Composite decoration board of surface of stone

Abstract

A decorative composite plate with stone surface is composed of stone surface layer, adhesive layer and substrate which may be aluminium-plastics plate, plywood, or stone slab. Its features are that said substrate has many through holes in different shapes for preventing deformation and cracking caused by the temp or humidify variation. Its advantages are high stability, light weight, good toughness and no deformation.

Description

Technical field [0001] The invention relates to a decorative board, especially a composite decorative board with a stone surface. Background technique [0002] At present, the composite decorative panels with stone surface on the market are basically composed of stone panels, adhesive layers and bottom panels. Using high-quality and high-grade stone slabs, it overcomes its shortcomings of being fragile and has the advantages of light weight and low cost. However, due to the difference in physical properties between the stone panel and the floor, and the large-area bonding of the planar bonding method itself has poor deformation resistance, especially the difference in thermal expansion and contraction and water absorption, it is easy to cause deformation of the stone panel. If the glue is loose, it will seriously cause the stone panel to fall off. When the area of ​​the stone panel is large, the above phenomenon is more prominent, which affects the appearance and also leav...

AI Technical Summary

Problems solved by technology

However, due to the difference in physical properties between the stone panel and the floor, and the large-area bonding of the planar bonding method itself has poor deformation resistance, especially the difference in thermal expansion and contraction and water absorption, it is easy to cause deformation of the stone panel. The glue is loose, which seriously causes the stone panel to fall off

When the area of ​​the stone panel is large, the above phenomenon is more prominent, which affects the appearance and leaves a safety hazard, which seriously affects the popularization and use of composite decorative panels.

The Chinese utility model patent specification whose authorized notification number is CN 2387175Y also discloses such a composite stone slab, which is composed of a layer of natural stone slab and an aluminum corrugated board interlayer liner bonded to it. Although the composite stone slab It has the advantages of light weight, low cost, and not easy to break, but it still cannot overcome the problems of deformation of the stone panel and easy loosening of the glue with the bottom plate

In addition, in production practice, some stone panels are cut into small sizes and then pasted on the bottom plate with adhesives. Although this solution increases safety, it wastes a lot of manpower and material resources, and the effect of popularization and use is not obvious.
