摘要
介绍了建筑外墙腻子粉的制备过程和技术性能,分析了羧甲基纤维素和聚丙烯纤维等对腻子性能的影响.结果表明:羧甲基纤维素一定程度上降低了腻子的抗压和抗折强度,但可以提高其粘结强度,聚丙烯纤维则可以有效改善硬化腻子的抗裂性.结合显微结构观察,简要讨论了羧甲基纤维素和聚丙烯纤维性能对腻子的作用机理。综合性能试验结果表明,所研制的腻子粉的各项性能均可满足建筑外墙用腻子技术指标.
The paper introduces the preparation process and the technical performance of the putty powder for exterior use and analyzes the influence of CMC and polypropylene fiber on the performance of the putty. The results show that, with the addition of CMC, both the compressive and flexural strengths of the hardened putty layers will be reduced to some extent while the binding strength will be increased. Addition of polypropylene fiber will effectively improve the anti-cracking property of the hardened putty layer. From SEM observation, the mechanism of CMC and polypropylene fiber on the performance of the putty is discussed. A synthetic test for the performance of the putty shows that the putty powder developed in the present work can meet the qualification for exterior use.
