Abstract

The invention provides a high-temperature-resistant and rainfall-erosion-resistant wave transmission antenna housing and a preparation method thereof. The high-temperature-resistant and rainfall-erosion-resistant wave transmission antenna housing comprises an antenna housing body and a rainfall-erosion head, wherein the rainfall-erosion head is connected to the antenna housing body through a high-temperature-resistant wave transmission adhesive; the high-temperature-resistant wave transmission adhesive comprises epoxy-modified organic resin, mica powder, fumed silica, a silane coupling agent and an imidazole curing agent; the mica powder, the fumed silica, the silane coupling agent and the imidazole curing agent are sequentially added to the epoxy-modified organic resin. According to the high-temperature-resistant and rainfall-erosion-resistant wave transmission antenna housing, a special intermediate-temperature normal-pressure curing type high-temperature-resistant wave transmissionadhesive is adopted, so that the rainfall erosion head and the housing body can be adhered in high temperature environment; the temperature resistance and reliability of the rainfall erosion head andthe housing body in connection are ensured; and the influence of the mounted rainfall erosion head on the electric performance of a wideband antenna housing can be overcome.

Description

technical field [0001] The invention relates to a high-temperature-resistant and rain-erosion-resistant wave-transparent radome and a preparation method thereof, belonging to the technical field of radome. Background technique [0002] For supersonic aircraft, the appearance of the radome equipped with it is mostly a highly streamlined shape, and in the case of multiple flying and high-speed airflow erosion, rain erosion occurs on the head of the radome, which in turn affects the flying life of the radome . In order to solve the problem of rain erosion on the head of the radome and increase the number of flying times of the radome, the rain erosion head is generally installed on the head of the formed radome, but the temperature of the high-temperature resistant broadband wave-transparent radome is high (up to 500 ℃), frequency bandwidth (1.2GHz-10.6GHz), the temperature resistance and reliability of the connection between the rain erosion head and the cover body, and the i...
