Description
본 발명은 폴리아미드의 제조에 있어서 나일론6, 나일론66, 나일론236의 3성분을 공중합시켜 제조됨을 특징으로 하는 융점 135℃ 미만의 저융점 폴리아미드의 제조방법에 관한 것이다.The present invention relates to a method for producing a low melting point polyamide having a melting point of less than 135 ° C., characterized by copolymerizing three components of nylon 6, nylon 66, and nylon 236 in the production of polyamide.
종래부터 핫멜트형 접착제가 여러분야에서 사용되어지고 있는데 특히 섬유업계에 있어서 봉제공업의 합리화를 위하여 섬유직물간에 분말, 에멀션, 실, 필름등 여러형태의 핫멜트형 접착제를 가압, 가열하여 접착력을 부여 함으로써 2매의 섬유직물을 접착하여 봉제하는 공정등에 사용되어지고 있다.Conventionally, hot melt adhesives have been used in all of you. In particular, in the textile industry, various types of hot melt adhesives such as powders, emulsions, yarns, and films are pressurized and heated to provide adhesion between textile fabrics. It is used in the process of bonding and sewing two textile fabrics.
일반적인 핫멜트형 접착제로서는 폴리에틸렌, 에틸렌-초산비닐 공중합체, 에틸렌-아크릴 에틸 공중합체, 폴리초산비닐, 폴리비닐부틸알 등의 합성수지의 폴리아미드가 사용되어지고 있다. 그러나 상기 섬유용 핫멜트 접착에 있어서 섬유직물간에 가압, 가열 조작에 의한 접착력의 부여로 인해 섬유직물 자체가 가열에 의해 변형되거나 열 열화 되기도하고, 핫멜트형 접착제를 고융점에서 가압하지 않으면 안되는 경우에 이러한 현상은 현저하게 발생한다.As a general hot melt adhesive, polyamides of synthetic resins such as polyethylene, ethylene-vinyl acetate copolymer, ethylene-acrylic ethyl copolymer, polyvinyl acetate, polyvinyl butylal, and the like are used. However, in the hot melt adhesive for fibers, the textile fabric itself may be deformed or thermally deteriorated by heating due to the provision of adhesion between the textile fabrics by pressing and heating operations, and the hot melt adhesive must be pressurized at a high melting point. The phenomenon occurs remarkably.
이와같은 이유로 피 접착포인 섬유직물 섬유형성재료의 융점 내지 분해온도보다 낮은 융점을 가지거나, 유동특성이 양호한 핫멜트형 접착제가 필요하게 되었다. 그러나, 저온에서 유동하는 접착제이면 가열, 압착의 공정에서 접착제가 직물의 조직중에 침투하여 접착강도를 저하 시키기도하고, 접착제가 사용된 섬유 제품을 고온에서 세탁하는 경우 등에 있어서 접착제 자체가 경화하여 접착성의 저하 및 접착제 본래의 기능을 저하시키기도 하므로 섬유직물용 핫멜트로서는 통상 융점이 100 내지 130℃정도로 유동특성이 양호하며 접착력이 높은 것이 요구되고 있다.For this reason, there is a need for a hot melt adhesive having a melting point lower than the melting point or decomposition temperature of the textile fabric fiber forming material to be bonded, or having good flow characteristics. However, if the adhesive flows at a low temperature, the adhesive penetrates into the fabric of the fabric during the heating and pressing process, thereby lowering the adhesive strength.In the case of washing the textile product in which the adhesive is used at a high temperature, the adhesive itself cures and adheres. In order to reduce the deterioration and the original function of the adhesive, the hot melt for the textile fabric is generally required to have a good flow characteristic at a melting point of about 100 to 130 ° C. and a high adhesive strength.
저융점 폴리아미드를 용이하게 얻기위해서는 공중합 또는 가소제의 첨가등을 행하고 있으나, 일반적으로 사용되고 있는 것은 나일론 공중합을 이용하는 것이다. 그러나, 나일론 6,66,610 을 공중합 시켜도 130℃미만의 저융점을 나타내기는 불가능하였다.In order to easily obtain a low melting point polyamide, copolymerization or the addition of a plasticizer is carried out, but generally used is nylon copolymerization. However, copolymerization of nylon 6,66,610 was not possible to show a low melting point of less than 130 ℃.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 에틸렌 디아민과 탄소수 36개의 식물성 지방산과의 염 (이하 나일론 236이하 한다) 25 내지 75 중량부,ε-카프로락탐 또는 ε-카프론산(이하 나일론6) 15 내지 55 중량부, 헥사메틸렌디아민과 아디프산염(이하 나일른66) 5 내지 40 중량부의 범위내에서 조정하여 공중합하면 120 내지 135℃의 저융점을 가지며 흐름성등 가공성이 우수한 폴리아미드의 제조방법을 제공하는 것이다.The present invention has been made to solve the above problems, 25 to 75 parts by weight of ethylene diamine and 36 carbon atoms of vegetable fatty acids (hereinafter referred to as nylon 236), ε-caprolactam or ε-capronic acid (hereinafter Nylon 6) 15 to 55 parts by weight, hexamethylenediamine and adipic acid (hereinafter referred to as Nile 66) when adjusted within the range of 5 to 40 parts by weight of copolymer having a low melting point of 120 to 135 ℃ and excellent workability, such as flowability It is to provide a method for producing an amide.
공중합 방법은 일반 나일론 단독 중합법의 적용이 가능하다. 즉, 소정 중량부 비율로 중합하여 무촉매상태나 알콜, 아민, 유기산, 알칼리금속 등의 존재하에 상압 또는 가압하여 250 내지 300℃로 가열 시킴으로써 목적하는 폴리아미드 수지를 얻을 수 있다.The copolymerization method is applicable to the general nylon homopolymerization method. That is, the desired polyamide resin can be obtained by polymerization at a predetermined weight part ratio and heating to 250 to 300 ° C. under normal pressure or pressure in the absence of a catalyst or in the presence of alcohols, amines, organic acids, alkali metals and the like.
본 발명에 의해 얻어지는 폴리아미드 수지는 낮은 온도 및 냉각후에 높은 결합력을 가지며 화학적 드라이크리닝제에 대해서 높은 저항력을 가진다. 또한, 방사하여 파이버상태 또는 압출성형하여 필름상으로 심지에 응용되기도하나 분말상이라도 저융점에서 성형성이 양호하므로 전기 다리미등에 의해 간단하게 접착될 수 있고, 알콜등에 가용성이므로 용액상으로 접착에 응용해도 좋다.The polyamide resin obtained by the present invention has a high bonding strength after low temperature and cooling and high resistance to chemical dry cleaning agents. In addition, it can be applied to a wick in the form of a fiber or extrusion by spinning, but even in powder form, it has good moldability at low melting point, so it can be easily adhered by an electric iron or the like. good.
