Abstract

The invention discloses a multifunctional interface polymer cement sheet and a manufacturing method thereof. The multifunctional interface polymer cement sheet includes a non-woven fabric (1), a flexible polymer cement cellular material layer (2) and a flexible polymer cement anti-permeability layer (3), wherein flexible polymer cement micro-bubble slurry is coated on the upper surface of the non-woven fabric (1), and the flexible polymer cement micro-bubble slurry is gelated and solidified to form the flexible polymer cement cellular material layer which is fitted with the non-woven fabric; an anti-permeability material is coated on the upper surface of the flexible polymer cement cellular material layer; the anti-permeability material permeates into pores in the upper surface layer of the flexible polymer cement cellular material layer, and is crystallized and expanded into anti-permeability material crystals (4) which are insoluble to water; and the flexible polymer cement anti-permeability layer is formed by the anti-permeability material crystals and the flexible polymer cement cellular material which interweaves with the crystals. The polymer cement sheet disclosed by the invention not only has excellent binding performances, but also has high strength, water permeability resistance and a function of loading external stress.

Description

technical field [0001] The invention relates to a multifunctional interfacial polymer cement sheet applied in the construction field and its preparation method. Background technique [0002] At present, the bonding interface of some building components used in the construction field at home and abroad often has surface cracking, falling off, and even damage to the component body due to the influence of various factors, resulting in doubled building safety hazards. The specific manifestations are as follows: 1. In the external wall insulation project and its decoration project, the pasted insulation board and decorative board (brick) often appear to fall off the building's exterior wall; 2. The wall cement plastering of the building envelope Surface cracking, hollowing, and cracking will occur in the layer, thermal insulation leveling layer, finishing layer, roof concrete waterproof layer, etc.; , caulking materials, caulking materials, potting materials, etc. appear to fall...
