【摘要】 为提高碳酸镁/氢氧化铝复配阻燃聚乙烯体系的性能,将有机硅和EVA添加到阻燃体系中,测量其氧指数、拉伸强度和断裂伸长率。实验表明:有机硅是该体系很好的阻燃协效剂,而用EVA改性基础树脂,不但可以提高体系的阻燃性能,还可以提高体系的断裂伸长率。更多还原

【Abstract】 To improve the property of Magnesium Carbonate and Aluminium Hydroxide compound with flame-retardant PE system,Organic silicon and EVA were added into the flame-retardant PE system.The Oxygen index,the tensile strength and the elongation at break were tested.The results indicate that organic silicon is the efficient synergistic agent for the flame-retardant system,and base resin modified by EVA has better flame-retardant performance,meanwhile the elongation at break of the system is improved too.更多还原
