Gypsum-based thermal insulation and sound insulation floor mortar and preparation method thereof
The invention relates to the technical field of gypsum mortar, and discloses gypsum-based heat-preservation and sound-insulation floor mortar and a preparation method thereof.The gypsum-based heat-preservation and sound-insulation floor mortar is prepared from alpha-type gypsum, a mixed foaming agent, modified polystyrene particles, closed-cell glass beads and an additive; the modified polystyrene particles are prepared from modified SiO2 fibers and a crosslinking monomer through crosslinking and emulsification processes. According to the gypsum-based heat-preservation and sound-insulation floor mortar, the alpha-type gypsum is adopted as a cementing material, cement does not need to be added, and the modified polystyrene particles, the closed-cell vitrified micro bubbles and other components are introduced, so that the floor mortar has higher absolute dry strength and good heat-preservation and sound-insulation effects, and is convenient to construct and long in service life.
本发明涉及石膏砂浆技术领域，公开了一种石膏基保温隔声地坪砂浆及其制备方法，所述石膏基保温隔声地坪砂浆包括α型石膏、混合发泡剂、改性聚苯乙烯颗粒、闭孔玻化微珠、外加剂；所述改性聚苯乙烯颗粒由改性SiO2纤维、交联单体经交联、乳化过程制备得到。本发明的石膏基保温隔声地坪砂浆采用α型石膏作为胶凝材料，无需加入水泥，且引入改性聚苯乙烯颗粒、闭孔玻化微珠等组分，可使地坪砂浆具有更强的绝干强度、良好的保温和隔声效果，且施工方便，使用寿命长。
