preparation example Construction

[0035] The present invention also provides a preparation method for the lightweight building curtain wall panel described in the above technical solution, comprising the following steps:

[0036] 1) Provide several flat plates;

[0037] 2) Provide several hollow-structure plates; the number of the flat plates is one more than the number of hollow-structure plates;

[0038] 3) Alternately laminating the flat boards and hollow-structured boards, and applying an adhesive between adjacent boards, and then performing hot pressing to obtain a core layer;

[0039]4) a first surface layer is set on one side of the core layer, and a second surface layer is set on the other side of the core layer to obtain a lightweight building curtain wall panel;

[0040] Steps 1) and 2) are not limited in chronological order.

[0041] The present invention firstly provides several flat boards and several hollow-structured boards; the number of said flat boards is one more than the number of hollow-...

Embodiment 1

[0048] In this embodiment, a bamboo-wood composite honeycomb panel with a height of 10mm is used as a hollow structural panel, and as a lightweight layer unit, a bamboo flat panel with a thickness of 2.5mm is used as a base unit, and the first surface layer and the second surface layer are made of fluorocarbon paint. membrane;

[0049] Lay two bamboo-exposed panels and one bamboo-wood composite honeycomb panel in order from top to bottom: bamboo-exposed panels, bamboo-wood composite honeycomb panels, and bamboo-exposed panels, and coat phenolic resin between adjacent two-layer panels Adhesive, the dosage of phenolic resin adhesive is 260g / m 2 , to obtain the core layer blank, and then hot press the core layer blank at a temperature of 150° C. and a pressure of 1.5 MPa for 1 min to obtain a core layer;

[0050] After the two surfaces of the core layer are subjected to surface sanding, edge grinding, edge sealing and waterproof coating in sequence, the two surfaces of the core ...

Embodiment 2

[0052] This embodiment adopts the bamboo-wood composite honeycomb panel with a height of 10mm as the hollow structural plate, and the bamboo tube rotary-cut board with a thickness of 1.2mm is used as the base unit, and the first surface layer and the second surface layer adopt a coated ceramic coating film; wherein the bamboo tube rotary The cutting board is prepared by the following steps: cutting the bamboo into a veneer to obtain a thin bamboo with a thickness of 0.6mm; mixing and stirring the thermal elastomer of the model G140D and the isocyanate adhesive to obtain a binder; the isocyanate adhesive Account for 15% of the total mass of the binding material; the binding material is coated on the micro-thin bamboo surface, wherein the coating quality of the binding material is 0.6 times of the quality of the thin bamboo, and another piece of micro-thin bamboo is coated with the micro-thin bamboo of the binding material. After the bamboo is laminated, it is hot-pressed for 2 m...

Abstract

The invention belongs to the technical field of building curtain wall plates, and particularly relates to a light building curtain wall plate and a preparation method thereof. The light building curtain wall plate comprises a first surface layer, a core layer and a second surface layer which are sequentially connected in a contact mode, wherein the core layer is composed of base layer units and light layer units which are arranged at intervals, and the number of the base layer units is one more than that of the light layer units; and the light layer units are plates of hollow structures, the plates of the hollow structures are made of bamboo-wood composite materials, and the base layer units are flat plates. According to the light building curtain wall plate and the preparation method thereof, the light units are made of the hollow structure materials, the self-weight of the building curtain wall plate is reduced, meanwhile, the buffering performance of the building curtain wall plate is remarkably enhanced, and the use safety is improved.

Description

technical field [0001] The invention belongs to the technical field of building curtain wall panels, and in particular relates to a lightweight building curtain wall panel and a preparation method thereof. Background technique [0002] The building curtain wall is the outer wall enclosure of the building, which does not bear the load of the main structure of the building. The building curtain wall usually consists of a decorative panel and a supporting structure behind it (metal components of the base plate, and metal beams and columns connected with the main body of the building, etc.). The building curtain wall is connected with the main structure of the building, generally using bolts, rocker arms, spring mechanisms, etc. to connect, which can produce a large relative displacement between the two, even when the main structure moves sideways to 1 / 60, the curtain wall does not will destroy. At the same time, the architectural curtain wall has good modeling ability and dec...
