(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.

在建筑行业领域，装配式建筑成为建筑行业的热门方向之一。其组件组合后的密封情况对建筑影响很大。本文利用陶土为矿粉为填料，制备MS密封胶。研究了陶土尾矿粉的添加量对MS密封胶力学性能的影响，以及在胶体中的分散情况。研究结果表明:陶土尾矿粉对MS密封胶有明显的补强作用，当添加量为基体重量的1.4倍时，其MS密封胶最大拉伸应力为U.1 MYa;当添加量为基体重量的1.2倍时，其MS密封胶的断裂伸长率为1148%。

在低碳大环境的背景下，绿色建筑是建筑行业转型升级的主要方向装配式建筑成为了建筑行业的热门组件组合后的密封对装配式建筑至关重要目前，应用于装配式建筑中的MS密封胶主要有三种类型，分别是聚氨醋类、硅酮类和硅烷改性聚醚类聚氨醋类MS密封胶由于有游离的异氰酸醋存在，使用后在固化过程中易产生气泡，使其力学性能收到影响，因此限制了它的适用范围硅酮类MS密封胶相比于其他两类MS密封胶，使用时间久了会有硅油产生，其粘结性受到影响，因此其耐久性差，可涂饰性较差，同时建筑物表面的美观程度也会受到影响相比于聚氨醋MS密封胶和硅酮MS密封胶，硅烷改性聚醚密类的MS密封胶使用过程中没有气体产生，不会有硅油溢出，更绿色环保，展现出良好的力学性能，涂饰性能以及耐污性能等优点，逐渐成为国内外新型MS密封胶的主要发展方向之一。

本文利用陶土尾矿粉为填料，制备MS密封胶研究了陶土尾矿粉的添加量对MS密封胶力学性能的影响，以及在胶体中的分散情况。

将100 g的硅烷改性聚醚( MS)预聚物，55 gPPG3000,90 g预处理的陶土尾矿粉(相对于MS为90phr)加人双辊行星搅拌机中，于100℃真空条件下，以50 rpm/min的速度搅拌预混合1 h。

冷却至室温后加人2.5 g KH792 ,1.5 g二月桂酸二丁锡，真空搅拌30min，随后出料，倒人模具待用

与上述方法一致，分别制备80 p帅,100 p帅,120php,140 php,160php和180 php陶土尾可‘粉含量的硅烷改性聚醚MS密封胶此外，将不含填料的纯硅烷改性聚醚MS密封胶作为空白组。

MS密封胶性能测试

取出制备好的试片制成哑铃形样条，按GBT528-2009中的方法，利用电子拉力机进行测试

按GBT531.1-2008方法，使用邵氏A硬度计测试样品的硬度值。

将不同含量的陶土尾矿粉填充制备的硅烷改性聚醚MS密封胶的样条在液氮中脆断，采用扫描电子显微镜(SEM)对填料的分散形貌进行观察。http://www.sdyuantai.com/
