Description
Technical Field
The utility model relates to a paste the technical field of pressure sensitive glued membrane on the quilt thing (metalwork, working of plastics etc.), especially a reduce to play to shell glued membrane of power.
Background
The structure of the existing adhesive film is shown in figure 1, and the existing adhesive film comprises a protective film 2 adhered to the bottom surface of a positioning film 1 and a pressure-sensitive adhesive film 3 adhered to the bottom surface of the protective film, wherein the pressure-sensitive adhesive film 3 and the protective film 2 are required to be adhered to a metal piece technically, the existing adhesive film adhering mode is that the surface of the metal piece to be adhered with the film is upward and is placed in a cavity of a clamp body to realize the positioning of the metal piece, then an adhesive layer on the bottom surface of the pressure-sensitive adhesive film 3 is adhered to the metal piece 5, the positioning film 3 is pressed downwards by hands to be adhered to the metal piece 5 as shown in figure 2, then the positioning film 1 is pulled down from the protective film 2 from left to right, and at the moment, the pressure-sensitive adhesive film 3 and the protective film 2 on the metal piece are left, so that the film-adhering pressure-sensitive adhesive film is finally realized. Wherein, at the initial stage of tearing registration film 1, because protection film 2 pastes completely on registration film 1 to increased and peeled the power, caused the gassing between protection film 2 and the pressure-sensitive adhesive film 3, but also can cause protection film 2 to tear from pressure-sensitive adhesive film 3, thereby reduced the pad pasting quality, the product after the pad pasting can't reach customer's operation requirement. Therefore, there is a need for an adhesive film that reduces peeling force, prevents the generation of bubbles or tears the protective film from the pressure-sensitive adhesive film, and improves the quality of the adhesive film.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's shortcoming, provide a compact structure, avoid producing the bubble or with the protection film tear from pressure-sensitive adhesive film get off, improve the reduction of pad pasting quality and play the glued membrane of power of peeling.
The purpose of the utility model is realized through the following technical scheme: an adhesive film for reducing peeling force comprises a positioning film, a protective film, a pressure-sensitive adhesive film and an inviscid diaphragm, wherein an adhesive layer on the top surface of the pressure-sensitive adhesive film is adhered to the bottom surface of the protective film, the inviscid diaphragm is arranged on the top surface of the protective film and positioned at the left end part of the protective film, the inviscid diaphragm extends to the left outside the protective film, the positioning film covers the top surface of the inviscid diaphragm and is adhered on the adhesive layer on the top surface of the protective film; when the positioning film is peeled, the positioning film is peeled from the left end of the positioning film, and the positioning film is torn to the right, so that the positioning film is torn from the protective film.
The positioning film is provided with a positioning hole, and the contact surface of the positioning film and the protective film is sticky.
The non-adhesive diaphragm is a polyester film.
The left end face of protection film and the left end face parallel and level of pressure-sensitive glued membrane, the right-hand member face of protection film extends in the outside of pressure-sensitive glued membrane.
The utility model has the advantages of it is following: the utility model discloses compact structure, avoid producing the bubble or tear the protection film from pressure-sensitive adhesive film, improve the pad pasting quality, reduce to play and shell the power.

Detailed Description
The invention will be further described with reference to the accompanying drawings, without limiting the scope of the invention to the following:
as shown in fig. 3, an adhesive film for reducing peeling force comprises a positioning film 1, a protective film 2, a pressure-sensitive adhesive film 3 and a non-adhesive diaphragm 4, wherein an adhesive layer on the top surface of the pressure-sensitive adhesive film 3 is adhered to the bottom surface of the protective film 2, the non-adhesive diaphragm 4 is placed on the top surface of the protective film 2 and positioned at the left end part of the top surface, the non-adhesive diaphragm 4 extends to the left outside of the protective film 2, the positioning film 1 covers the top surface of the non-adhesive diaphragm 4 and is adhered on the adhesive layer on the top surface of the protective film 2; when the positioning film 1 is peeled, the positioning film 1 is peeled from the left end portion of the positioning film 1, and the positioning film 1 is pulled rightward to tear the positioning film 1 from the protective film 2.
The positioning film 1 is provided with a positioning hole, and the contact surface of the positioning film 1 and the protective film 2 is sticky. The non-adhesive diaphragm 4 is a polyester film. The left end face of protection film 2 and the left end face parallel and level of pressure-sensitive glued membrane 3, the right-hand member face of protection film 2 extends in the outside of pressure-sensitive glued membrane 3, protection film 2 is the sticky film of single-sided tape or for the inviscid from the type membrane, and the difference lies in: when the pressure-sensitive adhesive film 3 is a single-sided adhesive, the corresponding protective film 2 is a thin film, and when the pressure-sensitive adhesive film 3 is a double-sided adhesive, the corresponding protective film 2 is a release film.
The working process of the utility model is as follows:
treat that the pad pasting face of metalwork is upwards and place in the die cavity of anchor clamps body earlier, in order to realize the location of metalwork, then paste the adhesive layer of pressure-sensitive adhesive film 3 bottom surface on metalwork 5, reuse hand pushes down locating film 1, in order to paste pressure-sensitive adhesive film 3 on the metalwork as shown in figure 4, when peeling off locating film 1, begin to peel off locating film 1 from the left end of locating film 1, tear locating film 1 to the right, in order to tear locating film 1 from protection film 2, pressure-sensitive adhesive film 3 and the last protection film 2 of this moment then stay on metalwork 5, thereby finally realized pad pasting pressure-sensitive adhesive film.
Because inviscid diaphragm 4 presss from both sides between registration film 1 and protection film 2, consequently reduced the bonding area between protection film 2 and the registration film 1 to reduce the adhesive force between the two, and then reduced and peeled the power, make things convenient for the workman to tear registration film 1 from protection film 2 easily. Because the peeling force is reduced, the generation of bubbles between the protective film 2 and the pressure-sensitive adhesive film 3 is avoided, the protective film 2 and the pressure-sensitive adhesive film 3 are prevented from being layered, namely, the protective film 2 is also torn from the pressure-sensitive adhesive film 3, the traditional adhesive film is compared, the film sticking quality is greatly improved, and the requirements of customers are met.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
