The emulsion containing the fluorescent whitening agent has the advantages of stable storage and uniform dispersion, can directly act on the surface of a product through a spraying way, is convenient to use, and can effectively avoid decomposition failure of the whitening agent due to postprocessing of the product.
Description
Technical field
The invention belongs to printing and dyeing assistant technical field, have and relate to a kind of emulsion containing fluorescent whitening agent.
Background technology
Fluorescent whitening agent is also known as white dye, and it can improve whiteness and the gloss of material, is all brightening agent commodity
The product that middle heat resistance is best, it not only decomposition temperature high, whiteness is good, and consumption is little, and with in plastics
Additive has the good compatibility, is widely used in weaving, printing and dyeing, papermaking, plastics and paint, decoration
On material.
Fluorescent whitening agent is a kind of physical action to the whitening and brightening effect of material color, near by absorbing in sunlight
The black light of ultraviolet band and launch the blue light of high intensity at visible light wave range, thus not only compensate for
Blue light defect in the reflection light of the white object of yellow head, and add the reflective light intensity of blue wave band,
The whiteness and the brightness that make white object are all significantly increased, and make the color of color body more become clear pleasing.
Fluorescent whitening agent according to chemical constitution can be divided into Stilbene-based, coumarin type, pyrazoline type, benzo uh
Azoles type, the big class of Phthalimide type five.Wherein double styrene-biphenyl fluorescent brightener is current chemistry work
The fluorescent whitening agent that in industry, a class is the most commonly used.It is widely used in detergent, washing cream, liquid detergent
And the every profession and trade of the national economy such as printing and dyeing, papermaking.Owing to it has good dissolubility and dispersibility, in room
Under temperature, it all has good whitening effect to fiber, polyamide, azelon, and its colleague has resistance to hypochlorous acid
The features such as sodium bleaching.
The usual addition of fluorescent whitening agent is plastics or the 0.01-0.05% of polyester granules quality, at various plastics
Before product molding processing or before polyester fiber reels off raw silk from cocoons, it is sufficiently mixed uniformly with material.Owing to its addition is less,
It is difficult in the substrate be uniformly dispersed, easy conglomeration, cause whitening effect the best.For the product only needing top layer to brighten,
Fluorescent whitening agent is blended in masterbatch, adds brightening agent consumption undoubtedly, increase production cost, exist simultaneously
The post processing of product is easily caused brightening agent decomposition failure.
Summary of the invention
It is an object of the invention to provide a kind of emulsion containing fluorescent whitening agent, there is stable storage, be uniformly dispersed
Advantage, product surface can be directly acted on by spraying method, easy to use, effectively prevent brightening agent
The decomposition failure because of product post processing.
The present invention solves the technical scheme that technical problem used:
A kind of emulsion containing fluorescent whitening agent, is made up of following component: 15-30 part fluorescent whitening agent, 20-40
Part water, 8-12 part emulsifying agent and 60-80 part petroleum ether, shown in the structural formula of described fluorescent whitening agent such as formula (I):
Fluorescent whitening agent shown in formula (I), owing to having the structure of double sulfo group on phenyl ring, therefore has good in water
Dissolubility, but the two is relatively big with the polarity spectrum of petroleum ether, and formed system is unstable, is easily layered.To system
Middle addition emulsifying agent, contributes to forming Thermodynamically stable, isotropic transparent dispersion system.Wherein, fluorescence
Brightening agent, water and the emulsion core of a small amount of emulsifying agent constitution system；The interfacial film of emulsifying agent constitution system, its parent
Water section stretches to emulsion core, and hydrophobic part stretches to the continuous phase of petroleum ether；The continuous phase of petroleum ether constitution system.
Petroleum ether and polymeric material have the good compatibility so that emulsion droplets has good prolonging at polymeric surface layer
Malleability, fluorescent whitening agent is more evenly distributed at material surface.Emulsion containing fluorescent whitening agent is directly made by spraying
For product surface, fluorescent whitening agent usage amount can be reduced, it is to avoid fluorescent whitening agent is in product last handling process
Decompose inefficacy.
As preferably, described emulsifying agent is made up of the Polyethylene Glycol that mass ratio is 1:1-3 and dodecyl sodium sulfate,
The synergism of two kinds of emulsifying agents makes emulsion system stability more preferably.
As preferably, the boiling point of described petroleum ether is 30-60 DEG C, and the emulsion containing fluorescent whitening agent is through spraying effect
After product surface, can by the way of drying the water in removing system and petroleum ether, therefore need to select low boiling
Point petroleum ether.
It is further preferred that the molecular weight of described Polyethylene Glycol is 400-600, it is liquid under room temperature.
It is further preferred that described emulsion is made up of following component: 20 parts of fluorescent whitening agents, 30 parts of water, 10 parts of emulsifyings
Agent and 70 parts of petroleum ether.
The preparation method concrete operation step that invention also provides described emulsion is: increased by 15-30 part fluorescence
White agent adds in 20-40 part water, stirs to after being completely dissolved, adds 8-12 part emulsifying agent and 60-80 part oil
Ether, after using mulser room temperature emulsifying 30 minutes, stops emulsifying, stands.
As preferably, described emulsifying agent is made up of the Polyethylene Glycol that mass ratio is 1:1-3 and dodecyl sodium sulfate,
The molecular weight of described Polyethylene Glycol is 400-600.
As preferably, the boiling point of described petroleum ether is 30-60 DEG C.
The invention have the benefit that
Emulsion containing fluorescent whitening agent provided by the present invention, has stable storage, finely dispersed advantage, can
To directly act on product surface by spraying method, easy to use, effectively prevent brightening agent because locating after product
Manage and decomposition failure.
