摘要
本文介绍了一种用不饱和聚酯树脂、水泥、砂、水及化学助剂等配制而成的新型砂浆。研究了这种聚酯水泥砂浆的配制方法,基本配方与主要性能,并对这种砂浆的增强机理作了探讨。该聚酯水泥砂浆综合了聚酯和水泥的优点,其物理力学性能高于国内现有的相近的材料,且配制简单,其可操作时间、颜色等可任意调节,成本也较低,有良好的耐酸碱性,因此是一种新型的聚酯水泥复合材料,可考虑用于建造防腐地坪,也可用于修补混凝土与水泥制品的外观缺陷及混凝土路面的快速修补、化工管道、容器在运营状态下的堵漏等。
This paper introduced a new type of mortar which is prepared from unsaturated polyester resin, cement, sand, water, auxiliaries, etc. The preparation method, mixing ratio and main performances of this polyester-cement mortar were investigated. In addition, the reinforcing mechanism of this mortar was discussed. This polyester-cement mortar combines the advantages of cement with that of polyester resin. This mortar can be easily prepared with better mechanical performances than those of current domestic similar mortar materials. Besides, its colour and operating time can be regulated and the cost of the mortar is also lower. Furthermore, this mortar has higher chemical stability and can be used to construct aseptic floor, mend appearance defect of the cement and concrete product, rapidly patch concrete pavement and plug chemical vessel or pipe line, etc.
