Description

TECHNICAL FIELD The present invention relates to a liquid resin injection method and apparatus therefor,

The present invention relates to a method for manufacturing a panel in a furniture factory or a panel processing company, which is the most time consuming method of injecting a liquid resin.

According to the prior art, a method of manufacturing a panel in which waste wood is recycled according to a prior art publication 10-2010-0091760 (2010.08.19) includes a waste wood collection step (S10), a waste wood attaching step (S20) A pressing step S30, a panel forming step S40, and a finishing step S50.

The waste wood collection step (S10) uses wood discarded at a construction site or a woodworking site. The waste wood can be selectively used according to the use of the waste wood of grade 1 to grade 3 irrespective of the above-mentioned grade. The waste wood includes scrim wood, panel, etc. in addition to the above-mentioned 1 to 3 grade scrap wood.

The step of attaching waste wood (S20) is a step of attaching the collected waste wood in the form of a panel using a binder, and the binder may be a commonly used organic or inorganic adhesive or a thermoplastic resin such as a polyethylene resin.

It is preferable that the thickness of the binder layer formed after the coating is within a range of 0.1 to 2 mm. When the waste wood is adhered, it is preferable that the painted portions of the waste wood are adhered so as to face each other.

In the heating and squeezing step S30, waste wood attached in a panel shape is transferred to a heating device, heated for a predetermined time, and then pressurized with a pressing roller to improve the fixability of the waste wood.

The heating apparatus is preferably a known one and is preferably heated at a heating temperature of 50 to 90 ° C and a heating time of 5 to 10 minutes. Such a heating temperature and time develops the expansion characteristics of the binder so that the binder can be naturally bonded between the waste woods.

The binder applied to the panel-shaped waste wood is infiltrated with the waste wood in the process of being pressed at a certain pressure by the pressing roller, thereby firmly bonding the waste wood and the waste wood.

The panel forming step S40 is a step of cutting the panel-shaped waste wood that has been subjected to the above-described heat-pressing step S30 to a size suitable for use with a cutting device (not shown). When cutting, it is desirable to hold the waste wood with a press machine (not shown) in order to maintain the fixability of the waste wood.

The panel forming step S40 is preferably performed in two steps. First, the edge of the panel-shaped waste wood is cut to meet the standard to be used. Next, the panel-shaped waste wood in which the edges are cut is cut in the lateral direction so as to have a thickness to be used, preferably 5 to 20 mm. The scrapped panel-shaped waste wood is spread widely and attached to each other to finish the panel shape step (S40).

When the above-described panel-shaped waste wood is cut in the lateral direction, there is an advantage that the layer which has been painted or coated on the cut wood can be removed from the cut surface.

The finishing step (S50) is a step of applying a finishing member to the surface of the panel, and the finishing member preferably uses a silicone resin containing acrylic and silicon. The finishing member is preferably applied to the surface of the panel so as to have a thickness of 0.1 to 1 mm.

When a panel completed by the above-mentioned steps is used mainly for interior use of buildings such as flooring, wall materials, ceiling materials, etc., decorative paper, decorative sheet, patterned wood board and the like may be adhered to the surface of the panel with an adhesive. The step of attaching the decorative paper, the decorative sheet, and the like described above is also included in the finishing step (S50).

However, this method is inconvenient because the recycled wood is displayed on the surface of everybody, which causes the user to be uncomfortable and the price to be purchased for the user to be low. Accordingly, the manufacturer avoids the manufacturing of the recycled product It is a reality.

On the other hand, it is required that the impression of recycling is not given, and there is a need for the producers to generate profits, even though the appearance of the product and the appearance of the plate are not obstructed at all.

What is most required is an apparatus for injecting liquid resin.

In the present invention, it has been demanded to invent an apparatus for injecting a liquid resin into a panel inexpensively and effectively.
