Microporous sintered bricks with interface bonding improved by redispersable rubber powder

The invention discloses microporous sintered bricks sintered bricks with interface bonding improved by redispersable rubber powder. The microporous sintered bricks are made from, by weight, 40-43 parts of urban sludge, 8-9 parts of mesoporous silica, 22-25 parts of shales, 38-40 parts of coal gangue, 14-15 parts of rice husk, a proper amount of water, 2.5-3 part of potassium feldspar, 2-3 parts of paraffin, 0.8-1 part of polyvinyl alcohol, 2-3 parts of redispersable rubber powder and 11-13 parts of household garbage. The household garbage is added to green brick pug through a series of process modification, the microporous sintered bricks sintered bricks have stronger hydrophily by cooperating with the polyvinyl alcohol and the redispersable rubber powder, water molecules can be absorbed through compounding to form a layer of solvated water film having a certain mechanical strength, so that other raw materials on the surface of the household garbage can be fully hydrated, microcracks are filled through mutual
