Abstract
Description
본 발명은 폐기되는 합성수지를 이용하여 아스팔트를 제조하는 방법에 관한 것이다.The present invention relates to a method for producing asphalt using synthetic resin discarded.
중화학공업이 발달함에 따라 거의 모든 생활용품에 석유화학제품인 합성수지제품을 사용하고 있다. 이러한 합성수지제품은 가볍고 부패되지 않으며 가공성이 뛰어난 이유로 인해 그 사용용도는 점차 증가되고 있는 반면, 이러한 합성수지제품은 그 폐기가 어려워 환경오염문제가 심각하게 대두되고 있다.As the heavy and chemical industry develops, synthetic resin products, which are petrochemical products, are used for almost all household goods. The use of these synthetic resin products is increasing gradually because of their light, non-corrosive and excellent processability, while these synthetic resin products are difficult to dispose of, causing serious environmental pollution problems.
특히 농촌용비닐, 플리스틱등 기타 잡다한 합성수지제품등을 연간 수십만톤 사용하고 있으나 사용후 마구 폐기함으로 인하여 제반 생태계까지 심각한 위협을 받게되었다.In particular, hundreds of thousands of tons of synthetic vinyl products such as vinyl, plastic, and other plastic products are used annually, but after being used, they are seriously threatened by the entire ecosystem.
한편, 이러한 폐기된 합성수지제품은 약 30% 정도가 재생되어 다른 용도로 사용할 수 있으나 70% 정도는 재생이 불가능한 저질품이므로 땅속에 매립하거나 또는 소각에 의하여 폐기처분하고 있는데, 땅속에 매립하는 경우, 상기한 합성수지제품들은 부패성이 없으므로 이에 따른 환경오염문제가 심각하게 대두되고, 소각하는 경우에는 소각시 상기 합성수지제품에서 발생되는 유독가스 및 심한 악취로 인하여 심각한 대기오염문제를 발생시키게 된다.On the other hand, about 30% of the discarded synthetic resin products are recycled and can be used for other purposes, but about 70% of the synthetic resin products are landfills disposed of in the ground or incinerated because they are poor quality that cannot be recycled. Since one synthetic resin product is not perishable, environmental pollution problems are seriously raised, and incineration causes severe air pollution problems due to toxic gas and severe odor generated from the synthetic resin product upon incineration.
본 발명은 이러한 점에 착안한 것으로 폐기된 합성수지제품의 약 70%를 차지하는 재생불가능한 합성수지제품을 이용하여 아스팔트를 제조하는 방법을 제공하는데 본 발명의 목적이 있다.It is an object of the present invention to provide a method for producing asphalt using a non-renewable synthetic resin product which accounts for about 70% of the synthetic resin products discarded in view of this point.
종래의 아스팔트는 가격이 높아 도로포장시 비용이 많이 들고 내열성이 적어 여름에는 아스팔트가 녹아 차선이 휘어지고 노면에 굴곡이 생기는 원인이 되었으며 겨울에는 강도가 약함으로 인해서 지반의 동결로 인한 파손의 우려가 많았다.As conventional asphalt has high price, it is expensive in paving roads and has low heat resistance. As a result, asphalt melts in summer, causing lanes to bend and road curvature. Many.
본 발명은 이러한 종래의 아스팔트의 단점을 개량한 새로운 아스팔트를 제조하여 원자재를 절약하여 원가를 절감하고 내열 및 내한성이 뛰어난 아스팔트를 제공할 수 있다는 장점이 있다.The present invention has the advantage that it is possible to provide a new asphalt that improves the disadvantages of the conventional asphalt to save the raw materials to reduce the cost and to provide excellent heat and cold resistance asphalt.
이하 본 발명에 따른 아스팔트의 제조방법을 상세히 설명하면 다음과 같다. 수집된 폐수지를 양질의 합성수지제품과 재생불가능한 저질의 합성수지제품으로 선별분리하여 재생가능한 양질의 합성수지제품은 다른 용도로 재생한다. 반면, 선별 분리된 재생불가능한 재질의 합성수지제품은 노에서 적당히 가열하여 용해시켜서 폐수지원료를 만든 다음, 백분율무게비에 의하여 폐수지원료 45%, 기존아스팔트 40%, 중유 10%, 촉매제 5%비율로 완전히 혼합되도록 섞은 다음에 노에서 170℃-175℃로 가열하면 기존 아스팔트보다 내열, 내한 및 경도가 우수한 아스팔트 포장재료가 얻어진다. 이렇게 하여 얻어진 본 발명의 아스팔트 포장재료에 일정량의 석분, 모래, 쇄석등을 혼합하면 기존 아스팔트보다 내열, 내한경도 특성이 우수한 본 발명의 아스팔트를 얻을 수 있다.Hereinafter, a method of manufacturing asphalt according to the present invention will be described in detail. The collected waste resin is sorted into high-quality synthetic resin product and low-quality non-renewable synthetic resin product, and recycled high-quality synthetic resin product is recycled for other purposes. On the other hand, synthetic resin products of non-renewable materials that have been separated and separated are heated in a furnace and dissolved to make wastewater support materials.Then, by weight ratio, 45% wastewater support fee, 40% conventional asphalt, 10% heavy oil, and 5% catalyst are used. Mixing to ensure complete mixing and heating to 170-175 ° C in a furnace yields an asphalt pavement with better heat resistance, cold resistance and hardness than conventional asphalt. By mixing a predetermined amount of stone powder, sand, crushed stone and the like into the asphalt pavement material of the present invention thus obtained, it is possible to obtain the asphalt of the present invention having better heat resistance and cold-hardness characteristics than conventional asphalt.
본 발명에서 가장 주의할 점은 백분율무게비로 환산하여 기존 아스팔트 40%, 중유 10%, 폐수지원료 45% 및 촉매제 5%의 성분비율을 정확히 하여서 혼합하여야 하며, 이러한 성분비가 적절하지 못하면 예를들면, 중유 및 촉매제가 필요이상으로 혼합되었을 경우는 유연성은 증가되나 경도 및 내열성이 떨어지고, 중유 및 촉매제가 상기한 성분비 이하로 되면 경도 및 내열성은 증가하나 가공 및 용해가 용이하지 않고 경도가 지나치게 증가함으로 인해 탄성 특성이 저하되어 도로포장용 재료로는 적합치 않게 된다.The most important point in the present invention should be mixed in the proportion of the weight ratio of the existing asphalt 40%, heavy oil 10%, waste water support 45% and the catalyst 5% in terms of percentage weight ratio, if such component ratio is not appropriate, for example When heavy oil and catalyst are mixed more than necessary, flexibility is increased but hardness and heat resistance are inferior. When heavy oil and catalyst are below the above component ratio, hardness and heat resistance are increased but processing and dissolution are not easy and hardness is excessively increased. As a result, the elastic properties are lowered, making it unsuitable for road paving materials.
이상과 같은 본 발명은 다음의 실시예에 의해서 기존 아스팔트 포장방법과는 조금 다르게 시공된다.The present invention as described above is constructed slightly different from the existing asphalt paving method by the following examples.

: 2차 다짐온도 : 70℃-100℃: 2nd compaction temperature: 70 ℃ -100 ℃
상기와 같은 실시예에 따라 본 발명의 아스팔트 포장재료로 도로포장시공을 한 결과 내열 및 내한특성이 우수하고 경도가 강한 아스팔트를 얻을 수 있었다.As a result of the pavement construction of the asphalt pavement material of the present invention according to the embodiment as described above was excellent in heat resistance and cold resistance characteristics and can be obtained as a strong asphalt.
본 발명의 실시예에서 아스팔트의 혼합가열온도는 반드시 170℃-175℃ 사이를 유지하여야 하며 185℃를 넘을 경우에는 아스팔트가 파란 연기를 내며 연소되므로 특성이 저하된다. 또한, 본 발명의 실시예는 기존의 아스팔트 포장온도보다 5℃-10℃ 정도 높은 온도를 유지하여 기존의 플랜트시설을 그대로 활용할 수 있으므로 별도의 플랜트 시설이 필요치 않으며, 그 포장시공 방법도 기존의 아스팔트 포장시공법에 준하여져 행해지므로 원가절감 및 폐수지이용이라는 효과를 거둘 수 있다.In the embodiment of the present invention, the mixed heating temperature of asphalt must be maintained between 170 ° C. and 175 ° C., and when it exceeds 185 ° C., the asphalt burns with blue smoke, thereby deteriorating characteristics. In addition, the embodiment of the present invention can maintain the temperature of about 5 ℃-10 ℃ higher than the existing asphalt paving temperature, so that the existing plant facilities can be utilized as it is, no separate plant facilities are required, the paving method is also conventional asphalt As it is carried out in accordance with the paving method, it can reduce costs and use waste resin.
상기한 바와같이 본 발명은 재생이 불가능하여 소각 또는 매립할 수 없는 폐수지를 도로포장용 아스팔트로 활용하므로서 소각에 따르는 대기오염과 매립으로 인한 환경오염을 방지하고 기존 폐품을 이용하여 기존의 아스팔트보다 내열, 내한특성 및 경도가 훨씬 우수한 아스팔트를 얻을 수 있으므로 일석이조의 효과를 얻을 수 있다는 장점이 있다.As described above, the present invention utilizes waste resin that cannot be incinerated or landfilled as road paving asphalt, thereby preventing environmental pollution caused by incineration and landfill, and using heat-resistant wastes. As it is possible to obtain asphalt with much better cold resistance and hardness, there is an advantage that it is possible to obtain the effect of two stones.
