How can the aging problem of sunshade nets be solved?

The sunshade net, also known as the shading net, is a latest type of special protective covering material that has been promoted in the past more than ten years and is used for agriculture, fishery, animal husbandry, wind protection, soil covering, etc. After being covered in summer, it plays the roles of blocking light, blocking rain, retaining moisture and reducing temperature. 

However, due to the intense exposure to the sun in summer, the sunshade net is prone to aging, becoming brittle and breaking. How to solve this problem? This problem can be solved as long as the anti-aging masterbatch for sunshade nets is added to the sunshade net.
