Problems solved by technology

This type of detergent builder has some help in reducing the viscosity of ordinary laundry powder slurries, but not significantly; it is even worse in reducing the viscosity of soap-based laundry powder slurries
[0004] Patent CN101144053A describes a dispersant for reducing the viscosity and stabilizing effect of washing powder slurry. The dispersant is obtained by copolymerization of unsaturated organic acid and unsaturated polyether monomer. The viscosity of the slurry increases the stability of the system, but its impact on the washing performance of the detergent is unknown and needs further research
[0005] Patent CN100564504C describes a copolymer prepared by the copolymerization of monomer components containing alkylene imine unsaturated monomers and other monomers as a detergent builder. The copolymer shows good detergent build-up The effect can significantly improve the detergency and anti-repollution of the detergent, but the structure of the copolymer is relatively complex, the cost is high, and the application in the detergent may be limited. At the same time, its effect on the viscosity of the washing powder slurry The impact is unknown, and it cannot be used as a viscosity-reducing synergist for laundry detergent for the time being

Embodiment 1

[0040] Add 50g water and 100g acetone into a 500g reactor, stir, heat to reflux, and drop the following materials respectively: A1: 50g acrylic acid, 10g allyl polyoxyethylene ether (20EO), 10g lauryl acrylate, 2g allyl alcohol and 0.05g mixture of methylenebisacrylamide, dropwise time 180min; B1: 10g10% sodium persulfate aqueous solution, dropwise time 200min; C1: 20g10% sodium sulfite aqueous solution, dropwise time 170min. After the dropwise addition of material B1, continue to keep warm for 30 minutes, then add water while vacuuming to remove isopropanol, keep the vacuum degree higher than -0.09MPa, and add water to keep the system from being too viscous. When the quality of the distillate reaches 200g, stop vacuuming, add an appropriate amount of sodium hydroxide solution to adjust the pH value to 7.0, and add a certain amount of water to make the solid content of the material 40%, to obtain polymer 1.

Embodiment 2

[0042] Add 50g water and 100g isopropanol to a 500g reactor, stir, heat to reflux, and drop the following materials respectively: A2: 55g methacrylic acid, 10g methoxypolyethylene glycol methacrylate (30EO), 5g1 - a mixture of tetradecene, 3g of acrylamide and 1g of mercaptoethanol, the dropwise addition time is 180min; B2: 10g of 10% sodium persulfate aqueous solution, the dropwise addition time is 200min. After the addition of material B2, continue to keep warm for 30 minutes, then add water while vacuuming to remove isopropanol, keep the vacuum degree higher than -0.09MPa, and add water to keep the system from being too viscous. When the quality of the distillate reached 200g, the vacuum was stopped, an appropriate amount of sodium hydroxide solution was added to adjust the pH to 7.0, and a certain amount of water was added to make the solid content of the material 40%, and polymer 2 was obtained.

Embodiment 3

[0044] Add 100g of isopropanol to a 500g reactor, stir, heat to reflux, and drop the following materials respectively: A3: 50g methacrylic acid, 10g allyl polyoxyethylene ether (20EO), 20g styrene and 3g methylene The mixture of propylsulfonic acid, the dropping time is 180min; B3: 20g 3% benzoyl peroxide solution in isopropanol, the dropping time is 200min. After the addition of material B3, continue to keep warm for 30 minutes, then add water while vacuuming to remove isopropanol, keep the vacuum degree higher than -0.09MPa, and add water to keep the system from being too viscous. When the quality of the distillate reaches 200g, stop vacuuming, add an appropriate amount of sodium hydroxide solution to adjust the pH value to 7.0, and add a certain amount of water to make the solid content of the material 40%, to obtain polymer 3.

Abstract

The invention discloses washing powder and a soap powder viscosity reduction synergist. The soap powder viscosity reduction synergist is characterized by being an amphipathic polymer copolymerized by the following monomers under the action of assistants: (a) 10-90 percent of carbpxyl-containing unsaturated monomer and / or salts thereof; (b) 1-80 percent of polyether-containing chain segment unsaturated monomers; (c) 0-70 percent of hydrophobic group-containing unsaturated monomer; and (d) 0-50 percent of acid diffluent water-soluble unsaturated monomer, wherein the weight percentage summation of all monomers is 100 percent. The invention also discloses a detergent addictive and a detergent with the washing powder and the soap powder viscosity reduction synergist. The soap powder viscosity reduction synergist can play roles of reducing the viscosities of the washing powder and soap powder dusting slurry and improving the washing effect and the synergism, thereby meeting the demand of the current market.

Description

technical field [0001] The invention belongs to the technical field of synthesizing functional polymers in macromolecular chemistry, and in particular relates to a viscosity-reducing synergist for washing powder and soap powder, and a detergent additive and detergent containing the viscosity-reducing synergist. Background technique [0002] Due to the importance of environmental protection, phosphorus-free, concentrated, and soap-based detergents have become the mainstream direction of detergent development, but they are still restricted by some factors. Phosphorus-free detergents perform poorly in terms of decontamination and anti-ash deposition, and need to use more efficient detergent boosters to promote their development; concentrated detergents also have a greater demand for high-efficiency detergent boosters; and soap-based washing Agents, especially soap-based detergents, have the problem of sticky slurry during the powder spraying process, and the washing performance...
