본 발명은 폴리우레탄 폼의 난연화를 위한 친환경 난연제의 고속 증착 방법 및 이에 의하여 제조된 친환경 난연 폴리우레탄 폼에 관한 것으로, 보다 상세하게는 난연 처리를 위한 공정 소요 시간이 단축될 수 있도록 하면서도 유독 가스의 발생이 저감될 수 있도록 한 폴리우레탄 폼의 난연화를 위한 친환경 난연제의 고속 증착 방법 및 이에 의하여 제조된 친환경 난연 폴리우레탄 폼에 관한 것이다.The present invention relates to a high-speed deposition method of an eco-friendly flame retardant for flame-retardant polyurethane foam and an eco-friendly flame-retardant polyurethane foam manufactured thereby, and more particularly, to a toxic gas while reducing the process time for flame-retardant treatment It relates to a high-speed deposition method of an eco-friendly flame retardant for flame-retardant polyurethane foam so that the occurrence of can be reduced, and an eco-friendly flame-retardant polyurethane foam manufactured thereby.

일반적으로 폴리우레탄(Polyurethane)이라 함은, 고분자 화합물로서, 알코올기와 아이소사이안산기의 결합으로 이루어지는 것이다.In general, polyurethane (Polyurethane) is a high molecular compound, consisting of a bond between an alcohol group and an isocyanate group.

이러한, 폴리우레탄은 발포한 것을 폴리우레탄 폼(Foam)이라 하며, 경량성 및 경제성 등이 우수하여 단열재로 널리 이용된다.Such polyurethane foam is called polyurethane foam, and is widely used as a heat insulator because of its excellent lightness and economy.

이와 같은, 폴리우레탄 폼은 열에 약한 가연성 물질임과 동시에 연소되는 과정에서 인체에 치명적인 유해 가스가 발생되며, 이러한 가스는 사람의 대피 능력 저하를 유발하게 됨으로써 인명 피해 발생 확률을 높이게 되는 문제점이 있었다.As such, polyurethane foam is a combustible material weak to heat, and at the same time, a harmful gas fatal to the human body is generated in the process of combustion, and such a gas causes a decrease in the evacuation ability of a person, thereby increasing the probability of human damage.

이와 관련하여, 한국 등록 특허 제10-1208343호에서는 스티로폼 입자의 표면에 난연 코팅이 이루어질 수 있도록 한 스티로폼 입자용 난연 코팅액 및 그 제조방법이 개시된다.In this regard, Korean Patent Registration No. 10-1208343 discloses a flame-retardant coating solution for styrofoam particles and a method for manufacturing the same, so that a flame-retardant coating can be made on the surface of the styrofoam particles.

그러나, 이러한 종래의 기술에 따른 스티로폼 입자용 난연 코팅액 및 그 제조방법은, 난연성을 가질 수 있도록 하면서도 유독 가스의 발생량이 저감될 수 있도록 하나 그 효과가 미미한 단점이 있었다.However, the flame-retardant coating solution for styrofoam particles and a method for manufacturing the same according to the prior art have a disadvantage in that the effect is insignificant, although the amount of toxic gas can be reduced while being able to have flame retardancy.

또한, 종래의 LbL 증착은 다수회 반복해야하는 바, 공정 소요 시간이 길어지는 문제점이 있었다.In addition, since the conventional LbL deposition has to be repeated a number of times, there is a problem in that the process takes a long time.

상기 제1 코팅 단계(S20)는, 폴리우레탄 폼을 Poly-D-Lysine 용액, Chitosan 용액, Alginate-Montmorillonite Clay 용액에 순차적으로 침지하는 것으로, 폴리우레탄 폼에 난연성을 부여하기 위한 것이다.In the first coating step (S20), the polyurethane foam is sequentially immersed in a Poly-D-Lysine solution, a Chitosan solution, and an Alginate-Montmorillonite Clay solution, in order to impart flame retardancy to the polyurethane foam.

먼저, 폴리우레탄 폼은 Poly-D-Lysine 용액에 침지된다.First, polyurethane foam is immersed in Poly-D-Lysine solution.

상기 Poly-D-Lysine 용액은, 0.02 ~ 0.03wt%이 포함된 Poly-D-Lysine 수용액이며, 0.025wt%의 Poly-D-Lysine이 포함된 수용액을 최적으로 한다.The Poly-D-Lysine solution is an aqueous solution of Poly-D-Lysine containing 0.02 to 0.03 wt%, and an aqueous solution containing 0.025 wt% of Poly-D-Lysine is optimal.

이러한, Poly-D-Lysine 용액은 양전하를 띠게 된다.This, Poly-D-Lysine solution takes on a positive charge.

더불어, 상기 제1 코팅 단계(S20)에서 폴리우레탄 폼은, Poly-D-Lyine 용액에 100 ~ 140초 동안 침지됨이 바람직하며, 120초 동안 침지되는 것을 최적으로 한다.In addition, the polyurethane foam in the first coating step (S20) is preferably immersed in the Poly-D-Lyine solution for 100 to 140 seconds, and it is optimal to be immersed for 120 seconds.

그리고, Poly-D-Lysine 용액에 침지된 폴리우레탄 폼을 증류수에 세척한 다음 증류수를 짜낼 수 있도록 한다.Then, after washing the polyurethane foam immersed in the Poly-D-Lysine solution in distilled water, the distilled water can be squeezed out.

다음으로, Poly-D-Lysine 용액에 침지된 폴리우레탄 폼은 Chitosan 용액에 침지된다.Next, the polyurethane foam dipped in Poly-D-Lysine solution is dipped in Chitosan solution.

상기 Chitosan 용액은, 0.2 ~ 0.3wt% Chitosan이 포함된 수용액이며, 0.25wt%의 Chitosan이 포함된 수용액을 최적으로 한다.The Chitosan solution is an aqueous solution containing 0.2 to 0.3 wt% Chitosan, and an aqueous solution containing 0.25 wt% Chitosan is optimal.

이러한, Chitosan 용액은 양전하를 띠게 된다.This Chitosan solution is positively charged.

더불어, 상기 제1 코팅 단계(S20)에서 폴리우레탄 폼은, Chitosan 용액에 50 ~ 70초 동안 침지됨이 바람직하며, 60초 동안 침지되는 것을 최적으로 한다.In addition, the polyurethane foam in the first coating step (S20) is preferably immersed in Chitosan solution for 50 to 70 seconds, and it is optimal to be immersed for 60 seconds.

그리고, Chitosan 용액에 침지된 폴리우레탄 폼을 증류수에 세척한 다음 증류수를 짜낼 수 있도록 한다.Then, after washing the polyurethane foam immersed in Chitosan solution in distilled water, the distilled water can be squeezed out.

다음으로, Poly-D-Lysine 용액과 Chitosan 용액에 순차적으로 침지된 폴리우레탄 폼은 Alginate-Montmorillonite Clay 용액에 침지된다.Next, the polyurethane foam immersed in Poly-D-Lysine solution and Chitosan solution sequentially is immersed in Alginate-Montmorillonite Clay solution.

상기 Alginate-Montmorillonite Clay 용액은, 0.25 ~ 0.35wt% Alginate와 0.5 ~ 0.7wt% Montmorillonite Clay이 포함된 수용액이며, 0.3wt%의 Alginate와 0.6wt%의 Montmorillonite Clay가 포함된 수용액을 최적으로 한다.The Alginate-Montmorillonite Clay solution is an aqueous solution containing 0.25 to 0.35wt% Alginate and 0.5 to 0.7wt% Montmorillonite Clay, and an aqueous solution containing 0.3wt% Alginate and 0.6wt% Montmorillonite Clay is optimal.

이러한, Alginate-Montmorillonite Clay 용액은 음전하를 띠게 된다.This, Alginate-Montmorillonite Clay solution is negatively charged.

그리고, Alginate-Montmorillonite Clay 용액에 침지된 폴리우레탄 폼을 증류수에 세척한 다음 증류수를 짜낼 수 있도록 한다.Then, the polyurethane foam immersed in the Alginate-Montmorillonite Clay solution is washed in distilled water and then distilled water can be squeezed out.

이와 같이, Alginate-Montmorillonite Clay 용액이 음전하를 띠게 되므로, 폴리우레탄 폼을 다시 양전하를 띠는 Poly-D-Lysine 용액에 침지할 경우 폴리우레탄 폼의 표면에 보다 잘 밀착되게 되는 것이다.As such, since the Alginate-Montmorillonite Clay solution has a negative charge, when the polyurethane foam is immersed in a Poly-D-Lysine solution having a positive charge again, it will be better adhered to the surface of the polyurethane foam.

더불어, 상기 제1 코팅 단계(S20)에서 폴리우레탄 폼은, Alginate-Montmorillonite Clay 용액에 50 ~ 70초 동안 침지됨이 바람직하며, 60초 동안 침지되는 것을 최적으로 한다.In addition, in the first coating step (S20), the polyurethane foam is preferably immersed in the Alginate-Montmorillonite Clay solution for 50 to 70 seconds, and it is optimal to be immersed for 60 seconds.

그리고, Alginate-Montmorillonite Clay 용액에 침지된 폴리우레탄 폼을 증류수에 세척한 다음 증류수를 짜낼 수 있도록 한다.Then, the polyurethane foam immersed in the Alginate-Montmorillonite Clay solution is washed in distilled water and then distilled water can be squeezed out.

이처럼, Poly-D-Lysine 용액과 Chitosan 용액과 Alginate-Montmorillonite Clay 용액에 순차적으로 침지됨으로써 제1 코팅 단계(S20)가 이루어진 폴리우레탄 폼은, 추가로 제1 코팅 단계(S20)를 다수회 반복하여 수행될 수 있을 것이다.As such, the polyurethane foam having the first coating step (S20) by being sequentially immersed in the Poly-D-Lysine solution, the Chitosan solution, and the Alginate-Montmorillonite Clay solution is additionally the first coating step (S20) by repeating a plurality of times. it could be done
