Abstract
Description
본 발명은 외부 벽체용 단열재 및 그의 제조 방법에 관한 것으로, 좀 더 상세하게는 코팅제에 의해 코팅된 발포 폴리스티렌을 난연성 바인더로 충진하여 제조된 박판 형태의 발포 폴리스티렌층과 열차단성 접착제층이 반복되어 이루어진 외부 벽체용 단열재 및 그의 제조 방법에 관한 것이다.The present invention relates to a heat insulating material for an outer wall and a method of manufacturing the same, and more particularly, to a heat insulating material for an outer wall and a method of manufacturing the same, And a method of manufacturing the same.
일반적으로 발포 스티렌(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.Generally, expandable polystyrene is widely used throughout the industry due to its excellent heat insulating property, buffering property and processability, and is mainly used as a packaging material for protecting a product, a thermal insulating material for buildings, and a sound absorbing material.
그러나, 이러한 스티렌 폼은 열에 매우 취약하므로 화재시 열에 의해 스티렌이 연소되어 화재의 확산을 초래하고 인체에 유해한 유독가스를 발생시킴으로써 인명피해를 유발시키는 문제점이 있었다.However, since such styrene foam is very vulnerable to heat, styrene is burned by heat in the case of fire, resulting in diffusion of fire and poisonous gas harmful to the human body, thereby causing personal injury.
따라서 근래에는 상기와 같은 종래의 결점을 해소하고자 난연성을 갖는 발포스티렌에 관한 연구가 활발히 진행되고 있으며, 그 일 예로 성형 스티렌 폼의 원료인 비드에 다공성 광물입자를 혼합하여 압축 성형한 것 및 성형된 스티렌 폼의 외측에 난연성 시트 또는 난연제를 도포한 것과 완성된 발포 스티렌 폼의 내측으로 난연제를 주사하여 난연 효과를 나타내도록 한 것 등이 있으나, 종래 비드의 외측에 다공성 광물입자를 도포하여 스티렌 폼을 압축 성형한 것은 난연성은 우수하나 스티렌 폼의 우수한 성질인 가공성과 단열성 및 성형성을 감소시키게 되고 제조된 스티렌 폼이 무겁고 쉽게 부러지는 성질이 있어 취급이 어려울 뿐만 아니라, 생산성이 떨어지게 되고 완성된 제품에 수분이 침투하면 난연제의 융착성이 떨어지는 등의 결점이 있고, 스티렌 폼의 외측에 난연성 시트 또는 난연제를 도포한 것은 난연제를 스티렌 폼의 표면에 도포하고 건조하여야 하므로 작업에 많은 인력과 시간이 소요되어 생산성이 저하되고 대형의 제조장치가 추가되어 제조되는 스티렌 폼의 가격이 상승하게 되며 스티렌 폼의 내부 및 절단면에는 난연제가 존재하지 않음으로써 화재가 어느 정도 진척되면 내부의 스티렌 폼이 연소되는 문제점이 있다.In recent years, studies have been made on foamed styrene having flame retardancy to solve the above-mentioned conventional drawbacks. For example, porous microparticles are mixed with beads, which are a raw material of molded styrene foam, There is a method in which a flame retardant sheet or a flame retardant is applied to the outside of the styrene foam and a flame retardant is injected to the inside of the finished foamed styrene foam to exhibit a flame retardant effect. Conventionally, porous mineral particles are applied to the outside of the bead to form styrene foam The compression molded product is excellent in flame retardancy but reduces the processability, heat insulating property and formability, which are excellent properties of the styrene foam, and the produced styrene foam is heavy and easily breakable, which makes handling difficult and lowers the productivity. There is a drawback that when the moisture penetrates, the fusion bonding property of the flame retardant is deteriorated. The flame retardant sheet or the flame retardant is applied to the outside of the Tirene foam because the flame retardant is applied to the surface of the styrene foam and dried, There is no flame retardant in the inside and the cut surface of the styrene foam, so that the styrene foam inside is burned if the fire progresses to some extent.
발포 스티렌 폼의 난연성 부족을 해결하기 위하여 다양한 난연재료를 이용한 방법들이 강구되고 있는바, 그 몇 가지 예를 들어보면 다음과 같다.In order to solve the shortage of flame retardancy of expanded styrene foam, various methods using flame retardant materials have been proposed. Some examples are as follows.
일본특허 JP2001-164031A호에는 내열, 난연성을 가지는 다공성 성형체를 제조하기 위하여 다공성을 갖는 발포수지에 붕소계 무기화합물과 열경화성수지의 혼합물을 피복시키는 방법이 개시되어 있으나, 이는 다공성 발포소지에 내화성 및 소염성, 형태 보존성을 제공한다는 측면에서는 일정한 효과를 제공하고 있지만, 코팅 혼합물의 주성분으로서 붕산과 같은 붕소계 무기 화합물을 사용하고 있고, 또 이외에 글라스섬유, 탄소섬유, 실리카, 탈크와 같은 무기 분체립 등을 사용함으로써 코팅된 발포 입자의 건조과정, 성형과정에서 첨가된 무기 화합물들이 쉽게 이탈되는 문제를 야기하게 되고, 또 인체에 유해한 무기물의 이탈은 작업상의 저하를 야기하게 됨은 물론 난연 효과를 저하시키게 되는 문제가 있다.Japanese Patent Publication JP2001-164031A discloses a method of coating a porous resin having a porosity with a mixture of a boron-based inorganic compound and a thermosetting resin in order to produce a porous molded article having heat resistance and flame retardancy, However, boron-based inorganic compounds such as boric acid are used as the main components of the coating mixture, and inorganic powder lumps such as glass fibers, carbon fibers, silica, talc, and the like The inorganic particles added during the drying process and the molding process of the coated expanded particles are easily separated from the inorganic particles and the separation of the inorganic substances harmful to the human body causes the deterioration of the operation and the flame retarding effect is deteriorated there is a problem.
또한, 한국 공개특허 제2007-0013367호에는 규산소다 용액에 규조토, 규석, 삼산화안티몸 등을 혼합한 액체를 성형이 완료된 스티로품에 주입하는 기술이 개시되어 있으나, 이 기술은 주입된 액체의 건조가 잘되지 않기 때문에 제품의 생산효율이 매우 낮아지는 문제가 있고, 또 스티로폼에 주입된 규산소다 액과 각종 혼합물의 화학 반응으로 인해 시간이 지날수록 스티로폼이 산화되고, 또 스티로폼에 주입된 수분이 건조되면 난연 성능이 점차적으로 소멸되는 문제가 있다.Korean Patent Laid-Open Publication No. 2007-0013367 discloses a technique of injecting a liquid mixed with diatomaceous earth, silica, and antimony trioxide into a styrofoam product which has been subjected to molding, There is a problem that the product production efficiency is very low because it does not work well and the styrofoam is oxidized as time goes by due to the chemical reaction between the sodium silicate solution injected into the styrofoam and various mixtures and when the water injected into the styrofoam is dried There is a problem that the flame retardant performance gradually disappears.
따라서, 종래 제시되고 있는 방법들에 의해 제조된 폴리스티렌 발포체나 발포성 폴리스티렌 비드들은 난연 소재의 물성 한계로 인해 난연성의 저하를 피하기 어렵다. 특히 이러한 난연성의 약화는 불연에 가까운 정도의 난연성을 유구하고 있는 국제 추세에 비추어보더라도 시급한 개선이 필요하다.Therefore, the polystyrene foam or expandable polystyrene beads produced by the conventional methods are difficult to avoid deterioration of the flame retardancy due to the physical limitations of the flame retardant material. Particularly, the weakening of the flame retardancy requires urgent improvement in view of the international tendency of flame retardancy close to flame retardancy.

상기 무기 난연재는 수산화알루미늄을 예로 들 수 있으며, 무기 난연재료에 속하는 다른 성분으로 대체 가능하다. 본 발명의 바인더에서 이러한 무기 난연재료의 비율은 바인더의 조성을 기준으로 할 때 1~10중량부인 것이 바람직하다.The inorganic flame retardant is exemplified by aluminum hydroxide, and can be replaced with other components belonging to the inorganic flame retardant. In the binder of the present invention, the ratio of the inorganic flame retardant is preferably 1 to 10 parts by weight based on the composition of the binder.
상기 산화칼슘(CaO)는 반응촉진제로 작용하고, 상기 이소시아네이트는 접착력을 높여주는 작용을 한다.The calcium oxide (CaO) serves as a reaction promoter, and the isocyanate acts to increase the adhesive strength.
상기 내수성 향상 첨가제는 열전도율의 감소 효과를 높이기 위하여 유연제, 분산제, 또는 경화제를 포함하여 이루어질 수 있고, 본 발명의 상기 바인더 조성을 기준으로 할 때 1~5중량%인 것이 바람직하다.The water resistance improving additive may include a softening agent, a dispersing agent, or a hardening agent in order to increase the effect of decreasing the thermal conductivity, and it is preferably 1 to 5 wt% based on the binder composition of the present invention.
