范文编号:HG171 范文字数:16506,页数:29 摘 要:本范文研究具有Pull-up效应的合成革涂饰配方,优化选择考察Pull-up效应蜡及配伍助剂,主要讨论了蜂蜡、聚乙烯蜡、聚丙烯蜡,蒙旦蜡助剂不同用量,对涂膜性能的影响。考察涂层的感观质量、Pull-up效应、涂膜的拉伸强度、断裂伸长率、膜耐溶剂性能等指标;通过实验得出蜂蜡、聚乙烯蜡、聚丙烯蜡等材料用于效应层涂饰,具有较好的Pull-up效应,涂饰剂再加入适量硅助剂及蜡助剂可提高涂膜的力学性能及手感,特别是断裂拉伸性能有较大的改进,且与树脂具有较好的配伍性。通过实验得出加入了聚乙烯蜡和聚丙烯蜡的配方效应最佳。 Abstract: This paper is study on the pull-up characteristic of a Synthetic leather finish Formulation. Optimization investigation Pull-up Waxes and compatibility of additives. Focused on The Membrane Performance were optimized by changing concentration of honey-wax, polyethylene wax, Polypropylene Wax, mondang wax. Sensory quality of the coating inspection, Pull-up effects, film tensile strength, elongation at break, film solvent resistance and other indicators. obtained using honey-wax, polyethylene wax, polypropylene wax and other materials used for effects layer coating has excellent Pull-up effect .Coating agent and then adding an appropriate amount of silicon additives and wax additives can improve the mechanical properties of film and feel. Tensile properties, especially fracture greatly improved, and the resin has good compatibility. The best preparation process conditions were obtained through tests .including polyethylene wax or polypropylene wax . Keywords:finishing agent;pull-up; polyethylene wax; Polypropylene Wax 目录
