聚丙烯酸酯/纳米ZnO复合皮革涂饰剂微结构与性能调控

针对聚丙烯酸酯/纳米ZnO复合皮革涂饰剂研究过程中性能调控的盲目性，在前期研究基础上，提出采用不同结构的纳米ZnO制备系列聚丙烯酸酯/纳米ZnO复合皮革涂饰剂，系统研究制备过程中、成膜过程中及涂饰过程中纳米ZnO结构的变化、纳米ZnO的分布状态、聚丙烯酸酯乳胶粒结构的变化，通过归纳分析纳米ZnO结构与聚丙烯酸酯/纳米ZnO复合皮革涂饰剂所成薄膜及涂饰后革样各项性能间相互影响的规律，建立纳米ZnO结构与复合皮革涂饰剂性能间的相关性。其中所涉及的涂饰过程中纳米ZnO结构及聚丙烯酸酯乳胶粒结构的变化和纳米ZnO结构与复合皮革涂饰剂性能相关性的研究尚未见文献报道。期望通过本研究为高性能聚丙烯酸酯/纳米ZnO复合皮革涂饰剂的设计与性能调控提供理论依据。

To solve the blindness of performance regulation and control during the research of polyacrylate/nano-ZnO composite leather finishing agent, a serials of polyacrylate/nano-ZnO composite for leather finishing are prepared with different structures of ZnO nanoparticles based on the previours research. The structure change rules of ZnO nanoparticles and polyacrylate latex particles, distribution of ZnO nanoparticles during the preparation, film-forming and finishing processes of polyacrylate/nano-ZnO composite leather finishing agents are studied systematically. The relationship between the structure of ZnO nanoparticles and the properties of polyacylate/nano-ZnO composite leather finishing agents are built by analyzing and summarizing the influence of the structure of ZnO nanoparticles on properties of films and leather finished by polyacrylate/nano-ZnO composite. In which, the structure change of ZnO nanoparticles and polyacrylate latex particles during finishig processes of polyacrylate/nano-ZnO composite leather finishing agents and the relationship between the structure of ZnO nanoparticles and the properties of polyacrylate/nano-ZnO composite leather finishing agents have not been reported. These work will offer theoretical foundation to designing and regulating properties of high quality polyacrylate/nano-ZnO composite leather finishing agent.
