Abstract


In this thesis with resorcinol and phenyl phosphoric acid dichloride (PPD) and the first successful synthesis of a new phosphorus-containing compounds : 2 - phenoxy ( 3 - hydroxy ) phenyl phosphorus oxide ( BPHPPO ) , its the chemical structures were characterized using IR, MS , 1H NMR . Synthesis of the synthetic BPHPPO with epichlorohydrin plus base-catalyzed reaction of a new type of phosphorus - containing flame-retardant epoxy ( BPHPPO -EP ) , and the chemical structure of the bad epoxy resin BPHPPO-EP infrared, proton spectra characterized by improving hydrochloric acid - acetone measured BPHPPO-EP epoxy value of 0.442 . Thermogravimetric (TGA) of 4-4'- diamino - diphenyl sulfone (DDS) as a curing agent BPHPPO-EP cured epoxy resin heat- stability analysis, a residue in a nitrogen gas under the conditions of 800 ° C char yield up to 51.8%, the results show that , BPHPPO-EP/DDS cured product having excellent thermal stability , the thermal stability is better than the thermal stability of the the brominated epoxy TBBA-EP/DDS and BA-EP/DDS cured sex . Was measured by oxygen index (LOI) of the flame retardant properties, BPHPPO-EP/DDS measured obtaining an oxygen index of 34, a comparative test and the flame retardant properties of TBBA-EP/DDS the cured BA-EP/DDS cured show , BPHPPO-EP/DDS the flame retardant properties of the cured product is superior flame retardant properties of the cured product of TBBA-EP/DDS and BP-EP/DDS , and BPHPPO-EP/DDS cured in the combustion process has a low smoke emission performance . The results of this study can provide the basis for comprehensive performance of the phosphorus-containing flame retardant epoxy resin precursor development to BPHPPO is .
