Method for making sintered filled self-insulating block or wallboard

Abstract

The invention discloses a production method of a sintered-filled self-insulation building block or wallboard. The production method comprises the following steps: adding cement and water into crushed construction waste or coal ash, uniformly mixing, then adding cellulose and a foaming agent, with the added amount of cellulose being 0.5-3% of the total mass and the added amount of the foaming agent being 1-5% the total mass, and uniformly mixing to obtain an insulation filling material; filling up the cavity of the building block or the wallboard with the insulation filling material, and naturally curing or curing by heating, thus obtaining the filled self-insulation building block or wallboard. According to the production method disclosed by the invention, the construction waste is used for resource utilization, thus turning waste into wealth; a wall body has an excellent insulation performance, is a real green and energy-saving building block, plays good energy-saving and emission-reducing roles, and meets the need of building energy conservation; the thickness of the wall body is reduced, sand rubbing does not need to be carried out at the outer side and the inner side of the wall body, the glaze surface of the wall body is directly used as an outer wall surface, and an inner cavity coating is directly brushed on the inner side surface of the wall body, thus furthest reducing working procedures and saving various building materials.

Description

technical field [0001] The present invention relates to a method for making building bricks, blocks and wallboards, in particular to a sintered-filled self-insulating masonry with high thermal insulation performance and using construction waste soil or fly ash to make bricks, blocks and wallboards. Method of making blocks or panels. Background technique [0002] The amount of construction waste in my country has accounted for 30%-40% of the total amount of urban waste. Calculated on the basis of 500-600 tons / 10,000 square meters, by 2020, my country will add about 30 billion square meters of new construction area, and the newly generated construction waste will be a shocking number. However, the vast majority of construction waste is transported to the suburbs or villages by the construction unit without any treatment, and is stacked in the open air or landfilled, which consumes a lot of construction expenses such as land acquisition fees, garbage removal and transportation...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the purpose of the present invention is to solve the problems that existing bricks and building blocks do not use or use less construction waste, do not utilize it as resources, require land to be stacked, and waste precious land resources. , providing a method for making sintered filled self-insulating blocks or wall panels
