Abstract

The invention discloses anti-light-aging polypropylene nonwoven fabric. After polypropylene and assistants are melted, mixed, extruded, air drawn, cooled, cured, lapped and reinforced, the polypropylene nonwoven fabric is prepared, and then low-temperature plasma treatment is conducted on the polypropylene nonwoven fabric; after the polypropylene and the assistants are melted, mixed, extruded, air drawn, cooled, cured, lapped and reinforced, the polypropylene nonwoven fabric is prepared, and then low-temperature plasma treatment is conducted on the polypropylene nonwoven fabric, and the prepared polypropylene nonwoven fabric not only has good mechanical properties, especially good tensile strength, but also has the good anti-light-aging property. Through the synergistic effect of nano diatomaceous earth after surface modification and nano-iron oxide, the tough portion of the polypropylene nonwoven fabric can be improved, the sticking points of fibers in the polypropylene nonwoven fabric is increased, the acting force between the fibers is increased, the overall mechanical properties of the polypropylene nonwoven fabric is improved, and the light aging is decelerated.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabrics, and in particular relates to a light-resistant aging polypropylene non-woven fabric. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. They are a new generation of environmentally friendly materials. Low cost, recyclable, etc. Polypropylene non-woven fabrics have the advantages of low cost, light weight, corrosion resistance and good chemical stability and are widely used. However, polypropylene non-woven fabrics are weak in light aging resistance. After that, it is easy to age and has a low lifespan.
