摘　　要：以经过改性废旧EPS(聚苯乙烯)颗粒为保温骨料,以石膏-矿渣胶凝材料为无机粘结材料,制备出具有一定的强度、造价低廉、利废节能且具有良好保温性能的EPS-石膏-矿渣墙体保温材料,并研究了聚苯乙烯颗粒含量与该复合材料各项性能的关系。结果表明,对EPS颗粒进行改性处理,其作用效果明显,能显著改善EPS-石膏-矿渣墙体保温材料的各项性能,提高材料的强度和软化系数;随着EPS颗粒含量的增加,材料的强度迅速降低,密度下降,导热系数随之减小,而软化系数略有提高。Through the modification of waste EPS particles as thermal insulation aggregate, with gypsum and slag cementitious materials for inorganic materials, preparation of a certain strength, low cost, waste energy and has good heat preservation performance of EPS-gypsum and slag wall insulation materials, and the study of polystyrene particle content and the composite material the performance relationship. The results show that, the EPS particles are modified, the effect is apparent, can significantly improve EPS gypsum slag wall insulation material properties, improve the material strength and softening coefficient; with EPS content increasing, the strength of the material decreases rapidly, density, thermal conductivity coefficient decreases, whereas the softening coefficient slightly improve.
