Description

융착식 도로 표시재료의 용해용 포장재{Packaging bags for road marking materials} Packaging bags for melting of road marking materials

본 발명은 도로표지 재료의 포장재에 관한 것으로, 보다 상세하게는 센터라인(중앙선), 사이드라인(노견선), 횡단보도, 그 외의 도로표지를 시행할 때에 사용되어지는 융착식 재료를 포장하는 포장재에 관한 것이다. The present invention relates to a pavement material for road marking materials, and more particularly, pavement material for packaging fused materials used when applying a center line (center line), a side line (route line), a crosswalk, and other road markings. It is about.

최근, 환경오염 문제가 심각한 가운데 사용이 끝난 물품 및 폐기물의 재이용 또는 처리에 대한 다양한 연구가 지속적으로 행해지고 있다. 도로표시 재료를 포장하는 봉투도 예외는 아닌데, 종래 도로표지 재료의 포장재로 주로 사용되고 있는 것은 폴리에틸렌 포장재이다. 이러한 도로표시 재료를 포장하는 포장재는 사용이 끝난 후에는 그대로 폐기되어 가정에서 나온 일반 쓰레기 등과 함께 소각되는 것이 보통이다. In recent years, various environmental studies have been continuously conducted on the reuse or disposal of used articles and wastes in the midst of serious environmental pollution. Envelopes for paving road marking materials are no exception. Conventionally, polyethylene bags are mainly used as paving materials for road marking materials. Pavements for paving these road marking materials are usually disposed of after use and incinerated with general wastes from households.

폴리에틸렌 포장재를 그대로 융착식 재료의 일부로서 도로 표지재료와 함께 가열 용해하여 이용하는 방법도 있는데, 이 폴리에틸렌 포장재는 폴리에틸렌에 소량의 연화제를 첨가하면, 가소성을 얻을 수가 있고, 또 저온시의 품질 안정성을 도모할 수가 있지만, 이것을 이대로 가열 용융시켜도 융착식 도로표지 재료로서 충분 한 기능을 발휘할 수가 없다. 즉 융착식 도로표지 재료 및 가소제와의 혼합성 및 가열시의 용해점도, 저온 안정성 등에 문제가 있고, 더욱이 가열시에 덩어리가 생기는 등의 문제가 있었다. There is also a method in which the polyethylene pavement is used as it is by heating and dissolving it together with the road marking material as a part of the fusion material. When a small amount of softener is added to the polyethylene pavement, plasticity can be obtained and quality stability at low temperatures can be achieved. Although it can be heated and melted as it is, it cannot fully function as a fusion-type road marking material. In other words, there is a problem in the mixing properties of the fusion-type road marking material and the plasticizer, the melt viscosity at the time of heating, the low temperature stability, and the like, and agglomeration occurs at the time of heating.

따라서, 본 발명의 목적은 별도로 폐기할 필요가 없이 융착식 도로 표시재료와 함께 가열 용융시킬 수 있는 융착식 도로표시 재료의 포장재를 제공하는 것이다. Accordingly, it is an object of the present invention to provide a pavement of a fusion road marking material that can be heated and melted together with the fusion road marking material without the need for disposal.

상기 본 발명의 목적은 비닐아세테이트-에틸렌 공중합체 10~30중량부 및 폴리에틸렌 70~90 중량부를 포함하는 것을 특징으로 하는 도로표시 재료의 포장재에 의해 달성된다. The object of the present invention is achieved by a paving material of a road marking material comprising 10 to 30 parts by weight of vinyl acetate-ethylene copolymer and 70 to 90 parts by weight of polyethylene.

상기 본 발명의 비닐아세테이트-에틸렌 공중합체는 비닐 아세테이트 5~50몰%와 에틸렌 50~95몰%로 구성된 것을 특징으로 한다. The vinyl acetate-ethylene copolymer of the present invention is characterized by consisting of 5 to 50 mol% vinyl acetate and 50 to 95 mol% ethylene.

본 발명의 융착식 도로표시 재료의 포장재는 별도로 폐기할 필요가 없이 융착식 도로 표시재료와 함께 가열 용융시킬 수 있으며, 우수한 물성을 제공한다. The pavement of the fusion road marking material of the present invention can be heated and melted together with the fusion road marking material without needing to be disposed of separately, and provides excellent physical properties.

본 발명의 도로표시 재료의 포장재는 비닐아세테이트-에틸렌 공중합체 10~30중량부 및 폴리에틸렌 70~90 중량부를 포함하는 것을 특징으로 한다. The pavement material of the road marking material of the present invention is characterized in that it comprises 10 to 30 parts by weight of vinyl acetate-ethylene copolymer and 70 to 90 parts by weight of polyethylene.

상기 본 발명의 비닐아세테이트-에틸렌 공중합체는 비닐 아세테이트 5~50몰%와 에틸렌 50~95몰%로 구성된 것을 특징으로 한다. The vinyl acetate-ethylene copolymer of the present invention is characterized by consisting of 5 to 50 mol% vinyl acetate and 50 to 95 mol% ethylene.

폴리에틸렌에 첨가하는 비닐아세테이트-에틸렌 공중합체는 폴리에틸렌을 개 질하여, 융착식 도로표시 재료 및 가소제와의 혼합성과 가열시에 용융점도를 개선하는 역할을 한다. 비닐아세테이트-에틸렌 공중합체를 부가하게 되면 융착식 도로표시 재료와 함께 가열할 때 덩어리 상태가 되는 현상이 없어지게 된다. The vinyl acetate-ethylene copolymer added to polyethylene modifies polyethylene to serve to improve the melt viscosity upon heating and mixing with fusion road marking materials and plasticizers. The addition of vinyl acetate-ethylene copolymer eliminates lumping when heated with fused road marking materials.

본 발명에 사용되는 비닐아세테이트-에틸렌 공중합체는 비닐아세테이트-에틸렌 공중합체는 비닐 아세테이트 5~50몰%와 에틸렌 50~95몰%로 구성되며, 중합도 1000 ~ 1500의 범위의 것이 바람직하다. 비닐 아세테이트 함유량이 지나치게 높은 공중합체는 폴리에틸렌에 첨가하여 포장재를 만드는 경우 성형이 어렵고, 또한 포장재가 서로 밀착해서 개폐를 어렵게 만드는 문제가 있다. 또, 용해가 빠르고, 용해점도가 저하되는 등의 도로표시 재료로서의 모든 물성이 향상되는 이점을 가지고 있지만 포장재로서의 강도가 약해지게 되고, 작업성이 저하되어 하절기에는 사용이 어려운 상태가 된다. 이에 반해, 비닐 아세테이트 함유량이 지나치게 적은 범위에서는 전술한 포장재를 융착식 도로표시 재료와 가열용융시킬 때에 용융에 시간이 오래 걸리고, 유동성이 떨어지며 포장재가 덩어리가 상태가 되는 등, 발명의 목적을 달성하기 어렵게 된다. 비닐 아세테이트: 에틸렌 = 10:90(몰비), 중합도 1200 정도가 가장 바람직하다.In the vinyl acetate-ethylene copolymer used in the present invention, the vinyl acetate-ethylene copolymer is composed of 5 to 50 mol% vinyl acetate and 50 to 95 mol% ethylene, and preferably has a polymerization degree in the range of 1000 to 1500. Copolymer having a high vinyl acetate content is difficult to mold when added to polyethylene to make a packaging material, and also the packaging material is in close contact with each other, making it difficult to open and close. Moreover, although all the physical properties as road marking materials, such as rapid melt | dissolution and a melt viscosity fall, have the advantage that it improves, the strength as a pavement material becomes weak, workability falls, and it becomes difficult to use in summer. On the contrary, in the case where the vinyl acetate content is too low, the above-mentioned paving material is melted for a long time when it is melted with the fusion-type road marking material, the fluidity is poor, and the paving material becomes lumped. Becomes difficult. Vinyl acetate: ethylene = 10:90 (molar ratio) and about 1200 degree of polymerization are the most preferable.

본 발명의 포장재에는 전체 중량의 1~5% 정도의 대전방지제 등의 첨가제를 더 부가할 수 있다.To the packaging material of the present invention, additives such as an antistatic agent of about 1 to 5% of the total weight may be further added.

포장재 필름의 두께는 150 ~ 200㎛ 가 바람직하다. As for the thickness of a packaging film, 150-200 micrometers is preferable.

이하 하기 조성으로 제조한 본 발명의 포장재의 물성을 시험한 결과를 하기 시험에에 나타내었다, The results of testing the physical properties of the packaging material of the present invention prepared by the following composition is shown in the following test,
