    • A method for preparing phenolic resin nanocomposites and epoxy resin nanocomposites is provided to inhibit layered silicate from directly reacting to epoxy resin, thereby improving storage stability. A method for preparing epoxy resin nanocomposites comprises the following steps of: preparing embedment type phenolic resin nanocomposite from organized layered silicate and phenolic resin; and mixing the embedment type phenolic resin nanocomposite and epoxy resin to prepare uncured or semi-cured epoxy resin nanocomposites. In the mixing step of phenolic resin nanocomposite and epoxy resin, 0.5-1.5 equivalent of epoxy group is mixed to 1 equivalent of hydroxyl group of the phenolic resin included in the phenolic resin nanocomposite. The method for mixing the phenolic resin nanocomposite and epoxy resin consists of stirring the mixture at 60-200°C for 1 minute~5 hours.
    • 提供了制备酚醛树脂纳米复合材料和环氧树脂纳米复合材料的方法,以抑制层状硅酸盐与环氧树脂直接反应,从而提高储存稳定性。 一种制备环氧树脂纳米复合材料的方法,包括以下步骤:由有组织的层状硅酸盐和酚醛树脂制备嵌入型酚醛树脂纳米复合材料; 并将嵌入式酚醛树脂纳米复合材料和环氧树脂混合,制备未固化或半固化的环氧树脂纳米复合材料。 在酚醛树脂纳米复合材料和环氧树脂的混合步骤中,将0.5-1.5当量的环氧基与酚醛树脂纳米复合材料中包含的酚醛树脂的1当量羟基混合。 酚醛树脂纳米复合材料和环氧树脂的混合方法是将混合物在60-200℃下搅拌1分钟〜5小时。
