Embodiment 1
[0035] Take the preparation of 100g of low-corrosion composite chlorine salt deicing agent as an example, which contains the following raw materials in proportions by mass:
[0036]
[0037] The number average molecular weight of the said polyethylene glycol is 2000-10000.
[0038] The preparation method of above-mentioned deicing agent is made up of the following steps:
[0039] (1) Mix calcium chloride dihydrate and magnesium chloride hexahydrate according to the above mass ratio, mechanically pulverize, and pass through a 50-mesh sieve to obtain a mixture of calcium and magnesium chloride salts.
[0040] (2) Mix other raw materials according to the above-mentioned ratio of parts by mass, stir evenly, and pass through a 100-mesh sieve to obtain an additive mixture.
[0041] (3) Put the mixture of calcium and magnesium chloride salts in step (1) and the additive mixture in step (2) into a mixer and stir evenly, dry at high temperature, granulate into a particle size of 5 ...
