摘要
以低聚物多元醇(PTMEG)、甲苯二异氰酸酯(TDI 100)、扩链剂(MOCA)和无机粒子(13X型分子筛,SiO2)为原料,采用预聚法合成出聚氨酯(PU)/分子筛及PU/SiO2复合材料,并对其力学性能进行了测试。结果表明:聚氨酯/分子筛复合材料比纯聚氨酯具有更优良的力学性能,分子筛的加入量为3%～7%(质量分数),扩链系数为0.90～0.95时,其拉伸强度和耐撕裂强度均有明显提高;与PU/SiO2复合材料相比,PU/分子筛复合材料的力学性能和工艺性能更优。
The novel polyurethane/zeolites 13X composites were made with zeolites (13X), PTMEG, MOCA and polyisocyanated(TDI-100) as the raw materials by prepolymer process. The results show that PU/zeolite composites have good dynamic properties. Compared with those of pure PU, the tensile strenth and tear strenth of PU/13X composites increased from 43.1 MPa to 54.0 MPa and from 71.6 kN/m to 96.4 kN/m, respectively. PU/zeolite composites displayed better dynamic properties than PU/SiO2 composites with fillers contented.
