Abstract

<p>The mechanochemical polymerization method uses active center of the powder fracture surface to produce by grinding operation, and it is method to approximately completely carry out a polymer coating in crushed inorganic surface. We focused the attention on the waste glass of the car which had low recycling percentage achievement, and we thought about reusing this as silica filler by mechanochemical polymerization processing now. We found what a polymer generated in the water recently by carrying out mechanochemical polymerization reaction with the high ability mill for grinding such as the planetary mill. Therefore, a preparation of the polymer coating silica filler by the wet grinding using the water was investigated. As a result, we succeeded in a preparation of the silica filler that surface of the waste glass was coated with a polymer. Hence progress of the mechanochemical polymerization reaction was confirmed by grinding of the waste glass in the water. In addition, the particle diameter of the product was around 200 nm without depending on the particle diameter of raw materials.</p>
