[0037] 1. Examples and Comparative Examples

[0038] The material list of the embodiments, comparative examples and representative multifunctional scouring agents on the market is shown in Table 2.

[0039] Table 2

[0040]

[0041] Representative multifunctional scouring agent 1 on the market: maleic acid-acrylate polymer; Representative multifunctional scouring agent 2 on the market: isooctyl alcohol polyoxyethylene ether phosphate.

[0042] Preparation method: Heat the water to 55°C, add alkyl polyglycoside, and stir for 15 minutes until it is completely uniform; add fatty alcohol polyoxyethylene ether carboxylic acid, and stir for 15 minutes until it is completely uniform; add fatty amine polyoxyethylene ether, and stir for 15 minutes until it is completely uniform; add ethylenediaminetetraacetic acid, and stir for 15 minutes until it is completely uniform; add sodium ethylenediamine di-o-phenylacetate, and stir for 15 minutes until it is completely uniform; add sodium chloride, and stir for 15 minutes until it is completely uniform; add magnesium chloride, and stir for 15 minutes until it is completely uniform.

[0043] 2. Roche foam test

[0044] Formula: Scouring agent 2g / L; Process: Test method refers to ASTM D1173-07.

[0045] Evaluation explanation: The higher the initial foam height (s / cm) of Roche foaming, the longer the complete defoaming time is, which means that the additive foam is high and difficult to defoam. The results are shown in Table 3.

[0046] Table 3

[0047]

[0048]

[0049] As can be seen from the above table, the foam ratio of the Luoshi foaming in Examples 1-3 is lower and can meet the requirements of the machine cylinder treatment.

[0050] Comparative Examples 1 and 5 change the dosage relationship of the nonionic surfactant, the chelating agent and the salt, and the foam of the Roche foaming increases.

[0051] Comparative Example 2 did not use stearic acid polyoxyethylene ether carboxylic acid and ethylenediaminetetraacetic acid, and the foam of its Roche foaming increased.

[0052] Comparative Example 3 changes the dosage of the nonionic surfactant, and the foam of the Roche foaming increases.

[0053] In Comparative Example 4, the dosage of the chelating agent was changed, and the foam of the Roche foaming was increased.

[0054] 3. Penetration performance test

[0055] Working solution 1: scouring agent 3g / L, working solution 2: scouring agent 3g / L + NaOH 30g / L.

[0056] Process: Test method refer to GB / T 11983-2008.

[0057] Evaluation explanation: The shorter the penetration force (S), that is, the shorter the time it takes for the canvas piece to fall, the better the penetration effect of the additive. The results are shown in Table 4.

[0058] Table 4

[0059]

[0060]

[0061] It can be seen from the above table that Examples 1-3 have short penetration times and better penetration performance.

[0062] Comparative Examples 1 and 5 change the dosage relationship of the nonionic surfactant, the chelating agent and the salt, and their penetration performance is poor.

[0063] Comparative Example 2 did not use stearic acid polyoxyethylene ether carboxylic acid and ethylenediaminetetraacetic acid, and its permeability was poor.

[0064] Comparative Example 3 changes the dosage of the nonionic surfactant, and its penetration performance is poor.

[0065] Comparative Example 4 changes the dosage of the chelating agent, and its permeability is poor.

[0066] 4. Scouring capillary effect performance test

[0067] Formula: NaOH 15g / L+ scouring agent Xg / L, X is 0.5, 1 and 2; fabric: 20×16 / 128×60 cotton woven grey cloth 5g; bath ratio: 1:10; steel balls: 10 pieces / cup.

[0068] Process: 98℃×60min, test 30min scouring effect.

[0069] Evaluation explanation: The higher the capillary effect value of cotton fabric at 30 minutes, the better the capillary effect of the scouring agent. The results are shown in Table 5.

[0070] Table 5

[0071]

[0072]

[0073] It can be seen from the above table that Examples 1-3 have high capillary effects and excellent scouring capillary effects.

[0074] Comparative Examples 1 and 5 change the dosage relationship of the nonionic surfactant, the chelating agent and the salt, and their capillary effects are low.

[0075] Comparative Example 2 does not use stearic acid polyoxyethylene ether carboxylic acid and ethylenediaminetetraacetic acid, and its capillary efficiency is low.

[0076] Comparative Example 3 changes the dosage of the nonionic surfactant, and its capillary effect is low.

[0077] Comparative Example 4 changes the dosage of the chelating agent, and its capillary efficiency is low.

[0078] 5. Hydrogen peroxide stability test

[0079] Formula: hydrogen peroxide 2g / l + iron ion 2.5ppm + scouring agent 2g / L.

[0080] Process: 98℃×60min, test the decomposition rate of hydrogen peroxide in different time periods.

[0081] Evaluation explanation: The lower the hydrogen peroxide decomposition rate of the additive, the better the additive controls the decomposition of hydrogen peroxide and the better the stability of hydrogen peroxide. The results are shown in Table 6.

[0082] Table 6

[0083]

[0084]

[0085] It can be seen from the above table that Examples 1-3 have low decomposition rates and better hydrogen peroxide stability.

[0086] Comparative Examples 1 and 5 change the dosage relationship of the nonionic surfactant, the chelating agent and the salt, and the stability of the hydrogen peroxide is poor.

[0087] Comparative Example 2 does not use stearic acid polyoxyethylene ether carboxylic acid and ethylenediaminetetraacetic acid, and its hydrogen peroxide stability is poor.

[0088] Comparative Example 3 changes the dosage of the nonionic surfactant, and its hydrogen peroxide stability is poor.

[0089] In Comparative Example 4, the dosage of the chelating agent was changed, and the stability of hydrogen peroxide was poor.
