to pulp technology for making paper, relate to a kind of preparation method of the modified grammite for papermaking filler.
Background technology
In paper-making process, add filler can reduce production cost, increase the optical property such as whiteness, opaqueness of paper, improve dimensional stability properties, improve the printing adaptability of paper simultaneously, but add to fill out also can be with and serve negative effect, such as, reduce paper strength.For general filler, if paper-making process does not use Retention Aid System or improper use, filler is kept more difficult in paper.Wollastonite is a kind of novel papermaking filler developed in recent years, and it is a kind of three oblique chain calcium metasilicate mineral, and molecular formula is CaSiO

32% ~ 5%, MgO2% ~ 5%, in white or canescence, vitreous luster to pearliness, density 2.78 ~ 2.91g/cm
3, hardness 4.5 ~ 5.0, fusing point 1544 DEG C, has good thermostability and chemical stability.Particle is needle-like or threadiness, and production technique is different, and length-to-diameter ratio is different, and usual length-to-diameter ratio is (7 ~ 8): 1, and what have reaches (15 ~ 20): 1.Due to the fibrous profile of wollastonite, attract the attention of many papermaking researchists and enterprise, and carried out series of studies.Research shows, wollastonite as functional stuffing Some substitute paper pulp fiber, can reduce production cost; Different from traditional papermaking filler, add a certain amount of fibrous wollastonite, little on paper strength impact; The retention of wollastonite is higher than conventional filler, can reach 70% ~ 80%.But, there is two problems in wollastonite: (1) wollastonite can show the trend along the fragmentation of cleavage surface cleavage in graded crushing process in actual application, wollastonite powder body is made to form sharp-pointed corner angle, wollastonite packing hardness is higher, granularity is larger, wearing and tearing can be produced to web part of paper machine (forming net and dewatering elements) in paper-making process, reduce its work-ing life; (2) because the density of wollastonite is higher than fiber, when adding the amount of filling out and being higher, if page quantification is constant, along with the increase of amount of filler, the bulk of page reduces.
In order to improve the effect of wollastonite as papermaking filler further, solve produced problem in application, carrying out modification to wollastonite is a kind of thinking.CN102249530A discloses a kind of method of the dry method modification wollastonite utilizing the superpolymer of positively charged ion amides in wollastonite crushing process, and what increase wollastonite adds the amount of filling out, and improves the printing of opening and an optical property.CN103031761A discloses the method utilizing the composite modified paper grade (stock) wollastonite of multi-chemical, first in crushing process, modifier A is added, then add water after making wollastonite pulping, add properties-correcting agent B and C successively again, to improve filler retention further, thus the wearing and tearing reduced paper machine equipment, improve the addition of filler.CN102745909A discloses a kind of preparation method of low abrasion wollastonite packing, mainly when filler pulping at the polymer substance of the easy film forming of Surface coating one deck.The thinking of these methods is all at the surface adsorption of wollastonite particle or coated one deck cationic substance, improves the retention in paper-making process.But, the dry method modification of properties-correcting agent is added in the crushing process of wollastonite, although simple to operate, but facts have proved and can not solve produced problem in wollastonite use procedure completely, wet-process modified production cost, the carrying cost increase causing filler manufacturer, or paper mill investment increases, complex operation, and these methods are all carry out modified silicon ash hardcore by adding other chemical in addition, the problem brought may disturb the charge balance of wet end of machine, does not reach the effect of anticipation.
Summary of the invention
The object of the present invention is to provide a kind of modified grammite preparation method, utilize modified grammite that this preparation method obtains as papermaking filler, improve the whiteness of page, bulk wearing and tearing to paper machine dewatering elements when reducing copy paper.
The technical scheme that the present invention realizes object is as follows:
For a preparation method for the modified grammite of papermaking filler, concrete grammar is as follows:
(1) unmodified wollastonite powder is put into water, be uniformly mixed, obtain the wollastonite powder liquid suspension that mass concentration is 1-35%, the temperature of suspension is risen to 20-99 DEG C;
(2) add the 0.01-1.50mol/L phosphate solution of the 0.1-12% of wollastonite weight, be uniformly mixed, be that 5-98% inorganic acid solution is added in wollastonite powder liquid suspension by concentration, mineral acid consumption is the 1-50% of wollastonite weight, when then continuing stirring reaction to pH value >=5.5, reaction stops;
(3) continuing in aforesaid reaction system, add mass concentration is 0.1-55% inorganic base substance, and adjust ph, to 6.5-9.5, stops stirring after reaction 5-90min, leaves standstill cooling and stablizes to make modified grammite be able to ageing;
(4) reaction product step (3) obtained carries out filtering and drying, namely obtains the wollastonite of modification.
And described phosphoric acid salt is the mixture of a kind of in tripoly phosphate sodium STPP, Sodium hexametaphosphate 99, sodium phosphate, sodium polyphosphate or trisodium phosphate or at least two kinds.
And described mineral acid is the mixture of a kind of in sulfuric acid, hydrochloric acid, nitric acid or phosphoric acid or at least two kinds.
And described inorganic base substance is the mixture of a kind of in sodium hydroxide, sodium carbonate, sodium bicarbonate, calcium hydroxide, calcium oxide, hydrated barta, barium oxide and water glass or at least two kinds.
And described unmodified wollastonite powder selects the unmodified wollastonite powder of flat equal grain footpath≤50 μm.
The advantage that the present invention obtains and beneficial effect are:
1, the present invention take wollastonite as raw material, filler chemical constitution, particle surface situation etc. are changed by inorganic polymer composite flocculant, achieve and the particle of wollastonite powder is reconstructed, on the threadiness had at wollastonite powder granular raw or the basis of acicular morphology, the loose porous material of Surface coating one deck, while the original characteristic of maintenance, whiteness improves, wearing and tearing and tap density decline, added by fill out the page characteristic of manufacturing paper with pulp good.
2, the Wollastonite modified method that the present invention relates to has the advantages such as technique is simple, modified chemical medicine is cheap and easy to get, investment of production equipment is little, with the wollastonite packing prepared by the present invention, inherit the advantage of unmodified wollastonite, overcome original shortcoming, the page manufactured paper with pulp has good physical strength, optical property, printing adaptability and appearance property, extend the life-span of forming net, reduce paper production cost, there is bright prospects for commercial application.
