Description

Manufacturing method of one-component elastic coating waterproofing agent mainly containing waste tire

본 발명은 미세한 입자로 분쇄된 폐타이어를 주성분으로 한 일액형 탄성 도막방수제의 제조방법에 관한 것이다.The present invention relates to a method for producing a one-part elastic coating waterproofing agent mainly containing waste tires pulverized into fine particles.

일반적으로 각종 콘크리트 건축물의 지붕이나 옥상 등에는 반드시 방수시공을 하고 있으며, 종래의 방수제는 콘크리트의 방수성을 향상시키기 위한 혼화제가 일반적이며, 주성분으로 구분하면 무기질계와 유기질계로 구분된다.In general, waterproof construction is necessarily performed on roofs or rooftops of various concrete buildings, and conventional waterproofing agents are generally admixtures for improving the waterproofing properties of concrete, and are classified into inorganic and organic based on main components.

상기 유기질계 도막방수제로서는 파라핀계, 아스팔트계, 수지계 등을 들 수 있으나 도막의 접착성, 내구성, 내마모성, 외관 등의 열악으로 인한 단점으로 환영받지 못하고 있다.Paraffin-based, asphalt-based, resin-based, and the like may be used as the organic-based coating waterproofing agent. However, the organic coating coating waterproofing agent has not been welcomed due to the poor adhesiveness, durability, wear resistance, and appearance of the coating film.

본 발명은 상기와 같은 종래 유기질계 도막방수제의 문제점을 감안하여 창출한 것으로, 산업폐기물로서 재료의 수급이 용이한 폐타이어를 미세하게 분쇄한 폐타이어입자를 주성분으로 하고, 여기에 저점도 스틸렌 부타디엔 폴리머(Stylene Butadine Polymer)과 석유수지(petroleum Resin)를 혼합하여 특수 고무 탄성체로서 물기는 차단하고 공기는 방출시킬 수 있도록 하므로서 도막방수층에 에어포켓(부풀음) 현상이 없는 탄성 도막방수제를 제공함에 목적을 두고 창출한 것이며, 본 발명의 다른 목적은 신장율과 인장력이 우수하여 콘크리트 크랙발생시 파단되지 않고 그 크랙부분을 보호함과 동시 방수기능을 발휘할 수 있는 탄성 도막방수제를 제공하는데 있으며, 본 발명의 또다른 목적은 내약품성, 내한성 및 내구성이 우수한 탄성 도막방수제를 제공하는데 특징이 있는 것이다.The present invention was created in view of the problems of the conventional organic coating waterproofing agent as described above, and is mainly composed of waste tire particles obtained by finely crushing waste tires, which are easily supplied with materials as industrial waste, and containing low viscosity styrene butadiene. It is a special rubber elastomer that mixes polymer (Stylene Butadine Polymer) and petroleum resin to block moisture and release air, thereby providing an elastic film waterproofing agent without air pockets (blowing) in the film waterproofing layer. Another object of the present invention is to provide an elastic coating waterproofing agent that can exert a waterproofing function and at the same time to protect the cracked portion without breaking during the occurrence of concrete cracks excellent in elongation and tensile strength, another object of the present invention The objective is to provide an elastic coating waterproofing agent with excellent chemical resistance, cold resistance and durability. It will have gong.

본 발명은 상기와 같은 목적을 달성하기 위한 수단으로서,The present invention as a means for achieving the above object,

중량비를 기준하여 폐타이어입자(2mm 이하인 것) 40∼75%, 스틸렌 부타디엔 폴리머 15∼40%, 석유수지 10∼20%를 혼합한 다음 상기 혼합물의 중량비에 대하여 140∼75%에 해당하는 톨루엔 및 키실렌 혼합용제로 상기 혼합물을 교반하는 것을 특징으로 하는 것이며,40 to 75% of the waste tire particles (less than 2 mm), 15 to 40% of styrene butadiene polymer, and 10 to 20% of petroleum resin are mixed based on the weight ratio of toluene and 140 to 75% by weight of the mixture. It is characterized by stirring the mixture with a xylene mixed solvent,

또한 상기 혼합물을 톨루엔 및 키실렌 혼합용제로 교반할 때 극소량의 소포제인 실리콘오일(0.11∼0.15%중량), 분산제인 아연 디에틸 디티오 카보네이트(0.04∼0.06%중량), 노화방지제인 2,2,4-트리메틸 1,2-디 하이드로 키놀린(0.11∼0.14%중량)을 가한 후 착색제인 안료(0.44∼0.50%중량)를 첨가하는 것을 특징으로 하는 것이다.In addition, when stirring the mixture with a mixed solvent of toluene and xylene, a very small amount of antifoaming silicone oil (0.11 to 0.15% by weight), dispersant zinc diethyl dithio carbonate (0.04 to 0.06% by weight), anti-aging agent 2,2 And 4-trimethyl 1,2-dihydrokinoline (0.11 to 0.14% by weight) is added, followed by addition of a pigment (0.44 to 0.50% by weight) as a colorant.

본 발명의 실시예를 설명하면 다음과 같다.An embodiment of the present invention will be described as follows.

주요성분인 폐타이어분말은 산업폐기물인 폐타이어에서 와이어강선은 제거하고 보강섬유는 그대로 남겨둔 채 분쇄기를 이용하여 입자크기가 2mm 이하가 되게 분쇄하는 것인데, 이와 같이 분쇄되는 폐타이어분말은 미세하면 미세할수록 좋다.The waste tire powder, which is the main component, is pulverized to a particle size of 2 mm or less using a grinder while removing the wire steel wire from the waste tire, which is an industrial waste, and leaving the reinforcing fibers as it is. The better it is.

상기 폐타이어분말은 분쇄기로 분쇄되는 과정에서 미세한 기공이 형성되게 되며, 또한 분쇄입자에 남아 있는 보강섬유에 의해서도 미세한 기공이 형성되어 있게 되는데, 상기와 같이 폐타이어분말에 미세한 기공이 형성되게 한 구성은 도막방수시공을 하였을 때 물이 스며드는 것은 방지하고 공기압 또는 수증기압은 방출시켜 도막방수층이 부풀어오르는 이른바 에어포켓현상을 방지하는 특징을 나타낸다.The waste tire powder is fine pores are formed in the process of grinding with a grinder, fine pores are also formed by the reinforcing fibers remaining in the pulverized particles, the fine pores are formed in the waste tire powder as described above Silver prevents water from seeping when the coating is waterproofed and releases air pressure or water vapor to prevent the so-called air pocket phenomenon in which the coating waterproof layer swells.

상기와 같이 입자크기가 2mm 이하로 미세하게 분쇄된 폐타이어분말을 주성분으로하여 탄성 도막방수제를 제조하는 방법은 중량비 기준으로 폐타이어분말 40∼75%와, 스틸렌 부타디엔 폴리머 15∼40% 및 석유수지 10∼20%를 혼합하여 혼합물을 얻은 다음 상기 혼합물의 중량비에 대하여 140∼75%에 해당하는 톨루엔 및 키실렌 혼합용제(톨루엔과 키실렌이 1: 1 비율로 혼합된 것)를 상기 혼합물에 붓고 서서히 교반하게 되면 스틸렌 부타디엔 폴리머 성분과 석유수지 성분은 완전히 액상으로 용해되며, 폐타이어분말은 표면만 일부 용해될 뿐 분말입자상태로 남아있게 된다.The method for producing an elastic coating film waterproofing agent based on the waste tire powder finely pulverized to 2mm or less as described above is based on the weight ratio of 40 to 75%, styrene butadiene polymer 15 to 40% and petroleum resin 10 to 20% of the mixture is mixed to obtain a mixture. Toluene and xylene mixed solvent (toluene and xylene in a ratio of 1 to 1) corresponding to the weight ratio of the mixture is poured into the mixture. When slowly stirred, the styrene butadiene polymer component and the petroleum resin component are completely dissolved in the liquid phase, and the waste tire powder is dissolved in only part of the surface and remains as powder particles.

상기와 같이 톨루엔 및 키실렌 혼합용제에 의하여 액상으로 용해된 스틸렌 부타디엔 폴리머와 석유수지는 상기 혼합용제가 대기에 노출되어 휘발될 때 폐타이어분말들을 접착시켜주는 접착제의 작용을 함과 동시 콘크리트면에 강력하게 접착되는 접착제의 작용을 하게 되는 것이다.As described above, the styrene butadiene polymer and petroleum resin dissolved in the liquid phase by the toluene and xylene mixed solvent act as an adhesive to bond the waste tire powders when the mixed solvent is exposed to the atmosphere and volatilized. It will act as a strong adhesive.

그리고 상기 폐타이어분말, 스틸렌 부타디엔 폴리머 및 석유수지를 톨루엔 및 키실렌 혼합용제로 교반하는 과정에서 극소량의 소포제인 실리콘오일(0.11∼0.15%중량), 분산제인 아연 디에틸 디티오 카보네이트(0.04∼0.06%중량), 노화방지제인 2,2,4-트리메틸 1,2-디 하이드로 키놀린(0.11∼0.14)%중량)을 가한 후 착색제인 안료(0.44∼0.50%중량)를 첨가하는 것인데, 상기한 실리콘오일은 교반물에 기포가 생성되는 것을 억제하는 작용을 하며, 아연 디에틸 디티오 카보네이트는 교반물이 골고루 혼합,교반되게 하는 작용을 나타내며, 2,2,4-트리메틸 1,2-디 하이드로 키놀린은 도막시공후 도막방수층이 노화현상을 방지하는 작용이 있으며, 안료는 도막방수제를 유색으로 착색시키는 작용을 하는 것이다.In the process of stirring the waste tire powder, the styrene butadiene polymer and the petroleum resin with a mixed solvent of toluene and xylene, a very small amount of antifoaming agent silicone oil (0.11 to 0.15% by weight) and zinc diethyl dithio carbonate (0.04 to 0.06) %), 2,2,4-trimethyl 1,2-dihydrokinoline (0.11 to 0.14)% by weight) is added, followed by the addition of pigment (0.44 to 0.50% by weight) as a coloring agent. Silicone oil has a function of suppressing the formation of bubbles in the stirring material, and zinc diethyl dithio carbonate has a function of mixing and stirring the stirring evenly, and 2,2,4-trimethyl 1,2-dihydro Kinolin has a function of preventing the aging phenomenon of the coating layer after coating the coating, the pigment serves to color the coating waterproofing agent.

이와 같은 구성원리로 제조된 본 발명의 탄성 도막방수제는 액상으로 교반된 상태에서 시공되는 일액형 도막방수제로서 건축물의 지붕이나 옥상 등에 일정 두께로 도포, 시공하였을 당시에는 상기한 혼합용제가 증발되지 않은 상태이므로 액상의 성격을 띠고 있게 되어 콘크리트 시공면에 있는 공기는 응고되지 않은 도막방수층을 통과하여 대기중으로 방출되는 것이며, 상기한 혼합용제가 점차적으로 증발함에 따라 스틸렌 부타디엔 폴리머 성분과 석유수지 성분은 응고되면서 콘크리트 시공면에 강력한 접착력으로 도막방수층을 접착시킴과 동시 폐타이어분말들 상호간을 접착시켜 시이트상태로 일체화된 도막방수층을 형성하게 되는데, 상기한 폐타이어분말은 분쇄기에서 분쇄될 때 생성된 미세한 기공과 잔존하는 보강섬유에 의하여 공기압이나 수증기압은 통과시킬 수 있지만 물기는 차단하는 특징을 지니고 있게 되므로 도막방수층이 시공된 콘크리트의 노화현상이나 온도차이 등에 의하여 생성되는 공기압 또는 수증기압은 폐타이어분말에 형성된 미세한 기공과 보강섬유 사이의 기공을 통해 대기중으로 방출되므로 도막방수층이 부풀어오르는 에어포켓현상이 나타나지 않게 되며, 이에 따라서 도막방수층은 콘크리트 시공면에 접착된 상태를 장구히 보존하는 특징이 있는 것이다.The elastic coating waterproofing agent of the present invention manufactured by such a member is a one-component coating waterproofing agent which is constructed in a stirred state in a liquid state, and the mixed solvent does not evaporate when the coating or coating is applied to a roof or rooftop of a building to a certain thickness. As it is in a state of liquidity, the air in the concrete construction surface is discharged into the atmosphere through the uncoagulated waterproofing layer, and as the mixed solvent gradually evaporates, the styrene butadiene polymer component and the petroleum resin component are solidified. While adhering the waterproofing layer to the concrete construction surface with strong adhesive force and simultaneously adhering the waste tire powders to each other to form an integrated coating waterproofing layer in the sheet state, the waste tire powder is fine pores generated when pulverized in the grinder. And the remaining reinforcing fiber Water vapor pressure can pass, but water is blocked, so the air pressure or water vapor pressure generated by aging phenomenon or temperature difference of concrete on which the waterproofing layer is applied is generated through the pores between the fine pores formed in the waste tire powder and the reinforcing fiber. Since it is released into the atmosphere, the air pocket phenomenon that the film waterproof layer swells does not appear, and accordingly, the film waterproof layer has a characteristic of preserving the state adhered to the concrete construction surface for a long time.
