Description
본 발명은, 점착 테이프에 관한 것이다.The present invention relates to an adhesive tape.
일렉트로닉스 기술의 현격한 진보에 의해 전기, 전자, OA 기기가 고집적화·고성능화되고, 그들 기기의 내부에서의 고온화나 축열에 의한 발화의 위험성을 저감 내지 발화를 방지하기 위해, 상기 기기에 이용되는 점착 테이프에 있어서도 높은 난연성이 요구되고 있다. 또, 가전, 차량, 건재 등의 각 분야에서도 플라스틱 재료의 난연화에 대해 다양한 연구가 이루어지고 있고, 그들의 고정에 이용되는 점착 테이프에도 마찬가지로 높은 난연성이 요구되고 있다.Electrical, electronic, and OA devices have become highly integrated and high-performance due to remarkable advances in electronics technology, and in order to reduce or prevent the risk of ignition due to high temperature or heat storage inside those devices, the adhesive tape used in the devices Also, high flame retardancy is required. In addition, various studies have been made on flame retardancy of plastic materials in each field such as home appliances, vehicles, and building materials, and high flame retardancy is similarly required for adhesive tapes used for fixing them.
그리고, 그러한 점착 테이프로서는, 예를 들면 특허문헌 1에 나타내어지는 기술이 제안되어 있고, 이 기술에 의하면, 양호한 난연 특성과 점착 특성을 겸비할 수 있게 되어 있다.And as such an adhesive tape, the technique shown, for example by patent document 1 is proposed, and according to this technique, it becomes possible to have both favorable flame retardance characteristic and adhesive characteristic.
그러나, 근년에는, 예를 들면 상기의 용도에 있어서 가일층의 고집적화, 경량화가 진행되어, 점착 테이프에 있어서는, 종래의 점착 테이프보다 높은 난연성뿐만 아니라, 가일층의 박육화도 요구되고 있다. 점착 테이프를 박육화하기 위해서는, 점착 테이프의 기재뿐만 아니라, 점착제층의 박육화가 필요하게 된다. 그러나, 점착 테이프는 박육화할수록 테이프 체적에 대한 공기 접촉 면적의 비율이 커지기 때문에, 일반적으로 연소되기 쉬워진다. 따라서, 박육화와 난연성을 양립시킨 점착 테이프를 제공하려면, 종래보다 높은 난연 설계가 요구된다.However, in recent years, for example, in the said use, further high integration and weight reduction advance, in the adhesive tape, not only the flame retardance higher than the conventional adhesive tape, but also thickness reduction is calculated|required further. In order to reduce the thickness of the pressure-sensitive adhesive tape, it is necessary to reduce the thickness of the pressure-sensitive adhesive layer as well as the base material of the pressure-sensitive adhesive tape. However, since the ratio of the air contact area to the tape volume increases as the thickness of the adhesive tape decreases, it is generally liable to burn. Therefore, in order to provide the adhesive tape which made thickness reduction and flame retardance compatible, a flame-retardant design higher than conventional is calculated|required.
그래서, 본 발명은, 박육화했을 경우여도 점착성 및 난연성을 높은 레벨로 양립하는 것이 가능한 점착 테이프를 제공하는 것을 목적으로 한다.Then, an object of this invention is to provide the adhesive tape which can make adhesiveness and a flame retardance compatible at a high level even if it is a case where thickness reduction is carried out.
본원 발명은 이하와 같다.The present invention is as follows.

여기서, 난연제가 폴리인산암모늄을 함유하는 경우에는, 폴리인산암모늄의 X선 회절 측정에 있어서, 회절각 2θ=15.5±0.2°의 피크 강도값을, 회절각 2θ=14.6±0.2°의 피크 강도값으로 나눈 값(이하, 피크 강도비라고도 칭한다)이, 1.4 이상인 것이 바람직하다.Here, when the flame retardant contains ammonium polyphosphate, in X-ray diffraction measurement of ammonium polyphosphate, the peak intensity value of the diffraction angle 2θ = 15.5 ± 0.2 °, the peak intensity value of the diffraction angle 2θ = 14.6 ± 0.2 ° It is preferable that the value obtained by dividing by (hereinafter also referred to as peak intensity ratio) is 1.4 or more.
폴리인산암모늄은, 그 결정 상태에 따라서 I형, II형이 존재하며, II형의 폴리인산암모늄이 난연성 향상에 효과적이다. 그리고, 폴리인산암모늄의 회절각 2θ=15.5±0.2°에 나타나는 피크는, II형의 폴리인산암모늄에서 특징적으로 관찰되는 피크이고, 또, 회절각 2θ=14.6±0.2°의 피크는, I형, II형의 폴리인산암모늄에서 특징적으로 관찰되는 피크이다. 즉, 상기와 같이 피크 강도비를 규정함으로써, 폴리인산암모늄 중의 II형의 함유량을 규정할 수 있음과 더불어, 폴리인산암모늄 중에 허용되는, 난연성에 대한 기여가 비교적 낮은 I형의 폴리인산암모늄의 함유량을 규정하고 있다. 따라서, 피크 강도비를 상기의 관계로 함으로써, 폴리인산암모늄 중에 존재하는 II형의 폴리인산암모늄의 함유량을 높일 수 있으므로, 점착제층을 박육화한 점착 테이프여도 난연성을 보다 확보할 수 있다.Ammonium polyphosphate exists in I-type and II-type depending on the crystal state, and II-type ammonium polyphosphate is effective in improving the flame retardance. The peak appearing at the diffraction angle 2θ = 15.5 ± 0.2 ° of ammonium polyphosphate is a peak characteristically observed in type II ammonium polyphosphate, and the peak at the diffraction angle 2θ = 14.6 ± 0.2 ° is the type I, It is a peak characteristically observed in type II ammonium polyphosphate. That is, by specifying the peak intensity ratio as described above, the content of type II in ammonium polyphosphate can be defined, and the content of ammonium polyphosphate of type I, which has a relatively low contribution to flame retardancy, is allowed in ammonium polyphosphate. is stipulated Therefore, since content of II-type ammonium polyphosphate which exists in ammonium polyphosphate can be raised by making peak intensity ratio into said relationship, even if it is the adhesive tape which thickness-reduced an adhesive layer, a flame retardance can be ensured more.
또, 본 실시형태에서는, 동일한 관점에서는, 회절각 2θ=15.5±0.2°의 피크 강도값을, 회절각 2θ=14.6±0.2°의 피크 강도값으로 나눈 값이, 1.5 이상인 것이 바람직하고, 보다 바람직하게는 1.6 이상이며, 더 바람직하게는 2.0 이상이다.Further, in the present embodiment, from the same viewpoint, the value obtained by dividing the peak intensity value at the diffraction angle 2θ = 15.5±0.2° by the peak intensity value at the diffraction angle 2θ=14.6±0.2° is preferably 1.5 or more, and more preferably Preferably it is 1.6 or more, More preferably, it is 2.0 or more.

By setting the particle diameter D95 to 20.0 μm or less, the number of particles having a relatively large particle diameter decreases, so even if the flame retardant is not compatible with the adhesive component and exists in the adhesive layer as a solid, the spacer effect caused by relatively large particles is suppressed, and the adhesive Even if it is the adhesive tape which thinned the layer, adhesiveness can be ensured.
또한, 난연제가 복수의 종류의 난연제를 함유하는 경우에는, 복수의 종류의 난연제가 각각, 입자경 D95의 소정의 범위를 만족시키는 것으로 한다.In addition, when a flame retardant contains several types of flame retardants, let the several types of flame retardants satisfy|fill the predetermined range of particle diameter D95, respectively.
