Embodiment l

[0024] A method for producing low-formaldehyde solid wood composite flooring, the steps are as follows:

[0025] (1) Rotary sheet of wood board: use a rotary cutter to cut the board to obtain a veneer, and pick out unqualified boards with insect eyes, decay, and excessive defects;

[0026] (2) Drying: Dry the veneer with a dryer to reduce the moisture content of the board to below 12%;

[0027] (3) Repair: Repair the defects or blemishes on the veneer including natural cracks, cracks, knots, skins and knots;

[0028](4) Material selection: Among the obtained veneers, the veneer used for the plywood is made of oak veneer; the middle plate and bottom plate are made of camphor veneer;

[0029] (5) Glue application: Use a glue applicator to apply glue to the surface plate, middle plate and bottom plate and assemble the billet. The glue solution is low-aldehyde urea-formaldehyde resin glue, and the amount of glue on one side is 220-235g / m 2 ;

[0030] (6) Pre-pressing: pre-press...

Abstract

The invention relates to a solid wood composite floor, in particular to a production method for a low-formaldehyde solid wood composite floor. The production method comprises the technological steps of wood plate slicing, drying, repairing, selecting, gluing, pre-pressing, hot pressing, edge cutting and sanding, and finished product obtaining. The key of the production method is that the residual amount of formaldehyde in adhesives is reduced by modifying the used urea-formaldehyde resin adhesives, so that the residual amount of the formaldehyde in the solid wood composite floor is reduced; by adopting high-quality plates and controlling process parameters in the production process, the quality of the produced solid wood composite floor is guaranteed. The content of the formaldehyde in the solid wood composite floor manufactured through the method is low, the quality of the floor is stable, and the floor is not prone to damage; the floor has the characteristics of being comfortable in foot feeling, resistant to abrasion, easy to install and clean, and high in stability.

Description

technical field [0001] The invention relates to a solid wood composite floor, in particular to a production method of a low-formaldehyde solid wood composite floor. Background technique [0002] With the development of China's economy and the improvement of people's living standards, the requirements for home decoration are also constantly increasing. Because of its natural and beautiful texture and good texture, wooden floor has become the first choice material for home floor decoration. Solid wood composite flooring overcomes the shortcomings of solid wood flooring swelling and shrinking, has good dimensional stability, and at the same time retains the natural wood grain and comfortable foot feeling of solid wood flooring, thus becoming an important variety in flooring. Solid wood composite flooring is made of cross-laminated boards of different tree species, which overcomes the disadvantage of unidirectional isotropy of solid wood flooring, has a small dry shrinkage and ...
