Abstract

For Russia, due to its long winter period, improvement of thermal insulation properties of envelope structures by applying thermal insulation paint and varnish coating to its inner surface is considered perspective. Thermal insulation properties of such coatings are provided by adding aluminosilicate microspheres and aluminum pigment to their composition. This study was focused on defining the effect of hollow aluminosilicate microspheres and aluminum pigment on the paint thermal insulation coating based on water-based polymer dispersion and on its optimum filling ratio. The optimum filling ratio was determined using the method of critical pigment volume concentration (CPVC). The optimum filling ratio was found equal to 55%.

Highlights

Heat transmission through building envelope structures can occur in different directions depending on climate conditions of the region
The main characteristics for paint coatings meant for interiors are water absorption of the film, opacity and adhesion to surface
It is known that critical pigment volume concentration (CPVC) of water-based styrene acrylic paints lies between 40 and 80% [22]

Summary

Introduction

Heat transmission through building envelope structures can occur in different directions depending on climate conditions of the region. The most relevant issue for countries with hot climate or long summer season is decrease of buildings heat gain caused by solar radiation This problem is solved by covering the surface of building envelope structures with coatings that can reflect solar radiati0n [1,2,3]. For Russia, due to its long winter period, improvement of thermal insulation properties of envelope structures by applying thermal insulation paint and varnish coating to its inner surface is considered perspective [4,5,6] Such materials represent viscous liquid compositions containing binder, hollow microspheres of various nature, such as polymers, glass, aluminosilicate, and titanium pigment [7,8,9,10,11,12]. The research is aimed to define the effect of hollow aluminosilicate microspheres and aluminum pigment on the paint thermal insulation coating based on water-based polymer dispersion and to find its optimum filling ratio
