장식시트용 난연제 조성물 및 이를 이용한 장식시트{Fire retardant composition and decorative sheet using the same}Flame retardant composition and decorative sheet using the same

본 발명은 방염성능이 우수한 장식시트용 난연제 조성물 및 장식시트에 관한 것으로서, 보다 상세하게는 실리케이트, 인계 난연제 및 수산화알루미늄 및/또는 수산화마그네슘을 포함하여 이루어지므로써 방염성능이 우수한 장식시트용 난연제 조성물 및 이를 이용한 장식시트에 관한 것이다.The present invention relates to a decorative sheet flame retardant composition and a decorative sheet having excellent flame retardant performance, and more particularly, comprising a silicate, phosphorus-based flame retardant and aluminum hydroxide and / or magnesium hydroxide, and thus excellent flame retardant composition for decorative sheet. And it relates to a decorative sheet using the same.

장식시트와 같은 표면마감재는 재료를 보호하고 외관을 다양한 색상과 질감으로 표현한 마감재를 일컫는 것으로, 특히 실내 인테리어용품 건자재나 가구, 책상 등의 표면을 장식하는 재료로 많이 사용된다.Surface finishing materials, such as decorative sheets, refers to a finishing material that protects the material and expresses the exterior in various colors and textures, and is particularly used as a material for decorating interior surfaces, building materials, furniture, and desks.

한편, 화재에 대한 위험이 부각된 초기에는 방염성의 목적을 단순하게 화염의 전파 방지와 지연에 두었지만, 근래 들어 화재발생시 가장 문제점이 되는 연기의 발생으로 시야 확보가 불가능해지고, 유독가스를 포함하는 것이 가장 큰 문제점으로 대두되고 있기에, 기존의 화염 전파 방지 성능을 그대로 유지한 상태에서 연기밀도 저감 효과를 확보할 수 있는 기술 개발이 진행되고 있다.On the other hand, in the early days when the danger of fire was highlighted, the purpose of flame retardancy was simply to prevent and delay the propagation of flames. Since this is the biggest problem, the development of technology to secure the smoke density reduction effect while maintaining the existing flame propagation prevention performance is in progress.

상기 문제점을 해결하기 위한 방법으로 표면마감재용 조성물에 수산화물을 다량 투입하여 연기밀도 저감 효과를 얻을 수 있으나, 이 경우 다량의 수산화물로 인해 PVC와의 상용성, 가공성과 기계적 물성을 저하시키는 문제점이 발생하였다.As a method for solving the above problems, a large amount of hydroxide can be added to the surface finish composition to reduce the smoke density, but in this case, a large amount of hydroxide causes a problem of decreasing compatibility, processability, and mechanical properties with PVC. .

본 발명의 목적은 상기와 같은 문제점을 해결하기 위하여, 표면마감재인 장식시트용 난연제 조성물에 PVC와 상용성이 우수한 실리케이트, 인계 난연제, 수산화알루미늄 등을 적용하므로써 방염성능이 우수한 장식시트용 난연제 조성물을 제공하는 것이다.An object of the present invention to solve the above problems, by applying a silicate, phosphorus-based flame retardant, aluminum hydroxide and the like excellent in compatibility with PVC to the decorative sheet flame retardant composition as a surface finishing material, the decorative sheet flame retardant composition excellent in flame resistance performance To provide.

본 발명의 장식시트용 난연제 조성물은 실리케이트 1~30중량부, 인계 난연제 1~40중량부, 수산화알루미늄 및 수산화마그네슘에서 선택되는 1종 이상 2~70중량부를 포함하는 것을 특징으로 한다.Flame retardant composition for a decorative sheet of the present invention is characterized in that it comprises 1 to 30 parts by weight of silicate, 1 to 40 parts by weight of phosphorus-based flame retardant, at least 2 to 70 parts by weight selected from aluminum hydroxide and magnesium hydroxide.

본 발명에서 사용되는 실리케이트계와 인계 난연제는 서로 혼합하여 800℃ 이상에서 액상을 형성하며, 면에 고르게 분포하여 화염과 기재 사이에 막을 형성하며, 화염의 전파를 차단하는 역할을 한다. The silicate-based and phosphorus-based flame retardants used in the present invention are mixed with each other to form a liquid at 800 ℃ or more, evenly distributed on the surface to form a film between the flame and the substrate, and serves to block the propagation of the flame.

본 발명에서 사용되는 실리케이트는 1~30중량부 사용되는 것이 바람직한데, 사용량이 1중량부 미만인 경우에는 화염과 기재 사이에서 화염 차단이 미미하여 바람직하지 않고, 30중량부를 초과하는 경우에는 화염 차단은 우수하나 장식시트의 면상태가 균일하지 않기 때문에 바람직하지 않다. It is preferable that the silicate used in the present invention is used in an amount of 1 to 30 parts by weight, but when the amount is less than 1 part by weight, the flame is not preferable between the flame and the substrate, which is not preferable. However, it is not preferable because the surface state of the decorative sheet is not uniform.

본 발명에서 사용되는 인계 난연제로는 크레실 디페닐 포스페이트, 트리크레실 포스페이트, 트리크실릴 포스페이트, 트리페닐 포스페이트, 레졸시놀 비스(디페 닐 포스페이트) 등을 들 수 있으며, 상기 인계 난연제는 1~40중량부 사용되는 것이 바람직한데, 사용량이 1중량부 미만인 경우에는 상기 실리케이트의 막 형성시까지 화염 방지효과가 미미하여 바람직하지 않고, 40중량부를 초과하는 경우에는 화염 방지효과는 우수하지만 장식시트의 면상태가 균일하지 않아 바람직하지 않다.Examples of the phosphorus flame retardant used in the present invention include cresyl diphenyl phosphate, tricresyl phosphate, trixylyl phosphate, triphenyl phosphate, resorcinol bis (diphenyl phosphate), and the like. It is preferable to use 40 parts by weight, but if the amount is less than 1 part by weight, the effect of preventing flame is insignificant until the formation of the silicate film. It is not preferable because the state is not uniform.

본 발명에서 사용되는 수산화알루미늄은 수화물이 발열 과정의 열을 흡수하고, 수산화알루미늄의 산화과정에서 발생하는 산화알루미늄은 저연 효과를 나타낸다. 수산화알루미늄 대신에 유사한 특성을 나타내는 수산화마그네슘으로 동량 대체가 가능하고, 또는 수산화알루미늄과 수산화마그네슘을 혼합하여 사용하는 것도 가능하며, 이때 혼합비에는 특별한 제한이 없다. 상기 수산화알루미늄 및 수산화마그네슘 중 1종 이상은 2~70중량부 사용되는 것이 바람직한데, 사용량이 2중량부 미만인 경우에는 화염 방지효과가 미미하여 바람직하지 않고, 70중량부를 초과하는 경우에는 장식시트의 면상태가 균일하지 않기 때문에 바람직하지 않다.In the aluminum hydroxide used in the present invention, the hydrate absorbs heat during the exothermic process, and the aluminum oxide generated in the oxidation process of the aluminum hydroxide exhibits a low smoke effect. It is possible to substitute the same amount of magnesium hydroxide with similar properties instead of aluminum hydroxide, or it is also possible to use a mixture of aluminum hydroxide and magnesium hydroxide, there is no particular limitation on the mixing ratio. At least one of the aluminum hydroxide and magnesium hydroxide is preferably used 2 to 70 parts by weight, if the amount is less than 2 parts by weight, the effect of preventing flame is insignificant, and if it exceeds 70 parts by weight, the surface of the decorative sheet It is not preferable because the state is not uniform.

본 발명의 난연제 조성물에는 상기 성분들 이외에 삼산화안티몬을 첨가할 수 있는데, 상기 삼산화안티몬은 화염전파 성능이 우수하지만 연기발생을 증가시키는 특징을 갖고 있으므로, 적용시 1~10중량부를 적용하여 방염성능을 일부 증가시킬 수 있다.Antimony trioxide may be added to the flame retardant composition of the present invention in addition to the above components. The antimony trioxide has excellent flame propagation performance but has a feature of increasing smoke generation. You can increase some.

본 발명에 따른 난연제 조성물은 상기 성분들을 배합한 후 교반기를 통해 적절히 혼련하므로써 제조될 수 있다. 본 발명의 난연제 조성물을 이용하여 장식시트를 제조한 예로서, 폴리비닐클로라이드(PVC) 수지 100중량부, 가소제 5~30중량부, 안정제 2~4중량부, 난연제 조성물 10~40중량부를 배합하여 제조되는 PVC 시트를 들 수 있다. 이때 난연제 조성물의 사용량이 10중량부 미만인 경우에는 방염성능을 나타내지 못하며, 40중량부를 초과하는 경우에는 PVC 시트의 기계적 물성을 악화시켜 바람직하지 않다.The flame retardant composition according to the present invention may be prepared by blending the above components and then kneading properly through a stirrer. As an example of manufacturing a decorative sheet using the flame retardant composition of the present invention, 100 parts by weight of polyvinyl chloride (PVC) resin, 5 to 30 parts by weight of plasticizer, 2 to 4 parts by weight of stabilizer, 10 to 40 parts by weight of flame retardant composition The PVC sheet manufactured is mentioned. In this case, when the amount of the flame retardant composition is less than 10 parts by weight, it does not exhibit flame retardant performance, and when it exceeds 40 parts by weight, it is not preferable to deteriorate the mechanical properties of the PVC sheet.

상기 난연제 조성물은 과립화하여 사용하는 것이 바람직하며, 이때 입도는 1~10㎛ 사이가 바람직한데, 입도가 1㎛ 미만인 경우에는 혼련이나 분산이 미흡하게 될 문제가 발생하며, 10㎛를 초과하는 경우에는 PVC 시트의 면을 고르게 제조하기 어렵다.The flame retardant composition is preferably used to granulate, wherein the particle size is preferably between 1 ~ 10㎛, when the particle size is less than 1㎛ problem occurs that the kneading or dispersion is insufficient, if more than 10㎛ It is difficult to evenly produce the sides of the PVC sheet.
