Method for manufacturing high-stability solid wood composite floor by odd-even-symmetry assembling

Abstract

The invention relates to a method for manufacturing a high-stability solid wood composite floor by odd-even-symmetry assembling. The manufacturing method comprises the following steps: (1) preparing a base material, namely selecting a wood veneer of which the water content is 6% to 12%, and sequentially carrying out glue distribution, assembling, cold pressing and hot pressing to obtain the base material, wherein the assembling adopts an 'odd-even-symmetry' mode, specifically, odd layers adopt wood veneers which all are the same in factors, even layers adopt the wood veneers which all are the same in factors, and the factors include water content, texture, varieties of trees and thickness; (2) coating the surface; (3) forming a mortise; (4) coating and decorating the surface; and (5) sealing edges. The high-stability solid wood composite floor manufactured by the method provided by the invention is low in formaldehyde emission, uniform in water content, good in size stability, excellent in waterproofness, stable in effects and capable of effectively solving deformation problems such as dry shrinkage and wet expansion of the floor.

Description

technical field [0001] The invention relates to a method for preparing high-stability solid wood composite flooring from odd-even symmetrical blanks, and belongs to the technical field of solid wood composite flooring processing. Background technique [0002] Flooring is used as an interior decoration product in thousands of households. However, complaints about cracking and warping of floors are common in the market. Most of the problems are caused by uneven moisture content in the process of floor preparation and use. In response to the above quality problems, manufacturers usually use the following four methods to treat the floor to achieve a certain waterproof effect: [0003] (1) Edge banding: as described in the application number CN200520060045.4, a protective layer of paraffin wax is sprayed on the grooves and tenons on the side of the floor. The paraffin wax has good waterproof effect and high adhesion. This method is also widely used, but Paraffin wax is expensive...

Problems solved by technology

[0003] (1) Edge banding: as described in the application number CN200520060045.4, a protective layer of paraffin wax is sprayed on the grooves and tenons on the side of the floor. The paraffin wax has good waterproof effect and high adhesion. This method is also widely used, but Paraffin wax is expensive, poor in stability, and easy to solidify. It is easy to pollute the surface of the board during the spraying process and is difficult to remove, thus affecting the appearance of the floor surface

Therefore, some enterprises develop new waterproofing agents to replace expensive paraffin, such as a laminated floor edge sealer disclosed in the application number CN201010219782.X, which is mainly prepared by mixing beeswax, resin, ester solvent and alkane solvent, and A kind of non-degradable corn starch glue disclosed in CN201310125807.3, etc., the waterproof agent developed by the enterprise is various, and it is developed towards the research direction of low price, excellent waterproof performance, and green environmental protection, but its validity period is unstable, easy to lose or fail

In addition, some enterprises directly seal the side of the floor in the finishing process. Although it can temporarily play a certain waterproof role, the paint film is very brittle. Once it cracks and falls off, it will not only affect the appearance of the product, but also lose the waterproofing of the end surface. As a result, the floor will still be damp and deformed

[0004] (2) Add waterproof interlayer: a waterproof and soundproof floor as described in CN201320511513. high

For example, application numbers CN201210205108.5, CN201110183883.0, etc. have a variety of lock designs with complex structures. According to production practice, the more complex the lock, the higher the cost and the smaller the tensile strength, which will still cause seizure. Excessive gaps, tripping, damage to locks, etc.
