[Chemical Formula 1]

In the above formula, n is a natural number of 1 to 10.

Hereinafter, constituent elements constituting the facility environment maintenance mat will be described.

The nonwoven fabric forming the upper and lower nonwoven fabric layers and the intermediate nonwoven fabric layer may be any one or more selected from the group consisting of polyester, polypropylene, rayon, nylon, carbon fiber, PVC (polyvinyl chloride) Can be used.

The nonwoven fabric layer functions to prevent loss of the fast-curing type polymer cement. When the water-caking type polymer cement is cured, the nonwoven fabric layer functions to easily pass water.

The polymer mesh layer serves to prevent the upper nonwoven fabric layer from being pushed when sewing to fix each layer of the laminate.

The polymer mesh forming the polymer mesh layer may be at least one selected from the group consisting of Ethylene Copolymer Bitumen (ECB), Ethylene Propylene Diene Monomer (EPDM), Ethylene Vinyl Acetate (EVA), and High Density Polyethylene Can be used.

Hereinafter, the components included in the fast-curing type polymer cement will be described in detail.

The ultrafine cement may have a Blaine fineness of 4,000 to 6,000 cm < 2 > / g. The ultrafine cement is very fine in comparison with the Blaine fineness (Blaine fineness) of ordinary Portland cement, which is in contact with water so that the hydration reaction of the cement proceeds quickly, and the initial strength of the fast curing type polymer cement And exhibits high characteristics. If the ultrafine cement is contained in an amount less than 40% by weight, there is a problem that the initial strength of the cement is insufficient. When the ultrafine cement is contained in an amount exceeding 55% by weight, the number of perforations increases.

As the epoxy resin, at least one selected from bisphenol A type epoxy resin, novolak phenol type epoxy resin and alicyclic epoxy resin can be used. The epoxy resin plays a role in imparting an immediate adhesive force to a composition for greening and soil stabilization when a composition for greening and soil stabilization is sprayed on a slope. In addition, the epoxy resin functions to improve the mechanical properties of the composition for greening and soil stabilization.

Commercially available epoxy resins include YD 115, 127, 128, 134, YDPN 631, 636, 637, 638 of Kukdo Chemical, Epikote 815, 827, 828, 834 of Shell Chemical Co., Dow Chemical DER 331, 332, 334, 337 of Dow Chemical Co.).

The compound of formula (1) has a structure in which three epoxy groups are introduced at both ends of the urethane skeleton and a silane group is introduced into the amine group of the urethane skeleton.

Due to the above-mentioned structural features, the compound of the following formula 1 reacts with ultrafine cement and epoxy resin to form a bond and also strongly bonds with the nonwoven fabric layer and the polymer mesh layer, Since the three-dimensional network structure is formed, the fast-curing polymer cement layer has strong durability. [ Chemical Formula 1]

In the above formula, n is a natural number of 1 to 10.

The compound represented by the formula (1) is preferably contained in an amount of 3 to 7% by weight. If it is contained within the above-mentioned range, it is difficult to achieve the objective effect, and if it exceeds, the viscosity of the composition becomes high, and the construction may become uncomfortable.

The amine-based curing agent may be a conventional polyamine-based or modified aliphatic amine-based, modified-earth-based amine-based, modified aromatic amine-based or modified polyimide-based.

The compound represented by the following general formula (2) or (3) is used for preventing the salt-encapsulation of the fast-curing type polymer cement layer.

[Chemical Formula 1]

(2)

The deterioration of the concrete due to the chloride occurs when the chloride reacts with the cement hydrate, Ca (OH) ₂ , to form crystals such as CaO · CaCl ₂ · 2H ₂ O and Mg ₂ (OH) ₃ Cl · 4H ₂ O, And partly due to the increase in porosity due to elution to the outside. However, deterioration of chloride ion (Cl ^- ) penetration into concrete is more serious than deterioration of concrete itself due to such chemical action.

Compound of Formula 2 or Formula 3 is Cl ^- and prevents the ions from entering the boundary stone structure ^- Cl by fixing the ^ion-ion reaction by Cl.

In particular, the compound of formula (2) or (3) may contain both an organic component and an inorganic component (Si or the like), thereby exhibiting a more preferable effect because it can be firmly, stably and uniformly mixed in the concrete composition.

The fly ash is an inorganic fine powder obtained by refining process, which is a dust precipitate generated when the oil / anthracite fuel such as a power plant is burned. Since the soil colloid and various inorganic dyes coexist, the degree of base saturation and the displacement capacity are increased. 0.002 to 0.012 should be maintained at 60% or more.

The Blast Furnace Slag and Calcium Carbonate are inorganic fine powders which maintain or enhance the long-term strength and improve the durability by making the hydrated structure of concrete concrete dense. If the blast furnace slag and the calcium carbonate are contained in the above-mentioned range, there is a problem that the chemical resistance such as corrosion resistance is poor. If the blast furnace slag and the calcium carbonate are contained in the above range, the durability becomes rather insufficient.

The aluminate-containing economy is an inorganic compound having a specific gravity of 1.50 ± 0.02 (20 ° C) and serves to obtain the compressive strength in a short time. If the aluminate flux economy is exceeded by the above-mentioned range, it may become insufficient in the fast-curing type or may be cured early due to the rapid curing phenomenon.

The aluminate swelling agent prevents drying shrinkage due to a rapid hydration reaction, thereby preventing generation of cracks and durability deterioration. If the aluminate swelling agent is included in the range out of the above range, the swelling property may be deteriorated at the initial stage, and cracks or swelling may occur.

The fluidizing agent is a large cement which has high fluidity by adding a high performance fluidizing agent excellent in the dispersibility of cement particles to concrete and has no effect on concrete quality and has a great effect of preventing temperature cracking. If the fluidizing agent is included in a range outside the above-described range, there is a problem that the fluidity is low and the workability is deteriorated, or bleeding, material separation, air amount decrease, and the like may occur.

The aggregate has an aggregate having a particle size of 0.1 to 0.9 mm, and the concrete strength is improved when the aggregate is used. When the aggregate is contained in an amount less than 0.01% by weight, the strength is weakened. When the aggregate is contained in an amount exceeding 25% by weight, cracks are caused.

In the facility environment conditioning mat of the present invention, the sewing needles the lower nonwoven fabric layer, the fast-light polymer cement layer, the polymer mesh layer, and the upper nonwoven fabric layer using a durable yarn. The durable yarn is not particularly limited, but polyethylene terephthalate or the like may be used.

The stitching is not particularly limited as long as it is a method of fixing the constituent elements of each layer. For example, when sewing in the form of a mesh, components of each layer can be firmly fixed, and the loss of fast-curing polymer cement can also be prevented.

For example, the stitching may be performed in such a manner that the thread passes through the upper and lower portions of the laminate so that each layer maintains its shape, or may be performed in a mu-beam manner.

 In order to prevent the loss of fast curing polymer cement, the side of the facility environment maintenance mat may be sealed by an adhesive method or sewing by extending the upper nonwoven fabric or the lower nonwoven fabric.

The waterproof sheet may be a liquid waterproofing material such as a polyurethane, a polyurea, an epoxy and a molten asphalt, an ethylene block copolymer (ECB) sheet, an ethylene propylene diene monomer (EPDM) sheet, an ethylene vinyl acetate sheet, an HDPE (High Density Polyethylene) A sheet, and a sheet.

The waterproof sheet not only prevents the loss of the fast-curing type polymer cement but also can suppress the supply of water to suppress weeds in drainage, ditches, and banks.
