Development of heat insulating coatings comprising ash microspheres

Abstract

The paper considers the production of heat-insulating paints using ash microspheres as a microfiller. It is shown how the technology factors change the properties of paintwork materials based on Latex DL 424 water-dispersion acrylic latex and 0.071–0.14 mm ash micro-spheres with the bulk density of 371 kg/m3. The optimum composition of paintwork materials is determined with regard of the coating production of the required quality. The experiments result in the increase in the coating strength and hardness due to the intensive polymerization of styrene-acrylic latex in ash microspheres. It is found that the obtained samples also possess high adhesion to ceramic and metal substrates, high corrosion resistance and low thermal conductivity. In addition, the use of the polymer binder in the composition makes allows increasing the coating elasticity and, as a consequence, the resistance to washing and abrasion. The obtained heat-insulating material can be used for various surfaces of walls, ceilings, roofs of buildings and structures, pipelines, boilers, and many others.
