8. A synthetic method of a reflective coating of a high-speed guardrail is characterized by comprising the following steps:

sequentially putting raw materials of the reflective paint into a plurality of feeding hoppers (2) of a high-speed guardrail reflective paint synthesizing device according to any one of claims 1 to 7 in a mixing sequence, detecting the liquid level change in a conveying pipe (21) through an infrared sensor, and controlling a first valve (211) to be closed and monitoring a detection signal sent by the infrared sensor by a controller when the liquid level in the conveying pipe (21) exceeds a preset threshold value;

starting a conveying mechanism, enabling the batching barrels arranged on the conveying belt (43) to pass through the plurality of feeding hoppers in sequence and intermittently, and controlling a second valve (212) to be opened and a motor (44) in the conveying mechanism (4) to pause when an infrared sensor detects that the batching barrels reach a designated position;

in the process that the conveying mechanism (4) suspends the movement, the liquid output by the material conveying pipe (21) is contained by the batching barrel (3);

after the raw materials are collected in the batching barrel (3), the raw materials in the batching barrel (3) are sent into a high-temperature stirring chamber to be stirred, melted and mixed to obtain the coating, and the obtained coating is packaged by a plastic packaging bag.

9. The method for synthesizing the reflective coating of the high-speed guardrail according to claim 8, wherein the raw materials of the reflective coating comprise emulsion raw materials, luminescent powder raw materials and water raw materials;

10. The method for synthesizing the reflective paint of the high-speed guardrail according to claim 9, wherein the reflective paint further comprises alkanolamine, bentonite, dibutyl phthalate, industrial alcohol and pigment.
