Problems solved by technology

However, PVC is a polar material. Because its structure contains polar chlorine atoms, its total surface energy is high, especially the non-polar part of the surface energy is low, which eventually makes the surface of the material easy to be hydrophilic.
The PVC antenna cover is used outdoors for a long time, and a large amount of dust in the air is easy to adhere to the surface of the cover, which will affect the transmission signal

Abstract

The invention discloses a base station antenna polyvinyl chloride (PVC) profile housing with a surface self-cleaning function. The mechanical properties of the PVC profile housing are improved, the ultraviolet light resistance is greatly increased; and moreover, the non-polarity of the surface energy of the profile is significantly increased, thus the surface water contact angle of the profile is significantly increased, the hydrophobicity is increased and the surface self-cleaning function can be achieved. The base station antenna PVC profile housing with the surface self-cleaning function is prepared from the following raw materials in parts by weight: 100 parts of PVC, 1-3 parts of organotin stabilizer, 5-10 parts of polyacrylate toughening agent, 1-3 parts of polyacrylate processing aid, 5-10 parts of titanium dioxide, 0-5 parts of calcium carbonate, 3-5 parts of calcium stearate, 0.3-1 part of polyethylene wax, 0.2-1.2 parts of silicone oil, 0.3-1.2 parts of fluorosilicone oil and 0.2-1 part of organic fluoride.

Description

technical field [0001] The invention relates to a profiled material cover and a preparation method thereof, more specifically to a PVC profiled material cover for a base station antenna with surface self-cleaning function and a preparation method thereof. Background technique [0002] With the rapid development of the mobile communication industry, mobile phones provide convenience and speed for people's work and life more and more. The base station antenna is an important part of the mobile communication wireless access system. People have higher and higher requirements for call quality, and electronic components that transmit special radio frequency signals play a very important role. At the same time, the antenna cover of the base station also makes a great contribution to protecting the electronic components and making them work normally. Since the microwave communication antenna is placed outdoors for a long time, it is not only required that the outer cover has a low ...
