The paper presents some aspects of an experimental research in which basic recipes have been designed in order to obtain innovative products to be used in construction as finishing coatings. Starting from sunflower seed shells, considered a waste rather a by-product resulting from the industry of edible sunflower oil, and also from rough sheep wool, an animal waste from the zootechnical field, and also from the specific thermal insulating characteristics of theese two waste materials, a serie of basic recipes was ...

The experimental research studied the possibility to develop an innovative coating type having a finishing and also a thermal isolating function, starting from three materials different as nature and presentation forms: kaolin powder ? a natural nanocompound, perlite granules ? a natural traditional thermal isolating material and an acrylic coating in aqueous dispersion with ceramic microspheres ? a modern synthetic thermal isolation nanoproduct. Three recipes of the new product type were made aiming to obtain hom...

Coatings based on microspheres are internationally recognized for their heat insulation characteristics, due to the specific properties of their nanoparticles ? ceramic, glass, silicon microspheres - even when the layer thickness has only 1-2 millimetres. Taking into account the high price of such products, the research studied, through specific experimental laboratory works, the possibility of obtaining a new and cheaper heat insulating product, by introducing kaolin as a filler. The experimental results showed n...
