Embodiment Construction
[0014] This specific embodiment adopts following technical scheme: its raw material ratio is (kg / m ³):
[0015] (1): phase change wax: 40-55;
[0016] (2): High-density polyethylene: 15-25;
[0017] (3): Polyacrylamide: 10-15;
[0018] (4): stearic acid: 10-15;
[0019] (5): Sodium hydroxide: 5-7.
[0020] A method for manufacturing ice and snow melting phase change materials for road asphalt mixtures. The manufacturing method is as follows: put phase change wax into a mixer according to the proportion, and heat it to 190°C; then add high-density polyethylene and polypropylene according to the proportion Amide and stearic acid are mixed and stirred evenly, and then enter the molding machine. After molding, they are washed with sodium hydroxide and then air-dried; packaged, measured, and registered for storage.
[0021] The working principle of this specific embodiment is: it is mainly used in fields such as highways, airports, urban roads, and sports venues. It uses a com...
