Anti-noise sound insulation belt for road
The invention provides an anti-noise sound insulation belt for a road. The anti-noise sound insulation belt is obtained by filling a sound insulation and absorption layer between two layers of metal plates, and the sound insulation and absorption layer is formed by foaming polyurethane based on polytetrahydrofuran ether glycol and liquid diphenylmethane diisocyanate to form a porous foam structure, so that the product has basic sound insulation and absorption performance. Most importantly, modified mixed fibers and the gamma-aminopropyltriethoxysilane modified vesuvianite powder are introduced, are uniformly distributed in a system and have good compatibility with polyurethane, so that the sound insulation and absorption effects of the product are further improved, and meanwhile, the mechanical properties of the product are guaranteed.
本发明提供了一种公路用防噪隔音带，是通过在两层金属板之间填充隔声吸音层得到，其中隔声吸音层是基于聚四氢呋喃醚二醇、液体二苯基甲烷二异氰酸酯的聚氨酯发泡，形成多孔泡沫结构，使得产品具有基本的隔声吸音性能。最重要的是，引入了改性混合纤维和γ‑氨丙基三乙氧基硅烷改性火山石粉，两者在体系中均匀分布且与聚氨酯具有良好的相容性，进一步提高了产品的隔声吸音效果，同时保证了产品的力学性能。
