Anti-seepage waterproof anti-cracking unfired hollow brick and preparation method thereof
The invention discloses an anti-seepage waterproof anti-cracking unfired hollow brick. The invention is characterized in that the unfired hollow brick is prepared from the following raw materials in parts by weight: 30-35 parts of coal gangue, 10-12 parts of ordinary Portland cement, 1-1.2 parts of alunite powder, 1-1.5 parts of sodium pyrophosphate, 3-5 parts of emulsified asphalt, 0.8-1 part of 3% potassium methylsilicate, 15-18 parts of limestone, 9-13 parts of intumescent vitrified microbead, 20-24 parts of clay, 15-18 parts of synergist and a right amount of water. The formula is scientific and reasonable; and under the combined actions of the alunite powder and cement, the mixture has favorable waterproof and anti-cracking effects. By adding the emulsified asphalt and 3% potassium methylsilicate, the brick has favorable waterproof and anti-seepage effects and favorable air permeability; and by compounding the intumescent vitrified microbead, the brick is air-permeable and thermally insulating. By adding the synergist, the brick has the characteristics of light weight, high strength, water resistance, thermal insulation and bacteria resistance. By adopting the unfiring technique, the brick has the advantages of energy saving, consumption reduction and emission reduction, and has favorable anti-seepage, waterproof, thermal-insulation, air-permeable and antiseismic effects.
