    • Disclosed is a method of preparing a bio-based thermosetting foam material with improved properties, in particular improved flame retardant properties, which method includes the steps of a) producing a prepolymer by condensation of at least one phenolic compound and formaldehyde in a ratio of 1:1.0 to 3.0 using 0.15 to 5 wt % of an alkaline catalyst in the temperature range of 50 to 100° C. until the refractive index of the reaction mixture is 1.4990 to 1.5020, b) adding 2 to 40 wt % of at least one natural polyphenol at a temperature of 50 to 100° C., c) adding 2 to 10 wt % of one or more emulsifiers and mixtures thereof, d) adding 2 to 10 wt % of one or more foaming agents and mixtures thereof and e) adding 10 to 20 wt % of a curing agent and f) curing. All wt % being related to the amount of the raw materials used.
    • 公开了一种制备具有改进的性能,特别是改进的阻燃性能的生物基热固性泡沫材料的方法,该方法包括以下步骤:a)通过至少一种酚类化合物和甲醛以1的比例缩合制备预聚物 :在50〜100℃的温度范围内使用0.15〜5重量%的碱性催化剂,直到反应混合物的折射率为1.4990〜1.5020,b)加入2〜40重量%的至少1个 天然多酚,温度为50至100℃,c)加入2至10重量%的一种或多种乳化剂及其混合物,d)加入2至10重量%的一种或多种发泡剂及其混合物,和e) 加入固化剂10〜20重量%,f)固化。 所有wt%与所用原料的量有关。
