Abstract
The invention relates to a multilayer finger joint waterproof solid wood floor. The multilayer finger joint waterproof solid wood floor comprises a finger joint board layer, a first solid wood veneer layer arranged on the upper surface of the finger joint board layer, a second solid wood veneer layer arranged on the lower surface of the finger joint board layer, a solid wood surface board arranged on the first solid wood veneer layer, and a solid wood back board layer arranged under the second solid wood veneer layer. Fibers of every two adjacent layers form a criss-cross structure in the length direction. The multilayer finger joint waterproof solid wood floor has the advantages of being good in waterproof performance, free of deformation, free of warping, free of cracks in a humid environment, and long in service life.
Description
Technical field
The present invention relates to the technical field of wood flooring, be specifically related to a kind of multilayer finger Waterproof Wooden Floor Block with waterproof, anti-deformation function.
Background technology
The floor has been widely used in family and all kinds of public place as a kind of building and ornament materials, and particularly application square or the rectangle wooden floor is more and more wider.Because each finished product solid wood floor block has certain length, width and thickness requirement.In the manufacturing process of wood flooring, have many leftover pieces that do not reach specific length, can not be made into the floor board block of monoblock, the finger plate arises at the historic moment for this reason.The finger plate is to be formed by the polylith wood board splicing, owing to adopt the zigzag interface between vertical plank, the butt joint of similar two hand fingers intersection is so claim the finger plate.Finger processing is a complete part in the timber industry production and processing, and it reuses leftover pieces and environment amenable feasible production method for the timber industry provides.Because intensity and the presentation quality of finger plate sheet material have obtained improvement, thereby have been subjected to consumers in general's approval, yet owing to be subjected to splicing the restriction of intensity, make moist easily and produce phenomenons such as harmomegathus, warpage, cracking.For this reason, existing safeguard procedures are to apply one deck waterproofing membrane or water-repellent paint at the back side of wood substrate.Though can play moisture-proof role, ought be in for a long time under the environment of humidity or ponding, still inevitably deform, phenomenon such as warpage and cracking.
Summary of the invention
In order to solve the above-mentioned technical problem that prior art exists, the object of the present invention is to provide a kind of good waterproof performance that has, and under wet environment, indeformable, warpage does not take place, do not ftracture the multilayer finger Waterproof Wooden Floor Block of long service life.
