Abstract
The present invention provides a composition of a liquid fluorescent bleaching agent, which comprises: 10 to 30% of fluorescent bleaching agent dye, 20 to 40% of fatty alcohol polyoxyethylene ether, 10 to 30% of polyethyleneglycol, 10 to 30% of diethylene glycol, 5 to 40% of water and 0.1 to 5% of sodium benzoate, wherein the fluorescent bleaching agent dye is a sulfonic group styryl biphenyl (CBS) compound, the structure is in formula (I), M represents hydrogen, alkali metal, magnesium or ammonium salts, and the replacing position of the sulfonic group can be an ortho position, a meta position or a para position of vinyl. The composition is used for whitening for washing agents and high-grade paper, and has favorable stability in a relatively wide temperature range.
Description
Affiliated technical field
The present invention relates to a kind of transparent liquid white dyes (FWA:CBS) composition that washing composition and paper industry are used.
Background technology
Usually the commercially available high-grade white dyes that is used for washing composition and high-grade paper is Powdered or granular product, and generally there is the disadvantage of dust pollution in this product in manufacturing and use, be unfavorable for environment protection and operator ' s health.The invention of the white dyes of this liquid dosage form has not only overcome above-mentioned difficulties, and have that fluorescence is strong, whiteness is high, outward appearance is as clear as crystal, easy to use, be easy to characteristics such as automatization control.
Solid state fluorescence whitening agent CBS is a kind of sulfonic group that has, compound soluble in water, but its solubleness in water is little, only under higher temperature (as 80-100 ℃), a higher solubleness is arranged, solubleness is then lower when temperature reduces, this characteristic makes it be difficult for being prepared into a kind of simple aqueous solution, and concentration higher and stable being difficult for separates out.In recent years, the aqueous fluorescent brightener CBS that contains tensio-active agent all has report in many patents.
Patent GB 2,294, and 708 have reported that a kind of what add a small amount of PVOH is the prescription of the liquid brightener of solvent with polyoxyethylene glycol and water, but they report that prepared product has only 5 days 50 ℃ steady time; Chinese patent CN1,179,466 reports are a kind of to be the preparation method of the liquid brightener of solvent with Soxylat A 25-7 and water mixture, but this patent does not illustrate its stability and period of storage, thereby lack certain practical value; Equally, U.S. Pat 6,660,705 have reported that with fatty alcohol-polyoxyethylene ether and glycerine be the liquid formulations of mixed solvent, but this patent does not illustrate its stabilising characteristic equally; It is the preparation method of the liquid brightener of solvent with polyoxyethylene nonylphenol ether, glycerol and water mixture that patent CN1480519 has also reported a kind of, but the nonyl phenol compound has become the forbidding kind of washing industry in Europe.
Summary of the invention
Development along with high-grade cleaning product and high-grade paper industry, press for a kind of easy to use, be easy to the liquid brightener product that automatization is added, steady time is long, purpose of the present invention is exactly the defective that overcomes existing powdery product, the composition of liquid fluorescent bleaching agent that provides a kind of easy to prepare, good stability, nontoxic, no burn into to be easy to store.
Another object of the present invention provides a kind of automatization control, composition of liquid fluorescent bleaching agent safety, easy to use of being easy to that is used for cleaning product, high-grade paper.

Wherein, the white dyes dyestuff is a 4,4'-Bis[2-(2-sulfophenyl)ethenyl, and its structural formula is as (I):
In the formula: M represents hydrogen, basic metal, magnesium or ammonium salt, and sulfonic the position of substitution can be ortho position, a position or the contraposition of vinyl).Concrete structure is the mixture of any or their any ratios in the compound shown in (II-IV).
Used fatty alcohol-polyoxyethylene ether is C in the compositions of fluorescent whitening agents of the present invention
6-C
18Fatty Alcohol(C12-C14 and C12-C18) makes through 3-20 oxyethane ethoxylation doubly.Most preferably be that moieties has C
10-C
15Individual carbon atom, ethoxylation degree are 8-12.
The molecular weight of used dispersion agent polyoxyethylene glycol compounds is between the 200-5000 in the compositions of fluorescent whitening agents of the present invention.Be preferably 200-600.
Composition of liquid fluorescent bleaching agent of the present invention prepares by the following method:
Add in the reactor with any among white dyes II, III, the IV or with nonionogenic tenside, dispersion agent, sanitass such as the mixture of arbitrary proportion and Soxylat A 25-7s, add an amount of water again, heating for dissolving, filtration, cooling get final product.
Used alkyl polyoxyethylene ether is a technical characterictic of the present invention among the present invention, the contriver finds by adopting the Soxylat A 25-7 and the polyoxyethylene glycol mixture of certain proportioning, add a spot of dispersion agent, not only make the white dyes raw material have good solubility, and can reach higher concentration, and keep the security of secular stability and use.
