研究癸酸钴和硼酰化钴以及粘合增进剂CS-964和Si69对胎体钢丝帘布胶粘合性能的影响。结果表明,癸酸钴较硼酰化钴能够提供给胶料更高的老化后粘合力保持率,同时胶料的耐疲劳性能较好;粘合增进剂CS-964可提高胶料定伸应力和耐疲劳性能,但用量过大会导致胶料老化后粘合力保持率下降;Si69有助于提高添加白炭黑的胎体钢丝帘布胶的物理性能,同时能改善胶料的耐疲劳性能。 相似文献

研究停放温度和停放时间对带束层胶和胎面胶性能的影响。结果表明:随着停放时间的延长,带束层胶和胎面胶的门尼粘度增大,且环境温度越高,增大趋势越明显,门尼焦烧时间缩短,且在较高温环境下,门尼焦烧时间更短;停放时间和停放温度对带束层胶的物理性能几乎没有影响,对胎面胶的定伸应力影响不大,但胎面胶的拉伸强度和拉断伸长率随着停放时间的延长而减小。 相似文献

An inclusion compound of Mo(VI,V,IV) complexes and poly(vinyl alcohol) (PVA) that contains some carbonyl groups was prepared by a photoelectron transfer reaction between PVA and 12-molybdophosphoric acid (PMo12). A dark-blue film was obtained when the aqueous solution of PMo12 and PVA was irradiated with UV light. The film exhibited the characteristic electron spin resonance (ESR) signal of Mo(V). The existence of Mo(VI,V,IV) complexes was supported by XPS analysis of the film. Furthermore, the infrared (IR) and ultraviolet–visible (UV–Vis) spectra of the film showed weak absorption bands at 1710 cm–1 and 300–314 nm that are consistent with carbonyl groups, which presumably are a result of partial oxidation of secondary hydroxyl groups on PVA. Differential scanning calorimetry (DSC) of the dark-blue film exhibited a peak at 220.3°C that is different from PMo12 and PVA. Except for the IR absorption at 1710 cm–1, the wavelengths and shapes of the other IR bands were similar to those of PVA. The UV–Vis spectrum of the film showed a new absorption band at 742–770 nm. In addition, the XRD spectrum of the film, the diffraction angles, and the crystalline sites were different from that in PMo12 or PVA. However, the peak shape was similar to that of PVA. In summary, the DSC, IR, UV–Vis, and XRD data support a Mo(VI,V,IV) complex that is included into the spiral tube structure of PVA, which contains some carbonyl groups. 相似文献

以肉豆蔻酸异丙酯(IPM)、癸甲溴铵(双十烷基二甲基溴化铵)、1,2-丙二醇和邻苯二甲醛为原料,制备了邻苯二甲醛纳米乳。用透射电镜(TEM)、激光粒度测定仪对其微观形貌进行了表征;通过恒温加速实验考察了其稳定性。结果表明:制备邻苯二甲醛纳米乳的最佳配比为:m(癸甲溴铵)∶m(1,2-丙二醇)=4∶1、m(癸甲溴铵+1,2-丙二醇)∶m(IPM)=9∶1、w(EDTA)=0.05%~1%、w(邻苯二甲醛)=10%;纳米乳在透射电镜下呈球形,粒径分布均匀,平均粒径48.2 nm;恒温加速实验显示其质量稳定,能提高邻苯二甲醛的溶解度,可望用于消毒领域。 相似文献
