preparation example Construction

[0044] The preparation of the modified halloysite nanotubes is as follows: the amido-modified halloysite nanotubes are reacted with an organic modifier under the conditions of cuprous chloride and pentamethyldiethylenetriamine as a catalyst, and the organic The double bond at one end of the modifying agent molecule can cross-link and polymerize with the carbon atom adjacent to the amide group in the amide-modified halloysite nanotube to form a polymer coating on the surface of the halloysite nanotube.

[0045] When the existing cement waterproof and anti-cracking mortar is in a humid and low-temperature environment on the water surface, the hydration reaction of the mortar is incomplete, which limits the physical performance of the mortar in all aspects and greatly limits its application. The modified halloysite nanotubes prepared by the present invention can combine with Ca(OH) in the cement hydration product due to containing multiple active groups. 2 Generate gel substances...

Abstract

The invention relates to a waterproof and crack-resistant exterior wall thermal insulation structure of a building, which comprises a first waterproof and crack-resistant layer, a thermal insulation layer, and a second waterproof and crack-resistant layer arranged in sequence close to the wall, and the thermal insulation layer is located between the first waterproof and crack-resistant layer and the second waterproof and crack-resistant layer. Between the two waterproof and anti-crack layers; wherein, 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 composed of the following components in parts by weight: 100 parts Portland cement, 500-650 parts of medium sand, 90-110 parts of water, 32-66 parts of fly ash, 10-30 parts of modified halloysite nanotubes, 8-24 parts of polypropylene fiber, 3-10 parts Redispersible latex powder and 1-3 parts of water reducer. The waterproof and crack-resistant mortar material can reduce the construction steps of the product, and can ensure a more accurate and stable product shape, making the construction process faster and more efficient.

Description
