Description
본 발명은 이중 고무 보도블럭에 관한 것으로, 폐타이어 재활용 이중 고무보도블럭에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double rubber sidewalk block and to a waste tire recycling double rubber sidewalk block.
차량의 급격한 증가는 인간에게 편리함을 가져다 주는 동시에 폐타이어 처리라는 환경적 문제를 동반하게 되었는바, 정부에서도 폐타이어를 폐기물 예치금 부과품목으로 지정하는 등 자구책을 강구하고 있으나 실효를 거두지 못하고 있는 실정이다.The rapid increase in vehicles has brought human convenience and environmental problems such as disposal of waste tires, and the government has been making self-responsibility measures such as designating waste tires as waste deposit items. .
폐타이어 재활용의방안이 추구할 방법이라는 것은 논할 여지가 없으나, 이에 따른 경제성문제 및 기술개발의 부진으로 어려움이 많았다.It is indisputable that the method of recycling waste tires will be pursued, but it was difficult due to economic problems and sluggish technology development.
본 발명은 이와 같이 환경부분에서 문제가 되면서도 늘어만 가는 폐타이어를 재활용하여 고무 보도블럭을 제조, 공급하므로써 체육시설 및 공공시설등에 보급하여, 환경문제 해결과 동시에 국민보건증진에 기여함을 목적으로 한다. 특히 장애자용 점자블럭 및 유도블럭의 제조에 있어서 상층이 노란색 등의 유색을 원하기 때문에 종래의 폐타이어만으로는 까만 색상을 유색으로 바꾸기에는 한계가 있고, 또한 종래의 특허 제172473호(본원출원인의 발명)에 기술한 폐EPDM고무분말을 상층부에 사용시 고무 보도블럭으로서 때가 많이 타고 외관상의 문제점으로 인하여 이에 개선이 요구되였다. 일반적으로, 고무 보도블럭은, 종래의 보도블럭은 무기재료의 보도블럭으로 깨어지기 쉽고, 균열이 잘 일어나 미관상 좋지 않았고, 중량관계로 작업이 용이하지 않은 단점이 있었으며, 일반적으로 무기재료에 의한 보도블럭에 비해 폐타이어를 이용한 보도블럭이 인체의 피로도 감소와 마소성이 우수하다고 알려져 있다.The present invention aims to contribute to the improvement of public health and the improvement of public health by distributing it to sports facilities and public facilities by manufacturing and supplying rubber sidewalk blocks by recycling waste tires that are increasing in number in the environment. . In particular, in the manufacture of braille blocks and induction blocks for the handicapped, there is a limit to changing the black color to the colored color only with the conventional waste tires, and the conventional patent No. 172473 (the invention of the present applicant). When the waste EPDM rubber powder described in the above) is used in the upper layer, it is required to improve due to the appearance problem because it is often worn as a rubber press block. In general, the rubber sidewalk block, the conventional sidewalk block is easy to be broken by the sidewalk block of the inorganic material, the cracks were not good because of the aesthetic appearance, there was a disadvantage that the work is not easy due to the weight relationship, in general, the sidewalk by the inorganic material Compared to the block, the sidewalk block using waste tire is known to reduce fatigue and wear resistance of the human body.
폐타이어 분쇄물을 이용한 보도블럭으로는 폐타이어를 분쇄한 분쇄물에 접착제를 90∼95% : 10∼5%의 비율로 가하고 혼합한 후 열풍을 가하여 결합요홈을 갖도록 한 직사각형태의 내습성, 내기후성, 내무식성과 내마모성이 우수한 체육관, 수영장 , 조깅로 설치용 보도블럭이 실용화 되고 있다(공개 실용신안공보, 공개번호제95 -6495호 참조). 또한, 실내 장식용 고무재 매트의 제조방법으로서, 폐타이어나 고무제품을 분쇄하여 1.5∼3.5mm와 1.5mm이하를 갖는 원료를 35-60:60-35%로 하여 혼합기에 투입하고, 전체 재료에 대하여 아크릴계페인트 잉크를 90-95:10-5%로 하여 회전, 착색시키고, 착색재료에 대해 가황고무접착제를 85-95:15-5%로하여 회전, 흡착시키고, 열풍기류로서 성형 제조하여 매트를 제조하는 방법이 알려져 있다 (특허공보, 공고번호 제95-173호 참조).As the sidewalk block using the waste tire crushed product, the rectangular tire moisture resistance which has adhesive groove is added to the crushed crushed waste tire in a ratio of 90 to 95%: 10 to 5%, mixed, and then hot air is applied to the crushed product. Gymnasiums, swimming pools, and jogging paths with sidewalk blocks with excellent weather resistance, erosion resistance and abrasion resistance have been put into practical use (see Published Utility Model Publication, Publication No. 95-6495). In addition, as a manufacturing method of the rubber mat for upholstery, waste tires or rubber products are pulverized, and raw materials having 1.5 to 3.5 mm and 1.5 mm or less are made into 35-60: 60-35%, and the mixture is put into the whole material. Rotate and color the acrylic paint ink at 90-95: 10-5%, rotate and adsorb the vulcanized rubber adhesive at 85-95: 15-5% with respect to the colored material, and form and manufacture it as a hot air stream. A method of producing is known (see Patent Publication, Publication No. 95-173).
그러나, 이는 상하 전체가 균질한 형태의 매트를 얻을수 있는 것이어서 장기간 경과시 탄성의 저하 및 색상변상 등에 문제가 있지는 마찬가지였다.However, this is because it is possible to obtain a mat of a homogeneous form of the entire upper and lower sides, so that there is no problem such as deterioration of elasticity and color change over time.
이와 같이 폐타이어는 분말화하여 각종 고무제품이나 건축자재, 고무아스팔트, 브레이크 라이닝에 사용되고 있으며, 외국에서는 보도블럭, 스포츠센타트랙, 테니스코트등에 사용되고 있다.(이덕수, 최재성; 폐타이어의 효율과 그 전망. pp 60∼65: 김진광, 폐타이어를 이용한 고무아스팔트포장, 타이어고무, pp 10∼19. 1990: K. Nishimora, Paper of Korean-Japanes Rubbere Techonology Symposium, Recycling of used Tires in Japan. 24-33, 1992 참조)As such, waste tires are powdered and used for various rubber products, construction materials, rubber asphalt, brake linings, and foreign countries are used for sidewalk blocks, sports center tracks, tennis courts, etc. (Duk-Soo Lee, Jae-Sung Choi; Pp. 60-65: Jin-Kwang Kim, Rubber Asphalt Packaging Using Tires, Tire Rubber, pp 10-19.1990: K.

이하 하층부와 상층부 및 보도블럭으로 나누어 설명한다.Hereinafter, the description will be divided into a lower layer, an upper layer, and a sidewalk block.
(하층부 구성)(Underlayer configuration)
본 발명의 하층부에 사용되는 폐타이어 분말은 분말입도크기가 0.01∼2.5mm 범위내에 있는 것이 좋은데, 만약 1mm이상의 크기의 입도분말인 경우에는 고분자 바인더를 사용하는 것이 바람직하고 1mm이하의 입도분말인 경우에는 고분자바인더의 사용량이 증가되어 경제적이지 못하다. 또한 2.5mm이상에서는 공극에 의하여 물성저하의 문제점이 따르게 된다.The waste tire powder used in the lower layer of the present invention preferably has a powder particle size in the range of 0.01 to 2.5 mm. In the case of a particle size powder of 1 mm or more, it is preferable to use a polymer binder and a particle size powder of 1 mm or less. There is an increase in the amount of polymer binder is not economical. In addition, in the case of 2.5mm or more, there is a problem of deterioration of physical properties due to voids.
하층부에 사용되는 고분자 바인더로는 폴리우레탄을 사용하며, 폐타이어 분말 100중량부당 5∼20중량부가 좋다.Polyurethane is used as the polymer binder used in the lower layer, and 5 to 20 parts by weight per 100 parts by weight of the waste tire powder is good.
한편, 고분자 바인더 대신에 가교제로 황을 사용할 수 있으며, 그 사용량은 폐타이어 분말 100중량부당 5∼10중량부이면 족하고, 만일 5중량부 미만으로 첨가되는 경우 미가황되는 문제점이 발생되고 10중량부 초과시에는 과가황의 문제점이 발생되어 보도블럭의 물성을 떨어 뜨리게 된다.Meanwhile, sulfur may be used as a crosslinking agent instead of the polymer binder, and the amount of sulfur may be used in an amount of 5 to 10 parts by weight per 100 parts by weight of the waste tire powder. When exceeded, the problem of overvulcanization occurs, which degrades the physical properties of the sidewalk block.
또한, 가류촉진제로는 테트라메틸티우람디설파이드(Tetramethyl thiuram disulfide : TMTD)가 바람직하게 사용될 수 있으며, 벤조티아질 디설파이드(Benzothiazyl disulfide : DM), 엔-시클로헥실-2-벤조티아졸-셀펜아미드(N-cyclohexyl-2-benzothiazole-sulfenamide:CZ)을 대체 사용할수 있으며, 그 사용량은 2∼3중량부가 바람직하다. 부족시에는 성형상에 미가황을 발생시킬수 있고, 초과될 경우 과가황을 초래할수 있다.In addition, tetramethyl thiuram disulfide (TMTD) may be preferably used as the vulcanization accelerator, benzothiazyl disulfide (DM), en-cyclohexyl-2-benzothiazole-selpenamide ( N-cyclohexyl-2-benzothiazole-sulfenamide (CZ) can be used instead, and its amount is preferably 2-3 parts by weight. In case of shortage, unvulcanization may occur in molding, and if exceeded, overvulcanization may occur.
그 밖에 접착력을 향상시키기 위하여 나프탄(naphthane)계 오일 5∼10ml, 송진 5∼10중량부, 디에틸렌글리콜(DEG) 15∼20ml를 사용하는데, 송진의 양이 상기 범위를 벗어날 시에는 물성의 저하를 초래하게 되고(도 1 참조), DEG는 필요에 따라 가하지 않을 수도 있는데 바람직한 물 성치를 염두에 둔다면 추천할 수 있다.In addition, 5-10 ml of naphthane oil, 5-10 parts by weight of rosin, and 15-20 ml of diethylene glycol (DEG) are used to improve adhesion. This will lead to degradation (see Figure 1), and DEG may not be added as needed, which can be recommended if the desired physical properties are in mind.
가교제와 가류촉진제의 함유량이 본 발명의 물성에 미치는 영양을 실험한 그래프를 도2 및 도3에 나타내였다.2 and 3 show graphs of experiments on the nutrition of the content of the crosslinking agent and the vulcanization accelerator on the physical properties of the present invention.
하층부 구성에 있어 탈가교된 재생고무를 이용하는 경우, 재생고무 100중량부에 가교제로서 황 5∼10중량부, 가류촉진제 2∼3중량부, 충진제로서 탄산칼륨(CaCO3)과 카본 블랙을 20∼200중량부를 사용하여 보도블럭을 얻을 수 있고, 또는 폐타이어 분말에 재생고무를 바인더로서 1:2-5 혼합, 사용할 수도 있다.In the case of using the decrosslinked regenerated rubber in the lower layer structure, 5 to 10 parts by weight of sulfur as a crosslinking agent, 2 to 3 parts by weight of vulcanization accelerator, and 20 to 20 parts of potassium carbonate (CaCO 3 ) and carbon black as fillers. A press block may be obtained using 200 parts by weight, or recycled rubber may be mixed 1: 2-5 as a binder in the waste tire powder.
(상층부구성)(Upper layer composition)
하층부위에 구성되는 상층부는 에틸렌 프로필렌고무(EPDM) 또는 니트릴고무 (NBR)를 주성분으로하고, 에틸렌프로필렌고무를 사용하는 경우 원하는 색상의 안료 1∼3중량부와 이를 성형시키기위한 가교제, 가류촉진제, 가공조제, 가공오일 및 충진제 등으로 구성되며, 상층부 구성중 안료는 무기안료와 유기안료 모두 사용 될수 있는데, 무기안료는 값이 저렴한 대신에 색상이 변한다는 결점이 있고, 유기안료는 가격이 비싼 대신에 생상의 안정성이 보장된다.The upper part of the lower part is composed mainly of ethylene propylene rubber (EPDM) or nitrile rubber (NBR), and when ethylene propylene rubber is used, 1-3 parts by weight of a pigment of a desired color and a crosslinking agent, a vulcanization accelerator, and a processing for molding the same It is composed of preparation, processing oil and filler.In the upper layer, pigment can be used both inorganic pigment and organic pigment.Inorganic pigment has the disadvantage of changing color instead of low price, and organic pigment has high price Birth stability is guaranteed.
가교제로는 상층부에서와 같이 황의 사용이 바람직하며 2∼7중량부가 사용되고, 과산화물 가교제의 사용도 가능하다.As the crosslinking agent, sulfur is preferably used as in the upper layer portion, 2 to 7 parts by weight is used, and peroxide crosslinking agent may be used.
가류촉진제로는 벤조티아질디설파이드(DM), 디펜타메틸렌 티우람트리설파이드(Dipenta methylene thiuram trisulfide:TRA)등을 사용할 수 있으며, 1∼5중량부가 바람직하며, 이 범위를 벗어나면 가교시스템에 불안정성이 초래되어, 부족하면 미가황상태가 나타나고 과하면 과가황상태가 나타나 성형상의 문제점과 물성이 저하된다.As a vulcanization accelerator, benzothiazyl disulfide (DM), dipentamethylene thiuram trisulfide (TRA), etc. may be used, and 1 to 5 parts by weight is preferable, and if it is out of this range, it is unstable to the crosslinking system. This results in an unvulcanized state when insufficient, and an excessively vulcanized state when excessive, resulting in deterioration of molding problems and physical properties.
기타 가공조제로서는 스테아린산 1∼2중량부, 산화아연 3∼7중량부, 왁스 3∼7중량부 등을 혼합하여 5∼10중량부가 되도록 첨가한다. 충진제로서 화이트카본과 CaCO3를 100∼200중량부를, 그리고 가공 oil 20∼30ml를 가한다.As other processing aids, 1 to 2 parts by weight of stearic acid, 3 to 7 parts by weight of zinc oxide, 3 to 7 parts by weight of wax, etc. are mixed and added so as to be 5 to 10 parts by weight. As a filler, 100 to 200 parts by weight of white carbon and CaCO 3 and 20 to 30 ml of processed oil are added.
EPDM 컴파운드는 내후성이 우수하여 색상의 안정성이 있으나 점착성이 좋지 못하여 니트로고무(NBR) 컴파운드를 사용할 수도 있으며, 니트로 고무(NBR)를 사용하는 경우에는, NBR고무 100중량부, 화이트카본 30∼50중량부, 산화아연 3∼5중량부, 스테아린산 1∼2중량부, 가교제 7∼12중량부, 안료 3∼5중량부 및 가류촉진제 1∼2중량부로 구성한다.EPDM compound has excellent weather resistance and color stability but poor adhesion. Nitro rubber (NBR) compound may be used. When Nitro rubber (NBR) is used, 100 parts by weight of NBR rubber and 30 to 50 weight of white carbon And 3 to 5 parts by weight of zinc oxide, 1 to 2 parts by weight of stearic acid, 7 to 12 parts by weight of crosslinking agent, 3 to 5 parts by weight of pigment, and 1 to 2 parts by weight of vulcanization accelerator.
(보도블럭)(Press block)
본발명의 고모보도블럭은 상층부와 하층부로 구성된 보도블럭으로, 특히, 상층부와 하층부의 두께의 비는 1:2-5의 비율이 되도록 구성하는 것이 바람직하다(도 4참조).The high footpath block of the present invention is a sidewalk block composed of an upper layer and a lower layer, and in particular, the ratio of the thickness of the upper layer and the lower layer is preferably configured to be 1: 2-5 (see Fig. 4).
본 발명에서 경제성을 높이기 위하여, 하층부의 구성을 고분자바인더 대신에 가교제를 사용하여 고분자 바인더를 배제하는 방법으로 실행하여 성형할 수도 있으며, 재생고무를 binder로 하여 폐타이어 분말과 혼합한 다음 성형가공 할수도 있다. 또한 하층부 중심부에 벽돌 또는 나무 같은 물질을 삽입하여 성형하여 제조원가를 줄이는 방법을 택하였다. 벽돌과 나무에는 구멍이 있는 것을 사용하는 것이 바람직한데, 그 이유는 구멍사이로 고무가 침입하여 접착력을 좋게하기 위함이다. 이 방법은 하층부 두께가 두꺼워지면 성형시간 및 성형이 안되는 문제점을 해결할수 있는 장점도 있다. 또한, 경제성을 위하여 벽돌이나 나무외에도 돌을 분산하여 혼합하는 방법으로 구성될 수도 있다(도 5a 및 도 5b참조).In order to increase the economic efficiency in the present invention, the lower layer may be formed by performing a method of excluding a polymer binder by using a crosslinking agent instead of a polymer binder, and may be molded after mixing with waste tire powder using recycled rubber as a binder. There is also. In addition, by inserting a material such as brick or wood in the center of the lower layer was selected to reduce the manufacturing cost. It is advisable to use holes with bricks and trees, because the rubber intrudes through the holes to improve adhesion. This method also has the advantage of solving the problem that the molding time and the molding is not thick when the lower layer thickness is thick.

본 발명에 따라 제조된 폐타이어 재활용 고무 성형품인 이중보도블럭은, 종래의 사용되던 폐타이어 재활용 보도블럭의 단점인 색상이 우아하지 못하고 내후성이 약하다는 결점을, 내후성이 우수한 EPDM컴파운드나 NBR컴파운드로 상층부로 구성하므로서 단일품 EPDM이나 NBR로 구성된 성형품보다 경제성인 면에서 우월하며, 폐타이어 고무 분말이나 재생고무로서 이루어진 고무보도블럭보다는 유색색상을 지니는 제품으로 색상의 우아함을 지니게 하였고, 장애자용 고무보도블럭을 얻을수 있다는 장점이 있다.The double sidewalk block, which is a waste tire recycled rubber molded article manufactured according to the present invention, has the drawback that the disadvantages of the conventional waste tire recycled press block are that the color is not elegant and the weather resistance is weak. The EPDM compound or the NBR compound having excellent weatherability As it is composed of upper layer, it is superior in terms of economical efficiency to molded products composed of single product EPDM or NBR, and it is colored with color rather than rubber foot block made of waste tire rubber powder or recycled rubber. The advantage is that you get a block.
또한, 종래의 폐EPDM 고무분말로 상층부를 구성한 제품에서 볼수 있는 때(지저분함)가 탄다는 결점을 새로운 조성의 EPDM 이나 NBR컴파운드를 사용함으로서 해결하였다.In addition, the problem of burning (dirty) when seen in a product composed of a conventional waste EPDM rubber powder has been solved by using EPDM or NBR compound of a new composition.
본 발명은 산업적으로 매우 유용한 발명임을 알수 있다.It can be seen that the present invention is an industrially very useful invention.
