| 摘 要： | 采用硫酸溶液处理天然橡胶表面以改善其粘结性能。通过力学性能测试、电子扫描电镜（SEM）、能量分析光谱（EDX）、接触角分析等研究了不同处理时间对天然橡胶表面粘结性能的影响。随着处理时间的延长,天然橡胶表面的接触角先减小后增大;SEM测试结果表明经过硫酸处理后天然橡胶表面的粗糙度和微裂纹增多,有利于胶粘剂的润湿和渗透;EDX测试结果显示,橡胶表面氧元素含量增多,表明引入了含氧极性基团—C O、—COO-等。随着处理时间的延长,T-型剥离强度先增大后减小,用质量分数为80%的H2SO4溶液处理15 min时,剥离强度达到最大值10.67 kN/m。硫酸处理可改善天然橡胶表面的表面形貌、化学性质及其润湿性,有利于粘结强度的提高,从而提高天然橡胶的粘结性能。 |
