Abstract
The invention discloses a preparation method of an environment friendly brick, belonging to the technical field of re-utilization of wastes. The invention aims at the problem that treating capacity of building waste residues in China is large so as to cause bulk deposition of solid wastes, in a traditional solution, the waste residues are applied to making bricks, due to the fact that the waste residues contain chemical substances such as sulfide, the chemical substances can react chemically with surface materials if the time is long, so that discoloration and deterioration of decorative materials occur, and attractive appearance of a building is influenced. The invention provides the environment friendly brick by the steps of smashing building waste residues and removing impurities such as metal, and evenly mixing with carbonized straw powder under the protection of helium, then adding substances such as sodium anthraquinone-2-sulfonate to remove the sulfide in the waste residues, the mass is light, and decorative materials are not influenced. Embodiments prove that the mass of the obtained environment friendly brick is 60-80% of the mass of a common brick, the strength of the environment friendly brick is 2 to 3 times that of the common brick, hazardous substances in air can be adsorbed, meanwhile air harm to human health after decoration is reduced, the building waste residues are fully utilized, and environmental pollution is reduced.
Description
Technical field
