Abstract
The invention discloses a preparation method of a corncob printing paper pulp. The preparation method specifically comprises the steps of (1) performing high-speed mincing on washed and dried corncobs; (2) fumigating a granular material for 30-50 minutes in steam of which the temperature is 180-210 DEG C, and adding acetic anhydride hydrogen peroxide into the steam environment while fumigating; (3) putting the fumigated material obtained in step (2) into water of which the temperature is 80-95 DEG C, adding alum at the same time, stirring, then filtering, discharging the filtrate and keeping a filter material; (4) putting the filter material into a reaction kettle, adding polyethylene wax, pentaerythritol rosin ester and polyamide resin at the same time, and stirring; (5) adding trihydroxy aluminum, rosin, urea-formaldehyde resin, polyoxyethylene and turpentine of which the average particle size is less than 10 microns, and stirring. According to the preparation method, waste plant fibers are used, a prepared paper product is bright in color, tough and durable, good in printability, long in service life and 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 corncob 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 corncob printing paper pulp, concrete steps are as follows:
(1) the dry corncob through cleaning of 100 weight portions is carried out to high speed and shred, become average grain diameter and be the particulate material of 20～30 microns;
(2) particulate material is fumigated 30～50 minutes in the steam of 180～210 ℃, in stifling, in steam ambient, put into aceticanhydride and 1～2 part of hydrogen peroxide of 5～10 weight portions;
(3) material after step (2) is stifling is put into the water of 80～95 ℃, adds the alum of 3～5 weight portions simultaneously, stirs 60～70 minutes, then filters, and discharges filtrate, reservation filtrate;
(4) filtrate is dropped into reactor, add 2～4 weight account polyethylene waxes, 3～5 weight portion rosin pentaerythritol esters, 2～3 weight parts of polyamide resins simultaneously, at 50～70 ℃, stir 130～150 minutes;
(5) continuing to add 12～25 weight portion average grain diameters in reactor is aluminium trihydrate, 3～4 weight portion rosin, 1～3 weight portion Lauxite, 1～3 weight portion polyethylene glycol oxide, 0.1～0.5 weight portion turpentine oil below 10 microns, stirs and within 30～50 minutes, can obtain this corncob printing paper pulp at 40～50 ℃.
The pressure of steam described in step (2) is 2～3 atmospheric pressure.Described in step (3), the parts by weight of water are 220～230 parts.
The technique effect that the present invention is useful is:
The present invention carries out corncob preliminary treatment in steam and acid anhydrides, the steam of High Temperature High Pressure can make the lignin in corncob separated, the moisture that acid anhydrides runs in steam becomes acetic acid, has played the effect of separating lignin and bleached fiber, and hydrogen peroxide has been strengthened bleaching.Then pretreated material is put into hot water, add alum can promote the precipitation of lignin, after filtration, by lignin separation out, obtain corncob fiber.But the fibrous strands in corncob 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 corncob become the very good material of paper pulp.
