Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of daily chemicals, and relates to a water scale resistant commercial laundry detergent. BACKGROUND

[0002] In modern laundry services, laundry detergent, as a key washing medium, has a wide application prospect. Traditional laundry detergent is generally a household laundry detergent, which is generally composed of multiple surfactants and enzyme preparations. Because of the appearance phase stability of the laundry detergent, it is difficult to be compatible with softening agent and anti-redeposition agent. If the water hardness is greater than or equal to 80 ppm and the softening agent and dispersing agent are lacking, even if the hard water resistant surfactant is used, the decontamination ability will be significantly reduced. If the anti-redeposition agent is lacking, the stain anti-redeposition is obviously insufficient, and long-term use will cause scale accumulation in the washing machine, which is harmful to the equipment. The washing effect of commercial laundry detergent is required to be high, and the washing of hotel linen such as towels, bed sheets, work clothes and restaurant tablecloths will have stubborn stains. The cleaning effect of conventional laundry detergent is not obvious, and high-temperature cleaning may cause a large cost expenditure, which is obviously not economical. Therefore, it is necessary to further optimize and improve the formula structure of the household laundry detergent to make up for the shortcomings of traditional laundry detergent to fabrics, equipment and environment.

2. The scale-resistant commercial laundry detergent according to claim 1, characterized in that: The polyether-modified silicone oil is a polyether-modified silicone oil coated with Pluronic F-127; the preparation method of the polyether-modified silicone oil coated with Pluronic F-127 includes the following steps: A1. Pluronic F-127, polyvinylpyrrolidone, and purified water were mixed at a relatively low temperature to obtain a shell solution; A2. Add polyether-modified silicone oil dropwise to the shell solution, shear at high speed, and then let it stand at room temperature to obtain the product.

3. The scale-resistant commercial laundry detergent according to claim 2, characterized in that: The mass ratio of Pluronic F-127, polyvinylpyrrolidone, polyether-modified silicone oil, and purified water is 0.3-0.4:0.5-0.6:0.5-0.6:5.1-5.

5.

4. The scale-resistant commercial laundry detergent according to claim 2, characterized in that: The mixing at a lower temperature mentioned in step A1 refers to stirring at 100-200 rpm at 14-18°C until completely dissolved.

5. A scale-resistant commercial laundry detergent according to claim 2, characterized in that: The dripping rate in step A2 is 1-3 drops / s; the high-speed shearing refers to stirring at 8000-12000 rpm for 10-20 minutes.

6. A method for preparing a scale-resistant commercial laundry detergent as described in any one of claims 1-5, characterized in that: The preparation method of the commercial laundry detergent includes the following steps: B1. Add purified water to the reaction vessel, heat it, and then add urea, sodium chloride, sodium hydroxide, water softener, and isothiazolinone in sequence. Mix them to obtain a premixed aqueous phase. B2. After adding fatty alcohol polyoxyethylene ether, fatty alcohol polyoxyethylene ether sodium sulfate and sodium dodecyl sulfonate to the premixed aqueous phase, stir once, then add sodium coconut oil and stir a second time to obtain material one. B3. Add polyacrylate and cellulose ether to material one, mix, and obtain material two; B4. Add polyether-modified silicone oil to material 2, mix, filter, and the product is obtained.

7. The method for preparing a scale-resistant commercial laundry detergent according to claim 6, characterized in that: The heating mentioned in step B1 refers to heating to 30-40°C; mixing refers to stirring at 30-70 rpm until completely dissolved.

8. The method for preparing a scale-resistant commercial laundry detergent according to claim 6, characterized in that: The first stirring mentioned in step B2 refers to stirring at 60-100 rpm for 15-25 minutes; the second stirring refers to stirring at 80-120 rpm for 10-20 minutes.

9. The method for preparing a scale-resistant commercial laundry detergent according to claim 6, characterized in that: The mixing mentioned in step B3 refers to stirring at 40-80 rpm for 10-20 minutes.

10. The method for preparing a scale-resistant commercial laundry detergent according to claim 6, characterized in that: The mixing mentioned in step B4 refers to stirring at 30-50 rpm for 8-12 minutes.
