十八烷基二羟乙基甲基溴化铵作为聚丙烯抗静电添加剂的研究
Research of octadecyl methyl dihydroxyethyl ammonium bromide as antistatic agent in polypropylene
摘要
Abstract
Octadecyl methyl dihydroxyethyl ammonium bromide (OMDAB) was used in polypropylene (PP) as antistatic agent. The moisture absorption and thermal stability of OMDAB were investigated. The influence of OMDAB on antistatic property of PP was studied. Crystallization behavior was explored by X-ray diffraction (XRD) and differential scanning calorimetry (DSC). The thermal property of PP was studied by thermogravimetric analysis (TG). The test results showed that the moisture absorption of OMDAB was greater than the commonly used antistatic agent SN because of multi-hydroxyl group. After adding 0. 3% (mass) of OMDAB into PP surface resistivity of the blend decreased to 1. 05×1011Ω7d later. The blend had good antistatic durability and launderability. When humidity increased by every 10% or ambient temperature increased from 10℃ to 30℃ , surface resistivity of the blend decreased by one order of magnitude. OMDAB did not change crystal structure of PP but reduced the rate of crystallization. Thermal stability of PP was weakened by OMDAB.关键词
