Embodiment 1
[0015] The materials will be weighed according to the dosage ratio (mass percentage), according to glycerol 20%, ethylene glycol 15%, water 38%, alkylphenol polyoxyethylene ether 2%, sodium formate 15%, potassium acetate 3%, sodium phosphate Put 4% sodium tetraborate and 3% sodium tetraborate into the reaction kettle in turn, stir evenly at 40°C, continue stirring for 30 minutes after cooling to room temperature, and fill the product to obtain a non-chlorine liquid environment-friendly deicing agent.
Embodiment 2
[0017] The materials will be weighed according to the dosage ratio (mass percentage), according to glycerol 18%, ethylene glycol 15%, water 35%, alkylphenol polyoxyethylene ether 1%, sodium formate 20%, potassium acetate 4%, sodium phosphate Put 5% and 2% sodium tetraborate into the reaction kettle in turn, stir evenly at 40°C, continue to stir for 30 minutes after cooling to room temperature, and fill the product to obtain a non-chlorine liquid environment-friendly deicing agent.
[0018] Implementation Effect
[0019] 1. The freezing point of the non-chlorine liquid environment-friendly deicing agent of the present invention, the relative snow-melting and deicing ability, and the test method of carbon steel corrosion rate are carried out with reference to DB11 / T 161-2012 deicing agent. The non-chlorine liquid environment-friendly deicing agents of Examples 1 and 2 were tested, and the results are shown in Table 1.
