Description
본 발명은 폐스티로폼을 이용한 난연보드의 제조방법에 관한 것으로서, 더욱 상세하게는 폐기되는 스티로품을 재활용함으로써 자원의 낭비와 환경오염을 방지 함과 동시에 불에 잘 타지 않아 화재가 확산되지 않도록 하는 폐스티로폼을 이용한 난연보드의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a flame retardant board using waste styrofoam. More specifically, waste styrofoam prevents waste of resources and environmental pollution by recycling discarded styrofoam and at the same time prevents fire from spreading by being resistant to fire. It relates to a method of manufacturing a flame retardant board using .
일반적으로 스티로폼은, 내수성과 단열성은 물론 방음성과 완충성 등이 매우 우수하고 가벼우며 가격이 저렴하기 때문에 냉동창고나 물류창고 또는 공장들의 벽이나 지붕 등을 조립식으로 시공하는 건축자재인 샌드위치패널에도 널리 사용되고 있다.In general, Styrofoam has excellent water resistance and heat insulation as well as soundproofing and cushioning properties, is light, and is inexpensive, so it is widely used in sandwich panels, a construction material used to prefabricate walls and roofs of refrigerated warehouses, distribution warehouses, or factories. It is being used.
그런데, 이러한 샌드위치패널은 스티로폼으로 되는 심재의 양면에 알루미늄판이나 스테인리스판 등의 강도가 큰 재료로 되는 표면재를 접착하여 제작되는 것이므로, 종래에는 화재가 발생하면 심재인 스티로폼이 패널의 내부에서 매우 빠르게 연소하게 됨은 물론 화재가 빠르게 확산되며, 스티로폼이 연소되는 위치와 정도 등을 신속하게 파악할 수 없기 때문에 초기 진압이 어렵고 소화약제나 소화용수가 표면재에 의해 내부로 쉽게 투입되지 않아 화재가 걷잡을 수 없이 확산되어 대형화재로 됨은 물론 스티로폼의 연소시 발생하는 다량의 유독가스 등에 의해 화재진압을 더욱 어렵게 함과 동시에 막대한 인명 및 재산의 피해가 초래되는 등의 문제점들이 있었다.However, since these sandwich panels are manufactured by adhering surface materials made of high-strength materials such as aluminum plates or stainless steel plates to both sides of a core made of Styrofoam, conventionally, when a fire occurs, the Styrofoam core material burns very quickly inside the panel. In addition, the fire spreads quickly, and because it is not possible to quickly determine the location and extent of Styrofoam combustion, initial suppression is difficult, and because fire extinguishing agents or water are not easily injected inside due to the surface material, the fire spreads uncontrollably. Not only did it become a large-scale fire, but it also made fire suppression more difficult due to the large amount of toxic gases generated when Styrofoam was burned, and at the same time, there were problems such as causing enormous damage to life and property.
또한, 스티로폼은 샌드위치패널외에도 1회용의 컵이나 그릇·접시·용기 또는 각종 농축수산물의 포장용기 및 전자제품이나 기타 부서지기 쉬운 물품의 운송용 포장재 등과 같이 그 사용범위가 매우 넓어 폐스티로폼이 방대한 양으로 배출되는데, 그대로 매립하면 썩거나 분해되지 않고 소각하면 유해 가스와 매연이 배출되어 자연환경을 오염시키게 됨은 물론 폐기처리하는 과정 처리비용이 많이 소요되기 때문에 막대한 자원과 비용의 낭비가 초래되는 등의 문제점 들도 있었다.In addition, in addition to sandwich panels, Styrofoam has a very wide range of uses, such as disposable cups, bowls, plates, containers, packaging containers for various agricultural, livestock and marine products, and packaging materials for transporting electronic products and other fragile items, so waste Styrofoam is used in vast quantities. However, if it is buried as is, it will not rot or decompose, and if it is incinerated, harmful gases and smoke will be emitted, polluting the natural environment, and the disposal process will cost a lot of money, resulting in a huge waste of resources and money. There were also
본 발명은 종래의 이러한 점들을 감안하여 발명된 것으로서, 그 목적은 폐기되는 스티로품을 수거하여 불에 잘 타지 않게 되는 난연보드로 만들어 샌드위치패널 등의 각종 건축자재들 외에도 다양한 용도에 유용하게 적용할 수 있도록 하는 폐스티로폼을 이용한 난연보드의 제조방법을 제공하는 것이다.The present invention was invented in consideration of these points in the past, and its purpose is to collect discarded Styro products and make them into fire-retardant boards that do not burn easily, so that they can be usefully applied to various uses in addition to various construction materials such as sandwich panels. To provide a method of manufacturing a flame retardant board using waste Styrofoam.

이와 같은 본 발명에 따른 폐스티로폼을 이용한 난연보드의 제조방법에 의해 제조되는 난연보드는, 폐기되는 스티로품을 재활용하는 것이므로 막대한 자원과 비용의 낭비 및 환경오염을 방지하게 되는 등의 효과를 얻게 되는 것임은 물론 내충격성과 내마모성 및 단열성이 매우 우수하여 샌드위치패널외에도 실내의 결로방지용 단열재로 사용하는 등 다양한 용도에 적용할 수 있게 되는 특징도 있다.Since the flame retardant board manufactured by the method of manufacturing a flame retardant board using waste Styrofoam according to the present invention recycles discarded Styrofoam, it achieves the effect of preventing waste of enormous resources and costs and environmental pollution.

이하, 본 발명에 따른 폐스티로폼을 이용한 난연보드의 제조방법을 첨부된 도면에 의거하여 상세하게 설명하면 다음과 같다.Hereinafter, the method of manufacturing a flame retardant board using waste Styrofoam according to the present invention will be described in detail based on the attached drawings.
도 1은 본 발명에 따른 폐스티로폼을 이용한 난연보드의 제조방법을 보인 공정도이다.Figure 1 is a process diagram showing a method of manufacturing a flame retardant board using waste Styrofoam according to the present invention.
도 1의 본 발명에 따른 폐스티로폼을 이용한 난연보드의 제조방법은, 폐스티로폼을 세척한 후 건조하는 제1공정(10)과, 상기 건조된 폐스티로폼을 소정 크기의 입자로 되게 분쇄하는 제2공정(20)과, 상기 폐스티로폼 입자에 혼합물인 난연제 및 젤라틴을 먼저 투입하고 1차로 교반하여 혼합한 다음 다른 혼합물인 액상의 접착성이 우수한 생분해성 수지를 투입하고 2차로 교반하여 겔 상태의 난연혼합물을 얻는 제3공정(30)과, 상기 겔 상태의 난연혼합물을 저온으로 숙성하는 제4공정(30)과, 상기 저온숙성된 겔 상태의 난연혼합물을 원하는 크기의 금형에 주입하고 열압착하여 난연보드를 성형하는 제5공정(50) 및 상기 성형된 난연보드를 금형에서 인출한 다음 외면에 생분해성수지를 도포한 다음 건조하는 제6공정(50)을 포함하여 이루어지는 것을 특징으로 한다.The method of manufacturing a flame retardant board using waste Styrofoam according to the present invention in Figure 1 includes a first step (10) of washing and drying the waste Styrofoam, and a second step of pulverizing the dried waste Styrofoam into particles of a predetermined size. In process (20), a mixture of flame retardant and gelatin is first added to the waste Styrofoam particles, first stirred and mixed, and then another mixture, a liquid biodegradable resin with excellent adhesiveness, is added and secondarily stirred to form a gel-like flame retardant. A third process (30) of obtaining the mixture, a fourth process (30) of maturing the gel-like flame retardant mixture at a low temperature, and injecting the low-temperature-aged gel-like flame retardant mixture into a mold of a desired size and heat-pressing it. It is characterized by comprising a fifth process (50) of molding the flame retardant board and a sixth process (50) of removing the molded flame retardant board from the mold, applying biodegradable resin to the outer surface, and then drying it.
제1공정(10)은, 수거된 재활용이 가능한 폐스티로폼을 세척하여 폐스티로폼에 묻어 있는 불순물이나 이물질 등을 깨끗하게 제거한 다음 건조하는 공정이다.The first process (10) is a process of washing the collected recyclable waste Styrofoam to cleanly remove impurities or foreign substances on the waste Styrofoam and then drying it.
이렇게 폐스티로폼을 세척하는 것은, 오염되지 않은 새로운 스티로폼을 사용하여 난연보드를 제조하는 것과 동일하게 되도록 하기 위한 것이다.Washing waste Styrofoam in this way is intended to be the same as manufacturing a flame retardant board using new, uncontaminated Styrofoam.
그리고 세척이 왼료된 폐스티로폼의 건조는, 자연 건조 또는 필요에 따라 건조실에서 단시간에 대량으로 건조하여도 된다.Additionally, the cleaned waste Styrofoam can be dried naturally or, if necessary, in a large quantity in a short period of time in a drying room.
제2공정(20)은, 세척 및 건조가 왼료된 폐스티로폼을 분쇄기에 넣어 소정 크기의 입자로 되게 분쇄하는 공정이다.The second process (20) is a process in which the washed and dried waste Styrofoam is placed in a grinder and pulverized into particles of a predetermined size.
이때, 분쇄되는 폐스티로폼 입자의 크기는 3~5㎜로 되게 하는 것이 바랍직한데, 이는 제3공정에서 분쇄된 폐스티로폼 입자를 난연혼합물에 투입하고 교반하여 혼합할 때 입자의 크기가 3㎜보다 작은 경우에는 각 입자에 난연혼합물의 성분들이 모두 혼입되지 않게 되는 현상이 일부 발생하고, 5㎜보다 큰 경우에는 각 입자에 혼입되는 난연혼합물의 각 상분들 분량이 서로 다르게 되는 현상이 일부 발생하는 반면에, 3~5㎜ 정도의 크기에서는 비교적 난연제들이 고르게 혼입되기 때문이다.At this time, it is desirable that the size of the pulverized waste Styrofoam particles be 3 to 5 mm. This means that when the pulverized waste Styrofoam particles in the third process are added to the flame retardant mixture and stirred to mix, the particle size should be larger than 3 mm. In the case of small particles, some phenomena occur in which all the components of the flame retardant mixture are not mixed into each particle, while in the case of larger than 5 mm, some phenomena occur in which the amounts of each phase of the flame retardant mixture mixed in each particle are different from each other. This is because flame retardants are mixed relatively evenly at a size of about 3 to 5 mm.
제3공정(30)은, 폐스티로폼 입자에 혼합물인 난연제 및 젤라틴을 투입하여 1차로 교반하여 혼합한 다음 다른 혼합물인 접착성이 우수한 액상의 생분해성 수지를 투입하고 2차로 교반하여 겔 상태의 난연혼합물 얻는 공정이다.In the third process (30), a mixture of flame retardant and gelatin is added to waste Styrofoam particles, first stirred and mixed, then another mixture, a liquid biodegradable resin with excellent adhesiveness, is added and secondarily stirred to form a gel-like flame retardant. This is the process of obtaining a mixture.
1차 교반할 때에는, 폐스티로폼 입자 100중량부에 난연제로 포말소화 약제인 탄산수소나트륨(NaHCO₃) 5~10중량부와, 염화나트륨(NaCl) 1~5중량부 및 이산화규소(SiO₂) 1~5중량부와, 포 안정제로 젤라틴 20~30중량부를 투입하여 혼합한다.During the first stirring, 5 to 10 parts by weight of sodium bicarbonate (NaHCO₃), a foam extinguishing agent as a flame retardant, 1 to 5 parts by weight of sodium chloride (NaCl), and 1 to 5 parts by weight of silicon dioxide (SiO₂) are added to 100 parts by weight of waste Styrofoam particles. Add 20 to 30 parts by weight of gelatin as a foam stabilizer and mix.
2차 교반할 때에는, 1차 혼합물의 중량부에 대해 액상의 생분해성 수지 150~200중량부를 투입하여 혼합한다.During secondary stirring, 150 to 200 parts by weight of liquid biodegradable resin is added and mixed relative to the weight of the first mixture.
제4공정(40)은, 제3공정에서 얻은 겔 상태의 난연혼합물을 10~15℃의 저온에서 5~10시간 숙성하는 공정이다.The fourth process 40 is a process of maturing the gel-like flame retardant mixture obtained in the third process at a low temperature of 10 to 15 ° C. for 5 to 10 hours.
이와 같이 겔 상태의 난연혼합물을 저온에서 숙성하면, 난연제와 포 안정제가 생분해성 수지에 의해 폐스티로폼 입자들에 고르게 혼입된다.When the gel-like flame retardant mixture is aged at low temperature, the flame retardant and foam stabilizer are evenly incorporated into the waste Styrofoam particles by the biodegradable resin.
제5공정(50)은, 저온숙성된 겔 상태의 난연혼합물을 100~120℃로 가열되는 금형에 주입하고 20~30초 동안 열압착성형하여 난연보드를 얻는 공정이다.The fifth process 50 is a process of obtaining a flame retardant board by injecting a low-temperature-aged gel-like flame retardant mixture into a mold heated to 100 to 120°C and thermocompression molding for 20 to 30 seconds.
이렇게 얻게 되는 난연보드는, 난연제와 포 안정제가 고르게 혼입되어 있는 폐스티로폼 입자들이 생분해성 수지에 의해 접착되기 때문에 취급시 일반적인 스티로폼과는 달리 충격 등에 의해 쉽게 파손되지 않게 됨은 물론 투습 및 흡습작용이없어 단열성이 매우 우수하고 실내의 결로방지용 단열재로도 유용하게 사용되는 등의 장점이 있다.The flame retardant board obtained in this way is made up of waste Styrofoam particles mixed with flame retardants and foam stabilizers evenly mixed together and bonded by biodegradable resin, so unlike general Styrofoam, it is not easily damaged by impact, etc. when handled, and has no moisture permeability or moisture absorption effect. It has excellent insulation properties and has the advantage of being useful as an indoor insulating material to prevent condensation.
또한, 난연보드는 금형의 사이즈와 압착하는 정도에 비례하여 원하는 크기와 두께로 성형할 수 있게 된다.Additionally, the flame retardant board can be molded to a desired size and thickness in proportion to the size of the mold and the degree of compression.
제6공정(60)은, 금형에서 인출한 난연보드의 표면에 생분해성 수지를 대략 0,1~0,3㎜로 도포하는 공정이다.The sixth process 60 is a process of applying biodegradable resin to a thickness of approximately 0,1 to 0,3 mm on the surface of the flame retardant board taken out of the mold.
이렇게 표면에 생분해성 수지를 도포하면, 난연보드의 내충격성과 내마모성을 더욱 향성시켜 줌은 물론 샌드위치패널을 제작할 때 양면에 표면재가 매우 용이하게 접착됨과 동시에 장기간이 경과하여도 쉽게 박리되지 않게 되어 수명단축이 방지되는 등의 장점도 있다.Applying biodegradable resin to the surface in this way not only improves the impact resistance and abrasion resistance of the flame retardant board, but also makes it very easy for the surface material to adhere to both sides when manufacturing a sandwich panel, and at the same time, it does not easily peel off even after a long period of time, shortening the lifespan. There are also advantages such as preventing this.
이와 같이 본 발명에 따른 폐스티로폼을 이용한 난연보드의 제조방법에 의해 얻게 되는 난연보드는, 수거된 폐스티로폼을 이용하여 난연보드를 제조함으로써 폐기되는 스티로품을 재활용할 수 있게 되고, 제조되는 난연보드의 단열성 및 기계적인 물성이 강화되며, 폐스티로폼의 소각 또는 폐기에 따른 환경오염 등의 문제를 해결할 수 있게 된다.In this way, the flame retardant board obtained by the method of manufacturing a flame retardant board using waste Styrofoam according to the present invention can recycle discarded Styro products by manufacturing a flame retardant board using collected waste Styrofoam, and the flame retardant board manufactured Insulation and mechanical properties are strengthened, and problems such as environmental pollution caused by incineration or disposal of waste Styrofoam can be solved.
