Polyurethane foams are described, as well as the production of such polyurethane foams by the reaction between a natural polyol, such as sucrose or a blend of mono- or disaccharides in place of the standard hydrocarbon-based polyol component, an ionic liquid or a deep eutectic solvent, a polyisocyanate and water in the presence of a suitable polyurethane forming catalyst and optionally a flame retardant, and optionally one or more components such as surfactants and/or emulsifiers. The resultant polyurethane foam can exhibit a bio-based solid content ranging from about 17% to 30%, may be formulated in a variety of foam densities for a variety of applications, and in the instance where a flame retardant has been added in an appropriate amount, exhibits a high degree of fire and burn resistance, as exhibited by the flame spread index and/or the smoke spread values.
本文介绍了聚氨酯泡沫塑料以及聚氨酯泡沫塑料的生产方法,即在适当的聚氨酯成 形催化剂和阻燃剂以及表面活性剂和/或乳化剂等一种或多种成分存在的情况下,天然 多元醇(如蔗糖或单糖或双糖混合物)代替标准的碳氢化合物多元醇成分、离子液体 或深共晶溶剂、多异氰酸酯和水发生反应。由此产生的聚氨酯泡沫的生物基固体含量约为 17% 至 30%,可配制成各种泡沫密度,适用于各种应用,在添加适量阻燃剂的情况下,具有很高的阻燃性,如火焰蔓延指数和/或烟雾扩散值所示。
