Low-voc polyvinyl chloride plastic material and preparation method thereof

The invention discloses a low-voc polyvinyl chloride plastic material and a preparation method thereof, and belongs to the technical field of modified plastics. The low-voc polyvinyl chloride plastic material is prepared from the following components: porous polyvinyl chloride particles, nano TiO2, cellulose nanocrystals, sodium lignin sulfonate, a rubber wear-resistant agent, calcium stearate, polyol wax, a phosphate ester antioxidant and calcined kaolin. Porous polyvinyl chloride particles are selected, nano TiO2, cellulose nanocrystals and sodium lignin sulfonate are adaptively selected to be compounded as a voc inhibitor according to the porous polyvinyl chloride particles, through ball milling treatment, the release amount of voc can be remarkably reduced, the environmental protection property is improved, and good application prospects are achieved. 本发明公开了一种低voc聚氯乙烯塑胶料及其制备方法，属于改性塑料技术领域。本发明的低voc聚氯乙烯塑胶料包括以下成分：多孔聚氯乙烯颗粒、纳米TiO2、纤维素纳米晶体、木质素磺酸钠、橡胶耐磨剂、硬脂酸钙、多元醇蜡、磷酸酯类抗氧剂、煅烧高岭土。本发明选择多孔聚氯乙烯颗粒，并针对多孔氯乙烯颗粒适应性的选择纳米TiO2
