Abstract
Description
에폭시수지에 사용되는 폴리아미드아민 경화제는 여러 가지 우수한 장점에도 불구하고 수중에서 사용하기에는 불편함이 많았다. 밀도가 물보다 낮아 물에 떠오르는 것은 물론이고 친수성부분이 많음으로 인해 Micell이 형성되어 수중부착을 어렵게 했다. 일반적으로 반응성희석제로 사용되는 Monoepoxide는 에폭시수지의 점도를 조절하기 위해서 사용되고 있으며, 각각의 경화제를 변성시키기 위해서도 사용되고 있다. 이러한 점도 조절용이나 경화제 변성용으로 사용할 경우 물성변화가 일어나기 때문에 보통 10% 범위내에서 사용되어지고 있다. 또한 특2000-0068761 [습강도 열경화성 수지 포뮬레이션 및 종이 제품 제조에 사용하기에 적당한 폴리아민아미드] 에 제시한 것과 같이 폴리아미드아민을 제조 후 말단부분을 캐핑시키고 에피클로로히드린을 부가시키기 위해서도 사용되었다.Polyamideamine curing agents used in epoxy resins, despite their many excellent advantages, were inconvenient to use in water. The density is lower than that of water, as well as floating in the water, due to the large number of hydrophilic parts, Micell was formed, making it difficult to attach underwater. In general, Monoepoxide, which is used as a reactive diluent, is used to control the viscosity of epoxy resin and is also used to modify each curing agent. When it is used for viscosity adjustment or curing agent modification, it is usually used within the range of 10% because physical property changes occur. It was also used to cap the end portions and add epichlorohydrin after the preparation of polyamideamine, as described in Special 2000-0068761 [Polyamineamides Suitable for Use in Wet Strength Thermosetting Resin Formulations and Paper Products]. .
현재 수중주입용으로 사용되는 에폭시 경화제는 사이클로아민 계열과 같은 고리모형을 포함하는 종류의 제품을 주로 사용하고 있으나 Filler를 일정량이상 첨가한 경우에 있어서 수중부착력이 많이 떨어지는 문제점 때문에 사용할 수 가 없었다. 이러한 문제점으로 인해 폴리아미드아민 제품이 습한 면이나 수중용 씰링제품으로 사용하고 있는 것이 사실이다. 이러한 폴리아미드아민들은 Micell이 형성되기는 하지만 Filler를 첨가한 경우에도 다른 제품보다 부착력이 월등히 우수하기 때문이다. 그러나 Micell이 형성됨으로 인해 작업에 불편함은 물론 수질을 오염시키는 원인이 되었다.Currently, epoxy curing agent used for underwater injection mainly uses a kind of product including a cyclic model such as cycloamine series, but it could not be used because of the problem that the adhesion strength in the water drops a lot when a certain amount of filler is added. Due to these problems, it is true that polyamideamine products are used as wet cotton or underwater sealing products. Although these polyamideamines form micells, they have much better adhesion than other products even when filler is added. However, due to the formation of the Micell, not only was it inconvenient to work, but also contaminated water quality.
본 발명은 상기와 같은 문제점을 해결하기 위해 Aniline 과 2-Chloroethylaminemonohydrochloride에 의해 벤젠고리를 포함하는 새로운 아민을 제조한 후 dimer acid와 반응에 의해 아미드아민을 제조하는 방법, 알킬아민류를 알데히드나 케톤으로 1차아민을 봉쇄하고 Monoepoxide, Carboxylic acid, 산무수물, 산염화물등, 할로겐화알킬, 할로겐화알릴, 벤젠술폰산, 벤젠술폰산알킬, 염화토실등으로 2차아민을 봉쇄한 후 봉쇄된 아민을 물에 의해 1차아민으로 바꾼 후 dimer acid와 반응시키는 방법,The present invention is to solve the above problems by preparing a new amine containing a benzene ring by Aniline and 2-Chloroethylaminemonohydrochloride and a method for producing an amide amine by reaction with dimer acid, alkylamines as aldehyde or ketone 1 The secondary amine is blocked with monoamine, carboxylic acid, acid anhydride, acid chloride, alkyl halide, allyl halide, benzene sulfonic acid, alkyl benzene sulfonate, tosyl chloride, etc. Reaction with dimer acid after conversion to,
Monoepoxide, Carboxylic acid, 산무수물, 산염화물, 할로겐화알킬, 할로겐화알릴, 벤젠술폰산, 벤젠술폰산알킬등을 사용하여 폴리아미드아민 경화제의 친수성 부분인 활성수소에 일정량 결합시킴으로써 분자량을 증가시켜 활성수소당량 증가로 인해 소수성을 향상시키면 분자사이에 가교결합을 일으키지 않으면서도 물에 의해 Micell이 형성되는 것을 방지하는 것이다.Using monoepoxide, carboxylic acid, acid anhydride, acid chloride, alkyl halide, allyl halide, benzene sulfonic acid, alkyl benzene sulfonate, etc., by binding a certain amount to the active hydrogen which is the hydrophilic part of the polyamide amine curing agent, Improving the hydrophobicity is to prevent the formation of Micell by water without causing crosslinking between molecules.
일반적으로 폴리아미드아민은 Lactam ring 의 개환, diamine과 dicarboxylic acids, amino-acid의 축합중합에 의해서 만들어지는데 에폭시 경화제로 사용되는폴리아미드아민은 보통 diamine과 dicarboxylic acids에 의해서 만들어진다. 디아민 종류로는 알킬디아민, 디에틸렌트리아민, 트리에틸렌테트라아민, 테트라에틸렌펜타민, 디프로필렌트리아민과 이들 혼합물 등이 사용되며, dicarboxylic acids로는 옥살산, 말론산, 숙신산, 글루타르산, 아디프산, 피멜산, 프탈산 및 이들 각각의 이성질체와 이들 혼합물을 사용할 수 있다. 여기에 나열된 것은 일반적인 것이며 산염화물, 산무수물이나 1차아민, 2차아민에 의해서도 에폭시 경화제용 폴리아미드 아민이 만들어지고 있다.Generally polyamideamine is produced by ring opening of Lactam ring, condensation polymerization of diamine and dicarboxylic acids and amino-acid. Polyamideamine used as epoxy curing agent is usually made by diamine and dicarboxylic acids. Examples of the diamine include alkyldiamine, diethylenetriamine, triethylenetetraamine, tetraethylenepentamine, dipropylenetriamine and mixtures thereof, and dicarboxylic acids include oxalic acid, malonic acid, succinic acid, glutaric acid and adipic. Acids, pimelic acid, phthalic acid and their respective isomers and mixtures thereof can be used. Listed here are general and polyamide amines for epoxy curing agents are also made from acid chlorides, acid anhydrides, primary amines and secondary amines.

실험결과에 의해 Monoepoxides, Carboxylic acid, 산염화물, 산무수물, 할로겐화알킬, 할로겐화알릴, 벤젠술폰산, 벤젠술폰산알킬등이 중량대비 30% 미만을 첨가하여 변성시켰을때는 폴리아미드아민의 비중을 물보다 높일 수 있었지만 Micell이 형성되지 않는 것은 아니나 형성되는 속도를 느리게 할 수 있었으며 중량대비 30∼45%를 사용하여 활성수소를 치환 또는 첨가했을 때 물 속에서 폴리아미드아민의 Micell형성은 시간변화에도 나타나지 않음을 알 수 있었다.According to the experimental results, the specific gravity of polyamideamine was higher than that of water when Monoepoxides, Carboxylic acid, acid chlorides, acid anhydrides, alkyl halides, allyl halides, benzenesulfonic acids and alkyl benzenesulfonic acids were added at less than 30% by weight. Micell was not formed, but it was able to slow down the formation rate, and it was found that Micell formation of polyamideamine in water did not appear in time change when active hydrogen was substituted or added using 30-45% by weight. there was.
여기에서 중량대비 45%이상을 치환해도 Micell이 형성되지 않는 것은 당연하지만 점도증가와 활성수소의 감소로 인해 에폭시와의 경화시 현저한 물성 감소가 일어난다.It is natural that the Micell is not formed even if it is replaced by more than 45% by weight, but due to the increase in viscosity and the reduction of active hydrogen, a significant decrease in physical properties occurs when curing with epoxy.
이상에서 상술한바와 같이 본 발명은 접착력은 우수하면서도 수중에서 Micell이 형성되어 사용할 수 없는 폴리아미드아민을 물에 의해 영향을 받지 않고 사용할 수 있도록 하였다. 또한 폴리아미드아민의 우수한 접착력을 수중에서 사용하는데 있어 Micell의 형성으로 인한 수질오염원을 제거하였으며, 작업시 부유물이 떠오르지 않게 함으로써 작업에 편리함을 가져왔다.As described above, the present invention allows the polyamide amine, which is excellent in adhesion but cannot be used because Micell is formed in water, to be used without being influenced by water. In addition, in using the excellent adhesion of polyamideamine in water, the water pollution source due to the formation of Micell was removed, and it brought convenience to work by not floating the float during work.
