摘要:以聚甲基丙烯酸甲酯(PMMA)和纳米TiO2为原料,通过基于模内扭转叠合为原理的微纳层叠共挤实验平台,制备出具有多层结构的PMMA/纳米TiO2薄膜,并对样品的微观形貌、抗紫外性能和流变性能进行了表征。结果表明,多层PMMA/纳米TiO2复合薄膜中填料分散性优于单层薄膜,层叠器中的剪切力破坏了团聚体的尺寸,增强了填料的分散性;纳米TiO2的加入使PMMA具有抗紫外性能,PMMA/纳米TiO2薄膜的紫外吸收性能随着填料含量的增加而提高,但降低了透明性,填料添加量为0.2%时,复合薄膜在中波紫外和长波紫外段的平均吸收率达到50%和37%,此时的平均可见光透过率仍能保持82%;相同纳米TiO2含量下的多层薄膜抗紫外性能优于单层薄膜,纳米TiO2增加了PMMA体系黏度,提升了熔体强度并改善了加工性能。 
Abstract:Multilayer polymethyl methacrylate (PMMA)/nano-TiO2 film was prepared by using PMMA and nano-titanium TiO2 as raw materials through a micronano multilayer co-extrusion device based on the principle of in-mold torsion. The microscopic morphology, UV resistance and rheological properties of the samples were characterized. The results show that multilayer PMMA/nano-TiO2 composite film has better dispersibility than single-layer film, because the shearing force in the stacker destroys the size of the agglomerate and enhances the dispersibility of the filler. The addition of nano-TiO2 makes the PMMA have UV resistance. The UV absorption performance of PMMA/nano-TiO2 film increases with the increase of filler content, but the transparency is reduced.When the filler is added at 0.2%, the composite film is in the middle wave UV. The average absorption rate of the long-wave ultraviolet section is 50% and 37%, and the average visible light transmittance can still be maintained at 82%. The multilayer film under the same nano-TiO2 content is superior to the single-layer film. Nano-TiO2 increases the shear viscosity of PMMA which improve the melt strength and the processing performance.
