摘要

以丙烯腈(AN)、甲基丙烯酸甲酯(MMA)、醋酸乙烯酯(VAC)为壳体单体，i-戊烷为核心发泡剂，采用悬浮聚合法制备了一种泡沫涂料用热膨胀微球(tem)。研究了水溶液添加剂氯化钠(NaCl)对tem尺寸和分布的影响，以及交联度、i-戊烷用量和单体质量比对tem膨胀性能、膨胀温度和耐溶剂性的影响。结果表明:NaCl用量接近饱和溶解度(30%)，交联剂用量和烷烃用量分别为0.09%和7.4%，AN/MMA/VAC质量比分布均匀，耐溶剂性好，在110~120℃下膨胀直径比为5倍，满足皮革或合成革泡沫涂料的应用要求。

Preparation and Properties of Thermally Expandable Microspheres for Foam Coating

A type of thermally expandable microspheres (TEMs) for foam coating was prepared by suspension polymerization with acrylonitrile (AN), methyl methacrylate (MMA), vinyl acetate (VAC) as shell polymer monomers and i-pentane as core foaming agent. The effects of an aqueous additive (Sodium Chloride, NaCl) on the size and distribution of TEMs, and the effects of crosslinking degree, i-pentane dosage and monomer mass ratio on the expansion property, expansion temperature and solvent-resistance of TEMs were investigated. The results showed that when the dosage of NaCl was close to the saturation solubility (30%), the dosage of crosslinking agent and alkane were about 0.09% and 7.4%, and the mass ratio of AN/MMA/VAC w rm distribution and good solvent resistance, the expansion diameter ratio was 5 times under 110~120 C, which meets the application requirements for foam coating of leather or synthetic leather.
