Description

폐타이어를 이용한 토건재의 제조방법Manufacturing method of construction materials using waste tires

본 발명은 자동차에서 발생되는 폐타이어등을 이용하여 이를 건축재나 보도블럭 또는 아스콘의 바인더등의 토목재로 사용되게한 폐타이어를 이용한 토건재의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a civil engineering material using waste tires that are made using waste tires generated in automobiles and used as civil engineering materials such as building materials, sidewalk blocks or ascon binders.

근래들어 자동차의 보유댓수가 폭발적으로 증가하여 현재 500∼600 만대에 이르고 있어 이로부터 발생하는 폐타이어 역시 매년 막대하게 발생됨에도 불구하고 그 재 활용도가 극히 미미하여 거의가 그대로 매립되거나 소각처리하는 것이 대부분이어서 심각한 환경공해를 야기하므로서 그 처리문제가 심각한 사회문제로 대두되고 있을 뿐만 아니라 재활용 가치가 큰 합성수지가 그냥 버려지므로서 자원낭비의 비경제적인 결점이 있었다.In recent years, the number of cars owned has exploded and now reaches 5 to 6 million vehicles. The waste tires generated from these vehicles are also generated very largely every year. However, most of them are reclaimed or incinerated. Not only is the treatment problem a serious social problem by causing a serious environmental pollution, but also a waste of resources is caused by the waste of synthetic resins with high recycling value.

이러한 폐타이어에 대한 재처리 방법으로서 이를 분쇄하여 다른 성형물로 성형제조코저 하는 방법을 시도하고 있으나, 타이어의 특성상 그 내부에 강도유지용 섬유포등이 내입되어 있어 그 파쇄가 잘되지 않고 그 가소성인 재질의 특성상 분쇄가 곤란한 결점이 있어 대부분 이를 가열하여 직접 용융처리하고 있으나 이 경우 제2차 제품이 극히 불량하여 그 방법은 거의 이용되지 않고 있다.As a reprocessing method for such a waste tire, a method of crushing it and molding and manufacturing it into another molding is attempted. However, due to the characteristics of the tire, a fiber cloth for maintaining strength is incorporated therein, so that the crushing is difficult and the plastic material is not easily broken. Due to its characteristics, it is difficult to pulverize, and most of it is directly melted by heating, but in this case, the secondary product is extremely poor, and the method is rarely used.

본 발명은 폐타이어를 비롯한 각종 폐합성수지를 재생시켜 새로운 제품으로 재활용코저 발명한 것으로서 폐타이어등을 액화질소에 의해 급속 냉각시켜 이를 냉동상태에서 파쇄 및 분쇄한후 유황성분등을 중화시켜 그 입자를 각종 토건재로 이용되게한 것이다.The present invention is to invent various recycled synthetic resins including waste tires and recycle them into new products. Rapid cooling of waste tires with liquefied nitrogen, crushing and crushing them in a frozen state, neutralizing sulfur components, etc. It is intended to be used in various civil materials.

이하, 본 발명의 요지를 실시예에 의하여 상세히 설명한다.Hereinafter, the gist of the present invention will be described in detail by way of examples.

수집된 폐타이어나 폐합성수지등을 대형 3중용기에 내입한 후, 용기를 밀폐시킨 다음 액화질소를 용기내에 가득채우고 10∼15분간 경과시킨다.After the collected waste tires or waste synthetic resin are introduced into a large triple container, the container is sealed, and the liquid nitrogen is filled in the container and then passed for 10 to 15 minutes.

이때 폐타이어, 폐합성수지등은 액화질소의 자체온도 -190∼-210℃에 의해 급속냉각되어 약 -120∼130℃의 상태에 이르게 되는 것이다.At this time, the waste tire, the waste synthetic resin, etc. are rapidly cooled by the liquid temperature of -190 to -210 ° C to reach a state of about -120 to 130 ° C.

용기내의 급냉된 폐타이어를 용기에서 인출하여 냉동상태가 유지된 상태에서 이를 강한 타격이나 충격을 가하여 1차 파쇄한다.The quenched waste tire in the container is taken out of the container and subjected to a strong blow or impact while being crushed in the frozen state, and then first crushed.

이때의 폐타이어등의 온도가 상온에서 -80∼-100℃의 상태를 유지하므로 타격이나 충격을 받은 폐타이어등은 내부조직에 섬유포등이 내입되어 있더라도 이 역시 함께 냉동상태에 있으므로 균열이 심한 상태나 덩어리 상태의 조각으로 파쇄될 수 있는 것이다.At this time, since the temperature of the waste tires is maintained at -80 to -100 ° C at room temperature, even when the tires are hit or impacted, even if the fiber cloth is embedded in the internal tissues, they are also in the frozen state, so the cracks are severe. I can be broken into chunks.

이와 같이 균열이 심하거나 덩어리 상태로 파쇄된 조각들을 다시 용기에 넣어 위의 냉동과정을 거친후 분쇄칼이나 분쇄로울러등으로된 분쇄장치에 내입하여 회전시키므로서 2차 분쇄하여 입자상태로 미립자화 한다. 여기에서도 -80∼-100℃의 냉동상태가 유지되고 있으므로 재질의 변질없이 미립자화가 가능한 것이다.Thus, the cracked or crushed flakes are put back into the container and subjected to the above freezing process, and then crushed into a pulverizing device made of a crushing knife or crushing roller, followed by a second crushing to granulate the particles. . Here, the frozen state of -80 to -100 ° C is maintained, so that the particles can be formed without altering the material.

이와같이 성형된 입자에 상온상태에서 화이트카본 또는 규소분말을 중량대비 15∼20%를 첨가하여 혼합한뒤 나트륨용액(NaOH)으로 중화시켜 PH7∼7.5를 유지케 한다.In this way, the mixture is added by mixing 15 to 20% by weight of white carbon or silicon powder at room temperature, and then neutralized with sodium solution (NaOH) to maintain PH 7 to 7.5.

여기서 화이트카본이나 규소분말은 입자사이의 밀착도를 증가되게하고 색상을 비교적 밝게 하는데 사용되며 주로 건식재료에는 화이트카본을 사용하고 습식재료에는 규소분말을 사용한다.Here, white carbon or silicon powder is used to increase the adhesion between particles and make the color relatively bright. Mainly, white carbon is used for dry materials and silicon powder is used for wet materials.

또 나트륨용액은 원재료에 함유된 유황성분의 량에 따라 가감하며 혼합시켜 PH7-7.5가 되게하는 것이다.In addition, sodium solution is added or subtracted according to the amount of sulfur contained in the raw material to be PH7-7.5.

이와 같이 형성된 입자에 대하여 완전 건조시킨 후 이들을 접착제와 혼합시킨 후 성형코저 하는 제품의 금형틀 내에 내입하고 압축시켜 소정의 제품을 얻는 것이다.The particles thus formed are completely dried and then mixed with an adhesive, and then molded into a mold of a product to be molded and compressed to obtain a predetermined product.

본 발명의 실시예에서는 벽돌등의 건축재로 사용하기 위해, 입자에 대하여 고강도 접착제인 폴리이소시아네이트(POLYISOCYANATE ADHESIVE)의 점도를 낮추어 혼합하고 이를 벽돌형 금형틀 내에 내입한후 압력을 가하여 형성한 결과, 방수, 방음, 방풍, 방열, 방습, 부식방지등이 뛰어나고 강도가 강한 벽돌을 얻을 수 있었다.In the embodiment of the present invention, for use as a building material, such as brick, by lowering the viscosity of the polyisocyanate (POLYISOCYANATE ADHESIVE), which is a high-strength adhesive to the particles, and mixed with the particles and put them in a brick mold, and formed by applying pressure, waterproof Excellent brick strength, soundproofing, windproof, heat dissipation, moisture proof, anti-corrosion, etc. was obtained.

또한 보도블럭을 만들기 위해서는 전기한 입자를 역시 강력접착제인 이소아네이트(ISOCYANATE ADHESIVE)와 혼합하여 생산코저 하는 블럭형 금형틀 내에 넣고 압축한 결과 역시 탄력성과 유연성이 우수하며 충격에 강하여 파손되지 않고 마모율이 적음에 따라 노면 굴곡의 발생을 막아 시멘트 블럭의 약점을 보완할수 있는 보도블럭을 얻을수 있었다.In addition, in order to make the press block, the above-mentioned particles are mixed with ISOCYANATE ADHESIVE, which is also a strong adhesive, and put into a block-shaped mold to produce. Compressive results are also excellent in elasticity and flexibility. As a result, it was possible to obtain a sidewalk block that could compensate for the weakness of the cement block by preventing the occurrence of road curvature.

특히, 전기한 입자를 아스콘의 바인더로 사용하여도 매우 훌륭한 아스팔트를 제공할수 있는 것인데, 아스콘의 바인더로 사용할시는 전기한 입자를 건조한후, 이를 아스콘의 중량대비 5-8%로 첨가하는 첨가제로 혼합하여 사용케 되면 접착력이 우수하고 아스콘의 마모율도 적으며 탄력성과 유연성이 튀어나고 특히 내구성, 내열성, 내한성, 내마모성이 우수한 아스팔트를 얻을 수 있었다.In particular, it is possible to provide very good asphalt even when the above-mentioned particles are used as binders of ascone, and when used as binders of ascones, it is an additive that adds 5-8% to the weight of ascone after drying the above-mentioned particles. When used in combination, it was possible to obtain asphalt with excellent adhesive strength, low wear rate of ascon, high elasticity and flexibility, and particularly excellent durability, heat resistance, cold resistance, and abrasion resistance.

이상과 같이 본 발명은 폐타이어를 이용한 토건재의 제조방법을 제공하므로서, 매년 수만톤씩 발생되는 폐타이어를 매장하거나 연소하지 않고 처리되게하여 제2차 공해 발생의 원인을 원천적으로 제거했을뿐 아니라, 오히려 이를 방수, 방음, 방풍, 방열, 방습, 부식방지 효과가 뛰어난 건축자재나, 충격에 강하고 탄력성과 유연성이 우수한 보도블럭 및 내구성, 내열성, 내한성, 내마모성이 우수한 아스팔트등의 토목재등으로 제공되게한 것이어서 폐수지의 재활용으로서 국가 전체적인 자원절약의 효과와 동시에 저렴한 가격의 제품을 제공할수 있는 효과가 있는 것이다.As described above, the present invention provides a method of manufacturing a construction material using waste tires, and not only causes the waste tires to be processed without buried or burned by tens of thousands of tons annually, but also eliminates the causes of secondary pollution. Rather, it is provided as a building material with excellent waterproofing, soundproofing, windproof, heat dissipation, moisture proof, and corrosion protection, and a civil engineering material such as asphalt, which is strong in impact, elasticity and flexibility, and asphalt with excellent durability, heat resistance, cold resistance, and abrasion resistance. As a result, the recycling of waste resins has the effect of saving resources at the same time as the nation as a whole, and at the same time, providing affordable products.
