摘　　要：将淀粉纳米晶作为天然胶乳的补强剂,研究其对天然胶乳的胶体性能及硫化胶膜的物机性能、耐水性和耐溶剂的影响。研究结果表明:将淀粉纳米晶加入天然胶乳后,胶乳的粘度变化不大,机械稳定度提高;硫化胶膜的物机性能明显提高,耐溶剂性提高,而耐水性降低。Natural rubber latex （NRL） was reinforced by starch nanocrystal. The effects of starch nanocrystal on mechanical properties, solvent-resistance and water-resistance properties of vulcanized films and colloidal properties of the NRL were studied. The results showed that the viscosity of NRL had little change and mechanical stability of that improved. The mechanical properties and solvent-resistance of vulcanized films were enhanced, but the water-resistance was reduced.
