Abstract

The invention discloses an insulating environment-friendly brick and a preparation method thereof, which relates to the technical field of bricks. The insulating environment-friendly brick is preparedfrom the following raw materials in parts by weight: 50 to 60 parts of mineral slag silicate cement, 30 to 40 parts of waste cement brick powder, 20 to 30 parts of coal gangue, 15 to 30 parts of an adhesion aid, 6 to 12 parts of dicumyl peroxide, 12 to 18 parts of carbonized crop straw powder, 10 to 14 parts of magnesium oxide, 8 to 14 parts of barium stearate, 4 to 8 parts of lignin, and 2 to 5parts of triethanolamine. The preparation method of the brick comprises the following steps: preparing coal gangue powder, preparing cement mortar, molding by using a mold, and performing maintenance.The insulating environment-friendly brick is excellent in insulating performance; and by adopting a great amount of waste produced in daily life as a raw material, the cost can be reduced, and the environment can be protected.

Description

technical field [0001] The invention belongs to the technical field of bricks, and in particular relates to a thermal insulation and environment-friendly brick and a preparation method thereof. Background technique [0002] Thermal insulation and environmental protection bricks are mainly used in wall materials, and consume a huge amount. In the prior art, cement and sand are mainly used for preparation. With the gradual consumption of resources, the cost of materials is also getting higher and higher. There is an urgent need to find other alternative materials to save the development and utilization of raw materials; in addition, in addition to large consumption and high cost, the performance requirements for bricks themselves are also increasing, but the current wall bricks still have low compressive strength. , Poor thermal insulation effect and large energy consumption. [0003] The Chinese invention patent application with the publication number CN105967636A discloses ...
