Abstract

A sintered shale self-insulation hollow brick comprises following raw materials: shale, modified attapulgite, volcanic ash, coal gangue, cement, fly ash, straw, and water. The preparation method of modified attapulgite comprises following steps: dissolving 3-aminomethyl triethoxysilane and methyl triethoxysilane into an alcohol-water mixture, then adding grinded attapulgite, adjusting the pH, andstirring to obtain silane coupling agent modified attapulgite. The invention provides a sintered shale self-insulation hollow brick and a preparation technology thereof. A silane coupling agent is used to modify attapulgite so as to well organize the surface of attapulgite. The mechanical properties of the composite material are improved, the caking property is enhanced, compared with high viscosity attapulgite, attapulgite is easy to obtain, and the prepared hollow brick has a very good thermal insulation performance.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a sintered shale self-insulating hollow brick and a preparation process thereof. Background technique [0002] With the country's reform of building energy saving and new wall materials, sintered shale porous bricks have been recognized as a sustainable new wall material in my country due to their energy-saving and land-saving characteristics, and the rich output and wide distribution of shale. Promote. With the emergence of the energy crisis, especially the less and less non-renewable resources, the significance of energy conservation in the national economy has become more and more important, and the government has paid more and more attention to the reuse of energy and energy conservation. Wall materials are the basic industry in the field of building energy conservation. Scholars at home and abroad have conducted a large number of experimental studies on the ther...
