Abstract

The invention belongs to the technical field of environment-friendly chemicals, particularly relates to an environment-friendly chloride-free snow melt antifreezing agent and further discloses a preparation method thereof. The environment-friendly chloride-free snow melt antifreezing agent is prepared from the following raw materials: glycol, diglycerol, glyceryl triacetate, white sugar, zinc acetate, sodium polyacrylate, ethyl alcohol and water, and is free from any chlorine salt ingredient; the adopted raw materials are completely safe and toxic ingredients, safe and environmentally friendly, and completely conforms to the environment-friendly requirement. The environment-friendly chloride-free snow melt antifreezing agent has average product freezing point lower than 18 DEG C below zero, the snow-melting and deicing capability is near or even higher than the performance of existing sodium chloride, and the snow-melting performance is relatively ideal.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly chemicals, in particular to an environment-friendly chlorine-free snow-melting antifreeze, and further discloses a preparation method thereof. Background technique [0002] Deicing agent, as the name suggests, its function is to melt snow and ice. Snow melting agent, also known as deicing salt and road antifreeze, is mainly used in winter airports, highways, squares, parking lots, railways, urban streets, etc. to melt ice, melt snow and prevent freezing. Some snow melting agents can also be used for construction Quick-thawing agent and antifreeze admixture for ice and snow melting in engineering construction in winter. This requires that the deicing agent cannot damage roads, concrete components, and bridge facilities, nor can it damage flowers, trees, crops, animals, or harm people. [0003] At present, there are many types of deicing agents developed in my country, which are divid...
