Description
본 발명은 아스팔트 크랙 충진재에 관한 것으로서, 보다 상세하게는 아스팔트에 발생된 크랙에 효과적인 충진이 이루어지도록 충분한 유동성을 가지면서 아스팔트 입자와의 결합이 증가되도록 된 크랙 충진재의 조성물에 관한 것이다. The present invention relates to asphalt crack fillers, and more particularly, to a composition of crack fillers having sufficient fluidity to increase effective filling of cracks generated in asphalt while increasing binding to asphalt particles.
일반적으로 아스팔트에는 외부환경에 의해 고온 및 저온의 격차가 심한 온도변화가 발생되었고, 이러한 아스팔트에 지속적인 하중과 순간적인 충격에 의해 소성변형, 탈리, 크랙 등 여러 가지 파손현상이 초래되었다.In general, the asphalt has a large temperature change due to the high temperature and low temperature due to the external environment, and various damages such as plastic deformation, detachment, and cracking are caused by continuous load and momentary impact on the asphalt.
특히, 상기 크랙은 아스팔트 입자들 간의 결합력이 극복되는 외부환경 및 외력에 의해 틈(gap)이 형성된 것으로, 이 크랙으로 공기 및 수분이 침투하게 되면 더 빠른 크랙의 진행에 따른 파손이 심각해지게 된다. 이에, 상기 크랙을 보수하기 위한 실런트(Sealant) 즉, 크랙 충진재가 제조되어 시중에 판매되고 있다. In particular, the crack is a gap formed by the external environment and external force that overcomes the bonding force between the asphalt particles, the air and moisture infiltrate into the crack is seriously damaged by the progress of the faster crack. Accordingly, sealants, that is, crack fillers, for repairing the cracks are manufactured and sold on the market.
이러한 크랙 충진재는 상기 크랙에 충진되도록 유입되어 소정의 시간이 경과되면 완전 경화됨으로써 크랙을 보수하는 것으로서, 고무첨가제와 SBS 등이 포함된 고분자 화합물과, 아스팔트가 소정의 온도에서 일정한 비율로 배합되어 이루어졌고, 또한 상기 크랙 충진재에는 크랙으로의 충진이 자연스럽게 이루어지도록 기본적인 경화(硬貨)성질에 유동성이 부여되도록 가소제(可塑劑)가 첨가되었다. These crack fillers are introduced to fill the cracks and are completely cured after a predetermined time has elapsed. The crack filler is made of a polymer compound including a rubber additive, SBS, and asphalt at a predetermined temperature at a predetermined ratio. In addition, a plasticizer was added to the crack filler so that fluidity was imparted to the basic hardening property so that filling into the crack was naturally achieved.
그러나, 상기 충진재는 크랙으로 침투되기 위한 유동성과 침투된 후 아스팔트 입자와의 점도가 일정 범위 내에 한정되어 있어 크랙의 균열정도와는 무관하게 시공됨으로 인해 때로는 현장의 상황이 고려되지 않아 충진재의 낭비 및 시공의 효율성에 문제점이 제기되었다.However, since the filler is fluidity to penetrate into the cracks and the viscosity of the asphalt particles after being penetrated is limited within a certain range and is constructed irrespective of the cracking degree of the cracks, sometimes the situation of the site is not taken into consideration because of the waste of the filler and Problems arise in the efficiency of construction.

상기 충진재에는 유동성 가변을 위해 중량부 0.1 ∼ 5인 증점제가 더 포함된다.The filler further comprises a thickener of 0.1 to 5 parts by weight for variable fluidity.
상기 고분자 화합물은 SBR 라텍스, SBS, EVA, PE, LDPE 중 1종 이상이 배합되어 이루어진다.The polymer compound is composed of one or more of SBR latex, SBS, EVA, PE, LDPE.
이하, 본 발명에 따른 크랙 충진재의 조성물을 상세히 설명한다.Hereinafter, the composition of the crack filler according to the present invention will be described in detail.
본 발명에 의한 크랙 충진재는, 유화아스팔트 중량부 100을 기준으로 SBS 라텍스, SBS, EVA, PE, LDPE 등이 포함된 중량부 10∼20인 고분자 화합물과, 크랙에 충진되어 아스팔트와의 접착력을 향상시키기 위한 중량부 5∼10인 셀룰로오스 섬유(Cellulose Fiber)이 포함된 조성물이 배합되어 이루어진다.Crack filler according to the present invention, based on 100 parts by weight of emulsified asphalt, 100 parts by weight of the polymer compound containing SBS latex, SBS, EVA, PE, LDPE and the like, and the cracks are filled with cracks to improve the adhesion to asphalt Composition comprising 5 to 10 parts by weight of cellulose fibers (Cellulose Fiber) to be made.
또한, 상기 크랙 충진재에는 시공 현장의 상태와 작업성이 고려되어 크랙 충진재의 수명이 향상되면서 압축 및 인장강도 등의 여러 강도에 대한 응력이 최대화되도록 중량부 0.1 ∼ 10인 시멘트가 더 포함될 수 있다.In addition, the crack filler may further include cement having a weight part of 0.1 to 10 so as to maximize the stress for various strengths such as compression and tensile strength while improving the life of the crack filler in consideration of the construction site condition and workability.
여기서, 상기 유화아스팔트는 크랙의 정도에 따라 크랙 충진재의 유동성을 크게 향상시키기 위해 고농도 유화아스팔트인 것이 바람직하고, 상기 고농도 유화아스팔트는 그 조성물 중 아스팔트가 중량부 65∼75로 배합되어 생산된 것이다. Here, the emulsified asphalt is preferably a high concentration of the emulsified asphalt in order to greatly improve the fluidity of the crack filler according to the degree of the crack, the high concentration of the emulsified asphalt is produced by mixing the asphalt in the composition 65 to 75 parts by weight.
그리고, 상기 유화아스팔트가 유동성이 향상된 고농도 유화아스팔트인 것으로 하면서 크랙의 균열정도에 따라 그 유동성이 조정될 수 있도록 중량부 0.1 ∼ 5인 증점제(增粘劑)가 추가로 배합될 수 있다. 이 증점제의 종류로는 C(탄소)1∼C10의 성분을 갖는 알킬 셀룰로오스(Alkyl Cellulose)가 이용됨이 바람직하고, 특히 메틸(Methyl) 셀룰로오스가 이용됨이 더 바람직하다.Further, while the emulsified asphalt is to be a high-concentrated emulsified asphalt having improved fluidity, a thickener having a weight part of 0.1 to 5 may be further blended to adjust the fluidity according to the cracking degree of the crack. As the kind of the thickener, alkyl cellulose (Alkyl Cellulose) having a component of C (carbon) 1 to C10 is preferably used, and more preferably methyl cellulose is used.
상기 크랙의 균열 정도 즉, 균열이 넓고 광범위하게 발생된 경우에는 균열에 충진되는 크랙 충진재의 유동성이 다소 낮아지더라도 완전 충진이 가능하므로 경화(硬化)가 빠르게 진행되도록 증점제가 첨가되고, 또는 균열의 정도가 좁고 협소하게 발생된 경우에는 크랙 충진재의 높은 유동성이 유지되어 완전 충진을 유도할 수 있게 증점제가 배제된다.In the case where the cracks are cracked, that is, the cracks are wide and wide, they may be completely filled even if the fluidity of the crack fillers filled in the cracks is slightly lowered, so that a thickening agent is added so that the curing proceeds quickly. In narrow and narrow cases, thickeners are excluded to maintain the high fluidity of the crack fillers and induce full filling.
또한, 상기 고분자 화합물은 SBR(Styrene Butadiene Rubber) 라텍스, SBS(Styrene Butadiene Styrene), EVA(Ethylene Vinyle Acetate), PE(Poly Ethylene), LDPE(Low Density Poly Ethylene) 중 1종 이상이 배합되어 이루어진 것이다. 이 배합은 통상적으로 당업자에게 알려진 배합비율이 적용된다.In addition, the polymer compound is made of one or more of SBR (Styrene Butadiene Rubber) latex, SBS (Styrene Butadiene Styrene), EVA (Ethylene Vinyle Acetate), PE (Poly Ethylene), LDPE (Low Density Poly Ethylene) . This formulation is usually applied with a formulation ratio known to those skilled in the art.
상기와 같이 조성물의 배합이 이루어진 크랙 충진재는 셀룰로오스 섬유 및 고농도 유화아스팔트의 배합에 의해 접착력과 유동성이 향상되어 크랙으로 원활하게 침투되어 고접착력에 의한 보수가 이루어지고, 시공 현장의 상황에 맞게 시멘트가 추가 배합되어 충격 및 압축 등 다양한 강도에 대해 최대의 응력이 형성되며, 기본적으로 연화성질을 가지고 있으면서 크랙의 균열정도 및 현장의 상황에 따라 증점제가 배제 또는 추가로 배합되어 현장에 가장 적합한 보수가 이루어지게 된다. As the above-mentioned composition, the crack filler is blended with cellulose fibers and high concentration of emulsified asphalt to improve adhesion and fluidity, so that the crack penetrates into the cracks smoothly and repairs by high adhesion. It is additionally blended to create the maximum stress for various strengths such as impact and compression.In addition, it has softening properties, and the thickener is excluded or additionally formulated according to the cracking degree of the crack and the situation of the site, so that the most suitable repair is performed on the site. You lose.
상기와 같이 구성된 본 발명에 따르면, 종래의 크랙 충진재와는 달리 기본적인 연화성질에 소망 요건에 따라 증점제의 경화성질이 부여되도록 이루어지고, 시공 현장의 환경에 따라 시멘트가 첨가되어 압축 및 인장강도 등의 여러 강도에 대한 응력이 최대로 향상되며, 셀룰로오스 섬유와 고농도 유화아스팔트의 배합으로 크랙 충진재의 접착력 및 침투력이 증가되고, 증점제의 첨가로 충진재의 유동성이 인위적으로 가변될 수 있어 크랙의 균열 정도에 따라 그 배합비율이 조정됨으로써 시공 현장의 환경 및 크랙의 성질에 따라 가장 적합한 크랙 충진재가 생산될 수 있는 효과가 있다.According to the present invention configured as described above, unlike conventional crack fillers, the softening property of the thickener is given to basic softening properties according to desired requirements, and cement is added according to the environment of the construction site, such as compression and tensile strength. The stress on various strengths is improved to the maximum, and the adhesion and penetration of crack fillers are increased by the combination of cellulose fiber and high concentration of emulsified asphalt, and the fluidity of the fillers can be artificially changed by the addition of thickeners. By adjusting the compounding ratio, there is an effect that the most suitable crack filler can be produced according to the environment of the construction site and the nature of the crack.
