Sustained-release and salt containing anticoagulation is a kind of admixture which can take the initiative to melt snow on the road. However, currently most of products on the market are foreign products, and few domestic products do not have a long-term effect. To enhance sustained-release and long-term effect of anticoagulation, this paper chooses different carriers, preparation methods, surfactants, the concentration ratio of saline content carriers to surfactant, surfactant modification

Studies determine that the modified volcanic powder is used as a carrier, that samples which possess well sustained release character, that using Span-80 and Span-60 as surfactants to have the package on carriers, that the proportion of surfactants and saline content carriers for 1:5 is the best, that surfactant modified temperature is 80°C. 45 This is an open access article under the CC BY-NC license ( Modification of Volcanic Rocks Volcanic rocks were ground and calcined at 800~900°C. Modification volcanic powder with specific surface areas≥ 350m2/kg was prepared. Preparation of Saline Content Carriers According to the ratio, separately added modification volcanic powder, volcanic powder, diatomaceous earth, zeolite and fly ash in saturated brine at 20~30°C, mixed 4~5h then dried to constant weight at 105~120°C. Saline content carriers were prepared. Preparation of Sustained-release of Surfactant Solution According to mass ratio of organic solvents and surfactants as (1~10): 1, mixed them up, heated to 60~70°C, stirred 25~30min. Sustained release of surfactant solution was prepared. Preparation of Anticoagulation According to the ratio, saline content carriers were added to sustained-release of surfactant solution, mixed 4~5h, dried to constant weight at 130~140°C. Anticoagulant ice agents were prepared.
