摘要： The present invention provides a flexible polyurethane foam having good resistance to wet heat aging and resistance to ozone deterioration and a speaker edge having an excellent waterproofness comprising such a flexible polyurethane foam. As a polyol, a polyol component obtained by mixing a polyester polyol having an excellent compatibility with polyether polyol such as adipate of a long-chain alkylene glycol having at least 5 carbon atoms with a foaming agent, a catalyst, a foam stabilizer, etc. is reacted with a polyisocyanate to obtain a flexible polyurethane foam having good resistance to wet heat aging and resistance to ozone deterioration. Further, the incorporation of a specific aromatic secondary amine compound, a monofunctionally-terminated compound and an ultraviolet absorbent in the foam composition makes it possible to obtain a flexible foam having better resistance to ozone deterioration and weather resistance. The flexible foam can provide a speaker edge having a small drop of strength and elongation due to compression molding and excellent waterproofness and weather resistance in combination.
摘要翻译：本发明提供一种具有良好的耐湿热老化性和耐臭氧性的柔性聚氨酯泡沫，以及包含这种柔性聚氨酯泡沫的具有优异防水性的扬声器边缘。作为多元醇，通过将具有至少5个碳原子的长链亚烷基二醇与己二酸酯与聚醚多元醇具有优异相容性的聚酯多元醇与发泡剂，催化剂，泡沫稳定剂等混合而获得的多元醇成分与多异氰酸酯反应以获得具有良好的耐湿热老化性和耐臭氧劣化性的柔性聚氨酯泡沫。此外，在泡沫组合物中引入特定的芳族仲胺化合物，单官能封端的化合物和紫外线吸收剂可以获得具有更好的耐臭氧性和耐候性的柔性泡沫。柔性泡沫可以提供由于压缩成型而具有小的强度和伸长率的扬声器边缘，并且具有优异的防水性和耐候性。

摘要： The present invention provides a waterproof plastic foam such as waterproof polyurethane foam which can keep the inherent properties of the foam and exhibit low gas permeability and water absorption, excellent water-sealing properties and hence a stable waterproofness. A waterproof plastic foam obtained by a process which comprises foaming a foamable composition comprising a polyisocyanate, a compound containing at least two active hydrogen groups, a compound containing at least one ester bond, a catalyst, a blowing agent and a foam stabilizer, and then curing the foam is described, wherein the compound containing at least one ester bond is a product of the reaction of any one of a monocarboxylic acid having not less than 9 carbon atoms, an aliphatic dicarboxylic acid having not less than 8 carbon atoms and an alicyclic dicarboxylic acid having not less than 8 carbon atoms with a monoalcohol having not less than 10 carbon atoms, and the compound containing at least one ester bond is incorporated in an amount of from 7 to 100 parts by weight based on 100 parts by weight of the compound containing at least two active hydrogen groups. A waterproof plastic foam obtained by a process which comprises foaming a foamable composition comprising a polyisocyanate, a compound containing at least two active hydrogen groups, a compound containing ester bonds, a catalyst, a blowing agent and a foam stabilizer, and then curing the foam is also described, wherein the compound containing ester bonds is made of oleic acid and one component selected from the group consisting of butadiene polyol, adduct of bisphenol A with propylene oxides and castor oil, and the compound containing ester bonds is incorporated in an amount of from 7 to 100 parts by weight based on 100 parts by weight of the compound containing at least two active hydrogen groups.
