Problems solved by technology

Usually, the reversing radar only detects the objects directly in front of the detector, but in the rainy season, rainwater will flow into the gap between the detector and the car parts, causing a small part of the radar wave signal to be emitted to the sides of the detector.
When this small part of the radar signal is transmitted in the car parts, when it encounters metal or electronic parts, it will reflect a small reflection signal back to the radar receiver, causing the radar wave receiver to receive the signal prematurely and generate false alarms. confuse the driver while driving

Abstract

The invention discloses an acrylonitrile-styrene copolymer material for promoting ultrasonic attenuation and a preparation method thereof, belonging to the technical field of polymer materials. The acrylonitrile-styrene copolymer material for promoting ultrasonic attenuation according to the present invention comprises the following components in parts by weight: 40-90 parts of acrylonitrile-styrene resin and 10-50 parts of ultrasonic attenuation agent; the ultrasonic attenuation agent comprises acrylonitrile -Styrene-Acrylate Copolymer, Acrylonitrile-Styrene-Butadiene Copolymer, Acrylonitrile-Styrene-Ethylene-propylene Rubber Copolymer, Acrylate-Styrene-Butadiene Copolymer, Styrene-Ethylene- At least one of butene-styrene copolymers. The acrylonitrile-styrene copolymer material prepared by the formula of the present invention can make the radar wave signal of false alarm to be lost in the transmission process, and can be used to prepare the grille, bumper and car logo of the vehicle equipped with the ultrasonic radar wave detector and other auto parts.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an acrylonitrile-styrene copolymer material and a preparation method thereof. Background technique [0002] "Intelligence" is one of the important themes in the development of the automobile industry. With the development of automotive electronic technology, automotive intelligent technology has been gradually applied, the operation of the car is getting simpler and safer, and the driving safety is getting higher and higher. For example, parking assist systems, automatic parking systems, and even autonomous driving systems have entered human life and play an important role in driving cars today and into the future. [0003] In the process of car parking, ultrasonic radar is the most common and mature radar detection system. Compared with other radar waves, it has the characteristics of better detection accuracy and faster and more timely data transmission c...
