PVA 纤维改性聚丙烯酸酯亲水涂层的制备及性能
Preparation and properties of polyacrylate hydrophilic coating modified with PVA fiber
摘要
Abstract
In order to further improve the mechanical properties as well as continuous hydro‐philicity of polyacrylate ,water‐based PVA fibers were used to crosslinkedly modify polyacry‐late .Through the experiments ,blending method to use the aqueous PVA fibers was ex‐plored ,which should be used without heating and coat immediately when mixing .After the selecting of PVA fibers among the three aqueous PVA fibers ,sy‐6 was selected to modify the polyacrylate ,the effect of amount of sy‐6 on hydrophilic properties ,water resistance ,alkali resistance ,salt spray resistance ,tensile strength ,elongation at break and impact of flexibility were explored .The test results showed that when the amount of sy‐6 is added to 1 .5% ,the continuous contact angle reduces to 30 ° ,and the tensile strength increases to 5 .98 M Pa and elongation at break to 234 .55% .What′s more , the coating of modified polyacrylate per‐formes good flexibility ,and there was no exception in 1 mm shaft rod test .关键词
