摘要:
Polyurethane composites and methods of preparing polyurethane composites are described herein. The polyurethane composite can comprise (a) a polyurethane formed by the reaction of (i) one or more isocyanates selected from the group consisting of diisocyanates, polyisocyanates, and mixtures thereof, and (ii) one or more polyols; (b) fly ash comprising 50% or greater by weight, fly ash particles having a particle size of from 0.2 micron to 100 microns; and (c) a coarse filler material comprising 80% or greater by weight, filler particles having a particle size of from greater than 250 microns to 10 mm. The coarse filler material can be present in the composite in an amount of from 1% to 40% by weight, based on the total weight of the composite. The weight ratio of the fly ash to the coarse filler material can be from 9:1 to 200:1.
