상기와 같은 기술적 과제를 달성하기 위하여, 본 발명은 주제와 경화제로 구성되는 직포 또는 부직포의 기계적 물성 및 자기소화성 강화 조성물과 이를 함침한 직포 또는 부직포를 제공한다.In order to achieve the above technical problem, the present invention provides a mechanical property and a self-extinguishing reinforcing composition of the woven or nonwoven fabric consisting of the subject and the curing agent and a woven or nonwoven fabric impregnated therewith.
1. 주제와 경화제로 이루어진 조성물 1. Composition consisting of Molecular and Curing Agent
본 발명의 직포 또는 부직포 함침용 조성물은 주제와 경화제로서 구성된다. 이러한 주제와 경화제는 폴리올의 수산기(-OH) 당량 : 경화제의 NCO 당량 비율은 0.8 ~ 1.2 : 1.2 ~ 0.8 당량으로 한다. 아울러 본 발명에 있어 유기 고분자 조성물은 주제와 경화제가 혼합된 것으로 건조가 빠르며, 직포나 부직포의 인장 강도 및 신장율을 증강시켜 주며 화염에 닿아도 쉽게 불붙지 않게 하는 자기 소화성 특징을 부여하는 조성물이다.The composition for woven or nonwoven fabric impregnation of the present invention is composed of a main agent and a curing agent. Such a main ingredient and the curing agent are the hydroxyl group (-OH) equivalents of the polyol: the NCO equivalent ratio of the curing agent is 0.8 to 1.2: 1.2 to 0.8 equivalents. In addition, in the present invention, the organic polymer composition is a mixture of a main agent and a curing agent, which is fast to dry, enhances tensile strength and elongation of a woven or nonwoven fabric, and provides a self-extinguishing feature that does not easily ignite when touched by a flame.
또한, 본 발명의 경우, 직포나 부직포의 중량에 따라 유기 고분자 조성물의 함량(중량)은 달라 지게 된다. 바람직하게는, 평균적으로 130g/㎡기준으로 할 때 유기 고분자 조성물은 450g/㎡ ~ 700g/㎡이 소요되는데, 이렇게 함침시킨 직포나 부직포는 함침시키지 않는 직포나 부직포에 비해 인장 강도와 신장율이 이하의 실시예에서 보는 바와 같이 월등히 높아지게 된다. 또한 이는 반응성 합성수지이므로 기존에 주로 하도나 상도에 사용하는 에폭시(Epoxy) 화합물, 우레탄 화합물과의 층간 접착력이 매우 우수하다. 이하 주제와 경화제의 구성을 보다 상세하게 설명한다.In addition, in the case of the present invention, the content (weight) of the organic polymer composition varies depending on the weight of the woven or nonwoven fabric. Preferably, on the basis of the 130g / ㎡ standard, the organic polymer composition takes 450g / ㎡ ~ 700g / ㎡, the impregnated woven fabric or nonwoven fabric is less than the tensile strength and elongation compared to woven or nonwoven fabric not impregnated As shown in the embodiment, it is much higher. In addition, since it is a reactive synthetic resin, it is very excellent in the adhesive strength between layers with epoxy compounds and urethane compounds that are mainly used in the existing coat or top coat. Hereinafter, the configuration of the subject and the curing agent will be described in more detail.
(1)주제 (1) Topics
주제는 피마자유 또는 수산화알루미늄(Aluminum Hydroxide), 멜라민(Melamine), 펜타에리트리톨(Pentaerythritol), 인산암모늄(Ammonium Phosphate), 디시안디아마이드(Dicyandiamide)를 포함하여 구성되고, 경화제는 씨-엠디아이(C-MDI; Crude 4,4'-Diphenylmethane Diisocyanate)나 폴리머릭 엠디아이(Polymeric MDI; Polymeric 4,4'-Diphenylmethane diisocyanate)로 구성된다.Subjects include castor oil or Aluminum Hydroxide, Melamine, Pentaerythritol, Ammonium Phosphate, Dicyandiamide, and hardeners C-MDI; Crude 4,4'-Diphenylmethane Diisocyanate) or Polymeric MDI; Polymeric 4,4'-Diphenylmethane diisocyanate.
1)피마자유 1) Castor oil
본 발명은 종래에 에칠렌 글리콜류나 프로필렌 글리콜류의 부가반응에 의한 에테르 폴리올과 유기산과 알콜류의 에스테르 반응에 의한 폴리에스테르 폴리올의 수산기(-OH기)와 R-NCO(이소시아네이트(isocyanate)류)와의 반응에 의한 우레탄 결합을 사용하던 것과 달리 폴리올류를 주로 사용하지 않고 피마자유의 수산기 라디칼(OH radical)을 이용하는 방법으로 불건성유인 피마자유 중에서 함유되어 있는 수산기(hydroxy group)를 R-NCO(이소시아네이트(isocyanate)류)와 반응시켜 우레탄 결합(R-NHCOO-)을 만들어 우레탄이 가지고 있는 특성을 유지하면서 그 특성을 발휘하는 것에 그 특징이 있다.The present invention is conventionally a reaction between the hydroxyl group (-OH group) and R-NCO (isocyanate) of a polyester polyol by ester reaction of an ether polyol and an organic acid and an alcohol by addition reaction of ethylene glycol or propylene glycol. Unlike using urethane bonds, the hydroxy group contained in castor oil, which is dry, is not R-NCO (isocyanate). ) To form a urethane bond (R-NHCOO-), and to exhibit the properties while maintaining the properties of the urethane.
이러한 방법을 이용하는 이유는 본 발명에 있어 주제로 사용되는 피마자유는 대부분의 기름이나 유지와 달리 불에 쉽게 연소 되지 않기 때문에 피마자유의 수산기(hydroxy group)를 이용하여 우레탄 결합에 의한 물질을 직포나 부직포에 함침시켜 인장 강도를 증진시키고 아울러 강인함과 유연성은 물론 자기소화성까지 부가하여 부직포가 쉽게 타버리는 약점을 극복할 수 있기 때문이다. 아울러 피마자유는 인공물질이 아닌 천연물질인바 환경친화적인 건축자재 등의 복합재로서의 부직포 제공을 위한 목적에 부합한다.The reason for using this method is that castor oil, which is used as a subject in the present invention, is not easily burned by fire unlike most oils or fats and oils, and thus it is woven or nonwoven fabric by using a hydroxy group of castor oil. This is because impregnation can increase the tensile strength and add strength, flexibility and self-extinguishing to overcome the weakness of the nonwoven fabric easily burned out. In addition, castor oil is a natural material rather than an artificial material, which is suitable for the purpose of providing a nonwoven fabric as a composite material such as environmentally friendly building materials.

직포 또는 부직포를 알코올 램프의 불꽃 5cm 위에 놓아 보았다.A woven or nonwoven fabric was placed 5 cm above the flame of the alcohol lamp.
상기 표에서 보는 바와 같이 일반 직포나 부직포는 바로 연소 되는 반면, 본 발명의 조성물로 함침한 직포 또는 부직포는 7초가 지나도 타지 않고, 불에 닿지 않는 상부는 외형의 변화가 없었고, 불을 제거하였을 때 그을렸을 뿐 연소가 되지 않았음을 알 수 있었다.As shown in the table above, the normal woven fabric or nonwoven fabric is burned immediately, while the woven fabric or nonwoven fabric impregnated with the composition of the present invention does not burn after 7 seconds, and the upper part which does not touch the fire has no change in appearance, when the fire is removed. It was only burned and found no burning.
실시 예2)Example 2
조성물의 유기 고분자 합성수지에 자기 소화성을 더욱 향상시키기 위해 다음과 같은 조성물로 함침시켜 건조시켜 보았다.The organic polymer synthetic resin of the composition was impregnated with the following composition to further improve self-extinguishing and dried.
(건조 조건 80℃ ~ 100℃ 열풍 5 ~ 10분)(Drying condition 80 degrees Celsius-100 degrees Celsius hot air 5-10 minutes)
위 배합으로 주제와 경화제의 비율은 3 : 1로 혼합함침 시킨 후, Roller로 잘 짜서 함침액을 일정하게 만든 후(600g/㎡) 이형지가 있는 Roll에 감았다. 그 결과 인장 강도와 신장율은 별 차이가 없으나 내화 기능이 뛰어나 불에 닿았을 때 닿은 부분은 발포가 되어 (200 ~ 300%) 불에 타지 않았다.After mixing and impregnating the ratio of the main agent and the hardener to 3: 1 by the above formulation, the impregnating solution was uniformly squeezed with a roller (600g / ㎡) and wound on a roll with release paper. As a result, there was no difference in tensile strength and elongation, but because of its excellent fire resistance, the touched part was foamed (200-300%) and did not burn.

실시 예3)Example 3
실시 예 1을 함침시킨 후 건조시키기 전에 폴리에스테르 필름 12㎛ ~ 16㎛의 두께로 한 면을 접착시킨 후 제품을 만들어 완전 방수층을 만들어 표면이 전혀 흡수되지 않는 필름으로 코팅시켰다.After impregnating Example 1 and before drying, one side of the polyester film was bonded to a thickness of 12 μm to 16 μm, and then a product was made to form a completely waterproof layer and coated with a film whose surface is not absorbed at all.
이와 같이 폴리에스테르필름을 코팅시킨 직포 또는 부직포는 차수 효과가 아주 뛰어나고 복합구조(바닥재,방수재)에 아주 유용한 소재로 활용된다.The woven or nonwoven fabric coated with the polyester film is excellent in ordering effect and is used as a very useful material for composite structures (floors, waterproofing materials).
본 실시예에서는 본 발명의 조성물을 함침한 직포 또는 부직포와 이것의 일면에 12㎛~16㎛ 두께의 폴리에스테르 필름을 부착한 것의 차수성 및 접착력을 비교하여 보았다.In this example, the order and adhesion of the woven or nonwoven fabric impregnated with the composition of the present invention and a polyester film having a thickness of 12 μm to 16 μm were attached to one surface thereof were compared.
본 발명은 직포 또는 부직포 함침용 조성물 및 이를 함침한 직포 또는 부직 포에 대한 것이다. 본 발명의 직포 또는 부직포 함침용 조성물은 천연물질인 피마자유를 이용하여 우레탄 결합을 만드는 2액형의 특수고분자 물질로서, 이를 일반적인 직포나 부직포에 함침할 경우 인장강도 및 신장율 향상의 효과를 갖게 되며, 아울러 자기 소화성 및 난연기능을 갖게 된다. The present invention relates to a composition for woven or nonwoven fabric and a woven or nonwoven fabric impregnated therewith. Composition for impregnating woven or nonwoven fabric of the present invention is a two-component special polymer material that makes urethane bonds using castor oil, which is a natural material, and when it is impregnated with a general woven or nonwoven fabric, it has an effect of improving tensile strength and elongation rate. In addition, it has self-extinguishing and flame retardant function.
이러한 본 발명의 조성물을 함침한 직포 또는 부직포는 건축분야의 방수재에 삽입하는 직포 또는 부직포로 사용되거나 도장재에 우수한 층간 접착력을 가진 특성을 활용하여 복합기재의 하나로 사용할 수 있다.The woven fabric or nonwoven fabric impregnated with the composition of the present invention may be used as a woven fabric or a nonwoven fabric inserted into a waterproofing material in a building field, or may be used as one of composite materials by utilizing properties having excellent interlayer adhesion to a coating material.
아울러, 본 발명의 조성물에 있어 주제로 사용되는 피마자유는 인공물질이 아닌 천연물질인바 본 발명의 조성물로 함침한 직포 또는 부직포는 환경친화적인 건축자재 등의 복합재로서 사용하기에 적합하다.In addition, castor oil used as a subject in the composition of the present invention is a natural material rather than an artificial material, so woven or nonwoven fabric impregnated with the composition of the present invention is suitable for use as a composite material such as environmentally friendly building materials.
또한 일반 직포 또는 부직포를 단순히 사용하는 것에 비교하여 본 발명의 조성물을 함침한 직포 또는 부직포는 흡유량이 없어 복합재로서의 사용시 성능향상 및 공기 단축 등의 효과가 있어 경제성이 우수한 효과가 있다.In addition, compared with simply using a general woven or nonwoven fabric, the woven fabric or nonwoven fabric impregnated with the composition of the present invention has no oil absorption amount, and thus has an effect of improving performance and shortening of air when used as a composite material, thereby having excellent economic efficiency.
