As shown in Figure 1 to 8, the wing panel loading box 100 according to an embodiment of the present invention, the bottom portion 110 and the bottom portion 110 to form a flat shape in a standing state The front support part 120 and the rear support part 125 which are erected, the core part 130 which connects the upper side of the front support part 120 and the rear support part 125, and extends in the longitudinal direction of the bottom part 110, and a core, Rotating bracket portion 140 is installed in a plurality along the longitudinal direction of the portion 130, the mounting bracket portion 150 fixed to the rotating bracket portion 140 and one side of the panel formed of the letter "A" mounting bracket portion It characterized in that it comprises a wing panel 180 which is fixed in the inserted state (150).

The bottom portion 110, in which a plurality of materials are mixed to form a flat plate shape, is formed in a plate shape by combining a plurality of plate pieces together, and is formed of a fiber-reinforced composite material, thereby preventing deformation due to moisture or sunlight. And it is possible to reduce the weight of the wing panel loading box 100 by the bottom portion 110 is formed of a lightweight material.

Bottom portion 110 is formed in a plate shape and extends in the longitudinal direction (D) of the wing panel loading box (100). Along the width direction (W) of the wing panel loading box 100 is provided with a bottom portion 110 consisting of a plurality of members in succession, the bottom portion 110 facing each other forms a step that is alternately coupled to each other. The frame frame 112 is installed below the bottom 110 to support the bottom 110.

The method of manufacturing the bottom part 110 has a step of preparing a thermoplastic resin composition. 100 parts by weight of a composition composed of an olefin-based thermoplastic resin such as polyethylene or polypropylene or a combination with other materials is defined.

And, based on 100 parts by weight of the thermoplastic resin composition has a step of preparing 60 to 160 parts by weight wood flour. The humidity contained in the wood flour material pre-drys the wood flour material because it adversely affects the formation of the surface of the raw material and the product and causes voids. Drying of wood flour should be lower than 200 ° C if possible due to prolonged exposure to high temperatures, which can lead to the release of volatiles, discoloration, odor and deterioration of wood components.

Wood flour can be made by grinding recycled materials such as chips, shavings and sawdust into fine powder. The particle size of wood flour is in the range of 20 ~ 120mesh and the ratio of length to diameter of wood flour is about 3: 1 to 5: 1.

And, based on 100 parts by weight of the thermoplastic resin composition has a step of preparing a coupling agent in 3 to 10 parts by weight. As the thermoplastic resin composition, polyethylene (PE), polyvinyl chloride (PVC), and polypropylene (PP) are used.

Coupling agents, also known as binders, are used to improve the bond between the thermoplastic resin composition from which plastic is a material and wood flour. In principle, the wood flour material has a hydrophilic polarity and the plastic thermoplastic composition has a non-polar hydrophobicity. Therefore, the bonding strength between the two materials is weak, and the addition of the binder improves the new chemical bonding at the interface between the two materials.

Technically, the coupling agent increases the modulus of rupture (MOR) and modulus of elasticity (MOE) and affects the dimensional stability of the product, the impact strength and the distribution of wood flour.

After the thermoplastic resin composition, the wood flour material and the coupling agent are mixed, the bottom part 110 is extruded by an extruder.

In addition, before mixing the thermoplastic resin composition, the wood flour material and the coupling agent, may further have a step of preparing 10 to 50 parts by weight of the reinforcing fibers based on 100 parts by weight of the thermoplastic resin composition.

Into 100 parts by weight of a thermoplastic resin composition composed of a single or combination of olefin-based thermoplastic resins such as polyethylene and polypropylene, wood powder material dried within a moisture content of 3% is mixed at 60 to 160 parts by weight compared to the thermoplastic resin composition, and carbon fibers and glass fibers After mixing the reinforcing fibers such as 10 to 50% by weight compared to the thermoplastic resin composition, kneading using an extruder (Screw extruder), manufactured by the bottom portion 110 of the wing panel loading box 100 using an extrusion die. do.

The front support part 120 is installed in a state standing on one side of the bottom portion 110, the rear support portion 125 facing the front support portion 120 is installed in a state standing on the other side of the bottom portion (110). According to an embodiment, the front support part 120 has a plate shape, and the rear support part 125 functions as a door for opening and closing the wing panel-type loading box 100.
