Preparation and Characterization of Nanoscale Silicate Composite Architectural Heat-Insulating Coatings

Abstract:

Article Preview

The architectural heat-insulating coatings were prepared by means of high speed mechanical agitation when the polymer emulsions were used as binder of the coatings and the mixed nanoscale silicate composites and nano-oxides were used in the presences of some assistants. Two types of nanoscale silicate composites architectural heat-insulating coatings were designedly produced out. The wide-angle X-ray powder diffraction patterns and the SEM images of the products show that the coating films are dense. The thermal conductivities of the heat-insulating coatings are in the ranges of 0.094487~0.148973 W/m•°C which are obviously smaller than the standard rubber sheet, for example, the thermal conductivity of the calcium silicate nanowires composite coating is nearly 0.094487 W/m•°C only. The nanoscale silicate composite architectural heat-insulating coatings are in good agreement with the parameters in the GBT 17371-2008 (Silicate composite insulation coating).
