Description
본 발명은 내부에 탄소 및 질소가스를 충진하고 표면에 무기계난연재를 도포하여 난연성을 부여한 발포폴리스틸렌입자의 발포소재인 난연비드조성물 및 난연비드 조성물의 제조방법에 관한 것이다.The present invention relates to a flame-retardant bead composition and a method for producing a flame-retardant bead composition, which is a foaming material of expanded polystyrene particles, which is filled with carbon and nitrogen gas and imparted with flame retardancy by applying an inorganic flame-retardant material to the surface.
발포폴리스티렌(Expandable Polystyrene)은 단열성과 완충성 및 가공성이 우수하므로 산업 전반에 걸쳐 널리사용되고 있으며, 특히 건축용 단열재와 흡음재 및 외부의 충격으로 부터 제품을 보호하는 포장재 등으로 널리 사용되고 있지만 열과 화기에 매우 취약한 특성으로 인해 화재시 그 화력의 확산 매개로 작용하여 대형화재를 일으키는 원인을 제공할 뿐만 아니라, 연소되는 과정에서 인체에 치명적인 유독가스가 발생되어 큰 인명피해를 유발하기도 하는 등 상당한 단점도 가지고 있기 때문에 근래에는 발포폴리스티렌에 난연성을 부여하기 위한 연구·노력이 활발히 진행되고 있으며 일예로 발포폴리스티렌의 원료인 비드에 다공성 광물입자를 단순히 도포한 후 이를 이용해 발포 및 압축 성형을 통해 제조하는 방법(특허 제10-0492199호, 제10-0782311호)Expandable polystyrene is widely used throughout the industry because of its excellent insulation, buffering properties and processability. Due to its characteristics, in case of fire, it acts as a diffusion medium of the thermal power and provides a cause of causing a large fire. Recently, research and efforts to impart flame retardancy to expanded polystyrene are being actively conducted. For example, a method of manufacturing through foaming and compression molding using porous mineral particles by simply applying porous mineral particles to beads, which are raw materials of expanded polystyrene (Patent No. 10). -0492199, 10-0782311)
발포, 압축성형된 발포폴리스티렌의 외면에 별도 제작된 난연성시트 내지 난연제를 추가 도포하여 난연성이 발휘되도록 하는 방법과 완성된 발포폴리스티렌성형물에 주사 바늘로 난연재를 주사하여 난연기능을 갖도록 하는 방법 등이 있다. There is a method of additionally applying a flame retardant sheet or a flame retardant prepared separately to the outer surface of foamed or compression-molded expanded polystyrene to exhibit flame retardancy, and a method of injecting a flame retardant into the finished expanded polystyrene molded product with a needle to have a flame retardant function. .
상기한 종래방법 중 비드의 외측에 다공성 광물입자를 도포하여 발포폴리스티렌을 압축 성형하는 방법은 난연성은 우수하나 발포폴리스티렌의 고유한 성질인 가공성과 단열성 및 성형성을 감소시키게 되고 제조된 발포폴리스티렌이 무겁고 쉽게 부러지는 성질이 있어, 취급이 어려울 뿐만 아니라 생산성이 떨어지게 되고 완성된 제품에 수분이 침투하면 난연제의 융착성이 떨어지는 등의 결점이 있고, 발포폴리스티렌의 외면에 난연성시트 또는 난연재를 도포하는 방법의 경우는 난연재를 발포폴리스티렌의 성형물표면에 도포하고 건조하여야 하므로 작업에 많은 인력과 시간이 소요되어 생산성이 저하되고 대형의 제조장치가 추가되어 제조되는 발포폴리스티렌의 가격이 상승하게 되며 발포폴리스티렌의 내부 및 절단면에는 난연재가 존재하지 않음으로써 화재가 어느정도 진척되면 내부의 발포폴리스티렌이 연소되는 문제점이 있으며,성형된 발포폴리스티렌의 내측으로 난연재를 주사하여 투입하는 것은 성형된 발포폴리스티렌에 다수의 주사바늘 구멍등 외면이 손상되어 발포폴리스티렌 성형물의 강도를 약화할 뿐만 아니라, 그 수많은 바늘구멍을 통해 내부 함침된 난연재가 외부로 유출되어 난연효과가 떨어지게 되는 문제점이 있었다.Among the above conventional methods, the method of compression molding expanded polystyrene by applying porous mineral particles to the outside of the beads has excellent flame retardancy, but reduces processability, thermal insulation and moldability, which are inherent properties of expanded polystyrene, and the manufactured expanded polystyrene is heavy and It has a property of being easily brittle, so it is difficult to handle, and productivity is lowered, and when moisture penetrates into the finished product, there are drawbacks such as poor adhesion of the flame retardant. In this case, the flame retardant material must be applied to the surface of the expanded polystyrene molded product and dried, so it takes a lot of manpower and time to work, lowering productivity, adding a large manufacturing device, and increasing the price of expanded polystyrene. Since there is no flame retardant on the cut surface, there is a problem that the internal expanded polystyrene is burned when the fire progresses to some extent. This damage not only weakens the strength of the expanded polystyrene molding, but also has a problem in that the flame retardant material impregnated inside is leaked out through the numerous needle holes, thereby reducing the flame retardant effect.
본 발명은 상기와 같은 종래와 같은 문제점을 해결하고자 제안한 것으로서 스티로폼의 성형원료가 되는 비드의 내측으로 자기소화성을 갖는 난연재를 투입되도록 하여 발포폴리스티렌의 우수한 특성을 저해하지 않으면서 자기소화성을 갖도록 하여 화염이 전달되거나 유해가스가 발생하지 않도록 하는 난연비드조성물 및 난연발포폴리스티렌의 원료가 되는 난연비드조성물의 제조방법을 제안함에 그 목적이 있다.The present invention has been proposed to solve the same problems as in the prior art, and by injecting a flame retardant having self-extinguishing properties into the inside of a bead, which is a molding raw material of Styrofoam, to have self-extinguishing properties without compromising the excellent properties of expanded polystyrene. An object of the present invention is to propose a flame-retardant bead composition and a method for producing a flame-retardant bead composition which is a raw material of flame-retardant expanded polystyrene to prevent the transmission or harmful gas from being generated.
본 발명에서 난연비드조성물은 점성을 가지는 액상의 제1조성물과 분말형의 제2조성물을 순차로 EPS와 혼합하여 난연비드조성물을 형성하는 것으로 난연비드조성물은 연소하기 쉬운 성질을 가진 비드에 불연성 효과가 큰 물질을 첨가함으로써 발화를 늦춰주고, 연소의 확대를 막아주는 첨가제로 크게 첨가형 난연재와 반응형난연재로 구분할 수 있으며 본 발명은 첨가형 난연제 난연성분의 물질을 비드에 물리적으로 혼합, 첨가, 분산하여 흡열반응 등에 의해서 연소되는 곳의 온도를 떨어뜨리는 냉각 및 열, 가연성기체, 산소등 이동방지을 방지하여 연소반응의 지연하는 보호막의 형성하고 비가연성 물질을 생성하여 가연성분을 희석하여 난연 효과를 얻는 것에 그 특징이 있다.In the present invention, the flame-retardant bead composition is to form a flame-retardant bead composition by sequentially mixing a liquid first composition having viscosity and a powder-type second composition with EPS. It is an additive that slows ignition by adding a large material and prevents the expansion of combustion. It can be largely divided into additive type flame retardant and reactive flame retardant. In order to obtain a flame retardant effect by forming a protective film that delays combustion reaction by preventing cooling and heat, inflammable gas, oxygen, etc., which decrease the temperature of the combustion site by endothermic reaction, etc. It has its characteristics.

인계난연재의 난연 메커니즘은 열분해에 의해 인산 메타인산과 폴리메타 인산을 생성해, 인산 층에 의한 보호 층의 형성과 폴리메타 인산에 의한 탈수작용으로 생성된 열전도율이 낮은 탄화피막을 형성하므로써는 탄화물에 의한 연소를 방지하는 차단 효과가 주로 작용하여 난연성을 나타낸다.The flame retardant mechanism of phosphorus-based flame retardants produces metaphosphoric acid and polymetaphosphoric acid by thermal decomposition, and forms a carbonized film with low thermal conductivity created by the formation of a protective layer by the phosphoric acid layer and dehydration by polymetaphosphoric acid, thereby protecting the carbide. The blocking effect to prevent combustion by the main action acts as a flame retardant.

It is diluted to produce a flame retardant effect.
요소는 본 발명 제1조성물에서 9~11%중량비를 갖는다.Urea has a weight ratio of 9 to 11% in the first composition of the present invention.

When heated, it decomposes into ammonia, water and carbon dioxide, thereby preventing the movement of combustible gases and oxygen, thereby delaying the combustion reaction. It creates a flame retardant effect by diluting combustible components by forming a protective film that
