摘要
Abstract
Irradiation-crosslinked polyolefin composites were prepared by ethylene-vinyl acetate copolymer with intumescent flame retardant (IFR)of modified pentaerythritol as char-forming agent through melt blending,and their flame retardant performance,electrical properties and thermal stability were investigated by limiting oxygen index,high resistance meter,breakdown tester and thermogravimetic analysis.The results indicated that,when 40 wt % of the complex flame retardants was introduced and the irradiation dose was less than 90 kGy,the resulting EVA/IFR-MPER systems achieved an improvement in flame retardancy by 1.5 %.Furthermore,their breakdown field strength,volume resistivity,maximum decomposition temperature and carbon yield at 600 ℃ increased by 2.2 MV/m,0.6 × 1013 Ω · m,4.43 ℃ and 8.52 %,respectively.关键词
