Meanwhile, in the folding pallet for export according to the present invention, a coating layer can be formed using a coating composition to exhibit anti-slip and anti-rust effects on the surface of the bottom floor 10 or the post 30, or both. .

The coating composition includes 30 to 40 parts by weight of butadiene rubber (BR), 20 to 30 parts by weight of acrylic acid, 10 to 20 parts by weight of silicate, and 5 to 10 parts by weight of aluminum flake, based on 60 to 70 parts by weight of acrylic resin (polypropylene, PP). 5 to 10 parts by weight of zinc flakes, 10 to 15 parts by weight of plasticizer, 5 to 10 parts by weight of nucleating agent, and 0 to 5 parts by weight of solvent to form a coating layer to obtain properties that prevent slipping and static electricity. there is.

The acrylic resin has excellent durability and impact resistance when forming a coating layer, and is widely used as a resin component. In particular, it is preferable to use one with a weight average molecular weight of 10,000 to 50,000, which can be selected considering compatibility with other components constituting the composition.

The butadiene rubber simultaneously exhibits the properties of plastic and rubber and has excellent compatibility with acrylic resin, so it exhibits the ability to reduce slippage by being included in the composition. The SBS is contained in the range of 30 to 40 parts by weight to exhibit anti-slip properties. If the SBS content is too small, the anti-slip properties of the coating layer are insufficient, and if the SBS content is too much, the coating performance of the coating composition deteriorates and the durability of the coating layer decreases. .

In addition, the acrylic acid is a crosslinkable monomer that is used to improve surface hardness and adhesion by increasing the degree of crosslinking of the resin. If the content of acrylic acid is too small, curing may proceed insufficiently and surface hardness may decrease, and if it is too much, cracks in the coating layer may occur or adhesion may be reduced.

Additionally, the silicate may be contained to disperse the rust preventive agent. Sodium silicate, potassium silicate, or colloidal silica can be used as the silicate. If the content of the silicate is too small, the dispersibility of the rust preventive agent decreases, thereby reducing the rust prevention effect, and if the content of the silicate is too much, the adhesion of the coating layer may decrease.

In addition, the aluminum flake and zinc flake have a faster corrosion rate than iron and act as a rust preventive to prevent corrosion of the substrate. The flakes are plate-shaped particles and are preferably classified into a particle size of 150 mesh or more in consideration of dispersion in the composition. The aluminum flake and zinc flake are preferably contained in a weight ratio of 2:1 to 1:1, but it has been shown that if the weight ratio is outside the above range, rust prevention and adhesion may be reduced.

In addition, the plasticizer is an ingredient added to improve the processability of a composition combining PP and SBS. Generally, phthalate plasticizers are used, but in the present invention, dioctyl terephthalate (DOTP), a non-phthalate plasticizer, can be used. The plasticizer is used in the range of 10 to 15 parts by weight. If the content of the plasticizer is too small or too large, the processability of the coating composition may be insufficient and the durability of the coating film when coated on the surface may be reduced, so it is used in the above range. It is desirable.

Additionally, a nucleating agent is used to achieve the function of shortening the curing time in a coating composition in which different types of resins are mixed. As the nucleating agent, components such as silica, aluminum hydroxide, talc, and kaolin are generally used, and in the present invention, silica with an average particle size of 1 to 30 μm is used. It has been shown that the use of the silica can shorten the curing time by increasing the compatibility of the resin contained in the coating composition of the present invention. In addition, to improve dispersibility, silica with an average particle size of 1 to 30㎛ is used. It was found to be desirable to use. If the particle size is too small, the process efficiency is lowered and the dispersion degree or dispersion deviation is lowered. If the particle size is too large, the dispersion degree of the nucleating agent is lowered, which reduces the effect of shortening the curing time and causes defects in the coating film when forming the coating layer. appeared to occur.

Additionally, any one of methanol, ethanol, propanol, and isopropanol can be used as the solvent. The solvent does not need to be used, but if used in excess of 5 parts by weight, the mechanical properties of the coating layer may deteriorate, so it must be used in an appropriate amount as needed.

In addition, in addition to the above ingredients, a small amount of additives can be added. Such additives include coupling agents, antioxidants, UV stabilizers, flame retardants, pigments, heat stabilizers, dispersants, etc., and are added in an amount of 1 to 100 parts by weight per 100 parts by weight of PP. It may be contained in the range of 5 parts by weight.

In the above description of the present invention, the "export folding pallet" having a specific shape and structure has been described with reference to the accompanying drawings. However, the present invention can be modified and modified in various ways by those skilled in the art, and such modifications and changes are consistent with the present invention. It should be interpreted as falling within the scope of protection.
