【摘要】	<正>可膨胀石墨(EG)在高温下受热可迅速膨胀,膨胀倍数高达数十倍到数百倍,因而,作为典型的物理膨胀阻燃剂,其研究和应用成为阻燃领域研究的热点[1～4]。
【英文摘要】	Expandable graphite intercalated by ammonium phosphate (AP) or ammonium polyphosphate (APP) was prepared by direct intercalation and two-step method, respectively. The products from two-step method show higher expansion volume, more weight increase and more weight loss after expansion, suggesting that the two-step method is a favorable method for preparation of APP intercalated EG. XRD provides convincing evidence for successful formation of APP-EG by showing strong diffraction peak at much lower 2θ angle. ...
