(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

为了验证“双组份硅烷改性聚氨酯密封胶”嵌缝材料对防撞墙伸缩缝封缝的适用性以及耐久性，后期一年多时间里对现场实验的3条防撞墙伸缩缝进行了5次跟踪。实验后期跟踪记录见表t。

至2018年4月2日，现场实验的3条防撞墙伸缩缝均表观良好。缝宽正常，且与防撞墙伸缩缝两侧结合密实，无拉裂、开胶等缺陷情况。

依据后期跟踪记录情况，我们可以看到，现场3条实验的防撞墙伸缩缝在气温4℃和30℃的极端情况下均表现良好。说明“双组份硅烷改性聚氨酯密封胶”嵌缝材料具有超强的耐候性以及柔性，这种材料适合用作防撞墙伸缩缝的封缝材料。

双组份硅烷改性聚氨酯密封胶相较于传统聚氨酯嵌缝材料使用寿命长，有较优的经济性。见表2。注:聚氨酯综合单价二55(聚氨酯每只单价)X 3. 64+200(安装费)=400元;双组份硅酮胶综合单价二1 350(一组单价)十200(安装费)=1 550元。

由于传统防撞墙伸缩缝嵌缝材料与混凝土的结合以及追随性不强，导致经常将两侧的混凝土拉裂、甚至损坏。如图1、图2所示。简单来讲就是现有材料的柔性不足，硬碰硬导致出现此类问题，说明现有材料不适用于此类工程。双组份硅烷改性聚氨酯密封胶由于具有超强的耐候性以及柔性，所以能很好地应对混凝土热胀冷缩对混凝土结构本身所带来的损害。http://www.sdyuantai.com/
