Method for preparing foam glass brick based on boric sludge

Abstract

The invention relates to a method for producing foam glass mosaic based on boron sludge and pertains to the technical field of functional inorganic material. The invention is characterized in that the invention comprises the steps: waste glass is crushed, mixed with de-magging boron sludge according to ratio and grinded into green stock; the green stock is heated, quenched, dried and grinded into glass powder; certain amount of glass powder is mixed with vesicant, latent solvent and foam stabilizer to form foam glass layer material; certain amount of glass powder, pigment and complete fusion are mixed to form mosaic layer material; the mosaic layer material and the foam glass layer material are put into a die sequentially, pressed and molded and the foam glass mosaic is obtained after heating, foaming, foam stabilizing and annealing. The product of the invention is a bifunctional compound material, one layer of which is foam glass phase and other layer of which is mosaic phase, thus solving the problem that the foam glass can not be directly used as building material due to porosity and uneven color, moreover, the invention can reduce the cost of foam glass mosaic without wastes being discharged during the whole process, has greening and environment protective functions and pertains to environmental friendly technology.

Description

technical field [0001] The invention belongs to the technical field of functional inorganic materials, and relates to a method for producing foam glass mosaic tiles based on boron mud. Background technique [0002] Boron mud is the main waste discharged during the production process of extracting borax from boron ore or boron-magnesium ore in chemical plants. For every ton of borax produced, 3 to 4 tons of boron mud will be discharged. In my country, millions of tons of boron mud are discharged every year. Not only occupy a large amount of land, but also seriously pollute the environment. The main components of boron mud are magnesium oxide, silicon oxide, calcium oxide, iron oxide and boron-containing insoluble matter. The existing treatment method is to stack it in a certain area to limit discharge, and individual factories mix it with other components to prepare fired bricks, but the amount is very small. The more scientific method of the latest invention is to convert a...

Problems solved by technology

[0005] The effect and benefit of the present invention are that the foam glass mosaic tile is a dual-functional composite material with one layer of foam glass phase and the other layer of mosaic brick phase, which integrates heat preservation and decoration, and solves the problems caused by foam glass as a building decoration material. engineering stability and cost issues; in addition, the demagnesia boron mud particles are finer, and it is used to prepare foam glass mosaic tiles without grinding, which saves energy and reduces consumption; trace boron in the demagnesia boron mud can reduce the foaming temperature and make the flux The amount of addition is relatively reduced; another raw material used in the present invention is waste glass, which is conducive to circular economy and sustainable development; in addition, the whole process of the present invention has no waste discharge, which belongs to an environmentally friendly technology; the product of the present invention is widely used in construction external wall insulation system
