▎ 摘  要

NOVELTY - Ultra-low temperature composite antifreeze agent comprises 10-20 pts. wt. hydrated calcium silicate, 2-8 pts. wt. sodium nitrite, 3-6 pts. wt. sodium sulfate, 2-10 pts. wt. graphene oxide, 5-12 pts. wt. dicyclohexylcarbodiimide, 1-5 pts. wt. alkyl organic amine, 0.2-1 pts. wt. triterpenoid saponin, 2-5 pts. wt. initiator, 6-12 pts. wt. acrylamide, 0.2-1 pts. wt. surfactant, 2-8 pts. wt. calcium lignosulfonate, 3-8 pts. wt. sulfamate, 8-10 pts. wt. sodium gluconate, 0.2-2 pts. wt. silane coupling agent, 120-35 pts. wt. vinyl acetate-ethylene emulsion DA10, 0.1-1 pts. wt. formic acid and 20-30 pts. wt. ethanol. USE - The antifreeze agent is useful for concrete (claimed). ADVANTAGE - The antifreeze agent accelerates the setting speed of concrete and improves strength and durability of concrete at -20 degrees C.
