ABSTRACT Two phosphorus‐containing silane coupling agents (PSCAs), KH550‐P and KH560‐P, are successfully prepared by reacting 10‐hydroxy‐9,10‐dihydro‐9‐oxa‐10‐phosphorus‐10‐oxide (DOPOOH) with (3‐aminopropyl) triethoxysilane (KH550) 3‐glycidyloxypropyltrimethoxysilane (KH560), respectively. These two PSCAs used as the surface modification of ammonium polyphosphate (APP). The flame retardancy mechanical properties epoxy resin (EP) PSCA‐modified APP investigated. When weight ratio to is 18:2 addition amount APPs, APP‐KH550‐P APP‐KH560‐P , in EP reaches 8%, resulting flame‐retardant composite materials, EP/APP‐KH550‐P EP/APP‐KH560‐P exhibit good a V‐0 rating vertical combustion test (UL‐94). limiting oxygen index values both higher than 30%. peak heat release rates decrease 13.8% 28.5%, respectively, compared containing 8% (EP/APP). Both KH560‐P demonstrate similar performance enhancing APP. added EP, found be those EP/APP. Conversely, tensile strength impact increase 23.8% 74.3%, shows significantly better EP.
