Abstract

The invention relates to a preparation method of a low corrosivity snow melting agent, belonging to the technical field of preparation of snow melting agents. The preparation method comprises the steps of first, collecting waste animal fat, putting the animal fat in a high-temperature high-humidity environment, performing rancidification of fat under the role of organism, enzyme and oxygen in airso as to obtain rancidity substances rich in fat and carboxylic acid, then, mixing fruits rich in organic carboxylic acid and starch and konjac and then fermenting, decomposing under the role of lactobacillus in yoghurt and bacillus subtilis so as to obtain a fermentation liquid rich in fruit acid and lactic acid. According to the preparation method, the raw material oyster shell is calcined at high temperature and then is reacted with water, so as to generate clear limewater rich in calcium ions, finally, the rancidity substances, fermentation liquid and the limewater are carried out bendingreaction, so as to obtain a reaction product, and the reaction product is mixed with propylene glycol so as to obtain the low corrosivity snow melting agent. The snow melting agent prepared by the method has low corrosivity, has high ice melting capability, and damages plants and environment slightly, thereby having a broad application prospect.

Description

technical field [0001] The invention relates to a preparation method of a low-corrosion snow-melting agent, belonging to the technical field of snow-melting agent preparation. Background technique [0002] 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 remove snow and prevent freezing. Its ingredients are sodium chloride, calcium chloride, magnesium chloride, etc. Salt-based. Due to the advantages of convenient use and moderate price, deicing agents are not only widely used in large cities, but also gradually tend to be used in large quantities in many small and medium-sized cities. However, the most commonly used deicing agents are mostly chlorine salt deicing agents. Among them, sodium chloride is widely used due to its wide source, low price, large consumption. The impacts of chlorine salt deicing agents on the environment mainly include: corroding ...
