Description

Synthetic wood deck impregnated with fiber and resin, production equipment and method for producing same {system and method for manufacturing of synthetic wood}

The present invention relates to a synthetic wood deck, and more particularly to a synthetic wood deck impregnated with fiber and resin, and a production apparatus and a production method for producing the same.

Generally, natural wood is mainly used as exterior materials or interior materials of buildings such as floorboards, ceiling boards, doors, door frames, windows, decks, and fences.

Thus, the natural wood used as the interior and exterior of the building can satisfy the consumer's preference for the wood and the beauty due to the natural texture.

However, the interior and exterior materials of buildings using such natural wood have problems of deforestation due to logging of wood and environmental destruction due to release of toxic substances in case of fire, and in particular, there is a problem in that water resistance, heat resistance, It is difficult to use as an exterior material of a building due to deterioration of strength, bending strength, dimensional stability, flame retardancy, weather resistance and antimicrobial properties of the building, and the antimicrobial property due to the wood material is lowered to shorten the life span. A chromium-based preservative (so-called CCA preservative) is mixed and used. Accordingly, when a fire occurs, the toxic substances due to the burning of the preservative of copper, arsenic, and chromium are discharged, which is harmful to the human body.

In order to overcome the disadvantages of such natural wood, synthetic wood having a texture and appearance similar to those of natural wood has been widely used as interior and exterior materials for buildings. The synthetic wood used in this manner is molded and used in various structures and shapes have.

Such a synthetic wood is formed by mixing a conventional thermoplastic resin with wood, and the synthetic wood molded from such a composition is used as an interior and exterior material of a building, thereby improving water resistance, heat resistance, dimensional stability, flame retardancy and antibacterial properties , And the manufacturing cost is reduced because the price is low.

In particular, recently, in order to improve the strength of the synthetic wood deck, as described in [Document 1], a synthetic wood deck having iron plates embedded in the synthetic wood was also developed and produced.

Figure 5 is a plan view of the production apparatus for producing a composite wood deck according to the present invention.
6 is a view showing a composite wood deck according to a fourth embodiment of the present invention.
7 is a block diagram of a production apparatus for producing a synthetic wood deck according to a fourth embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 5 are diagrams showing a synthetic wood deck and a production apparatus for producing the same according to an embodiment of the present invention.

Synthetic wood deck 1 according to an embodiment of the present invention, as shown in Figure 1, the core material (3) of the resin material is impregnated and molded with the fiber (4), the core 3 is fixed therein Synthetic wood (2) which is spaced apart at intervals and is extrusion molded into a composition of resin, wood flour and additives.

The core 3 is a composition in which 96.6% of a resin having a polypropylene melt index (PP MI) of 20 or more, 3% of an adhesive, and 0.4% of a primary antioxidant are mixed. It is formed of resin and fiber. Therefore, in forming the core 3, when the adhesive and the antioxidant are mixed more than the above-mentioned content, the amount of resin is relatively low, so that the impregnation force of the core 3 impregnated with the fiber 4 falls, and the adhesive and the antioxidant Is less than the aforementioned content, the adhesion of the core 3 is lowered.

Here, the fiber 4 is preferably composed of any one or two or more of glass fiber or carbon fiber or aramid or natural fiber.

The color supply unit 520 is configured with an extruder (not shown) as described above, the liquid color raw material (wood powder + resin + additives + iron oxide pigment) by the extruder supply chamber 521 inside the color supply unit 520 It is supplied to and extruded by the extrusion pressure to the surface of the synthetic wood (2c) to form the color layer (5) on the surface of the synthetic wood (2c). The color layer 5 formed as described above may have a concave-convex shape as shown in FIG. 6 due to the shape of the extrusion die 500.

In addition, the method for producing a synthetic wood deck (1c) using the production apparatus as described above, withdrawing the fiber (4) from each supply roll 100 and supplying to the impregnation dice 300, impregnation dice 300 While the fiber 4 is supplied inside, the first extruder 400 injects a composition including a resin, an adhesive, and an antioxidant into the impregnation die 300 to form the core 3a impregnated with the fiber 4. And the core 3a is supplied into the extrusion die 500 while the second extruder 600 includes a resin, wood flour, talc (flour), an adhesive, an active agent, a UV stabilizer, and an antioxidant. Injecting the composition into the extruded die 500 to form a composite wood 2c in which the core 3a is embedded, and a composite wood 2c in which the core 3a withdrawn from the extruded die 500 is embedded. Including the step of supplying the color from the color supply unit 520 to the surface to form a color layer 5, the color It will produce a composite wood deck (1c) with a layer (5) formed.

More specifically, the fiber 4 is drawn out from each supply roll 100 installed corresponding to the number of the impregnation chambers 310 of the impregnation die 300, and the drawn fiber 4 is attached to each guide roll 200. It is guided and supplied to the impregnation dice 300 side by.

The fiber 4 supplied in this way is 16 micrometers in 1 strand, and the fiber 4 pulled out from one supply roll 100 is about 1000-2400 strands.

On the other hand, the fibers 4 withdrawn from each supply roll 100 is divided into each impregnating chamber 310 of the pair of impregnation dice 300 is supplied, the first extruder 400 installed in the impregnation dice 300 is As the screw shaft 410 is driven to rotate by the motor M, the resin solution is supplied to each impregnation chamber 310 through a passage of the impregnation dice 300 to supply the core 3a impregnated with the fiber 4. Each will be molded.

In this way, the plurality of cores 3a formed in each impregnation chamber 310 of the impregnation die 300 are supplied to the upper and lower portions of the extrusion chamber 510 of the extrusion die 500, respectively, and are installed in the extrusion die 500. The second extruder 600 is a screw shaft 610 therein is rotated by the motor (M) to supply the composition of the resin, wood flour and additives to the extrusion chamber 510 of the extrusion die 500 by extruded die ( In 500, a composite wood 2c in which a plurality of cores 3a in which the fibers 4 are impregnated is formed.

On the other hand, if the synthetic wood (2c) with the core (3a) as described above is withdrawn from the extrusion die 500, the color supply unit 520 provided on the back of the extrusion die 500 on the surface of the synthetic wood (2c) The color layer 5 is formed by applying a color, and the color layer 5 formed as described above is formed in a concave-convex shape as shown in FIG. 6 according to the shape of the extrusion chamber 510 of the extrusion die 500. Can be.

Thus, the synthetic wood (2c) having a colored layer (5) formed on its surface is extruded from the extrusion die 500 by the continuous molding process, and the extracted synthetic wood (2c) is drawn out of the synthetic wood deck (1c) It is cut to the standard of and used as the final product synthetic wood deck (1c).
