Abstract

A blended base material adhesive belt comprises double-faced release function mylar or paper, and blended base material coated among the release function mylar or paper, wherein mylar or paper and a double-faced coating release agent are provided, the blended base material is provided with three layers, wherein one sides of the first layer of acryl resin adhesive and the third acryl resin adhesive are respectively adhered to the release function mylar or paper, the second layer of base material is made of acryl resin film which is a interlayer between the first layer of acryl resin adhesive and the third layer of acryl resin adhesive, characterized in that three layers of acryl resin adhesive layers are melted into a whole body after being coated or heated, and proper tractility and heat resistance are provided. When the utility model is applied to procedures such as film slitting, stripping and so on, and the release function mylar or paper is torn off, edge fracture caused by adhering and pulling mutually occurring in prior art is prevented in the case of the integral acryl resin adhesive layer, thereby adding use value.

Description

Fusion type base material adhesive tape

Technical field

The utility model is a kind of fusion type base material adhesive tape, be meant a kind of structure of fusion type base material especially, this adhesive tape utilizes the acryl resin film when middle base material, after coating or heat-processed, after combining together with the acryl resin tackiness agent, have suitable ductility and thermotolerance, when tear off release function mylar or paper to the acryl resin adhering agent layer not can because of bonded to each other pull produce break, make this adhesive tape to have no base material adhesive tape and base material adhesive tape characteristics concurrently, can improve that film is cut, the precision of stamp, itemize.

Background technology

No base material double sticky tape is good because of transparency and texture, so very popular: generally be applied to office supplies or replace solid in order to paste the industrialness spare part.

As shown in Figure 2, no base material double sticky tape V commonly used is coated with one deck colloid B between two release film R, R1, after tearing release film R, R1 off, follow with article respectively with the two sides of colloid B.General no base material double sticky tape V storEs not account for usage space with rolling as shown in Figure 1.

Because general no base material double sticky tape has the characteristic of good ductility, thermotolerance, clinging power, when film is cut, originally the part of punching separation can be in adhesion (promptly after-tacking) mutually when tearing off on for some time two limit behind the stamp, itemize, colloid B and colloid B because of bonded to each other pull to produce break, cause and be difficult for precisely and the affixed object applying, cause also that film is cut, the exquisite degree of stamp, itemize is difficult for, so that generation part in colloid B surface is imperfect in the course of processing, as shown in Figure 3, reduce the processed goods qualification rate.

The utility model content

The purpose of this utility model is to overcome the problems referred to above, and a kind of fusion type base material adhesive tape is provided.

The fusion type base material adhesive tape that the utility model provides comprises acryl resin film base material and acryl resin tackiness agent, and wherein, the acryl resin film is positioned at the centre or a side of this acryl resin tackiness agent.

As the optimization to technique scheme, the acryl resin film thickness is between the 650um to 2um.

As the optimization to technique scheme, a side coating thickness of acryl resin tackiness agent is between the 1um to 60um.

As the optimization to technique scheme, the thickness of a side of acryl resin tackiness agent or two sides coating acryl resin tackiness agent can be unequal thickness.

As the optimization to technique scheme, the tackiness agent of a side of acryl resin tackiness agent or two sides coating acryl resin tackiness agent can be unequal clinging power.

As optimization to technique scheme, a side of acryl resin film coating acryl resin tackiness agent, opposite side can be coated with other resin layers.

No base material formula double sticky tape is good because of adhesion reaches texture by force, so very popular: generally be applied to office supplies or replace solid in order to paste the industrialness spare part.

As shown in Figure 2, no base material formula double sticky tape commonly used is coated with one deck colloid between two release films, after tearing release film off, follow with article respectively with the colloidal two sides.

A kind of fusion type base material adhesive tape, comprise two-sided release function mylar or paper, and the acryl resin tackiness agent between release function mylar of coating or the paper, wherein, mylar or paper, the double spread parting agent, and this fusion type base material has three layers of distribution, the one side of the first layer acryl resin tackiness agent and the 3rd lamination gram force resin tackiness agent is bonding with release function mylar or paper respectively, the base material of the second layer is the material of acryl resin film, and it is folded between the first layer acryl resin tackiness agent and the 3rd lamination gram force resin tackiness agent.When resin of the same type after coating, because of the similar event of energy is combined into one, when processing of films is cut, when tearing release function mylar or paper off behind the itemize, for merging the acryl resin tackiness agent, there has not been glue-line respectively, improve past bonded to each other the pullling of glue-line and cause the situation of breaking, have in conjunction with characteristic material of the same type, separately Fa Hui value.

Embodiment

Please join Fig. 4 A, be sectional view of the present utility model.Clearly from figure disclose fusion type base material adhesive tape of the present utility model and comprise release function mylar or paper RP and coat fusion type base material AB between release function mylar or the paper RP.Wherein, release function mylar or paper RP, be the parting agent S1 that mylar or paper PP simultaneously are coated with light off-type force, there are three layers of distribution at parting agent S2 and this acryl resin tackiness agent AB enforcement initial stage of the heavier off-type force of another side coating, the first layer acryl resin tackiness agent AB, second layer acryl resin film base material AT and the 3rd lamination gram force resin tackiness agent AB, the one side of this first layer acryl resin tackiness agent AB second layer acryl resin film AT and the 3rd lamination gram force resin tackiness agent AB is bonding with release function mylar or paper RP respectively, the acryl resin film AT of the second layer then is folded between the first layer acryl resin tackiness agent AB and the 3rd lamination gram force resin tackiness agent AB, since be resin of the same type after coating, it is identical so be combined into one because of energy to implement the back.The utility model main body is that fusion type base material BAB is shown in Fig. 4 B.

Do not have in the past the base material adhesive tape thicker because of glue-line, be easier to produce the jelly effect and make glue-line produce bonded to each other pullling respectively to cause bonding the causing mutually in edge of edge breaks situation or release function mylar after film is cut or paper RP to pull, destroy the complete of former glue-line.This fusion type base material BAB is caused by acryl resin film AT and tears release function mylar off or paper RP can not produce bonded to each other the pullling of glue-line of cut-out and cause the situation of breaking fusion type base material adhesive tape, and then reach qualification rate in the course of processing, paste smooth and easy, keep clean, increase precision.
