Problems solved by technology

[0003] At present, the heat dissipation tapes used for consumer electronic products on the market do not have high heat dissipation efficiency and have no flame-retardant function. In the narrow space of electronic products, once the electronic components short-circuit and catch fire, it will burn nearby electronic components and even burn the whole electronics

Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0016] exist figure 1 Middle: flame retardant layer 1, base material 2, fire extinguishing agent 3, interlayer film 4, adhesive layer 5, heat conducting sheet 6, heat dissipation hole 7.

[0017] Such as figure 1 As shown, a heat-dissipating flame-retardant adhesive tape is provided with a flame-retardant layer 1, a substrate 2, an interlayer film 4 and an adhesive layer 5 sequentially from top to bottom. Substrate 2 is one of copper foil, silver foil and aluminum foil. The thermal conductivity of copper is 401W / mK, the thermal conductivity of aluminum is 237W / mK, and the thermal conductivity of silver is 420W / mK. High-e...

Abstract

The invention discloses a heat-dissipating and flame-retardant adhesive tape, which comprises a base material, a heat conduction sheet bonded to the lower surface of the base material at equal intervals parallel to the length direction of the base material, an interlayer film pasted on the lower surface of the heat conduction sheet and coated on the insulation film. An adhesive layer on the lower surface of the film, a flame retardant layer bonded to the upper surface of the substrate, and a fire extinguishing agent filled between the heat conducting sheets. The invention has high heat dissipation efficiency, can effectively flame retard and extinguish flames, avoids damage to other components when the electronic components are short-circuited and catches fire, and can also prevent the external fire source of the adhesive tape from directly burning the electronic components.

Description

technical field [0001] The invention relates to an adhesive tape, in particular to a heat-dissipating and flame-retardant adhesive tape. Background technique [0002] At present, consumer electronic products such as mobile phones and tablet computers are showing a trend of thinning and performance enhancement. Lighter and thinner means that electronic devices inside electronic products are arranged more and more compactly, and the spare space is getting smaller and smaller, while performance enhancement means that the computing power of processor chips is getting higher and higher, and the capacity of lithium batteries is getting higher and higher. , resulting in increasing heat generation. Changes in these two aspects have put forward higher requirements for current heat dissipation materials. [0003] At present, the heat dissipation tapes used for consumer electronic products on the market do not have high heat dissipation efficiency and have no flame-retardant function...
