AI Technical Summary
Technical Problem
Existing nylon materials are prone to aging under ultraviolet radiation, exhibiting yellowing, brittleness, and cracking. Furthermore, traditional ultraviolet absorbers suffer from problems such as poor migration, compatibility, and heat resistance.
Method used
Rare earth aluminate coupling agents were synthesized by using rare earth oxides and pyrophosphates to modify the surface of nano-titanium dioxide, and then melt-blended with a nylon matrix to form a rare earth composite titanium dioxide anti-UV nylon material.
Benefits of technology
It improves the compatibility and dispersibility of nano-titanium dioxide with the nylon matrix, enhances the material's UV resistance and mechanical properties, and extends the material's service life.

Abstract
本发明公开了一种稀土复合二氧化钛的抗紫外尼龙材料及其制备方法，涉及功能高分子材料技术领域。本发明将稀土氧化物与焦磷酸二辛酯和三异丙氧基铝合成稀土铝酸酯偶联剂，再利用稀土铝酸酯偶联剂对纳米二氧化钛进行表面改性，最后将得到的改性纳米二氧化钛与尼龙基体熔融共混得到稀土复合二氧化钛的抗紫外尼龙材料。利用该稀土偶联剂对纳米二氧化钛进行表面改性，不仅改善了其与尼龙基体间的界面相互作用，将具有抗紫外功能的纳米二氧化钛更加稳定且均匀地与尼龙纤维结合，不易团聚，改善了复合材料的力学性能，并且由于与稀土元素的协同作用使尼龙材料具有更加持久、稳定的抗紫外性能。
