The invention discloses an aging-resistant flexible aerated building block and a preparation method therefor. The aging-resistant flexible aerated building block is prepared from the following raw materials in parts by weight: 100-120 parts of desert sand, 20-30 parts of ceramic polished slag, 35-45 parts of ordinary Portland cement, 8-10 parts of poultry bone meal, 4-6 parts of waste/used tire rubber powder, 3-5 parts of white clay for papermaking, and the like. According to the aging-resistant flexible aerated building block and the preparation method therefor, the added raw materials such as organosilicon microspheres, the waste/used tire rubber powder, calcium rosinate and the like are used in a compounded manner, so that the water absorption rate of aerated bricks can be greatly lowered, the aerated bricks can have excellent water resistance and are not prone to wetting, and thus, the mildew resistance is relatively high; and in addition, the aerated building block disclosed by the invention further has relatively high compressive strength and bending strength, long service life, wide application range and broad market prospect. According to the aging-resistant flexible aerated building block and the preparation method therefor, a compounded plasticizer which is prepared from added diisodecyl phthalate, beta-diketone and ammonium polyphosphate is matched with an ethylene-vinylacetate copolymer, so that the aging resistance and processing performance are improved while mechanical properties are improved, and the flexibility is improved; and meanwhile, ammonium polyphosphate plays a role in condensing a phase.
