Embodiment 1
[0025] According to the mass ratio, it is fatty alcohol polyoxyethylene ether sodium sulfate (AES) 5-7%, sodium dodecyl sulfate (K12) 1%, sodium dodecylbenzenesulfonate (DBS) 3.5%, tea saponin 0.15% %, disodium ethylenediaminetetraacetic acid (EDTA) 2%, modified nano-bentonite 1.5% and the rest of the water to prepare raw materials. First add fatty alcohol polyoxyethylene ether sodium sulfate (AES) into an appropriate amount of water, heat and stir evenly in a water bath at a temperature of 30°C-50°C; then add sodium lauryl sulfate (K12), dodecylbenzene Sodium sulfonate (DBS), continue to stir until all materials are completely dissolved, and finally add tea saponin, disodium ethylenediaminetetraacetic acid (EDTA), modified nano-bentonite and the rest of the water.
Embodiment 2
[0027] According to the mass ratio, it is fatty alcohol polyoxyethylene ether sodium sulfate (AES) 5.5-7.5%, sodium dodecyl sulfate (K12) 2%, sodium dodecylbenzenesulfonate (DBS) 2.5%, tea saponin 0.3 %, disodium ethylenediaminetetraacetic acid (EDTA) 2.5%, modified nano-bentonite 2% and the rest of the water to prepare raw materials. First add fatty alcohol polyoxyethylene ether sodium sulfate (AES) into an appropriate amount of water, heat and stir evenly in a water bath at a temperature of 30°C-50°C; then add sodium lauryl sulfate (K12), dodecylbenzene Sodium sulfonate (DBS), continue to stir until all materials are completely dissolved, and finally add tea saponin, disodium ethylenediaminetetraacetic acid (EDTA), modified nano-bentonite and the rest of the water.
Embodiment 3
[0029] According to the mass ratio, it is fatty alcohol polyoxyethylene ether sodium sulfate (AES) 7-8%, sodium dodecyl sulfate (K12) 3%, sodium dodecylbenzenesulfonate (DBS) 1.5%, tea saponin 0.45% %, disodium ethylenediaminetetraacetic acid (EDTA) 3%, modified nano-bentonite 2.5% and the rest of the water to prepare raw materials. First add fatty alcohol polyoxyethylene ether sodium sulfate (AES) into an appropriate amount of water, heat and stir evenly in a water bath at a temperature of 30°C-50°C; then add sodium lauryl sulfate (K12), dodecylbenzene Sodium sulfonate (DBS), continue to stir until all materials are completely dissolved, and finally add tea saponin, disodium ethylenediaminetetraacetic acid (EDTA), modified nano-bentonite and the rest of the water.
