Abstract:
    The present invention relates to preparation process of hybridized epoxy resin/silica material. The preparation process includes the following steps: 1. preparing silica sol through mixing organosilicon, ethanol and water in the molar ratio of 1 to 2-6 to 2-6 to form liquid mixture; dropping acid to regulate the pH value of the liquid mixture to 2-5; stirring for 2-10 hr and sealed ageing at room temperature for 1-15 days; and 2. compounding the silica sol with epoxy resin to obtain the hybridized epoxy resin/silica material. The present invention adopts aged inorganic silica sol, and has small silica phase size and no obvious interphase interface in the product.
