Abstract
Provided is a manufacturing method for printing paper pulp through sawdust. The method comprises the following specific steps that (1), dry sawdust after being washed is exploded through a steam explosion method to obtain granules of the average grain diameter being below 30 micrometers; (2), the granules are put into water, hexamethylene diisocyanate, paraffin and pentaerythritol rosin esters are added into the water at the same time, the temperature of the water rises to 70-80 DEG C, and stirring is carried out for 1-2 hours; (3), water of the temperature being 45-60 DEG C is added into the mixture obtained in the step (2), alums are added, stirring is carried out for 20-35 minutes, then filtering is carried out, filter liquor is discharged, and filter materials are reserved; (4), the filter materials are put into a reaction still, titanium dioxide, starch, polyacrylamide and phenolic resin of which the average grain diameter is below 10 micrometers are added into the filter materials, and then stirring is carried out. Paper products manufactured by the paper pulp is bright in color, firm, durable, good in printability, long in service life and applicable to large-scale industrial production.
Description
Technical field
The present invention relates to print pulp technology for making paper, especially relate to a kind of paper pulp preparation method of environmental protection.
Background technology
After entering 21 century, along with the lasting progress of science and technology, people's living standard is more and more higher, and various material supplies are greatly abundant, and wherein paper products are also seen everywhere.Various newpapers and periodicals, magazine, books, notebook, Notepaper, documents pouch, printing paper, so the use amount of carton, packing box etc. is extremely huge.What manufacture the most of use of these paper products is string, wherein in the majority with the consumption of xylon again.Yet timber overcut meeting brings a series of serious environmental problems, these environmental problems can turn back to affect again people's quality of life.Although the paper using of always advocating thriftiness socially existing, than a large amount of wastes, saves just an utterly inadequate amount, so it is extremely urgent to develop paper products prepared by discarded object.The paper products that utilize at present discarded object to prepare mainly contain recycled writing paper, and recycled writing paper is the paper products that utilize waste and old paper product to manufacture, and have the thicker shortcoming such as more crisp of manufacturing technique complexity, color jaundice obfuscation, papery.
Summary of the invention
The problems referred to above that exist for prior art, the applicant provides a kind of preparation method of sawdust printing paper pulp.Paper products that this paper pulp prepares are bright-colored, tough and tensile durable, printing good, long service life, is applicable to large-scale industrial production.
Technical scheme of the present invention is as follows:
A preparation method for sawdust printing paper pulp, concrete steps are as follows:
(1) utilize steam explosion that the dry sawdust through cleaning of 100 weight portions is carried out to explosion, obtain average grain diameter in the particulate material below 30 microns;
(2) particulate material is put into the water of 60～80 weight portions, added 10～13 weight portion hexamethylene diisocyanates, 1～5 weight portion paraffin, 2～5 weight portion rosin pentaerythritol esters simultaneously, be warming up to 70～80 ℃, stir 1～2 hour;
(3) in the mixture obtaining to step (2), adding temperature is the water of 45～60 ℃, adds the alum of 1～5 weight portion simultaneously, stirs after 20～35 minutes and filters, and discharges filtrate, retains filtrate;
(4) filtrate is dropped into reactor, add 8～12 weight portion average grain diameters is 10 microns of following titanium dioxide, 7～10 weight portion starch, 4～7 weight portion polypropylene amines, 2～3 weight portion phenolic resins simultaneously, stirs and within 30～45 minutes, can obtain this sawdust printing paper pulp at 30～45 ℃.
Described in step (3), the parts by weight of water are 200～220 parts.
The technique effect that the present invention is useful is:
First the present invention utilizes steam explosion preliminary treatment sawdust, makes wherein most of fibrous fracture, and the length of fiber shortens, and cellulosic hydrogen bond is destroyed and reset, and forms more chemism point, and the number that is combined into hydrogen bond between cellulose is increased; Simultaneously this variation makes binding agent can penetrate into the inside of cellulose space structure, increases, adhesion strengthens, and the paper product intensity of producing is improved with the number of the side chain bridge joint of cellulosic molecule.Simultaneously steam blasting can make the ash content in sawdust fiber and lignin is separated opens, and in follow-up cleaning link, can be easy to get rid of.
Subsequently the sawdust after explosion is mixed with the various auxiliary agents that play bonding, bridging effect, the chemism point on fiber molecule is connected to each other, become three-dimensional netted fibre structure.Therefore three-dimensional structure is now comparatively firm, adds hot water to clean and can not destroy this structure, adds alum can promote the precipitation of lignin and ash content simultaneously, after filtration, by lignin and ash separation out, obtains the three-dimensional netted sawdust fiber that purity is higher.Then add filler, sizing material and other auxiliary agents, so just obtained paper pulp that can be practical.
