Thermal - insulation material for frame panels with an internal non-metallic layer

Abstract

The foam plastic capable to work in frame panels as a thermal - insulation and facing and decorative material can be only of composite type. We have developed a new type of composite foam plastic, its density increases from center to surfaces. The article presents the composition of new material, the technology of its production, as well as the mathematical model of the mechanism of formation of strong crusts at its surfaces. Microscopic analysis of the composite showed that the density of crust is more than 200 kg / m3, the density of the foam plastic in its middle part is 80 kg / m3. The limit of strength at punching it by the rod diameter 0.01 m reaches 3.5 MPa. The material is used for the manufacture of roofing panels, frame panels with an internal non-metallic layer.
