Flame Retarding Performance of Polypropylene
Abstract:this paper first examines the expansion type flame retardant (IFR) such as: ammonium polyphosphate, pentaerythritol,and magnesium hydroxide flame retardant properties of polypropylene (PP).Results show that each single component of polypropylene prepared homemade materials even if the content reached 30%, oxygen index of the highest group was 23.8, but the tensile strength of only 7.55.Added to improve the flame retardant properties of fire retardant polypropylene material, the paper further discusses the three kinds of flame retardant additives binary compound system of the flame retardant properties of PP material.Research results show that the APP/PER/PP flame retardant material has synergistic effect of high oxygen index, at 35.8, but the same material tensile strength dropped sharply, to 10.92MPa.Finally thesis research including APP/PER/Mg(OH)2 ternary composite flame retardant properties of PP material adding system,and the ratio of additive was optimized,when the additive proportion of APP/PER/Mg(OH)2 ratio of 1:2:1, materials for oxygen index was 23.9, the tensile strength of 20.48MPa, good flame retardant performance, and mechanical performance meet the requirements.
