摘要
研究表面改性剂对纳米粘土/天然胶乳复合材料性能的影响。结果表明:烷基表面活性剂对纳米粘土改性后,天然胶乳硫化胶膜老化前后的拉伸强度均明显提高,十六烷基三甲基溴化铵(CTAB)的改性效果最好,当改性纳米粘土用量为2份时,天然胶乳硫化胶膜的拉伸强度最高;CTAB改性纳米粘土能提高天然配合胶乳的保存稳定性、粘度和机械稳定性,并提高天然胶乳硫化胶膜的物理性能和耐热老化性能,补强效果明显。
The effect of surface modifiers on the properties of nanoclay/natural latex composites was investigated.The results showed that the tensile strength of the vulcanized natural latex film before and after heat aging were significantly improved after the nanoclay was modified by alkyl surfactant.Cetyltrimethylammonium bromide(CTAB)had the best modification effect on nanoclay.When the amount of modified nanoclay was 2 phr,the tensile strength of vulcanized natural latex film was the highest.CTAB modified nanoclay could improve the storage stability,viscosity and mechanical stability of compounded natural latex,and raisen the physical properties and heat aging resistance of vulcanized natural latex film,showing good reinforcement effect.
