摘要

以十八烷基二羟乙基甲基溴化铵(OMDAB)作为聚丙烯(PP)用抗静电剂。研究了OMDAB的吸水性、热稳定性

对PP的抗静电性的影响。利用XRD和DSC分析了OMDAB对PP结晶行为的影响。采用TG研究了OMDAB对PP热稳定性的影响。结果表明

多羟基的引入

使OMDAB的吸水性明显高于目前常用的抗静电剂SN。OMDAB添加量为PP的0.3%时抗静电效果最好

其抗静电耐久性、耐擦洗性优良。环境相对湿度每增加10%或环境温度由10℃升高至30℃时

PP制品表面电阻率均下降了约1个数量级。OMDAB的加入没有改变PP的晶型

但降低了PP的结晶速率及热稳定性。

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 1.05×1011Ω 7 d 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.
