Abstract
The invention discloses a method for preparing an easily-stored, dust-free and easily-dispersed hollow micro-particle solvent dye, which comprises the following specific steps of: (1) putting a dye filter cake and a compound surfactant into a sanding pot to perform coarse grinding and adding an antifoaming agent in the coarse grinding process; (2) transferring the coarsely ground material to a homogenizer and performing fine grinding to make the particle size of dye particles reach 1 to 80 microns; and (3) conveying the finely ground material to a spray drying tower by using a high-pressure pump and performing spray drying granulation to obtain the hollow micro-particle dye with the particle size of 5 to 1,000 microns. The dye has the advantages of easy storage, no dust, environmental protection, easy dispersion, and easier product coloring.
Description
Technical field
The present invention relates to a kind of dyestuff post-treating method, is exactly specifically solvent dye to be prepared into to the preparation method of easy storage, dustless, easy disperse, hollow microparticle.
Background technology
What the production of solvent dye developed at home at present is very fast, the competition of its price, on the contrary, produce in the world the manufacturer of solvent dye: Beyer Co., Ltd, still solely embroider for one, the manufacturer of China also fails to cause the threat to them, its major cause: the solvent dye that Beyer Co., Ltd produces is the microparticle type, its main characteristics are: easily storage, easily dispersion, easy to clean, little, the dustproof environmental protection of loss are subjected to the plastics spinning manufacturer's of developed country welcome especially; The more important thing is because the space of the profit on sales of granulation solvent dye is more considerable.And the solvent dye of domestic production all adopts traditional drying mode, product is all powdery, loss is large in preparation and use procedure, pollution is heavy, product is difficult for disperseing, the difficult storage, though low price, to focusing on very much the developed country of environmental protection, such product beyond affordability, also just mean that this series products of China is difficult to enter the market of developed country.
Situation for fear of domestic high-grade dyestuff low-end merchandising, research and development hollow microparticle solvent dye product becomes a kind of Times ' Demand, the invention provides the preparation method's of a kind of novel easy storage, dustless, easy disperse, hollow microparticle solvent dye lab scale achievement, get ready for Chinese hollow microparticle solvent dye enters developed country.
Summary of the invention
The objective of the invention is to develop the preparation method of a kind of easy storage, dustless, easy disperse, hollow microparticle solvent dye, it has broken through traditional drying and crushing (loss greatly, pollution is heavy, technique is backward), the preparation technology that makes new advances of exploitation, make that product reaches easy storage, easily disperses, dustless good result.
The technical solution used in the present invention is: the preparation method of a kind of easy storage, dustless, easy disperse, hollow microparticle solvent dye comprises following concrete steps:
(1) 0.5-6% that dyestuff filter cake and complexed surfactant is accounted for to dyestuff butt total mass by complexed surfactant puts in sanding-pan and roughly grinds; In the corase grind process, add the defoamer that accounts for dyestuff butt total mass 0.1-0.3%;
(2) material of having roughly ground is transferred in clarifixator and refines, make the dye granule particle diameter reach the 1-80 micron;
(3) material refined is transported to spray-drying tower by high-pressure pump and carries out spray drying granulation, obtain the hollow microparticle dyestuff of particle diameter 5-1000 micron.
Above-mentioned complexed surfactant is comprised of polyoxyethylene glycol (PEG) and polyvinylpyrrolidone (PVP), and proportioning is 0.1-0.6/0.9-0.4, and the molecular weight of B, polyoxyethylene glycol (PEG) is calculated as 500----20000 by the number of OH; Polyvinylpyrrolidone (PVP) molecular weight is 10000----1300000.
Described complexed surfactant accounts for dyestuff butt total mass and is preferably 0.5----2.5%.
Described defoamer is BD-306R.
The medium of milling used in described corase grind process is
0.5-2.5mm the zirconium white ball, preferably
1.5 zirconium white.
Beneficial effect of the present invention: the solvent dye of producing due to the present invention is hollow microparticle shape, can in storage process, not produce caking, has increased stability, therefore easily stores; Owing on production technique of the present invention, not having dust to produce, in use can not produce dust yet, therefore dustless, environmental protection, can not produce the dust injury to operator; Because the present invention uses complexed surfactant, both be conducive to the dispersion of dye granule, again easily be used medium and merge, therefore product of the present invention easily disperses, and is easier to color articles.
Embodiment
The preparation method of a kind of easy storage of the present invention, dustless, easy disperse, hollow microparticle solvent dye, concrete steps are as follows:
(1) dyestuff filter cake and complexed surfactant being accounted for to 2.5% of dyestuff butt total mass by complexed surfactant puts in sanding-pan and roughly grinds; In the corase grind process, add the defoamer that accounts for dyestuff butt total mass 0.1-0.3%; Complexed surfactant is comprised of polyoxyethylene glycol (PEG) and polyvinylpyrrolidone (PVP), and proportioning is 0.6/0.4, and the molecular weight of polyoxyethylene glycol (PEG) is calculated as 6000----90000 by the number of OH; Polyvinylpyrrolidone (PVP) molecular weight is 24000----58000; Defoamer is BD-306R.The medium of milling used in the corase grind process is
0.5-2.5mm zirconium white ball.
(2) material of having roughly ground is transferred in clarifixator and refines, make the dye granule particle diameter reach the 1-80 micron;
(3) material refined is transported to spray-drying tower by high-pressure pump and carries out spray drying granulation, obtain the hollow microparticle dyestuff of particle diameter 5-1000 micron.
