Flame-retardant sound-insulation polyurethane foam as well as preparation method and application thereof
The invention discloses flame-retardant sound-insulation polyurethane foam as well as a preparation method and application thereof. The flame-retardant sound-insulation polyurethane foam is prepared from raw materials including a component A and a component B, the component A is prepared from the following components in parts by mass through reaction: 30 to 50 parts of polyether polyol-1, 10 to 20 parts of formaldehyde, 0 to 10 parts of paraformaldehyde, 20 to 30 parts of melamine, 1 to 10 parts of furfuryl amine and 2 to 8 parts of bismaleimide; the component B is prepared from the following components in parts by mass through reaction: 25 to 45 parts of polyether polyols 2, 5 to 20 parts of isocyanate 1 and 40 to 70 parts of isocyanate 2. The foam material prepared by the invention has the advantages of high foam aperture ratio, fine foam holes, high foam strength, excellent flame retardant property and the like, can be quickly formed by a one-step method, is high in curing speed, can be formed by spraying, and is suitable for sound insulation requirements of complex shapes under different construction conditions.
本发明公开了一种阻燃隔音聚氨酯泡沫及其制备方法和应用，所述阻燃隔音聚氨酯泡沫制备原料包括组分A和组分B；所述组分A由包括以下质量份的各组分反应得到：30‑50份聚醚多元醇‑1、10‑20份甲醛、0‑10份多聚甲醛、20‑30份三聚氰胺、1‑10份糠胺、2‑8份双马来酰亚胺；所述组分B由包括以下质量份的各组分反应得到：25‑45份聚醚多元醇‑2、5‑20份异氰酸酯1、40‑70份异氰酸酯2。本发明制备的泡沫材料具有泡沫开孔率高，泡孔细腻、泡沫强度高，并且阻燃性能优异等优势，并且可以一步法快速成型，固化速度快、可喷涂成型，适用于不同施工条件下，复杂形状的隔音需求。
