Title:
ROAD SURFACE COATING MACHINE
Document Type and Number:
Japanese Patent JP2023033038
Kind Code:
A
Abstract:
To provide a road surface coating machine capable of suitably applying a two-pack type polyurea coating for coating by adjusting the coating temperature.SOLUTION: A road surface coating machine comprises: a heating unit for respectively heating a main agent and a curing agent that constitute a polyurea coating; a liquid pressurizing unit for respectively applying pressure to the main agent and the curing agent; a mixing unit for mixing the main agent and the curing agent pressurized by the liquid pressurizing unit; and an injection unit having an injection port for injecting toward a road surface the polyurea coating mixed in the mixing unit. The mixing unit is arranged near the injection port and provided inside the injection unit. Since the mixing unit is arranged in the vicinity of the injection port and provided inside the injection unit, the mixing unit is less likely to be affected by air temperature. Thus, a decrease in the temperature of the main agent and the curing agent introduced into the mixing unit can be suppressed.SELECTED DRAWING: Figure 1
