Description

A DECKING BOARD AND A METHOD AND A SYSTEM FOR MANUFACTURING A DECKING BOARD
Field of the Invention
This invention relates to a decking board. This invention further relates to a method and a system for manufacturing a decking board.
Background of the Invention
A decking board is an element that may be used, for example, for terraces, rooms and ceilings. The decking boards may consist of wood material. They may comprise, for example, pre-cut timber materials. It is also possible to manufacture decking boards that comprise plastic as a raw material.
However, there is still a need for a new decking board and for a method and a system for manufacturing a decking board.
Summary of the Invention
The present invention discloses a novel decking board. In addition, the present invention discloses a solution for manufacturing a decking board.
The structure of the decking board having, among other things, large radii of curvature of the corners of a second side of the decking board may have very good strength properties. This effect can be increased if also corners of a first side have large radii of curvature.
The inventors of the present invention have surprisingly found a way to manufacture a novel decking board. Due to the structure of the novel decking board, it is possible, among other things, to increase the strength properties of the manufactured decking board and/or production efficiency of the decking board even while using recycled material as a raw material.
The amount of the recycled raw materials may need to be increased due to environmental reasons. However, it has been observed that strength properties of a manufactured decking board may be decreased along with an addition of recycled materials, such as recycled fibers and fillers. Due to the good strength properties of the novel decking board, it is possible to use more recycled material as a raw material than with conventional decking boards, i.e. the novel product may be more environmentally friendly than conventional decking boards. Thus, according to an advantageous embodiment of the invention, the decking board comprises recycled cellulose fibers and recycled plastic polymers. In addition, it is possible to add oval holes into the structure of the decking board in order to decrease the weight of the product.
According to an advantageous embodiment of the invention, the raw material of the decking board comprises adhesive label waste material. In addition, the decking board may comprise at least one kind of virgin polymer, such as polyolefin, preferably polypropylene. In the method for manufacturing a decking board, used raw materials are preferably treated in an extruder in order to form the new decking board.
The decking board has preferably only one installation side, i.e. the decking board is not symmetrical in the vertical direction, but, on the contrary, a second side of the decking board and a first side of the decking board differ from each other.
The new decking board and/or the manufacturing process may make it possible
- to manufacture the decking board more efficiently,
- to manufacture the decking board mainly from recycled materials,
- to manufacture the decking board with good runnability,
- to manufacture a decking board not containing any harmful chemicals,
- to manufacture an environmentally friend decking board,
- to manufacture the decking board without any PVC,
- to manufacture a fully recyclable decking board; for example, the manufactured decking board may be recycled or re-ground and converted to a new product; - to install the manufactured decking board with conventional woodworking tools,
- to fasten the decking board with known fastening members,
- to show a good solution for waste off-cuts and trimmings from self- adhesive labels.
Aspects of the invention are characterized by what is stated in the independent claims 1 , 17, 18 and 19. Various embodiments of the invention are disclosed in the dependent claims.

R3 radius of curvature of the groove 12 on the first side.
The decking board is preferably a part of a floor, most preferably a part of a terrace floor. The decking board may also be a part of a ceiling or a wall. The terms "first side 3" and "first surface 3" refer to a side that is in view when the decking board is installed, i.e. an installation side of a decking board 1 . If the decking board (when installed) is part of a floor (such as a terrace), the first side 3 is a top side of the decking board 1 . The term "corner of the first side" refers to a corner of the first side of the decking board. If the decking board is part of a floor, the corner of the first side is an upper corner of the decking board.
The terms "second side 2" and "second surface 2" refer to a side that is not usually in view when the decking board is installed. If the decking board (when installed) is a part of a floor (such as a terrace), the second side 2 is a bottom side of the decking board 1 .
The term "corner of the second side" refers to a corner of the second side of the decking board. If the decking board is part of a floor, the corner of the second side is a bottom corner of the decking board.
The decking board has a first side 3, also called as an installation side, and a second side 2. The first side 3 has preferably good strength properties without appearance defects. The second side 2 has preferably a structure that is compatible with a fastening member 20 of the decking board 1 in order to achieve good fastening of the decking board. Therefore, there are advantageously different structures on the first side 3 and the second side 2 of the decking board 1 . The decking board 1 is preferably symmetrical in the width direction 15, i.e. the first transversal side FS of the decking board is preferably substantially a mirror image of the second transversal side SS of the decking board. Therefore, the properties of the decking board 1 presented in this application relate to both sides, i.e. to the first transversal side and to the second transversal side. In other words, for example the properties of a corner of the second side presented in this application relate to both corners of the second side, i.e. the corners of the first transversal side FS and the second transversal side SS of the decking board. Similarly, the properties of a corner of the first side presented in this application relate to both corners of the first side, i.e. the corners of the first transversal side FS and the second transversal side SS of the decking board 1 . The corners of the first transversal side FS and the area between them preferably form a groove 22. Similarly, the corners of the second transversal side SS and the area between them preferably form a groove 23.
The width 15 of the decking board is preferably at least 100 mm, more preferably the width 15 is between 100 and 140 mm. According to an advantageous embodiment of the invention the width 15 of the decking board is approximately 120 mm.
The height 14 of the decking board 1 is preferably at least 15 mm, more preferably at least 20 mm or at least 25 mm. In addition, the height of the decking board is preferably 50 mm at the most or 40 mm at the most, more preferably 35 mm at the most or 30 mm at the most. According to an advantageous embodiment of the invention, the height 14 of the decking board is between 25 and 31 mm, for example 28 mm.
The weight of the decking board 1 is preferably between 650 and 830 kg/m3, more preferably between 680 and 800 kg/m3. According to an advantageous embodiment, the decking board 1 is manufactured in such a way that the weight of the decking board is between 2.2 and 2.8 kg/m, preferably between 2.3 and 2.7 kg/m.
The decking board 1 may comprise oval holes 1 1 . The decking board 1 has preferably at least two oval holes 1 1 , more preferably at least three oval holes 1 1 . The number of the oval holes may be, for example, between 2 and 6 or between 3 and 5. According to an advantageous embodiment, the decking board comprises three oval holes 1 1 . The weight of the product 1 and the amount of the needed raw material decrease due to the holes 1 1 . Thanks to the decreased weight of the decking board 1 , the installation of the decking boards 1 may be easier and, moreover, the transportation of said decking boards 1 may be cheaper than with conventional decking boards, which do not comprises any kind of holes. However, not only oval shaped holes, but also holes of other shape may be used in the decking board. Holes of other shape may comprise, for example, symmetrically rounded (circled) holes or tetragon shaped holes, such as square shaped holes. Even these kinds of holes will cause decreased weight of the product, typically even more than the oval shaped holes, and, hence, decrease the transportation costs. Even so, the oval holes are preferably used in the invention, because the strength of the decking board 1 comprising oval holes 1 1 may be much better than the strength of a decking board comprising tetragon shaped holes, and even better than the strength of a decking board comprising symmetrically rounded (circled) holes. In other words, the shape of the oval hole 1 1 is better than a shape of many other kinds of holes in order to achieve better strength properties. Moreover, the oval holes 1 1 may increase the production efficiency by increasing the runnability of the manufacturing process, because the oval shaped holes may be used in order to achieve small friction during the manufacturing process. However, there should not be too many oval holes 1 1 in the decking board because too many oval holes 1 1 may decrease the strength properties of the decking board 1 . This should be considered at least when the amount of the used recycled raw material is at least 70%. In addition, if a mould is used in the manufacturing process, there probably should not be too many holes in the decking board 1 . A first distance 8 between an oval hole 1 1 and the second side 2 of the decking board is preferably substantially the same as the second distance 9, i.e. the first distance 8 differs from the second distance 9 preferably 20% at the most (i.e. between 0.8 and 1 .2), more preferably 15% at the most. In addition, the second distance 9 between two oval holes 1 1 is preferably substantially the same as a third distance 18 between an oval hole 1 1 and a surface 3 of the decking board. In other words, the difference between the second distance 9 and the third distance 18 is preferably 20% at the most (i.e. between 0.8 and 1 .2), preferably 15% at the most. In addition, due to the above mentioned ratio, it is possible to manufacture better board decks comprising lots of fillers and recycled fibers. According to an advantageous embodiment of the invention, the first distance 8, the second distance 9 and the third distance 18 are between 3 and 10 mm, preferably between 4 and 7 mm.
Shapes and dimensions of the oval holes are preferably selected in such a way that it is possible to achieve very good runnability properties for the decking board to be manufactured. The width 16 of the oval hole 1 1 is preferably about 25 mm, for example between 20 and 30 mm. The height 17 of the oval hole 1 1 is predetermined in such a way that the third distance 18 between the oval hole 1 1 and the first side 3 and the first distance 8 between an oval hole 1 1 and a second side 2 are both at least 3 mm, more preferably between 5 and 7 mm. According to an advantageous embodiment of the invention, the height 17 of the oval hole 1 1 is approximately 16 mm, for example between 14 and 18 mm.
The height 10 of the corner of the second side 5 of the decking board 1 is preferably between 5 and 7 mm. According to an advantageous embodiment of the invention, the height 10 of the corner of the second side 5 is approximately 6 mm. A length of the corner of the second side 5, i.e. the length of the inner surface 5b of the corner of the second side (shown in fig. 8), is preferably at least 5 mm or at least 6 mm, more preferably at least 8 mm or 10 mm. The length of corner of the second side 5 (i.e. the inner surface 5b of the corner of the second side, is preferably 25 mm at the most or 20 mm at the most, more preferably 15 mm at the most or 12 mm at the most. The radius of the curvature R1 a, R1 b of the corner of the second side 5 is preferably limited by the height 10 of the corner of the second side 5 and/or a space needed for fastening means 20 used for the fastening of the decking boards 1 . The radii of the curvature (R1 a, R1 b) of the corner of the second side 5 are preferably both between 0.5 * height 10 of the corner of the second side and 0.25 * height 10 of the corner of the second side. The radii of curvature (R1 a, R1 b) of the corner of the second side 5 may be, for example, between 0.8 and 1 .2 times 0.4 times the height 10 of the corner of the second side, i.e. between 0.32 and 0.48 times the height 10 of the corner of the second side. According to an advantageous embodiment of the invention, the radius of the curvature (R1 a, R1 b) of the corner of the second side 5 is between 1 .5 and 3 mm. According to an advantageous embodiment of the invention, the structure of the corner of the second side 5 is such that a fastening member 20, preferably a so called T-clip manufactured by UPM Corporation, can be used with the new decking board 1 . There may also be, for example, only one radius of curvature R1 of the corner of the second side. Despite the number of the radii of the curvature R1 of the corner of the second side, the above mentioned definition may be used for the radius of curvature of the corner of the second side.
A radius of curvature R2 of the corner of the first side 4 is preferably quite large in order to increase the runnability of the manufacturing process. The radius of curvature R2 is usually limited by the height 13 of the corner of the first side 4, i.e. the radius of curvature R2 of the corner of the first side 4 is preferably 0.6 or 0.5 times the height 13 of the corner of the first side at the most. The large radius of the curvature R2 also increases the strength properties of the decking board 1 . The strength properties may be important because, in the end use, there may be, among other things, quite heavy furniture and, in addition, persons with high-heeled shoes walking on the decking board 1 . The radius of curvature R2 of the corner of the first side 4 is advantageously at least the same as the radius of curvature R1 , R1 a, R1 b of the corner of the second side 5, more preferably R2 > R1 . According to an advantageous embodiment of the invention, the radius of curvature R2 of the corner of the first side 4 is between 3 and 5 mm. There may be also, for example, two radii of curvature R2 of the corner of the first side. Despite the number of the radii of curvature R2 of the corner of the first side, the above mentioned definition may be used for the radius of curvature of the corner of the second side. Usually, the larger the radii of curvature R1 of the corner of the second side 5 and the radii of curvature R2 of the corner of the first side 4 are, the better is the runnability of the manufacturing machine and, hence, the more efficiently the decking board 1 may be manufactured. The decking board 1 may have a supporting structure 7 within the corner of the first side 4. Thanks to the supporting structure 7, the strength of the corner of the first side 4 of the decking board 1 and, therefore, the strength of the whole decking board 1 may be substantially increased. In addition, the runnability of the manufacturing process may be increased thanks to the supporting structure 7.
The supporting structure 7 of the corner of the first side 4 extends to a first end point 25 of the supporting structure 7, which is preferably at least 6 mm above of the inner surface 5b of the corner of the second side 5, more preferably at least 7 mm or at least 8 mm above of the inner surface 5b of the corner of the second side 5. The supporting structure 7 of the corner of the first side 4 extends from the first end point 25 of the supporting structure 7 to the second end point 26 of the supporting structure, which second point 26 is at the inner side of the corner of the first side. The length 27 of the supporting structure 7 is preferably at least 8 mm, more preferably between 8 and 10 mm. Thanks to the above mentioned dimensions, the strength properties of the decking board may be increased. Moreover, a fastening member 20 may be used in order to fasten the manufactured decking board. The fastening member 20 may need a space of about 5 mm above the corner of the second side. There may also be some thermal expansion in the decking board that need to be taken into account.
The first side 3 of the decking board 1 has preferably many very tiny grooves 12 in order to achieve high-friction surface. The width 19a between the grooves 12 may be between 5 and 20 mm, more preferably between 10 and 14 mm. The height 19b of the groove 12 on the first side 3 may be between 1 and 2 mm. A radius of curvature R3 of the groove 12 is preferably between 1 and 2 mm. Thanks to the tiny grooves 12, the friction of the first side 3 of the decking board 1 may be increased resulting in good anti-slip properties even when the first side 3 is wet. Moreover, the first side 3 may be easy to clean due to the very tiny size and rounded corners of the grooves.
The second side 2 of the decking board 1 has preferably some grooves 6. The grooves 6 are added to the second side 2 in order to prevent possible problems caused by drying shrinkage. Due to the grooves 6, a blistering effect may be prevented. The grooves 6 are preferably small in size. The height 21 of the grooves 6 is preferably between 0.2 and 3.0 mm or between
0.5 and 2.0 mm. The amount of the grooves 6 on the second side 2 is preferably one less than the amount of the oval holes 1 1 in the decking board
1 . For example, if there are three oval holes 1 1 in the decking board 1 , there are preferably two grooves 6 on the second side 2 of the decking board 1 .
The grooves 6 on the second side are preferably placed at a location which is between the oval holes 1 1 in the vertical direction of the decking board 1 in such a way that there is always one groove 6 on the second side of the decking board at a location which is between the holes 1 1 in the vertical direction of the decking board 1 . This can also be seen in the Figure 5. According to an advantageous embodiment of the invention, a distance between two grooves 6 is between 38 and 50 mm, preferably between 42 and 46 mm. The decking board 1 is advantageously cellulose fiber plastic composite, for example, wood plastic composite. Cellulose fibers used in this invention can come from any plant material that contains cellulose, for example wood material. The wood material can be from softwood trees, such as spruce, pine, fir, larch, douglas-fir or hemlock, or from hardwood trees, such as birch, aspen, poplar, alder, eucalyptus or acacia, or from a mixture of softwoods and hardwoods. Non-wood material can be from agricultural residues, grasses or other plant substances such as straw, leaves, bark, seeds, hulls, flowers, vegetables or fruits from cotton, corn, wheat, oat, rye, barley, rice, flax, hemp, manila hemp, sisal hemp, jute, ramie, kenaf, bagasse, bamboo or reed. The decking board advantageously comprises 20 - 60 w-% cellulose fibers, preferably 20- 50 w-% cellulose fibers. According to the invention, the cellulose fibers used for the decking board comprise at least 60 % chemically treated cellulose fibers (i.e. lignin free cellulose fibers), preferably the fibers used for the decking board comprise at least 70 % or at least 80 %, preferably at least 90 % or at least 95 % chemically treated lignin free cellulose fibers.
In addition, the decking board advantageously comprises from 20 to 80 w-% plastic polymers, preferably from 20 to 60 w-%. The plastic polymer may be virgin or recycled. The amount of the added plastic polymer, such as polypropylene, depends on the other raw material used. For example, if recycled material is used, the amount of added polymer depends on the amount of the different raw materials coming along the recycled material. The decking board 1 preferably comprises at least 70 w-% recycled raw material and, for example, the only added not recycled plastic may be polypropylene. Additionally the decking board may comprise fillers. The decking board 1 may also comprise other compounds, such as colours and waxes.
The recycled raw material comprises preferably paper and plastic, most preferably the recycled material comprises paper and plastic polymers which fall as surplus in self-adhesive label production. The proportion of the recycled paper and recycled plastic may vary depending on the product application.
The recycled label material may comprise surplus paper and plastic left over from the production of self-adhesive label materials. In an embodiment, the adhesive label laminate waste originates from adhesive label laminate production, which primarily produces production reject waste, edge cuttings from rolls and roll ends; from adhesive label laminate printing stations, producing primarily roll ends and label material left over from the die cutting of stickers and labels as well as reject; and/or from the end user clients of the adhesive label laminate, who paste the printed stickers and labels or the like onto their products. The waste coming from the end users is primarily release material, roll ends, and waste from the finished product. The adhesive label laminate waste is typically formed of label material, an adhesive layer, and release material. The liner of the label is usually a paper having a silicone coating or a plastic coating. The plastic polymer is preferably polypropylene. The plastic polymer may also be PVC, polyethylene, polypropylene, polystyrene or polyester.
The amount of the adhesive label laminate waste in the decking board 1 is preferably between 50-85 w-%. The adhesive label laminate waste may comprise, for example, adhesives 0 - 5 w-% or 1 - 4 w-% silicone 0-10 w-% or 1 - 9 w-%, cellulose fibers 20-100 w-%, and polymers 0-100 w-% or 5 - 95 w-%. The amount of additionally dosed plastic polymers is advantageously 15-50 w-% from the decking board 1 . Inorganic fillers may be added in order to increase the stiffness properties of the product. The amount of the fillers in the decking board is preferably between 0 and 25 w-%. The fillers preferably consist mostly of talc and/or calcium carbonate and/or fly ash and/or mica and/or glass-filler (i.e. at least 50 w-% from the fillers). The decking board may be coloured, for example, by using pigments. Therefore, the decking board 1 may comprise colours.
The manufactured decking board is preferably a wood plastic composite, for example a paper plastic composite. The decking board 1 may be manufactured, for example, by extrusion or by injection moulding process. Advantageously the decking board 1 is manufactured in an extrusion process using an extruder.
A person skilled in the art readily understands different embodiments of the invention. Therefore, it is obvious that the present invention is not limited solely to the above-presented embodiments, but it can be modified within the scope of the appended claims.
