Abstract
The invention relates to a preparation method of an efficient emulsifying dispersion degreaser, which comprises the following steps: adding butyl oleate sodium sulfonate, alkyl polyoxyethylene derivative, polyoxyethylene-polyoxypropylene block copolymer, polyacrylamide and dioctyl sebacate into a flask provided with a stirrer, a thermometer and a reflux condensing tube; adding deionized water and fatty alcohol sulfate monoethanolamine salt; heating to 90 DEG C; feeding nitrogen for protection; stirring for 35-55min; then slowly dropwise adding sodium chlorite for about 2h; insulating for 2h, and then adding tannin, ethanol and lauryl alcohol polyoxyethylene ether phosphate; reacting for 6-9h; and cooling to room temperature to obtain the emulsifying dispersion degreaser. The emulsifying dispersion degreaser has very strong degreasing emulsification and anti-after-tack functions and is used for decontaminating and degreasing environment-friendly textiles during dyeing.
Description
Technical field
The present invention relates to a kind of textile auxiliary, particularly a kind of preparation method of efficient emulsion dispersion degreaser.
Background technology
At dyeing, terylene, polyester-cotton blend, washing the knitted cloths such as ammonia, is adopt cylindrical machine to carry out knitting forming mostly.In recent years, woven processing producer is in order to weave cotton cloth more efficiently and reduce costs, and most of producer can increase the use of finish and finish inferior greatly, and this can bring very large difficulty to dyeing and printing process undoubtedly.Dye-works often can run into the problem of look flower, color dot and the oil mark deoiled not to the utmost.If employing secondary operations, after namely first kiering is deoiled in the basic conditions, then Colour Difference, the advantage done like this be deoil clean, to shelter disease few, shortcoming is that energy consumption is large, and the process time is long, and cost is high.For this reason, generally the dyeing that deoils is adopted at present.But dyeing (PH is 4-4.5) must use under meta-acid condition owing to deoiling, this makes dye-works more and more higher to the requirement with bath degreaser, not only require low-consuming, efficiency of deoiling is high, also want that decontamination is strong, whiteness is high, capillary effect is good, dyeing light is bright-coloured, also will possess certain level-dyeing property simultaneously, foam is low, cylinder is less poor and environment-protecting asepsis.
At present, domestic degreaser all also exists such-and-such shortcoming: general decontamination ability of deoiling is strong, and emulsifying ability is poor again; Or greasy dirt has got off, bad the returning again of emulsification has been stained with on casing wall, and then returns again to be stained with above cloth and produce oil mark.Therefore, need to develop and a kind ofly both there is excellent emulsifying ability, solubilising, the detergency of dispersion and greasy dirt prevent back being stained with function, the decontamination degreaser of the slow dye level-dyeing property under hot conditions can be taken into account again, also want environment-protecting asepsis.
Summary of the invention
The object of the invention is to overcome the problems referred to above, provide a kind of efficient emulsion dispersion degreaser, it has the extremely strong emulsification and prevent back being stained with function and textile dyeing decontamination for environmental protection is deoiled of deoiling.
To achieve these goals, the present invention adopts following technical scheme: a kind of preparation method of efficient emulsion dispersion degreaser, by n butyl oleate sodium sulfonate, alkyl polyoxyethylene derivative, polyox-yethylene-polyoxypropylene block copolymer, polyacrylamide and di-n-octyl sebacate add into agitator is housed, in the flask of thermometer and reflux condensing tube, add deionized water and fatty alcohol sulfate single ethanol ammonium salt, be warming up to 90 DEG C, pass into nitrogen protection, stir 35-55min, then slowly sodium chlorite is instilled, about 2h dropwises, tannic acid is added after insulation 2h, ethanol, ethoxylated dodecyl alcohol phosphate, react 6-9h again, be cooled to room temperature, namely emulsion dispersion degreaser is obtained,
The concrete constituent content of gained emulsion dispersion degreaser is as follows with parts by weight:
N butyl oleate sodium sulfonate 20-30
Alkyl polyoxyethylene derivative 15-18
Polyox-yethylene-polyoxypropylene block copolymer 12-16
Sodium chlorite 3-7
Polyacrylamide 2-8
Fatty alcohol sulfate single ethanol ammonium salt 0.5-3
Tannic acid 4-8
Di-n-octyl sebacate 10-20
Ethoxylated dodecyl alcohol phosphate 2-5
Ethanol 30-50
Deionized water 80-100;
Described ethoxylated dodecyl alcohol phosphate generates ethoxylated dodecyl alcohol by fatty alcohol and reacting ethylene oxide, then with phosphorus pentoxide esterification, neutralize and get final product.
Further, described efficient emulsion dispersion degreaser in use dressing liquid pH value remain on 5-7 the best.
Beneficial effect: efficient emulsion dispersion degreaser of the present invention has the extremely strong emulsification and prevent back being stained with function of deoiling, particularly for a lot of spandex of some greasy dirts, terylene class stockinette, as coral fleece has, two-sided bullet, spandex fabric, spandex are many, and wire drawing oil on spandex is a lot, what have also contains silicone oil, can realize co-bathing dyeing by adding efficient emulsion dispersion degreaser of the present invention.
With polyster fibre, cotton fiber affinity interaction while that the present invention adopting detergent n butyl oleate sodium sulfonate to coordinate polyox-yethylene-polyoxypropylene block copolymer and di-n-octyl sebacate, phenyl ring under condition of heating rapidly and on polyster fibre, the occupy-place of carbon ester molecule chain bonding, by robbing an effect and strong hydrophilicity effect, greasy dirt molecule is forced down, this deoils to release dirty core.
The present invention adds non-ionic surface active agent ethoxylated dodecyl alcohol phosphate simultaneously preferably, and it is that emulsification deoils can the strongest raw material of function, and this non-ionic surface active agent is nontoxic without hormone effect, belongs to environment-friendly products; Simultaneously, it retains stronger detergency, still identical with polyoxyethylene nonylphenol ether, even better, be easy at high temperature combine with polyster fibre under the synergy of fatty alcohol sulfate single ethanol ammonium salt and be stained with crowded for soil molecules, improve detersive efficiency.
