Preparation and Study on the Properties of Expanded Perlite / Fly Ash Floating Beads Insulation Material

Abstract:

In this paper, expanded perlite / fly ash floating beads insulation material was made of expanded perlite, fly ash floating beads, cement, fly ash and VAE emulsion by adding decent additives, like waterproof agent, in the pressure forming process. The effects of molding pressure, VAE emulsion content, fly ash floating beads content and waterproofing agent content on the properties of thermal insulation material were studied, and the internal microscopic morphology of thermal insulation material was observed by SEM. Besides, the related action mechanism was explored. The test results show that the optimum ratio as follows: molding pressure of 0.46 MPa, VAE emulsion content of 20%, fly ash floating beads content of 20%, waterproof agent content of 7%.
