Description
Technical field
The invention belongs to polymeric material field, more particularly, to a kind of thermoplastic elastomer alloy material and its preparation side
Method.
Background technology
Communication system is to be launched electromagnetic wave signal come transmission information day using radiation components such as the oscillators in antenna
The engineerings such as radio communication, broadcast/TV, radar, navigation, electronic countermeasure, remote sensing, radio astronomy, the WIFI touched in often
System belongs to communication system.Antenna plays central role in whole communication system, during antenna installation and use,
In order to protect radiation component not by external world or interference, generally also protective housing is provided with outside radiation component, is utilized
The housing is surrounded radiation component to play a protective role.In order to play the maximum effect of antenna, it is desirable to antenna casing pair
The transmission of electromagnetic wave affects as little as possible, therefore the material to shell selects the electricity function index value for needing to consider material, example
Such as, dielectric constant, tangent angle loss value etc., sheathing material relative dielectric constant is bigger, then electromagnetic wave is in air and antenna casing
Reflection on interface is bigger, and this will reduce electromagnetic transmission efficiency；Loss angle tangent tg δ is bigger, and electromagnetic wave is penetrating day
The energy for being converted into heat and being lost in line shell procedure is more.Further, since the use environment of some antennas is in open air,
Therefore higher requirement is proposed to the ageing properties of sheathing material.
At present communication antenna sheathing material is broadly divided into thermosets and thermoplastic, and thermosets is mainly used
Unsaturated polyester resin, epoxy resin, phenolic resin, vinylite etc. are composited with glass fibre, thermosets machine

The advantages of this is relatively low.Although PVC material has many advantages, such as, heat-resisting poor (60 DEG C or so of heat distortion temperature) is there is also,
Dielectric constant of a relatively high (3-4.8), intensity is relatively low, and true qualities contain the defects such as halogen.Additionally, antenna casing material is conventional
Thermoplastic also comprising the material such as ABS, ASA, HIPS, PP, ABS, PS material dielectric constant is 2.8-3.0, low price,
Due to containing unsaturated double-bond in molecular structure itself, therefore it is not suitable for using out of doors.ASA has excellent weather resistance, and is outdoor answering
Preferred material, but ASA dielectric constants are between 2.8-3.3 and relatively costly, which limits it makes on a large scale
With.PP material dielectric constants are 2.2 or so, and density is low, with low cost, but intensity is relatively low, aging is poor, also limit it
Use.
At present, the material of communication antenna shell is toward the side such as low-k, high durable, low weight, environmental protection, recyclable
To development, at present more or less all there is certain defect in existing thermosetting or thermoplastic.It is fast with the communications industry
Speed develops, either the spread speed and quality requirement more and more higher of State-level or ordinary consumer to signal, therefore, exploitation
Wave transparent performance is good, high durable, the antenna casing material of environmental protection have important economic worth and social effect.
