摘要
无机纳米材料改性PVC (polyvinyl chloride，聚氯乙烯)树脂，用以改善PVC的力学性能，近年来成为了研究的热点。用纳米无机材料改性的目的是为了增强材料的强度、韧性、降低生产成本等。改性的方法分为物理改性和化学改性两种，物理改性又分为共混改性和填充改性两种，本实验选择的是以填充改性为实验方法，添加的加工助剂主要为增塑剂、抗冲击改性剂、润滑剂、热稳定剂。
本文提出了，添加无机纳米TiO2使PVC塑料增强增韧的实验方法。试想通过这个方法，改善PVC塑料的拉伸强度、冲击强度等性能。依据材料所需的要求设计了实验过程。最后通过拉伸实验、冲击实验、维卡软化点温度的测定和低温试验，证明了添加纳米TiO2对材料力学性能的影响，并找出纳米TiO2对PVC材料性能改进的一些规律。
研究结果表明：选择适当的加工助剂，加入纳米TiO2后PVC的强度和韧性都得到了改善，从而达到了PVC改性的目的。

Inorganic nanomaterials modified PVC (polyvinyl chloride PVC) resin, to improve the mechanical properties of PVC, in recent years has become a hot research. Nano-modified inorganic materials is designed to enhance the strength, toughness, and reduce production costs. Modified method is divided into physical and chemical modification modified two, physical modification is divided into modified and filling two, The experiment is based on the choice of filling method, add the processing aids primarily for plasticizers, impact modifiers, lubricants, heat stabilizers. This paper proposes the addition of inorganic nano-TiO2 PVC plastic Reinforced experimental methods. Just by this method, improve PVC plastics tensile strength, impact strength properties. Materials based on the requirements for design of the experimental process. Finally, tensile, impact experiments, Vicat softening point temperature and low temperature in the test, proved that the addition of TiO2 to the mechanical proper
