본 발명은 스마트폰 및 태블릿 피씨용 필름형태의 방열 점착테이프에 관한 것으로, 더욱 상세하게는 톨루엔과 같은 인체유해 용제의 사용을 배제하고 통기성 필름이 적용되기 때문에, 점착성, 방열성 및 내충격성이 우수하다.The present invention relates to a heat-dissipating adhesive tape in the form of a film for smartphones and tablet PCs, and more particularly, it is excellent in adhesiveness, heat dissipation, and impact resistance because a breathable film is applied without the use of a harmful solvent such as toluene. .

현재 전자제품에 적용되는 방열 점착테이프의 개발은 전 세계적으로 소수에 불과하며, 이 또한 기술 개발 진행 중이거나 제품의 성능이 검증단계 수준이 대부분이다. 더욱이 휴대폰 및 태블릿 피씨의 경우 제품의 특성상 요구되는 내충격성, 고점착성을 유지하면서 방열성능을 갖추어야 한다.Currently, there are only a few developments of heat-resistant adhesive tapes applied to electronic products. This is also a technology development or product performance is mostly at the verification stage. Furthermore, cell phones and tablet PCs must have heat dissipation while maintaining the impact resistance and high adhesion required for the characteristics of the product.

이에 부합하기 위해 종래에는 디스플레이용 점착테이프와 방열시트가 각각 적용된 방열테이프가 제조되었는데, 점착테이프와 방열시트를 각각 적용함으로 인해 공정이 복잡하고 까다로울 뿐만 아니라 고비용이 소요되는 문제점이 있었다.In order to meet this, conventionally, a heat dissipation tape to which a pressure-sensitive adhesive tape and a heat dissipation sheet were applied was manufactured.

또한, 디스플레이용 제품의 제조과정에 광범위하게 사용되고 있는 톨루엔의 경우는 발암물질로 규정되었음에도 불구하고, 고분자 합성 과정에서 매우 우수한 성능을 나타내어 용제 등으로 사용되고 있다. 톨루엔의 사용되지 않은 무독성 제품의 경우는 톨루엔을 용제로 사용했을 경우에 비해 물성이 저하되는 문제점이 있어 국내에서는 톨루엔이 지속적으로 사용되고 있다.In addition, toluene, which is widely used in the manufacturing process of display products, has been used as a solvent because it shows very excellent performance in the process of polymer synthesis even though it is defined as a carcinogen. In the case of unused non-toxic products of toluene, there is a problem in that physical properties are lowered compared to when toluene is used as a solvent, and toluene is continuously used in Korea.

그러나, 유럽이나 미국 등과 같은 선진국에서의 전자제품 환경유해물질 사용 규제가 강화됨에 따라, 점착제 기술분야에서도 환경파괴나 인체에 유해성을 고려하여 유해물질이나 환경부하물질을 지정하여 제조, 취급 및 폐기에 이르기까지 규제가 더욱 강화되고 있다.However, as regulations on the use of environmentally harmful substances in electronic products have been tightened in developed countries such as Europe and the United States, in the adhesive technology field, it is necessary to designate hazardous substances or environmentally-affected substances in consideration of environmental destruction or harmful effects to the human body to manufacture, handle and dispose of them. Regulations are being tightened further.

그러나 국내에서는 환경규제가 본격적으로 적용되지 않고 있어 의료 분야를 제외한 일반 산업용 점착제의 경우 친환경 제품에 대한 연구가 미비하여 대책이 전무한 실정이다.
However, in Korea, environmental regulations have not been applied in earnest, so in the case of general industrial adhesives except the medical field, research on eco-friendly products is insufficient.

본 발명의 목적은 제조공정이 단순하고, 제조비용이 저렴하면서도 점착성, 방열성 및 내충격성이 우수한 스마트폰 및 태블릿 피씨용 필름형태의 방열 점착테이프를 제공하는 것이다.An object of the present invention is to provide a heat dissipation adhesive tape in the form of a film for smartphones and tablets having a simple manufacturing process, low manufacturing cost and excellent adhesiveness, heat dissipation and impact resistance.

Hereinafter, preferred embodiments of the present invention and physical properties of the respective components will be described in detail with reference to the accompanying drawings. However, the present invention is not limited thereto, And this does not mean that the technical idea and scope of the present invention are limited.

본 발명에 따른 스마트폰 및 태블릿 피씨용 필름형태의 방열 점착테이프는 통기성 필름층(10) 및 상기 통기성 필름층(10)의 상부면 및 하부면에 형성되는 점착층(20)으로 이루어진다.
The heat-resistant adhesive tape in the form of a film for smartphones and tablet PCs according to the present invention comprises a breathable film layer 10 and a pressure-sensitive adhesive layer 20 formed on the upper and lower surfaces of the breathable film layer 10.

상기 통기성 필름층(10)은 본 발명에 따른 스마트폰 및 태블릿 피씨용 필름형태의 방열 점착테이프의 형상을 유지시켜주며, 내충격성을 부여하는 역할을 하는데, 폴리올레핀계로 이루어지며, 특히, 폴리에틸렌 또는 폴리프로필렌으로 이루어지는 것이 바람직하다.The breathable film layer 10 maintains the shape of the heat-resistant adhesive tape in the form of film for smartphones and tablet PCs according to the present invention, serves to impart impact resistance, made of a polyolefin, in particular, polyethylene or poly It is preferably made of propylene.

또한, 상기 통기성 필름층(10)은 3 내지 300 마이크로미터의 두께로 적용가능하나, 10 내지 150 마이크로미터의 두께로 형성될 때, 가장 우수한 형상유지성과 내충격성을 나타낸다.In addition, the breathable film layer 10 is applicable to a thickness of 3 to 300 micrometers, but when formed to a thickness of 10 to 150 micrometers, it exhibits the best shape retention and impact resistance.

또한, 상기 통기성 필름층은 폴리에틸렌 수지를 필름형태로 용융 성형하고, 핀치 롤(PINCH ROLL) 공정을 통해 10 내지 150㎛ 두께로 형성되며, 직경이 0.1 내지 2mm의 관통홀(30)이 형성하는데, 관통홀(30) 사이에 간격은 1 내지 40mm로 유지된다.In addition, the breathable film layer is melt-molded polyethylene resin in the form of a film, and is formed to a thickness of 10 to 150㎛ through a pinch roll (PINCH ROLL) process, the through hole 30 having a diameter of 0.1 to 2mm is formed, The gap between the through holes 30 is maintained at 1 to 40 mm.

전술한 과정을 통해 제조된 통기성필름층(10)은 10 내지 104cc/cm2/sec의 통기성을 가지게 되며, 통기성필름층(10)에 형성된 관통홀(30)로 인해 방열효과가 향상된 스마트폰 및 태블릿 피씨용 필름형태의 방열 점착테이프가 제공된다.
The breathable film layer 10 prepared through the above process has a breathability of 10 to 10 4 cc / cm 2 / sec, smart heat radiation effect is improved due to the through-hole 30 formed in the breathable film layer 10 Provided is a heat-resistant adhesive tape in the form of a film for phones and tablet PCs.

상기 점착층(20)은 상기 통기성필름층(10)의 상부면 및 하부면에 형성되는데, 아크릴계 점착제 100 중량부, 용제 40 내지 100 중량부 및 무기물 10 내지 100 중량부로 이루어지는 것이 바람직하다.The adhesive layer 20 is formed on the upper and lower surfaces of the breathable film layer 10, it is preferably made of 100 parts by weight of the acrylic pressure-sensitive adhesive, 40 to 100 parts by weight of the solvent and 10 to 100 parts by weight of the inorganic material.

상기 아크릴계 점착제는 100 중량부가 첨가되며, 아크릴계 점착제 100 중량부 대비 카르복실기나 히드록실기를 갖는 아크릴계 단량체가 1.1 내지 11 중량부 함유되어 이루어진다.100 parts by weight of the acrylic pressure-sensitive adhesive is added, and 1.1 to 11 parts by weight of the acrylic monomer having a carboxyl group or a hydroxyl group is contained relative to 100 parts by weight of the acrylic pressure-sensitive adhesive.

아크릴계 점착제의 상용성에 영향을 미치는 가장 중요한 인자는 극성도와 분산성을 꼽을 수 있는데, 극성도는 합성시 카르복시기나 히드록실기를 갖는 단량체를 이용하여 공중합함으로서 아크릴계 점착제의 극성도를 조절할 수 있다.The most important factors affecting the compatibility of the acrylic pressure-sensitive adhesive may be the polarity and dispersibility, the polarity can be adjusted by copolymerizing the monomer using a monomer having a carboxyl group or hydroxyl group in the synthesis.

카르복실기나 히드록실기를 갖는 아크릴계 단량체는 전체 아크릴계 점착제 100 중량부 대비 0.1 내지 50 중량부 첨가 가능하나, 1.1 내지 11 중량부의 범위에서 가장 우수한 성능을 보여준다. The acrylic monomer having a carboxyl group or a hydroxyl group may be added in an amount of 0.1 to 50 parts by weight based on 100 parts by weight of the total acrylic pressure sensitive adhesive, but shows the best performance in the range of 1.1 to 11 parts by weight.

카르복실기나 히드록실기를 갖는 아크릴계 단량체의 함량이 11 중량부 이상일 경우에는, 점착층의 상용성과 분산성은 향상되나, 점착력이 저하된다.When the content of the acrylic monomer having a carboxyl group or hydroxyl group is 11 parts by weight or more, the compatibility and dispersibility of the pressure-sensitive adhesive layer is improved, but the adhesive force is lowered.

이때, 상기 카르복실기를 갖는 아크릴계 단량체로는 아크릴산 또는 메타아크릴산 등을 사용하는 것이 바람직하며, 상기 히드록실기를 갖는 아크릴계 단량체로는 히드록시에틸메타아크릴레이트, 히드록시프로필아크릴레이트 및 히드록시부틸아크릴레이트로 이루어진 그룹으로부터 선택된 하나를 사용하는 것이 바람직하다.At this time, it is preferable to use acrylic acid or methacrylic acid as the acrylic monomer having the carboxyl group, and as the acrylic monomer having the hydroxyl group, hydroxyethyl methacrylate, hydroxypropyl acrylate and hydroxybutyl acrylate. It is preferred to use one selected from the group consisting of:

상기와 같은 아크릴 단량체가 사용된 점착층(20)은 다분산 지수(PDI, Poly Dispersity Index)가 5 내지 12를 나타내는데, 이는 상기와 같이 아크릴 단량체가 사용된 아크릴 점착제가 무기물이나 용제와 혼합됐을 때, 상용성을 증가시키기 위하여 통상정으로 사용되는 아크릴 점착제 보다 분산도를 크게 향상시킨 것이다.The adhesive layer 20 using the acrylic monomer as described above has a polydispersity index (PDI) of 5 to 12, which is when the acrylic adhesive using the acrylic monomer is mixed with an inorganic material or a solvent as described above. In order to increase the compatibility, the dispersion degree is greatly improved than the acrylic pressure-sensitive adhesive commonly used.
