Organic adhesive water permeable brick and preparation method thereof

The invention provides an organic adhesive water permeable brick and a preparation method thereof, and the organic adhesive water permeable brick comprises a base layer and a surface layer; the base layer is prepared from the following raw materials in parts by weight: 70-80 parts of aggregate, 20-25 parts of cement, 5-8 parts of water, 0.3-0.5 part of a water reducing agent, 0.5-1 part of a cement reinforcing agent and 0.5-1 part of a shrinkage modifier; the surface layer is prepared from the following raw materials in parts by weight: 90-100 parts of round-grain silica sand, 2.5-3 parts of an organic adhesive, 0.8-1 part of a curing agent, 3-3.2 parts of a stabilizer, 1-2 parts of a coupling agent and 0.7-1.0 part of toner. The organic adhesive water permeable brick disclosed by the invention has better strength and bonding strength of a base layer and a surface layer while the original water permeable rate is not reduced, and a preparation forming process is simple and suitable for popularization. 本发明提供一种有
