Influence of Waterproofing Agent on Foamed Thermal Insulation Materials and its Mechanism Inquiry

Abstract:

Lightweight aggregates glazed hollow bead, cement, foaming agent, foam stabilizer and waterproofing agents as the main raw material, produce foamed thermal insulation materials by vibration shaping. By adding emulsified stearic acid and methyl stearate alcohol organosilicon waterproofing agent, the effects of two types of waterproofing agent on quality of water absorption of foamed thermal insulation materials were studied, and the related mechanisms were discussed. Results show that the waterproofing effect of organosilicon waterproofing agents is superior to emulsified stearic acid, when the content of emulsified stearic acid and organosilicon waterproofing agent are 7% and 4% respectively, 2h,24h water absorption rate of samples are 18.34%, 45.45% and 14.45%, 32.83%.
