Description
Technical Field

Background
The chelating agent is a main component in the synthetic detergent, plays a great role in improving the cleaning effect of the surfactant and other components in the cleaning agent, and generally accounts for 5-10% in the formula of the synthetic cleaning agent. The chelating agent has the most basic functions of reducing the hardness of the washing water, reacting with metal ions in the water and preventing the metal ions from acting with a surfactant, so that the dirt-removing capacity in a single-cycle washing process and the cycle effect of multiple times of washing are enhanced; the chelating agent also has the ability to retain and provide alkalinity, maintain the detergent solution at 9.5-10.5, and have a certain buffering capacity to ensure that other components can disperse the soil and control the dissolved soil from being deposited.
Chinese patent CN103642603B discloses an oxygen bleaching washing powder and a preparation method thereof, wherein the oxygen bleaching washing powder comprises the following components in percentage by mass: 75-80% of sodium percarbonate, 5-8% of sodium tripolyphosphate, 5-8% of sodium alkyl benzene sulfonate, 5-8% of sodium metasilicate, 2-3% of sodium carboxymethyl cellulose, 1-3% of fatty alcohol-polyoxyethylene ether and 0.1-0.2% of fluorescent whitening agent. Sodium tripolyphosphate in the formula is a chelating agent with excellent performance and high cost performance, but sodium tripolyphosphate can be hydrolyzed to generate orthophosphate after entering an environmental water body, and the orthophosphate is a necessary nutrient substance for growth and reproduction of various life forms, so that eutrophication of a large-area water body can be caused, a large amount of algae can be reproduced, and the water quality is deteriorated.
Chinese patent CN108085162B discloses a green environment-friendly detergent, which comprises the following components in parts by weight: 40-60 parts of water; 0.2-0.8 part of sodium citrate; 1-3 parts of tea saponin; 0.2-0.8 part of 2, 5-dimethylbenzoxazole; 1-5 parts of 1, 2-propylene glycol; 1-3 parts of triethanolamine; 4-8 parts of alpha-hexadecyl-omega-hydroxy-poly (oxyethylene); 3-7 parts of sodium laureth sulfate; 0.5-1.5 parts of N, N-bis (2-hydroxyethyl) dodecyl amide; 3-7 parts of dodecyl glucoside; 1-3 parts of sodium xylene sulfonate. The sodium citrate in the formula is a chelating agent with good biodegradability and safety, but has high cost and low chelating force to heavy metal ions, and limits the use of a large amount of sodium citrate in a synthetic detergent.

preparation of hard water according to the method of preparation of water with known calcium hardness as a surfactant (GB/T6367-2012), 16.7g of anhydrous calcium chloride and 24.7g of magnesium sulfate are weighed to prepare 10L of hard water with the concentration of about 2500mg/L, the hard water is diluted into water with different hardness when in use to prepare water with different hardness, and then the alkaline cleaning agent is diluted to the use concentration by using the hard water to test the hard water resistance of the alkaline cleaning agent.
| Hardness of | 250mg/L | 375mg/L | 500mg/L | 625mg/L |
| Example 1 | Transparent and without precipitate | Transparent and without precipitate | Transparent and without precipitate | Transparent and without precipitate |
| Example 2 | Transparent and without precipitate | Transparent and without precipitate | Transparent and without precipitate | Transparent and without precipitate |
| Example 3 | Transparent and without precipitate | Transparent and without precipitate | Transparent and without precipitate | Transparent and without precipitate |
| Example 4 | Is transparent,No precipitation | Transparent and without precipitate | Transparent and without precipitate | Transparent and without precipitate |
| Comparative example 1 | Turbidity and sediment | Turbidity and sediment | Turbidity and sediment | Turbidity and sediment |
| Comparative example 2 | Turbidity and no precipitate | Turbidity and sediment | Turbidity and sediment | Turbidity and sediment |
The hard water resistance results of examples 1 to 4 and comparative test examples show that the glass cups of examples 1 to 4 can resist hard water with hardness of 250mg/L to 625mg/L when the diluted concentration of the high-efficiency cleaning agent is 4%, and the hard water resistance of the comparative example is poor, which is mainly because the chelating agent is absent in the comparative example, and the metal ions in the water interfere with the cleaning capability of the surfactant.
(2) And (3) determining the detergency:
selecting 50 glass cups with the same specification as cleaning test pieces, 10 glass cups in each group, averagely dividing the glass cups into 5 groups, marking as a test piece group 1-5, drying the test pieces in an oven at the temperature of 85 ℃ to constant weight, weighing the test pieces, and marking as m0(accurate to 0.0001g), then coating the prepared dirt liquid on a glass sample sheet, controlling the coating amount to be 2-2.5g, then putting the glass sample sheet into a thermostat at 85 ℃ for drying for 1h, taking out and weighing, and recording the weight as m1(to an accuracy of 0.0001g), the scale solution was prepared by placing 0.25g of carbon black, 20.0g of syrup, 20.0g of tea, 20.0g of paraffin and 20.0g of soy sauce in a containerStirring in a beaker to obtain a viscous liquid.
Taking 50 400mL beakers, and marking the beakers as 1-50, pouring 300g of water and 10g of antibacterial self-cleaning agent for the glass prepared in example 1 into No. 1-10 beakers, pouring 300g of water and 10g of antibacterial self-cleaning agent for the glass prepared in example 2 into No. 11-20 beakers, and so on, pouring 300g of water and 10g of antibacterial self-cleaning agent for the glass prepared in comparative example into No. 41-50 beakers, sequentially putting 10 glass cups in a sample group 1 into the beakers 1-10, sequentially putting 10 glass cups in a sample group 2 into the beakers 11-20 under the condition of water bath at 25 ℃, and so on, sequentially putting 10 glass cups in a sample group 5 into the beakers 41-50, fully immersing the surface-stained part of each sample in the cleaning agent for 1min, washing for 1.5min at a speed of 40r/min, washing in 300mL distilled water for 30s, placing in a tray, oven drying at 85 deg.C for 1.5h, cooling at room temperature for 20min, weighing, and recording as m2(to the nearest 0.0001g),
the detergency was calculated as follows: f (%) ═ m1-m2)/(m1-m0) X 100%, the detergency of the antibacterial self-cleaning agent for each group of glasses was averaged and the test results are shown in table 1.
And (3) testing the number of fine scratches:
the surfaces of the glasses after the above-mentioned detergency test were observed, and the number of scratches of each set of examples and comparative examples was recorded, and the test results are shown in the following table.
The results of the effect test of the antibacterial self-cleaning detergent for glasses prepared in examples 1 to 4 and comparative examples 1 to 2 are as follows:
| test items | f(％) | Number of scratched cups |
| Example 1 | 99.65 | 0 |
| Example 2 | 97.32 | 0 |
| Example 3 | 99.76 | 1 |
| Example 4 | 99.88 | 0 |
| Comparative example 1 | 80.52 | 3 |
| Comparative example 2 | 83.76 | 3 |
According to the embodiments 1-4, the antibacterial self-cleaning agent for the glass cup prepared by the invention has good decontamination effect, and has certain protection capability on the surface of the glass cup in the use process, while the decontamination capability of the comparative example is greatly reduced, and certain damage is caused on the surface of the glass in the cleaning process.
