Abstract
The invention relates to high-bulk paper manufactured by adopting chemical wood pulp and a manufacture method of the high-bulk paper. The high-bulk paper is mainly characterized in that the mass mixture ratio of the pulp of chemical needle-point leaf wood pulp to chemical broad leaf wood pulp is (15-30):(70-85), filling materials are silicate base high-bulk great-particle filling materials with the addition being 20 percent to 40 percent, the consumption of retention aid is 0.3 to 0.5kg/ton paper, and the consumption of cationic starch is 8 to 15kg/ton paper. Handsheets made by adopting the method have the characteristics that the bulk is high, the filling content is high, and the paper intensity retention is good.
Description
Technical field
The invention belongs to field of papermaking, be specifically related to a kind of method that adopts chemical wood pulp to make the high bulk paper.
Background technology
In recent years, the paper producer more and more pays close attention to this index of bulk of paper.Open because the high bulk paper can condition of equivalent thickness substitutes original heavu weights, not only practice thrift fibrous raw material, reduce production costs simultaneously and cost of transportation, thereby bring better economic benefit for enterprise.On the market, high bulk paper is called light paper again, and bulk is generally at 1.6g/m
3～1.9g/m
3Between, generally adopt the leaf wood chemi-mechanical pulp to join and copy with needlebush chemi-mechanical pulp or a spot of chemical pulp.High bulk paper has obtained market approval as medium-to-high grade books with the paper upgraded product with the high characteristics of its bulk.Therefore, high bulk light paper has good market prospects as medium-to-high grade books with paper.
Quantitatively being 80g/m
2Wood-free paper be example, usually the wood-free paper bulk is 1.14cm
3/ g, its thickness are 91.2 μ m, under same thickness, if be 1.9cm with the bulk
3The paper of/g substitutes wood-free paper, and it quantitatively is 48g/m
2, be equivalent to 50g/m
2Light paper.1 ton of 50g/m
2The printing area of light paper and 1.6 tons of 80g/m
2The wood-free paper printing area suitable, economic benefit is considerable.
Improve this index of paper bulk and can bring better economic benefit.The paper that adopts chemical pulp to manufacture paper with pulp has lower bulk usually, thus produce that the high bulk paper mainly adopts be chemi-mechanical pulp or be furnished with a spot of chemical pulp.Document rarely has that to adopt the pure chemistry wood pulp be the raw material high bulk paper of manufacturing paper with pulp.
Summary of the invention
The object of the present invention is to provide a kind of manufacture paper with pulp method of high bulk paper of pure chemistry wood pulp that adopts, its paper that produces has the bulk height, and whiteness is high, the characteristics that intensity is good, thus reduce production costs, practice thrift plant resources.
For achieving the above object, the technical scheme that the present invention adopts is:
1) at first; With behind chemical softwood pulp and the chemical hardwood pulp size degradation respectively thin up to make stock quality concentration be 9%～12%; Making beating respectively then, after the making beating respectively thin up make that the mass concentration of chemical softwood pulp is 0.1%～0.3%, the mass concentration of chemical hardwood pulp is 0.2～0.5%;
2) with chemical softwood pulp and chemical hardwood pulp by 15～30: 70～85 weight ratio is mixed, and to the silicate-base high bulk macroparticle filler that wherein adds chemical softwood pulp and chemical hardwood pulp oven-dry weight 20%～40% and fully mix mixed slurry;
3) with cationic starch 90 ℃ of following gelatinizations, control gelatinization concentration is 0.4%～0.8%; The cationic starch that gelatinization is good joins in the slurry that mixes, and its addition is 8～15 kg/ton paper;
4) at last the consumption of retention agent with 0.3～0.5 kg/ton paper added in the slurry; Fully mix the back net forming of going up with slurry and copy paper; Its l Water Paper page or leaf squeeze pressure is 400kPa, and the time is 5min, and baking temperature is made the high bulk paper for (105 ± 2) ℃ obtain chemical wood pulp.
Said step 1) making beating, the beating degree of chemical softwood pulp is 30～35 ° of SR, the beating degree of chemical hardwood pulp is 22～30 ° of SR.
It is 20%～30% mud that described filler should be made into concentration earlier, and then through slagging-off, after the dispersion, it is that 10%～20% mud uses that thin up is made into concentration.
Described retention agent is cationic high molecular polymer, and molecular weight is approximately 3,000,000, and its consumption is 0.3～0.5 kg/ton paper; The incorporation time of retention agent and slurry is 10～30 seconds.
Described filler is a silicate-base high bulk macroparticle filler (200810112618.1; A kind of method of utilizing aluminous fly-ash to prepare calcium silicate micro power); This filler is synthetic by trade waste; Its chemical composition is mainly calcium silicates, and whiteness is 85～90%, and filler powder particulate exists needle-like and the spherical two kinds of forms of surface folding; The length-width ratio of needle-like form particulate is 5: 1～20: 1, and the average grain diameter of surface folding spheroidal particle is 20～40 μ m, and the specific area of filler is 80～130m
2/ g, the pH value is 9.0～10.0, its calcination mass loss (900 ℃) is 10%～20%;
The present invention is high for giving full play to the chemical pulp whiteness; The characteristics that intensity is good; Added high bulk silicate-base large particle size filler, the filling surface fold is spherical, the high surface characteristics are that paper provides good bulk, and the needle-like form of its high-aspect-ratio can be paper and keeps good intensity.Because just making paper bulk and intensity have preferably, the cooperative effect of its two kinds of forms keeps.Not only bulk is high, whiteness is high but also paper strength keeps effective for the paper of this method manufacturing.
