【Abstract】 Using the different types of nano- SiO2,the unsaturated polyester( UP) /nano- SiO2 gel coat resin was prepared under the different technique of production and its action mechanism was analyzed. The result indicated the nano- SiO2 may improve of the mechanical properties of the compound materials,enhance the material longitudinal strength and the shock strength effectively. At the same time,nano- SiO2 also had the ultraviolet shielding effect and might have the ageing resistance. Using nano- SiO2 as the component of the unsaturated polyester enhancement,it can obtain the overall performance good gel coat resin.更多还原
