Abstract: The effect of UV aging on the properties of flame retardant modified epoxy resin (E51) after adding different ratios of light stabilizer Tinuvin 770 and antioxidant Irganox 1010 was studied. Chemical structure, surface morphology, mechanical properties, flame retardant properties and thermal properties were tested, it is found that UV irradiation destroys the structure of flame retardants, and degrades and oxidizes epoxy re-sins. Different ratios of anti-aging agents improve the retention rates of mechanical properties and flame retardant properties. Antioxidant-only samples showed the best performance after 28 d of aging. The retention rates of tensile and flexural strengths increased to 100.10% and 92.50%, compared with 80.37% and 81.61% of the samples without anti-aging agent. The limiting oxygen index (LOI) increased from 34.4% to 37.5% and the antioxidants made the thermal stability of the samples better. The results show that the addition of antioxidant Irganox 1010 is the best for improving the anti-ultraviolet aging properties of flame retardant modified epoxy resin.
