NOVELTY - A lidar diffuse reflection calibration board includes base layer and diffuse reflection layer, where the diffuse reflection layer is formed by spraying diffuse reflection coating, and the diffuse reflection coating is prepared using 20-40 pts. wt. barium sulfate, 12-22 pts. wt. silicone resin grease, 3-8 pts. wt. methyl etherified high imino melamine resin, 6-12 pts. wt. composite sol, 5-10 pts. wt. titanium dioxide, 1-5 pts. wt. modified barium sulfate whiskers, 0.2-0.6 pt. wt. defoamer, 0.1-0.4 pts. wt. fluorine-containing silane coupling agent, and 15-25 pts. wt. solvent. USE - Lidar diffuse reflection calibration board. ADVANTAGE - Since the diffuse reflection layer is formed by spraying the diffuse reflection coating on the substrate after curing, the diffuse reflection layer has excellent water resistance and wear-resistant properties.
