摘　　要：根据轻质砂加气混凝土墙板的特点,提出其板缝接缝用密封胶的性能要求,并对选定密封胶进行了相关性能的研究。结果表明:与SR密封胶相比,MSPU、PU密封胶耐碱性能更优,更适合用于混凝土材料的粘结密封;MSPU密封胶兼具PU与SR密封胶的性能优点,综合性能最优;涂刷专用基层处理剂能够提高密封胶与基材的粘结性能。According to characteristics of light sand aerated concrete panels,this article puts forward performance requirements of sealant for its plate"seams,and studies on the relevant properties of selected sealants.The results show that compared with SR sealant,MSPU and PU sealant have better alkali resistance and are more suitable for bonding and sealing of concrete materials.MSPU sealant combines the performance advantages of PU and SR sealant so it has the best overall performance.The special primary treatment agent can improve the bonding perforraance between the sealant and the substrate.
