【発明の詳細な説明】
本発明は熱伝導性の良好な粘着テープに関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an adhesive tape with good thermal conductivity.
従来から紙、布、プツヌチックフイルム、金属箔などの
片面に感圧性接着剤全塗工した粘着テープ、粘着シート
が包装材料、防蝕材料、電気絶縁材料など広範凹の用途
に使用されている。Adhesive tapes and sheets, which are fully coated with pressure-sensitive adhesive on one side of paper, cloth, plastic film, metal foil, etc., have been used for a wide range of applications such as packaging materials, corrosion-resistant materials, and electrical insulation materials. .
これは粘着テープ、粘着シートが多種類の被着材に接触
させるだけで簡単に接着し、被着材に永久的に強固に接
着するか、或は被着材に接着剤食残さずに剥離すること
が出来るという使用上の便利性に拠るところが大きい。This adhesive tape or adhesive sheet easily adheres to various types of adherends simply by contacting them, permanently and firmly adheres to the adherends, or peels off without leaving any adhesive residue on the adherends. This is largely due to the convenience of use.

求されるようになつ九。However, in recent years, due to the diversification of people's needs, the rise of luxury products, and the increasing constraints on resources and energy, adhesive tapes and adhesive sheets have come to be required to have various characteristics in addition to their original convenience9.

ある。 この種のテープではアルミニウム箔の熱伝導度
は大きいので感圧性接着剤の熱伝導度の大小がテープの
熱伝導性の棗否金決定することになる。As one of these, there is a high demand for adhesive tapes and adhesive sheets, which have traditionally been used as insulators, to be used as conductors of heat and electricity. For example, the aluminum foil adhesive tape used for adhering the heat dissipation pipes of energy-saving electric refrigerators must have as high a thermal conductivity as possible. In this type of tape, the aluminum foil has a high thermal conductivity, so the thermal conductivity of the pressure sensitive adhesive determines the thermal conductivity of the tape.

の一程度といえる。Metal foil generally has high thermal conductivity, and in addition to aluminum foil, gold foil and iron foil can be used as base materials for adhesive tapes. In addition, pressure-sensitive adhesives are manufactured from natural rubber, synthetic rubber, polyacrylic acid ester, etc., but all of them are polymeric materials, and the thermal conductivity of polymeric materials varies slightly depending on the type. It also varies depending on the degree of crosslinking in the adhesive, the presence or absence of air bubbles, etc., but it can generally be said to be about one-hundredth of that of metal.

とが出来たのである。The inventor of the present invention focused on the large difference in conductivity between metals and polymeric substances, and attempted to combine the two.As a result, the inventors were able to uniformly contain metal powder in a pressure-sensitive adhesive. This made it possible to create a pressure-sensitive adhesive with high electrical conductivity. Furthermore, by applying a coating layer of this pressure-sensitive adhesive to one or both sides of the metal foil, it was possible to create adhesive tapes and adhesive sheets with good thermal conductivity. .

That is, if the amount added is less than the minimum amount, no improvement in conductivity can be obtained, and if the amount added is more than the maximum amount, the inherent adhesive properties of the pressure-sensitive adhesive cannot be exhibited.
