Description
Technical Field
The invention belongs to the technical field of antenna covers, and particularly relates to a glass fiber reinforced plastic pultrusion antenna cover for a 5G base station and a preparation method thereof.
Background
The antenna housing is a structure for protecting the antenna system from being influenced by the external environment, and can protect the antenna system from being influenced by wind, rain, ice, snow, sand, dust, solar radiation and the like, so that the working performance of the antenna system is stable and reliable, and meanwhile, the abrasion, corrosion and aging of the antenna system are reduced. The service life of the antenna system is prolonged. Therefore, the radome is required to have excellent mechanical properties and good electrical properties such as wave transmittance and standing-wave ratio.
Glass Fiber Reinforced Plastic (FRP) is a scientific name of fiber reinforced plastics and can be classified into glass fiber reinforced composite plastics, carbon fiber reinforced composite plastics, boron fiber reinforced composite plastics and the like according to different fibers. The composite material uses glass fiber and products thereof as reinforcing materials and synthetic resin as matrix materials, and has the advantages of light weight, high strength, corrosion resistance, good thermal property, good designability, excellent manufacturability and the like.
At present, the glass fiber reinforced plastic radome is mainly formed by heating, curing, pultrusion and molding unsaturated polyester resin as a matrix and alkali-free glass fiber as a reinforcing material through a mold. The method is widely applied to the construction of base station facilities at home and abroad, and is a conventional accessory for the construction of base stations.
At present, the detection frequency point 1GHZ of the glass fiber reinforced plastic radome manufactured in China generally has the dielectric constant of 3.8U, the dielectric loss of 15-20mU and the density of about 1.8G/cm3, and can meet the construction requirement of a 4G base station. With the development of the communication industry, 5G base stations with faster transmission are built at home and abroad, the 5G base stations have higher requirements on indexes such as dielectric constant, dielectric loss, density and appearance of the glass fiber reinforced plastic radome, and the traditional glass fiber reinforced plastic pultrusion radome cannot meet the construction of the 5G base stations. Nowadays can satisfy 5G basic station's radome for plastics radome, but the manufacturing cost of plastics radome is higher, reaches 23 yuan/kg, and this will greatly increased 5G basic station's construction cost.
The application text with the application number of Z L201210128186. X discloses a glass fiber reinforced plastic radome, and the glass fiber reinforced plastic radome prepared by applying the glass fiber reinforced plastic radome can be used for enhancing the mechanical property of the radome and reducing the thickness of the radome on the premise of ensuring the electrical property, but the radome is only suitable for 4G base stations and base stations below and is not suitable for 5G base stations.
In summary, the technical problems that the glass fiber reinforced plastic radome is not suitable for a 5G base station in terms of performance indexes such as dielectric constant, dielectric loss and density and the like, and the cost of the plastic radome is too high exist in the prior art.
