Study on Properties of Modified Nano-ZnO/WPU Hybrid Material

Article Preview

Abstract:

Modified nanoZnO/WPU hybrid material was synthesized by three different ways in this paper, the effect of the addition method and content of modified nanoZnO on the hybrid material were discussed. The results showed that modified nanoZnO was added in polymerization process, the hybrid emulsion stability and the coating films mechanical strength all with excellent performance. The appropriate addition of nanoZnO modified by titanate coupling agent can improve the ultraviolet weatherproof, tensile strength, elongation at break even the abrasion resistance of the hybrid material. When modified nanoZnO content was 0.3%, the comprehensive performance of hybrid material was the best.
