Light Stabilizer for Nylon

The present invention provides a light stabilizer composition for nylon, in which the components that mainly play a light stabilizing effect include a hindered amine light stabilizer containing an amide energy group and a polymeric hindered amine light stabilizer. The combined use of the hindered amine light stabilizer and the high molecular weight polymeric hindered amine light stabilizer can produce obvious synergy. The performance of the polymeric hindered amine light stabilizer to resist extraction and not easy to lose can make up for the amide energy. The hindered amine light stabilizer of the group is insufficient, and the combination of the two can significantly improve the processing performance and light aging performance of nylon materials
