Embodiment 1
[0015] A light-resistant aging polypropylene non-woven fabric, comprising melting and mixing polypropylene and additives, extruding, air-stretching, cooling and solidification, laying and strengthening to make polypropylene non-woven fabric, and then polypropylene non-woven fabric low temperature plasma treatment;
[0016] The auxiliary agent is surface-modified nanometer diatomite and nanometer ferric oxide.
[0017] The preparation method of the nanometer iron ferric oxide is as follows: after mixing the ferric sulfate solution with a mass fraction of 2% and the ferrous sulfate solution with a mass fraction of 3.5% in a mass ratio of 2:1, add a precipitant at 50°C to make it Hydroxide colloids are formed and precipitated, and the colloids are dehydrated to obtain nano ferric oxide particles, which are then washed and dried.
[0018] The precipitating agent is ammonia water with a mass fraction of 20%.
