ものである。Therefore, when molding a resin material that contains a large amount of mixed materials, it is necessary to clearly recognize the molding characteristics of the resin itself as well as the effects of the mixed materials during molding, and respond promptly. It is particularly important to selectively use molding techniques that are The problem of mixing of different materials that cause
This is a particular problem when the mixed foreign material, such as wood powder, has a lot of frictional resistance during flow, is not compatible with the resin material, and also generates a large amount of moisture or wood acid gas in the molding machine. This required special ingenuity in the molding method.

成形品の提供を試みたものである。The present invention combines the advantages of wood and synthetic resin materials, in response to the strong demand for new materials and effectively resolving the inconveniences of wood molded products and synthetic resin molded products in recent years. This is an attempt to provide a composite plate molded product that is inexpensive and has high utility value.

量産提供を特に可能としたものである。In particular, in the present invention, wood flour, which is a dissimilar material incorporated into the resin material, is subjected to various processing so that the characteristics of the mixed wood flour are matched under certain conditions, and open mold extrusion is performed during molding. Prepare a device and a heat roll device,
This eliminates the extrusion frictional resistance peculiar to mixed wood flour during molding and effectively removes generated debris, making it especially possible to mass produce wood composite boards.

担な木質合成板の提供を可能としたものである。In addition, in the present invention, since the extruded dough to be formed is first made into a plate shape with a predetermined thickness in a hot roll device, the composite board to be formed is warped and has some problems before being expanded or contracted. No defects were observed during the process, making it possible to provide wood composite boards with the desired thickness and flatness.

性の合口的々な奏効を期すべく、特にその構成の要旨を
粒径な８０〜３００メツシユ。The method for forming a wood composite board according to the present invention is particularly focused on the particle size of 80 to 300 mesh in order to achieve various effects on the wood properties described above.

具体的な実施例と、これ等の実施例に附随する相当の設
計変更を予定したものである。Wood flour with a moisture content of 1 to 5% is made into a thermoplastic resin material.
~70% of the mixture is heated and extruded to the front of the hot forming roll using a kneading screw.
Based on the point that this extruded dough is rolled to a predetermined thickness using the heated rolls without heating, the following specific examples and considerable design changes accompanying these examples are described. It was planned.
以下、本発明に係る木質合成板の典型的な成形力法にら

を破砕して同様の木粉（１）゛を得ることが予定された
ものである。Below, a typical forming force method for the wood composite board according to the present invention will be explained. (1) is wood powder obtained by heating and crushing wood, and its particle size is 80 to It is a mesh with a moisture content of 1 to 5%, and is usually prepared as pure wood flour, or it is prepared by adding urea resin adhesive (2) to wood chips etc. and curing it by heating. Afterwards, it was planned to crush this to obtain similar wood powder (1).
か−る木材粉の粒径並びに含有木分績の特定は樹脂成形
に際しての以下の諸理由によるものである。即ち、骨材

れによって成形機内壁面の腐蝕、グイ、成形型等の損耗
がもたらされ、又成形品自体の表面の荒れ、気泡、巣の
発生等の不都合をもたらしたものである。The particle size and wood content of the wood powder are specified for the following reasons during resin molding. In other words, when the wood flour as an aggregate has a moisture content within the usual range, when the wood flour is charged into a molding machine together with resin and heated, a larger amount of water vapor and wood acid gas is produced than the mixed wood flour. This causes corrosion of the inner wall surface of the molding machine, wear and tear of the mold, etc., and also causes problems such as roughening of the surface of the molded product itself, and the formation of bubbles and cavities.

分な加熱処理を施し、含有木酸を極力揮散せしめるよう
になすと共に、樹脂成形に際して更に木酸がガス化に伴
って蒸散することのないように含有水分の除去をなした
ものである。In order to avoid such inconveniences, sufficient heat treatment is applied during the molding of the wood powder to volatilize as much of the wood acid contained therein as possible, and at the same time, during resin molding, the wood acid evaporates as a result of gasification. The moisture content has been removed to prevent this from occurring.

必要な滑性を付与したものである。In addition, the use of the urea-based resin adhesive (2) in the description creates a hardened layer of the adhesive (2) on the surface of the wood powder (1) to be molded, and removes the moisture released during the heat treatment. This prevents wood from infiltrating into the molded wood powder again, neutralizes the wood acid during heat curing, and further imparts the necessary lubricity to the molded wood powder after curing.
尚、この木粉に於ける滑性の問題は、素材相互の混合に

の回避を期したものである。The problem with the slipperiness of wood flour has mainly been related to good kneading during mixing of the materials, compatibility of the materials with each other during molding, and extrusion resistance during molding. By specifically setting the particle size of the mixed wood flour (1) to 80 to 300 mesh, these problems can be avoided.

にしたものである。The thermal insulation heating during the formation of the forming roll (14) is due to the fact that a large amount of wood flour (1), which is a different material, is included in the resin material as the forming aggregate,
If the dough m lacks a sufficient heat storage state, the peripheral parts of the extruded dough will harden rapidly, and only the central part will be drawn into the rolls (14) to a large extent, making it difficult to roll and forming the dough. This causes wrinkles in the fabric, and also causes irregularities in the structure of the molded product, causing deformations such as warping and distortion. In order to avoid such inconveniences during forming, the raw #1m extruded from devices a and a' is not sufficiently kept warm and heated by the guide (13) 2 and the roll (14). This allows for precise molding.

のである。The method for forming a wood composite board according to the present invention is expected to achieve specific effects on the above-mentioned properties due to the characteristic structure described above. When a large amount of wood flour is mixed in, the extrusion device becomes strained, resulting in failure of extrusion, wear of the extrusion screw, or breakage of the forming tie. Therefore, it was necessary to reduce the extrusion pressure as much as possible and perform a gentle extrusion operation, but such a method is not only unsuitable for mass production molding, but also requires cooling the dough before molding, resulting in This is due to variations in the quality of E-products. The present invention is specifically disclosed to avoid such inconveniences, and by extruding the forming dough from a cylinder in front of the forming roll without passing through a die, the extrusion resistance in the extrusion device is reduced as much as possible. This eliminates the possibility of equipment wear and tear, tie breakage, etc., and at the same time enables mass production molding by reliable extrusion in large quantities. Moreover, there is no problem of cooling the extruded dough m, and variations in quality in the formed plate materials are also eliminated.

First, the company promises to provide high-quality board or panel materials.
