본 발명은 고신율 모듈러스 필름 코팅액 및 그를 이용한 고신율 필름의 제조방법에 관한 것으로서, 더욱 구체적으로는 관능기 수가 2인 알리파틱 우레탄 아크릴레이트(Aliphatic urethane Acrylate)인 아크릴계 올리고머, 모노머 및 개시제를 포함하는 탄성을 가진 신율 필름의 코팅액상의 조성 및 함량의 최적화하여 시장에 요구하는 파단강도, 300% 및 600%대의 신율 및 복원속도를 맞춤형을 제공 가능한 고신율 모듈러스 필름 코팅액 및 그를 이용한 고신율 필름의 제조방법에 관한 것이다.The present invention relates to a high elongation modulus film coating solution and a method for manufacturing a high elongation film using the same, and more particularly, to an acrylic oligomer having 2 functional groups and an acrylic oligomer, a monomer and an initiator. The high elongation modulus film coating solution capable of providing customized breaking strength, 300% and 600% elongation and recovery speed required by the market by optimizing the composition and content of the coating liquid phase of the elongation film with it's about
현재 시장에서 신율 필름으로 활용되는 것으로 PPF (Paint Protection Film) 필름 또는 EPU((Elastic Poly Urethane) 필름이 있다. Currently, PPF (Paint Protection Film) films or EPU (Elastic Poly Urethane) films are used as elongation films in the market.
PPF 필름은 우리나라에 도입된 지 10년 정도되지 않는 필름으로서 외부의 각종 미세한 충격으로부터 자동차의 도장을 보호하는 필름이며, 날카로운 칼이 아닌 이상 차키로 긁어도 차량의 도장면을 보호할 수 있다. 즉, 수세미로 온 힘을 다해 비벼도 도장면에는 손상을 단 0.1% 도 주지 않으므로, 날카로운 칼이 아닌 이상 PPF 필름을 뚫는 것은 절대 쉬운 일 아니기 때문에, 페인트면은 완벽하게 보호할 수 있다. PPF film is a film that has been introduced in Korea for less than 10 years. It is a film that protects the paintwork of automobiles from various external shocks. In other words, even if you rub with all your might with a scrubber, it does not damage the painted surface even by 0.1%, so it is never easy to pierce the PPF film unless you have a sharp knife, so you can perfectly protect the painted surface.
또한, PPF 필름 자체의 재질에서 나오는 투명도가 페인트에 뿌리는 스프레이 방식의 클리어보다 광도가 떨어지는 문제가 있고, 시간이 갈수록 자외선에 의해 필름 안쪽의 접착제가 변하여 발생되는 황변 현상도 단점으로 지적된다. In addition, there is a problem that the transparency from the material of the PPF film itself is inferior to the clear spray method sprayed on the paint, and the yellowing phenomenon caused by the change of the adhesive inside the film by ultraviolet rays over time is also pointed out as a disadvantage.
따라서 PPF 필름은 열경화방식의 설비 및 공정비용 고가인 단점이 있어 상용화에는 한계가 있을 뿐 아니라, 시공 이후의 문제점을 개선하기 위하여, 무황변, 발수 기능과 고광택, 오염 방지나 착색 방지 등을 기본적으로 보유하고 있는 내구성의 필름성능이 요구된다.Therefore, PPF film has the disadvantage of high thermal curing equipment and processing cost, so there is a limit to commercialization. Durable film performance possessed by this is required.
관련하여 특허문헌 1은 광경화형 도료 조성물 및 그로부터 형성된 경화코팅층을 포함하는 성형품에 관한 발명을 개시하고 있으며 구체적으로는 5관능기 이상의 다관능성 폴리우레탄 아크릴레이트, 1~2 관능성 폴리우레탄 아크릴레이트, 1~3 관능성 아크릴레이트, 광중합 개시제 및 트리아진계 자외선 흡수제를 포함하고, 플라스틱 기재에 대한 부착성, 내수성, 내습성, 내열성, 내냉열성 등의 물성이 우수하며, 특히 내후성이 우수하여 플라스틱 기재[예컨대, 폴리카보네이트(PC), 폴리메틸메타크릴레이트(PMMA)]용, 특히 자동차 헤드램프(headlamp) 성형품용 광경화형 도료 조성물 및 그로부터 형성된 경화코팅층을 포함하는 성형품을 개시하고 있다. In relation to this, Patent Document 1 discloses an invention related to a molded article including a photocurable coating composition and a cured coating layer formed therefrom, and specifically, polyfunctional polyurethane acrylate with 5 or more functional groups, 1-2 functional polyurethane acrylate, 1 It contains a tri-functional acrylate, a photopolymerization initiator and a triazine-based UV absorber, and has excellent physical properties such as adhesion to plastic substrates, water resistance, moisture resistance, heat resistance, and cold and heat resistance. For example, polycarbonate (PC), polymethyl methacrylate (PMMA)], particularly for automobile headlamp (headlamp) molded article is disclosed a molded article comprising a photocurable coating composition and a cured coating layer formed therefrom.
반면에, EPU 필름은 PPF 대비 저렴하여 현재 대체 가능한 필름으로 진행되고 있다. On the other hand, EPU film is cheaper than PPF, so it is currently being used as an alternative film.
EPU 필름은 일반 폴리우레탄보다 탄성이 첨가된 필름으로서, 높은 투과율로 인한 투명성과 250℃ 고온에도 견딜 수 있는 내열성을 지닌데다 탄성이 뛰어나 구기거나 칼로 그어도 원상태로 돌아올 정도로 복원력이 뛰어나다. 따라서 곡면에도 쉽게 적용할 수 있어 엣지폰도 액정 전체를 커버할 수 있다.EPU film is a film with added elasticity than general polyurethane. It has transparency due to high transmittance and heat resistance that can withstand high temperature of 250℃. It also has excellent elasticity, so that it returns to its original state even when crumpled or cut with a knife. Therefore, it can be easily applied to curved surfaces, and even edge phones can cover the entire liquid crystal.
따라서, EPU 필름은 차량 차체를 보호하는 PPF를 대체하거나, 태블릿 PC와 노트북 내부 빛을 차단하므로 휴대폰용 또는 OLED 봉지용 필름으로도 다양한 분야에 확대 적용될 수 있다. Therefore, the EPU film replaces the PPF that protects the vehicle body or blocks the light inside the tablet PC and laptop, so it can be expanded and applied to various fields as a film for cell phones or OLED encapsulation.
특히, PPF 필름 및 EPU 필름은 고객이 원하는 사이즈, 두께, 특성, 고투과도에 맞게 커스커마이징 제품으로 제공되어야 한다. In particular, the PPF film and the EPU film should be provided as customized products according to the size, thickness, characteristics, and high transmittance desired by the customer.
그러나, PPF 필름 및 EPU 필름 모두 신율과 복원성이 있으나 복원 시간이 느린 문제가 있다. However, although both the PPF film and the EPU film have elongation and recovery, there is a problem in that the recovery time is slow.

It is also called an oligomer because it changes with it.

In addition, curing on the surface is hindered by polymerization by oxygen in the air. In order to reduce the effect of inhibiting polymerization, it is preferable to use a monomer having a reactive group such as an alkyl group, an unsaturated higher fatty acid group, a tetrahydrofurfulyl group, or a benzoyl ether group.

따라서 본 발명의 실시예에 따른 코팅액에 사용되는 모노머는 경화속도도 양호하고 신율 개선에도 영향을 줄 수 있는 혼합모노머가 바람직하고, 더욱 바람직하게는 경화향상성 모노머 10 내지 90중량% 및 신율향상성 모노머 10 내지 90중량%가 혼합된 것이며, 실시예에서는 NVP (N-vinyl-2-pyrrolidone) 35∼65중량%, THFA (Tetrahydrofurfuryl acrylate) 30∼55중량% 및 HEA (2-hydroxyethyl acrylate) 5∼10중량%로 이루어진 혼합모노머를 사용하는 것이다. Therefore, the monomer used in the coating solution according to the embodiment of the present invention is preferably a mixed monomer that has a good curing rate and can also affect elongation improvement, more preferably 10 to 90% by weight of the curing improving monomer and elongation improving property 10 to 90% by weight of the monomer is mixed, and in the example, 35 to 65% by weight of NVP (N-vinyl-2-pyrrolidone), 30 to 55% by weight of THFA (Tetrahydrofurfuryl acrylate), and 5 to HEA (2-hydroxyethyl acrylate) It is to use a mixed monomer consisting of 10% by weight.

Depending on the type of resin, the photoinitiator is contained in an amount of 1 to 10%, and the monomers, oligomers, and free groups apply the energy required for photopolymerization to initiate photopolymerization so that these materials are converted into a polymer material after curing.

The punched sample was cured after irradiating the sample with light to prepare a film.
상기 타발된 시료를 가로×세로×두께(10mm×10mm×100um)로 제단하고, 측정 센티자 위에 한쪽 면 고정 반대면 분당 300mm/min 속도로 당겨, 필름 끊어질 때(파단) 길이(mm)를 확인하였다. Cut the punched sample in width×length×thickness (10mm×10mm×100um), fix one side on the measuring centimeter, and pull the other side at a speed of 300mm/min per minute, when the film breaks (breaking) length (mm) Confirmed.
파단점 확인되면 그 측정값 -0.2mm까지 늘렸다 반대고정부위 풀어 돌아오는 시간(sec)을 확인하였다.When the break point was confirmed, the measured value was increased to -0.2 mm, and the time (sec) to return the opposite fixing part was checked.
원 제단사이즈 10mm의 90% 돌아 왔을 때 측정시간 기입하고, 단, 돌아오지 않는 경우 1분 방치 후 돌아온 길이 값 기입하여 물성을 기재하였다.When 90% of the original altar size of 10mm returned, the measurement time was written. However, if it did not return, the length value returned after leaving it for 1 minute was written to describe the physical properties.
실험 결과에 있어서 개시제에 따른 신율 필름의 물성 영향평가를 나타내면 표 1과 같다.Table 1 shows the effect evaluation of the physical properties of the elongation film according to the initiator in the experimental results.
상기 표 1의 결과로부터, 모노머와 올리고머 반응성에 따라 개시제는 1-하이드로-사이클로헥실-페닐-케톤(I-184), 포스핀 옥사이드, 페닐 비스 (2, 4, 6-트리메틸벤조일)(I-819), 2-하이드록시-2-메틸-1-페닐-1-프로판온(I-1173) 및 디페닐 (2, 4, 6-트리메틸벤조일)-포스핀옥사이드(TPO) 중에서 선택된 개시제를 사용할 수 있다.From the results of Table 1, according to the monomer and oligomer reactivity, the initiator is 1-hydro-cyclohexyl-phenyl-ketone (I-184), phosphine oxide, phenyl bis (2, 4, 6-trimethylbenzoyl) (I- 819), 2-hydroxy-2-methyl-1-phenyl-1-propanone (I-1173) and diphenyl (2, 4, 6-trimethylbenzoyl)-phosphine oxide (TPO) can

From the results of Table 3, it was confirmed that the elongation and elastic properties greatly changed according to the selection of the oligomer.
