| 摘 要： | 以废弃的聚苯乙烯为原料制备聚苯乙烯磺酸钠(SPS),考察了SPS对水泥净浆性能的影响。结果表明:向水泥基体中加入微量(例如水泥质量的10-5%)的SPS,水泥净浆的吸水率和化学结合水量减小,抗压强度、抗折强度和冲击强度增大;随着SPS掺量的增大,水泥净浆的吸水率和化学结合水量进一步减小,抗压强度、抗折强度和冲击强度进一步提高;但SPS掺量超过水泥质量的10-3%后,水泥净浆的吸水率略有增大,抗压强度、抗折强度和冲击强度略有降低;SPS的相对分子质量和磺化度对水泥净浆的性能几乎没有影响。

| Abstract: | Poly(sodium styrenesulfonate)(SPS) is prepared from the waste polystyrene by sulfonation with sulfuric acid as sulfonation agent. The effect of SPS on the cement paste properties has been studied. The result shows that the addition of SPS into cement pastes can decrease their water absorption and chemically combine water content, and increase their compressive strength, bending strength and impact strength. The water absorption and chemically combined water content continually decrease, and the compressive strength, bending strength and impact strength continually increase as SPS content increases. But the water absorption slightly increase and the compressive strength, bending strength and impact strength slightly decrease when the SPS contents exceed 10 -3% of the cement mass. The molecular weight and sulfonation degree of SPS have little effect on the cement paste properties. |
