Description
본 발명은 안티몬 등과 같은 중금속 유출에 의한 토양오염, 수질오염 유발이 없는 친환경적인 지오그리드 피복용 수성 코팅제 및 이를 이용한 친환경 지오그리드의 제조방법에 관한 것이다. The present invention relates to an eco-friendly water-based coating agent for coating a geogrid that does not cause soil contamination or water pollution by heavy metals such as antimony, and a method for manufacturing an eco-friendly geogrid using the same.
일반적으로, 토목공사를 실시할 때에 토양을 보강하기 위한 보강재가 다양하게 개발되고 있다. 섬유재료를 이용하는 대표적인 토목공사 보강재로는, 고분자 합성 수지 용액을 이용하여 제조되는 지오신세틱스(Geosynthetics)가 널리 알려져 있는데, 이는 투과성의 특성이 있는 지오텍스타일(Geitextile)을 비롯하여 차수성의 특성이 있는 지오맴브레인(Geomembrane), 그리고 보강도의 특성이 있는 지오그리드(geogrid)와 지오네트(Geonet) 및 지오컴포지트(Geocomposite) 등으로 개발되어 있으며, 초기에는 주로 토사의 세굴을 방지하고, 여과에 주로 사용되었으나, 근래에는 방수를 비롯하여 균열을 방지하고 지반구조물을 보호하며 충격을 흡수하는 등 다양한 용도로 사용되고 있다.In general, various reinforcing materials for reinforcing soil during civil engineering work have been developed. As a representative civil engineering reinforcing material using fiber materials, geosynthetics manufactured using a polymer synthetic resin solution are widely known. It has been developed into geomembrane, geogrid, geonet, and geocomposite with the characteristics of reinforcement. In the early days, it was mainly used to prevent soil scour and filter, , Recently, it is used for various purposes such as waterproofing, preventing cracks, protecting geotechnical structures, and absorbing shock.
상기 지오신세틱스(Geosynthetics) 중 지오그리드는 강성이면서 시트 형태로 제조되는 플라스틱 지오그리드와, 연성이면서 직물 형태로 제조되는 텍스타일 지오그리드로 구별되며, 플라스틱 지오그리드는 익히 알려진 바와 같이 폴리에틸렌 또는 폴리프로필렌으로 제조되는 시트에 구멍을 통공하고 일측 또는 양측에서 연신하여 제조되는 것이고, 텍스타일 지오그리드는 합성섬유를 격자 형태로 직조하고 그 외부(외면)에 수지용액(폴리염화비닐, 아크릴, 연청 등)을 코팅(피복)시켜 제조하도록 하는 것이 널리 알려져 있다.Among the geosynthetics, the geogrid is divided into a plastic geogrid that is rigid and manufactured in the form of a sheet and a textile geogrid that is flexible and manufactured in the form of a fabric. As is well known, the plastic geogrid is a sheet made of polyethylene or polypropylene. It is manufactured by passing through holes and stretching from one side or both sides. Textile geogrid is manufactured by weaving synthetic fibers in a lattice form and coating (covering) a resin solution (polyvinyl chloride, acrylic, soft blue, etc.) on the outside (external surface) It is widely known to do so.
상기 지오그리드는 크게 두 가지 형태로 나뉘는데, 하나는 통상 여러 가닥의 경사를 모아 경사 리브를 형성하고, 여러 가닥의 위사를 모아 위사 리브를 형성하여 통상의 경편기(Wrap Knitting Machine)를 이용해 격자 형태의 망으로 제직(제조)하며, 이와 같이 제직(제조)된 망의 외부에 수지용액 피복층을 코팅(피복)시켜서 형성한 것과, 다른 하나는 여러 가닥의 경사와 위사를 각각 모아 경사 리브와 위사 리브를 형성하고, 이를 통상의 경편기(Wrap Knitting Machine)에 의해 격자형태의 망으로 제직(제조)하되, 제직을 실시할 때에 경사리브와 함께 결합사를 공급하여 반복적으로 발생하는 경사 리브와 위사 리브의 교차부분을 지그재그로 통과시켜 결합사에 의해 교차부분을 일체형으로 엮어주도록 하며, 이와 같이 제직된 망의 외부에 수지용액 피복층을 코팅(피복)시켜서 된다.The geogrid is largely divided into two types. One is to form a warp rib by collecting several strands of warp yarn, and to form a weft rib by collecting several strands of weft yarn to form a lattice form using a normal warp knitting machine (Wrap Knitting Machine). It is woven (manufactured) with a net, and one is formed by coating (coating) a coating layer of a resin solution on the outside of the woven (manufactured) net, and the other is a warp rib and a weft rib by gathering several strands of warp and weft yarns, respectively. Forming and weaving (manufacturing) this into a lattice-shaped network by a normal warp knitting machine (Wrap Knitting Machine). The intersection portion is passed through in a zigzag pattern, and the intersection portion is integrally woven by bonding yarns, and a coating layer of a resin solution is coated (coated) on the outside of the woven net.
그리고, 지오그리드 제조에 형성되는 소재는 일반적으로 합성섬유이므로, 코팅공정에서 받는 고온의 열이력에 의해 원래의 물리적 성질 즉, 모듈러스, 신도 등의 물성이 변하게 되고, 특히 신도의 경우 열수축과 관련하여 심한 상승변화를 가져오게 되어 토목용 보강재로서의 목표한계 신도(대개 15% 미만이 바람직함)를 벗어나거나, 제품의 인장시험 시에 인장거동이 변화되어 장력 및 신률이 저하되는 등 문제점이 있다.In addition, since the material formed in the manufacture of geogrid is generally synthetic fiber, the original physical properties, that is, physical properties such as modulus and elongation, are changed by the high temperature thermal history received in the coating process. There are problems such as deviating from the target limit elongation (usually less than 15% is preferable) as a reinforcing material for civil engineering, or reducing tension and elongation due to change in tensile behavior during the tensile test of the product.
이러한 지오그리드 자체의 물성 변화를 방지하고 나아가 지오그리드의 물성 향상을 위해서 수지용액 피복층을 형성시키는데, 이러한 수지용액 피복층 소재로서 PVC(polyvinyl chloride) 수지를 주 수지로 사용한 코팅액을 주로 사용하였는데, 기존 지오그리드가 시공된 후, 피복층 즉, PVC 코팅층이 물과 만나게 되면 화학작용에 의해 변화가 일어나는 문제가 발생하고, 즉, 내수성, 내화학성이 약하고, 피복층으로부터 안티몬 등과 같은 중금속이 유출되어 토양 및/또는 수질오염을 일으키는 문제가 있었다. A resin solution coating layer is formed to prevent the change in the physical properties of the geogrid itself and furthermore to improve the physical properties of the geogrid. As a material for the resin solution coating layer, a coating solution using PVC (polyvinyl chloride) resin as the main resin was mainly used. After that, when the coating layer, that is, the PVC coating layer, encounters water, there is a problem of change by chemical action, that is, water resistance and chemical resistance are weak, and heavy metals such as antimony leak from the coating layer, causing soil and / or water pollution. There was a problem causing
이에, 내수성, 내화학성이 우수하면서 중금속 유출문제가 없으면서 지오그리드의 물성 약화 방지 내지 강화시킬 수 있는 새로운 친환경적인 지오그리드 피복층 형성용 코팅제에 대한 요구가 증대하고 있는 실정이다.Therefore, there is an increasing demand for a new environmentally friendly coating agent for forming a geogrid coating layer that can prevent or strengthen the physical properties of a geogrid while having excellent water resistance and chemical resistance and no heavy metal leakage problems.

In addition, the silonic acid-based latex may have an average particle size of 0.100 to 0.200 μm, preferably about 0.120 to 0.160 μm, and a weight average molecular weight of 85.000 g/mole or more, preferably a weight average molecular weight of 90,000 to 150,000 g/mole. .
다음으로, 코팅제 조성 중 상기 무기필러는 피복층의 내마찰성, 내충격성을 증대시키는 역할을 하는 것으로서, 실리카, 탄산칼슘 및 수산화알루미늄 중에서 선택된 1종 이상을 포함할 수 있고, 바람직하게는 실리카 및 탄산칼슘 중에서 선택된 1종 이상을 포함할 수 있다. 그리고, 상기 무기필러의 코팅제 내 함량은 코팅제 전체 중량% 중 5 ~ 10 중량%를, 바람직하게는 5.5 ~ 8.5 중량%, 더욱 바람직하게는 5.5 ~ 7.5 중량%로 사용할 수 있으며, 이때, 무기필러 함량이 5 중량% 미만이면 그 사용량이 적어서 피복층의 내마찰성, 내충격성을 증대 효과가 미비할 수 있고, 10 중량%를 초과하면 오히려 과량 사용으로 인해 코팅제의 코팅 작업성, 그리드에 대한 코팅 부착성을 떨어뜨리는 문제가 있을 수 있으므로 상기 범위 내로 사용하는 것이 좋다.Next, the inorganic filler in the composition of the coating agent serves to increase the friction resistance and impact resistance of the coating layer, and may include at least one selected from silica, calcium carbonate and aluminum hydroxide, preferably silica and calcium carbonate. It may include one or more selected from among. In addition, the content of the inorganic filler in the coating agent may be 5 to 10% by weight, preferably 5.5 to 8.5% by weight, more preferably 5.5 to 7.5% by weight, based on the total weight% of the coating agent. At this time, the inorganic filler content If the amount is less than 5% by weight, the effect of increasing the friction resistance and impact resistance of the coating layer may be insignificant due to the small amount used, and if it exceeds 10% by weight, the coating workability of the coating agent and the coating adhesion to the grid may be deteriorated due to excessive use. Since there may be a problem with dropping, it is recommended to use it within the above range.
다음으로, 코팅제 조성 중 상기 분산제는 코팅제 성분 중 라텍스 및 무기필러가 바인더 수지에 고르게 분산되도록 하며, 코팅제 조성들이 물에 잘 용해되도록 하는 역할을 하는 것으로서, 상기 분산제는 소듐비스(2-에틸헥실)설포석시네이트, 소듐라우릴설페이트, 소듐이소프로필나프탈렌설포네이트, 소듐비스(트리데실)설포석시네이트, 디소듐라우릴에테르설포석시네이트 및 암모늄스테아레이트 중에서 선택된 1종 이상을 포함할 수 있으며, 바람직하게는 소듐라우릴설페이트, 소듐이소프로필나프탈렌설포네이트 및 소듐비스(트리데실)설포석시네이트, 디소듐라우릴에테르설포석시네이트 중에서 선택된 1종 이상을 포함할 수 있고, 더욱 바람직하게는 소듐비스(트리데실)설포석시네이트 및 디소듐라우릴에테르설포석시네이트 중에서 선택된 1종 이상을 포함할 수 있다. 그리고, 상기 분산제의 코팅제 내 함량은 코팅제 전체 중량% 중 0.1 ~ 1.0 중량%를, 바람직하게는 0.4 ~ 1.0 중량%, 더욱 바람직하게는 0.5 ~ 0.8 중량%로 사용하는 것이 좋다. 이때, 분산제 함량이 0.1 중량% 미만이면 이의 사용량이 너무 적어서 조성물의 분산 효과가 미비하여 그리드에 형성된 피복층 표면이 고르지 못한 문제가 있을 수 있고, 1.0 중량%를 초과하면 오히려 초기 코팅성 및 그리드에 대한 피복층의 부착성이 떨어지는 문제가 있을 수 있으므로 상기 범위 내로 사용하는 것이 좋다. Next, the dispersant in the coating composition serves to evenly disperse the latex and inorganic filler in the binder resin and to dissolve the coating composition well in water, and the dispersant is sodium bis (2-ethylhexyl) It may contain at least one selected from sulfosuccinate, sodium lauryl sulfate, sodium isopropyl naphthalene sulfonate, sodium bis(tridecyl) sulfosuccinate, disodium lauryl ether sulfosuccinate and ammonium stearate. It may preferably contain at least one selected from sodium lauryl sulfate, sodium isopropyl naphthalene sulfonate, sodium bis(tridecyl) sulfosuccinate, and disodium lauryl ether sulfosuccinate, more preferably Preferably, at least one selected from sodium bis(tridecyl) sulfosuccinate and disodium lauryl ether sulfosuccinate may be included. In addition, the content of the dispersant in the coating agent is preferably 0.1 to 1.0% by weight, preferably 0.4 to 1.0% by weight, more preferably 0.5 to 0.8% by weight, based on the total weight% of the coating agent. At this time, if the content of the dispersant is less than 0.1% by weight, the amount of the dispersant is too small and the dispersing effect of the composition is insufficient, so that the surface of the coating layer formed on the grid may have an uneven problem. Since there may be a problem of poor adhesion of the coating layer, it is good to use it within the above range.
또한, 본 발명의 코팅제는 바인더 수지, 라텍스, 무기필러, 분산제 외에 안료, 점도증진제, 희석제, 안정제 등의 첨가제를 더 포함할 수도 있다.In addition, the coating agent of the present invention may further include additives such as pigments, viscosity enhancers, diluents, and stabilizers in addition to binder resins, latex, inorganic fillers, and dispersants.

The geogrid of the present invention, in which the coating layer is formed with the coating agent described above, has no change in elongation after construction, excellent mechanical properties such as tensile force, excellent water resistance and chemical resistance, and no leakage of heavy metals such as antimony. Since it does not contain phthalate-based plasticizers or volatile organic compounds (VOCs) such as toluene and xylene, it is possible to provide an environmentally friendly geogrid. The geogrid of the present invention can be applied as an eco-friendly reinforcing material for various civil engineering works such as retaining wall reinforcement, slope reinforcement, and soft ground reinforcement.

상기 제조예 1과 동일한 방법, 조건으로 친환경 지오그리드를 제조하되, 친환경 수성 코팅제로서, 실시예 1의 코팅제 대신 실시예 2 ~ 3 및 비교예 1 ~ 3의 코팅제를 사용하여 친환경 지오그리드를 하기 표 2와 같이 각각 제조하였다. An eco-friendly geogrid was prepared in the same manner and conditions as in Preparation Example 1, but as an eco-friendly water-based coating agent, using the coating agents of Examples 2 to 3 and Comparative Examples 1 to 3 instead of the coating agent of Example 1, an eco-friendly geogrid was prepared in Table 2 below. were prepared separately.
실험예 1 : 안티몬 용출 실험Experimental Example 1: Antimony Elution Experiment
제조예 1 내지 제조예 3에서 제조한 친환경 지오그리드의 안티몬 용출 여부를 측정하였고, 그 결과를 하기 표 3에 나타내었다. 그리고, 안티몬 용출 실험은 1L 용량의 둥근 플라스크에 증류수 1L, 염화칼슘(CaCl2) 3.2 mg 및 제조예 1, 제조예 2 또는 제조예 3의 지오그리드 5g을 넣고, 수산화나트륨(NaOH)를 pH가 8이 되도록 적정하였다. 그 후 상온(25℃에서 24 시간동안 유지시킨 후 직물을 꺼내고, 용액을ICP-MS(Perkin Elmer, NexION 300X)를 이용하여 안티몬의 용출량을 측정하였다.Antimony elution of the eco-friendly geogrids prepared in Preparation Examples 1 to 3 was measured, and the results are shown in Table 3 below.

실험예 2 : 지오그리드의 물성 측정Experimental Example 2: Measurement of physical properties of geogrid
제조예 1 ~ 3 및 비교제조예 1 ~ 3에서 제조한 지오그리드 각각에 대한 냄새, 내수성, 내알칼리성, 상대 인장강도 및 상대 인장신도를 하기 방법에 의애 측정하였고, 그 결과를 하기 표 4에 나타내었다.Odor, water resistance, alkali resistance, relative tensile strength and relative tensile elongation for each of the geogrids prepared in Preparation Examples 1 to 3 and Comparative Preparation Examples 1 to 3 were measured by the following method, and the results are shown in Table 4 below. .

(3) 내알칼리성 : KS M IOS 2812-1 시험방법 1에 따라 시험하였다.(3) Alkali resistance: Tested according to KS M IOS 2812-1 Test Method 1.
그리고, 냄새, 내수성 및 내알칼리성 평가 결과는 ○:우수, △:보통, Ⅹ:나쁨으로 나타내었다.In addition, the odor, water resistance and alkali resistance evaluation results were indicated as ○: excellent, △: normal, and X: poor.
(4) 상대 인장강도 및 상대 인장신도 : KS K ISO 10319에 따라 시험하여 인장강도(kN/m) 및 인장신도(%)를 측정한 후, 대조군의 인장강도 및 인장신도를 100% 기준으로 하여, 제조예 및 비교제조예의 지오그리드의 인장강도, 인장신도 측정값을 계산하여 나타내었다.(4) Relative tensile strength and relative tensile elongation: After testing in accordance with KS K ISO 10319 to measure tensile strength (kN / m) and tensile elongation (%), the tensile strength and tensile elongation of the control group are 100% based , The measured values of tensile strength and tensile elongation of the geogrid of Preparation Example and Comparative Preparation Example were calculated and shown.
이때, 대조군은 제조예 1에서 원단 표면에 피복층 형성 전의 그리드 원단이다. At this time, the control group is the grid fabric before forming the coating layer on the surface of the fabric in Preparation Example 1.
(5) 코팅성(5) Coatability

상기 표 3의 물성 측정결과를 살펴보면, 제조예 1 ~ 3 및 비교제조예 1 ~ 3 모두 대조군과 비교할 때, 우수한 냄새 평가 및 내수성 평가를 받았다. Looking at the physical property measurement results in Table 3, both Preparation Examples 1 to 3 and Comparative Preparation Examples 1 to 3 received excellent odor evaluation and water resistance evaluation when compared to the control group.
특히, 제조예 1 ~ 3은 모두 대조군에 비해 인장강도가 크게 증가하는 결과를 보였으며, 상대 인장신도가 크게 줄어서, 지오그리드의 신장 변화율을 크게 감소시킬 수 있음을 확인할 수 있었다.In particular, all of Preparation Examples 1 to 3 showed a significant increase in tensile strength compared to the control group, and it was confirmed that the relative tensile elongation was greatly reduced, so that the elongation change rate of the geogrid could be greatly reduced.
이에 반해, 바인더 수지로서, 아크릴 수지만을 단독으로 사용한 코팅제로 피복층이 형성된 비교제조예 1 및 바인더 수지를 40 중량% 미만으로 사용한 코팅제로 피복층이 형성된 비교제조예 2의 경우, 제조예 1~3과 비교할 때, 상대인장강도 증가율이 크게 감소하고, 특히 상대 인장신도가 감소가 적었으며, 이는 지오그리드를 시공한 후, 외부 환경 등에 의에 지오그리드가 수축될 확률이 높음을 의미하며, 이는 피복층이 그리드 표면에 대한 부착률, 접착 안정성이 떨어지고, 피복층이 고르게 형성되지 않았기 On the other hand, in the case of Comparative Preparation Example 1 in which the coating layer was formed with a coating material using only an acrylic resin as the binder resin and Comparative Preparation Example 2 in which the coating layer was formed with a coating material using less than 40% by weight of the binder resin, Preparation Examples 1 to 3 Compared to , the rate of increase in relative tensile strength was greatly reduced, and the decrease in relative tensile elongation was particularly small, which means that the geogrid is highly likely to shrink due to the external environment after constructing the geogrid, which means that the coating layer is The adhesion rate and adhesion stability to the surface are poor, and the coating layer is not formed evenly.
또한, 바인더 수지 함량이 65 중량% 초과한 66.1 중량%로 함유 코팅제로 피복층이 형성된 비교제조예 3의 경우, 상대 인장강도가 높고, 상대 인장신도가 낮은나, 코팅성이 좋지 못한 문제가 있었다. In addition, in the case of Comparative Preparation Example 3 in which the coating layer was formed with a coating agent containing 66.1% by weight of more than 65% by weight of binder resin, there was a problem of high relative tensile strength, low relative tensile elongation, or poor coating property.

Through the above examples and experimental examples, the water-based coating agent for geogrid coating of the present invention uses water as a solvent, and does not contain phthalate-based plasticizers or volatile organic compounds (VOCs) such as toluene and xylene, which are endocrine disruptors. In addition, it is an eco-friendly material that does not leak heavy metals such as antimony, but is applied as a coating layer of the geogrid, so that there is no change in elongation after construction, mechanical properties such as tensile strength, and water resistance. It is possible to manufacture a geogrid with excellent chemical resistance. I was able to confirm.
