Ammonium polyphosphate aging-resistance modified air-entrained brick and preparation method therefor
The invention discloses an ammonium polyphosphate aging-resistance modified air-entrained brick and a preparation method therefor. The ammonium polyphosphate aging-resistance modified air-entrained brick is prepared from the following raw materials in parts by weight: 100-120 parts of desert sand, 20-30 parts of ceramic polishing slag, 35-45 parts of ordinary Portland cement, 8-10 parts of poultry bone meal, 4-6 parts of waste tire rubber powder, 3-5 parts of papermaking white mud and the like. The added raw materials such as organic silicon microspheres, waste tire rubber powder and calcium rosinate are compositely used, and the water absorption of the air-entrained brick can be greatly reduced, so that the air-entrained brick has excellent water resistance and is unlikely to be affected with damp, and thus the mildew resistance is also higher; and moreover, the air-entrained brick has higher compressive strength and anti-bending strength, and is long in service life, wide in application range and wide in market prospect. An added compound plasticizer consisting of di-iso-decylphthalate, beta-diketone and ammonium polyphosphate is matched with an ethylene-vinyl acetate copolymer, so that the aging resistance and processing performance are improved while the mechanical property is improved, the flexibility of cables is improved, and the ammonium polyphosphate has the effect in a condensed phase.
