摘要:
由于钛酸钾晶须比表面积大且表面能高，易团聚，会影响复合材料的分散性，因此需要对它进行表面改性处理，通过设计三因素三水平的正交实验，研究利用不同硅烷偶联剂的种类、浓度以及偶联反应时间改性后的钛酸钾晶须所抄取的密封垫片的性能，得到最优的钛酸钾晶须的表面改性方法。研究结果表明，当控制偶联反应时间为1 h，采用质量分数为3%的KH-560偶联剂时，表面处理后的钛酸钾晶须分散效果较好，表面有更多的附着物，团聚情况较轻，并且粘结性也有了很大的提高。将利用最优表面改性方法处理后得到的钛酸钾晶须用于无石棉垫片的制备中，获得的无石棉密封垫片的压缩率达到18.169%，回弹率达到47.226%，拉伸强度达到13.803 MPa，与未添加钛酸钾晶须的无石棉密封垫片相比，能够在一定程度上提高无石棉密封垫片的拉伸强度。
Abstract:
Due to the large specific surface area and high surface energy of potassium titanate whiskers, they are easier to agglomerate, which will affect the dispersion of composite materials. Therefore, it is necessary to modify the surface of potassium titanate whiskers. By designing orthogonal experiments with three factors and three levels, the performance of sealing gaskets prepared by potassium titanate whiskers modified by different silane coupling agents, concentrations and coupling reaction time, was studied, and the optimal surface modification method of potassium titanate whiskers was obtained. The results showed that when the coupling reaction time was controlled for 1 h and the mass fraction of KH-560 coupling agent was 3%, the dispersion effect of potassium titanate whiskers after surface treatment was better, and there were more attachments on the surface. Moreover, the reunion situation is relatively mild , and the adhesion was also greatly improved, the potassium titanate whisker obtained by using the optimal surface modification method will be used in the preparation of asbestos free gaskets, the obtained asbestos-free sealing gasket has a compression rate of 18.169%, the rebound rate reached 47.226%, and the tensile strength reached 13.803 MPa. Compared with non asbestos sealing gaskets without adding potassium titanate whiskers, the tensile strength of non-asbestos sealing gaskets can be improved to a certain extent.
