Problems solved by technology

The problem that comes with it is: the requirements for the air filter have increased
However, in the field of air filtration, there are no mature anti-photoaging products, and they are still in the research and development stage.
[0004] In short, there are currently no effective and practical photoaging-resistant polymer monofilaments for air filters, nor effective and practical precursor materials for the preparation of photoaging-resistant polymer monofilaments

Abstract

An anti-photoaging composition, filament containing it, its production and use are disclosed. The composition consists of hindered amine light stabilizer 10-22wt%, phenol antioxiant 8-14wt% and residual polymer from at least one of polypropylene, polyethylene, polystyrene, polyester and polyamide. The filament consists of anti-photoaging composition 2-10wt% and residual polymer from at least one of polypropylene, polyethylene, polystyrene, polyester and polyamide. It has good anti-photoaging performance and can be used for sand block and filter net.

Description

technical field [0001] The invention relates to a photoaging-resistant polymer composition, a photoaging-resistant polymer monofilament comprising the composition, a preparation method and application thereof. The composition of the invention has the properties of anti-light aging and anti-oxidation, and is a novel composite material. The anti-light aging monofilament of the present invention can be woven into an air filter net and applied in the air filter. Background technique [0002] With the improvement of social living standards, people have higher and higher requirements for the air quality output by air conditioners and air purifiers that are widely used. Therefore, ultraviolet sterilization technology has been applied to the field of air purification. The problem that follows is that the requirements for the air filter have increased. It must not only be able to filter out dust in the air, but also have the function of anti-photoaging, especially anti-ultraviolet ...
