Description

도로포장용 아스팔트 그리드 보강재{ASPHALT GRID MATERIAL FOR ROAD PAVING}Asphalt grid reinforcement for road pavement {ASPHALT GRID MATERIAL FOR ROAD PAVING}

본 발명은 도로포장용 아스팔트 그리드 보강재에 관한 발명으로, 보다 상세하게는 종방향 섬유와 횡방향 섬유가 서로 교차하여 격자형태로 형성되는 섬유그리드를 폴리에틸렌(PE) - 폴리프로필렌(PP) 공중합체(PE-PP Copolymer)와 호모 폴리프로필렌(Homo PP)으로 이루어진 수지에 함침시키고 디사이클로펜타디엔(DCPD)이 첨가된 아스팔트 그리드 보강재에 관한 것이다. 이로 인해, 아스팔트 바인더와의 접착강도, 경도 및 내열성이 개선된다.The present invention relates to an asphalt grid reinforcing material for road pavement, and more particularly, a fiber grid formed in a grid shape by intersecting longitudinal fibers and transverse fibers with polyethylene (PE)-polypropylene (PP) copolymer (PE) -PP Copolymer) and homopolypropylene (Homo PP) impregnated with a resin and dicyclopentadiene (DCPD) is added to the asphalt grid reinforcement. Due to this, the adhesive strength with the asphalt binder, hardness, and heat resistance are improved.

일반적으로 아스팔트는 도로를 구축하는데 사용된다. 아스팔트(Asphalt)는 주로 수소 및 탄소로 구성되어 있고, 소량의 질소, 황, 산소가 결합된 화합물로 이루어진다.In general, asphalt is used to build roads. Asphalt is mainly composed of hydrogen and carbon, and a small amount of nitrogen, sulfur, and oxygen are combined with a compound.

이러한 아스팔트는 도로에 단일층으로 포설하는 경우, 아스팔트 상면에 균열이 발생되면 아스팔트 하면까지 그 충격이 그대로 전달되는 문제점이 있었다. 이로 인해 아스팔트의 일부분 손상만으로 전체를 사용할 수 없게 되어 아스팔트의 수명이 짧아지게 되고, 보수 및 재시공비용이 과다하게 소요되는 문제점이 있었다.When the asphalt is installed as a single layer on a road, when a crack occurs on the upper surface of the asphalt, the impact is transmitted to the lower surface of the asphalt as it is. As a result, only a part of the asphalt could not be used as a whole, resulting in a shortened lifespan of the asphalt, and excessive repair and re-construction costs.

이러한 문제를 극복하기 위해, 최근에는 아스팔트 층 사이에 필름을 삽입하거나, 아스팔트 자체에 유리섬유를 함침시켜 아스팔트 등의 강도를 보강할 수 있는 기술들이 개발되었다.In order to overcome this problem, recently, technologies capable of reinforcing the strength of asphalt by inserting a film between the asphalt layers or impregnating glass fibers into the asphalt have been developed.

도 1은 종래의 필름층 삽입을 통한 아스팔트의 강도를 보강하는 예를 설명한 것이다. 아스팔트 층을 기존과 같이 단일층이 아닌 2개의 층(1, 2)으로 나누어 층 사이에 필름(3)을 삽입하게 된다면, 아스팔트 상면에서 균열이 발생하더라도 아스팔트 하면에 전달되기 전 필름(3)이 충격을 흡수하여 내구성이 증대되는 효과가 있었다. 여기서 사용되는 필름(3)은 일반적으로 저밀도 폴리에틸렌(LDPE) 필름이 사용되며, 유리섬유를 함침하여 강도를 보강하였다. 또한, 저밀도 폴리에틸렌 필름을 대체하여 에틸렌초산비닐 공중합체(EVA) 수지에 유리섬유가 함침된 보강재를 사용하기도 하였다.1 illustrates an example of reinforcing the strength of asphalt through the conventional film layer insertion. If the asphalt layer is divided into two layers (1, 2) rather than a single layer as before and the film (3) is inserted between the layers, even if a crack occurs on the upper surface of the asphalt, the film (3) is not transferred to the lower surface of the asphalt. It has the effect of absorbing shock and increasing durability. As the film 3 used here, a low-density polyethylene (LDPE) film is generally used, and the strength is reinforced by impregnating glass fibers. In addition, a reinforcing material impregnated with glass fibers in an ethylene vinyl acetate copolymer (EVA) resin was used to replace the low-density polyethylene film.

그러나, 아스팔트 층(또는 아스팔트 바인더)와의 접착력이 약한 문제점이 있으며, 경도가 커 무거운 차량에 대한 충격의 흡수성이 낮은 문제점이 있었다. 따라서, 기존의 필름 혹은 보강재만으로는 충격을 흡수할 수 있는 물성 측면에서 한계가 있다.However, there is a problem in that the adhesive strength with the asphalt layer (or asphalt binder) is weak, and the hardness is high, and there is a problem in that the absorption of the impact to a heavy vehicle is low. Therefore, there is a limit in terms of physical properties that can absorb an impact only with the existing film or reinforcing material.

However, the present invention may be embodied in many different forms and is not limited to the embodiments described herein.

아스팔트 층 사이에 삽입되는 본 발명에 따른 아스팔트 그리드 보강재(1000)의 섬유그리드(100)는 도 2와 같이 종방향 섬유(110)와 횡방향 섬유(120)가 서로 교차하여 격자 형태로 형성되는 것이 바람직하다. 또한, 섬유는 유리섬유(Glass Fiber)인 것이 바람직하다.The fiber grid 100 of the asphalt grid reinforcement 1000 according to the present invention inserted between the asphalt layers is formed in the form of a grid by crossing the longitudinal fibers 110 and the transverse fibers 120 as shown in FIG. 2 . desirable. In addition, the fiber is preferably a glass fiber (Glass Fiber).

섬유그리드(100)는 후술하겠지만, 수지에 함침되어 아스팔트 그리드 보강재(1000)로 제조되고, 아스팔트 그리드 보강재(1000)가 아스팔트 층 사이에 삽입된다.Although the fiber grid 100 will be described later, it is impregnated with a resin to make the asphalt grid reinforcement 1000, and the asphalt grid reinforcement 1000 is inserted between the asphalt layers.

본 발명에 따른 섬유그리드(100)가 함침되는 수지는 폴리에틸렌(PE) - 폴리프로필렌(PP) 공중합체(PE-PP Copolymer)와 호모 폴리프로필렌(Homo PP)으로 이루어진 수지인 것이 바람직하다.The resin into which the fiber grid 100 according to the present invention is impregnated is preferably a resin composed of polyethylene (PE)-polypropylene (PP) copolymer (PE-PP copolymer) and homo polypropylene (Homo PP).

폴리에틸렌-폴리프로필렌 공중합체(PE-PP Copolymer)는 연성을 지녀 러버(Rubber)와 성질이 유사하다. 폴리에틸렌-폴리프로필렌 공중합체(PE-PP Copolymer)로 인해, 본 발명에 따른 아스팔트 그리드 보강재(1000)의 경도가 기존 필름에 비해 낮아지는 효과가 있다. 이에 관련해서는 후술할 실험예를 통해서 상세히 설명하도록 한다.Polyethylene-polypropylene copolymer (PE-PP Copolymer) has similar properties to rubber due to its ductility. Due to the polyethylene-polypropylene copolymer (PE-PP copolymer), the hardness of the asphalt grid reinforcement 1000 according to the present invention is lower than that of the conventional film. In this regard, it will be described in detail through an experimental example to be described later.

첨가제로는 디사이클로펜타디엔(디시클로펜타디엔, DCPD)이 첨가된다. 디사이클로펜타디엔(DCPD)은 사이클로펜타다이엔의 이합체로, 폴리에틸렌-폴리프로필렌 공중합체(PE-PP Copolymer) 및 호모 폴리프로필렌(Homo PP) 수지에 첨가되어 아스팔트 그리드 소재에 접착성을 부여한다.Dicyclopentadiene (dicyclopentadiene, DCPD) is added as an additive. Dicyclopentadiene (DCPD) is a dimer of cyclopentadiene and is added to polyethylene-polypropylene copolymer (PE-PP Copolymer) and homo polypropylene (Homo PP) resins to impart adhesion to asphalt grid materials.

또한, 첨가제로 카본 블랙(C/B), 산화방지제, 윤활제 및 상용화제가 폴리에틸렌-폴리프로필렌 공중합체(PE-PP Copolymer) 및 호모 폴리프로필렌(Homo PP) 수지에 첨가된다. 이때, 산화방지제는 페놀계, 윤활제는 스테아릭애씨드계, 상용화제는 무수말레인산계인 것이 바람직하다.In addition, as additives, carbon black (C/B), antioxidants, lubricants and compatibilizers are added to polyethylene-polypropylene copolymer (PE-PP Copolymer) and homo polypropylene (Homo PP) resins. In this case, the antioxidant is preferably phenolic, the lubricant is stearic acid, and the compatibilizer is maleic anhydride.

실험예 1의 실시예 1은 본 발명에 따른 보강재이다(디사이클로펜타디엔(DCPD) 10 중량부).Example 1 of Experimental Example 1 is a reinforcing material according to the present invention (10 parts by weight of dicyclopentadiene (DCPD)).

실험예 1의 실시예 2는 실시예 1과 비교할 때, 폴리에틸렌-폴리프로필렌 공중합체(PE-PP Copolymer) 100 중량부 대비 호모 폴리프로필렌(Homo PP) 중량부를 5 늘린 것이다.In Example 2 of Experimental Example 1, compared to Example 1, polyethylene-polypropylene copolymer (PE-PP Copolymer) 100 parts by weight compared to homo polypropylene (Homo PP) 5 parts by weight increased.

실험예 1의 실시예 3 내지 4는 실시예 1과 비교할 때, 폴리에틸렌-폴리프로필렌 공중합체(PE-PP Copolymer) 100 중량부 대비 디사이클로펜타디엔(DCPD)를 40 중량부, 60 중량부로 한 것이다.Examples 3 to 4 of Experimental Example 1 are 40 parts by weight and 60 parts by weight of dicyclopentadiene (DCPD) relative to 100 parts by weight of polyethylene-polypropylene copolymer (PE-PP Copolymer) compared to Example 1 .

실험예 1의 실시예 5는 실시예 4와 비교할 때, 폴리에틸렌-폴리프로필렌 공중합체(PE-PP Copolymer) 대신 고밀도 폴리에틸렌(HDPE) 수지를 100 중량부로 대체한 것이다.In Example 5 of Experimental Example 1, when compared with Example 4, 100 parts by weight of a high-density polyethylene (HDPE) resin instead of a polyethylene-polypropylene copolymer (PE-PP Copolymer) was substituted.

실시예 2에서 확인할 수 있듯이, 호모 폴리프로필렌(Homo PP) 중량부가 10인 경우, 아스팔트 그리드 보강재의 경도가 75에서 80으로 높아지는 것을 확인할 수 있다. 전술한 바와 같이 경도가 높아질수록 연성이 약해져 무거운 트럭 등을 지지할 때 아스팔트 층 전체의 내구성이 약해진다. 따라서, 실시예 1과 같이 수지의 구성이 폴리에틸렌-폴리프로필렌 공중합체(PE-PP Copolymer) 100 중량부 대비 호모 폴리프로필렌(Homo PP) 5 중량부인 것이 바람직하다.As can be seen in Example 2, when the weight part of homo polypropylene (Homo PP) is 10, it can be confirmed that the hardness of the asphalt grid reinforcement material increases from 75 to 80. As described above, the higher the hardness, the weaker the ductility, and the durability of the entire asphalt layer is weakened when supporting a heavy truck or the like. Therefore, as in Example 1, the composition of the resin is preferably 5 parts by weight of homopolypropylene (Homo PP) compared to 100 parts by weight of polyethylene-polypropylene copolymer (PE-PP Copolymer).

또한, 실시예 5에서 확인할 수 있듯이, 폴리에틸렌-폴리프로필렌 공중합체(PE-PP Copolymer) 수지 대신 고밀도 폴리에틸렌(HDPE) 수지가 사용되는 경우, 실시예 4와 비교할 때 경도가 20 높아지며, 접착강도가 15 낮아지며, 내열성이 5 낮아지는 것을 확인할 수 있다. 따라서, 폴리에틸렌-폴리프로필렌 공중합체(PE-PP Copolymer) 수지가 사용되는 것이 바람직하다.In addition, as can be seen in Example 5, when a high-density polyethylene (HDPE) resin is used instead of a polyethylene-polypropylene copolymer (PE-PP copolymer) resin, the hardness is increased by 20 compared to Example 4, and the adhesive strength is 15 It can be seen that the heat resistance is lowered by 5. Therefore, it is preferable that a polyethylene-polypropylene copolymer (PE-PP Copolymer) resin is used.

실시예 3 내지 4에서 확인할 수 있듯이, 첨가제인 디사이클로펜타디엔(DCPD)의 중량부를 늘릴수록 경도가 낮아지며, 접착강도가 높아지는 것을 확인할 수 있다.As can be seen in Examples 3 to 4, it can be confirmed that as the weight part of the additive dicyclopentadiene (DCPD) is increased, the hardness decreases and the adhesive strength increases.

이때, 바람직하게는 본 발명에서는 디사이클로펜타디엔(DCPD)의 중량부가 폴리에틸렌-폴리프로필렌 공중합체(PE-PP Copolymer) 100 중량부 대비 10 ~ 60 중량부이다. [실험예 2]는 디사이클로펜타디엔(DCPD)의 중량부에 따른 보강재의 경도, 접착강도 및 내열도를 측정한 실험이다.In this case, preferably, in the present invention, the weight part of dicyclopentadiene (DCPD) is 10 to 60 parts by weight based on 100 parts by weight of the polyethylene-polypropylene copolymer (PE-PP copolymer).

[실험예 2]의 실시예 6(중량부 10) 및 실시예 11(중량부 60)에서 확인할 수 있듯이, 실시예 6 내지 실시예 11의 구간의 전후에서 경도 및 접착강도의 개선이 다른 구간에 비해 급격하게 이루어지는 것을 확인할 수 있다(경도가 낮아지고 접착강도가 높아짐). 따라서, 본 발명에서는 디사이클로펜타디엔(DCPD)의 중량부가 폴리에틸렌-폴리프로필렌 공중합체(PE-PP Copolymer) 100 중량부 대비 10 ~ 60 중량부인 것이 바람직하다.As can be seen in Example 6 (10 parts by weight) and Example 11 (60 parts by weight) of [Experimental Example 2], the improvement of hardness and adhesive strength before and after the section of Examples 6 to 11 was different in the section It can be seen that it is formed more rapidly than that (hardness decreases and adhesive strength increases). Therefore, in the present invention, it is preferable that the weight part of dicyclopentadiene (DCPD) is 10 to 60 parts by weight relative to 100 parts by weight of the polyethylene-polypropylene copolymer (PE-PP copolymer).

이하에서는, 폴리에틸렌(PE) - 폴리프로필렌(PP) 공중합체(PE-PP Copolymer)와 호모 폴리프로필렌(Homo PP)으로 이루어진 수지가 EVA 수지로 대체된 경우와, 디사이클로펜타디엔(DCPD) 첨가제가 C5로 대체된 경우의 보강재의 경도, 접착강도 및 내열도를 측정한 실험예를 설명한다.In the following, a case where a resin composed of polyethylene (PE)-polypropylene (PP) copolymer (PE-PP Copolymer) and homo polypropylene (Homo PP) is replaced with an EVA resin, and a dicyclopentadiene (DCPD) additive An experimental example of measuring the hardness, adhesive strength and heat resistance of the reinforcing material in the case of replacing it with C5 will be described.

실험예 3의 실시예 2는 실시예 1과 비교할 때, 디사이클로펜타디엔(DCPD)을 C5로 대체한 것이다.In Example 2 of Experimental Example 3, when compared with Example 1, dicyclopentadiene (DCPD) was replaced with C5.

실험예 3의 실시예 3은 실시예 1과 비교할 때, 폴리에틸렌-폴리프로필렌 공중합체(PE-PP Copolymer)를 EVA 수지 및 폴리에틸렌-폴리프로필렌 공중합체(PE-PP Copolymer)로 대체한 것이다.In Example 3 of Experimental Example 3, when compared with Example 1, a polyethylene-polypropylene copolymer (PE-PP Copolymer) was replaced with an EVA resin and a polyethylene-polypropylene copolymer (PE-PP Copolymer).

실험예 3의 실시예 4는 실시예 1과 비교할 때, 폴리에틸렌-폴리프로필렌 공중합체(PE-PP Copolymer)를 EVA 수지로 대체한 것이다.In Example 4 of Experimental Example 3, when compared with Example 1, a polyethylene-polypropylene copolymer (PE-PP Copolymer) was replaced with an EVA resin.

실시예 2에서 확인할 수 있듯이, 디사이클로펜타디엔(DCPD)을 C5로 대체하는 경우, 경도가 5 증대되며, 접착강도가 20 낮아지며, 내열도는 변함이 없는 것을 확인할 수 있다.As can be seen in Example 2, when dicyclopentadiene (DCPD) is replaced with C5, the hardness increases by 5, the adhesive strength decreases by 20, and it can be confirmed that the heat resistance does not change.

또한, 실시예 3 및 4에서 확인할 수 있듯이, 실시예 1에 비해 경도가 낮아지고, 내열도가 낮아지며, 접착강도가 0에 수렴하는 것을 확인할 수 있다.In addition, as can be seen in Examples 3 and 4, it can be confirmed that the hardness is lowered compared to Example 1, the heat resistance is lowered, and the adhesive strength converges to zero.

따라서, [실험예 1] 내지 [실험예 3]을 종합하여 비추어 볼 때, 폴리에틸렌-폴리프로필렌 공중합체(PE-PP Copolymer) 수지 100 중량부에 대하여, 호모 폴리프로필렌(Homo PP) 수지 5 중량부, 디사이클로펜타디엔(DCPD) 10 ~ 60 중량부, 카본 블랙(C/B) 0.1 중량부, 산화방지제 0.5 중량부, 윤활제 0.5 중량부, 상용화제 0.5 중량부인 경우, 경도, 접착강도 및 내열도가 종래에 비해 개선되는 것을 확인할 수 있다.Therefore, in view of the synthesis of [Experimental Example 1] to [Experimental Example 3], 5 parts by weight of a homo polypropylene (Homo PP) resin based on 100 parts by weight of a polyethylene-polypropylene copolymer (PE-PP Copolymer) resin , 10 to 60 parts by weight of dicyclopentadiene (DCPD), 0.1 parts by weight of carbon black (C/B), 0.5 parts by weight of antioxidant, 0.5 parts by weight of lubricant, and 0.5 parts by weight of compatibilizer, hardness, adhesive strength and heat resistance It can be seen that is improved compared to the prior art.
