Abstract
The invention discloses a preparation method for an efficient low-foaming detergent. The preparation method comprises steps as follows: synthesizing to obtain hydroxymethyl crylic acid, maleic anhydride and acrylamide copolymer; compounding the copolymer with the efficient low-foaming detergent so as to obtain an optimal detergent product containing 20% of solid. The efficient low-foaming detergent prepared by the preparation method disclosed by the invention has the advantages of being less in foam, fast in foam removing, high in cleaning performance, and strong in flooding resistance; and the efficient low-foaming detergent can be widely used as soaping for wool textiles, cotton textiles, fiber products, silk products and chemical fiber products and the like.
Description
Technical field:
The present invention relates to a kind of High Efficiency and Low Foam Detergent, particularly a kind of preparation method of new and effective low bubble detergent.
Background technology:
Detergent is the important after treatment aids of printing and dyeing mill.At present, used detergent is of a great variety on the market, but foam is more mostly, the generation of foam not only can cause the waste of raw material, and the pollution of water resources is run off, and spot that also may be a large amount of is detained, is piled up at cloth, cause the increase of energy consumption, make troubles to production operation.Especially on the production line that on-line velocity is high, the impact of foam is more serious.The foam that adopts low bubble nonionogenic tenside or defoamer to reduce and eliminate in the production process is the method for commonly using, yet the nonionogenic tenside price is generally higher, has limited its use range; Use the defoamer froth breaking, generally need to just can obtain preferably defoaming effect under higher defoamer massfraction, production cost increases, and also may produce the silicon spot, affects washing effect.This research is by great many of experiments, compositely prepares a kind of efficient, low bubble detergent.
Summary of the invention:
Goal of the invention: for the defective that prior art exists, it is few to the invention provides a kind of foam, and bubble burst is fast, the preparation method of washing excellent property, the strong detergent of removal loose colour ability.
Technical scheme: for achieving the above object, the present invention by the following technical solutions:
A kind of preparation of High Efficiency and Low Foam Detergent:
1) methylol vinylformic acid, the preparation of maleic anhydride and acrylamide copolymer: a, in being furnished with the 1000ml four-hole boiling flask of thermometer, reflux condensing tube, two dropping funnels, the maleic anhydride and the water that add metering, be warming up to 50 ~ 80 ℃, stirring and dissolving, the sodium hydroxide solution of adding 25% is regulated PH to 5.5 ~ 7.0, gets a liquid; B, take by weighing methylol vinylformic acid and the Sodium Persulfate of metering, be dissolved in suitable quantity of water, and regulate PH to 3.5 ~ 4.5 with 25% sodium hydroxide solution, get b liquid; C, take by weighing the acrylamide of metering, drip simultaneously in the people a liquid with b liquid, 80 ~ 110 ℃ of control temperature, time for adding 3 ~ 6 hours drips and finishes, and reacts under the reflux state 10 ~ 16 hours, is cooled to 50 ℃, obtains yellow sticky polymers product.
2) High Efficiency and Low Foam Detergent is composite: A, in the reactor of 1000ml, add successively fatty alcohol-polyoxyethylene ether-15, and water, be warming up to 30 ~ 60 ℃, stirred 0.5 ~ 1 hour, make its dissolving.Add successively in B, the solution that obtains to steps A, poly-(4 monohydroxy tetramethylenes 1, the 2-dicarboxylic acid) (CP2), methylol vinylformic acid, maleic anhydride and acrylamide copolymer, fatty alcohol-polyoxyethylene ether-9 sodium sulfate adds quantitative water again, stirred 0.5 ~ 2 hour at 50 ~ 80 ℃, make solid content and be 20% optimization detergent product.Raw materials used mass fraction is:
Fatty alcohol-polyoxyethylene ether-15:5 ~ 20 part
Poly-(4 monohydroxy tetramethylenes 1,2-dicarboxylic acid): 50 ~ 200 parts
Methylol vinylformic acid, maleic anhydride and acrylamide copolymer: 10 ~ 30 parts
Fatty alcohol-polyoxyethylene ether-9 sodium sulfate: 10 ~ 30 parts
Water: an amount of
In the preparation of described High Efficiency and Low Foam Detergent, fatty alcohol-polyoxyethylene ether-15: poly-(4 monohydroxy tetramethylenes 1, the 2-dicarboxylic acid): methylol vinylformic acid, maleic anhydride and acrylamide copolymer: the mass ratio of fatty alcohol-polyoxyethylene ether-9 sodium sulfate is 1:10 ~ 40:1 ~ 10:1 ~ 10.
According to above technical scheme, can realize following beneficial effect: compared with prior art, the present invention has the following advantages: High Efficiency and Low Foam Detergent that the present invention obtains: it is few to have a foam, bubble burst is fast, the washing excellent property, remove the advantages such as the loose colour ability is strong, and can be widely used in wool spinning, cotton, fiber crops, silk, the fabrics such as chemical fibre are used as soaping agent.
