Abstract

Abstract

Using styrene acrylic emulsion, slag geopolymer and graphite powders as raw materials, a foam composite material with the characterstics of self-leveling, fast film-foeming and soildification, high elasticity, and high heat transfer was prepared by the principle of chemical foaming. This paper studied the influence of the content of hydrogen peroxide, the content of thermally conductive graphite powder and its particle size distribution on the heat transfer performance, material mechanical properties and compression deformation properties of foam composites. The research results show that with the increase of the amount of hydrogen peroxide, the tensile strength, elongation at break, compressive strength and thermal conductivity of the foam composite material decrease, and the elastic recovery rate increases; as the content of thermally conductive graphite powder increasing, the tensile strength first increases and then decreases, the elongation at break decreases, the conpressive strength increases, the elastic recovery rate fluctuates slightly, and thermal conductivity increases. As the average particle size of the thermally conductive graphite powder increasing, the tensile strength decreases and the compressive strength increases, and the thermal conductivity first increases and then drcreases. The particle composition of thermally conductive graphite powder has an important effect on its thermal conductivity. Compared with coares and fine particles, a moderate particle gradation can make it form a more effective heat conduction network to obtain a higher thermal conductivity.
