Description

Floor surface board and its manufacturing method

technical field

The invention relates to a floor, in particular to a floor surface board and a manufacturing method thereof.

Background technique

The surface board of solid wood composite flooring is usually made of high-quality sawn (radius-cut, string-cut or rotary-cut) wood, and the materials are often hard broad-leaved wood that takes decades to more than a hundred years to become useful. In order to save precious broad-leaved wood, most of the current floor panels are made of precious broad-leaved wood with a thickness of 3 to 4 mm. However, with the promulgation of policies to protect forest resources in various countries in the world, the logging of precious and rare tree species is prohibited, and rare and rare tree species are used to make the surface of solid wood composite flooring. Therefore, different floor panels for floor coverings have appeared.

For example: LVL surface board, laminated veneer lumber (LVL) veneer made by rotary cutting, the blanks are assembled in sequence along the grain direction, the ends are mitered, lapped or butted, and then glued, hot pressed, etc. A high-strength structural material that is pressed by a process. The Finnish Raute company produces a three-layer composite floor sawn from laminated veneer lumber, which has good appearance and quality. According to Lauter Company, the market and price of this floor are as good as those of ordinary three-layer solid wood floor.

For example: Bamboo surface boards, splicing boards spliced with bamboo slices of fixed width, the thickness is generally 3.5~4 mm. It has the unique appearance texture and elegant and novel decorative effect of bamboo. At the same time, bamboo has the advantages of compact structure, high strength, good rigidity, high hardness, surface wear resistance and impact resistance.

For example: make full use of elm, catalpa, birch and other tree species to develop coniferous wood surface boards. Reduce dependence on high-quality tree species.

The above several materials have their own shortcomings as floor panels. LVL surface boards use a large amount of glue, so it is difficult to guarantee environmental protection, and its texture is far from precious wood; The humidity rises differently, so it is easy to crack the surface board, and the bamboo is easy to be eaten by insects; other tree species such as elm, catalpa, birch, etc. are used as the floor surface board, and its aesthetics and decorative effect are relatively poor.

Contents of the invention

The purpose of the present invention is to overcome the disadvantages of the existing solid wood composite flooring that use a large amount of natural precious wood, poor surface wear resistance, and burning resistance, and provide a floor that can simultaneously save wood resources and have the performance of strengthening the surface board of the floor Surface board; and provide a scientific and reasonable, easy-to-form, high-quality floor surface board manufacturing method.

The technical scheme that realizes the object of the present invention adopts is, a kind of manufacturing method of floor board, it is characterized in that, it comprises the following steps:

1) Substrate: use 3~4mm fast-growing wood veneer;

2) Substrate adhesive layer: Coat the surface of the substrate with melamine resin adhesive, the amount of melamine resin adhesive applied is 10g/m ² ~40g/m ² , and the temperature is 60~80℃, and the drying time is 5~8 minutes;

3) Decorative layer: Composite non-woven fabric or paper with 0.2-0.4mm sliced veneer, impregnated with melamine resin adhesive, the dipping amount is 70%-90%, the volatile content is 8%-15%, the pre-curing degree 40%~70%;

4) Wear-resistant layer: The wear-resistant layer is made of aluminum oxide wear-resistant paper impregnated with melamine resin adhesive, and the wear resistance is 6000~8000 revolutions after curing;

5) The substrate with the substrate adhesive layer made in step 2, the decorative layer after dipping and drying in step 3, and the wear-resistant layer in step 4 are contacted in sequence according to the substrate adhesive layer, decorative layer, and wear-resistant layer, using Hot press molding machine, at a temperature of 130~140°C, a pressure of 1.5~2.0MPa, and a time of 3~5 minutes, one-time molding.

The fast-growing wood veneers used for the substrate are: poplar, eucalyptus, willow, paulownia, birch, basswood, radiata pine, fire pine, longleaf pine, Douglas fir, and Pine genus wood sliced veneer, containing water The rate is 4%~8%, and the surface has no pollution, groove marks, live knots, dead knots and cracks.

The sliced veneer of the decorative layer is any one of oak, ash, oak, teak, birch, beech, maple, catalpa and black walnut.

The mass ratio of the melamine resin adhesive is 500:250:100:75:50:3 of formaldehyde: melamine: urea: water: polyethylene glycol 200: nano silicon dioxide.

The manufactured floor surface plate is composed of a substrate, a glue layer on the surface of the substrate, a decorative layer and a wear-resistant layer in sequence.

The manufacturing method of the floor surface plate of the present invention is scientific and reasonable, easy to shape and good in quality. The floor surface board of the present invention is formed by hot-pressing the fast-growing wood veneer coated with melamine resin as the substrate, veneer impregnated with melamine resin adhesive as the decorative layer, and aluminum oxide wear-resistant paper impregnated with melamine resin adhesive as the wear-resistant layer. Floor boards. The aluminum oxide wear-resistant paper is pasted on the surface of the thin wood layer impregnated with melamine to improve the wear resistance of the surface board. And it can achieve the wear resistance of laminate flooring. The advantages of saving wood resources and having the performance of a reinforced floor surface board can be taken into account at the same time.
