Abstract
The invention provides a flexible flame-retardant facing brick which has the characteristics of energy conservation and environmental protection, and also has good flexibility; and meanwhile, the flexible flame-retardant facing brick has good matching performance with different wall base layers or insulation materials, and thus the dropping of the facing brick caused by the displacement stress between the facing brick and a wall due to the temperature variation can be avoided. The flexible flame-retardant facing brick also has good air permeability, external water is prevented from entering the facing brick, and the evaporation of the vapor inside the facing brick is facilitated; although the polymer emulsion is used as a cementing material of the facing brick, the consumption of the polymer emulsion is little; and meanwhile, due to the action of a modified flame-retardant agent, the flame-retardant performance of the facing brick is better than that of a similar product.
