Abstract
본 발명은 발포성 방음 방염 단열재에 대한 것으로 더욱 상세하게는 기존의 단열재의 문제인 화재에 취약하며 방염효력이 있는 제품은 비록 화재에 잘 타지 않으나 화염 또는 열을 내부로 전이 되는 것을 막는 기능은 가지고 있지 못하여 결국 내부에서 발화가 발생하여 화재를 더 욱 크게 만드는 문제점을 친환경 무독성 소재로 만든 발포성 불연소재의 스펀지와 얇은 소재이면서도 단열재의 기능을 하는 Oxy-pad소재 또는 스티로폼 패널과 같은 두 철판과의 결합으로 기존의 단열재의 문제를 해결하는 것에 대한 것이다.
본 발명은, EVA 50~60 중량%, 인 계 난연제 5~10 중량%, 산화알루미늄(Al(OH3)) 및 징크보레이트(Zinc Borate) 억연제 3~7 중량%, 팽창 흑연 12~23 중량%을 포함하는 난연 조성물로 친환경 난연성 EVA패널을 제조함을 특징으로 한다.More particularly, the present invention relates to a foamed soundproof flame retardant insulation material, which is susceptible to fire, which is a problem of conventional insulation materials, and which has flame retardant effect, does not have a function to prevent flame or heat from being transferred to the inside, As a result, the problem of making the fire even more by the internal ignition is caused by the combination of the sponge made of environmentally friendly non-toxic material and the sponge made of non-toxic material and the double plate such as the Oxy-pad material or the styrofoam panel, To solve the problem of the heat insulator.
The present invention relates to a method for producing a flame retardant resin composition comprising 50 to 60% by weight of EVA, 5 to 10% by weight of a phosphorus-based flame retardant, 3 to 7% by weight of aluminum oxide (Al (OH3)) and Zinc Borate, 12 to 23% Flame retardant EVA panel is produced by using a flame retardant composition comprising the flame retardant composition.
Description
본 발명은 친환경 난연성 EVA패널에 관한 것으로서, 더욱 상세하게는 단열, 흡음성 등이 탁월하여 건물내장재 등으로 널리 사용되는 EVA(Ethylene Vinyl Acetate)패널 제조에 있어서, 화재에 취약한 약점을 보완하여 화재 전이를 막고 유독가스가 생성되지 않도록 난연 조성물을 조성하여 난연성 EVA패널을 제조함으로써 화재로 인한 피해를 최소화하고 인명과 재산을 보호할 수 있도록 한 친환경 난연성 EVA패널에 관한 것이다.The present invention relates to an environmentally friendly flame retardant EVA panel, and more particularly, to an ethylene vinyl acetate (EVA) panel having excellent heat insulation and sound absorption properties and widely used as a building interior material, Flame retardant EVA panel is manufactured by forming a flame retardant composition so as not to generate a toxic gas, thereby minimizing damage caused by fire and protecting life and property.
급변하는 날씨와 에너지 자원에 대한 가격 상승 및 생산의 축소로 단열재에 대한 기능과 설치에 대한 규정을 국제적으로 강화시키고 있는 현실 속에서 단열재가 화재진압에 큰 문제를 가져다주는 요소로 지적받는 경우는 매우 많다.As a result of the rapid increase in the prices of the weather and energy resources and the reduction of the production, the regulations on the function and installation of the insulation are being strengthened internationally. many.
이에 따라 소방산업기술의 발달로 화재의 가능성이 있는 건축자재 또는 소방 대상물을 전기적, 기계적 또는 화학적 장치를 통해 예방을 하고 있지만 화재 발생은 더욱 빈번하고 크게 발생되고 있는 추세에 있으며, 화재발생 상황에서 심한 피해를 주거나 화재 진압에 어려움을 주는 단열재 등은 방염의 기능을 인정받은 제품만 사용토록 법으로 정하고 있음에도 아직 단열재에 대한 방염효과는 미미한 실정이며 화재시 유독가스 발생과 화재전이에 대한 부분 역할도 하고 있다.As a result, the development of fire-fighting industry technology has prevented the construction materials or fire-fighting objects that are likely to be a fire through electrical, mechanical, or chemical devices, but the fire is occurring more frequently and more frequently. Although the insulation is used only for the products that are approved for the function of flame-proofing, the effect of flame-proofing on the insulation is still insignificant. Also, it plays a role in the generation of toxic gas and fire transfer have.
일례로 스티로폼을 이용한 단열재 샌드위치 패널은 가장 주되게 사용되는 제품이면서 화재에 가장 취약한 제품으로 화재가 발생하면 패널 내부에 있는 스티로폼은 낮은 인화점으로 인해 주변의 고온에도 화염이 인가되며 양면의 철판에 의해 소화 진화 시에 소화액이 패널 내부로 주입되지 않아 소화진화에 대단히 어려움을 주고 있다. 이하에는 기존의 다양한 방염, 난연 제품과 기술 등을 참고문헌을 통해 살펴본다.For example, a panel of insulating material using styrofoam is the most commonly used product, but it is the most vulnerable to fire. When a fire occurs, styrofoam inside the panel is flame-ignited due to its low flash point, The digestion liquid is not injected into the panel at the time of evolution, and it is very difficult for the digestion to evolve. Hereinafter, various existing flame retardant and flame retardant products and technologies will be referred to through reference literature.

상기에서 다양한 난연 제품 등을 살펴보았으나 이하에는 본 발명과 직접 관련되는 EVA소재 패널에 대해 살펴본다. Various flame retardant products have been discussed above. Hereinafter, EVA material panels directly related to the present invention will be described.
EVA소재를 발포 성형기에서 패널,보드 등의 형태로 발포 성형한 성형체(이하, EVA패널이라 함.)는 그 특성이 무독성이면서 경량성, 보온성, 단열성 및 방음성이 매우 우수하고 생산비용이 비교적 저렴한 장점을 갖추고 있어 보온, 단열, 방음 등을 목적으로 하는 각종의 내외장재로 널리 사용되고 있다.A molded article (hereinafter referred to as EVA panel) formed by foam molding of an EVA material in the form of a panel or board in a foam molding machine has excellent characteristics such as non-toxicity, light weight, heat insulation property, heat insulation property and sound insulation property, And is widely used as various kinds of interior and exterior materials for the purpose of keeping warm, insulating, and soundproofing.
그러나 상기한 장점을 갖춘 EVA패널은 발포수지체로 내화성이 매우 불량하여 화재발생시 유해가스와 화염 발생, 화염의 전이(傳移)가 심한 문제점이 있다.However, the EVA panel having the above advantages has a problem that the fire resistance is very poor due to the foamed resin body, and the generation of the noxious gas, the flame and the transfer of the flame are severe when the fire occurs.
이를 더욱 구체적으로 살펴본다.We will examine this more specifically.
EVA소재는 무독성으로서 유연성이 뛰어나며, 충격에 강하여 충격 방지 및 충격 흡수기능이 뛰어나다.The EVA material is non-toxic, has excellent flexibility, and is resistant to shocks and has superior impact resistance and shock absorption.

It is widely used for shoe sole, cable, solar light sheet, hot melt adhesive, coating, and simple sponge.
이러한 EVA소재의 많은 제품 중 EVA패널은 단열성, 흡음성 등이 뛰어난 것으로 평가받고 있으나 일반 스티로폼 단열재보다 무겁다는 단점을 가지고 있고, 제조 시에 첨가되는 많은 휘발성 또는 유기성 첨가물로 인해 화염과 고온에 취약하다는 문제점을 가지고 있다.Among these EVA materials, EVA panel is evaluated as excellent in heat insulation and sound absorption, but it has a disadvantage that it is heavier than general styrofoam insulation, and it is vulnerable to flame and high temperature due to many volatile or organic additives added at the time of manufacture Lt; / RTI >

Oxy-PAN fibers have a fine fiber structure and strong mechanical properties. They have a good role as a heat insulating material, , Which are disclosed in References 12 to 15 and the like.
상기한 바와 같이 EVA는 무독성으로 경량성, 보온성, 단열성, 방음성 및 경제성이 뛰어난 반면에 열가소성 발포수지체로서 내열성이 불량한 결함을 가지고 있다.As described above, EVA is non-toxic and has excellent lightweight properties, thermal insulation properties, heat insulation properties, soundproofing properties and economical properties, but has defects in heat resistance as thermoplastic foamed resin materials.
이에 본 발명은 EVA패널의 취약한 내화성을 극복할 수 있도록 EVA패널의 발포, 성형과정에서 EVA에 난연제 조성물을 혼합하여 발포, 성형하는 방법으로 EVA에 난연성을 부여함으로써 우수한 방염(난연)기능을 발휘할 수 있는 EVA패널을 제공하고자 한다.Accordingly, the present invention provides a method of foaming and molding EVA by mixing a flame retardant composition with EVA during the foaming and molding of the EVA panel so as to overcome the weak fire resistance of the EVA panel, thereby providing EVA with flame retardancy, I would like to offer an EVA panel.
즉, 본 발명은 EVA패널에 난연성을 부여하여 화염의 열로 인한 파괴는 물론 연소에 의한 유독가스가 발생되지 않으면서 자기소화성이 없어 주변 화재 열로 인해 쉽게 화염이 인가되는 취약성을 해결하여 내화성, 난연성을 갖도록 한 것에 그 특징이 있다.That is, according to the present invention, the EVA panel is provided with flame retardancy, so that not only destruction due to the heat of the flame but also toxic gas caused by the combustion is not generated, so there is no self-extinguishing property.

이하에 실시예와 첨부한 도면을 통해 본 발명을 보다 상세히 설명한다. Hereinafter, the present invention will be described in more detail with reference to examples and attached drawings.
첨부된 도면은 본 발명의 기술적 사상의 내용과 범위를 쉽게 설명하기 위한 예시일 뿐 이에 의해 본 발명의 기술적 범위가 한정되거나 변경되는 것은 아니다.The accompanying drawings are merely examples for the purpose of easily explaining the content and scope of the technical idea of the present invention, and thus the technical scope of the present invention is not limited or changed.
또한 이러한 예시에 기초하여 본 발명의 기술적 사상의 범위 안에서 다양한 변형과 변경이 가능함은 당업자에게는 당연하다.It is obvious to those skilled in the art that various changes and modifications can be made within the scope of the technical idea of the present invention based on these examples.
본 발명은 EVA에 난연 조성물을 첨가하여 EVA패널을 제조하는 것으로, EVA패널의 발포, 성형 등에 따른 제조 과정과 방법 등은 이미 당해 기술분야에서 공지된 기술이며, 본 발명에서 언급하는 EVA패널의 제조 즉, 발포, 성형 등의 과정을 이루어지는 제조방법은 공지의 기술을 그대로 적용하는 것이므로 이에 대한 언급은 생략한다.
The present invention relates to a process for producing an EVA panel by adding a flame retardant composition to EVA, and a manufacturing process and a method according to foaming and molding of the EVA panel are already known in the art, and the manufacture of the EVA panel That is, the manufacturing method for performing the processes such as the foaming and the molding is applied to a known technology as it is, so that a description thereof will be omitted.
[실시예1][Example 1]
EVA 50~60 중량%에 대하여;For 50 to 60 wt% EVA;
난연제 5~10 중량%; 억연제 3~7 중량%, 팽창 흑연 12~23 중량%를 혼합하여 난연 조성물을 조성하고 성형기에서 발포,성형하여 EVA패널을 제조한다.5 to 10% by weight of a flame retardant; A flame retardant composition is prepared by mixing 3 to 7% by weight of expanding agent and 12 to 23% by weight of expanded graphite, and foamed and molded by a molding machine to produce an EVA panel.
상기에서 난연제는 알려진 바와 같이 브롬계, 인계, 염소계, 무기계 등으로 나누어 볼 수 있으나, 본 발명에서는 EVA에 맞는 난연제로 인 계열을 선택, 사용한다. 물론 브롬계 및 무기계에서도 같은 성질의 난연제를 찾을 수 있다.The flame retardant may be classified into bromine, phosphorus, chlorine, and inorganic. However, in the present invention, phosphorus is selected and used as a flame retardant suitable for EVA. Of course, flame retardants of the same nature can be found in both bromine and inorganic systems.
또, 억연제는 가장 알려진 산화알루미늄(Al2O3) 및 징크보레이트(Zinc Borate)를 사용하며, 이외에도 공지의 다른 억연제를 선택하여 사용할 수 있다. In addition, the oxidizing agent uses the most known aluminum oxide (Al 2 O 3 ) and zinc borate, and other known oxidizing agents can be selected and used.
또, 팽창 흑연은 발포입자경의 크기에 따라 300mesh ~ 50mesh 등으로 다양한 mesh 종류가 있는데 본 발명에서는 100~80mesh 사이를 사용하고자 한다.The expanded graphite has various mesh types ranging from 300 mesh to 50 mesh depending on the size of the expanded particle diameter. In the present invention, the range of 100 to 80 mesh is used.
그러나 사용하고자 하는 용도에 따라 팽창 흑연의 mesh는 다양하게 선택할 수 있다. 즉, 제조하고자 하는 EVA패널의 폭(두께), 용도, 목적에 따라 최적의 발포입도를 가질 수 있도록 선택되어질 것이다. However, the mesh of expanded graphite can be variously selected depending on the intended use. That is, it will be selected so as to have an optimal foam particle size depending on the width (thickness) of the EVA panel to be manufactured, the application, and the purpose.
한편, 상기 조성된 난연 조성물에 팽창 흑연의 발포 증폭을 위해 EVA 파우더를 더 포함하여 실시할 수 있다.On the other hand, EVA powder may be further added to the flame retardant composition to amplify expansion of expanded graphite.
즉, 상기 난연 조성물에 대해 100: 5~10의 중량비로 EVA 파우더를 더 포함하여 실시할 수 있으며, 이 경우 액상 EVA도 가능하나 가공 상의 편리를 위해 EVA 파우더를 권한다.That is, the EVA powder may be further added to the flame retardant composition at a weight ratio of 100: 5 to 10, and in this case, liquid EVA may be used, but EVA powder is recommended for convenience of processing.
상기한 난연 조성물로 이루어져 성형기에서 발포, 성형되는 EVA패널은 불연성을 갖는 난연 발포체로 내부에 다공성의 방화층이 형성되어 EVA패널 표면에 800℃의 화염이 직접 닿게하여 시험한 결과 20분간 연소되지 않는 불연성을 나타내었다.The EVA panel made of the above-mentioned flame retardant composition and foamed and molded in a molding machine is a nonflammable flame-retarded foam, and a porous fireproof layer is formed in the inside. A flame of 800 ° C is directly applied to the surface of the EVA panel. Non-combustible.
이러한 시험결과는 건축물의 내장재료 및 구조의 난연성 시험방법(KS F2271)에 따른 난연 테스트의 난연 3급에 준하는 불연성 성능이다.
These test results are nonflammability equivalent to flame retardant grade 3 in the flame retardant test according to the flame retardancy test method (KS F2271) of the interior materials and structures of buildings.

상기에서 펄라이트는 충전제(Filler)로서 단열제, 방음제, 난연제, 경량성, 그리고 흡음성이 뛰어나며 가격이 저렴하여 EVA패널 제품화에 유리한 점을 가지고 있다.In the above, pearlite is excellent as a filler as a heat insulating material, a soundproofing agent, a flame retardant, a light weight, and a sound absorbing property, and is inexpensive and advantageous for EVA panel production.
특히 무독, 무미, 불연, 산, 알칼리에 견디며, 단열보온자재, 그리고 토양개량 등 다양한 산업분야에 응용하여 사용되고 있다.Especially, it is used for various industrial fields such as non-toxic, tasteless, incombustible, acidic, alkali resistant, heat insulating material, and soil improvement.
상기 펄라이트에 대해서는 후술하는 시험예에서 상세히 살펴본다.The pearlite will be described in detail in Test Examples to be described later.
그리고 상기 난연제, 억연제, 팽창 흑연 등의 조성물은 전술한 실시예1과 동일한 것으로 중복되는 설명에도 불구하고 이를 다시 살펴본다. The composition of the flame retardant, the opacifying agent, and the expanded graphite is the same as that of the first embodiment, and will be described again in spite of the redundant explanation.
난연제는 알려진 바와 같이 브롬계, 인계, 염소계, 무기계 등으로 나누어 볼 수 있으나, 본 발명에서는 EVA에 맞는 난연제로 인 계열을 선택, 사용한다. 물론 브롬계 및 무기계에서도 같은 성질의 난연제를 찾을 수 있다.As known, the flame retardant can be divided into bromine, phosphorus, chlorine, and inorganic. In the present invention, phosphorus is selected and used as a flame retardant suitable for EVA. Of course, flame retardants of the same nature can be found in both bromine and inorganic systems.
억연제는 가장 알려진 산화알루미늄(Al2O3) 및 징크보레이트(Zinc Borate)를 사용하며, 이외에도 공지의 다른 억연제를 선택하여 사용할 수 있다. Aluminum oxide (Al 2 O 3 ) and zinc borate are the most commonly used oxidizing agents, and other known oxidizing agents can be selected and used.
팽창 흑연은 발포입자경의 크기에 따라 300mesh ~ 50mesh 등으로 다양한 mesh 종류가 있는데 본 발명에서는 100~80mesh 사이를 사용하고자 한다.Expanded graphite has various mesh types such as 300 mesh to 50 mesh depending on the size of the expanded particle size. In the present invention, it is desired to use 100 to 80 mesh.
그러나 사용하고자 하는 용도에 따라 팽창 흑연의 mesh는 다양하게 선택할 수 있다. 즉, 제조하고자 하는 EVA패널의 폭(두께), 용도, 목적에 따라 최적의 발포입도를 가질 수 있도록 선택되어질 것이다. However, the mesh of expanded graphite can be variously selected depending on the intended use. That is, it will be selected so as to have an optimal foam particle size depending on the width (thickness) of the EVA panel to be manufactured, the application, and the purpose.
한편, 상기 조성된 난연 조성물에 팽창 흑연의 발포 증폭을 위해 EVA 파우더를 더 포함하여 실시할 수 있다.On the other hand, EVA powder may be further added to the flame retardant composition to amplify expansion of expanded graphite.
즉, 상기 난연 조성물에 대해 100: 5~10의 중량비로 EVA 파우더를 더 포함하여 실시할 수 있으며, 이 경우 액상 EVA도 가능하나 가공 상의 편리를 위해 EVA 파우더를 권한다.That is, the EVA powder may be further added to the flame retardant composition at a weight ratio of 100: 5 to 10, and in this case, liquid EVA may be used, but EVA powder is recommended for convenience of processing.
상기 난연 조성물로 이루어져 성형기에서 발포, 성형되는 EVA패널은 불연성을 갖는 난연 발포체로 내부에 다공성의 방화층이 형성되어 EVA패널 표면에 800℃의 화염이 직접 닿게하여 시험한 결과 상기 실시예1의 경우에서와 같이 20분간 연소되지 않는 불연성을 나타내었다.
The EVA panel made of the flame retardant composition and foamed and molded in a molding machine is a flame-retardant foam having a nonflammable property. A porous fireproof layer is formed on the inside of the EVA panel and the flame directly contacts the surface of the EVA panel. The incombustibility was not burned for 20 minutes.
[시험예][Test Example]
펄라이트는 많은 기능을 가지고 있다. 그러나 많이 넣는다고 펄라이트만의 기능이 계속 향상되는 것이 아님을 아래 표 1의 가스토치 시험에서 알 수 있는데, EVA 패널 뒤쪽에 온도계를 놓고 가스토치로 불을 붙였을 때 후면의 온도변화를 측정하였다.Perlite has many features. However, it can be seen from the gas torch test of Table 1 that the function of perlite alone is not improved continuously. However, when the thermometer is placed behind the EVA panel and the gas torch is lit, the temperature change of the rear surface is measured.
본 시험에서 15% 이상의 배합은 열 차단에 있어 큰 효과를 보여주지 못함을 알 수 있으며, 이는 펄라이트와 EVA 패녈 제작 시 균일한 분산에 영향을 미치고 있는 것으로 사료된다.It can be seen that the combination of 15% or more in this test does not show a great effect on the heat shielding, which is considered to affect the uniform dispersion in the manufacture of pearlite and EVA panel.
