Abstract

A wooden board comprising a plate-like base of wood material, a film coating attached to its surface. The surface veneer of the wooden board (4) is wood-plastic composite or plastic (2), a non-woven fabric (5a) coated with a film coating (1 ) being attached to its surface.

Description

A coated wooden board, a method for its manufacture, and its use
The invention relates to a wooden board according to the preamble of the appended claim 1 , comprising a plate-like base with a film coating attached to its surface. The invention also relates to a method for manufacturing said coated wooden board according to the preamble of the appended claim 7. The invention further relates to the use of a coated wooden board.
It is known to coat wood-based boards, such as plywood, with various coatings to improve their surface properties; for example, wear resistance and moisture resistance can be improved. Coated wood- based boards can be used, for example, as walls for concrete casting moulds, as wall and floor material for various cargo spaces in the transportation equipment industry, and for other purposes.
In general, the materials used for coating wooden boards, such as plywood, are coating films to be pressed onto the surface of the wood, such as phenolic film and other papers impregnated with resin. The coating can be cured by hot pressing to form a relatively rigid glossy film on the surface of the wooden board. Such a coating is used to diminish the absorption of water into the wood material, but the coating is still not completely waterproof. When water is absorbed through the film into the wood material, it causes uneven swelling of the fibres in the wood material, which is seen as a harmful rippling effect; that is, a wave-like surface is formed for the product. When such a wooden board is used, for example, in a concrete casting mould, this uneven swelling of the surface is reflected in the concrete casting surface and causes a visual disadvantage and extra work.
It is an aim of the present invention to disclose a coated wooden board structure for improving the surface properties of a film-coated wooden board, for reducing or eliminating the swelling and waving of the wood material caused e.g. by water, and also for improving the wear resistance of the wooden board. To achieve this aim, the wooden board according to the invention is primarily characterized in that the surface veneer of the wooden board consists of wood-plastic composite or plastic with a coated non-woven fabric attached to its surface.
The invention is based on the idea that wood-plastic composite or plastic can be used as a surface veneer for a wooden board, when a non-woven fabric is attached to the surface of the wood-plastic composite or plastic, enabling the coating of the wood-plastic composite or plastic further with various coatings. The non-woven fabric attached to one side of the wood-plastic composite or plastic, in turn, enables the attachment of the wood-plastic composite or plastic to a plate-like base of a wooden material.
In this context, wood-plastic composite refers to a mixture of wood and plastic, in which the wood material is in the form of fibres or powder blended with plastic. Coating refers to such a coating that can be cured by hot pressing to form a so-called film coating on the surface of the board. Non-woven fabric refers, in this context, to a non-woven fabric, mat or felt consisting of fibres. The non-woven fabric may also be paper or other thin material consisting of fibres.
The wooden board structure according to the invention, in which the wood-plastic composite or plastic forms a part of the base structure of the wooden board, can be used to improve or to overcome many disadvantages of wood veneer as the surface veneer for the wooden board, including, for example, changes due to moisture, as well as cracking and scaling upon nailing. Furthermore, the wear resistance is better with the wooden board structure according to the invention.
The method according to the invention, in turn, is primarily characterized in what will be presented in the characterizing part of the independent claim 7. The use of a wooden board according to the invention, in turn, is characterized in that the wooden board is used as the surface that comes into contact with cast concrete in a concrete casting mould. In the following, the invention will be described in more detail with reference to the appended Fig. 1 which shows, in a cross-sectional view, the structure of a wooden board according to the invention.
Figure 1 shows the structure of a wooden board that consists of a plate-like base 4 of wood material and wood-plastic composite or plastic 2 on top of it, wherein a non-woven fabric 5a is attached to its upper surface and is further coated with a film coating 1. A non-woven fabric 5b is attached to the lower surface of the wood-plastic composite or plastic 2 and is attached to the wooden board by means of an adhesive layer 3.
The wooden board 4, onto whose surface the wood-plastic composite or plastic 2 is attached by means of the non-woven fabric 5b and the adhesive layer 3, is, for example, a plywood board composed of several wood veneer layers attached on top of each other. The wooden board may also consist of another wood-based material, such as, for example, particle board, fibreboard or other material containing wood- based parts bonded together.
The wood-plastic composite used as the surface veneer is a mixture of wood and plastic, in which the wooden material is in the form of fibres or powder blended with plastic. The plastic used in the blend is, for example, a polyolefin. The wood content in the mixture does not exceed 60%. The thickness of the wood-plastic composite or plastic attached to the surface of the wooden board is normally 0.2 to 2.0 mm. The thickness of the wood-plastic composite is preferably 1 to 2 mm, wherein e.g. the cracking of the board upon nailing can be reduced in teh best way. If whole plastic is used instead of wood-plastic composite as the surface veneer, its thickness is preferably about 0.5 mm. The non-woven fabric is attached to the surface of the wood-plastic composite or plastic in connection with its manufacture, wherein it is partly inside the wood-plastic composite or plastic.
The method for manufacturing the wooden board structure according to the invention comprises the coating of a non-woven fabric 5a attached to the upper surface of the wood-plastic composite or plastic 2, with a suitable coating 1 , depending on the use of the board to be made; and the fixing of the wood-plastic composite or plastic 2 to the wooden board 4 by means of a non-woven fabric 5b and adhesive layer 3 on the lower surface of the wood-plastic composite or plastic.
For coating the wood-plastic composite or plastic 2, it is possible to use common film coating methods, thanks to the non-woven fabric attached to the surface of the wood-plastic composite or plastic 2. Thus, a coating 1 that is, for example, phenolic, melamine, urea, or epoxy resin based, is hot-pressed onto the surface of the non-woven fabric 5a attached to the wood-plastic composite or plastic 2. The coating 1 is impregnated in paper or in fluid form when it is applied onto the surface of the non-woven fabric 5a attached to the wood-plastic composite or plastic 2, after which the curable resin contained in the coating is pressed onto the surface of the board by applying heat and pressure. In connection with the hot-pressing, the coating surface 1 can also be embossed with an anti-slip pattern to improve substantially the friction properties of the surface.
The non-woven fabric 5b on the lower surface of the wood-plastic composite or plastic 2 makes it possible to glue the wood-plastic composite or plastic 2 to the wooden board 4. For the glueing, a known reactive adhesive is used that is generally curable by heat. Examples to be mentioned include phenolic resins, polyester resins, epoxy resins, and melamine resins.
In the following, surface properties of the wooden board according to the invention will be presented in comparison with existing products.
A test specimen according to the invention was made, in which the surface veneer 2 used was wood-plastic composite consisting of a blend of polypropylene and wood powder. The content of wood powder in the mixture was about 40%. The thickness of the wood-plastic composite was 1.6 mm. Further, a film coating 1 was hot-pressed onto a non-woven fabric 5a attached to the upper surface of the wood- plastic composite 2. Phenolic film (80/220 g) was used as the coating 1 in the test specimen. The properties of the wooden board according to the invention were compared with those of a conventional wooden board structure, in which the wooden board 4 was coated with a phenolic film 1 , wherein wood was used as the surface veneer. A second reference was a wooden board 4, whose surface was provided with a wood-plastic composite 2 by means of an adhesive layer 3 and a non-woven fabric 5b, but the wood-plastic composite 2 was not coated further; in other words, the wood-plastic composite was used in this case as the coating itself. Furthermore, birch plywood with an untreated surface was used as a reference. The results are presented in the table below.
Figure imgf000006_0001
Compared to a conventional wooden board with a phenolic film surface, the wooden board structure according to the invention, comprising wood-plastic composite coated with a phenolic film, has significantly better impact resistance and Shore D hardness exceeding 10%, but no differences are found in the resistance to scratching. Furthermore, no rippling effect is observed in the wooden board according to the invention; in other words, no wave-like surface is formed in the product, and the product does not crack upon nailing. When the wood-plastic composite coated with a phenolic film was compared with a wooden board coated with wood-plastic composite, it was found that the impact resistance of the products is in the same order, but the structure according to the invention has a significantly better resistance to scratching, and the Shore D hardness exceeds 15%. The wood-plastic composite is exposed when the film coating wears out, wherein the Taber (wearing of the film surface) of the board structure according to the invention is in the same order as that of a conventional film-coated wooden board, about 850 r.
It can be seen from the results that when wood-plastic composite provided with a film coating is used as surface veneer for a wooden board, it is possible to eliminate swelling and waving caused by water and to improve the impact resistance of the board, compared with the use of wood veneer as the surface veneer.
The above-described wooden board according to the invention is used, among other things, in concrete casting as the surface that limits the mould cavity, i.e. as the concrete casting board, wherein the surface film 1 comes into contact with concrete. The aim is that the film-coated wood-plastic composite or plastic on the surface of the board improves the wear resistance of the wooden board and thereby increases the number of uses of the concrete casting boards.
The wooden board according to the invention can also be applied to other uses, in which the film-coated wood-plastic composite or plastic forms a wear surface, for example the floor in the load space of a vehicle, and the invention is thus not intended to be limited to the embodiment presented above as an example.
