Plastering mortar for phenolic foam heat-insulating plate

The invention relates to the field of building material heat-insulating plates, and particularly discloses a plastering mortar for a phenolic foam heat-insulating plate. The raw materials comprise redispersible powder, ground calcium carbonate, fumed silica, silica fume, fine river sand, wood fiber and cellulose ether. When a wall body is stuck, in the set time, after a compound alkaline-resistant fiberglass roving cloth (containing a hot galvanizing steel mesh) is smeared through the plastering mortar for the phenolic foam heat-insulating plate, the bonding strength of the plastering mortar and the phenolic foam heat-insulating plate is high, and the formed plastering layer can resist acid, ageing, collision, rain permeation, cracking and the like, and meanwhile is provided with a multifunctional thin plastering protecting layer with certain elasticity and the like, so that the service life of the external heat-insulating system of an external wall is prolonged.
