[0021] The preparation method of compound liquid is:
[0022] A. According to the number of parts by mass, take 60~70 parts of water, 30~35 parts of pond sludge, 16~19 parts of soybean meal, 10~16 parts of rice bran, 4~6 parts of peptone, 1~3 parts of agar, stir well, put put into a fermenter, ferment at 30-40°C for 1-3 days, and collect the fermentation mixture;
[0023] B. Filter the fermentation mixture, collect the filtrate, adjust the pH to neutral, and concentrate under reduced pressure to 60-70% of the volume of the filtrate, and collect the concentrate to obtain the compound solution.
[0024] The additive is any one of L-ascorbyl palmitate and tea polyphenols.

The invention discloses a preparation method for an environmentally-friendly snow-melting agent, and belongs to the field of pavement materials. The preparation method comprises the following steps that mesoporous silica, water and N-methyl pyrrolidone are taken and put into a container and are stirred and mixed, the pH value is adjusted, ultrasonic vibration is carried out, and then a surfactantand oxalic acid are added for heating; after heating is completed, freeze-drying is carried out, a dried product, 3-aminopropyltriethoxysilane and xylene are taken, heating and refluxing are carried out, filtering is carried out, washing is carried out by using diethyl ether, and drying is carried out so as to obtain modified mesoporous silica; composite liquid, the modified silica, a PBS buffer solution and an additive are added into the container, and stirring and standing are carried out; and after standing is completed, calcium hydroxide and ferrous sulfate are added, mixing is carried out, standing is carried out overnight, filtering is carried out, filter residues are collected, air-drying is carried out, and an air-dried object, ethylene glycol and calcium oxide are uniformly mixedso as to obtain the environmentally-friendly snow-melting agent. The preparation method has the advantages that the problems that a pavement is corroded, and residues of an existing snow-melting agentare prone to cause soil pollution due to the fact that the current snow-melting agent is prone to remain a large amount of chlorine ions on the pavement after snow melting can be solved.
Description
technical field [0001] The invention belongs to the field of pavement materials, and in particular relates to a preparation method of an environment-friendly deicing agent. Background technique [0002] The snow and ice on the road surface in winter greatly reduces the adhesion coefficient of the road surface, which seriously affects the smooth flow of the road and driving safety. Traditional snow removal methods such as manual, mechanical, and deicing agents cannot maintain road safety anytime, anywhere for a long time. Along with the continuous expansion of city scale, the impact of winter snow on urban road traffic and urban life has become more and more prominent, and the use of deicing agent has become one of effective methods for removing road snow. [0003] As the name suggests, the deicing agent is used to melt snow and ice. Instead of salt, it is mainly used for deicing and deicing of urban roads, expressways, airports, ports, bridges and other facilities. Agents ...
