In this paper, the high-efficiency degradation and alcoholysis recovery of waste polyurethane foam were realized using a combination alkali metal catalyst (CsOH) two-component mixed agents (glycerol butanediol) in different proportions, recycled polyether polyol one-step foaming to prepare regenerated thermosetting hard foam. The agent adjusted experimentally foam, series tests conducted on viscosity, GPC, hydroxyl value, infrared spectrum, time, apparent density, compressive strength, other...
Abstract Rigid polyurethane (PU) foam waste was chemically degraded by the two-component alcoholysis agent of diethylene glycol and ethanolamine graphine oxide (GO), PU/GO nanocomposites were obtained one-step foaming. PU adding different proportions GO. Research on introduction GO to degrade matrices, using degradation law oligomer polyols for regeneration, conducted through viscosity hydroxyl value recycled polyol determination, infrared spectrum samples, x-ray photoelectron spectroscopy,...
