본 발명은 난연성 발포스티로폼 제조용 난연비드 조성물 및 이를 이용한 난연비드의 제조방법에 관한 것으로서 보다 구체적으로는 발포되는 스티로폼제조입자인 노비드에 혼합하여 예비발포함으로써 제조되는 비드의 내부에 자기소화성을 갖는 난연화 조성물이 투입되게 함으로서 이를 원료로 하여 제조되는 발포스티로폼이 자기소화성을 갖도록 하여 난연3등급의 난연성 발포스티로폼을 제조할 수 있도록 한 것이다.The present invention relates to a flame retardant bead composition for producing a flame retardant foamed styrofoam and a method for producing a flame retardant bead using the same. More specifically, a flame retardant having self-extinguishing property in a bead prepared by mixing with a pre-foamed foamed styrofoam manufacturing particle. By allowing the composition to be injected, the foamed styrofoam prepared as a raw material has a self-extinguishing ability to prepare a flame-retardant grade 3 flame-retardant foamed styrofoam.

일반적으로 발포스티로폼(Expandable Polystyrene)은 단열성과 완충성 및 가공성이 우수하므로 산업 전반에 걸쳐 널리 사용되고 있으며 특히 제품을 보호하는 포장재나 건축용 단열재 및 흡음재로서 주로 사용되고 있다.In general, expandable polystyrene is widely used throughout the industry because of its excellent thermal insulation, buffering properties, and processability, and is mainly used as a packaging material for protecting products, insulation for building, and sound absorption material.

하지만 상기 스티로폼은 열에 매우 취약하므로 화재시 열에 의해 스티로폼이 연소되어 화재의 확산을 초래하고 인체에 유해한 유독가스를 발생 시킴으로서 인명피해를 유발시키는 문제점이 있었다.However, since the styrofoam is very vulnerable to heat, the styrofoam is burned by heat during fire, causing the spread of fire and generating toxic gases harmful to the human body.

따라서 근래에는 상기와 같은 종래의 결점을 해소하고자 난연성을 갖는 발포스티로폼에 관한 연구가 활발히 진행되고 있으며 그 일 예로 성형스티로폼의 원료인 비드에 다공성 광물입자를 혼합하여 압축 성형한 것 및 성형된 스티로폼의 외측에 난연성시트 또는 난연제를 도포한 것과 완성된 발포스티로폼으로 내측으로 난연재를 주사하여 난연효과를 나타내도록 한 것 등이 있으나 종래 비드의 외측에 다공성 광물입자를 도포하여 스티로폼을 압축 성형한 것은 난연성은 우수하나 스티로폼의 우수한 성질인 가공성과 단열성 및 성형성을 감소시키게 되고 제조된 스티로폼이 무겁고 쉽게 부러지는 성질이 있어 취급이 어려울 뿐만 아니라, 생산성이 떨어지게 되고 완성된 제품에 수분이 침투하면 난연제의 융착성이 떨어지는 등의 결점이 있고 스티로폼의 외측에 난연성시트 또는 난연재를 도포한 것은 난연재를 스티로폼의 표면에 도포하고 건조하여야 하므로 작업에 많은 인력과 시간이 소요되어 생산성이 저하되고 대형의 제조장치가 추가되어 제조되는 스티로폼의 가격이 상승하게 되며 스티로폼의 내부 및 절단면에는 난연재가 존재하지 않음으로써 화재가 어느 정도 진척되면 내부의 스티로폼이 연소되는 문제점이 있으며 성형된 발포스티로폼의 내측으로 난연재를 투입하는 것은 성형된 스티로폼에 다수의 주사바늘을 이용하여 난연재를 스티로폼의 내측으로 주사하는 것으로 이는 시간이 지남에 따라 스티로폼의 내부에 주사된 난연재가 주사바늘에 의해 형성되는 구멍을 통하여 외부로 흘러나오게 되어 난연효과가 떨어지게 되고 스티로폼의 표면에 수많은 주사바늘구멍이 형성됨으로써 스티로폼의 강도가 저하되는 등의 결점이 있었다.Therefore, in recent years, active researches on foamed styrofoam having flame retardancy to solve the above-mentioned drawbacks have been actively conducted. For example, compression molding and mixing of porous mineral particles into beads, which are raw materials of molded styrofoam, and molded styrofoam The application of a flame retardant sheet or flame retardant to the outside and the injection of the flame retardant material into the foamed styrofoam to show the flame retardant effect, but compression molding of the styrofoam by applying porous mineral particles to the outside of the conventional beads. Although excellent in styrofoam, processability, insulation and moldability are reduced, and the produced styrofoam has a heavy and easily broken property, making it difficult to handle and reducing productivity and fusion of flame retardant when moisture penetrates the finished product. It has flaws like falling and styro The application of the flame retardant sheet or flame retardant on the outside of the styrofoam to apply the flame retardant to the surface of the styrofoam and dry it takes a lot of manpower and time to work, the productivity is lowered and the price of the styrofoam manufactured by the addition of a large manufacturing apparatus is increased Since there is no flame retardant material on the inside and the cut surface of the styrofoam, there is a problem that the styrofoam inside is burned when the fire progresses to a certain extent.Injecting the flame retardant into the molded foam styrofoam uses a plurality of needles in the molded styrofoam. The flame retardant is injected into the styrofoam. This means that the flame retardant injected into the styrofoam flows out through the hole formed by the needle as time goes by, and the flame retardant effect is reduced. As the hole is formed There were drawbacks, such as the strength of the tee form to be lowered.

본 발명은 상기와 같은 종래와 같은 문제점을 해결하고자 제안한 것으로서 스티로폼의 성형원료가 되는 비드의 내측으로 자기소화성을 갖는 난연재를 투입되도록 하여 스티로폼의 우수한 특성을 저해하지 않으면서 자기소화성을 갖도록 하여 화염이 전달되거나 유해가스가 발생하지 않도록 하는 발포스티로폼의 제조용 조성물을 제안함과 동시에 이를 이용하여 난연3등급의 발포스티로폼의 제조방법을 제안함에 그 목적이 있다.The present invention has been proposed to solve the problems as described above as a flame retardant by having a self-extinguishing material without impairing the excellent properties of the styrofoam by introducing a flame retardant having a self-extinguishing material into the bead to be a molding material of the styrofoam.

즉 본 발명은 3차 혼합물이 본원발명의 난연비드 조성물이며 이를 예비발포함으로써 내측으로 난연재가 투입된 스티로폼의 1차가공 원료인 난연비드를 얻을 수 있으며 이를 압축성형공정을 거쳐 완성된 발포스티로폼을 얻게 되는 것이다.That is, in the present invention, the third mixture is a flame retardant bead composition of the present invention, and by pre-expanding it, a flame retardant bead, which is a primary processing material of styrofoam into which a flame retardant is injected, can be obtained, and a foamed styrofoam obtained through a compression molding process is obtained. will be.

도 2는 본 발명의 제조공정에 의해 제조되는 난연비드의 제조실시예를 나타낸 예시도로서 상기 공정에 의하여 발포스티로폼의 원료인 비드의 내측으로 난연제가 투입되는 예시도가 도시되어 있다. Figure 2 is an exemplary view showing a manufacturing example of a flame retardant bead produced by the manufacturing process of the present invention is an exemplary diagram in which a flame retardant is injected into the bead of the raw material of the foamed styrofoam by the above process.

즉 본 발명은 원료인 노비드에 1차혼합물(P1)과 액상유리를 혼합하는 2차배합공정((S2)을 거치면 노비드의 표면에 1차혼합물(P1) 및 2차 혼합약품인 액상유리가 불규칙하게 노비드의 표면에 붙어서 혼합되는 2차 혼합물(P2)을 얻을 수 있으며 이를 3차혼합약품인 인산암모늄과 계면활성제를 혼합하는 3차배합공정(S3)을 거치면 노비드의 표면에 부착된 1차와 2차 혼합물(P1)(P2)에 인산암모늄과 계면활성제가 안정화되어 균일하게 코팅된 형태의 3차혼합물(P3)을 얻게 되며 이를 예비발포공정을 통하여 발포하게 되면 노비드가 팽창하여 발포됨과 동시에 표면층에 코팅된 1,2,3차 혼합물(P3)이 노비드의 팽창력에 의해 내측으로 투입되는 발포가스와 함께 발포된 결과물 즉 비드의 내측에 투입되어 위치하게 되고 시간이 지남에 따라 발포가스는 배출됨으로써 비드의 내측에는 난연재인 혼합약품과 소량의 발포가스만이 존재하게 되므로 발포스티로폼의 원료인 비드를 얻을 수 있게 되는 것이다. That is, according to the present invention, when the first mixture (P1) and the liquid glass are mixed with the first material (P1) and the liquid glass as the raw material, the first glass (P1) and the second liquid mixture glass are irregular on the surface of the bead.
