Description
본 발명은 재생 아스팔트 첨가제 제조방법에 관한 것으로, 보다 상세하게는 스틸렌부타디엔라텍스, 프로세스 오일 및 폴리프로필렌을 혼합하여 제1혼합물을 제조하고, 상기 제1혼합물에 EVA, LDP 및 돈지를 혼합하여 제2혼합물을 제조하고 상기 제2혼합물에 카본블랙과 난연제를 혼합하여 교반하여 제3혼합물을 제조하고 상기 혼합물을 식힌 후 성분 분리를 막기 위해 탈수기로 분산시켜 제조하는 재생 아스팔트 첨가제 제조방법에 관한 것이다. The present invention relates to a process for producing recycled asphalt additives, and more particularly to a process for producing a recycled asphalt additive, which comprises mixing a styrene butadiene latex, process oil and polypropylene to prepare a first mixture, mixing the first mixture with EVA, LDP, And mixing the carbon black and the flame retardant to the second mixture to prepare a third mixture, and cooling the mixture to disperse the mixture with a dehydrator to prevent component separation.
도로의 포장은 90% 이상이 아스팔트 콘크리트 포장이나 아스팔트 콘크리트 포장도로는 급속한 교통량의 증가로 인하여 소성변형과 균열 등으로 공용수명이 다하지 못하고 파손으로 인해 유지보수비가 증가되고 있다. 파손되는 폐아스팔트 콘크리트의 적절한 방법을 통한 재활용은 경제적으로는 물론 환경적으로도 해결해야할 문제이다. Asphalt concrete pavement and asphalt concrete pavement have more than 90% of the pavement on the road. Due to the rapid increase of traffic volume, the pavement has not been fully used due to plastic deformation and cracking. Recycling of damaged waste asphalt concrete through proper methods is an economic and environmental problem.
폐아스팔트 콘크리트인 아스콘의 재생 방법으로 상온 재생과 가열 재생이 있다. 상온재생은 폐아스콘 순환골재에 신규아스팔트와 골재를 첨가하여 상온포장용 혼합물을 생산하기 위한 공정이다. 상온재생이란 열을 가하지 않고 폐아스콘을 재생하는 것을 일컫는다. 가열 재생아스콘이 폐아스콘 순환골재를 신규골재와는 별도의 장치에서 가열한 후 믹서기에서 이미 가열된 신규골재 및 아스팔트와 함께 혼합하여 생산되는 것에 비해 상온 재생아스콘은 폐아스콘 재생골재와 신규골재 및 유화 아스팔트를 가열하지 않고 상온에서 혼합하여 생산하고 시공하는 도로포장용 아스팔트 제품이다. As a method of regenerating asphalt which is waste asphalt concrete, there is room temperature regeneration and heating regeneration. Room temperature regeneration is a process for producing a mixture for room temperature packing by adding new asphalt and aggregate to waste asbestos recycled aggregate. Room temperature regeneration refers to regeneration of waste asbestos without applying heat. The recycled asbestos recycled asbestos is heated by a device separate from the new aggregate and mixed with the already heated new aggregate and asphalt in the blender, whereas the recycled ascon at room temperature is produced from recycled asbestos aggregate, new aggregate and emulsion It is an asphalt product for road paving which is produced by mixing at room temperature without heating the asphalt.
폐아스콘의 가열재생 공법은 폐아스콘의 고온 가열로 인한 이산화탄소 등 온실가스의 배출과 악취, 매연, 분진 등에 의한 대기환경오염이 심각하다. 폐아스콘 상온재생 공법은 상온 상태의 폐자재를 원래의 골재 입도 상태로 파쇄 선별한 후 상온의 신규골재와 유화아스팔트를 상온에서 혼합하는 방식이며 가열시 필요한 석유에너지를 절감할 수 있고 친환경적인 아스콘 재생 방식이다. In the heating and reclamation method of waste asbestos, the atmospheric pollution by the emission of greenhouse gas such as carbon dioxide due to the high temperature heating of the waste asbestos, and the bad smell, soot, dust and the like is serious. The waste asbestos recycling method is a method in which waste materials at room temperature are crushed into original aggregate particle size and then mixed with new aggregate at room temperature and emulsified asphalt at room temperature. This method can reduce oil energy required for heating, Method.
대한민국공개특허 제10-1136479호는 상온 재생아스팔트 혼합물에 관한 것으로 폐아스콘의 재활용을 통해 폐기물 처리 비용과 골재 및 아스팔트 자원을 절약하는 것과 동시에 환경오염을 방지하기 위한 폐아스팔트 콘크리트 재생 첨가제를 제공하는 것이다. 그러나 폐아스팔트 콘크리트에 재생 첨가제를 사용함에 따른 공해 문제를 방지할 수 있을 뿐 재생된 아스콘의 결합력이 약하여 입자가 탈리되거나 부식성 등의 문제점이 있다. Korean Patent Laid-Open Publication No. 10-1136479 discloses a recycle asphalt concrete mixture for saving waste treatment cost, aggregate and asphalt resources and preventing environmental pollution through recycling waste asphalt . However, it is possible to prevent the problem of pollution due to the use of the recycling additive in the waste asphalt concrete, but the recycling of the recycled asphalt has a weak binding force, resulting in particle detachment or corrosion.
본 발명은 종래의 문제점을 해결하기 위하여 고분자 개질제, 카본블랙, 양이온 계면활성제, 황산염계 자극제 및 물을 혼합하여 재생아스팔트의 결합력을 강하게 유지하며 마모성, 인장강도 및 탄성율이 향상된 재생 아스팔트용 첨가제를 제공하는 것이다. The present invention provides an additive for regenerated asphalt which is improved in abrasion resistance, tensile strength and elastic modulus by strongly retaining the binding force of regenerated asphalt by mixing polymer modifier, carbon black, cationic surfactant, sulfate stimulant and water to solve the problems of the prior art .
