본 발명은 친환경성 복합재료를 적층한 난연, 내열, 내마모성, 고무 변성 에폭시 수지-카본 섬유의 프리프레그 제조용 에폭시 수지에 관한 것이다. 프리프레그 제조용 에폭시 수지는, 통상 원료로 사용되는 에폭시 수지와 최종 산물인 에폭시 수지가 동일하게 에폭시 수지로 불려지고 있다. 따라서 본 발명에서는 원료로 사용되는 에폭시 수지를 기초 에폭시 수지라 하고, 기초 에폭시 수지에 에폭시 경화제와 난연제 등이 혼합되어 만들어진 프리프레그 제조용 에폭시 수지를 최종 에폭시 수지라 칭하여 서로 구별하기로 한다.The present invention relates to an epoxy resin for prepreg production of flame-retardant, heat-resistant, abrasion-resistant, rubber-modified epoxy resin-carbon fibers laminated with environmentally friendly composite materials. As for the epoxy resin for prepreg manufacture, the epoxy resin normally used as a raw material and the epoxy resin which is a final product are called the epoxy resin similarly. Therefore, in the present invention, an epoxy resin used as a raw material is called a basic epoxy resin, and an epoxy resin for preparing prepreg made by mixing an epoxy curing agent and a flame retardant with the basic epoxy resin will be referred to as a final epoxy resin.

우선, 본 발명은 무용제형과 용제형의 두 가지 타입의 최종 에폭시 수지로 실시할 수 있다. 그리고 각각의 타입마다 두 가지의 실시예를 가진다.First, the present invention can be carried out with two types of final epoxy resins, a solventless type and a solvent type. Each type has two embodiments.

첫째로, 무용제형의 경우는 다음과 같다.First, the solvent-free type is as follows.

무용제형의 최종 에폭시 수지는 기초 에폭시 수지와, 에폭시 경화제와, 난연제로 구성된다The solventless final epoxy resin is composed of a basic epoxy resin, an epoxy curing agent, and a flame retardant.

상기와 같은 기초 에폭시 수지와, 에폭시 경화제와, 난연제가 혼합되어 구성된 프리프레그 제조용 에폭시 수지에 있어서, 본 발명은 기초 에폭시 수지와 난연제의 구성에 특징이 있다.In the epoxy resin for prepreg manufacture in which the above-mentioned base epoxy resin, an epoxy hardening | curing agent, and a flame retardant were mixed, this invention is characterized by the structure of a base epoxy resin and a flame retardant.

우선, 기초 에폭시 수지의 제 1실시예는 KDP-550MC65 30~42중량％와, YDCN-500-90PA75 53~63중량％와, KR-450 3~9중량％로 구성된다. 따라서 제 1실시예의 기초 에폭시 수지와, 종래와 같은 경화제 및 난연제가 종래와 같은 비율로 혼합되어 프리프레그 제조용 에폭시 수지인 최종 에폭시 수지가 된다.First, the first embodiment of the base epoxy resin is composed of 30 to 42% by weight of KDP-550MC65, 53 to 63% by weight of YDCN-500-90PA75, and 3 to 9% by weight of KR-450. Accordingly, the basic epoxy resin of the first embodiment, the conventional curing agent and the flame retardant are mixed in the same ratio as in the prior art to form the final epoxy resin which is the epoxy resin for prepreg production.

통상의 경화제와 난연제는 각각 최종 에폭시 수지에 대하여 1~5중량％와 2~10중량％ 사용된다. 이는 공지된 비율이므로 상세한 설명은 생략하고, 또한 상기의 범위를 벗어나는 구성비가 있을 수도 있다.A normal hardening agent and a flame retardant are used 1 to 5 weight% and 2 to 10 weight% with respect to final epoxy resin, respectively. Since this is a known ratio, a detailed description thereof will be omitted, and there may be a configuration ratio outside the above range.

그리고 기초 에폭시 수지의 제 2실시예는 KDP-555MC80 32~42중량％와, KBPN-120 50~62중량％와, R-13095 4~10중량％로 구성된다The second embodiment of the base epoxy resin is composed of 32 to 42% by weight of KDP-555MC80, 50 to 62% by weight of KBPN-120, and 4 to 10% by weight of R-13095.

상기와 같은 각 실시예에서 가장 이상적인 난연제를 구성할 수 있다. 본 발명의 난연제는 기초 에폭시 수지의 제 1실시예 또는 제 2 실시예 어느 경우에라도 동일하게 사용될 수 있는 것으로, FR-3700 100중량％를 사용하거나, Al(OH)3 100중량％를 사용할 수 있다. 또는 FR-3700 52~62중량％와, Al(OH)3 38~48중량％로 구성하여 사용할 수도 있다.In each of the above embodiments it can be configured the most ideal flame retardant. The flame retardant of the present invention can be used in the same manner in any of the first or second embodiment of the base epoxy resin, and 100% by weight of FR-3700 or 100% by weight of Al (OH) 3 can be used. . Or you may use it comprised from 52-62 weight% of FR-3700, and 38-48 weight% of Al (OH) 3 .

상기와 같은 난연제의 선택과 혼합비가 본 발명의 목적에 가장 부합되는 결과를 가져 온다.The selection and mixing ratio of the flame retardant as described above results in the most suitable for the purpose of the present invention.

상기와 같이 본 발명은 기초 에폭시 수지로서 종래의 할로겐 원소 화합물인 Brominated epoxy resin 대신에 KDP-550MC65와 KDP-555MC80가 사용되고; 기초 에폭시 수지의 성분으로서 고온에 견디도록 하는 성분인 o-Cresol Novolac형 Epoxy 수지인 YDCN-500 series, 특히 YDCN-500-90PA75와, BPA-Novolac형 Epoxy 수지, 특히 KBPN-120이 사용되며; 난연재로서 산화 Antimonium 대신에 인계(燐系) 무기 친환경성 난연제인 FR-3700와 수산화 Alumium(Al(OH)3)이 사용된다. 따라서 종래와 동일한 난연효과를 얻음과 동시에 인체에 무해한 친환경적인 카본섬유 프리프레그용 최종 에폭시 수지가 된다.As described above, in the present invention, KDP-550MC65 and KDP-555MC80 are used as the base epoxy resin instead of the conventional halogenated epoxy resin Brominated epoxy resin; As the components of the basic epoxy resin, YDCN-500 series, especially YDCN-500-90PA75, which is an o-Cresol Novolac-type Epoxy resin which is resistant to high temperatures, and BPA-Novolac-type Epoxy resin, in particular KBPN-120, are used; Instead of antimonium oxide, FR-3700 and Alumium hydroxide (Al (OH) 3 ), which are phosphorus inorganic eco-friendly flame retardants, are used as flame retardants. Therefore, while obtaining the same flame retardant effect as in the prior art, the final epoxy resin for environmentally friendly carbon fiber prepreg is harmless to humans.

그리고 기초 에폭시 수지의 구성 성분으로서, 고무 변성의 특징을 나타내는 rubber modified(고무변성) Epoxy Resin은 KR series 특히 KR-450을 사용하거나, 또는 R-1309 Epoxy Resin을 사용한다. 따라서 이의 첨가로 내충격성과 내마모성의 특성이 향상된다. rubber 변성 type으로는 CTBN(Carboxyl Terminal Butadien Acrylnitrile)와 NBR Acrylic도 가능하다.And as a constituent of the base epoxy resin, rubber modified Epoxy Resin, which shows the characteristics of rubber modification, uses KR series, especially KR-450, or R-1309 Epoxy Resin. Therefore, the addition thereof improves the properties of impact resistance and wear resistance. Rubber modified types are also available as CTBN (Carboxyl Terminal Butadien Acrylnitrile) and NBR Acrylic.

복합소재에서 요구되는 접촉강도, 신율, 적층간 접착강도, 내마모성, 내충격성 등의 향상을 위하여 다목적 Epoxy-Carbon composite material이 필연적인다. 특히 난연성에 있어서는 친환경성(non-halogen Flame-retardant epoxy Resin) Epoxy Resin과, 친환경성 인계 난연제가 첨가됨으로써 한층 더 좋은 효과를 가져오게 된다.In order to improve the contact strength, elongation, inter-lamination adhesive strength, abrasion resistance, and impact resistance required in composite materials, a multi-purpose epoxy-carbon composite material is inevitable. In particular, in the flame retardant (non-halogen Flame-retardant epoxy Resin) Epoxy Resin and environmentally friendly phosphorus-based flame retardant is added to bring a better effect.

지금까지 사용해 온 난연제로서는 Halogene 원소가 함유된 Brominated Epoxy Resin 또는 Decabromodipheny Oxide와, 체질재로서는 산화 Antimonium Chlorium 화합물 등이었다.Flame retardants used so far include brominated epoxy resins or decabromodipheny oxides containing halogene elements, and antimonium chloride compounds as sieving materials.

이러한 화합물 또는 체질재는 화재발생시 유독가스를 분출하여 많은 인명 피해를 일으키게 된다. 따라서 본 발명은 기초 에폭시 수지로 친환경성 난연제 non-Halogen Flame-retardant Epoxy Resin인 KDP series와, 난연재로서 인계 FR-3700와 수산화 Alminium를 사용한다.Such compounds or constituents cause a lot of human injury by releasing toxic gases in the event of fire. Therefore, the present invention uses the KDP series of environmentally friendly flame retardant non-Halogen Flame-retardant Epoxy Resin as the basic epoxy resin, and phosphorus-based FR-3700 and Alminium hydroxide as the flame retardant.

그리고 고온형 Epoxy Resin인 My-720은 고온성이나 구조가 polyfunctional epoxy이므로 가격이 고가이고 수입하기 어려우며 또 저장이 좋지 않다. 따라서 본 발명에 사용되는 고온형 Epoxy resin은 YDCN-500-90PA75 또는 KBPN-120를 사용한다.My-720, a high-temperature epoxy resin, has high temperature and polyfunctional epoxy structure, which is expensive, difficult to import, and poorly stored. Therefore, the high temperature epoxy resin used in the present invention uses YDCN-500-90PA75 or KBPN-120.

이러한 여러가지 화합물을 혼합한 최종 에폭시 수지를 카본섬유에 코팅하면 친환경성의 프리프레그를 제조할 수 있는 것으로, 카본섬유의 물리적 특성에 상기의 복합소재의 특성에 의해 최상의 카본섬유 프리프레그를 얻을 수 있다.When the final epoxy resin mixed with these various compounds is coated on carbon fiber, an environmentally friendly prepreg can be produced, and the best carbon fiber prepreg can be obtained by the physical properties of the carbon fiber and the properties of the composite material.

기초 에폭시 수지의 구성 요소인 경화제는 dicyandiamide이고, 경화촉진제로 Imidazole(2MI) series를 사용할 수 있다. 그리고 상기 경화제와 경화촉진제 용매는 Dimethyl-formamide, methyl cellusolve이다. 상기의 경화제와 경화촉진제의 구성비는 공지의 것으로 상세한 설명은 생략한다.The curing agent, which is a component of the basic epoxy resin, is dicyandiamide, and the Imidazole (2MI) series can be used as a curing accelerator. And the curing agent and curing accelerator solvent is Dimethyl-formamide, methyl cellusolve. The composition ratio of the said hardening | curing agent and a hardening accelerator is well-known, and detailed description is abbreviate | omitted.

상기의 구성 요소들을 모두 포함하여, 크게 기초 에폭시 수지, 경화제, 난연재로 구분할 수 있고, 그 구성비를 보면 기초 에폭시 수지 82~92중량％, 경화제 1.5~3중량％, 난연재 6~12중량％이다. 이의 구성비는 일반적인 공지의 것이다.Including all of the above components, it can be largely divided into a base epoxy resin, a curing agent, a flame retardant, the composition ratio of the base epoxy resin is 82 to 92% by weight, a curing agent 1.5 to 3% by weight, flame retardant 6 to 12% by weight. Its composition ratio is generally known.

상기에서는 무용제형의 첫번째 실시예를 설명하였다. 이하에서는 용제형의 실시예를 설명하고자 한다.In the above, the first embodiment of the non-solvent type has been described. Hereinafter will be described an embodiment of the solvent type.

둘째로, 용제형의 경우는 다음과 같다.Second, the solvent type is as follows.

용제형의 최종 에폭시 수지는 기초 에폭시 수지 62~75중량％, 경화제 1~3중량％, 난연제 5~11중량％, 용재 15~25중량％로 구성된다. 이의 구성비는 일반적인 것이다.The solvent-type final epoxy resin consists of 62-75 weight% of base epoxy resins, 1-3 weight% of hardening | curing agents, 5-11 weight% of flame retardants, and 15-25 weight% of solvents. Its composition ratio is general.

여기서 본 발명의 특징은 첫번째 실시예에서와 같이 기초 에폭시 수지의 구성에 있다. 즉, 기초 에폭시 수지의 제 1실시예는 KDP-550MC65 30~42중량％와, YDCN-500-90PA75 53~63중량％와, KR-450 3~9중량％로 구성된다.The feature of the invention here lies in the construction of the base epoxy resin as in the first embodiment. That is, the 1st Example of a basic epoxy resin consists of 30-42 weight% of KDP-550MC65, 53-63 weight% of YDCN-500-90PA75, and 3-9 weight% of KR-450.

그리고 기초 에폭시 수지의 제 2실시예는 KDP-555MC80 25~41중량％와, KBPN-120 55~67중량％와, R-13095 4~10중량％로 구성된다.The second embodiment of the base epoxy resin is composed of 25 to 41 wt% of KDP-555MC80, 55 to 67 wt% of KBPN-120, and 4 to 10 wt% of R-13095.
