甲乙酮肟封闭水性聚氨酯/聚乙烯醇复合材料的制备及性能
Preparation and characterization of methyl ethyl ketoxime blocked waterborne polyurethane/polyvinyl alcohol composite
摘要
Abstract
Anionic methyl ethyl ketoxime-blocked waterborne polyurethane (ABPU) emulsion was prepared from the main raw materials of isophorone diisocyanate (IPDI),polyester diol (PCL 1000),1,4-butanediol (BDO) and dimethylol propionic acid (DMPA),using methyl ethyl ketoxime (MKEO) as the blocking agent.After that,ABPU/PVA composites were prepared by blending ABPU emulsions with PVA solution and characterized by using Fourier transform infrared spectroscopy (FT-IR),TEM,tensile testing,water contact angle measurement,viscosity and Thermogravimetric Analysis (TGA).The effects of content of PVA on properties of ABPU/PVA composites were also studied.The results showed that strong hydrogen bonding action existed between two components.When w(PVA) was 12%,the viscosity of ABPU/PVA composites emulsion was up to 159.5 mPa·s,the film had excellent thermal stability and water resistance,pencil hardness reached 2 H,adhesive force grade reached 0 level and the impact resistance was up to standard.Furthermore,the tensile strength of film was to 49.8 MPa,improved about 79.13% compared with ABPU(27.8 MPa).关键词
