The invention relates to a special repairing agent for a boiler flue gas desulfurization tower and a production process thereof. The repairing agent is a multi-layer composite coating, which comprises a wear-resistant layer, a bonding layer, a wear-resistant layer and a wear-resistant layer which are sequentially coated on the inner wall of the desulfurization tower from top to bottom. The corrosion-resistant layer and the corrosion-resistant layer are closely attached to the inner wall of the desulfurization tower. The total thickness of the repair agent is 1.8mm~2.5mm, of which the thickness of the wear-resistant layer is 0.5mm~0.6mm, the thickness of the bonding layer is 1mm~1.5mm, The thickness of the corrosion-resistant layer is 0.3mm~0.4mm. The repairing agent of the present invention forms a composite coating structure with an outer layer of anti-wear and an inner layer of anti-corrosion, and each coating will form an interpenetrating network structure during the curing process, so that all raw materials have a synergistic effect, and can effectively improve wear resistance, Corrosion-resistant performance, can well meet the needs of use. |
