蒸压膨胀珍珠岩保温板的研制及性能分析

Research on the preparation and properties of autoclaved insulation board made by expanded perlite

采用2种堆积密度不同的膨胀珍珠岩作轻骨料,以水泥和自制胶结料作为胶凝材料,通过蒸压养护方式制备成保温板,并进行了憎水处理。结果表明,采用该工艺制备的保温板其抗压及抗折强度优于GB/T 10303—2001《膨胀珍珠岩绝热制品》标准要求;有机硅憎水剂乳液可显著降低保温板的体积吸水率。

Expanded perlite insulation board was successfully prepared by autoclave curing method,which two kinds of expanded perlite with different packing densities were used as fight-weight aggregate respectively, and Portland cement or self-made hinder was used as cementing material. Hydrophobic treatment was also applied. The results indicate that the compressive and flexural strengths of insulation board made in this way are much higher than the requirement in national standard GB/T 10303-2001 ＂Expanded Perlite Thermal Insulation＂; volume water absorption of EP insulation board is reduced significantly when the emulsion of silicone hydrophobic agent is used.
