Heat insulating and sound isolating decorative corrugated composite board

Abstract

The invention relates to a building board, in particular to a heat insulating and sound isolating decorative corrugated composite board which comprises a metallic board and a metallic corrugated board, wherein a resin layer is respectively attached to the lower surface of the metallic corrugated board and the back surface of the metallic board; the metallic board and the metallic corrugated board are bonded and composited together between the resin layer on the lower surface of the metallic corrugated board and the resin layer on the back surface of the metallic board through a bonding agent; a heat insulating and sound isolating layer is also bonded on the upper surface of the metallic corrugated board; the heat insulating and sound isolating layer is a heat insulating and sound isolating board or sound isolating cloth; a resin layer is also arranged between the upper surface of the metallic corrugated board and the heat insulating and sound isolating layer; and the resin layer is attached to the upper surface of the metallic corrugated board. The heat insulating and sound isolating decorative corrugated composite board has higher strength and good surface smoothness and meets the national standards.

Description

【Technical field】 [0001] The invention relates to a building material, in particular to a board for decoration. 【Background technique】 [0002] At present, in the field of architectural decoration, there are more and more applications for metal sheets, especially when used in various high-end decoration occasions, the flatness and strength of the material panels are required to be high, and the strength of ordinary single-layer metal sheets is often None of them meet the requirements, so in actual use, in order to increase the strength, various metal composite panels are often used instead, such as honeycomb panels or ordinary corrugated composite panels. For example, the Chinese patent No. CN200520047093.X discloses a metal ceiling or wide-width decorative panel on the wall, which is composited by bonding or mechanically connecting the panel and the corrugated back panel. Although the strength of this composite panel is It has been improved, but the cohesive strength of th...

For example, the Chinese patent No. CN200520047093.X discloses a metal ceiling or wide-width decorative panel on the wall, which is composited by bonding or mechanically connecting the panel and the corrugated back panel. Although the strength of this composite panel is It has been improved, but the cohesive strength of the panel and corrugated board is low, and it still cannot strengthen the effect. At the same time, the way of its mechanical connection will destroy the flatness and surface paint of the panel, and it cannot meet the GJB130.7-86 national standard. Standard requirements, prone to safety hazards
