在聚乙烯醇(PVA)的醋酸乙烯酯(VAc),丙烯酸丁酯(BA)体系中,讨论了在无酸及顺丁烯二酸酐(MAn)、或丙烯酸(AA)、或α—甲基丙烯酸(MAA)的加入等四种情况下,所得乳胶粒径大小及分布、流变性、离心稳定性、膜的耐水性、剥离强度等性能的变化,所得数据表明,酸的加入使得乳胶体系的粒径变大,AA的加入使体系粘度增大,稳定性增强,MAn的加入使其乳胶对PVC塑料具有较强的粘接力。
In the VAc and BA systems of polyvinyl alcohol (PVA), it is discussed that in the absence of acid and maleic anhydride (MAn), or acrylic acid (AA), or alpha-methyl Acrylic acid (MAA) and other four cases, the size and distribution of the resulting latex particle size, rheological properties, centrifugal stability, water resistance, peel strength and other properties of the film, the data obtained show that the addition of acid latex system The particle size becomes larger, the viscosity of the system increases with the addition of AA, and the stability is enhanced. The addition of MAn makes the latex have strong adhesion to PVC plastic.
