Description

一种具有阻燃性的磁性丁基胶阻尼片
技术领域
本发明涉及一种具有阻燃性的磁性丁基胶阻尼片，属于阻尼片技术领域。
背景技术
阻尼片又叫胶泥或者阻尼块，是贴在车身内表面的一种粘弹性材料，紧贴着车身的钢板壁上，主要是为了起到减少噪声、减少震动的作用，也就是说起到阻尼作用。所有小轿车里都安装有阻尼片，如奔驰、宝马等品牌汽车。此外，航天飞行器、飞机等其他需要减震降噪的机械也会用到阻尼片。现在的汽车阻尼片在装配时，先将阻尼片准确粘贴在车体钣金件特定位置上，再开始装配，由于钣金表面有灰尘、油污，阻尼片无法粘贴牢固，导致阻尼片容易掉落，影响装配进度。因此，设计一种具有阻燃性的磁性丁基胶阻尼片，它增加磁粉及阻燃剂，使其具有一定的磁性及阻燃效果，装配时更加便利，也能提高一定的安全性。
发明内容
本发明所要解决的技术问题在于：提供一种具有阻燃性的磁性丁基胶阻尼片，它解决了目前汽车阻尼片在安装时，无法粘贴牢固，影响安装效率的问题。
本发明所要解决的技术问题采取以下技术方案来实现：
一种具有阻燃性的磁性丁基胶阻尼片，它由以下组分按照质量百分比制作而成：丁基橡胶9-15％，聚异丁烯10-17％，碳五树脂2.5-4％，磁粉54-70％,碳酸钙3-4％，阻燃剂4-7％。
作为优选实例，所述磁粉为60％。
添加的磁粉经过26mT充磁后，使阻尼片产生磁性，对钣金有一定的吸附力，从而保证在钣金被污染的情况下，阻尼片能正常的装配，且因为是片状材料，可以模切为各种形状，以应对客户对阻尼片形状上的各种要求。
本发明的有益效果是：它在配方中增加了磁粉及阻燃剂，磁粉能够让阻尼片吸附在钣金表面，不会因为钣金表面的灰尘和油污，出现粘贴不牢的现象，装配时更加便利；阻燃剂能提高一定的安全性。
具体实施方式
为了对本发明的技术手段、创作特征、达成目的与功效易于明白了解，下面进一步阐述本发明。
实施例1
一种具有阻燃性的磁性丁基胶阻尼片，它由以下组分按照质量百分比制作而成：丁基橡胶12％，聚异丁烯16％，碳五树脂3.5％，磁粉60％,碳酸钙3.5％，阻燃剂5％。
制备方法：将12％丁基橡胶在捏炼机中捏炼，15-20分钟后加入3.5％碳五树脂，搅拌5分钟后加入60％磁粉，搅拌20分钟后加入3.5％碳酸钙和5％阻燃剂，10分钟后，加入16％聚异丁烯，15分钟后出料，经过挤出机成型，单面覆0.2mm厚铝箔，即得上述带有磁性及阻燃性的丁基阻尼胶片。
实施例2
一种具有阻燃性的磁性丁基胶阻尼片，它由以下组分按照质量百分比制作而成：丁基橡胶15％，聚异丁烯14％，碳五树脂3％，磁粉60％,碳酸钙3.2％，阻燃剂4.8％。
制备方法：将15％丁基橡胶在捏炼机中捏炼，15-20分钟后加入3％碳五树脂，搅拌5分钟后加入60％磁粉，搅拌20分钟后加入3.2％碳酸钙和4.8％阻燃剂，10分钟后，加入14％聚异丁烯，15分钟后出料，经过挤出机成型，单面覆0.2mm厚铝箔，即得上述带有磁性及阻燃性的丁基阻尼胶片。
实施例1与实施例2样品比较，实施例1胶料相对于实施例2胶料内聚力较小，胶料更粘，说明丁基胶含量与胶料强度成正比，聚异丁烯含量与胶初粘性成正比。
它在配方中增加了磁粉及阻燃剂，磁粉能够让阻尼片吸附在钣金表面，不会因为钣金表面的灰尘和油污，出现粘贴不牢的现象，装配时更加便利；阻燃剂能提高一定的安全性。
以上显示和描述了本发明的基本原理和主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入本发明要求保护的范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
