Study of reaction to fire in hybrid based core insulators intended for the of vacuum insulation panels

Popis výsledku v původním jazyce

The core insulators of vacuum insulation panels are mostly made from inorganic raw materials with a high SiO2 content, either in the form of nanoparticles or microfibers, while the proportion of organics is usually up to 3 %. The contribution is devoted to the study of reaction to fire in hybrid insulation materials made from a combination of nano SiO2-based particulate raw materials and organic-based fibrous raw materials, where the total proportion of organics is significantly greater than 3 %. Considering that it is a mixture of inorganic nanoparticles and organic microfibers with a total higher bulk density, the resulting behavior of these insulators in the field of reaction to fire is different from classic insulators (both fibrous and particulate). In the case of hybrid core insulators, which are the subject of the published study, the organic fibers are obtained by recycling old paper (municipal waste) and substitute part of the nano SiO2 in the core insulator. In this way, it is possible to significantly improve the environmental parameters of vacuum insulation panels with minimal deterioration of functional properties and durability. The paper describes how the substitution of SiO2 with organic microfibers will affect the key fire properties, especially the reaction to fire.
