摘要
利用二苯基二甲氧基硅烷和苯基三甲氧基硅烷合成了聚硼硅氧烷树脂,并探索了最佳的合成工艺条件。将聚硼硅氧烷树脂添加到低密度聚乙烯/乙烯-醋酸乙烯酯共聚物/膨胀型阻燃剂(PE-LD/EVA/IFR)复合材料中,以期可以提高膨胀型阻燃剂与聚合物基体的相容性。采用氧指数仪、热重分析仪、力学性能测试等表征手段分析了复合材料的阻燃性能、热性能和力学性能。结果表明,聚硼硅氧烷树脂可提高复合材料的阻燃效果,并且对复合材料的力学性能没有明显的影响。
Polyborosiloxane resin was synthesized from diphenyldimethoxysilane and phenyltrimethoxysilane through hydrolysis and condensation, and then was blended with low density polyethylene/ethylene vinyl acetate coplymer/intumescent flame retardants (PE-LD/EVA/ IFR) composites to improve the compatibility between IFR and polymer. The flammability and the thermal behavior of the composites were investigated using limiting oxygen index and thermogravimetric analysis. It showed that a better flame retardancy was achieved by the addition of the polyborosiloxane resin with minimal negative effects in the mechanical properties.
