Anion solid wood composite floor

Abstract

The invention discloses an anion solid wood composite floor, which consists of a backboard, a core board, an anion-impregnated fiber layer and a surface layer through interlayer compounding from bottom to top, or sequentially from bottom to top by a backboard, anion-impregnated The rubber fiber layer, the core board, the anion-impregnated fiber layer and the surface layer are compounded between layers to form a whole; the anion-impregnated fiber layer is pre-cured by impregnating the fiber layer in an adhesive containing anion powder. The fiber layer is plant fiber paper or non-woven fabric, and the negative ion powder is one or more of tourmaline powder, opal powder, seagull stone powder, hexacyclic stone powder, rare earth powder and meteorite powder capable of continuously releasing negative ions. The invention uses the anion-impregnated fiber layer as the buffer layer between the core board and the front and back boards, which can effectively avoid floor deformation caused by changes in environmental temperature and humidity. The formaldehyde in it is beneficial to human health.

Description

technical field [0001] The invention relates to the field of wood floors, in particular to an anion solid wood composite floor. Background technique [0002] At present, in the production of solid wood composite flooring, wood veneer is generally used as the buffer layer between the front and back boards and the core board, and the finished floor is formed by gluing with glue and hot pressing. There are two disadvantages of this method: First, when the wood veneer layer is used as the buffer layer, the wood veneer itself has defects such as scars and unevenness, which cannot solve the problems of the front and back boards. The deformation of the floor caused by the difference in stress between the core and the core board due to changes in ambient temperature and humidity; second, the core board is generally made of multi-layer wood veneers glued with multiple layers of resin containing formaldehyde, resulting in the release of formaldehyde from the floor Although the amount...

There are two disadvantages of this method: First, when the wood veneer layer is used as the buffer layer, the wood veneer itself has defects such as scars and unevenness, which cannot solve the problems of the front and back boards. The deformation of the floor caused by the difference in stress between the core and the core board due to changes in ambient temperature and humidity; second, the core board is generally made of multi-layer wood veneers glued with multiple layers of resin containing formaldehyde, resulting in the release of formaldehyde from the floor Although the amount of formaldehyde can generally meet the national standard of E1 level, it is difficult to meet the needs of more and more consumers for high-quality environmentally friendly products, that is, the formaldehyde emission level meets E0 level.
