Embodiment 1

[0087] Example 1 Preparation of Anionic Waterborne Polyurethane Dispersion-1

[0088] The preparation of anionic waterborne polyurethane dispersion-1 in this example includes the following steps: add 150g CMA-654, 15g 1,4-butanediol, 12g DMPA into a four-necked flask, stir at 65°C for 8min, cool down to 45°C and add 120g HMDI reaction, react until the NCO content reaches the theoretical value of 2.20wt%, stop the reaction; cool down to 45°C, dissolve in 160g of acetone solvent, mix for 13min, add 9g of triethylamine and react for 5 minutes to neutralize to pH 7.5, 40 After the reaction was continued for 28 minutes under the condition of ℃, 559 g of water was added under the condition of shear dispersion, and then the acetone was removed by distillation under reduced pressure to obtain anionic aqueous polyurethane dispersion-1 with a solid content of about 35 wt%, and a particle size of 50 nm.

Embodiment 2

[0089] Example 2 Preparation of Anionic Waterborne Polyurethane Dispersion-2

[0090] The preparation of the anionic aqueous polyurethane dispersion-2 in this example includes the following steps: add 280g of CMA-654, 0.4g of 1,4-butanediol, and 29g of DMPA into a four-neck flask, stir at 75°C for 12min, cool down to 55°C and add 104g HMDI reaction, react until the NCO content reaches the theoretical value of 2.08wt%, stop the reaction; cool down to 35°C, dissolve in 230g of acetone solvent, mix for 15min, add 21.86g of triethylamine and react for 4 minutes to neutralize to pH 8.5, After continuing the reaction at 45°C for 30 minutes, 767 g of water was added under shear dispersion conditions, and then the acetone was removed by distillation under reduced pressure to obtain anionic aqueous polyurethane dispersion-2 with a solid content of about 35 wt % and a particle size of 40 nm.

Embodiment 3-7

[0091] Example 3-7 Preparation of multifunctional laundry detergent composition

[0092] The formula of embodiment 3-7 is as shown in table 1. Prepare the multifunctional laundry detergent composition according to the following method: take each component according to the formula ratio in Table 1, add each component successively under stirring at 500r / min at room temperature, and adjust the pH value to 7.5-8.5, stir for 15- 30 minutes until completely dispersed.

[0093] The formula (mass unit: g) of table 1 embodiment 3-7 and comparative example 1-5

Abstract

The invention provides a multifunctional laundry detergent composition with both color fixing and bacteriostatic effects, and a preparation method and application thereof. The multifunctional laundry detergent composition comprises the following components: 0.1-10 parts by weight of anionic aqueous polyurethane dispersion; 0.2-2 parts by weight of pyridone ethanolamine salt; 0-20 parts by weight of anionic surfactant; ~20 parts by weight; water, the amount of which is based on the sum of the parts by weight of the components in the multifunctional laundry detergent composition is 100 parts by weight. In the invention, the anionic water-based polyurethane dispersion and the pyridone ethanolamine salt are compounded, and the experimental results show that the two have a synergistic effect after compounding, and significantly improve the color protection, anti-cross-color, anti-static and anti-light. Color fading and antibacterial and so on.

Description

technical field [0001] The invention belongs to the field of macromolecules, and in particular relates to a multi-functional laundry detergent composition having both color-fixing and antibacterial effects, a preparation method and application thereof. Background technique [0002] The following problems are often encountered in the daily washing process: For example, after repeated washings, dark-colored clothes often have fading and whitening phenomena, and light-colored clothes and dark-colored clothes are easily washed together to cause dye transfer and cross-color, etc. . Based on the above problems, people have more and more demands on the color protection of colored clothes, the anti-dye cross-color of light-colored clothes, the mixed washing of clothes, the sterilizing function of clothes and so on. [0003] In order to solve the above problems, the patent document CN101914857A discloses: a new cationic reactive polyurethane film-forming color-fixing agent with good...
