Description
Technical field
This utility model relates to a kind of double faced adhesive tape, particularly to a kind of heat-conducting double-sided adhesive film material.
Background technology
Along with the fast development of electric consumers, the electric consumers such as smart mobile phone, IPAD develops to slimming, portable direction gradually.Adhesion strength owing to being given for the adhesive tape of bonding electronic unit in electronic product industry should be greater than 5N/25mm, in order to meet this requirement, the thickness of the glue of the polyester layer dual coating of traditional polyester two-sided tape is all thicker, thus causing that the general thickness of adhesive tape is also thicker, it is impossible to meet the requirement of electronic product slimming development.
The common two-sided tape thickness sold on the market now is thicker, there is peeling force uneven, the non-differentiation design of off-type force of upper and lower PET mould release membrance, it is easy to cause mould release membrance to separate unsuccessfully, affect sticking operation, processability and workability.And the color of common two-sided tape is single, antistatic effect is poor, heat-conducting effect is undesirable, it is impossible to meet the assembling demand of electronic product.
So prepare a kind of can be applicable to electron trade with coloured, antistatic effect is strong, the ultrathin double-face glue of good heat conduction effect is necessary.
Summary of the invention
The technical problems to be solved in the utility model there is provided a kind of heat-conducting double-sided adhesive film material, the heat-conducting effect of this double faced adhesive tape membrane material is very good, and peeling force is very high, very good with the cohesive force of PET film, and tack is good, affixed object have the height of moment stick together effect.
For solving above-mentioned technical problem, the technical scheme that this utility model adopts is as follows:
A kind of heat-conducting double-sided adhesive film material, including PET film layer, it is characterised in that:
