Abstract

The invention provides a heating and infrared anti-reflection type structural member as well as a machining method thereof. The structural member comprises the following layers of: a base material layer; a functional layer which covers the surface of the base material layer, is used for heating the structural member and can transmit infrared light, comprises a light-transmitting layer and a heating element fixedly connected to the surface of the light-transmitting layer, wherein the heating element is connected with a power supply after being led out of the light-transmitting layer through an anode pin and a cathode pin; an infrared anti-reflection layer which covers the inner surface of the functional layer and is used for anti-reflection of the infrared light, wherein the infrared anti-reflection layer is an AR anti-reflection film; and a waterproof layer which is used for preventing water for the functional layer and covers the inner surface of the infrared anti-reflection layer. The base material layer and the waterproof layer have infrared light permeability. According to the radome, a conductive heating function, demisting, deicing and other functions can be achieved; and meanwhile, the radome can transmit specific infrared wavelength functionally, and ensures reliable operation of a radar.

Description

technical field [0001] The invention relates to a heating and infrared anti-reflection structural part, a processing method and an application thereof. Background technique [0002] With the rapid development of intelligent fields such as AI intelligence and autonomous driving, more requirements are placed on product functions and requirements. Take the laser radar products that need to be matched in this kind of smart field as an example. The laser radar cover is usually injection-molded, and the infrared transmittance of injection-molded plastics (such as PMMA and PC) is not high (about ≥85%). The requirements of actual application scenarios put forward the following functional requirements for plastic products: [0003] 1. The outer layer of the radome product must meet the reliability and mechanical strength of the ring test; [0004] 2. The radome needs to realize the function of conductive heating (requirements such as defogging and deicing); [0005] 3. The functio...
