    • The present invention relates to a preparing method of polyols and polyurthane, polyurethaneforms using the same by depolymerizing the polyester, polyamide and polyurethane with the polymeric fatty acid monopoly hydroxyl alcoholide, and additionally react with the polybasic acid, polyol and amine to prepare acid value of 0.5~lDKOH/g, hydroxyl value of 10~500DKOH/g, and amine value of l~50DKOH/g in polyol, and polyurethane and polyurethaneforms using the same. This is to transform the double bond of the unsaturated fatty acid from the component of the oils and fats in conjugate double bond to induce the Diesl-Alder reaction, and with the improvement of the reactivity to form stability combination in chemical structure to prevent the separate leaching appearance of fatty and fatty oil from the final product, and having the fine compatibility with the polyether-polyol as well as transparent and storage stability. Furthermore, it has 100% of solid with very low viscosity at the room temperature for easy handling while having a great reactivity with the isocyanate that this preparing polyol having excellent chemical and mechanical properties. And, in particular, by recycling the waste edible oil and waste synthetic resin that can be employed as industrially useful material for environment-friendly and economical advantage.
    • 本发明涉及多元醇和聚氨酯的制备方法,通过使聚酯,聚酰胺和聚氨酯与聚合的脂肪酸聚合的羟基醇聚合物解聚而使用聚酯,聚酰胺和聚氨酯,并且还与多元酸,多元醇和胺进行反应以制备其酸值 0.5〜lKOH / g,羟基值为10〜500DKOH / g,多元醇中胺值为1〜50DKOH / g,聚氨酯和聚氨酯成型体使用。 这是将不饱和脂肪酸的双键从共轭双键中的油和脂肪的成分转化为诱导Diesl-Alder反应,并且随着反应性的提高,形成化学结构中的稳定性组合以防止分离 从最终产品中浸出脂肪和脂肪油,并且与聚醚多元醇具有良好的相容性以及透明和储存稳定性。 此外,它具有100%的固体,在室温下具有非常低的粘度,易于处理,同时与异氰酸酯具有很大的反应性,该制备的多元醇具有优异的化学和机械性能。 特别是通过循环使用可以作为工业上有用的材料的废食用油和废合成树脂,具有环保和经济的优点。
