[0007] As disclosed in the patent literature of publication number CN102649866A: "a kind of phenolic foam, this phenolic foam is made by foamable phenolic resin, surfactant, modified calcium carbonate, filler, and curing agent, and described modified carbonic acid Calcium is selected from polyacrylate emulsion modified calcium carbonate, rosin modified calcium carbonate, solid paraffin modified calcium carbonate and thermoplastic phenolic resin modified calcium carbonate. Phenolic foam has the characteristics of energy saving, environmental protection, and corrosion resistance. However, the phenolic foam material generally has the defect of low mechanical strength, which leads to poor impact resistance of the external wall insulation system, thus limiting the use of phenolic foam materials in external wall insulation. application in the system

Abstract

The invention discloses an energy-saving environment-friendly building curtain wall and an installation method thereof. The energy-saving environment-friendly building curtain wall comprises a bonding layer, a phenolic foam board, a plastering layer and a decoration layer in a direction from inside to outside of a base-layer wall body. The phenolic foam board is prepared by the method comprising the following steps: 1) carrying out primary mixing on zeolite powder, carbon fibers, a silane coupling agent and a solvent to prepare a first mixture; 2) carrying out secondary mixing on a polyurethane prepolymer, a dispersing agent and the first mixture, and then adjusting the pH value of the formed system to be greater than 7 to prepare a second mixture; and 3) sequentially performing tertiary mixing, foaming and curing on phenolic resin, a surfactant, a filler, a curing agent, a foaming agent and the second mixture to obtain the phenolic foam board. The energy-saving environment-friendly building curtain wall has excellent mechanical strength.

Description

technical field [0001] The invention relates to a building curtain wall, in particular to an energy-saving and environment-friendly building curtain wall and an installation method thereof. Background technique [0002] The building curtain wall is the outer wall enclosure of the building. It is not load-bearing and hangs up like a curtain, so it is also called "curtain wall". It is a light-weight wall with decorative effect commonly used in modern large-scale and high-rise buildings. It is composed of panels and supporting structure systems, has a certain displacement capacity relative to the main structure or has a certain deformation capacity itself, and does not bear the role of the main structure. The building envelope structure or decorative structure (the external wall frame support system is also a part of the curtain wall system A sort of). [0003] Architectural decorative curtain walls have been used in construction projects as early as 150 years ago (in the midd...
