Biomass carbon matrix environment-friendly brick and making method

Abstract

The invention discloses a biomass carbon matrix environment-friendly brick and a making method. The biomass carbon matrix environment-friendly brick is characterized by comprising the following components (in percentage by weight): 35-45% of biological black carbon, 55-65% of an earth material and 1-3% of molding aids, wherein the brick is made by treating the earth material, mixing with the biological black carbon, molding, drying and roasting; the biological black carbon is biological black carbon granules or powder ash made of biomasses via high-temperature carbonization; the earth material comprises 15-35% of clay, 15-25% of shale powder ash, 15-25% of coal gangue powder ash and 15-25% of coal ash; the 1-3% of molding aids comprise bentonite, fulvic acid powder and tapioca flour. The making method comprises the following steps: performing high-temperature carbonization on various types of biomass straw so as to obtain biological black carbon granules or powder ash; grinding shale, coal gangue and coal residues into a powder material; uniformly mixing with the clay and the molding aids; making bricks by using a brick making machine, drying, and sintering. Due to adoption of a biomass black carbon material, the biomass carbon matrix environment-friendly brick is capable of adsorbing toxic gases as a whole for a long time, is light and environmentally friendly, and is capable of purifying indoor polluted air and lowering cost.

Description

technical field [0001] The invention belongs to the field of building materials, relates to the comprehensive utilization of biomass straw and is environmentally friendly and livable, in particular to a biomass carbonized environmental protection brick and a preparation method thereof. Background technique [0002] In modern people's lives, one of the more serious threats is air pollution, which mainly comes from domestic garbage, mold, furniture, etc. indoors. Such as formaldehyde, TVOC, radon, etc. exist in the organic pollutants of indoor air, which are harmful pollutants, mainly from building materials, interior decoration materials and daily necessities, in various artificial plywood, blockboard, density For fiberboard and particleboard, the residual and unreacted formaldehyde in the board will be gradually released to the surrounding environment. In addition, decorative materials containing formaldehyde such as wall coverings, chemical fiber carpets, foam plastics, pa...

Problems solved by technology

[0006] The problem to be solved by the present invention is that sintered clay bricks limit the use of a large amount of clay, and there is a large amount of direct pollution in the living environment of people. It provides a kind of biomass carbon-based environmental protection brick and its preparation method. By utilizing the unique adsorption of biological black carbon, the biological black Carbon, clay and lime powder are processed to produce biomass environmental protection bricks, which are light and environmentally friendly, and can absorb harmful substances or gases as a whole for a long time, so as to purify indoor polluted air and reduce the cost of producing bricks
