The invention discloses a titanium dioxide-based UV-resistant nylon 66 resin and a preparation method thereof. The invention discloses a titanium dioxide-based UV-resistant nylon 66 resin and its preparation method, wherein the nylon 66 resin comprises a matrix, and the matrix is mainly composed of nylon 66, Dispersant, ultraviolet absorber, antioxidant, modified additive, glass fiber and other components are prepared, wherein the modified additive includes modified silicon particles, modified ceria, titanium dioxide and dopamine, and modified silicon particles are Crystalline silicon particles are the main body. Crystalline silicon particles are inorganic particles with high refractive index, which can refract ultraviolet rays and improve the anti-ultraviolet performance of the finished product. The present invention has reasonable process design, suitable component distribution ratio, and the prepared resin material has excellent anti-ultraviolet performance and excellent mechanical properties, can be applied to various fields, and has high practicability. |
