Detailed description of the invention
Introduce detailed description of the invention of the present utility model below in conjunction with the accompanying drawings.
As shown in Figure 1; a kind of structure-improved of double faced adhesive tape; the protective layer 1 that the bottom 5 and PET mould release membrance made including the double-sided adhesive layer 3 of a stretchable vanishing viscosity made with easy-to-draw glue, Ge Laxin release paper is made, bottom 5, adhesive layer 3, protective layer 1 are fitted the most successively；The holding sheet 2 that PET mould release membrance is made it is provided with between adhesive layer 3 and bottom 5; relative arranges mutually isostructural holding sheet 2 between adhesive layer 3 with protective layer 1; two holding sheet 2 symmetries are fitted in one end of adhesive layer 3 length direction; the other end of adhesive layer 3 length direction extends outward the wedge angle of 60 degree, and the limit of wedge angle is 30 degree of angles with the length direction of holding sheet 2；With 1/cm between adhesive layer 3 and protective layer 12Density variance distribution hot-melt adhesive granules 6；Wherein the off-type force of bottom 5 is less than the off-type force of protective layer 1, and the off-type force of protective layer 1 is less than the off-type force of holding sheet 2.A functional interlayer 4 it is provided with in adhesive layer 3.
Embodiment one:
As shown in Figure 2 and Figure 3, the double faced adhesive tape of the present embodiment is ribbon, one end laminating holding sheet 2 of adhesive layer 3 length direction, the other end of adhesive layer 3 length direction extends outward the wedge angle of 60 degree, wedge angle is 30 degree of angles with the length direction with holding sheet 2, the heat-conducting layer that interlayer 4 is made for conductive graphite thin film.
nullWhen the double faced adhesive tape of the present embodiment uses，First tear bottom 5，Adhesive layer 3 is attached on first substrate 72，Tear protective layer 1 again，First plate object 71 touched hot-melt adhesive granules 6 before this，The hot-melt adhesive granules 6 viscosity when not melting is relatively low，First plate object 71 can move adjustment position relative to first substrate 72 and adhesive layer 3，Postpone moving to specific bit，Heat to the first plate object 71 or the first plate object 71 with the joint face of first substrate 72 by slight fever sources such as electric-heating air blowers，Hot-melt adhesive granules 6 is heated to the softening temperature of 60-70 degree，Hot-melt adhesive granules 6 soften become plastic or flow regime after under the self gravitation or external force extruding of the first plate object 71, become thin layer PUR 61，First plate object 71 just can be pasted onto on adhesive layer 3，Complete the bonding fastening of the first plate object 71 and first substrate 72.
Internal heat is derived by the interlayer 4 that the first plate object 71 is made by conductive graphite thin film with first substrate 72, helps the first plate object 71 or first substrate 72 to dispel the heat.When the first plate object 71 needs separately with first substrate 72, after thin layer PUR 61 being heated to plastic or flow regime by electric-heating air blower, adhesive layer 3 is driven to stretch by pullling holding sheet 2, after the adhesive layer 3 of stretcher strain loses viscosity, just can thin layer PUR 61, interlayer 4 and adhesive layer 3 be pulled out easily, the first plate object 71 just can separate with first substrate 72.When adhesive layer 3 is stretched to the position of wedge angle, if adhesive layer 3 uses rectangular shape, last straight flange can be entered to middle concave when by concentrating on middle tensile force, after being easily trapped at the two of straight flange angles during disengaging, and 60 degree of horn structure of the present utility model can deform the surface departing from upper and lower object easily.
Embodiment two:
As shown in Figure 4, Figure 5, the double faced adhesive tape of the present embodiment is rectangle lamellar, one end laminating holding sheet 2 of adhesive layer 3 length direction, the other end of adhesive layer 3 length direction extends outward three connected 60 degree wedge angles, the limit of wedge angle is 30 degree of angles with the length direction of holding sheet 2, the electro-magnetic screen layer that interlayer 4 is made for electromagnetic wave shield film.
nullWhen the double faced adhesive tape of the present embodiment uses，First tear bottom 5，Adhesive layer 3 is attached on second substrate 82，Tear protective layer 1 again，The Second Board object 81 touched hot-melt adhesive granules 6 before this，The hot-melt adhesive granules 6 viscosity when not melting is relatively low，The Second Board object 81 can move adjustment position relative to second substrate 82 and adhesive layer 3，Postpone moving to specific bit，Heated to the joint face of the Second Board object 81 or the Second Board object 81 and second substrate 82 by slight fever sources such as electric-heating air blowers，Hot-melt adhesive granules 6 is heated to the softening temperature of 60-70 degree，After hot-melt adhesive granules 6 softens and becomes plastic or flow regime，Thin layer PUR 61 is become under the self gravitation or external force extruding of the Second Board object 81，The Second Board object 81 just can be pasted onto on adhesive layer 3，Complete the bonding fastening of the Second Board object 81 and second substrate 82.
The interlayer 4 that the electromagnetic signal that second substrate 82 produces is made by electromagnetic wave shield film is isolated without being delivered on the Second Board object 81, and the relative electromagnetic signal in the Second Board object 81 generation is not transferred on second substrate 82.When the Second Board object 81 needs separately with second substrate 82, after thin layer PUR 61 being heated to plastic or flow regime by electric-heating air blower, adhesive layer 3 is driven to stretch by pullling holding sheet 2, after the adhesive layer 3 of stretcher strain loses viscosity, just can easily thin layer PUR 61, interlayer 4 and adhesive layer 3 be pulled out, the Second Board object 81 just can separate with second substrate 82, and 60 degree of horn structure of the present utility model can deform the surface departing from upper and lower object easily, it is to avoid the situation about being trapped in below of corner occurs.
Technical scope of the present utility model is not imposed any restrictions by the above, all according to this utility model technical spirit, any amendment, equivalent variations and the modification being made above embodiment, all still falls within the range of the technical solution of the utility model.
