Novel composite honeycomb board

Abstract

The invention provides a novel composite honeycomb board characterized by light weight, high strength, good fireproof performance and good energy-saving and thermal insulation effects. The novel composite honeycomb board comprises a panel (1), a first composite honeycomb core layer (2), a separating layer (3), a second composite honeycomb core layer (4), and a backplane (5) from top to bottom in order. The 5 structural layers are bonded by a two-component polyurethane adhesive. The first composite honeycomb core layer (2) and the second honeycomb core layer (4) are formed by bonding of a plurality of hexagonal honeycombs integrally shaped by an aviation resin matrix composite material. And the size of bee holes on the first composite honeycomb core layer (2) is smaller than that of the bee holes on the second composite honeycomb core layer (4).

Description

technical field [0001] The invention relates to the field of building boards, in particular to a novel honeycomb composite board. Background technique [0002] Commonly used composite panel honeycomb panel technology in the field of construction engineering, such as paper honeycomb, glass fiber reinforced plastic honeycomb and aluminum honeycomb, paper honeycomb panel itself has very low strength, is not resistant to moisture and is easy to age, and has poor flammability and fire resistance. FRP honeycomb has low impact strength and is easy to age; aluminum honeycomb panels are made of aluminum honeycomb cores and aluminum alloy panels. Stiffness, which increases the self-weight of the honeycomb panel. However, when honeycomb panels are used as building exterior walls or partitions, no matter whether it is paper honeycomb, fiberglass honeycomb or aluminum honeycomb, they cannot withstand large longitudinal impacts, and the above-mentioned honeycomb panels cannot guarantee g...

Problems solved by technology

[0002] Commonly used composite panel honeycomb panel technology in the field of construction engineering, such as paper honeycomb, glass fiber reinforced plastic honeycomb and aluminum honeycomb, paper honeycomb panel, its own strength is very low, not resistant to moisture and easy to age, and has poor flammability and fire resistance

FRP honeycomb has low impact strength and is easy to age; aluminum honeycomb panels are made of aluminum honeycomb cores and aluminum alloy panels. Stiffness, which increases the self-weight of the honeycomb panel

However, when honeycomb panels are used as building exterior walls or partition layers, no matter whether it is paper honeycomb, fiberglass honeycomb or aluminum honeycomb, they cannot withstand large longitudinal impacts, and the above-mentioned honeycomb panels cannot guarantee good sound insulation and heat insulation.
