Preparation of POSS-triol/wollastonite composite particles by Liquid phase mechanochemical method and its application in UV curable coatings
Source abstract
Abstract
Abstract POSS-coated wollastonite composite particles were prepared by the liquid phase mechano-chemical grinding of wollastonite and POSS powder together in the high pressure homogenizer [1, 2, 3, 4] for the first time. And then we prepare UV curable coatings of vinyl trimethoxy silane(VTMS) / butyl acrylate (BA) with different content of composite particles [5]. Nuclear magnetic resonance spectroscopy, scanning electron microscopy and infrared spectra were used to investigate the microstructures and morphologies of the composite. The properties of the coatings are tested by FTIR, SEM, water contact angles and so on. The results indicate that the POSS was successfully loaded on the surface of silica fume to prepare composite particles and when the addition of the composite particles is 12%, the water contact angle of the UV curable coating reaches 151.96 ∘ , and the mechanical properties of the coating are also qualified.
