The blending method, blending time, the level of waste rubber powder and WRP modified by resorcin and hexamethylenamine were investigated to find their influence on the mechanical properties of NR blends.

研究了共混方法、共混时间、废胶粉的用量以及废胶粉经间苯二酚和六次甲基四胺改性后对废胶粉/NR共混胶力学性能的影响。

NBR/modified montmorillonite and NR/HMMT nanocomposites were prepared by the mixing intercalation method with the monomers resorcin and hexamethylenetetramine complex . XRD and TEM showed that the interlayer spacing of HMMT had got much larger with RH addition and the layers of HMMT had dispersed in rubber matrix on nanometers. FTIR and crosslinking density results explained that chemical reaction had occurred between RH and rubber in the course of vulcanization, which improved the crosslinking density of rubber and enhanced the interaction between the rubber and HMMT.

采用单体混炼插层法，引入间苯二酚-六次甲基四胺的络合物，制备了橡胶／改性蒙脱土插层纳米复合材料。X-射线衍射分析表明：RH的加入使蒙脱土层间距不断扩大；TEM观察到无机片层在橡胶基体中纳米级分散；FTIR和交联密度的分析发现，在硫化过程中RH与橡胶发生化学键合反应，同时与改性蒙脱土相互作用，使得体系交联密度提高。

A study was made of the properties of NR and the effect that natural rubber latex was conserved with feeble-acid-ammonium salt.

通过对弱酸铵盐性质的分析，探索弱酸铵盐对鲜天然胶乳的保存效果及其性能的影响。
