Using graft polymerization of fumed silica surface modification using polymer macromolecular chains to effectively block the nanoparticle silica products, reduce their agglomeration and then filled with polypropylene, using the blending process for the preparation of integrated high performance fumed nano Si02 / PP composites. At low amount of the silica, can improve the toughness of polypropylene about twice. At the same time, if the composite system by adding an appropriate amount of elastomer, polypropylene is in keeping rigidity and tensile strength, ability to make anti-notched impact polypropylene increased by about three times, analysts believe that the fumed silica and the elastomer can be synergistic, the purpose of toughening polypropylene. The added advantage of blending fumed silica nano PMMA prepared Si02 / PMMA plastics, can significantly improve the performance of the material. When you add the amount of 4%, the notched impact strength of PMMA can increase more than 80% silica companies, and a composite material having a good optical transparency. Almost all the features Si02 applications thixotropic polyester resin and gelcoat in thixotropic polyester resin, fumed silica is used, on the one hand it can make the products more uniform thickness, shrinkage, more in line with design requirements; the other hand, the highest sales of silicon dioxide, the resin having a thixotropic resin flow and reduce r dripping, reducing waste resin. Protected. Production environment. In the styrene content of 43.5% phthalic unsaturated polyester, 2% of fumed silica to achieve a thixotropic index of 4.8, the thixotropic index has to meet domestic gelcoat construction technology. The provisions of the State Bureau of Technical Supervision, hand lay-up glass fiber reinforced gel coat and resin-rich layer of unsaturated polyester resins used in food containers, except for use of fumed silica thixotropic agent shall not join other inorganic fillers.
