Abstract
Silane-crosslinked halogen-free flame-retardant poly (ethylene-octene) elastomer (POE) compounds were prepared through a two-step melt-compounding method using Mg(OH)2 and Al(OH)3 as flame retardants,and its grafting rate was investigated in terms of different silanes and initiators.Mechanical properties,hot elongation performance,thermal decomposition behaviors and flame-retardant properties of the compounds were investigated by using a universal testing machine,a hot elongation tester,a thermogravimeter and a limiting oxygen index instrument.The results indicated that the silane-crosslinked POE initiated by dicumyl peroxide achieved a higher cross-linking degree than that by benzoyl peroxide.The crosslinking feasibility of POE with silane-crosslinking agents is in the order of vinyl trimethoxysilane＞vinyl triethoxysilane＞ γ-methacryloxypropyltrimethoxysilane.The silane-crosslinked flame-retardant POE achieved a higher limiting oxygen index and better mechanical properties than uncrosslinked ones.Moreover,POE/Mg(OH)2 compound obtained a higher char yield than POE/Al (OH)3 ones.The silanecrosslinked flame-retardant POE also presented more residual mass than uncrosslinked ones.关键词
