Abstract
Methods of compounding nanoparticles (e.g., surface-modified silica nanoparticles) with a resin (e.g., a curable resin) are described. The methods use continuous wet milling technology and can be used to compound nanoparticles, including highly aggregated and agglomerated surface-modified nanoparticles, into a resin or resin precursor.
Claims17
A method of preparing a nanoparticle-containing resin system comprising mixing surface-modifed silica nanoparticles with a reactive monomer resin system to form a mixture, wherein the mixture comprises less than 5% by weight solvent and less than 1% by weight of a dispersant;
- and milling the mixture in a first continuous wet milling apparatus comprising milling beads to form a first milled resin system.
