FLAME-RETARDANT SYNTHETIC RESIN COMPOSITION CONTAINING DELAMINATED LAYERED DOUBLE HYDROXIDE

摘要

PROBLEM TO BE SOLVED: To provide a flame-retardant synthetic resin composition containing flame-retarding layered double hydroxide dispersed in a matrix resin in a delaminated state.;SOLUTION: The flame-retardant synthetic resin composition contains a flame-retarding effective amount of a layered double hydroxide comprising a basic layer composed of a metal double hydroxide expressed by formula (I): M(II)_1-xM(III)_x(OH)₂ (M(II) is Mg, Zn or their mixture; M(III) is Al; and x is 0.2-0.33), an acetic acid salt of Mg, Zn or Ce intercalated in the intermediate layer of the basic layer and interlaminar water and is reversibly delaminated in water. The synthetic resin is a polycondensation resin containing a raw material releasing the layered double hydroxide in the production process of the resin, and the layered double hydroxide is uniformly dispersed in the synthetic resin in delaminated state by adding the double hydroxide to the raw material during the production process of the synthetic resin.;COPYRIGHT: (C)2008,JPO&INPIT
