Glass fiber reinforced plastic pultrusion radome for 5G base stations and preparation method thereof

Abstract

The invention belongs to the technical field of radomes, and particularly relates to a glass fiber reinforced plastic pultrusion radome for 5G base stations and a preparation method thereof. The glassfiber reinforced plastic pultrusion radome for 5G base stations is formed by pultrusion of glass fibers, unsaturated polyester resin, a flame retardant, aluminum hydroxide, filler, PE powder, an ultraviolet light absorber UV-2, an antioxidant, a release agent, a high-temperature curing agent, a medium-temperature curing agent and a low-temperature curing agent. The density of the glass fiber reinforced plastic pultrusion radome product for 5G base stations is 1.1-1.3 g/cm<3>, the dielectric constant is 2.8+/-0.2 u, the dielectric loss is 5-10 mu, the material is suitable for construction requirements of 5G base stations, the same performance requirements of plastic radomes can be met, and the mechanical properties, corrosion resistance and high and low temperature resistance of the material are superior to those of the plastic radomes. In addition, the cost of the glass fiber reinforced plastic pultrusion radome for 5G base stations is lower, and the construction cost of a 5G base station is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of radome, and in particular relates to a fiberglass pultruded radome for a 5G base station and a preparation method thereof. Background technique [0002] The radome is a structure that protects the antenna system from the external environment. It can protect the antenna system from wind, rain, snow, sand and solar radiation, etc., so that the performance of the antenna system is relatively stable and reliable, while reducing the wear and tear of the antenna system. corrosion and aging. Extend the life of the antenna system. Therefore, the radome is required to have both excellent mechanical properties and good electrical properties, such as wave transmittance, standing wave ratio, etc. [0003] Fiberglass reinforced plastics (FRP) scientific name fiber reinforced plastics, according to the different fibers can be divided into glass fiber reinforced composite plastics, carbon fiber reinforced composite pl...

AI Technical Summary

Problems solved by technology

With the development of the communication industry, 5G base stations with faster transmission have been built at home and abroad. In 5G base stations, there are higher requirements for the dielectric constant, dielectric loss, density and appearance of FRP radome. Traditional FRP pultrusion Radome can no longer meet the needs of 5G base station construction

Nowadays, the radome that can satisfy 5G base stations is a plastic radome, but the manufacturing cost of plastic radome is relatively high, reaching 23 yuan / kg, which will greatly increase the construction cost of 5G base stations

[0006] The application text with the application number ZL201210128186.X discloses a FRP radome. The FRP radome manufactured by applying this patent can strengthen the mechanical properties of the radome and reduce the thickness of the radome while ensuring the electrical performance. The radome is only suitable for 4G and below base stations, not for 5G base stations

[0007] To sum up, in the prior art, there are technical problems such as that the performance indicators of FRP radome are not suitable for 5G base stations in terms of dielectric constant, dielectric loss, density, etc., and the cost of plastic radome is too high.
