Abstract

The invention belongs to the technical field of novel materials and in particular provides porous glass ceramics, mainly nano-pore glass ceramics prepared with pegmatite as a raw material. The nano-pore glass ceramics are prepared by adopting the method of adding a pore forming agent stearic acid and a binder polyvinyl alcohol and carrying out second sintering. The nano-pore glass ceramics also take silica, calcite, borax, zinc oxide, sodium nitrate and sodium carbonate as additives. Compared with common heat insulating materials, the nano-pore glass ceramics have the advantages of high compressive and flexural strength, heat shock resistance, low heat capacities and good heat insulating properties, are the best materials for external wall insulation, are low in preparation costs and are suitable for popularization and application in related technical fields.

Description

technical field [0001] The invention belongs to the technical field of new materials, in particular to a porous glass-ceramic made of pegmatite as a raw material. Background technique [0002] my country is very rich in non-metallic mineral resources, such as quartz ore, quartz sand, boron ore, kaolin, limestone, dolomite, wollastonite, pegmatite, etc. Some minerals have been used efficiently, especially in the field of building materials. Wide range of applications. People often attach importance to the manufacture of steel bars, concrete, cement, bricks and other materials, because these materials are commonly used materials and are related to the safety of human life. However, insufficient attention has been paid to thermal insulation materials and their correct and reasonable application. In construction engineering, after the promulgation of JGJ26-86 and JGJ26-95 of the "Civil Building Energy Efficiency Design Standards", all aspects are vigorously promoting and popula...
