Description

  The present invention is an improvement of floor board material. More specifically, it does not cause cracking when nailing, and it can be applied to decorative sheets neatly, and it can be produced resource-saving using waste materials. The present invention relates to a wood plastic floor board material that can be removed.

  In general, a floor board material for a house or the like is produced by forming a protruding fruit and a matching groove on the side surface portion thereof, and for the laying of the floor board material, This is done by fitting the fruit and the groove and fitting each floor board material to a base material such as plywood.

  Conventionally, floor boards made of plywood obtained by laminating a plurality of wooden boards as described in <Patent Document 1> are well known.

  However, in the above-mentioned floor board material, since the joint portion is formed of a wooden board, the plywood sometimes breaks along the fiber direction due to an impact at the time of nailing.

  In addition, the floor board material made of such plywood is easy to break when the edge of the top surface of the board is chamfered, so the decorative sheet can not be adhered cleanly to the edge, and the appearance of the product is deteriorated. I was dissatisfied.

In addition, since the conventional floor board material uses raw wood such as conifers and hardwoods as a material for plywood, it has been a waste of resources due to mass production and cannot be said to be an environmentally friendly product.

  BEST MODE FOR CARRYING OUT THE INVENTION The best mode for carrying out the present invention will be described in more detail with reference to the drawings specifically shown as follows.

“Example 1”
A first embodiment of the present invention will be described with reference to FIGS. First, what is indicated by reference numeral 1 in the figure is a floor board substrate 1, and what is indicated by reference numeral 2 is a joining portion that joins the floor boards together. And what is indicated by reference numeral 3 is a decorative sheet made of synthetic resin.

  Next, the configuration of the present embodiment will be described. First, in this example, a high-toughness fiberboard produced by kneading and extrusion-molding a cellulosic powder and a thermoplastic binder resin was used for the floor board substrate 1 (see FIG. 1).

  For the floor board substrate 1, a high-toughness fiber board having a cellulose powder content of 60% by weight that is easy to mold and excellent in strength was used.

  At this time, the content of the cellulosic powder is preferably 50% by weight or more and less than 80% by weight from the viewpoint of moldability and toughness of the high toughness fiberboard.

  And as a cellulose-type powder contained in a high toughness fiber board, the wood powder which is a waste material inevitably generated in a woodworking factory etc. was used.

  The thermoplastic binder resin used for the high toughness fiberboard is polypropylene (PP), which has excellent processability and can be recycled.

  Furthermore, the joint part 2 which forms the fruit 21 and the groove 22 and joins the floor boards together is provided on each side of the floor board substrate 1 (see FIG. 2).

  In the floor board substrate 1, the lower part of the groove 22 of the joint 2 is formed so as to protrude outward from the upper part.

  As a result, when the floor board material is nailed to the underlaying material G at the time of laying, the nail N can be hit vertically in the extended portion of the lower part of the groove groove 22 in the floor board substrate 1, so that it is conventional. The floorboard material can be fixed more firmly than when nailing diagonally, and advanced nailing techniques are not required.

  In addition, the fruit 21 and the grooving groove 22 in the joint portion 2 have a shape with a margin in the fitted state to reduce the squeaking noise when walking on the floor board.

  And the abrasion-resistant resin sheet made from a polypropylene which exhibits a grain pattern or a marble pattern as the decorative sheet 3 was stuck on the surface of the floor board substrate 1.

  By comprising as mentioned above, the floor board material excellent in the functionality which combined the wood texture by a cellulose powder, and the high toughness by a thermoplastic binder resin was implement | achieved.

  And since the high toughness of the floor board substrate 1 also works on the fruit 21 and the groove 22 formed on each side of the floor board substrate, which is the joint 2 that joins the floor boards together, Even when the nail N is driven into the joint portion 2 of the floor board substrate 1 when laying on the floor board, the impact does not cause a crack in the floor board material.

  Further, since the edge of the upper surface of the floor board is not chamfered during chamfering unlike a floor board made of plywood, the fixing property of the decorative sheet 3 is good, and the decorative sheet 3 extends to the edge of the floor board substrate 1. Can be pasted neatly.

  In addition, the high toughness fiberboard used for the floor board substrate 1 can be produced using waste materials such as wood flour, and therefore can be produced resource-saving without wasting raw wood.

  Further, in this embodiment, the floor board 1 is provided with a plurality of hollow portions 11, 11,.

  When the hollow portions 11, 11,... Are formed on the floor board substrate 1, the size of the hollow parts 11 and the interval between the hollow parts are set so that the minimum strength as a floor board material can be maintained.

“Example 2”
Next, a second embodiment of the present invention will be described below. In the present embodiment, as the cellulose powder contained in the high-toughness fiber board of the floor board substrate 1, the brewed tea husk produced as a waste material in the food and beverage industry is used, and the thermoplastic binder resin has a very high strength and can be recycled. Possible high density polyethylene (HDPE) was adopted.

  This makes it possible not only to recycle the waste material but also to add antibacterial action to the tough fiberboard by the catechin component contained in the tea husk and to suppress the propagation of germs adhering to the floor and to obtain an excellent hygiene effect it can.

  Further, in this embodiment, the weight is reduced by arranging a plurality of grooves 12, 12,... At the lower part of the floor board substrate 1 (see FIG. 3).

“Example 3”
Next, a third embodiment of the present invention will be described with reference to FIG. In this embodiment, the truss-shaped hollow portions 11 and 11 are formed in the cross-sectional direction of the floor board substrate 1 so that the strength can be maintained (see FIG. 4).

  The present invention is generally configured as described above. However, the present invention is not limited to the illustrated embodiment, and various modifications can be made within the description of “the scope of claims for utility model registration”. For example, the cellulose powder used for the high-toughness fiber board of the floorboard substrate 1 may be rice husk or fruit husk powder as long as it is not wood powder or brewed tea husk, There is no problem even if the content is 90% by weight or more.

  Furthermore, the thermoplastic binder resin to be mixed with the material is not limited to polyolefin resin such as polypropylene (PP) or high density polyethylene (HDPE), but can be polyethylene terephthalate (polyethylene terephthalate) as long as it has a suitable strength and can be recycled. PET), ABS resin (ABS), or the like can be used, and any of the decorative sheets 3 can be selected as long as it is a recyclable resin.

  Further, the cross-sectional shape of the hollow portion 11 and the groove portion 12 of the high-toughness fiber board used for the floor board substrate 1 is not limited to a square shape or a truss shape, and may be a circular shape or a semicircular shape as shown in FIG. It belongs to the technical scope of the present invention.

  In recent years, deforestation that causes global warming and ecosystem disturbance has been seen as a problem on a global scale, and effective utilization of forest resources has become an essential issue in industry.

  Under such circumstances, the wood plastic floor board material of the present invention is an environmentally friendly technology that not only can reduce the waste of raw wood by using resin materials, but can also recycle wood powder and tea shells that are discarded as waste materials. Therefore, the demand in the market is large and its industrial utility value is very high.
