방염 무가교 폴리에틸렌 폼 조성물{Flame Retardant Non-Crosslinking Polyethylene Foam Composition}Flame Retardant Non-Crosslinking Polyethylene Foam Composition

발명의 분야Field of invention

본 발명은 폴리에틸렌 폼에 사용되는 방염 무가교 폴리에틸렌 조성물에 관한 것이다. 보다 구체적으로 본 발명은 폴리에틸렌 수지, 염소화 폴리에틸렌, 삼산화 안티몬, 몰리브덴 황, 스테아린산 염, 왁스, 산화방지제, 수화물 및 브롬계 화합물로 이루어지며, 폴리에틸렌 폼에 사용되는 방염 무가교 폴리에틸렌 조성물에 관한 것이다. The present invention relates to flame retardant uncrosslinked polyethylene compositions for use in polyethylene foams. More specifically, the present invention relates to a flame retardant uncrosslinked polyethylene composition composed of polyethylene resin, chlorinated polyethylene, antimony trioxide, molybdenum sulfur, stearic acid salts, waxes, antioxidants, hydrates and bromine compounds, and used in polyethylene foams.

발명의 배경Background of the Invention

폴리에틸렌 폼(P.E. Foam)은 반경질 발포체로서 단열성, 내열성, 내수성, 완충성 등이 우수하여 산업용 단열재와 자동차 및 전자부품 내장재로서 광범위하게 사용된다. 이러한 폴리에틸렌 폼에는 가교형과 무가교형이 있으며, 최근에는 가교 공정을 포함하는 단계들이 불필요하고 재활용이 가능하다는 장점 때문에 무가교 폴리에틸렌 폼이 각광받고 있다. Polyethylene foam (P.E.Foam) is a semi-rigid foam with excellent heat insulation, heat resistance, water resistance and cushioning properties. It is widely used as an industrial insulation material and automobile and electronic component interior material. Such polyethylene foams are crosslinked and uncrosslinked, and recently, uncrosslinked polyethylene foams have been in the spotlight due to the advantages that the steps including the crosslinking process are unnecessary and recyclable.

무가교 폴리에틸렌 폼은 보온, 방음, 방진 특성이 매우 우수하기 때문에 주택, 아파트 및 빌딩 등의 건축자재나 지하철과 같은 시설의 내장재로 사용되고 있으며, 이에 따라 방염성이 필수적으로 요구된다. Since non-crosslinked polyethylene foam has excellent thermal insulation, soundproofing, and dustproof properties, it is used as a building material for houses, apartments, and buildings, or as an interior material for facilities such as subways.

폴리에틸렌 폼에 방염성을 부여하기 위하여 석면이나 유리섬유 등을 첨가하는 방법이 개시되고 있다. 그러나 석면이나 유리섬유가 첨가된 제품은 시공 및 철거의 어려움이 있고, 또한 그 분진이 호흡기를 통하여 인체에 축적되어 발암을 유발하는 문제점이 있다. In order to provide flame retardancy to polyethylene foam, the method of adding asbestos, glass fiber, etc. is disclosed. However, asbestos or glass fiber added products have difficulty in construction and dismantling, and there is also a problem that the dust accumulates in the human body through the respiratory tract and causes carcinogenesis.

따라서 폴리에틸렌 폼 조성물에 방염제를 첨가하는 방법이 제기되었는데, 제품의 제조특성상 또는 제품의 성질상 방염성 무가교 폴리에틸렌 폼의 제조는 현재 극히 어려운 실정이다. 왜냐하면, 무가교 폴리에틸렌 폼은 제조공정 중에 가스를 주입하여 폴리에틸렌 수지를 발포하기 때문에, 가스 주입시 제조기계인 압출기가 급냉이 되어 기계내부에서 압력이 급상승하게 되고, 이로 인해 방염제가 균일한 제품을 생산할 수 없기 때문이다. 따라서 방염제 사용시 내부압력증가와 흐름성 장애를 극복하기 위해서는 기존의 기계를 변경하거나 설계를 변형하여야 한다.Therefore, a method of adding a flame retardant to the polyethylene foam composition has been proposed, but the production of flame-retardant non-crosslinked polyethylene foam due to the nature of the product or the nature of the product is currently extremely difficult situation. Because the non-crosslinked polyethylene foam foams polyethylene resin by injecting gas during the manufacturing process, the extruder, which is a manufacturing machine, becomes quenched during gas injection, and the pressure rises rapidly inside the machine, thereby producing a uniform flame retardant product. Because you can't. Therefore, to overcome the increase of internal pressure and flow impairment when using flame retardant, the existing machine should be changed or the design modified.

일본특허공개 평2-73835호에서는 폴리에틸렌, 에틸렌비스테트라브로모프탈이미드 및 클로로파라핀등으로 이루어진 난연성 폴리에틸렌 폼을 개시하고 있다. 그러나 상기 기술은 가교형 폴리에틸렌을 사용한 것으로 별도의 가교제 및 가교공정이 필요하다는 단점이 있다. Japanese Patent Laid-Open No. 2-73835 discloses a flame retardant polyethylene foam made of polyethylene, ethylene bistetrabromophthalimide, chloroparaffin, and the like. However, the technique uses a crosslinked polyethylene, which requires a separate crosslinking agent and a crosslinking process.

따라서 본 발명자는 상기의 문제점을 극복하기 위하여, 무가교 폴리에틸렌 수지에 방염성을 부여하기 위해 염소화 폴리에틸렌, 삼산화 안티몬, 수화물 및 브롬 화합물을 사용하고, 생산의 용이성과 제품의 불량을 개선하기 위해 몰리브덴 황, 스테아린산 염 및 왁스를 첨가하며, 또한 제품의 균일성을 위해 일정 흐름성(MI) 범위를 갖는 폴리에틸렌 수지를 사용함으로써, 방염성이 우수할 뿐만 아니라, 작업이 용이하고, 환경 친화적인 무가교 폴리에틸렌 폼 조성물을 개발하기에 이른 것이다. Therefore, the present inventors use chlorinated polyethylene, antimony trioxide, hydrates and bromine compounds to impart flame retardance to uncrosslinked polyethylene resins in order to overcome the above problems, and to improve the ease of production and product defects, molybdenum sulfur, By adding stearic acid salts and waxes and using a polyethylene resin having a constant flowability (MI) range for uniformity of the product, it is not only excellent in flame retardancy, but also easy to work with, and is environmentally friendly. It is early to develop.

본 발명의 목적은 방염성이 우수한 무가교 폴리에틸렌 폼 조성물을 제공하기 위한 것이다. An object of the present invention is to provide a non-crosslinked polyethylene foam composition excellent in flame resistance.

본 발명의 다른 목적은 압출기 작동시 부하 문제가 없이 작업이 용이한 방염 무가교 폴리에틸렌 폼 조성물을 제공하기 위한 것이다. Another object of the present invention is to provide a flame-retardant non-crosslinked polyethylene foam composition that is easy to work with no load problems when operating the extruder.

본 발명의 또 다른 목적은 기존의 기계를 변경이나 변형시키지 않고 기존의 장비로도 생산할 수 있는 방염 무가교 폴리에틸렌 폼 조성물을 제공하기 위한 것이다. It is another object of the present invention to provide a flame retardant uncrosslinked polyethylene foam composition which can be produced with existing equipment without altering or modifying existing machines.

본 발명의 또 다른 목적은 균일성이 우수한 방염 무가교 폴리에틸렌 폼 조성물을 제공하기 위한 것이다. Still another object of the present invention is to provide a flame retardant non-crosslinked polyethylene foam composition having excellent uniformity.

본 발명의 또 다른 목적은 석면을 함유하지 않아 환경 친화적인 무가교 폴리에틸렌 폼 조성물을 제공하기 위한 것이다. Another object of the present invention is to provide an environment-friendly non-crosslinked polyethylene foam composition containing no asbestos.

본 발명의 상기 및 기타 목적들은 하기 설명되는 본 발명에 의하여 모두 달성될 수 있다. The above and other objects of the present invention can be achieved by the present invention described below.

본 발명의 방염 폴리에틸렌 조성물은 폴리에틸렌 100 중량부, 염소화 폴리에틸렌 10 내지 50 중량부, 삼산화 안티몬 1 내지 20 중량부, 몰리브덴 황 1 내지 5 중량부, 스테아린산 염 0.1 내지 5 중량부, 왁스 0.1 내지 5 중량부 및 산화방지제 0.1 내지 3 중량부로 이루어지며, 선택적으로 금속 수화물 0 내지 20 중량부 및 브롬 화합물 0 내지 30 중량부를 더 포함할 수 있다. 또한 본 발명의 방염 무가교 폴리에틸렌 폼 조성물은 경탄이나 탈크를 0 내지 30 중량부 더 포함할 수 있다. 이하, 본 발명의 각 성분에 대해 하기에 상세히 설명한다. Flame retardant polyethylene composition of the present invention is 100 parts by weight of polyethylene, 10 to 50 parts by weight of chlorinated polyethylene, 1 to 20 parts by weight of antimony trioxide, 1 to 5 parts by weight of molybdenum sulfur, 0.1 to 5 parts by weight of stearic acid salt, 0.1 to 5 parts by weight of wax And 0.1 to 3 parts by weight of an antioxidant, and optionally 0 to 20 parts by weight of a metal hydrate and 0 to 30 parts by weight of a bromine compound. In addition, the flame-retardant non-crosslinked polyethylene foam composition of the present invention may further comprise 0 to 30 parts by weight of hard coal or talc. Hereinafter, each component of this invention is demonstrated in detail below.

상기 폴리에틸렌은 저밀도폴리에틸렌(LDPE)을 사용하며, 흐름성(MI)이 1 g/10min 내지 5 g/10min 인 것이 바람직하다. 흐름성(MI)이 1 g/10min 미만이거나 5 g/10min을 초과할 경우 제품의 균일성에 좋지 않은 영향을 준다. The polyethylene uses low density polyethylene (LDPE), and the flowability (MI) is preferably 1 g / 10min to 5 g / 10min. Flowability (MI) below 1 g / 10min or above 5 g / 10min adversely affects product uniformity.

본 발명에서 염소화 폴리에틸렌(CPE)은 기초수지인 폴리에틸렌 수지에 방염성을 부여하기 위하여 첨가하며, 염소함량이 20 내지 70 중량%인 것을 사용하는 것이 바람직하다. In the present invention, chlorinated polyethylene (CPE) is added to impart flame retardancy to polyethylene resin, which is a basic resin, and it is preferable to use a chlorine content of 20 to 70 wt%.

상기 염소화 폴리에틸렌은 폴리에틸렌 수지 100 중량부에 대하여 10 내지 50 중량부로 사용된다. 염소화 폴리에틸렌을 10 중량부 미만으로 사용할 경우 방염 효과가 미미하며, 50 중량부를 초과하여 첨가할 경우 충분한 유연성을 얻을 수 없기 때문에 바람직하지 않다. The chlorinated polyethylene is used in 10 to 50 parts by weight based on 100 parts by weight of polyethylene resin. When the chlorinated polyethylene is used in less than 10 parts by weight, the flame retardant effect is insignificant, and when it is added in excess of 50 parts by weight, it is not preferable because sufficient flexibility cannot be obtained.

본 발명의 삼산화안티몬은 방염성을 향상시키기 위해 첨가하는 것으로 순도가 90 % 이상인 제품을 사용한다. 상기 삼산화안티몬은 폴리에틸렌 수지 100 중량부에 대하여 1 내지 20 중량부로 사용된다. 삼산화안티몬을 1 중량부 미만 사용할 경우 방염성 향상의 효과가 충분히 발휘되지 않으며, 또한 20 중량부 보다 큰 경우에는 작업성이 저하되는 등의 결점이 나타난다. The antimony trioxide of the present invention is added to improve the flame retardancy and uses a product having a purity of 90% or more. The antimony trioxide is used in 1 to 20 parts by weight based on 100 parts by weight of polyethylene resin. If less than 1 part by weight of antimony trioxide is used, the effect of improving the flame retardancy is not sufficiently exhibited, and if it is larger than 20 parts by weight, defects such as deterioration of workability appear.

본 발명에서 몰리브덴 황은 작업의 용이성과 압출기 생산공정에서의 부하가 걸리는 문제를 해결하기 위해 첨가된다. 상기 몰리브덴 황은 폴리에틸렌 수지 100 중량부에 대하여 1 내지 5 중량부로 첨가된다. 상기 몰리브덴 황 외에도 불소 화합물을 대체하여 첨가할 수 있다. In the present invention, molybdenum sulfur is added to solve the problem of ease of operation and load in the extruder production process. The molybdenum sulfur is added in 1 to 5 parts by weight based on 100 parts by weight of polyethylene resin. In addition to the molybdenum sulfur may be added to replace the fluorine compound.

본 발명의 스테아린산 염은 아연 스테아린산, 칼슘 스테아린산, 마그네슘 스테아린산 및 알루미늄 스테아린산으로 이루어진 군으로부터 선택되며, 생산의 용이성과 제품 불량을 개선하기 위하여 첨가된다. 본 발명에서 상기 스테아린산 염은 0.1 내지 5 중량부로 사용된다. The stearic acid salt of the present invention is selected from the group consisting of zinc stearic acid, calcium stearic acid, magnesium stearic acid and aluminum stearic acid, and is added to improve the ease of production and product defects. In the present invention, the stearic acid salt is used in 0.1 to 5 parts by weight.

본 발명에서 왁스는 저밀도 폴리에틸렌 왁스와 변성 폴리에틸렌 왁스가 사용되며, 생산의 용이성과 제품 불량을 개선하기 위하여 첨가된다. 상기 왁스는 폴리에틸렌 수지 100 중량부에 대하여 0.1 내지 5 중량부로 사용된다. In the present invention, the wax is used a low density polyethylene wax and modified polyethylene wax, and added to improve the ease of production and product defects. The wax is used in an amount of 0.1 to 5 parts by weight based on 100 parts by weight of polyethylene resin.

본 발명의 산화방지제는 통상적으로 사용되는 페놀계, 인계, 황계 및 아민계 산화방지제가 사용될 수 있으며, 수지 조성물의 산화방지 및 제품의 균일성을 부여하는 역할을 한다. 상기 산화방지제는 폴리에틸렌 수지 100 중량부에 대하여 0.1 내지 3 중량부로 사용된다. 산화방지제가 0.1 중량부 미만으로 첨가될 경우 제품의 균일성에 바람직하지 않으며, 3 중량부를 초과하여 첨가할 경우 물성 발란스에 좋지 않은 영향을 미친다. Antioxidants of the present invention may be used phenol-based, phosphorus-based, sulfur-based and amine-based antioxidants commonly used, and serves to prevent the oxidation of the resin composition and to give uniformity of the product. The antioxidant is used in 0.1 to 3 parts by weight based on 100 parts by weight of polyethylene resin. If the antioxidant is added in less than 0.1 parts by weight is not preferable to the uniformity of the product, when added in excess of 3 parts by weight adversely affects the physical balance.

본 발명의 폴리에틸렌 폼 조성물은 선택적으로 금속 수화물을 더 첨가할 수 있다. 상기 금속 수화물로는 수산화 알루미늄, 수산화 마그네슘이 사용될 수 있으며, 수지 조성물의 방염성을 향상시킨다. 본 발명의 금속 수화물은 폴리에틸렌 수지 100 중량부에 대하여 0 내지 20 중량부로 사용된다. 금속 수화물을 20 중량부 초과하여 첨가할 경우, 충격강도 등의 기계적 강도를 저하시킨다. The polyethylene foam composition of the present invention may optionally further add a metal hydrate. As the metal hydrate, aluminum hydroxide and magnesium hydroxide may be used, thereby improving the flame resistance of the resin composition. The metal hydrate of the present invention is used in an amount of 0 to 20 parts by weight based on 100 parts by weight of polyethylene resin. When more than 20 parts by weight of the metal hydrate is added, mechanical strength such as impact strength is lowered.
