外保温系统砂浆是一种聚合物增强的水泥基预配制干混柔性粘结砂浆。它是以水泥、石英砂、德国进口聚合物胶粘料配以多种添加剂混合机均混而成，和掺入 传统建筑胶的砂浆相比具有优良的柔韧性和粘结性能，以及良好的抗下垂性、保水性、耐水性以及简单方便的可操作性，增强了基材与EPS保温板之间的粘结强 度，增强了拉伸强度，防止空鼓。直接加水，施工方便，操作简单，工效高。无毒、无嗅、不燃、不伤人体，不含挥发性溶剂，属绿色环保产品。
External thermal insulation system mortar is a kind of polymer reinforced cement-based precast dry-mixed flexible bonding mortar. It is made of cement, quartz sand, German imported polymer adhesives mixed with various additives. Compared with the mortar mixed with traditional building adhesives, it has excellent flexibility and bonding performance, as well as good droop resistance, water retention, water resistance and simple and convenient maneuverability. It enhances the bonding strength between the base material and EPS insulation board, and enhances the tensile strength. Degree, prevent empty drum. Direct water addition, convenient construction, simple operation, high efficiency. Non-toxic, odorless, non-flammable, non-harmful to human body, no volatile solvents, is a green environmental protection product.
It is suitable for bonding EPS polystyrene insulation board, XPS polystyrene extrusion board, GRC board, ceramsite board and cement board with concrete, brick block and aerator on external and internal insulation system. At the same time, it is also suitable for the thermal insulation wall with larger shrinkage and the thin marble and gypsum board with smoother surface. Smooth, firm, clean and dry. For new construction projects, the concrete residue and release agent of the wall must be cleaned up, the parts with poor smoothness of the wall should be chiseled or repaired, the loose parts of the surface must be removed, and the newly plastered base should be hardened and dried before construction.
保温粘结砂桨条粘法：先用齿状镘刀将搅拌好的外保温系统砂浆胶粘剂均匀地涂抹在聚苯板或挤塑板上，然后用齿状抹子在粘结砂浆上面梳理出条状纹，将保温板粘贴在墙面上，轻柔 均匀地按压板面使之粘结牢固，随时用2m靠尺检查平整度和垂直度。粘板时注意清除板边溢出的砂桨，使板与板之间无碰头灰。点框法：用抹灰刀将搅拌好的外保 温系统砂浆胶粘剂均匀涂抹在保温板边缘上形成边框，然后在板面上均匀分布5个高于边框的粘结点，最后按上述方法将聚苯板或挤塑板粘到墙面上用靠尺靠平。设 计要求采用机械铆固件固定聚苯板或挤塑板时，铆固件安装应最少在粘结砂浆使用3天以后。
Thermal insulation bonding sand paddle sticking method: first, mix the mortar adhesive of external insulation system evenly on the polyphenyl board or extruded board with toothed trowel, then comb out the stripes on the bonded mortar with toothed plaster, paste the insulation board on the wall, press the board surface gently and evenly to make the bonding firm, check the flatness and verticality with 2m ruler at any time. Attention should be paid to removing the overflowing sand paddles at the edge of the board so that there is no contact ash between the board and the board. Point-frame method: The mortar adhesives of external thermal insulation system stirred by plastering knife are evenly applied on the edge of thermal insulation board to form a border, then five bonding points higher than the border are evenly distributed on the board surface. Finally, according to the above method, the polyphenyl board or the extruded board are bonded to the wall surface and leveled with a ruler. The design requires that when mechanical riveting firmware is used to fix polyphenyl board or extruded board, the riveting firmware shall be installed at least after 3 days of use of bonded mortar.
The construction temperature is above 5 C. It is strictly forbidden to add sand, cement and other additives without authorization. The freeze-proof type should be adopted below O C (winter application is not recommended to ensure the stability of the whole system). Mixed mortar should be used up within 2 hours, and solidified propeller should not be reused. Storage and transportation should be moistureproof and sunscreen.
