Problems solved by technology

[0004] Nevertheless, the mainstream PVC antenna cover on the market will undergo large deformation after high and low temperature impact, and because the linear expansion coefficient difference between the antenna cover and the reflector is large, it will cause the end cover of the antenna cover to separate from the antenna cover. Problems such as poor waterproofing
Moreover, the existing PVC antenna cover can only be used in scenarios where the temperature is between -40°C and 70°C, which cannot meet all-weather application requirements
The manufacturing cost of the existing PVC antenna cover is also relatively high. In order to improve the heat resistance of the antenna cover, a large amount of heat-resistant modified resin ABS has been added, resulting in high manufacturing costs, and the addition of ABS will also lead to a decrease in the UV resistance of the antenna cover. reduce
Furthermore, the prior art does not address the thermo-oxidative aging effects affecting PVC antenna covers

Abstract

The invention discloses a preparation method of an ultraviolet resistant and aging resistant antenna outer cover. The preparation method comprises the following steps of (1) mold manufacturing; (2) blister forming; and (3) adhesion. The preparation method adopts a method of separately processing and then adhering to form the whole antenna outer cover, on the one hand, the processing difficulty isreduced, and on the other hand, the processed antenna outer cover has large strength and anti-ultraviolet and anti-aging functions.

Description

technical field [0001] The invention relates to a preparation method of an anti-ultraviolet and anti-aging antenna cover, which belongs to the technical field of plastic absorption. Background technique [0002] Communication base station antennas are generally installed at high altitudes, such as iron towers or roofs. after installation [0003] Base station antennas are exposed to harsh outdoor environments for a long time. Therefore, antenna cover materials need to have characteristics or performances such as high and low temperature impact resistance and UV (ultraviolet, ultraviolet) radiation resistance, so as to meet their long-term and reliable outdoor applications. PVC (polyvinyl chloride, polyvinyl chloride) material has the characteristics of low dielectric, corrosion resistance, cold resistance, UV resistance and self-flammability. Compared with the traditional antenna cover material FRP, it also has light specific gravity, low cost and good formability. , recyc...
