preparation example Construction

[0044] The preparation of modified Elonan nanotubes is: the amide-based modified Elonin nanotube is reacted with an organic modifier under the conditions of chloride and fivell methyl diamine as a catalyst, organic The double bonds at one end of the modifier molecule can be associated with an amide-based modified Elonan tube to crosslink polymerization, forming a polymer, covering the surface of the Elonan nanotube.

[0045] The existing cement waterproof anti-cracking mortar is in a wet low temperature environment in the water, resulting in a hydration reaction of the mortar, thus limiting the physical properties of the mortar, making it greatly limited. The modified Eliman nanotubes prepared by the present invention can be capable of containing Ca (OH) in cement hydrated products due to a variety of active groups. 2 Generate gel substances such as hydrated organic calcium, filled the capillary holes of the mortar, promote the hydration of cement, refine the hole structure, reduc...

Abstract

The invention relates to a waterproof and anti-crack external wall insulation structure for a building. The waterproof and anti-crack external wall insulation structure comprises a first waterproof and anti-crack layer, an insulation layer and a second waterproof and anti-crack layer, wherein the first waterproof and anti-crack layer, the insulation layer and the second waterproof and anti-crack layer are arranged in sequence near a wall, the insulation layer is located between the first waterproof and anti-crack layer and the second waterproof and anti-crack layer, both the first waterproof and anti-crack layer and the second waterproof and anti-crack layer are prepared from waterproof and anti-crack mortar materials, and the waterproof and anti-crack mortar materials are prepared from the following components in parts by weight: 100 parts of portland cement, 500 to 650 parts of medium sand, 90 to 110 parts of water, 32 to 66 parts of fly ash, 10 to 30 parts of modified halloysite nanotubes, 8 to 24 parts of polypropylene fibers, 3 to 10 parts of redispersible latex powder and 1 to 3 parts of water reducing agents. According to the waterproof and anti-crack external wall insulation structure, the construction steps of a product can be reduced through the waterproof and anti-crack mortar materials, the accurate and stable appearance of the product can be guaranteed, and the construction process is rapid and efficient.

Description

Technical field [0001] The present invention relates to the field of house buildings, and in particular, a building waterproof anti-cracking exterior wall insulation structure. Background technique [0002] With the economic development and the continuous improvement of people's living standards, the requirements for building quality are also increasingly high, and the market demand for high-performance new building structures is more intense. Building heat insulation is an important aspect of saving energy, improving living environment and functions, building exterior wall insulation structures can reduce or reduce the heat loss of buildings, thereby playing insulation effect, and its development and development have received more and more Pay attention. However, the traditional building exterior wall insulation structure has defects in waterproof and crack resistance. In the practical application, cracks, leakage, etc. are often produced, and the engineering quality, performanc...
