Abstract
The invention relates to a preparation method of straw printing paper pulp, which comprises the following steps: (1) carrying out high-speed chopping on cleaned and dried straws; (2) fumigating the granular material in 180-200 DEG C steam for 30-35 minutes, wherein acetic anhydride is added in the steam environment in the fumigation process; (3) putting the fumigated material in the step (2) in 80-90 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 isophorone diisocyanate, paraffin, glycerol rosin ester and alkyd resin, and stirring; and (5) continuing adding amorphous silica with the average particle size of lower than 10 micrometers, rosin, urea-formaldehyde resin, polypropylene amine and silicone oil into the reaction kettle, and stirring to obtain the straw printing paper pulp. 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 stalk 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 stalk printing paper pulp, concrete steps are as follows:
(1) the dry stalk through cleaning of 100 weight portions is carried out to high speed and shred, become average grain diameter and be the particulate material of 10～20 microns;
(2) particulate material is fumigated 30～35 minutes in the steam of 180～200 ℃, in stifling, in steam ambient, put into the aceticanhydride of 15～20 weight portions;
(3) material after step (2) is stifling is put into the water of 80～90 ℃, adds the alum of 3～5 weight portions simultaneously, stirs 50～70 minutes, then filters, and discharges filtrate, reservation filtrate;
(4) filtrate is dropped into reactor, add 5～10 weight portion isophorone diisocyanate, 2～3 weight portion paraffin, 3～7 weight portion esterases, 1～2 weight portion alkyd resins simultaneously, at 50～80 ℃, stir 120～150 minutes;
(5) continuing to add 10～20 weight portion average grain diameters in reactor is unformed silica, 2～4 weight portion rosin, 1～3 weight portion Lauxite, 1～3 weight portion polypropylene amine, 0.1～0.5 weight portion silicone oil below 10 microns, stirs and within 30～50 minutes, can obtain this stalk printing paper pulp at 30～50 ℃.
The pressure of steam described in step (2) is 2～3 atmospheric pressure.Described in step (3), the parts by weight of water are 200～230 parts.
The technique effect that the present invention is useful is:
The present invention carries out stalk preliminary treatment in steam and acid anhydrides, and the steam of High Temperature High Pressure can make the lignin in stalk 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 stalk fibre.But the fibrous strands in stalk 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 stalk become the very good material of paper pulp.
