Abstract
The utility model discloses an anti double faced adhesive tape that draws that tears, including the cotton layer of middle bubble, the upper and lower terminal surface on the cotton layer of middle bubble covers the film that the one deck has toughness, the surface of film carries out the rubber coating and forms the rubber coating, the surface on rubber coating covers from type paper. The utility model discloses cover the one deck film that has toughness through covering the technology on the surface on middle bubble cotton layer, the film can play the effect that anti tearing were drawn, makes this anti tearing draw the tensile difficult fracture of double faced adhesive tape, and solves to tear and have the remaining problem of cull. The anti-tearing double-faced adhesive tape after being coated with the film has a three-layer structure, the middle of the anti-tearing double-faced adhesive tape is a middle foam layer, the upper layer and the lower layer of the surface of the anti-tearing double-faced adhesive tape are thin films, and the thin films have waterproof capacity and can be protected from being normally used in a humid environment.
Description
Technical Field
The utility model relates to a double faced adhesive tape technical field specifically is an anti double faced adhesive tape that draws that tears.
Background
The use field of the foam double faced adhesive tape is very wide, and the foam double faced adhesive tape is mainly used for some household products, such as: the application of double faced adhesive tape on these products provides great convenience for people's life, makes the product that originally need to beat the screw, beat the nail and just can use, and it is more convenient to use.
The bubble cotton double faced adhesive tape in the existing market has the problems that the tearing resistance is poor, the tearing is easy to break, and the residual adhesive is left in the bubble cotton after the tearing. The foam double-sided adhesive tape on the market at present is single in structure, only has one layer of foam adhesive, has no waterproof capability because the upper surface and the lower surface are directly coated with the adhesive, and easily loses viscosity in a humid environment. To this end, we have proposed a tear-resistant double-sided adhesive.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide an anti double faced adhesive tape that draws that tears to solve the problem that proposes in the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an anti-tear draws double faced adhesive tape, includes middle bubble cotton layer, the upper and lower terminal surface on middle bubble cotton layer covers the film that the one deck has the toughness, the surface of film carries out the rubber coating and forms the rubber coating, the surface on rubber coating covers from type paper.
As a further optimization of the technical scheme, the thickness of the film is smaller than that of the glue coating layer, and the thickness of the glue coating layer is 0.3-0.5 mm.
As a further optimization of the technical scheme, the thickness of the middle foam layer is 1-2 mm.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses cover the one deck film that has toughness through covering the technology on the surface on middle bubble cotton layer, the film can play the effect that anti tearing were drawn, makes this anti tearing draw the tensile difficult fracture of double faced adhesive tape, and solves to tear and have the remaining problem of cull.
The anti-tearing double-faced adhesive tape after being coated with the film has a three-layer structure, the middle of the anti-tearing double-faced adhesive tape is a middle foam layer, the upper layer and the lower layer of the surface of the anti-tearing double-faced adhesive tape are thin films, and the thin films have waterproof capacity and can be protected from being normally used in a humid environment.
Drawings
Fig. 1 is a schematic sectional view of the present invention.
In the figure: 1 middle foam layer, 2 thin film, 3 glue coating layer and 4 release paper.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: the utility model provides an anti-tear draws double faced adhesive tape, includes middle bubble cotton layer 1, the upper and lower terminal surface on middle bubble cotton layer 1 covers one deck film 2 that has the toughness, the surface of film 2 is carried out the rubber coating and is formed rubber coating 3, the surface of rubber coating 3 covers from type paper 4.
The thickness of the film 2 is less than that of the glue coating layer 3, and the thickness of the glue coating layer 3 is 0.3-0.5 mm.
The thickness of the middle foam layer 1 is 1-2 mm. The middle foam layer 1 is a main body of the tearing-resistant double-sided adhesive tape, a layer of tough film 2 is coated on the surface of the middle foam layer 1 through a coating process, the surface of the film 2 is coated with glue, and then release paper 4 is coated on the surface of the glue coating layer 3 to protect the viscosity of the glue coating layer 3.
The working process is as follows: after anti tear double faced adhesive tape covers film 2 that has the toughness, anti tear ability reinforce, when pulling anti tear double faced adhesive tape hard, because film 2 and middle bubble cotton layer 1 cover together, middle bubble cotton layer 1 is torn apart easily, and will tear after tearing the double faced adhesive tape from the plane of pasting, will not have middle bubble cotton layer 1 to remain on it, film 2 has consolidated middle bubble cotton layer 1's completeness. Because the middle foam layer 1 is covered with the film 2, water is not easy to invade the middle foam layer 1 main body, and the waterproof capability of the tear-resistant double-sided adhesive tape is improved.
The working principle is as follows: the surface of the foam (namely the middle foam layer 1) is coated with glue, so that the front side and the back side can be stuck together, and two objects can be stuck together. The surface of the common double-sided adhesive tape is not coated with a film, and the double-sided adhesive tape can be pulled and broken along with the lapse of time if the double-sided adhesive tape is hung for a long time and is a heavy object, so that the double-sided adhesive tape loses the function.
The structure to the double faced adhesive tape has now been improved, the upper and lower surface on middle bubble cotton layer 1, respectively cover one deck film 2 that has toughness, can play the effect of its complete degree of stabilizing to middle bubble cotton layer 1, pull hard and can not split, paste and tear also can not have the cotton cull of bubble after leaving over, film 2 also can play waterproof effect, water can't see through 2 invasion bubbles of film cotton, play the effect of this anti-tearing double faced adhesive nature of protection.
The structure of the double-sided adhesive tape is improved, and a layer of flexible film 2 is coated on the upper surface and the lower surface of a middle foam layer 1 of the double-sided adhesive tape through a coating process.
The film 2 can play a role in consolidating the integrity of the foam for the middle foam layer 1, and prevent the foam from being torn by tension;
the film 2 may also serve a waterproof function, allowing the tear-resistant double-sided adhesive tape to be used in a wet environment.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
