    粘结砂浆(Bonded mortar

    一、产品用途:

     用于外墙保温系统中聚苯板,挤塑板,保温一体板,水泥发泡板等的粘贴。

    二、 产品特点:

    1. 该产品无毒无味、安全环保

    2. 施工方便,现场加适量水配制成浆状即可施工。

    3. 保水性能好,粘结强度高,施工中不滑坠

    4. 具有优良的耐候性、抗冲击和防裂性能 

    三、粘结砂浆执行标准:

    JG 149-2003《膨胀聚苯板薄抹灰外墙外保温系统》

    四、施工方法:

        基层处理:基层表面粉尘、油污必须清除干净,以免影响粘结强度。

    用水将粘合剂调成厚糊状,水为1,干粉为44.5理论用量当涂层厚度为35mm时,约46kg/m2将粘合剂充分搅拌均匀,静置510分钟,粘合剂会变稠,此时再稍后加搅拌即可使用。将拌匀后的保温板专用粘合剂用泥板涂抹在保温板背面或混凝土基层面上,粘贴时拍实铺平,拨正,擦清板面。

    五、技术指标:

    项    目性能指标

    拉伸粘结强度/Mpa

    (与水泥砂浆)

    未处理≥0.6
    浸水处理≥0.40

    拉伸粘结强度/Mpa

    (与膨胀聚苯板)

    未处理≥0.10,破坏界面在膨胀聚苯板上
    浸水处理
    可操作时间/h≥2
    抗裂性5mm以下无裂纹


    六、注意事项:

      1、施工温度5℃-35℃,风力不大于5施工过程中应避免雨淋

      2、拌好的物料应在2小时内用完,忌再次搅拌或加入水和其它材料搅拌。

    3未开封保存阴凉干燥处,保质期6个月。

    Product use:

    It is used for pasting polystyrene board, extruding board, thermal insulation board, cement foamed plate and so on in exterior wall insulation system.

     

    Product features:

    1. the product is nontoxic, tasteless, safe and environmentally friendly

    2. the construction is convenient, and the site plus a proper amount of water can be made into slurry.

    3. water retention property is good, bond strength is high, no slippery fall during construction

    4. has excellent weatherability, impact resistance and crack resistance.

     

    Construction methods:

    Base treatment: the surface dust and oil pollution of the base surface must be cleaned, so as to avoid the bond strength.

    The binder is thickened by water. The water is 1 and the dry powder is 4 to 4.5. When the theoretical content is about 3 6kg/m2, the coating is about 4 to 5mm. The adhesive is fully stirred evenly, and the adhesive is thickened for 5-10 minutes. At this time, the mixture will be thickened later. Will mix the insulation board with special adhesive mud plate onto the insulation board or the back of the concrete base surface, paste compacting paving, lining, wipe the surface clean.

    Matters needing attention

     

    1. the construction temperature of 5 DEG C - 35 DEG C, the wind is not more than 5, in the construction process should avoid the rain;

    2. the mixed material should be used in 2 hours, and should not be stirred again or add water and other materials.

    3. unsealed and dry place is not opened, and the shelf life is 6 months.
