Embodiment Construction

[0017] Below in conjunction with example the present invention is described in further detail.

[0018] Such as figure 1 As shown, the first embodiment of the present invention-the film structure without base material. The conductive heat-sensitive pressure-sensitive adhesive tape includes: a release material layer 1 , and a conductive heat-sensitive adhesive layer 2 is provided on one surface of the release material layer 1 . Wherein, the conductive heat-sensitive adhesive layer 2 is formed by coating acrylic pressure-sensitive adhesive with conductive particles and expanded microspheres uniformly stirred.

[0019] Such as figure 2 As shown, the second embodiment of the present invention---metal foil substrate with adhesive film structure on one side. The structure of this embodiment is substantially the same as that of the first embodiment, except that a conductive metal foil substrate 3 is further provided on the outer surface of the conductive heat-sensitive adhesive l...

Abstract

The invention discloses a conductive heat-sensitive pressure-sensitive adhesive tape. The adhesive tape comprises a release material layer and a conductive heat-sensitive adhesive layer which is arranged on one surface of the release material layer, wherein the conductive heat-sensitive adhesive layer is formed by spreading an adhesive which is formed by adding conductive particles and expanded microspheres into acrylic pressure-sensitive adhesive and uniformly stirring the mixture. The pressure-sensitive adhesive tape has features of good flexibility, self-adhesion of the pressure-sensitive adhesive, low-temperature rapid irreversible blocking, thinner thickness and excellent shielding function, excellent electric conduction performance can be kept at normal temperature, and the tape can expand within 3-6 seconds when the temperature reaches a certain temperature and the blocking can be completed, the expansion compressive strength can be up to 100-200 psi / square inch.

Description

technical field [0001] The invention relates to an adhesive tape, in particular to a conductive heat-sensitive pressure-sensitive adhesive tape with electromagnetic shielding function used in communication equipment, household appliances, industrial equipment, batteries, automotive power equipment and other industries. Background technique [0002] With the rapid development of electronic technology, as an auxiliary material of electronic products - pressure-sensitive tape has also derived many special tape products with different functions with the development of electronic products, such as insulation, shielding, conductivity, heat dissipation, structural bonding, shockproof , protection and other functional products. In today's rapidly developing society, the use of health and safety has been recognized and required by people. How to cut off the power supply of the battery or circuit at high temperature is a fundamental safety issue related to the electronic products of ...
