| description | The invention relates to the technical field of polyamide preparation, in particular to a synergistic compound amidated light stabilizer for a polyamide material. The light stabilizer prepared by compounding an ultraviolet light absorber and a free radical trapping agent contains amidated groups highly compatible with the polyamide material; therefore, both the ultraviolet light absorber and the free radical trapping agent can form strong polar combination with polyamide molecules through amidation crosslinking, the breakage probability of polyamide is reduced, the thermal stability of the polyamide material can be effectively improved, and the light stabilizer can absorb ultraviolet light or contains light stabilizing groups, so that the light stabilizing effect is good. The anti-aging performance and the light stability of the polyamide material in the application process can be enhanced; in addition, the ultraviolet quencher in the stability enhancer can eliminate excitation energy generated by photo-therm |
