Description

A kind of modified lignin dispersant of disperse dye and preparation technology thereof
Technical field
The invention belongs to field of fine chemical, specially refer to a kind of modified lignin dispersant of disperse dye and preparation technology thereof.
Background technology
The world today, the deposit of oil, natural gas source is limited, and their research, development and utilization is on the rise to the impact that ball ecological environment brings, and this has impelled the macromolecular material take natural resource as raw material to be greatly developed.Xylogen is one of the abundantest, reproducible natural polymer child resource of occurring in nature.Whole world terrestrial plant can produce 50,000,000,000 tons of xylogen every year, and the industrial lignin that wherein produces in the cooking waste liquor of pulp and paper industry has 5,000 ten thousand tons.At present, the pulp and paper industry of China is take alkali and sulfate cooking slurrying as main, some large-scale enterprises in pulp and paper industry can be eliminated the rear recovery of black liquor of pulp making burning alkali lye by alkali recovery technology the pollution of black liquor of pulp making, but the method can cause the huge waste of Liginon Resource.Therefore xylogen is not also well utilized so far, China only approximately 6% xylogen utilized.How effectively to make good use of this renewable resources of xylogen, improve the starting point that its added value has become every researcher research.
Dispersed dye are the water-soluble lower nonionic dyes of a class.Be used for the earliest the dyeing of cellulose acetate fibre, be called cellulose acetate dye.Along with the development of synthon, polyamide fibre, terylene occur in succession, and dyestuff has been proposed Secretary.The domestic alone dispersion agent that waits the dyestuff post-treatment in reduction is estimated to want 6 ~ 100,000 tons every year.Good and bad quality and the whole dyeing course that directly affects dyestuff of dispersion agent, therefore, dispersion agent is very important.The dye dispersant that generally uses on the domestic and international market at present mainly contains several lower several types: (1) naphthalene sulfonic acidformaldehyde condensation product dispersion agent; (2) polycarboxylic acid series dispersion agent; (3) modified lignin resin class dispersion agent.
Wherein the heat-resistant stability of naphthalene sulfonic acidformaldehyde condensation product dispersion agent is not high, generally only have 120 ~ 130 ℃, its raw material (methylnaphthalene) can not meet the needs of production far away simultaneously, and product cost is higher, and then affect the price of naphthalene sulfonic acidformaldehyde condensation product dispersion agent product, thereby be unfavorable for that product applies in analyzing dyestuff.And the severe reaction conditions of polycarboxylic acid series dispersion agent, complex process, industrialization cost are high, and simultaneously, the monomer coverage rate of existing activity polymerizating technology is narrow, is mainly the monomers such as vinylbenzene, (methyl) esters of acrylic acid, and the designability of molecular structure is less.And modified lignin resin is mainly that as the advantage of dye dispersant (1) raw material sources are wide, and more easily obtaining, cost is lower simultaneously; (2) fuel system with numerous species has good compatible and good dispersing property.Xylogen also has the problem of some more difficult breakthroughs as dye dispersant, as dyeing and the heat-resistant stability thereof of xylogen to fiber but meanwhile.Overcoming of these difficult points become the focus that domestic and international expert competitively studies.
In recent years, the research of modified lignin resin dye dispersant was mainly concentrated on xylogen was carried out suitable chemically modified, to improve its performance, especially resistance toheat.Wang K C utilizes polyoxyethylene glycol ether epoxy EO-1, EO-2, EO-3 as dispersing auxiliary, can with the composite use of sulfonated lignin.But composite hydrophilic, lipophilic group and the surfactivity thereof that can not change in the lignosulfonic acid molecules of salt, and price is higher.Therefore, sulfonated lignin are carried out chemical modification, could prepare efficient modified lignin mahogany sulfonate dispersion agent (US 6066183).Dilling P utilizes V-Brite B to carry out pre-treatment to xylogen, then is reacted by S-WAT and aldehyde and modified lignin resin, to improve the thermotolerance (US 4338091) of xylogen.Wei Handaocai etc. are with electrooxidation and sulfomethylation method that physics and chemistry combines, provide a kind of reaction conditions gentle, do not produce public hazards, and the method (ZL 00131005.4) of the good preparing disperser by improving lignin of product dispersing property.
Therefore, if take xylogen as raw material, develop the modified lignin vat dye dispersing agent with certain sulfonation degree by chemical modification, not only greatly reduce the price of vat dye dispersing agent product, be conducive to applying of modified lignin vat dye dispersing agent, and will further widen the range of application of xylogen, and improve its added value, also improve simultaneously Enterprise Integrated and utilize xylogen and solve the enthusiasm that pulping back liquor pollutes, promote China's pulping and paper-making industry to continue, develop in a healthy way.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, it is poor to improve the added value of xylogen and solve traditional dispersant of disperse dye heat-resistant stability, and the high in cost of production problem provides a kind of modified lignin dispersant of disperse dye and preparation technology thereof.This technique is by directly utilizing the black liquor that produces in pulp industry, the preparation dispersant of disperse dye, with reduce or eliminate produce and use procedure in to the environment produced pollution, on the basis that greatly reduces product cost, improved the performances such as the dispersion force of product and heat-resistant stability.
