Material and manufacturing method of lightweight 5G base station communication antenna housing

Abstract

The invention relates to the technical field of communication antenna housings, in particular to a material and a manufacturing method of a lightweight 5G base station communication antenna housing. The material comprises the following raw materials in parts by mass: 40-60 parts of PVC, 40-60 parts of ABS, 2.5-3.5 parts of an environment-friendly stabilizer, 1.5-3 parts of an impact modifier, 1.5-5 parts of a lubricant and an auxiliary agent, a plurality of parts of filler and a plurality of parts of foaming master batch. The method includes the following steps: step 1, a raw material ABS is dried; 2, the raw materials are put into a mixer to be evenly mixed; 3, the mixed raw materials are put into an extruder to be extruded into sheets; and 4, the sheet is put into a plastic suction machine to be subjected to plastic suction forming. Based on good dielectric properties, mechanical properties and weather resistance of an existing PVC and ABS composite modified material, a foaming mode of generating a closed-cell structure is adopted, so that performance parameters such as the dielectric constant and the dielectric loss angle tangent of the material are further reduced; meanwhile, the density of a finished product is reduced (on the premise of ensuring the properties such as mechanical properties and weather resistance), and light weight is realized from the material level.

Description

technical field [0001] The invention relates to the technical field of a communication antenna cover, and more specifically relates to a material and a manufacturing method of a lightweight 5G base station communication antenna cover. [0002] technical background [0003] The base station antenna is an important part of the mobile communication wireless access system. The base station antenna is used to convert the radio frequency power fed back by the transmitter into electromagnetic wave energy, or convert the electromagnetic wave energy into radio frequency power and transmit it to the receiver. The requirements are getting higher and higher, and electronic components that transmit special radio frequency signals play a very important role. With the evolution of mobile communication networks to 4G / 5G, high-quality, lightweight and integrated base station antennas are very necessary. The base station antenna products have different designs, but the main structure of the b...

Problems solved by technology

[0005] Now most of the market is 5G radome made of the following materials: Take the radome made of polyimide composite material as an example. The cost is very high and cannot be used in a large area

Epoxy resin prepreg has excellent physical properties. When used as a 5G radome, its thickness can be reduced, and the dielectric loss tangent of the material will also be lower, but the dielectric constant does not decrease, and the weight is too large to be inconvenient for high-altitude installation.

The 5G radome made of thermoplastic engineering plastics and glass fiber, including continuous glass fiber reinforced polypropylene composite material (CGF-PP), has lower signal loss than conventional materials and excellent wave transmission performance, which can meet the high-frequency requirements of 5G communication materials. Low loss requirements, but heavy weight, inconvenient for high-altitude installation work

[0006] PVC and ABS materials are widely used in all walks of life because of their low cost, easy processing, and wide source of materials, especially in the extrusion molding industry, especially in recent years with the development of PVC and ABS composite modification technology , which greatly expands the application field of this material. The general compound modification of PVC and ABS can improve its dielectric properties, mechanical properties, good weather resistance, mechanical strength and processing performance, but the commonly used PVC and ABS compound modification materials Although it can meet the requirements of low dielectric constant, low dielectric loss tangent and weather resistance required by 5G base station radomes, it is dense, heavy, and inconvenient to install and transport. Therefore, it is urgent to develop an optimized and improved PVC composite modified material. While meeting various mechanical performances, it can also meet the requirements of low dielectric constant, low dielectric loss tangent, environmental protection and low cost.
