Embodiment 1
[0027] (1), 70 parts of sodium chloride and 20 parts of calcium chloride are stirred and mixed to obtain a chloride salt mixture; 35 parts of sodium silicate, 30 parts of sodium dihydrogen phosphate, 10 parts of sodium tartrate and 25 parts of thiourea are mixed to obtain Corrosion inhibitor; 60 parts of urea and 40 parts of sodium bicarbonate are mixed according to the proportion to obtain a pH regulator;
[0028] (2), 90 parts of chlorine salt mixtures, 5 parts of corrosion inhibitors and 5 parts of pH regulators prepared in step (1) were stirred and mixed to obtain the crude product of deicing agent;
[0029] (3) Stir, pulverize and granulate the homogeneously mixed snow-melting agent rough product, and pass through a standard sieve with an aperture of 6 mm to obtain granular environmental-friendly snow-melting agent;
[0030] (4) Place the solid PDMS in the lower layer of the closed heating furnace, and place the granular environmentally friendly snow-melting agent prepare...
