Therefore, the use of this wood waste has been studied for a long time, and there are already examples such as phenol boards, chipboards, hard fiberboards, and charcoal solid fuels.

まり重要な要因ではない。 The present invention is a novel method for utilizing this wood waste, particularly flaky wood chips such as planing shavings and chips, as a surface decoration forming material for any interior material including wall covering materials and floor finishing materials. The first step is to mix and stir thermoplastic synthetic resin pellets and thermoplastic synthetic resin paste into flaky wood pieces such as planer shavings.
The second step is to obtain a mixture in which the pellets are evenly adhered to the flaky wood using the adhesive strength of the paste, and the mixture is fed to an extruder to form a thick extruded sheet. The third step is the step of obtaining the thick sheet, the fourth step is the step of slicing this thick sheet to an appropriate thickness to obtain a thin top sheet, and the fifth step is the step of lining this top sheet with an appropriate backing material. This is a manufacturing method for interior materials using flaky wood, which consists of various steps, and an example of its implementation will be explained with reference to a drawing. Approximately 1 to 4 cm 2 in size is suitable, and items in this range are common.
It is not necessary to classify the material in particular, but if a dense surface pattern is required, it is best to coarsely grind the planer shavings etc. using a coarse grinder and remove the powder before using. The material of this flaky wood piece 1, that is, the type of wood, does not need to be particularly selected, but the closer the grain is, the better the surface pattern of the resulting interior material will be, but these will change depending on the extrusion conditions. It's not a very important factor.

出て象眼状の装飾効果が得られる。 The thermoplastic synthetic resin pellets 2 are thermoplastic synthetic resins such as vinyl chloride resin, copolymers mainly composed of vinyl chloride, ethylene copolymers such as EVA, acrylic ester resins, and thermoplastic polyurethane resins. Use alone or in combination. To enhance the pattern effect of the flaky wood piece 1,
These pellets 2 are colorless and transparent or translucent,
Alternatively, a colored and transparent one is suitable. When transparent pellets are used, all of the book pieces 1 located in the topsheet A can be seen through, resulting in a deep pattern effect. On the other hand, when opaque colored pellets are used, the outline of the wood piece 1 stands out clearly and an inlaid decorative effect is obtained.

次いでペレツト２を添加して全体を撹拌して木片
−ペレツト混和物を得る。 Uniform mixing of the wood flakes 1 and the synthetic resin pellets 2 is impossible because their physical shapes and properties are significantly different. When the two are simply mixed, the pellets 2 move to the bottom of the mixing tank, and the flaky wood pieces 1 move to the top and become separated. Therefore, in the method of the present invention, a paste such as vinyl chloride resin is used as a means for preventing separation of the two and obtaining a uniform mixed state. The vinyl chloride resin paste is a very viscous liquid substance that acts as a temporary glue between the wood flakes 1 and the pellets 2, and when heated and kneaded in an extruder, the synthetic resin that makes up the pellets 2 It is mixed in
It has excellent suitability as this type of binder. It is preferable to add the paste to the wood chips 1 before adding the pellets 2. The best method is to spray or spray the paste while stirring the wood piece 1 to evenly apply the paste to the wood piece 1.
Next, pellet 2 is added and the whole is stirred to obtain a wood chip-pellet mixture.

で木片−ペレツト混和物が分離したり目詰りを起
すことはない。 The amount of each material added is approximately 40 parts of wood chips per 100 parts of pellets, and the amount of paste is 10 to 100 parts by weight.
20 copies is suitable. Paste is vinyl chloride resin
Use a formulation in which approximately 50 parts of a plasticizer such as DOP is added to 100 parts. This mixing ratio should be arbitrarily set depending on the pattern. When you squeeze the resulting mixture with your hands, it will come together in a sticky consistency.
The best consistency is one that maintains its clump-like shape for a while, but eventually collapses. When the wood chip-pellet mixture obtained in this way is put into the hopper of an extruder, it is pushed into the screw part of the extruder by its own weight, but when it is put into the screw type hopper, it is pushed into the screw part of the extruder by its own weight. Although it is pushed in, a screw-type hopper is more suitable. These steps do not cause separation or clogging of the wood chip-pellet mixture.
押出機はベント式が適している。これは木片１

におけるブレーカープレートは除いておくことが
肝要であろう。 A vent type extruder is suitable. This is wood piece 1
This is because the moisture contained therein is vaporized by heating during extrusion, resulting in gas ejection. However, it should not be limited to only the vent type; even non-vent type types, in which gasified moisture bubbles are uniformly dispersed,
In some cases, it may even have a decorative effect. It may be important to exclude the breaker plate in the extruder.
押出機における押出シートの押出厚さは概ね５
〜10mm厚さを目処に行い、これは余り厚いとシー
ト中に巨大な泡が入つたり、木片１に偏りが生じ

〜１ｍ位が適している。 The extrusion thickness of the extruded sheet in the extruder is approximately 5
Aim for a thickness of ~10mm; if it's too thick, huge bubbles will form in the sheet or the wood pieces 1 will be uneven, while if it's too thin, the T-die will become clogged. The wood piece 1 will be fragmented and its decorative effect will be reduced. Therefore, the thickness of the extruded sheet during extrusion should be determined by taking these conditions into consideration. The width of the extruded sheet should be determined arbitrarily, but it is generally the same as the normal width of the interior material, for example 90 cm.
~1m is suitable.

実用上有効な手段である。 Such extruded sheets can be used for rugs, table tops, etc. even in their raw state, but in order to enhance the texture and pattern effect of the wood flakes 1, this thick extruded sheet is sliced in the thickness direction and used as a top sheet. It is most suitable to use A and a backing material B having a different hue by laminating the backing material B by any method or means. At the same time, since this extruded sheet has relatively severe unevenness on both the upper and lower surfaces, it is a practically effective means to remove the uneven surfaces by slicing to create a smooth surface.
表面シートＡのスライス厚さは用途に応じて任
意に設定されるべきであるが、概ね0.5mm〜1.0

ペレツト２を使用した時に木片１の数が多くな
り、うるさい感じになつたりするので上記の範囲
に止めるべきであろう。 The slice thickness of the top sheet A should be set arbitrarily depending on the application, but it is generally 0.5 mm to 1.0 mm.
A thickness of about 2.0 mm or 2.0 mm is suitable. If it is made too thin, the texture of the wood pieces 1 will be lost and only a flimsy decorative effect will be obtained; on the other hand, if it is too thick, the number of pieces of wood 1 will increase, especially when transparent pellets 2 are used, making it look noisy. Therefore, it should be kept within the above range.

This is laminated on the back surface of the topsheet A by lamination embossing or the like. When the product obtained by the method of the present invention is intended to be used as a floor finishing material, in terms of walking feel, soundproofing properties, and weight, it is
It is most suitable to use a sheet highly filled with wood flour as shown in No. 52457. This highly-filled wood flour sheet has a large number of flat air bubbles created by the moisture contained in the wood flour inside the sheet made of synthetic resin, and the wood flour itself is 50% of the compound weight. % or more, it is extremely effective as a backing material for floor finishing materials, and when combined with the top sheet A, which is made by slicing an extruded thick sheet as described above, it creates a structure in which all layers are made of wood waste. Therefore, an extremely useful floor finishing material that meets the policy of Japan can be obtained.

It is optional whether the upper surface is made uneven or smooth, and it is also possible to form a transparent coating layer as appropriate.
