Attenuation performance of ultrasonic radar of automotive ASA materials
During the rainy season,rain will affect the direction of the radar wave emitted by the radar detector embedded in the acrylonitrile-styrene-acrylic acid copolymer(ASA)grid,resulting in misreport.The purpose of this work is to ex-plore the influence factors of automobile ASA grille material to improve the attenuation performance of radar wave and to reduce the risk of misreport by radar from the perspective of material optimization.The results indicated that the content and type of acrylate segment in the ASA material were the key factor,and the ASA powders with a high acrylate content and a small rubber particle size exhibited better attenuation performance of radar wave.
