The present invention relates to a flame retardant board made of an epoxy resin, a titanium composite having an epoxy reactor, and a non-halogen flame retardant to improve flame retardancy and mechanical properties.
점차 지구 환경과 에너지 절감에 대한 연구가 많이 이루어지고 있는 가운데 친환경적인 산업개발과 이에 따른 신소재의 연구들이 활발히 이루어지고 있으며, 이와 더불어 재해 방지 제품에 대한 연구 개발 역시 활발히 이루어지고 있다.
As researches on the global environment and energy saving are progressing gradually, researches on environment - friendly industrial development and new materials have been actively carried out. In addition, research and development on disaster prevention products are being actively carried out.
이에 최근에 이슈가 되는 에너지 절감 및 재해 방지 차원에서 난연성을 높이고 화재시 연기와 화염으로부터 많은 인명과 재산을 보호할 수 있는 난연 보드 관련 기술 개발이 활발히 진행되고 있다.
Recently, development of flame retardant board related technology that can increase flame retardance and prevent many people and property from smoke and flames in case of fire has been actively developed in order to reduce energy consumption and disaster prevention.
일반적으로 사용되는 난연보드는 석면 또는 유리솜, 스티로폼 등이 주로 사용되고 있으며, 석면은 광석으로부터 얻어지는 것으로 그 원가가 저렴하고 난연효과가 우수하지만 일급 발암물질로서 건축물의 철거시 폐기물을 생성하고 주변환경을 오염시키는 등의 많은 문제점이 있어 그 사용이 금지되고 있다.
Asbestos, glass wool and styrofoam are commonly used, and asbestos is obtained from ore. Its cost is low and its flame retardant effect is excellent. However, it is a primary carcinogen, There are many problems such as disabling the use thereof.
그리고 유리솜은 솜에 유리가루를 배합하여 제조하는 것으로서 난연성이 우수하여 석면을 대신하여 널리 사용되고 있지만, 그 생산 원가가 높고 재활용이 불가능하며 취급과정에 있어 작업자의 피부 등이 유리에 의해 쉽게 손상되어 취급이 용이하지 않는 등 그 사용에 많은 문제점이 있다.
Glass wool is produced by blending glass flour with cotton, and it is widely used instead of asbestos because of its excellent flame retardancy. However, its production cost is high and it can not be recycled. In the handling process, the skin of worker is easily damaged by glass There are many problems in its use.
또한, 스티로폼은 가볍고 생산원가가 저렴하여 널리 사용되고 있지만 난연성이 미비하여 화재에 매우 취약한 문제점이 있었다.
In addition, styrofoam is widely used because it is light in weight and low in production cost, but its flame retardancy is insufficient and it is very vulnerable to fire.
따라서, 최근에는 질석, 규조토, 진주암, 황토, 맥반석 등을 유기 결합제 혹은 무기 결합제로 결합하여 난연 보드로 제조하고 있는 추세이지만, 이 또한 생산 비용과 경제성에 있어서 아직 많은 활성화가 되지 못하고 있다.
Therefore, recently, vermiculite, diatomaceous earth, perlite, loess, and quartzite are combined with an organic binder or an inorganic binder to manufacture a flame retardant board, but this has not yet been activated in terms of production cost and economy.
이를 해결하기 위하여, 특허문헌 1에서는 중공 실리카 입자를 포함하는 난연성 시트를 제안하였으나, 상기 중공 실리카 입자와 베이스 수지에 대한 분산성이 미비하여 중공 실리카 입자에 의한 난연성이 충분히 발휘되지 못하는 문제점이 있었다.
In order to solve this problem, Patent Document 1 proposes a flame retardant sheet including hollow silica particles, but the dispersibility of the hollow silica particles and the base resin is insufficient and the flame retardancy due to the hollow silica particles can not be sufficiently exhibited.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 에폭시 수지, 에폭시 반응기를 갖는 티타늄 복합체 및 비할로겐계 난연제를 혼합하여 난연 보드를 제조함으로써, 티타늄 복합체의 분산성이 향상됨에 따라 그 난연성 및 기계적 물성을 극히 향상시킬 수 있도록 함을 과제로 한다.

상기 티타늄 복합체는 난연 보드의 난연성 및 기계적 물성을 향상시키기 위해 첨가되는 것으로, 다음과 같이 제조되어 아래 (화학식 1)과 같이 에폭시 반응기를 가진다.
The titanium composite is added to improve the flame retardancy and mechanical properties of the flame retardant board. The titanium composite is prepared as follows and has an epoxy reactor as shown in the following formula (1).
먼저, 이소시아네이트와 반응할 수 있는 머캅토기, 아미노기, 알콜기, 에폭시기 등의 비공유 전자쌍을 갖고 있는 화합물을 포함하는 알콕시티타늄과 디이소시아네이트를 상온 ~ 80℃의 반응온도에서 반응시켜 말단 이소시아네이트기를 포함하는 티탄 화합물을 제조한다. 그 다음 연속해서 히드록시기를 포함하는 에폭시 화합물을 투입하고 50 ~ 100℃로 승온하여 1 ~ 5시간 동안 이소시아네이트가 모두 반응할 때까지 교반해서 에폭시기를 포함하는 티타늄 복합체를 제조한다.
First, an alkoxy titanium containing a compound having a pair of non-covalent electrons such as a mercapto group, an amino group, an alcohol group and an epoxy group capable of reacting with isocyanate is reacted with a diisocyanate at a reaction temperature of room temperature to 80 ° C to obtain a titanium compound having a terminal isocyanate group ≪ / RTI > Subsequently, an epoxy compound containing a hydroxyl group is continuously added, the temperature is raised to 50 to 100 ° C, and the mixture is stirred for 1 to 5 hours until all of the isocyanates react to prepare a titanium complex containing an epoxy group.
그리고, 에폭시기 말단의 알콕시 티탄 복합체에 알콕시기를 3개 이상 포함하는 티탄 화합물을 병용하고 물을 투입한 다음 촉매로 0.1N HCl 수용액을 첨가하여 pH를 5로 조절한 다음 상온에서 하루 동안 교반하여 가수분해, 응축과정을 거쳐서 아래 (화학식 1)과 같은 에폭시기를 포함하는 티타늄 복합체를 제조한다.
Then, a titanium compound containing three or more alkoxy groups was added to the alkoxytitanium complex at the end of the epoxy group, and water was added thereto. Then, a 0.1 N aqueous HCl solution was added to adjust the pH to 5, and the mixture was stirred at room temperature for one day, , And a condensation process is carried out to prepare a titanium complex containing an epoxy group such as the following formula (1).
한편, 에폭시 복합체 제조시에는 모리큐라시브(molecular sieve)로 물과 용매를 제거한 다음 사용한다.
On the other hand, when preparing epoxy composites, water and solvent are removed with a molecular sieve before use.
(화학식 1)(Formula 1)
상기 (화학식 1)에서 T는 알콕시티탄으로부터 합성된 이산화티탄 화합물이고, R은 C1~C20의 지방족, 지환족 또는 방향족 알킬기이며, n은 2이상의 정수이다.
T is a titanium dioxide compound synthesized from alkoxytitanium, R is a C1-C20 aliphatic, alicyclic or aromatic alkyl group, and n is an integer of 2 or more.
한편, 상기와 같은 티타늄 복합체는 에폭시 수지 100 중량부에 대하여, 50 ~ 100 중량부 사용하는 것이 바람직하며, 50 중량부 미만에서는 난연성 및 기계적 물성의 향상효과가 미비해질 우려가 있고, 100 중량부를 초과할 경우, 난연 보드의 성형이 제대로 이루어지지 않을 우려가 있다.
On the other hand, the titanium complex is preferably used in an amount of 50 to 100 parts by weight based on 100 parts by weight of the epoxy resin. When the amount is less than 50 parts by weight, the effect of improving flame retardancy and mechanical properties may be insufficient. There is a possibility that the molding of the flame-retardant board may not be performed properly.
상기 비할로겐계 난연제는 난연 보드에 대한 난연성을 더욱 향상시키기 위해 첨가되는 것으로, 인산암모늄, 탄산암모늄, 트리아딘 화합물, 멜라민시아누레이트, 구아니딘화합물과 같은 질소계 난연제 또는 수산화마그네슘, 수산화 알루미늄과 같은 금속수산화물 또는 멜라민폴리포스페이트, 암모늄폴리포스페이트, 디암모늄포스페이트, 모노암모늄포스페이트, 폴리인산아미드, 인산아미드, 멜라민포스페이트, 레드포스페이트와 같은 인계 난연제를 단독 또는 병용하여 사용한다.
The non-halogen flame retardant is added to further improve the flame retardancy of the flame retardant board. Examples of the non-halogen flame retardant include nitrogen-based flame retardants such as ammonium phosphate, ammonium carbonate, triazine compounds, melamine cyanurate and guanidine compounds, Metal hydroxide or a phosphorus flame retardant such as melamine polyphosphate, ammonium polyphosphate, diammonium phosphate, monoammonium phosphate, polyphosphoric acid amide, phosphoric acid amide, melamine phosphate, and red phosphate is used alone or in combination.
이때, 상기 비할로겐계 난연제는 에폭시 수지 100 중량부에 대하여, 10 ~ 20 중량부를 사용하는데, 비할로겐계 난연제의 사용량이 10 중량부 미만일 경우, 난연성의 향상효과가 미비해질 우려가 있으며, 20 중량부를 초과할 경우, 난연 보드의 기계적 물성이 저하될 우려가 있다.
In this case, the non-halogen flame retardant is used in an amount of 10 to 20 parts by weight based on 100 parts by weight of the epoxy resin. When the amount of the non-halogen flame retardant is less than 10 parts by weight, the effect of improving the flame retardancy may be insufficient. The mechanical properties of the flame retardant board may deteriorate.

난연성은 UL 94 수직연소시험 규격에 준하여 평가하였다. 시편을 장치하고 버너로 10초간 불을 붙인 후 버너를 제거하고 시편에 붙은 불이 꺼지기까지의 시간, 연기발생정도, 무게감소율(%) <(초기시편무게-난연평가 후 시편무게)/초기시편무게×100)>, 난연등급을 측정하였다.
Flammability was evaluated in accordance with UL 94 vertical combustion test standard. After the specimen has been set and the burner has been turned on for 10 seconds, the burner is removed and the time until the fire on the specimen is turned off, the degree of smoke generation and the weight loss rate (%) <(initial specimen weight - specimen weight after flame retardant evaluation) Weight x 100) >, and the flame retardancy grade was measured.
