Study on Preparation and Properties of PMMA Composite Microspheres as the Matrix of Low Density Proppant

In this paper, suspension polymerization is used for the preparation of PMMA microspheres, PMMA cross-linking DVB microspheres, PMMA-co-St composite microspheres and PMMA-St-SiO 2 composite microspheres, and apply IR spectroscopy, scanning electron microscopy, compressive strength, density, thermal analysis to the prepared polymer microspheres. The purpose of our work is to find the feasibility method of synthesis process for PMMA material and composite microspheres, and the prepared theoretical basis of proppant with low density and high strength for oil drilling applications by performance test.
