Title:

NANO-MODIFIED MATERIAL FOR CAVITY WALL WITH INSULATION FOR PREFABRICATED BUILDING, AND PREPARATION METHOD AND USE THEREOF

Document Type and Number:

WIPO Patent Application WO/2021/008194

Kind Code:

A1

Abstract:

Disclosed are a nano-modified material for cavity wall with insulation for prefabricated building, preparation method and application thereof. The material comprises splicing structures and a nano-modified silane waterproof coating, wherein the splicing structure comprises a recycled concrete structure layer and a nano-modified foam concrete thermal insulation core layer. The recycled concrete structure layer is a hollow cuboid structure with openings at both ends, the nano-modified foam concrete thermal insulation core layer is a structure formed by casting inside the recycled concrete structure layer, and the nano-modified silane waterproof coating is applied at the butt joint of two of the splicing structures.
