Polymer bonded mortar is mainly made of cement, quartz sand, polymer binder and a variety of additives by mechanical mixing evenly. This material is not only used for bonding thermal insulation board, such as polystyrene board and rock wool board, extruded board and other thermal insulation board of the inner wall, outer wall and ceiling bonding, but also has excellent water resistance, freeze-thaw resistance, aging resistance, and good enhancement of sag resistance, water retention, water resistance. Its construction method is simple and can be directly added water after mixing evenly, and the mortar after construction has good adhesion and fast curing time, which can effectively prevent loosening, falling and deformation caused by unexpected external forces after bonding.
