Abstract

Provided is a double-sided adhesive tape which exhibits favorable adhesive strength with an object subject to adhesion while having a thin width of the tape and has a remarkable waterproof function. The double-sided adhesive tape is in a form of a film which is constituted of a film material with a minimum thickness and is prepared by combining a non-foaming substrate (TPO/TPU/PVA) with both sides of PI/PET/PEN having a thickness of 50 to 100 μm. In the present invention, a problem of a conventional technology is alleviated by providing the waterproof double-sided adhesive tape having excellent impact resistance and impact absorptivity without degrading waterproofing property in the case of narrowing the with of the tape. Therefore, the multipurpose double-sided adhesive tape of the present invention can adhere to the substrate by self-adhesion and can minimize height difference with the surface of the substrate and height difference with a joint by having a thin thickness, while providing remarkable waterproofing property to the connection joint.

These electronic devices are required to continuously develop technologies for thinning, lightening, low power consumption, high resolution, and high brightness.

본 발명은 스마트폰 및 태블릿 피씨용 필름형태의 방수 점착테이프에 관한 것으로, 더욱 상세하게는 지존 기지 필름 위에 탄성을 지는 비발포체를 합지하고 양면 점착 처리 하여 점착성, 방수성 및 내충격성이 우수하다.The present invention relates to a waterproof adhesive tape in the form of a film for a smartphone and a tablet PC. More particularly, the present invention relates to a waterproof adhesive tape in the form of a film for a smartphone and a tablet PC.

현재 전자제품에 적용되는 방수 점착테이프의 개발은 전 세계적으로 소수에 불과하다. 더욱이 휴대폰 및 태블릿 피씨의 경우 제품의 특성상 요구되는 내충격성, 고점착성을 유지하면서 방수성능을 갖추어야 한다.Currently, the development of waterproof adhesive tapes applied to electronic products is only a few in the world. Furthermore, in the case of mobile phones and tablet PCs, waterproof performance must be maintained while maintaining the required impact resistance and high tackiness due to the characteristics of the product.

이에 부합하기 위해 종래에는 디스플레이용 점착테이프와 발포체가 각각 적용된 방수테이프가 제조되었는데 발포체의 두께가 높아 제품의 소형, 슬림화에 한계를 가지고 있다.
To cope with this problem, a waterproof tape using a pressure-sensitive adhesive tape for display and a foam has been conventionally manufactured, but the thickness of the foam is so high that it is limited in size and slimness of the product.

본 발명의 목적은 제조공정이 단순하고, 제조비용이 저렴하면서도 점착성, 방수성 및 내충격성이 우수한 스마트폰 및 태블릿 피씨용 필름형태의 방수 점착테이프를 제공하는 것이다.An object of the present invention is to provide a waterproof adhesive tape in the form of a film for a smartphone and a tablet PC having a simple manufacturing process and a low manufacturing cost, but also excellent adhesiveness, waterproofness and impact resistance.

본 발명의 다른 목적은 기존의 사용되어 지고 있는 발포성 원단에 비해 기재의 두께를 최소화하여 제품의 소형, 슬림화를 할 수 있는 필름형태의 방수 점착테이프를 제공하는 것이다.Another object of the present invention is to provide a film-type waterproof adhesive tape capable of minimizing the thickness of a base material and making it smaller and slimmer than existing foamable fabric used.

본 발명의 목적을 달성하기 위하여 본 발명의 양면 점착 테이프는 비발포체 기재 및 아크릴계 수지를 포함하는 점착층을 포함하고, 상기 점착층은 상기 비발포체 기재의 양면에 형성된 것을 특징으로 하는 스마트폰 및 태블릿 피씨용 필름형태의 방열 점착테이프를 제공함에 의해 달성된다.
In order to achieve the object of the present invention, the double-sided adhesive tape of the present invention comprises a non-foam substrate and an adhesive layer comprising an acrylic resin, and the adhesive layer is formed on both sides of the non-foam substrate. A heat-sensitive adhesive tape in the form of a film for a PC is provided.
