본 출원자인 대한민국 특허출원 번호 94-28698에는 폐타이어 분말을 전처리 공정을 통하여 전처리 시킨 후, 여기에 자갈, 모래 등을 혼합하여 고무콘크리트를 제조하는 고무콘크리트 제조방법에 관하여 개시하고 있다.Korean Patent Application No. 94-28698, which is the present applicant, discloses a method for producing rubber concrete, in which waste tire powder is pretreated through a pretreatment process, and then mixed with gravel, sand and the like to produce rubber concrete.
그러나 고무콘크리트 제조를 위해 폐타이어 분말의 전처리공정을 거치기 때문에, 제조공정이 다소 복잡하고 또한 전처리에 필요한 열, 압력, 시간 등 이차적인 에너지원이 필요한 문제점들이 있었다.However, since the tire tire is subjected to the pretreatment process of the waste tire powder, there is a problem in that the manufacturing process is somewhat complicated and requires a secondary energy source such as heat, pressure, and time required for the pretreatment.
[발명이 이루고자 하는 기술적 과제][Technical problem to be achieved]
본 발명의 목적은 상기한 문제점을 개선하고자 전처리공정과 자갈, 모래 등을 혼합하여 혼합공정의 두단계공정을, 적절한 조건 아래서 폐타이어 분말에 재생유와 자갈, 모래 등을 혼합하여 일단계공정으로 고무콘크리트를 제조하는 개량된 제조방법을 제공하는 것이다.The object of the present invention is to improve the above problems by mixing the pretreatment process and the gravel, sand and the like in two stages of the mixing process, under the appropriate conditions by mixing the recycled oil and gravel, sand, etc. in the waste tire powder in one step process It is to provide an improved manufacturing method for producing rubber concrete.
[발명의 구성 및 작용][Configuration and Function of Invention]
본 발명에 의해 개선된 고무콘크리트 제조방법은 폐타이어를 20 내지 30 메쉬로 분쇄한 후 혼합믹서에서 황과 송진유, 톨유, 혹은 그들의 혼합물등의 재생유를 먼저 섞은 후 필요량의 자갈, 모래를 섞어 혼합물을 제조한 다음 압축성형을 통해 일단계로 고무콘크리트를 제조하는 것이다.Rubber concrete manufacturing method improved by the present invention is to crush the waste tire to 20 to 30 mesh, and then mixed the regeneration oil such as sulfur and rosin oil, tall oil, or a mixture thereof in a mixed mixer first and then the required amount of gravel, sand After preparing the mixture, the rubber concrete is prepared in one step through compression molding.
바람직하게는 상기 고무콘크리트 제조시 몰포리노벤조치아졸, 산화아연, 스테아릭산 군중의 적절한 조합에 의한 조성물의 첨가제가 더 포함될 수 있다.Preferably, the rubber concrete may further include additives of the composition by appropriate combination of morpholinobenzothiazole, zinc oxide, stearic acid crowd.
또한, 바람직하게는 자갈 및 모래를 실란 커플링제로 코팅하여 다른 첨가제들과 혼합한 후, 압축성형하여 본 발명의 고무콘크리트를 얻을 수 있다.In addition, preferably, the gravel and sand may be coated with a silane coupling agent, mixed with other additives, and then compression molded to obtain the rubber concrete of the present invention.
이때 자갈, 모래 등을 첨가하지 않고 폐타이어 분말에 재생유와 첨가제 들을 혼합하여 압축성형하여도 고무콘크리트를 제조할 수 있는데, 이렇게 제조된 고무콘크리트도 본 발명의 범주에 속한다.In this case, rubber concrete can be produced even by compression molding by mixing recycled oil and additives in the waste tire powder without adding gravel, sand, etc. The rubber concrete thus prepared is also within the scope of the present invention.
본 발명의 고무콘크리트 제조공정이 단순하고, 물성면에서도 고강도 및 초경량일 뿐만 아니라, 소음 및 진동 억제 효과 등이 우수하므로, 도로중앙분리대, 도로경계석, 침목, 해양구조물 및 건축 토목용 구조물 등의 여러 용도에 적용될 수 있을 것이다. 더구나 본 발명의 고무콘크리트는 폐타이어를 사용함으로써 폐자원 활용 측면에서도 획기적인 것이라 할 수 있다.Rubber concrete manufacturing process of the present invention is simple, high strength and ultra-lightweight in terms of physical properties, and excellent noise and vibration suppression effect, such as road central separator, road boundary stone, sleepers, offshore structures and civil engineering structures, etc. It may be applied to the purpose. Moreover, the rubber concrete of the present invention can be said to be groundbreaking in terms of waste resource utilization by using waste tires.
이하, 실시예를 들어 본 발명을 더욱 상세하게 설명하고자 한다. 그러나, 하기 예에 본 발명의 범주가 한정되는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to Examples. However, the scope of the present invention is not limited to the following examples.
[실시예]EXAMPLE
〈배합공정〉<Mixing process>
20 내지 30 메쉬 정도의 크기로 분쇄된 폐타이어 분말에 약 5-15 phr의 송진유를 혼합믹서에 첨가하여 분말표면에 이 재생유가 고르게 젖게한 후 황 1-50 phr, 몰포리노벤조치아졸 5-55 phr, 산화아연 3-100 phr, 및 스테아릭산 1-20 phr을 첨가하여 약 10분간 혼합하여 고무혼합물을 조성한다.About 5-15 phr of rosin oil is added to the mixed mixer by pulverizing waste tire powder of 20 to 30 mesh size, so that the regenerated oil is evenly wetted on the surface of the powder. Sulfur 1-50 phr, morpholinobenzothiazol 5 -55 phr, zinc oxide 3-100 phr, and 1-20 phr of stearic acid are added and mixed for about 10 minutes to form a rubber mixture.
자갈 및 모래를 실란커플링제에 약 1-3시간 동안 침지시킨 후 약 40-50도에서 24시간 정도 건조시킨다.Gravel and sand are immersed in the silane coupling agent for about 1-3 hours and then dried at about 40-50 degrees for 24 hours.
혼합 조성물 총량을 기준으로 할 때 상기 고무혼합물 10-100 중량%, 건조되고 실란커플링제로 표면처리된 자갈 30-80 중량% 및 건조되고 실란커플링제로 표면처리된 모래 40-60 중량%를 혼합하여 고무콘크리트 조성물을 제조한다.10-100% by weight of the rubber mixture, 30-80% by weight of dried and surface-treated gravel with silane coupling agent and 40-60% by weight of dry and surface-treated sand with silane coupling agent, based on the total amount of the mixture composition To prepare a rubber concrete composition.
〈성형공정〉<Molding process>
상기 조성물을 직경 10cm, 높이 20cm의 원통형 주물에 부은 후, 바이브레이터를 이용하여 약 10분 동안 다진 다음, 약 100kg/cm2의 압력과 140-170도 온도범위에서 약 20-30분 동안 압축성형하여 고무콘크리트를 제조한다.The composition was poured into a cylindrical casting having a diameter of 10 cm and a height of 20 cm, and then chopped for about 10 minutes using a vibrator, followed by compression molding for about 20-30 minutes at a pressure of about 100 kg / cm 2 and a temperature range of 140-170 degrees. Rubber concrete is prepared.
〈고무콘크리트 물성〉〈Rubber Concrete Properties〉
KSF 2405 및 KSF 2423에 규정된 방법에 따라 만능시험기를 이용하여 제조된 고무콘크리트의 압축강도를 수행한 결과, 압축강도는 고무혼합물 조성에 따라 260-920kg/cm2를 나타내었다. 이는 기존의 포틀랜드 시멘트 콘크리트의 100-600kg/cm2보다 훨씬 우수한 압축강도를 나타냈으며 기존 대한민국 특허출원 번호 94-28698에 나타난 제조공정에 따라 얻은 고무콘크리트의 압축강도인 240-960kg/cm2과 필적한 결과를 나타내어 개량된 제조공정으로도 우수한 물성의 고무콘크리트가 제조됨을 알 수 있다.The compressive strength of the rubber concrete prepared using the universal testing machine according to the methods specified in KSF 2405 and KSF 2423 was found to be 260-920 kg / cm 2 depending on the composition of the rubber mixture. This showed much better compressive strength than 100-600kg / cm 2 of the existing Portland cement concrete, comparable to 240-960kg / cm 2 , the compressive strength of rubber concrete obtained according to the manufacturing process shown in the existing Korean patent application No. 94-28698. As a result, it can be seen that rubber concrete of excellent physical properties is produced even in an improved manufacturing process.
