Description

隔音防震的硬质泡沫材料 技术领域
本发明涉及一种泡沫，具体涉及一种隔音防震的硬质泡沫材料。
背景技术
聚氨酯泡沫塑料是异氰酸酯和羟基化合物经聚合发泡制成，按其硬度可分为软质和硬质两类。一般来说，它具有极佳的弹性、柔软性、伸长率和压缩强度；化学稳定性好，耐许多溶剂和油类；耐磨性优良，较天然海绵大20倍；还有优良的加工性、绝热性、粘合性等性能，是一种性能优良的缓冲材料，但价格较高。聚氨酯泡沫塑料一般只用于高档精密仪器、贵重器械、高档工艺品等的缓冲包装或衬垫缓冲材料，也可制成精致的、保护性极好的包装容器；还可采用现场发泡对物品进行缓冲包装。
硬质聚氨酯泡沫塑料具有密度小、强度高、导热系数低、隔音、隔水等特点。
为了降低噪音对我们日常生活的影响，在建筑物中，采取的措施主要是隔声和吸声。隔声就是将声源隔离，防止声源产生的噪声向室内传播。在马路两旁种树，对两侧住宅就可以起到隔声作用。在建筑物中将多层密实材料用多孔材料分隔而做成的夹层结构，也会起到很好的隔声效果。为消除噪声，常用的吸声材料主要是多孔吸声材料，如玻璃棉、矿棉、膨胀珍珠岩、穿孔吸声板等。材料的吸声性能决定于它的粗糙性、柔性、多孔性等因素。泡沫塑料也叫多孔塑料，以树脂为主要原料制成的内部具有无数微孔的塑料，具有质轻、绝热、防震、耐腐蚀的作用，广泛用做包装材料及制车船壳体等。
