Abstract
The invention discloses a method for improving vividness of colorized parchment and effectively preventing fading, and belongs to the technical field of paper making. The method comprises the following steps: adding liquid organic pigment into pulp; and firmly combining pigment ions with fibers under the action of crosslinked cationic alkyl polyamine with high charge density and low molecular weight. The organic pigment has bright color, and the pigment ions are stably adhered to the fibers through the combination of the cationic alkyl polyamine, so that the colorized parchment has bright color and luster and does not fade; and according to the method, the parchment with different color depths can be produced.
Description
Technical field
The present invention relates to a kind of method that improves colored parchment vividness and effectively prevent from fading, belong to pulp technology for making paper.
Background technology
Parchment also is template, and it generally is that body paper makes it parchmentizing through the sulfuric acid dipping first after copying into body paper take chemical wood pulp and rag stock as raw material, and then through processing such as depickling, washing, neutralization, plasticizings, batching at last becomes parchment.
The color plant parchment belongs to high-grade special paper, is characterized in: product technology content is high, and added value is high, and the technology barriers that come into the market are high, have a extensive future.At present, domestic manufacturer is few, and produces colored parchment and use direct dyes that fiber is dyeed always, and the salt (NaCl) of adding 5% is obtained than shade wood pulp fibre in the slurry.Adopt body paper that this colouring method obtains again behind persulfuric acid impregnation processability (being that parchmentizing is processed), the paper color and luster is gloomy and in use fade extremely easily, dyes on the contactant.For many years, the development that color is gloomy, serious this two large technical problem of the phenomenon that fades in the use procedure is perplexing domestic colored parchment product always restricts the lifting of product specification.
Summary of the invention
The problem that the present invention has overcome that existing colored parchment color is gloomy, easily fade in the use procedure provides a kind of method that improves colored parchment vividness and effectively prevent from fading, and the method has thoroughly solved the problems referred to above.
Technical scheme of the present invention is: a kind of method that improves colored parchment vividness and effectively prevent from fading, it is characterized in that,
(1) add the mixing wood pulp of accomplishing fluently in mixing pit, the beating degree of described mixing wood pulp is 30-40 ° of SR, and concentration is 3-4%, alpha-cellulose content 90% ± 5%;
(2) organic pigment after will diluting adds and mixes in the wood pulp, and with mix wood pulp and fully mix; The addition of described organic pigment adopts with the stainless steel dissolving tank thin up 20-30 that stirs and doubly uses for mixing the 0.001-5% of wood pulp gross mass.
(3) CATION that then adds dilution is gathered the alkylamine color-fixing agent, fully stirs, and after mixing, sends into machine hand's section and copies into the sheepskin body paper; The addition of the poly-alkylamine color-fixing agent of described CATION is the 0.1-1.0% of mixing wood pulp gross mass, adopts the doubly rear use with the stainless steel dissolving tank thin up 20-30 that stirs.
Described mixing wood pulp preferably adopts 20～40% softwood pulp and 80～60% hardwood pulp.Described organic pigment, red, yellow is AZO pigments, and blue, green is phthalein mountain valley with clumps of trees and bamboo pigment, and black is generally carbon black pigment.The Cartafix CB Liqid(trade name that the poly-alkylamine color-fixing agent of described CATION is preferably produced by Sweden Clariant chemical industry Co., Ltd: color-fixing agent), it is faint yellow viscous liquid; Chemical composition: CATION is gathered alkylamine; Solid content 44%, density (20 ℃): 1.147kg/L, pH3.8, viscosity: 20 ℃ is 435mPa.s, 0 ℃ is 910mPa.s.
The invention has the beneficial effects as follows: the present invention adopts and adds the liquid organic pigment in the slurry, the effect that gathers alkylamine through high charge density, low molecular weight, crosslinked CATION again, the pigment ion is combined with fiber securely, because organic pigment itself is bright in luster, and the combination by the poly-alkylamine of CATION, pigment is anchored on the fiber ion stabilizedly, and it is bright in colour therefore to have reached colored parchment, the purpose that does not fade.Utilize the method can produce the deep mixed parchment of colour system, such as multiple colors such as yellow, orange, bright red, tangerine, pink, fuchsin, emerald green, light green, blackish green, light blue, dark blue, grey, lilac, purple, true qualities, dark brown, shallow palm fibre, dark-grey, light gray, black.
The specific embodiment

Batching: mix 1.05 tons of wood pulps, blue (the phthalein mountain valley with clumps of trees and bamboo pigment) 9.4 kilograms of organic pigment, yellow (AZO pigments) 0.57 kilogram of organic pigment, CATION is gathered 5 kilograms in alkylamine color-fixing agent (the Cartafix CB Liqid that Sweden Clariant chemical industry Co., Ltd produces, solid content 44%).
Described mixing wood pulp is: 40% softwood pulp (alpha-cellulose content 90% ± 2%) and 60% hardwood pulp (alpha-cellulose content 90% ± 2%), beating degree is 30-40 ° of SR, concentration 3.5%.
Described organic pigment is blue and the mixing of organic pigment Huang is rear adopts with 25 times of afterwards uses of the stainless steel dissolving tank thin up that stirs; Described polyurethane/cationic base amine color-fixing agent adopts be dissolved in water 25 times of tank dilutions of the stainless steel that stirs and uses afterwards.
Method: add in mixing pit and mix wood pulp, its concentration is 3.5%; The organic pigment of the liquid after the dilution is added in the mixing wood pulp, and fully mix with wood pulp; Then add the poly-alkylamine color-fixing agent of CATION after diluting, fully stir, after mixing, send into paper machine and copy into paper, paper after copying into makes it parchmentizing through the sulfuric acid dipping first, and then through processing such as depickling, washing, neutralization, plasticizings, batching at last becomes parchment.Its finished product index is as shown in table 1.
Table 1 finished product parchment performance indications
The parchment that embodiment 1 produces is bright in luster, carries out the poach contrast experiment with the like product (direct dyeing method) of domestic production, and experimental result is as shown in table 2 below.The poach experiment is a kind of method that whether fades in the use procedure of check paper, be specially: take by weighing 5 gram over dry patterns, tear into the scraps of paper of 2-3cm, put into small beaker, add 100ml distilled water, the above is stamped surface plate, in electric furnace or water-bath, heat, keep little and boiled 15 minutes, after the cooling scraps of paper are pulled out, observe the color in the water.
