The thermal and mechanical properties of high density polyethylene (HDPE) and fumed nano-silica were studied. The results show that the thermal decomposition property and dimensional stability of the composite filled with modified nano-silica are improved. When the filling mass fraction of nano-silica is 2%, the fracture stress of polyethylene material is significantly increased. Polyvinyl chloride is a universal plastic, and the addition of silica nanoparticles to polyvinyl chloride strengthens and toughens the composite. The nano-silica particles were modified with γ-methylacryloxypropyl trimethoxysilane respectively, and then fused and mixed with PVC to prepare PVC composites. It is found that the modified nano-silica can strengthen and toughen the PVC composite
 

Nano silica is an amorphous white powder, non-toxic, tasteless, non-pollution, generally there are hydroxyl groups and adsorbed water on the surface, with small particle size, high purity, low density, large specific surface area, good dispersion performance, as well as superior stability, strengthening, thixotropy and excellent optical and mechanical properties. Widely used in ceramics, rubber, plastic, paint, pigment and catalyst carrier and other fields, it is of great significance to upgrade some traditional products. Nano-silica can also be used as filler reinforcers in coatings, cosmetics, rubber, and plastics. In addition, it has been used in biology and medicine in recent years.
