The invention discloses a waterproof agent for building mortar, and belongs to the technical field of building waterproof materials. The waterproof agent for building mortar comprises the following components in parts by weight: 20-40 parts of gypsum powder, 20-40 parts of sodium silicate, 5-15 parts of alum, 10-20 parts of sodium hydroxide, 10-30 parts of propyl trimethoxysilane, 10-20 parts of dimethyl dichlorosilane, 5-15 parts of iron powder, 5-15 parts of tween-80, 5-15 parts of span 80 and 50-100 parts of water. According to the invention, the gypsum powder is used to further compact the concrete structure under the effects of sodium silicate, sodium hydroxide and iron powder; the fluidity, filling capability and condensation speed of the waterproof agent are improved through alum, propyl trimethoxysilane, dimethyl dichlorosilane, tween-80 and span 80; since water is used as a solvent, the waterproof agent is environment-friendly, excellent in performance, simple in construction, good in anti-seepage performance and long in service life.
