| 研究不同并用比羧基丁腈胶乳（XNBRL）/羧基丁苯胶乳（XSBRL）并用胶膜的性能以及考察并用胶乳的相容性。结果表明：XNBRL/XSBRL的并用比为90/10时，XNBRL/XSBRL并用胶膜的t90最短，并用硫化胶膜的交联密度较大、拉伸强度最大（33.8 MPa）以及溶胀指数最小（2.10）；XNBRL/XSBRL并用胶乳的粘度略大于XNBRL；随着XSBRL用量的增大，XNBRL/XSBRL并用胶乳的机械稳定性变差，但变化幅度不大；XNBRL硫化胶膜和XNBRL/XSBRL并用硫化胶膜均仅有1个玻璃化温度，即XNBRL与XSBRL相容性很好，且XNBRL/XSBRL并用胶乳为均相体系；XNBRL/XSBRL并用硫化胶膜的XNBRL相与XSBRL相之间发生了化学键合，产生了共交联。 |
| 英文摘要: |
| The properties of carboxylated nitrile butadiene latex（XNBRL）/carboxylated styrene-butadiene latex（XSBRL） blend films with different blending ratios were studied and the compatibility of the blend latexes was investigated.The results showed that，when the blending ratio of XNBRL/XSBRL was 90/10，the t90 of XNBRL/XSBRL blend film was the shortest，the crosslinking density of the blend vulcanized film was higher，the tensile strength was the largest（33.8 MPa），and the swelling index was the smallest（2.10）.The viscosity of XNBRL/XSBRL blend latex was slightly larger than that of XNBRL.With the increase of the amount of XSBRL，the mechanical stability of XNBRL/XSBRL blend latex was becoming worse，but the change was not large.Both XNBRL vulcanized film and XNBRL/XSBRL blend vulcanized film had only one glass transition temperature， and XNBRL/XSBRL blend latex was a homogeneous system，indicating that XNBRL and XSBRL had good compatibility.The XNBRL phase and XSBRL phase of XNBRL/XSBRL blend vulcanized film were connected through chemical bonds，resulting in a co-crosslinked structure. |
