Abstract

This work investigates the influence of kaolin and dolomite on the properties of polyurethane foam. The selected fillers were pulverized and sieved to obtained < 90 μm that were used as reinforcements in the polyurethane matrix in a randomly dispersed mode. The matrix constituents were mixed in the same ratio while fillers were introduced via a one-shot system approach in predetermined proportions of 3–7 wt.%. The work was carried out to identify optimum fillers to be utilized in the production of polyurethane rigid foams given the effect of the fillers on the physical, mechanical, and chemical properties of the foam. FTIR, XRF, and SEM and mechanical property tests were carried out on the filled polyurethane foam. The presence of the fillers in the foam showed a rupture in the structure of the foams with the cells having similar arrangements. The addition of dolomite and Kaolin degrades the sulfonic acid groups and promoted the appearance of Si–O stretching vibration band. The density, hardness, flexural and compressive strengths of the polyurethane foam were enhanced with the the addition of dolomite and kaolin particles.

高岭土和白云石对聚氨酯泡沫性能影响的对比研究

研究了高岭土和白云石对聚氨酯泡沫材料性能的影响。将所选择的填料粉碎、筛分，得到< 90 μm的填料，以随机分散的方式作为聚氨酯基体的增强材料。基体成分以相同的比例混合，而填料以预定比例3 - 7wt .%通过一次性系统方法引入。考虑到填料对泡沫的物理、机械和化学性能的影响，进行了这项工作，以确定用于生产聚氨酯硬质泡沫的最佳填料。对填充后的聚氨酯泡沫进行了FTIR、XRF、SEM和力学性能测试。泡沫中填充物的存在表明泡沫的结构破裂，细胞具有相似的排列。白云石和高岭土的加入降解了磺酸基团，促进了Si-O伸缩振动带的出现。白云石和高岭土颗粒的加入提高了聚氨酯泡沫的密度、硬度、抗折强度和抗压强度。
