Low dielectric constant FRP radome and its production process

Abstract

The invention relates to the field of radome, in particular to a low-dielectric-constant glass fiber reinforced plastic radome and its production process, comprising a mounting base for installation on a wall, an openable and closable protective cover arranged outside the mounting base, a The antenna holding rod in the cavity formed by the seat and the protective cover, the glass fiber reinforced plastic base is calculated by mass parts, including 50-80 parts of unsaturated polyester resin, 5-20 parts of glass fiber, 2-15 parts of carbon nanotubes, 1 , 0.5-4 parts of 3-butanediol, 5-30 parts of heat-resistant modifier, 5-10 parts of low shrinkage agent, 1-5 parts of release agent, 5-15 parts of coupling agent, 1 part of fluorinated graphene ‑5 parts, initiator 1‑5 parts, thickener 1‑5 parts. The glass fiber reinforced plastic of the invention has the advantages of small dielectric constant, good wave permeability, high mechanical strength and long service life.

Description

technical field [0001] The invention relates to the field of radome, in particular to a low dielectric constant fiberglass radome and a production process thereof. Background technique [0002] With the development of modern mobile communication technology, the current mobile communication technology is entering the 5G era. 5G is not a single wireless access technology, nor is it several new wireless access technologies, but a general term for solutions that integrate a variety of new wireless access technologies and existing wireless access technologies. A truly converged network. [0003] As the next-generation mobile communication network, 5G network is also an extension after 4G. It is faster than the current 4G network transmission speed, at least ten times or even hundreds of times the current 4G transmission speed. Tens of Gb per second. The Ministry of Industry and Information Technology of my country is also conducting 5G technology research and development trial...

AI Technical Summary

Problems solved by technology

[0004] The large-scale application of 5G networks requires the construction of a large number of antennas. Outdoor antennas are usually placed in the open air and are directly attacked by storms, ice, snow, dust, and solar radiation in nature, resulting in reduced antenna accuracy, shortened life, and poor operating reliability.

However, the existing antenna cover does not meet the requirements of stable physical, mechanical, electrical and chemical properties in terms of mechanical properties, the effect of glass penetration cannot achieve the desired effect, and the dielectric constant cannot be reduced while achieving strength
