Strengthening type three-layered wood compound floor board and mfg. method thereof

Abstract

The present invention relates to one kind of three-layer reinforced laminated wooden floor board and its making process. The three-layer reinforced laminated wooden floor board includes one surface wood layer, one core layer and one back layer adhered to the core layer, and has one chemical fiber non-woven fabric layer adhered between the core layer and the surface wood layer. The making process of the three-layer reinforced composite wooden floor board includes the following steps: making surface wood board, selecting core layer board, making back board, combination and pressing, splitting and balancing, and forming. Compared with available technology, the present invention has the advantages of raised adhesion strength, less cracking and high stability.

Description

technical field [0001] The invention relates to building decoration materials, in particular to a reinforced three-layer solid wood composite floor and a manufacturing method thereof. Background technique [0002] At present, the multi-layer solid wood composite floor is used in various places, because it has the characteristics of environmental protection, not easy to deform, good viewing effect, long service life, relatively cheap price, etc., so it is widely accepted by people, but the current solid wood composite floor Most of the core boards use density boards. For example, the utility model patent of "a solid wood composite laminated floor" with Chinese patent number 200420030659.9 uses high-density boards as the core layer in the five-layer structure. It is a wear-resistant paper impregnated with melamine, and a thin wood and a balance layer are pressed between the high-density core board; the Chinese patent number is 200320122776.8, a utility model patent for "a comp...

[0002] At present, the multi-layer solid wood composite floor is used in various places, because it has the characteristics of environmental protection, not easy to deform, good viewing effect, long service life, relatively cheap price, etc., so it is widely accepted by people, but the current solid wood composite floor Most of the core boards use density boards. For example, the utility model patent of "a solid wood composite laminated floor" with Chinese patent number 200420030659.9 uses high-density boards as the core layer in the five-layer structure. It is a wear-resistant paper impregnated with melamine, and the thin wood and balance layer are pressed between the high-density core board; the Chinese patent number is 200320122776.8, a utility model patent for "a composite floor", the core board is made of a solid wood base However, as a walking laminate of solid wood composite flooring, the bonding between the surface board and the density board is in use, and the surface board is easy to crack with the moderate change of the season, and the surface board and the core board are easy to crack.
