Изучение свойств теплоизоляционных материалов холодной поризации на основе жидкостекольного гранулята

Abstract

In recent decades, a growing interest in the possibility of replacing organic polymeric inorganic insulation foam that combine low thermal conductivity of heat resistance and incombustibility. In this paper we investigate the properties of thermal insulation materials made on the basis of swollen liquid glass granules and binder obtained by cold swelling by dint of different blowing agents. The binder consists of sodium liquid glass, filler, hardener, surface - active substance and a blowing agent. The choice of blowing agents. Was to find the optimal ratio of the granular thermal insulation material and liquid glass binder. Was investigated the effect of the amount and type of blowing agent in the physical and mechanical properties of the received swelling blocks: density, flexural strength, compressive strength, water absorption, hygroscopicity. The optimal content of different blowing agent in a communication system for thermal insulation materials.
