    • Composite materials and methods for their preparation are described herein. The composite materials include a polyurethane made from the reaction of at least one isocyanate and at least one polyol, and coal ash (e.g., fly ash). The isocyanates for these composite materials may be selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof. The at least one polyol includes lesquerella oil. The coal ash is present in amounts from about 40% to about 90% by weight of the composite material. Also described is a method of preparing a composite material, including mixing at least one isocyanate, at least one polyol, coal ash (e.g., fly ash), and a catalyst.
    • 本文描述了复合材料及其制备方法。 复合材料包括由至少一种异氰酸酯和至少一种多元醇的反应制成的聚氨酯和煤灰(例如飞灰)。 这些复合材料的异氰酸酯可以选自二异氰酸酯,多异氰酸酯及其混合物。 所述至少一种多元醇包括莱斯特雷拉油。 煤灰以复合材料的约40重量%至约90重量%的量存在。 还描述了一种制备复合材料的方法,包括混合至少一种异氰酸酯,至少一种多元醇,煤灰(例如飞灰)和催化剂。

    • The invention includes a process for preparing a flexible, water-blown polyurea foam by reacting a reaction mixture containing at least one polyisocyanate component and an active hydrogen component, wherein active hydrogen compounds of relatively high equivalent weight have an average of about 1.5 to about 4 active hydrogen-containing groups per molecule, of which active hydrogen-containing groups: an average of (a) from about 5 to about 60 percent are primary aliphatic amine groups or (b) at least about 25 percent are primary aromatic, secondary aliphatic, Lewis acid-blocked primary or secondary aliphatic or aromatic amine groups or mixtures of such groups. An amount of at least one alkali metal halide salt effective to increase load bearing strength of the foam is incorporated into the reaction mixture. Differing amounts of alkali metal halide salts are suitably incorporated into different areas of the foam to produce areas having differing load bearing strengths. The invention includes the foams formed by the processes of the invention as well as active hydrogen compositions containing the alkali metal halide salts and useful in the processes.
    • 本发明包括通过使包含至少一种多异氰酸酯组分和活性氢组分的反应混合物反应来制备柔性水喷雾聚脲泡沫的方法,其中相当高当量重量的活性氢化合物的平均值为约1.5至约4 活性含氢基团:其中活性含氢基团的平均(a)约5至约60%是伯脂族胺基团,或(b)至少约25%为伯芳族,仲脂肪族, 路易斯酸封闭的伯或仲脂族或芳族胺基或这些基团的混合物。 一定量的至少一种有效增加泡沫承载强度的碱金属卤化物盐被加入到反应混合物中。 不同量的碱金属卤化物盐适当地掺入到泡沫的不同区域中以产生具有不同承载强度的区域。 本发明包括通过本发明方法形成的泡沫以及含有碱金属卤化物盐的活性氢组合物并且可用于该方法。
