본 발명은 폐부직포와 폐비닐을 이용한 경계블록 및 이의 제조방법에 관한 것이다.The present invention relates to a boundary block using waste nonwoven fabric and waste vinyl and a method of manufacturing the same.

농사용 하우스 내부의 보온제로 사용되고 있는 부직포, 보온덮개는 통상적으로 도 7에 도시한 바와 같이 중간부분에는 폴리에스테르 화이버를 바깥부분에는 폴리프로필렌 부직포를 이용하여 이불처럼 제작한 것을 사용하고 있어, 통상적으로 4-5년 사용 후에는 보온력도 떨어지고 낡아서 더이상 사용이 곤란하여 폐기처분을 하고 있다. Non-woven fabric, a heat insulating cover that is used as a thermal insulation inside the house for farming, as shown in Figure 7 is usually used to produce a blanket using a polyester fiber in the middle portion and a polypropylene nonwoven fabric in the outer portion, it is usually 4 -After 5 years of use, the thermal insulation power is lowered and it is difficult to use because it is old and disposed of.

이렇게 폐기처분 된 폐부직포는 종래까지 화학적, 물리적 성분 차이와 부직포 속에 미세 흙먼지의 혼합으로 재활용이 불가능하여 소각하는 방법으로 폐기물을 처리하는 실정이다.The waste nonwoven fabric disposed of in this way is not recycled due to the mixing of chemical and physical components and the mixing of fine dust in the nonwoven fabric until now.

농사용 폐비닐의 경우에도 연간 폐비닐 발생량이 23만 톤이 발생되어 재활용되고 있으나, 하지만 재활용되는 양보다 발생량이 더 많아 재활용방안이 더 필요한 실정이다.Even in the case of agricultural waste vinyl, 230,000 tons of waste vinyl is generated annually and recycled.

더욱이 최근 들어 발생하고 있는 폐비닐의 경우 일본산 수입 PO(Polyolefin, 폴리올레핀) 필름의 폐비닐이 대량으로 발생하고 있으나 일본산 수입 PO필름의 경우 재활용시 PO필름에 포함된 유리성분에 의해 팰릿(pallet)으로 뽑을 때 연신율이 낮아 끊어져 버림에 따라 작업이 어려운 문제가 있는 것이다.In addition, in recent years, waste vinyl produced in Japan has produced a large amount of waste vinyl in imported polyolefin (Polyolefin) films, but in the case of imported PO film in Japan, pallets are recycled due to the glass content contained in the PO film. When you draw with), the elongation is low, the work is difficult to cut off.

도 1은 본 발명의 실시 예에 따른 경계블록의 단면구성도이고, 도 2 내지 도 3은 실물 경계블록을 찍은 사진도이며, 도 4는 경계블록을 제조하는 과정을 도시한 도면이다.1 is a cross-sectional configuration diagram of a boundary block according to an embodiment of the present invention, Figures 2 to 3 is a photograph showing a physical boundary block, Figure 4 is a view showing a process of manufacturing the boundary block.

본 발명의 경계블록(6)은 농사용으로 사용되는 폐부직포와 폐비닐을 용융압출시켜 혼합한 재생수지(2)를 금형(12a)(12b)에 넣어 사출성형하여 경계블록(6)을 제조하되, 상기 재생수지(2)는 폐부직포와 폐비닐이 7:3의 중량비로 혼합하여 구성되며, 바람직하게는 폐부직포와 폐비닐이 6~8:2~4의 중량비로 혼합되게 구성된다.Boundary block (6) of the present invention is to produce a boundary block (6) by injection molding the recycled resin (2) mixed by melt extrusion of the waste nonwoven fabric and waste vinyl used for farming in the mold (12a) (12b) The recycled resin 2 is composed of a waste nonwoven fabric and waste vinyl mixed at a weight ratio of 7: 3, and preferably, a waste nonwoven fabric and waste vinyl are mixed at a weight ratio of 6-8: 2-4.

또한, 도 4의 (a)에서와 같이 재생수지(2)를 이용하여 경계블록(6)을 사출성형한 후 완전히 경화되기 전에 색소를 혼합한 폐비닐 수지(4)를 도 4의 (b)와 같이 다시 투입하여 2차로 사출성형함으로써 경계블록(6)의 외관이 어두운 부직포 색이 아닌 사용용도에 맞는 다양한 색상을 갖도록 할 수 있어 외관미를 높일 수도 있다.In addition, as shown in (a) of FIG. 4, after the injection molding of the boundary block 6 using the recycled resin (2), the waste vinyl resin (4) in which the dye is mixed is completely cured. By re-injection as shown in the second injection molding, the outer appearance of the boundary block 6 may have various colors suitable for use instead of the dark non-woven fabric color.

앞서 설명하였듯이 폐부직포와 폐비닐을 용융시켜 혼합한 재생수지(2)를 1차로 사출성형하여 경계블록(6)을 제조한 후 그 위에 색소를 넣어 압출한 폐비닐 수지(4)를 다시 얹어 2차로 사출성형함으로써 경계블록(6) 외관을 사용자가 원하는 색상으로 제조할 수 있는 것이며, 경계블록(6) 외관이 플라스틱 재질로 되어 있어 충격에 의한 부분파손에도 안전해진다.As described above, the recycled resin (2) melted and mixed with the waste nonwoven fabric and waste vinyl was first injection molded to manufacture the boundary block (6), and then, the dye was put thereon, and the extruded waste vinyl resin (4) was placed again. By injection molding, the exterior of the boundary block 6 can be manufactured in a color desired by the user, and the exterior of the boundary block 6 is made of plastic, so that it is safe even in case of partial damage due to impact.

본 발명의 실시 예로서 상기 폐비닐은 폴리에틸렌필름일 수 있다.As an embodiment of the present invention, the waste vinyl may be a polyethylene film.

제조된 경계블록(6)은 도 5에 도시한 바와 같이 시공시 하부에 콘크리트(20)를 타설한 후 경계블록(6)을 상부에서 눌러 시공하게 되며, 경계블록(6)의 내측에 격벽형태로 형성된 공간부(8)를 통해 콘크리트(20)가 유입되어 경화되면서 본 발명의 경계블록(6)과 콘크리트(20)가 접착된다.The manufactured boundary block 6 is constructed by placing the concrete 20 at the lower side during construction as shown in FIG. 5, and then pressing the boundary block 6 from the upper side, and forming a partition wall inside the boundary block 6. The concrete block 20 and the concrete 20 of the present invention are bonded while the concrete 20 is introduced and cured through the space 8 formed as a portion.

본 발명의 경계블록(6)은 주성분이 폴리에스테르로서 이는 콘크리트(20)와의 접착력이 우수하여 경계블록(6)의 시공시에 하부에 타설된 콘크리트(20)와 견고히 고정됨에 따라 시공성도 우수한 것이다.The boundary block 6 of the present invention is a polyester as the main component is excellent in adhesive strength with the concrete 20 it is also excellent in workability as it is firmly fixed to the concrete 20 placed in the lower portion during the construction of the boundary block (6) .

또한, 경계블록(6)의 내측에는 시공시 타설된 콘크리트(20)가 공간부(8)로 유입되게 하여 경화된 후 걸림될 수 있는 걸림턱(10)을 형성할 수 있으며, 콘크리트(20)가 경화된 후 걸림턱(10)에 걸림에 따라 경계블록(6)이 쉽게 이탈하지 않고 콘크리트(20)와 견고하게 시공될 수 있는 것이다.In addition, the inside of the boundary block 6 may be formed to the locking jaw 10 that can be caught after hardened by allowing the concrete 20 poured during construction to enter the space (8), the concrete 20 After hardening, the boundary block 6 may be firmly installed with the concrete 20 without being easily detached as the hooking jaw 10 is caught.

상기 걸림턱(10)은 경계블록(6) 내부 공간부(8)에 빙둘러 형성될 수 있다.The locking jaw 10 may be formed around the inner space 8 of the boundary block 6.

더욱이 부직포에 포함된 흙은 제조시 경계블록(6)의 비중이 높아져 내구성이 높아지며, 본 발명의 실시 예에서 사용하는 수입 일본산 PO(Polyolefin, 폴리올레핀) 필름에 포함된 유리성분도 경계블록(6)의 강도를 높일 수 있는 효과가 있는 것이다.Furthermore, the soil contained in the nonwoven fabric has a higher specific gravity of the boundary block 6 during manufacture, thereby increasing durability, and the glass component contained in the imported Japanese PO (Polyolefin, polyolefin) film used in the embodiment of the present invention also has a boundary block (6). The effect is to increase the strength of.

이하에서는 도 6을 참조하여 본 발명의 실시 예에 따른 경계블록(6)의 제조방법을 설명한다.Hereinafter, a method of manufacturing the boundary block 6 according to the embodiment of the present invention will be described with reference to FIG. 6.

보온용으로 사용되는 농사용 부직포는 주성분이 폴리프로필렌과 폴리에스테르로 이를 200~210℃의 온도로 1차 용융압출을 한다.Agricultural nonwoven fabric used for keeping warm is mainly composed of polypropylene and polyester, which is first melt-extruded at a temperature of 200 ~ 210 ℃.

이때, 부직포 외부의 주성분인 폴리프로필렌 수지의 용융흐름 지수가 높아 부직포의 주성분인 폴리에스테르 수지에 완전히 혼합되지 않고 분산되며, 이와 함께 부직포 속의 흙이나 먼지, 성분이 다른 폴리프로필렌 수지가 함유되어 있어 인장력이 떨어지고 충격에 쉽게 파손된다.At this time, the melt flow index of the polypropylene resin, which is the main component outside the nonwoven fabric, is high, so that it is dispersed without being completely mixed with the polyester resin, which is the main component of the nonwoven fabric, and together with the polypropylene resin having different soil, dust, and components in the nonwoven fabric, the tensile force is increased. It falls and is easily broken in shock.

이를 보완하기 위해 1차 용융한 폐부직포 수지와 농업용 하우스에 사용되는 폐비닐 수지(4)를 혼합하여 재생수지(2)를 제조한다.In order to compensate for this, the recycled resin 2 is manufactured by mixing the first molten waste nonwoven resin and waste vinyl resin 4 used in an agricultural house.

상기 폐비닐 수지(4)는 폴리에틸렌 필름소재로 폐부직포 수지의 인장력과 충격강도를 향상시켜주게 된다.The waste vinyl resin 4 is a polyethylene film material to improve the tensile strength and impact strength of the waste nonwoven resin.

폐부직포와 폐비닐은 6~8:2~4의 중량비로 용융혼합하여 재생수지(2)를 제조하게 되며, 혼합된 재생수지(2)는 금형(12a)(12b)에 넣어 사출성형하여 경계블록(6)을 제조한다.Waste nonwoven fabric and waste vinyl are melt mixed at a weight ratio of 6-8: 2-4 to produce recycled resin (2), and the mixed recycled resin (2) is injected into molds (12a) (12b) and bounded by injection molding. Manufacture block 6.

이때, 도 4에 도시한 바와 같이 재생수지(2)를 금형(12a)(12b)에 넣어 사출성형 전에 롤러에 투입하여 넓은 판형태로 성형하여 금형(12a)(12b)위에 놓게 된다.At this time, as shown in FIG. 4, the recycled resin 2 is put into the molds 12a and 12b, and put into a roller before injection molding to be molded into a wide plate shape and placed on the molds 12a and 12b.

폐부직포만을 사용하여 경계블록(6)을 제조하게 되면 충격강도와 인장강도가 저하되어 쉽게 파손될 수 있으며, 폐비닐만 사용하게 되면 온도변화에 의한 팽창으로 변형 등의 하자가 발생할 수 있는 것이다.When the boundary block 6 is manufactured using only the waste nonwoven fabric, impact strength and tensile strength may be lowered, and thus it may be easily broken. If only waste vinyl is used, defects such as deformation may occur due to expansion due to temperature change.

본 발명에서는 폐부직포 또는 폐비닐을 단독으로 재활용하여 경계블록(6)을 제조할 경우의 문제점을 해결하여 물리적인 강도, 콘크리트(20)와의 혼합성, 변형이 없는 장점 등의 효과를 가지는 것이다.In the present invention to solve the problem in the case of manufacturing the boundary block 6 by recycling the waste nonwoven fabric or waste vinyl alone, it has the advantages of physical strength, mixing with the concrete 20, the advantage of no deformation.

폐부직포와 폐비닐을 용융 혼합한 재생수지(2)를 이용하여 1차로 경계블록(6)을 사출성형한 후에는 그 위 즉, 도로에 설치시 외부로 노출되는 외부층은 색소가 혼합된 폐비닐 수지(4)를 2차로 사출성형할 수 있다.After injection molding the boundary block 6 first by using the recycled resin 2 melt-mixing the waste nonwoven fabric and waste vinyl, the outer layer exposed to the outside when installed on the roadway is a waste of mixed pigment. The vinyl resin 4 can be injection molded secondary.

2차로 사출성형되는 폐비닐 수지(4)에는 색상을 갖도록 색소를 혼합함으로써 제조된 경계블록(6)의 외관이 다양한 색상을 가질 수 있도록 하면서 경계블록(6)의 외면이 플라스틱 재료로 구성됨에 따라 외부 충격에 의한 경계블록(6)의 파손을 방지하면서 안전사고도 방지할 수 있다.As the outer surface of the boundary block 6 is made of a plastic material, the waste vinyl resin 4 which is second injection molded can have various colors in appearance of the boundary block 6 manufactured by mixing a pigment to have a color. Safety accidents can be prevented while preventing damage of the boundary block 6 due to external impact.

사출성형된 경계블록(6)은 설치시 하부에 콘크리트(20)를 타설한 후 그 위에서 눌러 콘크리트(20)가 경계블록(6)에 형성된 공간부(8)로 유입되도록 하여 시공하게 된다.The injection molded boundary block 6 is constructed by placing concrete 20 in the lower part during installation and pressing the concrete 20 therein so that the concrete 20 flows into the space 8 formed in the boundary block 6.

본 발명은 재생수지(2)의 주성분중 하나인 폴리에스테르 화이버는 콘크리트(20)와 접착력이 우수하여 콘크리트(20)경화 후 경계블록(6)이 이탈하지 않고 견고히 고정될 수 있다.According to the present invention, polyester fiber, which is one of the main components of the recycled resin 2, is excellent in adhesive strength with the concrete 20, so that the boundary block 6 may be firmly fixed after the concrete 20 is hardened.

즉, 도로에 설치시 저면부가 도로면에 접하는 내부층을 이루는 재생수지(2)의 성분 중 부직포의 주성분인 폴리프로필렌과 폴리에스테르 화이버 중 폴리에스테르 화이버는 콘크리트와 접착이 잘되므로 인해 경계블록(6)를 도로에 설치시 경계블록(6)이 도로에 더욱더 안정적으로 고정설치될 수 있는 것이다.That is, the polypropylene and the polyester fiber of the polyester fiber, which is the main component of the nonwoven fabric, among the components of the recycled resin 2 forming the inner layer where the bottom part is in contact with the road surface when it is installed on the road, the boundary block (6). ) Is installed on the road the boundary block (6) is to be more securely installed on the road.

또한, 이때 경계블록(6)에 형성된 공간부(8)에는 내측으로 밀려들어오는 콘크리트(20)가 경화된 후 이탈하지 않도록 하는 걸림턱(10)이 형성되어 있어 설치된 경계블록(6)의 내구성도 높이게 된다.In addition, at this time, the space portion 8 formed in the boundary block 6 is formed with a latching jaw 10 to prevent the concrete 20 coming inward from being hardened and then detached, so that the durability of the installed boundary block 6 is also provided. Raised.
