Description

Water premeable paving material using fine granule type wood chip and its paving method using it according}

The present invention relates to a water-permeable pavement using a fine-grained wood chip and its construction method, to provide a fine-grained wood layer above the permeable support layer of the road, to improve the walkability while simultaneously having water permeability and eco-friendliness. The present invention relates to a permeable packaging material using a fine-grained wood chip and a construction method thereof.

In general, the trails and bicycle paths have been created to improve the convenience and health of the residents, and the trails and bicycle paths are provided with boundary stones at both sides between the landscape and the trees to expose the natural soil. When constructing bicycle roads or artificially constructing them, most of them are installed by speaking on the ground using a sidewalk block made of cement or by placing them on the ground using concrete and asphalt concrete.

Trails and bicycle paths that expose the conventional natural soil is a defect that the soil is washed in rainwater during rainy weather, the trails are easily lost and maintenance occurs frequently, and walkways and bicycles that are constructed with sidewalk blocks, concrete, asphalt, etc. The road is excellent in durability and easy to construct, but there is a problem that a large injury occurs in the body even when the user falls into a negligence or a light collision of the user.

In addition, in order to solve the above problems, by mixing rubber chips, silica sand and adhesives crushed waste tires in a certain size in a certain ratio to form a packaging material having a certain length and width, and then asphalt or concrete pavement surface The adhesive is applied to the package, and the molded packaging material is packaged in double to improve the safety of the user, but

Since the installation of the packaging material as described above should be made of a double packaging, it takes a lot of construction time, harmful substances can be emitted from the waste tire, and there is a problem that the appearance of the packaging material breakage occurs after construction, so that the appearance is not good.

In addition, the pavement, sidewalk block, concrete, etc. are not all nature-friendly and there are various problems, such as meeting the desire to be more familiar with the nature that people who visit the park in common.

The present invention is to solve the above problems, the object is to form a base or base layer and the surface layer of the road by an environmentally friendly wood chip, fine grain type that can satisfy the permeability and compressive strength suitable for the road at the same time The present invention provides a water-permeable packaging material using wood chips and a construction method thereof.

Still another object of the present invention is to provide a permeable packaging material and a construction method using fine grained wood chips that are walkable and environmentally friendly, and which can protect users through excellent resilience.

The upper wood layer 11 serves as a surface layer, and is directly installed on the water-permeable support layer 20 without the lower wood layer 12 or the lower wood layer 12 serving as a base layer, and is compressed and packaged. That is, the upper wood layer 11 is mixed with the fine-grained wood chips and chip binder made of dried natural wood compression packing on the upper side of the permeable support layer to a thickness of 5 ~ 50㎜, or lower to a thickness of 3 ~ 5mm Compression packed above the wood layer. The upper wood layer 11 formed as described above is made of fine chips, and has a slippery surface without being slippery even when human skin is in contact.

The upper wood layer 11 is a priority for comfort and safety of children, the elderly and all people walking, grain size 2 ~ 5㎜ fine grained wood chips can not be formed by the general shredding method, natural wood Primary shredding is performed by a shredder to form shredding chips having an average particle size of 50-100 mm, and the shredding chips are set to 10 mm or less in the saw blade spacing of cutters having 200 saw blades, and then shredded second to 6-8 mm. Polygonal wood chips are formed, which are operated on a paper-type rotator to process edges and crushed polygonal wood chips to form fine-grained wood chips with an average particle diameter of 2-5 mm.

The upper wood layer 11 formed as described above is made of fine chips, and has a slippery surface without being slippery even when human skin is in contact.

The chip binder is a wood-based adhesive having transparency and comprising a urethane-based adhesive or a natural tannin solution extracted from wood.

The wood-based adhesive is composed of 40 to 60 parts by weight of polyisocyanate compound, 15 to 40 parts by weight of ethylene glycol, and 5 to 8 parts by weight of hexamine in 100 parts by weight of a natural tannin solution extracted from wood.

The natural tannin aqueous solution is a powder that is extracted from wood and dried to dissolve in water, using a 30 to 60% by weight tannin aqueous solution. Since such a natural tannin solution is homogeneous with wood chips, it improves the adhesion performance of wood chips.

The hexamine functions as a reaction catalyst for the polyisocyanate compound and ethylene glycol, and promotes the crosslinking reaction between the natural tannin aqueous solution and the polyisocyanate compound.

The polyisocyanate compound is hexamethylene isocyanate or phenylene diisocyanate.

The chip binder (wood-based adhesive) thus formed is a urethane-based chip binder having excellent adhesion by the reaction of a polyisocyanate compound with ethylene glycol and hexamine. Adhesion is further enhanced by tannins that promote and insolubilize the crosslinking reaction, thereby providing excellent strength.

That is, the component ratio of the chip binder (wood-based adhesive) is to have excellent adhesion and strength, and should have an optimum blending ratio in consideration of the addition amount with other components.
