Abstract
The invention relates to a bleached cotton-stalk pulp with function of disinfection and sterilization and the preparing method for the pulp, which is to solve the problem associated with prior paper pulp that can't disinfect and sterilize, and is a bleached cotton-stalk pulp made from cotton-stalk natural-color pulp by bleaching with hydrogen peroxide. In the bleached cotton-stalk pulp, additionally some nanometer titanium whiting powder is added. The added volume of the nanometer titanium whiting powder is 0.05-3% of the dry weight of the bleached cotton-stalk pulp. The preparing method comprises in sequence the following procedures: 1) crushing; 2) separating into cellulose bundles by a rubbing and separating machine; 3) adding water onto the cellulose bundles in a moistening bin, heating up to 90-100 centigrade till the cellulose bundles soften; 4) rough grinding by a hi-concentration disc mill, extruding out lignin and black liquid by a pulp-extruding machine to get pulp in natural color; 5) adding water onto the natural-color pulp in a reaction bin, milling and bleaching the pulp by hydrogen peroxide decolorizer, extruding out white liquid by a pulp-extruding machine to get bleached cotton-stalk pulp; 6) neutralizing the extruded black and white liquid, defecating with oxidizing flocculator, the clean water from that will be guided into the moistening bin and the reaction bin for circulating. The invention has the functions of disinfection and sterilization, can be used for making sanitary napkins, napkin paper, hand towels and wall paper, etc. with disinfection function.
Description
Technical field
The present invention relates to a kind of paper pulp, particularly relate to a kind of cotton stalk bleach pulp and preparation method thereof with disinfection function.
Background technology
At present, the kind of paper pulp is various in style, wherein can be divided into the vegetation mixed pulp that straw pulp, wood pulp and vegetation raw material are made according to raw material type.The cotton stalk paper pulp that the rhizome of Malvaceae plant--cotton is made has two kinds of attributes of straw pulp and wood pulp simultaneously, and still, because the restriction of technical conditions and cost condition, cotton stalk can only be produced the cotton stalk master grind, does not also see the report of cotton stalk production bleached pulp.
Summary of the invention
The object of the invention is to overcome the above-mentioned defective of prior art, and a kind of cotton stalk bleach pulp with disinfection function is provided, and the object of the invention also is to provide its preparation method.
For achieving the above object, to have the cotton stalk bleach pulp of disinfection function be the cotton stalk bleach pulp that the cotton stalk natural color pulp is made after with hydrogen peroxide bleaching in the present invention.With containing active oxygen in the cotton stalk bleach pulp of making behind the hydrogen peroxide bleaching, so it has disinfection function with sterilizing effect.In addition, with in the cotton stalk bleach pulp of making behind the hydrogen peroxide bleaching except that active oxygen, also contain other NF sterilizing composition, may be in the cotton stalk intrinsic composition or in process of production by cotton stalk composition bactericidal activity composition newly-generated or that activate.Through test, paper that this cotton stalk bleach pulp is made or cotton stalk bleach dry pulp can kill in the air and water in common transmittable germ and virus.
As optimization, with also being added with the nano grade titanium white powder in the cotton stalk bleach pulp of making after the bleaching of hydrogen peroxide decolorizer.The nano grade titanium white powder has disinfection function, also has disinfection function so add the cotton stalk bleach pulp of nano grade titanium white powder.
As optimization, the addition of described nano grade titanium white powder is the 0.05-3% of cotton stalk bleach pulp dry weight.In this scope, has desirable disinfection effect.
As optimization, described cotton stalk natural color pulp is that cotton stalk is made through following method:
1), pulverizes;
2), be divided into fibre bundle with kneading or grinding leaser;
3), fibre bundle being converted water in soaking into the storehouse is heated to 90-100 ℃ and makes fibre bundle softening;
4), with high concentration plate mill corase grind, extrude lignin and black liquor with press master again, natural color pulp.Method is easy, and is workable.
The preparation method that the present invention has the cotton stalk bleach pulp of disinfection function comprises the following steps: successively
1), pulverizes;
2), be divided into fibre bundle with kneading or grinding leaser;
3), fibre bundle being converted water in soaking into the storehouse is heated to 90-100 ℃ and makes fibre bundle softening;
4), with high concentration plate mill corase grind, extrude lignin and black liquor with press master again, natural color pulp;
5), natural color pulp carries out defibrination, bleaching with the hydrogen peroxide decolorizer convert water in reaction warehouse after, extrude white liquid with press master and obtain cotton stalk bleach pulp;
6), with the black liquor extruded and white liquid neutralization, add the clarification of oxidation flocculant after, the gained clear water imports to soak in storehouse and the reaction warehouse and recycles.Method is easy, and is workable, more compliance with environmental protection requirements.
As optimization, be the fibre bundle of cotton stalk being made long 10-50mm with kneading or grinding leaser; Fibre bundle is converted the water ratio in soaking into the storehouse be 1: 3, and the softening time of infiltration of soaking in the storehouse is 70-100 minute; Step 5) is to be to convert at 1: 1 to deliver to behind the water to add the hydrogen peroxide decolorizer in the high concentration plate mill and carry out 40% high consistency refining, bleach into cotton stalk bleach pulp with spiral propeller in proportion with natural color pulp.Method is easy, and is workable.
As optimization, after the natural color pulp bleaching,, also be blended into the nano grade titanium white powder that accounts for cotton stalk bleach pulp dry weight 0.05-3% extruding with press master before white liquid obtains cotton stalk bleach pulp.So design helps mixing.
As optimization, the proportioning of hydrogen peroxide and natural color pulp dry weight is 2%.Here hydrogen peroxide is meant the hydrogen peroxide of amounting to into 100% content.So design, reasonable mixture ratio.
After adopting technique scheme, the cotton stalk bleach pulp that the present invention has disinfection function has the advantage of disinfection function, can be used for making sanitary napkin, napkin paper, towel and wallpaper etc. with sterilizing function.
The specific embodiment
Do further explanation below in conjunction with instantiation:
The cotton stalk bleach pulp that the present invention has a disinfection function is the cotton stalk bleach pulp that the cotton stalk natural color pulp is made after with hydrogen peroxide bleaching.Described cotton stalk natural color pulp is that cotton stalk is made through following method:
1), pulverizes;
2), be divided into fibre bundle with kneading or grinding leaser;
3), fibre bundle being converted water in soaking into the storehouse is heated to 90-100 ℃ and makes fibre bundle softening;
4), with high concentration plate mill corase grind, extrude lignin and black liquor with press master again, natural color pulp.
