To this end, the composition of the core part 60 having excellent durability according to an embodiment of the present invention includes 5 to 25% by weight of a binder solution, 50 to 80% by weight of a filler, and 1 to 20% by weight of a colorant.

The binder solution is added to improve strength and durability by improving bonding strength.

Such a binder solution is preferably added in a content ratio of 5 to 20% by weight of the total weight of the composition of the core part 60, and a more preferable range may be 10 to 15% by weight.

When the content of the binder solution is less than 5% by weight of the total weight of the composition for the core part 60, it may be difficult to secure strength and durability. On the contrary, when the content of the binder solution exceeds 20% by weight of the total weight of the composition for the core part 60, the viscosity is lowered, making it difficult to secure adhesion, and it is not economical because it can act as a factor that increases only manufacturing cost without increasing the effect. .

More specifically, the binder solution contains 20 to 30% by weight of ethylene, 20 to 30% by weight of vinyl acetic acid, 1 to 5% by weight of additives, and the remaining solvent.

The binder solution of the present invention forms an ethylene vinylacetic acid copolymer by copolymerization reaction between ethylene and vinylacetic acid. This ethylene vinyl acetic acid copolymer has the advantage that it can be used in all seasons because it does not harden at low temperatures and does not dissolve at high temperatures. In addition, the ethylene vinyl acetic acid copolymer enhances the bonding strength and improves durability and adhesion.

As the additive, at least one of a freezing stabilizer for improving fluidity, strength and durability, and an antifoaming agent for increasing strength and durability by removing pores in the binder is used.

These additives are preferably added in a content ratio of 1 to 5% by weight of the total weight of the binder solution. When the content of the additive is less than 1% by weight of the total weight of the binder solution, it is difficult to properly exhibit the effect of improving strength and durability. Conversely, when the content of the additive exceeds 5% by weight of the total weight of the binder solution, the viscosity increases and workability decreases.

These additives may include one or more of a cryo stabilizer and a defoamer.

Freeze stabilizers are added to improve fluidity, strength and durability. Refrigeration stabilizers can be polycarboxylic acid, melamine or naphthalene freeze stabilizers, but naphthalene and melamine can reduce the strength and workability, so the polycarboxylic acid freeze stabilizer does not decrease the strength and workability. It is more preferable to use.

Defoamers are used to increase strength and durability by removing pores in the binder. In addition, when the antifoaming agent is added together with ethylene and vinyl acetic acid, it is possible to improve workability and pot life by providing an air entrainment effect.

As the antifoaming agent, an alcohol-based antifoaming agent, a silicone-based antifoaming agent, a fatty acid-based antifoaming agent, an oil-based antifoaming agent, an ester-based antifoaming agent, an oxyalkylene-based antifoaming agent, and the like can be used. Examples of silicone antifoaming agents include dimethyl silicone oil, polyorganosiloxane, and fluoro silicone oil. Fatty acid-based antifoaming agents include stearic acid and oleic acid. Oil-based antifoaming agents include kerosene, animal and vegetable oil, and castor oil. Examples of ester antifoaming agents include solitol trioleate and glycerol monoricinolate. Examples of the oxyalkylene antifoaming agent include polyoxyalkylene, acetylene ethers, polyoxyalkylene fatty acid esters, and polyoxyalkylenealkylamines. Alcohol-based antifoaming agents include glycol.

Water may be used as the solvent, but is not limited thereto.

Fillers are added to improve strength and durability. Filling materials include at least one of remital, mortar, silica sand and gravel.

The filler is preferably added in a content ratio of 50 to 80% by weight of the total weight of the composition for the core part 60, and a more preferable range may be 60 to 70% by weight. When the content of the filler is less than 50% by weight of the total weight of the composition for the core part 60, it may be difficult to secure strength and durability. On the contrary, when the content of the filler exceeds 80% by weight of the total weight of the composition for the core part 60, there is a problem in that the amount of the filler is excessive and thus flowability and workability are deteriorated.

The colorant is added for pedestrians to easily identify the deck portion 30 of the rigid reinforcing deck structure 1. As a colorant, a more vivid color can be easily identified and the color persistence can be improved. As the colorant, at least one selected from color cement, red iron oxide, yellow iron oxide, chromium oxide, purple iron oxide, and carbon black may be used, of which color cement is more preferable. By the addition of a colorant, the composition for the core part 60 of the present invention may have various colors such as red, green, yellow, black, blue, and white.

These colorants are preferably added in a content ratio of 1 to 20% by weight of the total weight of the composition for the core part 60. When the content of the colorant is less than 1% by weight of the total weight of the composition for the core part 60, it may be difficult to achieve a desired color due to poor color expression. On the contrary, when the content of the colorant exceeds 20% by weight of the total weight of the composition for the core part 60, it is not economical because it can act as a factor that increases only the manufacturing cost without further increasing the effect.

The composition for the core part 60 having excellent durability according to the embodiment of the present invention described above uses a binder solution that forms an ethylene vinyl acetic acid copolymer by a copolymerization reaction between ethylene and vinyl acetic acid, thereby strengthening the bonding strength and durability. And strengthens adhesion.

As a result, the composition for the core part 60 having excellent durability according to the embodiment of the present invention, unlike natural wood or synthetic wood, has excellent durability and adhesion when used as the core part 60, so it is difficult to weather in snow or rain. There is no fear of damage even in the situation, it can be used for a long time, and maintenance and replacement costs are low.
