Multifunctional interface polymer cement sheet and manufacturing method thereof

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 interface polymer cement sheet applied in the field of construction and a manufacturing method thereof. Background technique [0002] At present, the bonding interface of some building components used in the construction field at home and abroad often appears surface cracking, falling off, and even damage to the component body due to the influence of various factors, which causes the hidden danger of building safety to double. The concrete manifestations are as follows: 1. In the external wall thermal insulation project and its decoration project, the pasted thermal insulation board and decorative board (brick) often fall off from the building exterior wall; 2. The cement plastering of the wall of the building envelope Surface cracking, hollowing, and cracking will occur in the layer, thermal insulation leveling layer, facing layer, roof concrete waterproof layer, etc.; 3. Partition joints, expansion joints, deform...

AI Technical Summary

Problems solved by technology

[0005] Aiming at quality problems such as detachment, hollowing, cracking and poor bonding caused by temperature stress in the bonding performance of the interface of building components, it is difficult to control the quality of the commonly used treatment methods for this problem at present ( construction technology is strong), the purpose of the present invention is to provide a multifunctional interface polymer cement sheet for buildings, the multifunctional interface polymer cement sheet can better solve the problems existing in the prior art The following defects: 1 is the phenomenon that the pasted insulation boards and decorative boards (bricks) often fall off from the building exterior wall in the external wall insulation project and its decoration project; 2 is the wall cement plastering of the building enclosure structure Surface cracking, hollowing, and cracking of the concrete layer, thermal insulation leveling layer, finishing layer, roof concrete waterproof layer, etc.; 3 is the grid joints, expansion joints, deformation joints and pointing joints bonded to the concrete components Shedding, cracking, hollowing, and peeling between materials, caulking materials, caulking materials, potting materials, etc.
