Abstract
The invention relates to a preparation method of tung branch printing paper pulp, which comprises the following steps: (1) carrying out high-speed chopping on cleaned and dried tung branches; (2) fumigating the granular material in 170-200 DEG C steam for 40-60 minutes, wherein acetic anhydride is added in the steam environment in the fumigation process; (3) putting the fumigated material in the step (2) in 85-90 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, glycerol rosin ester and polyurethane resin, and stirring; and (5) continuing adding kaolin with the average particle size of lower than 10 micrometers, aluminum sulfate, 1-2 parts by weight of phenol aldehyde resin, polypropylene amine and tridecanol 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 of tung oil tree branch 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 for tung oil tree branch printing paper pulp, concrete steps are as follows:
(1) the dry tung oil tree branch through cleaning of 100 weight portions is carried out to high speed and shred, become average grain diameter and be the particulate material of 10～50 microns;
(2) particulate material is fumigated 40～60 minutes in the steam of 170～200 ℃, in stifling, in steam ambient, put into the aceticanhydride of 5～15 weight portions;
(3) material after step (2) is stifling is put into the water of 85～90 ℃, adds the alum of 3～5 weight portions simultaneously, stirs 50～80 minutes, then filters, and discharges filtrate, reservation filtrate;
(4) filtrate is dropped into reactor, add 3～6 parts by weight of toluene vulcabond, 2～5 weight portion esterases, 0.7～1.5 weight portion polyurethane resin simultaneously, at 50～60 ℃, stir 140～150 minutes;
(5) continuing to add 7～15 weight portion average grain diameters in reactor is kaolin, 1～3 weight portion aluminum sulfate, 1～2 weight portion phenolic resins, 0.5～2 weight portion polypropylene amine, 0.2～0.3 weight portion tridecanol below 10 microns, stirs and within 30～50 minutes, can obtain this tung oil tree branch printing paper pulp at 35～50 ℃.
The pressure of steam described in step (2) is 2～3 atmospheric pressure.Described in step (3), the parts by weight of water are 200～250 parts.
The technique effect that the present invention is useful is:
The present invention carries out tung oil tree branch preliminary treatment in steam and acid anhydrides, and the steam of High Temperature High Pressure can make the lignin in tung oil tree branch 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 tung oil tree branch fiber.But the fibrous strands in tung oil tree branch 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 tung oil tree branch become the very good material of paper pulp.
