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...
