Abstract

A cargo support includes an upper panel having a freight loaded on; a lower panel associated with the upper panel via a plurality of spacers to have the upper panel separated from the ground at a predetermined height; and a plurality of insert openings, each provided between the adjacent spacers associated with each other in the horizontal direction and separated from each other at a predetermined distance to have a fork inserted thereinto, where the upper and lower panels includes a wood polymer/plastic composite material prepared by using wood flake chips as a principal ingredient.

First claim

What is claimed is:

1. A cargo support using a wood polymer/plastic composite material comprising:
an upper panel having a freight loaded on;
a lower panel associated with the upper panel via a plurality of spacers to have the upper panel separated from the ground at a predetermined height; and
a plurality of insert openings, each provided between the adjacent spacers associated with each other in the horizontal direction and separated from each other at a predetermined distance that a fork can be inserted thereinto,
wherein the upper and lower panels comprise a wood polymer/plastic composite material prepared by using wood flake chips as a principal ingredient,
wherein the wood polymer/plastic composite material is molded from a compound comprising 10 to 90 parts by weight of wood flake chips, 10 to 50 parts by weight of a polymer resin and long fibers,
wherein the wood flake chips and the long fibers are included in an amount of 10 to 90 parts by weight.

2. The cargo support using a wood polymer/plastic composite material as claimed in claim 1 ,
wherein the polymer resin comprises at least one selected from the group consisting of PP, PE, PVC, ABS, PS, PC and PMMA.

3. The cargo support using a wood polymer/plastic composite material as claimed in claim 1 , wherein, in the compound, the wood flake chips and the long fibers are included in an amount of 50 to 90 parts by weight.

4. The cargo support using a wood polymer/plastic composite material as claimed in claim 1 , wherein the compound optionally comprises additives including 0.1 to 50 parts by weight of a compatibilizer, 0.1 to 50 parts by weight of a filler, 0.1 to 30 parts by weight of an antioxidizer, 0.1 to 30 parts by weight of a lubricant, and 0.1 to 30 parts by weight of a pigment.

5. The cargo support using a wood polymer/plastic composite material as claimed in claim 1 , wherein the wood flake chips are cut to a length of 0.3 to 18 cm.

6. The cargo support using a wood polymer/plastic composite material as claimed in claim 1 , wherein the wood flake chips are cut to a length of 3 to 8 cm.

7. The cargo support using a wood polymer/plastic composite material as claimed in claim 1 , wherein the long fibers comprise at least one selected from the group consisting of natural fibers, including corn fiber, coconut fiber, palm tree fiber, reed, bamboo, rice straw, cotton, bast fiber, wool, or silk; reinforced polymer fibers, including glass fiber, carbon fiber, or nylon; and steel wire.

8. The cargo support using a wood polymer/plastic composite material as claimed in claim 7 , wherein the long fibers are cut to a length of 0.3 to 18 cm.

9. The cargo support using a wood polymer/plastic composite material as claimed in claim 1 , wherein the compound optionally comprises at least one recycled material selected from the group consisting of recycled paper, recycled resin, and recycled wood.

10. The cargo support using a wood polymer/plastic composite material as claimed in claim 1 , wherein the compound is molded into the wood polymer/plastic composite material through any one of extrusion, injection or press molding.
