Grouting material for balcony or roof waterproof layer reconstruction construction method and preparation method and application of grouting material

Abstract

The invention discloses a grouting material for a balcony or roof waterproof layer reconstruction construction method and a preparation method and an application of the grouting material. The groutingmaterial comprises a component A and a component B, wherein the component A is prepared from 30 to 40 parts of emulsified asphalt, 30 to 40 parts of an acrylate emulsion, 1.0 to 1.5 parts of a dispersing agent, 0.5 to 1.0 part of a defoaming agent, 0.25 to 0.75 part of bactericide, 10 to 30 parts of organic silicon water repellent, 5 to 10 parts of bentonite and 0.25 to 1.0 part of a coupling agent; the raw materials of the component B are the same as those of the component A, and the coupling agent is replaced with 0.25-1.0 part of the cross-linking agent; the grouting material is composed of the component A and the component B, is a flowing liquid before grouting, is good in groutability, and is cured into an elastomer within a certain period of time after grouting, so that all gaps andleakage channels in the middle of a structural layer are well filled. The grouting material disclosed by the invention is a brand-new grouting material and has the characteristics of good water resistance, no shrinkage, good elasticity, ultraviolet resistance and the like.

Description

technical field [0001] The invention belongs to a plugging grouting material for construction, in particular to a grouting material used in a construction method for rebuilding a waterproof layer of a balcony or a roof, and a preparation method and application thereof. Background technique [0002] There are often many gaps under the balcony tiles or the roof surface layer. For example, there is a layer of 3-5cm dry sand layer under the balcony tiles, and there is an insulation layer under the roof surface layer. The insulation materials are often porous materials. Once water penetrates into these gaps , it will form a leaking water source, coupled with the failure of the waterproof layer and the structural cracking, the water source will reach the room along the leakage channel, causing trouble to everyone's life. [0003] At present, there are two types of methods for treating such leakage. One method is to remove all the surface layers to the structural layer, re-make the...

Problems solved by technology

[0004] Purpose of the invention: Aiming at the problems existing in the prior art, the present invention provides a kind of grouting material for balcony or roof rebuilding waterproof layer construction method, and the grouting material of the present invention is a kind of grouting material for balcony or roof rebuilding waterproof layer construction method The material has the characteristics of good water resistance, no shrinkage, good elasticity and UV resistance; it solves the problem that the existing cement-based grouting liquid is easy to crack and cannot adapt to the deformation of the base layer; and the organic elasticity of acrylates The grouting fluid has low solid content, and it is easy to lose water and shrink in a dry environment, re-forming leakage channels, etc.
