Description
Technical Field
The invention relates to the technical field of communication materials, in particular to an antenna housing, and especially relates to a 5G antenna housing.
Background
5G is an abbreviation for fifth generation mobile communication system. The 5G plays a role of a booster in the development of the Internet of things and the industrial Internet. It is predicted that the future 5G application capability is 20% for consumers, 80% for industrial services, and the influence of 5G on the industrial field is far greater than that of the public consumption field, and 5G is a precursor of the 4.0 era of catering to industry, and the 4.0 era of industry is not free from the support of 5G technology. The 5G propagation needs a large number of base stations to be completed, and the base station construction is free from the role of an antenna. Since 5G antennas follow MIMO (Multiple-Input Multiple)
Output) concept means multiple input multiple Output, which means that multiple antennas can be installed in one base station, and the size of these antennas is small, which requires protection of the antenna housing.
The radome is a functional composite structural member, and the radome material is required to meet the requirements of dielectric property, mechanical property, three-protection service life, technological property, weight and the like. The dielectric properties of the material are mainly dielectric constant epsilon and loss tangent tg delta. The index directly affects the electrical performance of the radome and is the main basis for selecting materials. The greater the loss tangent tg delta, the more energy is lost by the electromagnetic wave energy being converted to heat during penetration of the radome. The greater the dielectric constant epsilon, the greater the reflection of the electromagnetic wave at the air-radome wall interface, which increases the mirror lobe level and reduces transmission efficiency.
However, in the process of realizing the technical scheme in the prior art, the applicant finds that the technical scheme in the prior art has the following technical problems:

The description of these embodiments is provided to assist understanding of the present invention, but is not intended to limit the present invention. In addition, the technical features of the embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
The 5G antenna housing material is used to protect the antenna system from external environments (such as snow, sunlight, living things, etc.), to extend the life of the antenna, and to ensure the permeability of electromagnetic waves. In the prior art, the antenna housing material cannot meet the requirements of dielectric property, mechanical strength, weather resistance and the like.
According to the technical scheme, the problem of insufficient electrical property, mechanical strength and weather resistance in the prior art is solved by providing the 5G radome, and the beneficial effects of improving the dielectric property, the mechanical strength and the weather resistance are achieved by adopting the modified PC resin and the modified ASA resin to combine basalt fibers with low dielectric glass fibers and fillers with hollow structures.

Wherein, the ASA replaces butadiene with butyl acrylate, and residual double bonds are not existed, so that the weather resistance of the ASA resin is more than 10 times of that of the ABS resin.
The rubber phase of the ASA resin is prepared by substituting polybutadiene in the ABS resin with acrylic ester, and the polymer chain does not have an unsaturated structure, so that the ASA resin has better weather resistance on the basis of having the performance similar to that of the ABS resin, and the defects of reduced mechanical strength, yellowing of the ABS resin caused by decomposition under sunlight irradiation and the like caused by long-term outdoor placement of the ABS resin are overcome. ASA resins have good impact resistance, colorability, chemical resistance.

Specifically, ECR glass fiber is selected as the low dielectric glass fiber.
More specifically, ECR glass fibers without boron and fluorine are selected.
The preparation method of the 5G radome of the embodiment of the present invention is the same as that of embodiment 1.
Compared with E-grade glass fiber, the corrosion resistance of the 5G radome prepared from the composite material can be obviously improved by adopting ECR glass fiber.
The corrosion mechanism of the E-grade glass fiber (hereinafter referred to as E-glass fiber) is as follows:
the process of the E-glass fiber eroded in water or in an acidic environment is the hydrolysis process of the metal example in the glass fiber
First, the metal ions on the surface of the E-glass fiber are hydrolyzed and diffused into the solution, and the ions in the glass fiber migrate to the surface of the glass fiber. At this point, the hydrolysis process continues and the metal ions migrating to the surface of the E-glass fiber continue to diffuse into the solution during the continuous hydrolysis process until equilibrium is reached.
Since the corrosion resistance of E-glass fibers is mainly related to the mobility of alkali metal ions, the mobility of alkali metal ions depends on the internal structure of the glass fibers. The more complete and dense the internal structure of the glass fiber, the greater the difficulty in ion migration. The degree of corrosion resistance depends on the difficulty of ion migration.
It can be seen that the strength of the corrosion resistance is related to the structure of the glass fiber, which is in turn related to the composition of the glass fiber.
If [ SiO4], [ AlO6], [ BO4] and [ BO3] exist in the glass fiber at the same time, the more complete the compactness degree of the internal network structure of the glass fiber is reduced, and the less complete the internal network structure of the glass fiber is reduced, the passing path of ion migration is increased.
Specifically, [ BO3] is a two-dimensional layered structure, and the interlayer force is weak, so that a channel for ion migration is easily formed. In addition, [ BO3] is easy to generate split phase, weakens the integrity degree of the stripping force network structure in the glass fiber, and forms more ion migration channels.
In order to improve the corrosion resistance of the glass fiber, the glass fiber with high electric field and high coordination ions, such as the glass fiber capable of generating Ti4+ and Zn2+, can effectively limit cations, thereby reducing the migration capacity of the cations.
The ECR-glass fiber has a certain content of TiO2 and ZnO, and can improve the corrosion resistance of the glass fiber.
The glass fiber which does not contain boron and fluorine can avoid the reduction of the integrity degree of the internal network structure of the glass fiber, thereby improving the corrosion resistance.
ECR comprises the following components:
50-60 parts of SiO2, 3 5-10 parts of Al2O, 15-20 parts of CaO, 1-3 parts of MgO, 2 2-5 parts of TiO, 1-3 parts of ZnO and 1-3 parts of BaO.

Comparative example 3

The electric glass fiber contains boron and fluorine.
The preparation method of the 5G radome of the present comparative example is the same as that of example 1.
The components of the embodiment and the comparative example show that the 5G radome prepared by adopting ECR-glass fiber has better corrosion resistance, particularly more remarkable high-temperature corrosion resistance, than the 5G radome prepared by adopting E-grade glass fiber.
To further improve the material properties of the radome, other additives may be added:
the cold-resistant agent or/and EPDM cold-resistant particles are added, so that the strength of the radome at low temperature can be further improved;
the ion trapping agent is added, so that the corrosion resistance of the high radome at low temperature can be further improved.
The 5G network is mainly based on the birth of high-frequency electronic equipment, and the high-frequency electronic equipment can generate larger heat energy, so that stronger electronic interference and stronger radiation to the equipment are generated, and the transmission efficiency and the service life of the equipment are reduced. Therefore, as power consumption increases, heat conduction problems of the electronic device also occur.
Furthermore, the combination of graphene can improve the comprehensive performance of the radome, and the mode of combining graphene comprises the adoption of a graphene coating or a graphene composite coating, so that the heat conduction capacity of the radome is improved.
The graphene has the characteristic of complex conductivity dynamic adjustability, and the directional radiation direction of the beam can be obtained by the dipole antenna arranged in the antenna housing through the antenna housing based on the graphene and controlling chemical potentials of different columns in the antenna housing.
More specifically, a graphene frequency selective surface or a graphene absorption surface is selected in the radome surface material, and the conductivity of graphene is adjusted by doping, externally applying an electric field or magnetic field bias, so that the flexibility of the radome structure is improved.
Furthermore, 1% -5% of graphene can be added into the raw materials, so that the advantages of high thermal conductivity of the graphene and other materials are brought into play together.
The 5G radome is exposed outdoors for a long time and is subjected to wind and rain, and if the surface of the radome is polluted by pollutants, the radome is not exposed to the sight of people in high places although the surface of the radome is not attractive. However, the pollutants often not only pollute the radome, but also can corrode the radome along with the accumulation of the pollutants if no protective measures are taken to prevent the radome from being damaged, and the radome is more and more seriously damaged originally when the weather changes, so that the protection of the antenna is finally affected.
And the anti-pollution protective coating is coated on the surface of the radome, so that the protection of the 5G radome is facilitated.
The anti-fouling protective coating can be selected from a slow-release photocatalytic anti-fouling self-cleaning coating and an abrasion-resistant super-hydrophobic coating.
Specifically, the slow-release photocatalytic antifouling self-cleaning coating is prepared by mixing high polymer resin and a photocatalyst in a stirring manner, and then ball-milling the mixture with a porous material, so that the high polymer resin composite photocatalyst is embedded with a nano-scale of percent on the porous material, and is combined with an inorganic binder. Wherein the photocatalyst is nano TiO2 and/or g-C3N4. The inorganic binder comprises 30% nanoparticle composition. The nano particles are selected from one of nano SiO2, nano ZrO2 or nano CaCO 3.
The titanium dioxide TiO2 can generate electron-hole pairs under ultraviolet irradiation, and hydroxyl radicals generated after oxidation-reduction reaction have high activity, so that organic pollutants can be decomposed, and self-cleaning is realized; meanwhile, after certain illumination, tiO2 can be converted into a super-amphiphilic surface, which is favorable for flushing pollutants in rainwater.
The organic semiconductor C3N4 is a polymer semiconductor, has a band system of about 2.7eV, can absorb visible light, contains only two elements of C and N, and has high hardness, wear resistance and chemical and thermodynamic stability.
The wear-resistant super-hydrophobic coating comprises a nano material dispersion liquid and a bonding material dispersion liquid, wherein the nano material dispersion liquid is a mixed solution of 1-5 mass% of nano materials and volatile solvents, and the bonding material dispersion liquid is a mixed solution of 10-40 mass% of bonding materials and good solvents of the bonding materials; the nano material is hydrophobic gas phase nano silicon dioxide or hydrophobic nano silicon dioxide aerosol powder, the particle size is 10-80nm, and the cluster size formed by the particles is 300-1500 nm; the binding material is polyurethane colloidal particles, polystyrene colloidal particles, fluorocarbon resin, organic silicon resin, phenolic resin, epoxy resin or alkyd resin, and the binding material dispersion liquid further comprises one or more of polypropylene, polyethylene, polyvinylidene fluoride, silicon dioxide and aluminum oxide with the size of 60-80 mu m accounting for 2-5 mass percent of the dispersion system. The water static contact angle of the surface of the coating is more than 160 degrees, the rolling angle is less than or equal to 5 degrees, and the hydrophobicity is excellent.
In order to further improve the durability of the coating, the nano material is partially embedded into the bonding layer, and the bonding force between the super-hydrophobic structure and the substrate is enhanced on the premise of ensuring the transparency, so that the durability of the coating is improved.
To further enhance the durability of the anti-fouling protective coating, oyster shell milled powders may be added. The outer wall made of the oyster shell can stand still for more than half a century, and the durability of the high-anti-pollution protective coating can be improved by combining the advantages of the outer wall into the coating.
The effect of the radome due to the attached pollutants can be avoided by coating or impregnating the 5G radome with the anti-pollution protective coating, in particular, using the anti-pollution protective coating with a self-cleaning function. The anti-fouling protective coating with the self-cleaning function can remove the influence caused by the attached pollutants by decomposing the attached pollutants. However, when the components that can produce the self-cleaning function are naturally exhausted or damaged due to the outdoor wind influence, the dirt resistance of the radome is inevitably compromised. Further solves the problem of dirt resistance and dirt resistance of the radome, and the more suitable method is to prevent the pollutant from adhering to the surface of the radome, and select the adsorption-preventing coating as the dirt-resisting protective coating.
The adsorption-preventing coating is coated or impregnated on the surface of the 5G radome, and when the contaminant contacts the surface of the radome, the contaminant cannot adhere to the surface of the 5G radome due to the adsorption-preventing coating.
Fully utilizes or refers to the anti-adhesion phenomenon in the nature, adopts bionic anti-adhesion interface materials, and realizes anti-adhesion to cells, bacteria, greasy dirt and minerals. For example:
1) Inspired by immune cell structure, various interface materials for cell capture and culture are prepared, and release of single cells or cell aggregates is realized by regulating wettability of the material surface;
2) Inspired by the superhydrophobic self-cleaning characteristic of lotus leaves, the superhydrophobic archwire is prepared, and the characteristics of antibiosis and nickel ion exudation resistance are realized;
3) Inspired by the characteristic that tannic acid in plants is easy to adhere, a coating with super-oleophobic and low-adhesion on the surface is prepared, and the characteristic of oil adhesion resistance is realized;
4) Inspired by the anti-calculus effect on the surface of the renal epithelial cells, the coating structure with the super-hydrophilic nano cilia gel on the surface is prepared, and the high-efficiency anti-adhesion property on minerals is realized.
The anti-adhesion property in the nature and the outdoor application scene of the 5G radome are combined, and the hydrophobic or oleophobic or amphiphobic material is used as the anti-adsorption coating to coat or impregnate the surface of the 5G radome, so that pollutants (including water-based or oily pollutants) cannot be adhered to the surface of the 5G radome.
The adhesion of the solid particles is caused by the mutual attraction of the residual force field of the solid surface and solid particles closely contacted with the residual force field of the solid surface, and the superhydrophobic surface for preventing dust accumulation is applied to the surface of the 5G radome. The silica sol-gel coating is coated or deposited on the surface of the radome as an anti-adsorption coating or an anti-adsorption deposition layer, so that the low surface energy functionalized mirror surface of the radome shows anti-adhesion behavior. Surface roughness less than 100nm provides the ability to repel solid particles, reducing dust adhesion. And spraying the modified silicon dioxide on the surface of the radome, and then cleaning and curing by using a solvent to obtain the antifouling super-hydrophobic radome surface. 2.6g of sand can be smoothly dropped from the surface of the radome and has excellent wear resistance. Similarly, when solid snowflakes fall on the surface of the antenna housing, the snowflakes can smoothly fall off from the surface of the antenna housing, and the effect of snow prevention is achieved. Specifically, the cavitation state surface of the silica sol-gel coating can reduce the adhesion area of the snowflake, so that the contact area of the snowflake is reduced, and finally the snowflake falls off from the surface of the radome under the action of gravity of the snowflake. Meanwhile, the antibacterial particles are combined with the surface of the super-hydrophobic radome, so that the surface of the anti-bacterial adhesion super-hydrophobic radome can be obtained.
In addition to the contamination of the radome by solid contaminants, liquid contaminants can also contaminate the radome. The performance of the radome may be compromised, such as by affecting the wave permeability, after contamination. The pollutants are mixed into the rainwater and sprinkled on the radome. The anti-adsorption coating prepared by the super-hydrophobic solution is preferably prepared by adopting a super-hydrophobic solution obtained by reacting vinyl triethoxysilane with TiO2 under alkaline conditions. The anti-adsorption coating prepared by the super-hydrophobic solution enables the surface of the radome to be randomly distributed with the nano particles wrapped by the oligomer, so that the surface of the radome has super-hydrophobic performance. The contact rate of the water drops containing pollutants and the anti-adsorption coating is 0.85-0.9, the water sliding angle is lower than 5 ℃, the water drops containing the pollutants can roll down from the surface of the radome very easily, the anti-liquid adhesion performance is good, the technical effect that the liquid pollutants are not easy to adhere to the surface of the radome is realized, the pollution resistance of the radome is improved, and the performance of the radome is reduced because the pollution is influenced.
When the radome is installed or overhauled, a small amount of high-viscosity liquid pollutants such as oil stains are inevitably adhered to the surface of the radome. The inside of the high-viscosity liquid drops such as oil stains is converted and lost between viscous energy and kinetic energy, so that the expansion and retraction speeds are slow. Hydrophobic and oleophobic amphiphobic coatings are used as anti-adsorption coatings, so that pollution of greasy dirt is reduced. The suspension prepared from natural nano clay or synthetic nano clay and fluorinated polysiloxane is coated on the radome, so that the super-hydrophobic and oleophobic coating is formed on the surface of the radome, wherein the nano rod-shaped microstructure of the nano clay promotes the coating to have excellent super-amphiphobic characteristics.
Exposure of the radome to the open air is subject to various stresses in addition to various contaminants in the air, which may have an effect on the radome structure as the high winds continue to blow onto the radome. It is therefore desirable to employ wave reinforcement structures on the outer surface of the radome, preferably provided at least one corner of the radome, the corrugations in the wave reinforcement structures extending from the vertical direction of the radome. The corner of the radome is generally a stress concentration part, and the stressed surface area of the radome is increased through the wave reinforcing structure, so that the pressure intensity generated by the stress is reduced, and the wave reinforcing structure also provides a cohesive force which is favorable for the structural firmness of the radome on the basis of decomposing the pressure intensity when the airflow passes through the surface of the radome, and finally the service life of the radome is prolonged.
The embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, and yet fall within the scope of the invention.
