Abstract
The invention discloses a highly water-soluble disulfonic acid fluorescent whitening agent composition, relates to the fluorescent agent used in the field of paper-making, printing, detergent industries and the like and aims to solve the defects of easy congregation and weak solubility of the existing disulfonic acid whitening agents during the use process. The whitening agent composition comprises the following components in parts by weight: 40-60 of two or more of the fluorescent whitening agent products with a general formula (1), 8-15 of cosolvent, 15-25 of urea, 5-14.5 of acid-alkali regulator, 0.5-3 of water softener, and 0.5-5 of wetting agent. According to the invention, the whitening agent composition solves the defects of the powdered disulfonic whitening agents of easy congregation and difficult dissolution during the use process, and has better whitening effect, and excellent hydrophilicity and water solubility compared with the single disulfonic fluorescent whitening agent products.
Description
Technical field
The present invention relates to the white dyes of the sector applications such as papermaking, printing and dyeing and washing composition, be specifically related to a kind of disulfonic acid fluorescent whitening agent composition of highly water-soluble.
Background technology
Triazinylaminodiphenethylenes ethylenes fluorescence brightener (being called for short: disulfonic acid fluorescent whitening agent) containing two sulfonic acid groups in molecular structure, because cost performance is high, be widely used in the fields such as papermaking, printing and dyeing and washing composition, the product of the current mainly powder form of this series products, but there is following problem in this series products: poorly water-soluble, and solubleness is low; Wetting ability is poor, and dissolution rate is slow, easily unites in water; Use inconvenience etc.Therefore, develop a kind of water-soluble height, whitening effect is good and cost performance is high white dyes product has important practical significance.
Patent CN101760048A reports and passes through grinding technics, make whitening agent fineness≤5 micron, although make the enhanced dissolution rate of particle fluorescence whitening agent in water obtained, alleviate the phenomenon of uniting in use, do not solve disulfonic acid fluorescent whitening agent poorly water-soluble, problem that solubleness is low; And this technique needs special milling apparatus, facility investment is large, and operation energy consumption is high.
English Patent GB9621421 describes in two or more white dyes filter cake, adds the liquid product that nonionogenic tenside and polar solvent obtain white dyes; Chinese patent CN102093750A reports in white dyes filter cake, adds the liquid product that deionized water, cellosolve, polyoxyethylene glycol compounds and multicomponent alcoholics compound etc. obtain white dyes; The liquid product that these two patents obtain solves powder-product wetting ability and water miscible problem, but liquid preparation derives other problem, as: the quality guaranteed period is short, is generally no more than 6 months; Liquid product effective constituent is generally at 30%-35%, and active constituent content is lower, packaging and trucking costs relatively high, especially for export product, problem is more outstanding.
Up to the present, a kind of desirable water-soluble height, cost performance is high and whitening effect is good disulfonic acid fluorescent whitening agent is not also had.
Summary of the invention
The present invention is in order to easily uniting of solving that existing disulfonic acid fluorescent whitening agent in use exists, poorly soluble defect, and provides a kind of disulfonic acid fluorescent whitening agent composition of highly water-soluble.
The present invention is achieved by the following technical solutions:
A disulfonic acid fluorescent whitening agent composition for highly water-soluble, is made up of each component of following weight part:
Two kinds and the two or more white dyes product 40 ~ 60 represented by general formula (1);
Solubility promoter 8 ~ 15;
Urea 15 ~ 25;
Acid-base modifier 5 ~ 14.5;
Water-softening chemicals 0.5 ~ 3;
Wetting agent 0.5 ~ 5.
During preparation, first the disulfonic acid fluorescent whitening agent of two or more powdery is mixed, by other each components of above-mentioned parts by weight, insert in blending device, mix, obtain the disulfonic acid fluorescent whitening agent composition of highly water-soluble.
Wherein said solubility promoter is one or more in maltose, Zulkovsky starch and maltodextrin;
Described acid-base modifier is one or more in soda ash, sodium bicarbonate, salt of wormwood;
Described water-softening chemicals is one or more in tripoly phosphate sodium STPP, tertiary sodium phosphate, Sodium phosphate dibasic, Sodium hexametaphosphate 99;
Described wetting agent is Nekal BX, Igepon T or their mixture;
By product of the present invention with etc. the deionized water of weight mix, being heated to about 45 DEG C, obtaining the transparent aqueous solution that 1% optical extinction coefficient is 120 ~ 140, after solution is down to normal temperature, placing without separating out phenomenon for a long time; If use single disulfonic acid fluorescent whitening agent, as BA or VBL, under identical condition, be heated to about 45 DEG C, cannot be entirely molten.
Compared with prior art, the invention solves that powder disulfonic acid fluorescent whitening agent is in use united, the not defect such as good dissolving, more single disulfonic acid fluorescent whitening agent product has better whitening effect, more excellent wetting ability and water-soluble.
