Description

아스팔트 및 콘크리트용 고분자 바인더 조성물{binder composition for asphalt}Polymer binder composition for asphalt and concrete

본 발명은 아스팔트 및 콘크리트의 물성 개질을 위한 고분자 바인더 조성물에 관한 것으로서, 좀더 상세히는 아스팔트 및 콘크리트 5-65 중량％, 물 35-95 중량％에 아스팔트 및 콘크리트 중량 기준으로 양이온 또는 음이온 계면활성제 0.1-3 중량부, 비이온 계면활성제 0.1-3 중량부 및 양쪽성 계면활성제(amphoteric surface active agents) 0.1-2 중량부와 물유리 5∼15 중량부 및 라텍스 5∼20 중량부를 포함하는 아스팔트 및 콘크리트용 고분자 바인더 조성물에 관한 것이다.The present invention relates to a polymer binder composition for modifying the properties of asphalt and concrete, more specifically 5-65% by weight of asphalt and concrete, 35-95% by weight of water 0.1-cation or anionic surfactant based on the weight of asphalt and concrete 3 parts by weight, 0.1-3 parts by weight of nonionic surfactant and 0.1-2 parts by weight of amphoteric surface active agents, 5-15 parts by weight of water glass, and 5-20 parts by weight of latex polymer for asphalt and concrete It relates to a binder composition.

일반적으로 포장에는 가열 아스팔트 포장과 상온 아스팔트 포장으로 나눌 수 있다. 가열 아스팔트포장은 현재 널리 사용되고 있는 포장방법이기는 하지만, 아스팔트와 골재를 혼합할 때 고온(150-180℃)에서 행하기 때문에 탄산가스나 유독 가스의 배출로 인한 공해문제가 심각하고, 가열비용과 가열설비에 따른 비용도 무시 못한다. 그리고 가열 아스콘이 냉각되기 전에 포장현장까지 운반하여 다짐을 완료해야 하는 온도관리에 대한 제약 조건도 있다.In general, the pavement can be divided into heated asphalt pavement and room temperature asphalt pavement. Heated asphalt pavement is a widely used pavement method, but since it is carried out at high temperature (150-180 ° C) when mixing asphalt and aggregate, the pollution problem caused by the emission of carbon dioxide or toxic gas is serious, heating cost and heating The cost of equipment is also not negligible. There are also constraints on temperature control that require the transport of asbestos to be completed before the heated ascon is cooled.

이에 반하여 친수성 상온 아스팔트포장의 장점은 첫째, 화재위험이 적고, 둘 째, 폭발성 용제가 거의 존재하지 않고, 셋째, 골재표면이 다소 젖어 있어도 접착하는 데에 아무런 문제가 없고, 넷째, 환경 친화적이고, 비용도 저렴한 장점이 있다.On the contrary, the advantages of hydrophilic room-temperature asphalt pavement are: 1) low risk of fire, 2) almost no explosive solvent, 3) no problem in bonding even if the aggregate surface is slightly wet, 4) environmentally friendly, The cost is also low.

그러나 단점으로는 가열 아스팔트 포장에 비하여 물이 증발하는 속도가 느려 경화속도가 떨어지고, 물리적 강도 또한 상대적으로 취약한 점 등을 들 수 있다. 또한 수용성 계면활성제가 포함되어 있으므로 물에 노출될 때 물과 재결합하여 포장기능에 손상을 가져올 수도 있다. 이러한 문제점들 때문에 많은 장점에도 불구하고 친수성 상온포장은 가열포장에 비하여 현재 사용빈도수 면에서 훨씬 떨어진다.However, the disadvantage is that the rate of hardening is low due to the slow evaporation rate of water compared to the heated asphalt pavement, and the physical strength is also relatively weak. It also contains a water-soluble surfactant, which may recombine with water when exposed to water and cause damage to packaging. Due to these problems, despite the many advantages, hydrophilic room temperature packaging is far lower in current use frequency than heating packaging.

이러한 상온 아스팔트 포장에는 골재와 함께 필수적으로 첨가되는 재료로 친수성 유화 아스팔트 바인더가 있는 데, 이 유화제의 성능에 따라 포장특성이 결정된다. 본 발명은 위에서 지적한 친수성 상온포장의 여러 단점들을 해결하고자 기존의 유화제를 개량 발전시켜 그 성능이 우수한 새로운 개념의 친수성 유화 아스팔트 바인더를 제조하는 기술과 이 유화제를 사용하여 포장하는 새로운 포장방법이 포함된다.The room temperature asphalt pavement has a hydrophilic emulsified asphalt binder as an essential material to be added with the aggregate, the pavement properties are determined according to the performance of the emulsifier. The present invention includes a technique for producing a new concept hydrophilic emulsified asphalt binder with improved performance by improving the existing emulsifier to solve the various disadvantages of the hydrophilic room temperature packaging pointed out above, and a new packaging method for packaging using the emulsifier. .

아스팔트 바인더 유화제는 물에 아스팔트를 분산시켜 만드는 데, 이때 분산제로서 계면활성제가 사용된다. 계면활성제는 이온의 전하에 따라 양이온, 음이온, 비이온으로 각각 나누어지며, 따라서 아스팔트 바인더 유화제도 양이온, 음이온, 비이온으로 구분된다. 이중 특히 화강암 골재(60-80 가 음이온 성분으로 구성됨)가 주종을 이루는 국내 아스팔트 포장에는 거의 양이온 아스팔트 유화제가 주로 사용되고 있다.Asphalt binder emulsifiers are made by dispersing asphalt in water, where a surfactant is used as the dispersant. Surfactants are divided into cationic, anionic and nonionic depending on the charge of the ions, and therefore asphalt binder emulsifiers are also classified into cationic, anionic and nonionic. Among them, cationic asphalt emulsifiers are mainly used in domestic asphalt pavement, which is mainly composed of granite aggregates (60-80 are composed of anion components).

아스팔트 및 콘크리트 포장에 사용되는 모든 종류의 골재에는 상대적 차이가 있기는 하지만 단일 이온으로 구성되지 않고, 양이온과 음이온 두 성분으로 구성되어 있다. 예를 들어, 국내의 포장에 흔히 사용되는 화강암에는 음이온 성분이 60-80, 양이온 성분이 20-40를 차지하며, 골재 공극 (air void) 채움재 (filler)로 널리 사용되는 석(회)분에도 음이온 성분이 30-50와 양이온이 50-70로 이루어져 있다. 따라서 아스팔트포장에 들어가는 골재와 채움재에는 양이온과 음이온 성분 둘 다 공존한다.All types of aggregates used in asphalt and concrete pavements, although there are relative differences, do not consist of single ions, but consist of two components, cation and anion. For example, granite commonly used in domestic packaging accounts for 60-80 anion components and 20-40 cationic components, and it is also used for lime (ash), which is widely used as an air void filler. It consists of 30-50 anion component and 50-70 cation. Therefore, both the cation and anion components coexist in the aggregate and the filler that enter the asphalt pavement.

특히, 최근에 개발된 심팔트(cemphalt) 포장에도 음이온 성분이 주를 이루는 화강암이나 흙 또는 모래 이외에 양이온으로 구성된 시멘트가 다량 포함되어 있어 양이온과 음이온 성분 둘 다 공존한다. 또한 자원 재활용과 환경오염 제거를 위한 폐아스팔트 콘크리트의 상온재생에도 다량의 시멘트가 첨가되는 데, 이러한 재생재료도 양이온과 음이온 그리고 비이온으로 구성되어 있다.In particular, recently developed cemphalt pavement contains a large amount of cement is composed of cations in addition to the granite, soil or sand mainly composed of anion components coexist both cation and anion components. In addition, a large amount of cement is added to room temperature regeneration of waste asphalt concrete for resource recycling and environmental pollution. The regeneration material is composed of cations, anions, and nonions.

따라서 양이온이나 음이온, 비이온계로 구분되는 단일이온 유화 아스팔트는 유화된 아스팔트표면의 전하와 골재표면의 전하가 다를 경우에는 유화상태의 파괴가 빨라져 경화가 촉진되며 아울러 접착력 개선도 성취할 수 있으나, 같을 경우에는 서로 반발하여 골재표면에서의 유화입자 파괴가 거의 이루어지지 않아 그 표면부분에서는 경화가 느리며 접착력 또한 현격히 떨어지는 문제점이 있다.Therefore, the monoionic emulsified asphalt, categorized as cationic, anionic, or nonionic, can accelerate the hardening of the emulsified state when the charge on the emulsified asphalt surface and the charge on the aggregate surface are different, thereby promoting hardening and improving adhesion. In this case, the repulsion of the emulsion particles on the surface of the aggregate is hardly achieved, so that hardening is slow at the surface portion, and there is a problem in that the adhesive strength is also significantly decreased.

이러한 이유로 양이온, 음이온, 또는 비이온 중 단일 유화제로는 골재 전체 표면의 완전접착을 기대할 수 없기 때문에 친수성 상온 아스팔트포장은, 열에 의해 골재표면 전체를 피막하는 (coating) 가열 아스팔트 포장에 비하여, 바람직한 물리 적 강도를 성취할 수 없었던 것이 사실이다.For this reason, hydrophilic room-temperature asphalt pavement is preferable to heat-based asphalt pavement where the entire surface of the aggregate is coated by heat because a single emulsifier of cation, anion, or non-ion cannot be expected to fully bond the aggregate surface. It is true that enemy strength could not be achieved.

상기의 문제점을 해결하기 위하여 본 발명의 목적은 양쪽성 계면활성제와 고분자 라텍스와 물유리를 혼합한 아스팔트 및 콘크리트 포장에서 요구되는 물리적 강도를 한층 향상시키고, 내구성 및 접착성을 향상시킨 고분자 바인더를 제공하는 것이다.In order to solve the above problems, an object of the present invention to further improve the physical strength required in the asphalt and concrete pavement mixed with the amphoteric surfactant, polymer latex and water glass, to provide a polymer binder with improved durability and adhesion will be.

상기의 목적을 달성하기 위하여 본 발명은 아스팔트 및 콘크리트 5-65 중량％, 물 35-95 중량％에 아스팔트 및 콘크리트 중량 기준으로 양이온 또는 음이온 계면활성제 0.1-3 중량부, 비이온 계면활성제 0.1-3 중량부 및 양쪽성 계면활성제(amphoteric surface active agents) 0.1-2 중량부와 물유리 5∼15 중량부 및 라텍스 5∼20 중량부를 포함하는 아스팔트 및 콘크리트용 고분자 바인더 조성물에 관한 것이다.In order to achieve the above object, the present invention provides 5-65% by weight of asphalt and concrete, 35-95% by weight of water based on the weight of asphalt and concrete 0.1-3 parts by weight of cationic or anionic surfactant, nonionic surfactant 0.1-3 The present invention relates to a polymer binder composition for asphalt and concrete, comprising 0.1-2 parts by weight and amphoteric surface active agents, 5-15 parts by weight of water glass, and 5-20 parts by weight of latex.

또한, 본 발명은 상기 아스팔트는 침입도가 80∼130인 것을 특징으로 하는 아스팔트 고분자 바인더 조성물에 관한 것이다.In addition, the present invention relates to an asphalt polymer binder composition, wherein the asphalt has a penetration of 80 to 130.

또한, 본 발명은 상기 라텍스는 SBS 또는 SBR 중 선택되는 1종 이상을 사용하는 것을 특징으로 하는 아스팔트 및 콘크리트용 고분자 바인더 조성물에 관한 것이다.In addition, the present invention relates to a polymer binder composition for asphalt and concrete, characterized in that the latex is used at least one selected from SBS or SBR.

〈각종 계면활성제〉<Various surfactants>

지금까지의 상업용 유화 아스팔트는 양이온 또는 양이온-비이온 계면활성제 로 만든 양이온 유화 아스팔트나, 음이온 또는 음이온-비이온 계면활성제로 만든 음이온 유화 아스팔트가 주종을 이루어 왔다. 그러나 본 발명에서는 처음으로 양이온, 음이온, 비이온, 양(쪽)성이온 계면활성제, 고분자 전해질 등을 각각 적절한 조성비로 조합하여 복합 유화 (아스팔트) 바인더를 제조하는 데 성공하였다. 이 복합 유화 (아스팔트) 바인더를 제조하는 데 사용될 수 있는 각 계면활성제와 고분자 전해질을 소개하면 다음과 같다.Until now, commercial emulsified asphalt has been predominantly cationic emulsified asphalt made of cationic or cation-nonionic surfactant or anionic emulsified asphalt made of anionic or anionic-nonionic surfactant. However, in the present invention, for the first time, a composite emulsion (asphalt) binder was successfully manufactured by combining cations, anions, nonions, amphoteric surfactants, and polymer electrolytes in appropriate composition ratios. Introducing each surfactant and polymer electrolyte that can be used to prepare this composite emulsified (asphalt) binder is as follows.

양이온 계면활성제는 주로 질소계의 4차 암모늄염을 말하는 데, 산성영역에서 물에 용해도가 좋고, 양이온의 성질을 나타낸다. 양이온 유화제는 골재와의 부착성이 양호하며, 유화입자의 분해진행도 빨라 교통개방이 비교적 짧은 시간 내에 이루어지므로 선호도가 높지만 음이온 계면활성제에 비하여 유화 안정성이 떨어지는 경향이 있다.Cationic surfactant mainly refers to nitrogen-based quaternary ammonium salt, solubility in water in the acidic region, and exhibits the properties of the cation. Cationic emulsifiers have good adhesion with aggregates and accelerate the decomposition of emulsified particles, so that the opening of traffic is achieved within a relatively short time. However, the cationic emulsifier tends to have lower emulsion stability than anionic surfactants.

예를 들어, 양이온 계면활성제로서 알킬 4차 암모늄염은 아래와 같다. 이외에도 Alkyl dimethyl Benzyl ammonium chloride, Methyl triethanol-ammonium-methylsulfate dialkylester, Dimethyl Alkyl Amine, 제2급 고급알콜 에톡시 슬페이트, 알긴산 에스테르염 등이 있다.For example, alkyl quaternary ammonium salts as cationic surfactants are as follows. In addition, there are Alkyl dimethyl Benzyl ammonium chloride, Methyl triethanol-ammonium-methylsulfate dialkylester, Dimethyl Alkyl Amine, Secondary higher alcohol ethoxy sulfate, Alginate ester salt.

또한, 여러 종류의 이미다졸염 (Imidazolinium Methosulfate, Tallow Imidazolinium methosulfate, Oleyl Imidazolinium Quaternary, Tallow Imidazolinium Quaternary)과 탈로우 아민 유도체(Tallow alkyl propylene diamine, Polyoxyethylene tallow propylene diamine, Quaternary ammonium salt ethoxylated tallow alkyl propylene diamine)도 양이온 계면활성제이다.In addition, various types of imidazole salts (Imidazolinium Methosulfate, Tallow Imidazolinium methosulfate, Oleyl Imidazolinium Quaternary, Tallow Imidazolinium Quaternary) and Tallow alkyl propylene diamine, Polyoxyethylene tallow propylene diamine, Quaternary ammonium salt ethoxylated tallow alkyl It is a cationic surfactant.

여기서, 언급한 화합물 이외에도 모든 종류의 양이온 계면 활성제가 본 발명의 유화제를 만드는 데 포함된다. 또한 PH 조절용으로 염산, 초산 등이 사용되고 PH가 5-6으로 비교적 높으면 골재와의 부착력이 뛰어나고, PH가 낮으면 안정성이 좋은 유제가 얻어진다.Here, in addition to the compounds mentioned, all kinds of cationic surfactants are included to make the emulsifiers of the present invention. In addition, hydrochloric acid, acetic acid, etc. are used for pH control, and when the pH is 5-6, the adhesive force with the aggregate is excellent, and when the pH is low, a good emulsion is obtained.

또한 저장 안정성의 향상을 위한 점도 조절용으로 염화칼슘이나 염화마그네슘이 유제에 비해 0.1정도 통상 첨가된다. 비이온성 계면활성제의 특징은 아스팔트 성질에 적정한 HLB의 유화제를 얻게 해 준다는 점이다. 그러나 골재에 대한 흡착력, 시공 후의 유화파괴력이 불량하기 때문에 단독으로 사용하지 않고 양이온이나 음이온과 병용하여 사용한다.In addition, calcium chloride or magnesium chloride is usually added in an amount of about 0.1 relative to the emulsion to adjust the viscosity for improving storage stability. A feature of nonionic surfactants is that they provide an emulsifier of HLB suitable for asphalt properties. However, since the adsorption power to aggregate and emulsification destruction after construction are poor, they are not used alone but in combination with cations or anions.

비이온 유화제로서는 폴리옥시에칠렌알킬에텔 유도체(Polyoxyethylenealkylether derivatives), POE-Alkylaryl Ether, POE high fatty acid Ester, 폴리옥시에칠렌노닐페닐에텔 유도체(Polyoxyethylenenonylphenylether derivatives), 폴리옥시에칠렌알킬아민 유도체(Polyoxyethylenealkylamine derivatives), 폴리옥시에칠렌알킬에스텔 유도체(Polyoxyethylenealkylester derivatives), 폴리옥시에칠렌캐스터유 유도체(Polyoxyethylene castor oilderivatives), 솔비탄 지방산 유도체 (sorbitan fatty acid ester derivative), 폴리옥시에칠렌글리콜 유도체 (Polyoxyethyleneglycol derivatives) 등이 있다. 여기서 언급한 화합물 이외에도 모든 종류의 비이온 계면활성제가 본 발명의 유제를 만드는 데 포함된다.Nonionic emulsifiers include polyoxyethylene alkylether derivatives, POE-Alkylaryl Ether, POE high fatty acid esters, polyoxyethylene nonylphenylether derivatives, polyoxyethylene alkylamine derivatives, and polyoxyethylene alkylamine derivatives Polyoxyethylene alkylester derivatives, polyoxyethylene castor oil derivatives, sorbitan fatty acid ester derivatives, polyoxyethylene glycol derivatives, and the like. In addition to the compounds mentioned herein, all kinds of nonionic surfactants are included in making the emulsions of the present invention.

음이온 계면활성제는 저가로 유화가 용이하지만 골재와의 부착성이 나쁘고 경화속도가 더뎌서 상온아스팔트포장에 음이온 계면활성제 단독으로는 많이 사용되지 않는 편이다. 음이온 계면활성제의 예로서 수지산나트륨염, 리그닌술폰산알카리금속염, Naphthalene Sulfonic acid 와 Formaldehyde Condensation, Alkyl Naphthalene 유도체, Chlorobenzene 유도체, Alkylaryl Sulfonate, 고급지방산알카리금속염, 알킬벤젠슬폰산염, 알파-올레핀슬폰산염, 폴리옥시에칠렌알킬페닐에텔류, 알킬아릴슬폰산나트륨류, Alkyl Phosphate, Sodium (POE) Alkyl Aryl Ether Sulfate, Ammonium (POE) Alkyl Aryl Ether Sulfate 류 (1-nonyl-phenoxy-2- polyoxy-ethylene-3-allyl-oxy-propaneammonium-sulfate, 1-nonyl-phenoxy-2-polyoxy-ethylene-3-ammonium-sulfate, 등), Sodium DitylSulfosuccinate 등이 있다. 여기서 언급한 화합물 이외에도 모든 종류의 음이온 계면 활성제가 본 발명의 유화제를 만드는 데 포함된다.Anionic surfactants are easily emulsified at low cost, but have poor adhesion to aggregates and are slow to cure, and therefore, anionic surfactants are not often used alone in room temperature asphalt packaging. Examples of anionic surfactants include sodium resinate, lignin sulfonic acid alkali metal salts, Naphthalene Sulfonic acid and Formaldehyde Condensation, Alkyl Naphthalene derivatives, Chlorobenzene derivatives, Alkylaryl Sulfonate, higher fatty acid alkali metal salts, alkylbenzene sulfonates, alpha-olefin sulfonates, poly Alkyl Phosphate, Alkyl Phosphate, Sodium (POE) Alkyl Aryl Ether Sulfate, Ammonium (POE) Alkyl Aryl Ether Sulfate (1-nonyl-phenoxy-2- polyoxy-ethylene-3- allyl-oxy-propaneammonium-sulfate, 1-nonyl-phenoxy-2-polyoxy-ethylene-3-ammonium-sulfate, etc.), and Sodium DitylSulfosuccinate. In addition to the compounds mentioned herein, all kinds of anionic surfactants are included to make the emulsifiers of the present invention.

양쪽성 계면활성제는 크게 4가지 종류로 분류할 수 있는 데, 이를 나열하면 다음과 같다. 첫째가 베타인형(-CH(N+(CH3)3)COO-)으로 미리스틸 베타인, N-tadecyl Oxymethyl-N,N-Dimethyl Betain, N-℃tadecyl Oxymethyl-N,N-Diethyl Betain, 등이 있다. 둘째가 글리신형 (-NH-CH2-COOH)으로 주로 살균 소독제 용도로 사용되는 데, C12H25-(NH-CH2-CH2)2-NH-CH2-COOHHCl, (C8H17- NH-CH2-CH2)2N- CH2-COOHHCl 등이 있다. 셋째가 알라닌형 (-NH-CH2-CH2-COOH)으로 C12H25-NH- CH2-CH2-COOHHCl 등이 있다. 넷째가 Sulfobetain형(-NH-SO3H)으로 C17H35-NH(HCl)-CH2-CH2-SO3Na, C17H35-NH(HCl)-CH2-C6H4-SO3Na 등이 있다. 여기서 언급한 화합물 이외에도 모든 종류의 양쪽성 이온 계면활성제가 본 발명의 유화제를 만드는데 포함된다.Amphoteric surfactants can be classified into four types, which are listed as follows.
