Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.

Fig. 1-5, a kind of durable type PVC diaphragms, including protection membrane body 1 are referred to, the inside of protection membrane body 1 is set There is matrix 2, in life and production, people are in order to keep cleaning and the safety of article, it will usually in the surface covering of article Diaphragm, so as to be protected to article, makes article keep novel, so that seem more beautiful, it is more suitable when using The heart, and diaphragm can also play certain protective action, it is to avoid and article is because rubbing by breakage, and the upper surface of matrix 2 is set Overcoat 3 is equipped with, matrix 2 is protected, it is to avoid matrix 2 is damaged, extends the service life of diaphragm, matrix 2 Lower surface is provided with lower overcoat 4, is used cooperatively with upper overcoat 3, carries out double protection, and not only protecting effect is more preferable, and Protection film strength can be strengthened, diaphragm is not readily susceptible to damage, extend under the service life of diaphragm, lower overcoat 4 Bonding strip 6 is fixedly connected with the outside of surface, it is convenient to be attached diaphragm with article, and diaphragm and article can be made Between connect it is even closer, article can be avoided to be made dirty by the dust in air, and waterproof can be played a part of, make thing It is safer that product are placed, and bonding strip 6 includes longitudinal bonding strip and lateral bond bar, and longitudinal bonding strip and lateral bond bar two Be mutually connected vertically from beginning to end between two, ensure diaphragm by article thorough seal on the basis of, it is possible to reduce diaphragm with The area connected between connector, reduces adhesion of the adhesive glue to connector, convenient to remove diaphragm, reduces the residual of adhesive glue Stay, it is to avoid cost can not only be reduced by making connector dirty, and reducing the use of glue, can also be reduced the pollution to environment, be made With more environmentally-friendly, coherent mass 5 is fixedly connected with the middle part of the lower lower surface of overcoat 4, makes the stability that diaphragm is connected more preferably, keeps away Protection film-free departs from article, and upper overcoat 3 includes outermost waterproof layer 31, it is to avoid tack coat 43 is led because of the erosion by water Cause bonding it is insecure, it is to avoid influence diaphragm use, and can avoid water influence article placement, waterproof layer 31 it is interior Surface is connected with glass layer 32, and the inner surface of glass layer 32 is connected with enhancement layer 33, and upper enhancement layer 33 includes base Layer 333, the outer surface of basic unit 333 is respectively arranged with crisscross transverse fiber layer 331 and longitudinal fiber layer 332, not only may be used To strengthen protection film strength, and make the toughness of diaphragm more preferable, it is not easy to be damaged, make diaphragm more durable, The service life of diaphragm can be extended, without frequent replacing diaphragm, cost can be saved, and resource can be reduced Waste, reduce the pollution to environment, lower overcoat 4 includes outermost tack coat 43, facilitates diaphragm to be attached with article, The inner surface of tack coat 43 is connected with polyethylene fiber layer 42, is used cooperatively with glass layer 32, can both strengthen diaphragm Intensity, the pliability of diaphragm can be strengthened again, make diaphragm be not readily susceptible to damage, the use longevity of diaphragm can be extended Life, reduces cost, and the inner surface of polyethylene fiber layer 42 is connected with inside lower enhancement layer 41, lower enhancement layer 41 and upper enhancement layer 33 Structure it is identical.

In summary：Durable type PVC diaphragms, by being provided with bonding strip 6 and coherent mass 5 in the bottom of diaphragm, The area connected between diaphragm and connector is reduced, adhesion of the adhesive glue to connector is reduced, it is convenient to remove diaphragm, subtract The residual of few adhesive glue, it is to avoid cost can not only be reduced by making connector dirty, and reducing the use of glue, can also be reduced to ring The pollution in border, using more environmentally-friendly, solves the problem of being easily damaged in the prior art.
