Back side dampproof and impervious structure of indoor wall of building

Abstract

The invention discloses a back side dampproof and impervious structure of an indoor wall of a building. The structure is composed of a base material layer, a dampproof surface layer and a decoration surface layer. The base material layer is a concrete base face or a cement mortar screeding layer. The decoration surface layer is coatings or wallpaper or wall cloth or a decoration panel or tile stone and the like. The dampproof surface layer is made of one or more layers of inorganic scale water-borne epoxy resin coatings. The inorganic scale water-borne epoxy resin coatings are composed of first components and second components, and the first components are epoxy resin dispersoid and comprise, by weight, 60 percent to 80 percent of bisphenol low molecular weight liquid epoxy resin, five percent to ten percent of reactive diluents, 0.2 percent to 1.0 percent of dispersing agents A, 0.05 percent to 0.1 percent of antifoaming agents A, 0.2 percent to 0.8 percent of non-ionic surface active agents, 0.1 percent to 0.2 percent of sinking preventing agents, eight percent to 40 percent of physical face packing and five percent to 20 percent of inorganic scale materials. The second components are hydrophilic waterborne curing agent dispersoid and comprise, by weight, 43 percent to 65 percent of modified aqueous amine curing agents, 34 percent to 60 percent of water, 0.2 percent to 0.4 percent of dispersing agents B, 0.2 percent to 0.5 percent of antifoaming agents B and 0.2 percent to 0.8 percent of flatting agents.

Description

technical field [0001] The invention relates to the technical field of waterproofing and moisture-proofing of building enclosure structures, in particular to a moisture-proof and anti-seepage structure on the backside of a building interior wall with a simple structure. Background technique [0002] The outer protective structure wall of the house building in our country is generally constructed of masonry double-sided composite mortar screed layer, insulation layer and decorative surface layer such as red brick, lime-sand brick or aerated concrete block. The leveling mortar of the inner and outer walls is generally made of ordinary 32.5 Portland cement and quartz sand mixed in a ratio of 1:2.5; the insulation layer is generally made of perlite or vitrified microbead insulation mortar, and polystyrene is also used in the north. Board composite anti-cracking mortar hanging nets and other methods; the outer decorative layer materials are mainly paint, stone or ceramic tiles, e...

Problems solved by technology

[0005] In the current national standards and technical specifications for building construction and decoration in China, only the water-facing surfaces of the exterior walls, roofs, and kitchens and bathrooms in the building envelope are treated with waterproof or moisture-proof treatment, while the surfaces of other building envelopes are treated Without any waterproof and moisture-proof measures and structures, the decorative surface layer is directly attached to the concrete or cement mortar substrate layer. Once the wall seeps and channels water, the decorative surface layer attached to the substrate layer will be destroyed by water
