Abstract: The composite materials for self-operating temperature were prepared by sepiolite and dodecanol as materials. Then thermal insulation putty for exterior wall was prepared by the sepiolite composite materials as main functional additives and acrylic emulsion as adhesive. The main properties of the putty films were studied by thermal insulation effect testing device. The results show that the putty films could arrest heat transmission effectively.

Abstract: Thermal insulating latex paint for exterior wall was prepared by water as dispersing media, polyacrylic emulsion as basic material, defibered sepiolite and hollow glass microspheres as main functional additives. The thermal insulation effect and mechanism were studied by thermal insulation effect testing device and visible light reflectance tester. The results show that the optimum contents of functional additives are as follows: 8% defibred sepiolite fibers, 6% hollow glass microspheres. The coating could arrest heat transmission and reflect visible light effectively.
