Abstract
The utility model relates to an adhesive tape, in particular to a glue overflow resistant tearable adhesive tape. The glue overflow resistant tearable adhesive tape sequentially comprises a first acrylic flexible glue layer, a tearable acrylic hard glue layer, a second acrylic flexible glue layer and dual silicon release paper from top to bottom, wherein the first acrylic flexible glue layer, the tearable acrylic hard glue layer and the second acrylic flexible glue layer are tightly adhered into a whole through pressure of coating equipment. The tearable acrylic hard glue is combined with the acrylic flexible glue, the stiffness of the tearable acrylic hard glue and the adhesive strength of the acrylic flexible glue are utilized, and the tearable acrylic hard glue in the middle layer serves as a base material, so that the stiffness of the whole adhesive tape is improved; and moreover, by the flexible acrylic glue on two sides, the adhesive force required by the adhesive tape is increased, the three glue film layers are adhered by the pressure of the coating equipment and are tightly adhered into a whole, so that the adhesive tape is high in adhesive force and glue overflow resistant.
Description
Technical field
The utility model relates to a kind of adhesive tape, a kind of specifically tearable property of glue adhesive tape that do not overflow.
Background technology
For a long time, excessive glue has been regarded as characteristics of the character of adhesive tape own.Every adhesive tape is no matter low sticking or high adhesive tape must have excessive glue problem, especially high adhesive tape.Major cause is readily appreciated that.At first, PSA glue is claimed tamanori again, belongs to soft attitude.After the high bake through baking box (up to 110 ° of C) and maturation chamber (about 60 ° of C～70 ° C) solidified, it still kept its soft kenel.And in general, just glue and stick together the outstanding adhesive tape of performance, texture is soft more partially.Therefore when adhesive tape is under pressure extruding (cutting die for example, punching block, cutting machine, rigging machine, wheel shaft pressure-sensitive etc. even) adhesive tape flexible type phenomenon all can occur, and this also represented the beginning of excessive glue.Moreover the effect of PSA glue itself is exactly bonding, especially when being applied to the electronic product inner part, more highlights its importance; Material of all kinds is desired sticks together dynamics all unequal (being applied to plastic component, ironware, aluminum component etc.), as the dynamics of sticking together causes the layering of electronic product inner part inadequately, all can cause serious bad product rejection even.And if PSA glue adhesion is strong more, its excessive glue problem is serious.But after the problem of weighing stratified risk of inner part and excessive glue, still can be to take the former into account for mainly considering.Therefore, the glue problem of overflowing have to be accepted, but still in the course of processing, causes client terminal much to perplex.
The utility model content
The utility model technical problem to be solved is to the shortcoming that above prior art exists, to propose a kind of tearable property of glue adhesive tape that do not overflow, the glue but adhesion does not overflow by force.
The technical scheme that the utility model solves above technical problem is:
The tearable property of glue adhesive tape does not overflow; Be followed successively by the first acrylic flexible glue layer, tearable property acrylic ebonite layer, the second acrylic flexible glue layer and two silicon separate-type paper from top to bottom, the first acrylic flexible glue layer, tearable property acrylic ebonite layer, the second acrylic flexible glue are become one through coating apparatus pressure applying close adhesion.
The technical scheme that the utility model further limits is:
The aforesaid tearable property of the glue adhesive tape that do not overflow, the thickness of tearable property acrylic ebonite layer is 8～12um.
The aforesaid tearable property of the glue adhesive tape that do not overflow, the thickness of the first acrylic flexible glue layer and the second soft acrylic flexible glue layer is 15～25um.
The utility model has the advantages that: the utility model is done tearable property acrylic ebonite and is combined with the acrylic flexible glue; Get the deflection of tearable property acrylic ebonite and the dynamics of sticking together of acrylic flexible glue; The tearable property acrylic ebonite in middle layer is as as base material, promoting the whole stiffness of adhesive tape; The soft attitude acrylic glue on both sides then promotes the required adhesion of adhesive tape itself; Three layers of glued membrane are after fitting through the pressure of coating apparatus, and close adhesion is become one, but make the excessive by force glue of adhesive tape adhesion.Because there be adding of tearable property glued membrane to hold, make colloid not flexible type also avoided the problem of excessive glue, and on the other hand, through Quality Detection, the two-sided adhesion data that draw are also outstanding, all can reach the standard of 1kg/in.

Embodiment
Present embodiment discloses a kind of tearable property of glue adhesive tape that do not overflow; Be followed successively by the first acrylic flexible glue layer 1, tearable property acrylic ebonite layer 2, the second acrylic flexible glue layer 3 and two silicon separate-type paper 4, the first acrylic flexible glue layers 1, tearable property acrylic ebonite layer 2, the second acrylic flexible glue 3 from top to bottom and become one through coating apparatus pressure applying close adhesion.The thickness of tearable property acrylic ebonite layer is 8～12um.The thickness of the first acrylic flexible glue layer and the second soft acrylic flexible glue layer is 15～25um.
The utility model at first, uses tearable property acrylic ebonite to make the very thin tearable property glued membrane of one deck when concrete production.Then, at first of the tearable property glued membrane soft attitude acrylic glue of coating, be positioned under the normal temperature maturation after coating finishes and wait for that glued membrane interpenetrates with tearable property glued membrane and combine.At last, at second of the tearable property glued membrane soft attitude acrylic glue of coating, equally be positioned under the normal temperature maturation after coating finishes and wait for that glued membrane interpenetrates with tearable property glued membrane and combine.The tearable property glued membrane in middle layer is as promoting the whole stiffness of adhesive tape as base material, the soft attitude acrylic glue on both sides then promotes the required adhesion of adhesive tape itself.Three layers of glued membrane are after fitting through the pressure of coating apparatus, and close adhesion is become one.Through processing test because there be adding of tearable property glued membrane to hold, make colloid not flexible type also avoided the problem of excessive glue, and on the other hand, through Quality Detection, the two-sided adhesion data that draw are also outstanding, all can reach the standard of 1kg/in.
Except that the foregoing description, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
