本研究分析了热量和湿气的影响polyketone-polyurethane涂层系统和基于分析提出了一个可预测的关系。聚酮是一种环境友好型材料,因为它使用一氧化碳为原料,生产廉价的。同时,具有优良的耐热性,耐冲击,耐化学性,因此非常适用于工业防水布等面料。另一方面,聚氨酯是一种涂层材料的耐磨性、耐气候性和耐油性除了防水性。防水织物的防水性能取决于缺陷的发生在涂层表面和涂层之间的粘附强度和结构。可以克服外力的界面粘附强度是由焊接方法和分层系统的结合力,从而影响防水布的生活。为了提高防水织物的耐久性,聚酮织物代替过去使用的聚酯或尼龙面料,和聚氨酯使用通常用于防水涂料。环境影响,包括温度和湿度影响polyketone-polyurethane从织物表面涂层系统。因此,使用扫描电镜观察表面属性,和静压头测试用于确定织物的涂层表面缺陷的水平。拉伸和粘附强度测试来确定涂层织物的力学性能。 The chemical changes after aging were qualitatively analyzed using FTIR, and the chemical changes of the polymer network by decomposition were measured from the results of weight reduction. The degree of damage due to the degradation of the coated surface was confirmed by weight loss value according to temperature, humidity and exposure time. The adhesion characteristics of polyketone - polyurethane coating system according to exposure environment were evaluated from the peeling strength results. Also, the behavior of adhesive force could be predicted. In conclusion, we found that temperature, moisture, and exposure time affect the interfacial adhesion of polyketone-polyurethane coating systems, and the interrelationships were partially confirmed by analyzing the results.
