폐글라스울을 재활용한 보도블럭 및 제조방법{Waste Glass Wool Recycling Sidewalk Block and Manufacturing Method}Sidewalk block and manufacturing method recycling waste glass wool {Waste Glass Wool Recycling Sidewalk Block and Manufacturing Method}

본 발명은 폐글라스울을 재활용한 보도블럭에 관한 것으로서, 입경이 서로 다른 골재가 사용된 상부층과 하부층으로 구성되며, 강도와 투수성 확보와 함께 폐기물 재활용의 효과를 거둘 수 있는 것을 특징으로 한다.The present invention relates to a sidewalk block recycled waste glass wool, and is composed of an upper layer and a lower layer using aggregates having different grain sizes, and is characterized in that it can achieve the effect of recycling waste as well as securing strength and permeability.

일반적으로 글라스울(glass wool) 또는 유리섬유(glass fiber)는 규산염을 주성분으로 하는 유리를 용융ㆍ가공하여 섬유 모양으로 가공한 것을 말하는데, 글라스 파이버(glass fiber)라고도 한다.In general, glass wool or glass fiber refers to a product obtained by melting and processing glass containing silicate as a main component and processing it into a fiber shape, which is also referred to as glass fiber.

이러한 글라스울 또는 유리섬유는 가볍고, 내열성, 내식성, 내습성, 단열성, 흡음성 등이 우수할 뿐만 아니라, 녹슬지 않으며, 열에 대한 변형이 적으며, 가공하기 쉽다는 특징이 있다. Such glass wool or fiberglass is lightweight, has excellent heat resistance, corrosion resistance, moisture resistance, heat insulation, sound absorption, etc., is not rusted, has little deformation against heat, and is easy to process.

또한 글라스울 또는 유리섬유의 지름이 가늘수록 유연성이 증가하는 특성이 있기 때문에 강화 플라스틱 원료, 전기 절연재, 건축자재, 선박의 몸체, 스키용품, 가정용 욕조, 헬멧, 테니스 라켓, 의자, 항공기 부품, 낚싯대, 흡음(방음)재, 단열재, 장식용 직물 등 매우 다양한 산업분야에서 널리 활용되고 있다.In addition, as the diameter of glass wool or glass fiber increases, flexibility increases as the diameter of glass wool or glass fiber increases. Therefore, it is used as a raw material for reinforced plastics, electrical insulation materials, building materials, ship bodies, ski supplies, household bathtubs, helmets, tennis rackets, chairs, aircraft parts, and fishing rods. It is widely used in a wide variety of industries, such as sound absorbing (soundproofing) materials, insulation materials, and decorative fabrics.

이러한 글라스울 또는 유리섬유가 폐기될 경우 대부분 소각이나 매립에 의한 처리가 이루어지고, 이로 인하여 환경오염의 문제가 심각한데, 특히 석유화학 시설의 단열재로 사용되는 경우 3~4년 내외의 주기로 교체가 필요하여 폐기물이 지속적으로 발생하게 된다.When such glass wool or glass fiber is disposed of, it is mostly treated by incineration or landfill, which causes serious problems of environmental pollution. As a result, waste is continuously generated.

이러한 폐글라스울 또는 폐유리섬유의 재활용에 대한 연구는 국내외에서 많이 이루어지고 있는데, 특히 폐기물 재처리 공정상의 친환경성(처리공정 상의 분진과 소음 그리고 2차적 환경 유해물질 배출 등의 감소) 확보와 함께 폐기물의 재자원화 방안에 대하여 관심이 집중되고 있다.A lot of research on the recycling of waste glass wool or waste glass fiber is being conducted at home and abroad. Attention is focused on the recycling method of waste.

이하에서는 본 발명의 구체적 실시예를 첨부도면을 참조하여 보다 상세히 설명한다.Hereinafter, specific embodiments of the present invention will be described in more detail with reference to the accompanying drawings.

본 발명은 폐글라스울을 재활용한 보도블럭에 관한 것으로서, 도1에 도시된 것처럼 하부층(110)과 상부층(120)으로 구성된다.The present invention relates to a sidewalk block recycled from waste glass wool, and is composed of a lower layer 110 and an upper layer 120 as shown in FIG.

하부층(110)은 폐글라스울, 1차골재 및 시멘트로 이루어지며, 내부에 공극이 형성되어 투수성을 가진다.The lower layer 110 is made of waste glass wool, primary aggregate and cement, and has pores formed therein to have water permeability.

상부층(120)은 이러한 하부층(110)의 상부에 적층되어 함께 성형되며, 2차골재 및 시멘트로 이루어지며, 내부에 공극이 형성되어 투수성을 가진다.The upper layer 120 is laminated on top of the lower layer 110 and molded together, and is made of secondary aggregate and cement, and has pores formed therein to have water permeability.

폐글라스울은 석유화학 시설의 폐기물이나 건축이나 선박 폐기물 등에서 수거되어 미리 설정된 크기로 분쇄된 후 사용되는데, 본 발명의 구체적 실시예에서는 입경 1 내지 3 mm 로 분쇄된 것이 사용된다.Waste glass wool is used after being collected from waste from petrochemical facilities, construction or ship waste, etc. and pulverized to a preset size. In a specific embodiment of the present invention, pulverized glass wool with a particle size of 1 to 3 mm is used.

상부층(120)은 하부층과는 달리 폐글라스울이 포함되지 않으며, 하부층(110)에 사용되는 1차골재는 상부층(120)에 사용되는 2차골재에 비하여 상대적으로 입경이 크다.Unlike the lower layer, the upper layer 120 does not contain waste glass wool, and the primary aggregate used in the lower layer 110 has a relatively larger particle size than the secondary aggregate used in the upper layer 120.

1차골재는 입경 8 내지 12 mm 가 사용되며, 건축 폐기물 등을 재활용한 재생골재가 사용될 수도 있다. The primary aggregate is used with a particle diameter of 8 to 12 mm, and recycled aggregate recycled from construction waste may be used.

2차골재는 보도블록의 상부 표면을 형성한다는 것을 고려하여 재생골재를 사용하지 않으며, 입경 2 내지 3 mm 인 골재가 사용된다.Considering that the secondary aggregate forms the upper surface of the sidewalk block, recycled aggregate is not used, and aggregate having a particle size of 2 to 3 mm is used.

따라서, 상부층(120)은 하부층(110)에 비하여 상대적으로 균일하고 깔끔한 느낌을 지니게 된다.Therefore, the upper layer 120 has a relatively uniform and neat feel compared to the lower layer 110 .

아울러, 하부층(110)은 상부층(120)에 비하여 공극이 크고 투수성이 높은 구조가 되고, 이러한 구조적 특성으로 인하여 하부층(110)이 상부층(120)에 비하여 상대적으로 강도가 저하될 수 있는데, 폐글라스울이 강도 보강 역할을 하면서 이러한 문제점을 최소화하게 된다.In addition, the lower layer 110 has a structure with larger pores and higher permeability than the upper layer 120, and due to this structural characteristic, the lower layer 110 may have a relatively lower strength than the upper layer 120. Glass wool serves to reinforce the strength and minimizes these problems.

하부층(110)의 조성비를 보면, 시멘트 100중량부에 대하여 폐글라스울 15 내지 25중량부, 1차골재 450 내지 550중량부, 물 5 내지 15중량부의 비율로 혼합된다.Looking at the composition ratio of the lower layer 110, 15 to 25 parts by weight of waste glass wool, 450 to 550 parts by weight of primary aggregate, and 5 to 15 parts by weight of water are mixed with respect to 100 parts by weight of cement.

상부층(120)의 조성비를 보면, 시멘트 100중량부에 대하여 2차골재 300 내지 350중량부, 물 5 내지 15중량부의 비율로 혼합된다.Looking at the composition ratio of the upper layer 120, 300 to 350 parts by weight of secondary aggregate and 5 to 15 parts by weight of water are mixed with respect to 100 parts by weight of cement.

시멘트의 종류는 특별히 한정되지 않으며, 이미 상용화되어 있는 일반적인 백시멘트, 포틀랜드 시멘트 등에서 선택될 수 있다.The type of cement is not particularly limited, and may be selected from general white cement, Portland cement, etc., which are already commercially available.

하부층(110)을 구성하는 하부 조성물과 상부층(120)을 구성하는 상부 조성물은 각각 별개로 혼합된 후 순차적으로 성형틀(310)에 투입되는데, 하부 조성물을 먼저 성형틀(310)에 투입한 후 1차 가압판(210)으로 하부 조성물의 상부를 진동 압착하여 다지는데, 1차 가압판(210)의 표면에 파형 또는 요철 형상이 구비되어 있는 경우 하부 조성물의 상부면도 그에 따라 파형 또는 요철 형상으로 다져진다.The lower composition constituting the lower layer 110 and the upper composition constituting the upper layer 120 are separately mixed and then sequentially put into the mold 310. The lower composition is first put into the mold 310 and then The upper part of the lower composition is compacted by vibration pressing with the first pressing plate 210. When the surface of the first pressing plate 210 has a corrugated or concave-convex shape, the upper surface of the lower composition is also compacted in a corrugated or concave-convex shape accordingly. .

하부 조성물의 상부면에 파형 또는 요철 형상이 형성된 후 상부 조성물을 투입하고 2차 가압판(220)으로 진동 압착하여 다지고, 함께 양생하면 상부층(120)과 하부층(110)의 경계면은 파형 또는 요철 형상으로 서로 맞물리는 구조로 하나의 보도블록이 완성되어 서로 다른 조성물로 이루어진 상부층(120)과 하부층(110)의 경계에서 결합력을 극대화시킬 수 있다.After a corrugated or concave shape is formed on the upper surface of the lower composition, the upper composition is introduced, vibrated and compacted with the secondary pressing plate 220, and cured together to form a corrugated or concave-convex shape on the interface between the upper layer 120 and the lower layer 110. One sidewalk block is completed with a structure that interlocks with each other to maximize the bonding force at the boundary between the upper layer 120 and the lower layer 110 made of different compositions.

수직통공(130)은 하부층(110)의 상부면에서 시작하여 하부층(110) 내부를 수직으로 관통하여 상부층(120)의 상부와 연결되어 보도블록의 투수 성능을 향상시키는 역할을 한다.The vertical through hole 130 starts from the upper surface of the lower layer 110 and vertically penetrates the inside of the lower layer 110 and is connected to the upper portion of the upper layer 120 to improve the water permeability of the sidewalk block.

이러한 수직통공(130)은 상부 조성물을 성형틀(310)에 투입한 후 2차 가압판(220)으로 진동 압착하는 과정에서 형성되는데, 2차 가압판(220)에는 수직통공(130)에 대응하는 형상과 크기의 돌기(225)가 형성되어 있기 때문이다.The vertical through hole 130 is formed in the process of vibration compression with the secondary pressure plate 220 after the upper composition is put into the molding mold 310. The secondary pressure plate 220 has a shape corresponding to the vertical through hole 130. This is because protrusions 225 having a size of and are formed.

수직통공(130)의 직경이나 수량 등은 보드블록의 크기를 고려하여 적절히 선택될 수 있다.The diameter or quantity of the vertical through holes 130 may be appropriately selected in consideration of the size of the board block.

하부층(110)과 상부층(120)으로 구성되는 보도블럭은 도1에 도시된 것처럼 평면 형상은 전체적으로 정사각형이 되거나, 별도로 도시하지 않았으나 일측 변의 길이가 타측 변의 길이보다 긴 직사각형이 될 수도 있다.As shown in FIG. 1, the sidewalk block composed of the lower layer 110 and the upper layer 120 may have a square shape as a whole, or a rectangle with one side longer than the other side, although not shown separately.

도2에는 본 발명의 다른 구체적 실시예로서, 정사각형의 각 변 중앙부에 측면홈(140)이 구비되는 경우를 도시한다.2 shows a case in which side grooves 140 are provided at the center of each side of a square as another specific embodiment of the present invention.

이러한 측면홈(140)은 정사각형의 내부를 향하여 미리 설정된 폭과 길이만큼 절개되는데, 측면홈의 바닥 길이(2a)는 측면홈(140)이 형성되지 않은 좌우 양측 모서리 부위 길이(a)의 합과 동일하여 이웃하는 보도블록의 측면홈(140) 위치가 일치되도록 배치하면 서로 마주 보는 측면홈(140) 사이에 공간으로 배수 통로(150)가 형성되어 보도블록을 설치할 때 포설하는 모래와 같은 충진재로 그 공간이 채워지더라도 투수 성능을 어느 정도 확보할 수 있고, 측면홈(140)에 이웃하는 보도블록의 모서리 부위가 끼워지도록 엇갈리게 배치하면 이웃하는 보도블록이 서로 맞물리는 구조가 되어 상호 결착 상태를 안정적으로 유지할 수 있다. These side grooves 140 are incised by a predetermined width and length toward the inside of the square. When the side grooves 140 of neighboring sidewalk blocks are the same and arranged to match, a drainage passage 150 is formed as a space between the side grooves 140 facing each other, and a filler such as sand laid when installing a sidewalk block is used. Even if the space is filled, the water permeability can be secured to some extent, and if the side grooves 140 are staggered so that the corners of neighboring sidewalk blocks are inserted, the neighboring sidewalk blocks are interlocked with each other, resulting in a stable mutually bound state. can be maintained as
