摘要

Tri(1-chloro-3-etoxy-propane-2-ol) borate (I) was obtained by reaction of tri(hydroxyethyl)borate and epichlorohydrin.Reaction product was applied as fire retardant forpreparation of rigid polyuethane-polyisocyanurate foams.As the (I) content was increased from 0.1 to 0.4 of the chemical equivalent,the compressive strength,oxygenindex,residue after combustion and content of closed cells rose but brittleness,softening point and water absorption decreased.however,(I) presence does not influence explicitly on the foam apparent density.The results of our studies showed that chloroboroorganic compound [ChBOC,(I)] is generally useful as an additive to improve the properties of rigid PUR-PIR foams.
