摘要

利用含二氧化硅的工业原料开发了用作隔热材料的复合发泡无机材料，其导热系数降低到 0.064 - 0.076 W/(m - K)。研究了成孔剂和固化剂对发泡材料的结构、相形成和物理技术性能的影响。研究发现，石墨和白垩的结合使用会降低材料的密度，而石墨和石膏以及石墨和氟硅酸钠的结合使用则会提高材料的强度。

Foamed Inorganic Materials Based on Mineral Silica-Containing Raw Materials for Use as Thermal Insulation

Composite foamed inorganic materials for use as thermal insulation with a reduced thermal conductivity of 0.064 – 0.076 W/(m · K) were developed using industrial silica-containing raw materials. The influence of poreformers and hardeners on the structure, phase formation, and physico-technical properties of foamed materials was studied. It was observed that the combined use of graphite and chalk resulted in a reduction in the density of the materials, while the use of graphite and gypsum and graphite and sodium fluorosilicate led to an increase in the strength of the materials.
