The invention belongs to the technical field of building materials, and concretely discloses protective surface mortar. The protective surface mortar comprises the following components, by mass: 200-450 parts of cement, 350-750 parts of fine sand, 10-40 parts of redispersible latex powder, 10-50 parts of heavy calcium carbonate, 1-5 parts of polypropylene short fibers, 1-8 parts of hydroxypropyl methyl cellulose, 1-15 parts of a water reducer and 1-8 parts of a polymer water repellent. The protective surface mortar of the invention has good bonding strength, flexibility and water resistance, is convenient in construction, non-toxic, green and environmentally friendly, and can be applied to an external wall insulation system to effectively reduce wall cracking, water leakage, peeling, stripping, falling off and the like.
Description
technical field [0001] The invention belongs to the technical field of building materials, and specifically discloses a protective surface layer mortar. Background technique [0002] The energy consumption of China's construction industry accounts for almost 40% of the total industrial energy consumption. It is a long-term and arduous historical task to reduce the energy consumption of the construction industry and strive to improve the living comfort of buildings. The scale of China's buildings is huge, and the main structure of the building is mainly heavy. Under the condition of leapfrog development of building energy conservation, wall insulation technology is a thermal insulation and energy-saving technology with broad application prospects. [0003] The thin plaster insulation system of thermal insulation board is widely used in the internal and external wall insulation system, which uses extruded polystyrene foam board (referred to as XPS board) or expanded polystyren...
