Abstract

本发明涉及一种苯乙烯/异戊二烯共聚物类阻尼材料，其由包括苯乙烯/异戊二烯三嵌段共聚物和石油树脂经共混、压片制得。与现有阻尼材料相比，本发明所说的阻尼材料具有成本低、适用温度范围宽和耐候性好等优点。

Description

苯乙烯/异戊二烯共聚物类阻尼材料
技术领域
本发明涉及一种阻尼材料，具体地说，涉及一种含苯乙烯/异戊二烯三嵌段共聚物(SIS，S为聚苯乙烯链段，I为聚异戊二烯链段)的阻尼材料。
背景技术
阻尼材料是基于高聚物的粘弹性，在其玻璃化转变区域内，由分子链运动产生的内摩擦将外场作用的机械能或声能部分地转变为热能散逸，而具有减振、降噪作用的功能材料。其被广泛地用于宇航事业、交通运输、机械设备、建筑工程及日常生活等领域。
一般均聚物的玻璃化转变温度的范围比较窄，产生有效阻尼的温度范围约为玻璃化转变温度(Tg)的±10～15℃，材料的使用温度范围窄且不可控。不能很好地满足实际使用的需要。因此，研制使用温度范围较宽且可控的阻尼材料成为本领域迫切需要解决的技术问题。
发明内容
本发明目的在于，提供一种具有宽使用温度范围且可控的阻尼材料。
本发明是在具有极性侧基的高分子量化合物中添加极性有机低分子量化合物，形成一种均匀分散的分子复合体。利用高分子与低分子的相互作用呈现出高阻尼特性，同时拓宽了阻尼材料使用温度范围且使温度范围可控。
本发明所说的阻尼材料由包括下列原料经共混、压片制得：
SIS共聚物                          100质量份数
石油树脂                           1～250质量份数
其中：所述的石油树脂为C5脂肪烃树脂、C9芳香烃树脂、氢化C9芳香烃树脂或C5脂肪烃树脂与C9芳香烃树脂共聚树脂，优选E1102石油树脂、E1401石油树脂或ECR806石油树脂，石油树脂优选的用量50～250质量份数，最佳为100～200质量份数。
上述原料均为市售品。
附图说明
图1是SIS3460/ECR806＝100/100动态力学测试分析图谱；
图2是SIS3460/E1102＝100/100动态力学测试分析图谱；
图3是SIS3460/E1401＝100/150动态力学测试分析图谱；
图4是SIS3520/ECR806＝100/100动态力学测试分析图谱；
图1～4中：横轴表示温度，纵轴表示损耗因子(Tanδ)，Tanδ＝E”/E’，E”-损耗模量，E’-弹性模量。
具体实施方式
在Φ160双辊开炼机(152×305mm)上制备混炼胶，辊筒速比为1∶1.42；按上述比例加入SIS橡胶、石油树脂，出片后，采用电加热平板的25t液压平板硫化机制得本发明所说的阻尼材料。
本发明采用石油树脂来改善SIS的阻尼性能、同时可通过改变添加剂的量和种类来调节阻尼材料的适用温度范围，从而满足不同需求。与现有阻尼材料相比，本发明所说的阻尼材料具有成本低、适用面广和耐候性好等优点。
下面通过实施例对本发明作进一步阐述，其目的在于能更好理解本发明的内容。应理解，所举之例不应视为对本发明保护范围的限定：
                        实施例1
100克SIS(牌号3460)橡胶在双辊开炼机上混入100克ECR806石油树脂，采用电加热平板的25t液压平板硫化机制备2mm厚片状材料试样，采用动态力学分析仪对进行动态力学测试分析。采用该配方的SIS橡胶材料的动态力学测试分析，测试条件：频率10Hz，温度-50℃～120℃，升温速率2℃/min，采用拉伸夹具(下同)，结果图1。由图1可以看出，该材料的损耗因子峰值为1.59，峰值位于14℃；损耗因子大于0.5的温度范围是-20.8℃～44.8℃。
                        实施例2
100克SIS(牌号3460)橡胶在双辊开炼机上混入100克E1102石油树脂，采用电加热平板的25t液压平板硫化机制备2mm厚片状材料试样，采用动态力学分析仪对进行动态力学测试分析。结果见图2。由图2可以看出，该材料的损耗因子峰值为1.00，峰值位于21.8℃；损耗因子大于0.5的温度范围是-7.1℃～61.1℃。
                         实施例3
