Embodiment 1
[0008] Embodiment 1: Mass%
[0009] Fatty alcohol polyoxyethylene ether (AEO-9) 1.0~4.0%
[0010] Lauryl amphopropyl sulfonate 0.2~0.6%
[0011] Ethanol 6~15%
[0012] Glycerol 6~20%
[0013] Triethanolamine 0.2~2.0%
[0014] Isopropanol 1.0~5%
[0015] Polyethylene glycol (800) 0.1~0.6%
[0016] Deionized water ~100%
[0017] Take measured deionized water into the reaction kettle, add 0.2% polymer film-forming agent polyethylene glycol (800) and heat to 40°C and stir to dissolve, then add 2.0% fatty alcohol polyoxyethylene ether (AEO-9) in sequence Nonionic surfactant, 0.3% lauryl amphopropyl sulfonate cationic surfactant, add 8% ethanol, 10% glycerol and 2.0% isopropanol, finally add 0.5% acidity regulator triethanolamine , adjust the pH of the solution to be neutral or weakly acidic, stir evenly and cool down to room temperature to obtain the glass antifogging agent solution.
Embodiment 2
[0018] Embodiment 2: Mass%
[0019] Nonylphenol polyoxyethylene ether (OP-10) 1~4%
[0020] Coco alkyl trimethyl ammonium chloride 0.2~0.6%
[0021] Ethanol 6~15%
[0022] Glycerol 6~20%
[0023] Triethanolamine 0.5~1.5%
[0024] Isopropanol 1~5%
[0025] Polyvinylpyrrolidone 0.1~0.6%
[0026] Deionized water ~100%
[0027] Take measured deionized water into the reaction kettle, add 0.2% polymer film-forming agent polyvinylpyrrolidone, heat to 40°C and stir to dissolve, then add 2% nonylphenol polyoxyethylene ether nonionic surfactant in turn, 0.2% cationic surfactant of coconut oil alkyltrimethylammonium chloride, add 8% ethanol, 10% glycerol and 2% isopropanol, and finally add 1% acidity regulator triethanolamine to adjust the pH of the solution It is neutral or weakly acidic, stir evenly and cool down to room temperature to get the glass antifogging agent solution.
