Self- insulating energy-conserving building block for construction wall and method for producing the same

Abstract

The invention relates to a self heat preservation energy-saving building block used in the building wall and a production method thereof. The building block mainly utilizes waste concrete as raw material. The production method comprises the steps: the waste concrete is sorted out, crushed and treated by ball milling, and then is mixed with cement, lime, plaster, aluminium powder, methyl containing hydrogen silicone oil, additive and water to be prepared into sizing agent; the obtained sizing agent is processed by stirring, being blown off steam, precuring, cutting, pressurizing and curing, milling and repairing to form a recycled concrete autoclaved aerated concrete building block, and polyurea hard foam heat insulating material is poured between two concrete fixture blocks, so that the self heat preservation energy-saving building block is prepared. The invention has the remarkable advantages of changing waste into valuable, saving energy and resource and protecting the environment. When the self heat preservation energy-saving building blocks are built into the building wall, the advantages of heat preservation, energy conservation, safe use and the like can be fully developed.

Description

technical field [0001] The present invention relates to a building block in a building wall and a production method thereof. Background technique [0002] At present, with the continuous development of human civilization, the per capita consumption of concrete materials is increasing, and the environmental problems generated at the same time are becoming more and more significant. The cement concrete industry not only consumes a lot of energy and resources, but also emits a lot of CO 2 and NO seriously pollute the environment; on the other hand, due to the rapid development of the construction industry, construction waste piles up like mountains, and the environmental problems caused are also obvious; on the other hand, the current wall materials generally still use natural stone and sand, resulting in mountain destroyed, landslides and even river diversions occurred. Although exterior wall insulation technology can significantly save building energy consumption, exterior ...

Problems solved by technology

The cement concrete industry not only consumes a lot of energy and resources, but also emits a lot of CO 2 and NO seriously pollute the environment; on the other hand, due to the rapid development of the construction industry, construction waste piles up like mountains, and the environmental problems caused are also obvious; on the other hand, the current wall materials generally still use natural stone and sand, resulting in mountain destroyed, with landslides and even river diversions

Although the external wall insulation technology can significantly save building energy consumption, the external wall insulation materials have potential safety hazards such as easy cracking, water seepage, poor safety performance, easy fire and falling off.
