Abstract
The invention relates to a preparation method of greening waste printing paper pulp, which comprises the following steps: (1) carrying out high-speed chopping on cleaned and dried greening waste; (2) fumigating the granular material in 170-180 DEG C steam for 30-60 minutes, wherein acetic anhydride is added in the steam environment in the fumigation process; (3) putting the fumigated material in the step (2) in 70-85 DEG C water, adding alum, stirring, filtering, discharging the filtrate, and maintaining the filter material; (4) adding the filter material into a reaction kettle while adding toluene diisocyanate, polyethylene wax and acrylic resin, and stirring; and (5) continuing adding calcium carbonate with the average particle size of lower than 10 micrometers, aluminum sulfate, phenol aldehyde resin, polyoxyethylene and tributyl phosphate into the reaction kettle, and stirring. The paper product prepared from waste plant fibers by the method has the advantages of bright color, high toughness, high durability, favorable printing performance and long service life, and is suitable for 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 who afforests discarded object printing paper pulp.The string that this method utilization is discarded, the paper products that prepare 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 who afforests discarded object printing paper pulp, concrete steps are as follows:
(1) the dry greening discarded object through cleaning of 100 weight portions is carried out to high speed and shred, become average grain diameter and be the particulate material of 10～30 microns;
(2) particulate material is fumigated 30～60 minutes in the steam of 170～180 ℃, in stifling, in steam ambient, put into the aceticanhydride of 10～12 weight portions;
(3) material after step (2) is stifling is put into the water of 70～85 ℃, adds the alum of 3～5 weight portions simultaneously, stirs 70～90 minutes, then filters, and discharges filtrate, reservation filtrate;
(4) filtrate is dropped into reactor, add 13～19 parts by weight of toluene vulcabond, 4～8 weight account polyethylene waxes, 2～9 parts by weight of acrylic acid resins simultaneously, at 60～80 ℃, stir 120～130 minutes;
(5) continuing to add 18～20 weight portion average grain diameters in reactor is calcium carbonate, 2～4 weight portion aluminum sulfate, 0.5～1.8 weight portion phenolic resins, 3～4 weight portion polyethylene glycol oxides, 0.5～1 weight portion tributyl phosphate below 10 microns, stirs and within 30～50 minutes, can obtain this greening discarded object printing paper pulp at 30～40 ℃.
The pressure of steam described in step (2) is 2～3 atmospheric pressure.Described in step (3), the parts by weight of water are 220～250 parts.
The technique effect that the present invention is useful is:
The present invention carries out greening discarded object preliminary treatment in steam and acid anhydrides, and the steam of High Temperature High Pressure can make the lignin of afforesting in discarded object separated, and the moisture that acid anhydrides runs in steam becomes acetic acid, has played the effect of separating lignin and bleached fiber.Then pretreated material is put into hot water, add alum can promote the precipitation of lignin, after filtration, by lignin separation out, obtain afforesting discarded object fiber.But the fibrous strands in greening discarded object is shorter, not treated words cannot be prepared into pliable and tough level and smooth paper.The application, by adding various auxiliary agents, is linked into three-dimensional reticular fiber by staple fibre, thereby makes to afforest the very good material that discarded object becomes paper pulp.
