Abstract

The utility model discloses unbounded glass which comprises glass and a composite membrane; the composite membrane comprises a first PET (polyethylene glycol terephthalate) membrane layer, a PVC (polyvinyl chloride) membrane layer and a low-shrink membrane layer the shrink rate of which is lower than that of the PVC membrane layer; the first PET membrane layer is bonded on one surface of the PVC membrane layer through a bonding layer 1; the low-shrink membrane layer is bonded on the other surface of the PVC membrane layer through a bonding layer 2; and the low-shrink membrane layer is bonded on one surface of the glass through a bonding layer 3. The bound of glass and the bound of the composite membrane in the unbounded glass are mutually matched as far as possible; the composite membrane has small shrink amplitude so as to improve the appearance quality of the unbounded glass.

Description

A kind of unbounded glass

Technical field

The utility model relates to a kind of glass, refers to especially the unbounded glass that a kind of Rimless uses.

Background technology

At present; for the kind industry of glass newborn a kind of unbounded glass again; this unbounded glass is relative with the definition of bounded glass; bounded glass refers to that at least one limit of monolithic glass is equipped with frame; and unbounded glass refers to do the Rimless monolithic glass of whole purposes, because unbounded glass generally is to post film with outward appearance kind and the quality of cover glass and raising glass.Except a glass, wrap up in addition the frame of glass edge such as the panel of former refrigerator, air-conditioning, this is exactly the application of bounded glass, and present popular unbounded glass, with the glass of the monoblock Rimless panel as electrical equipment, its beautiful appearance is generous, more and more has been subject to consumer's favor.Right in the use procedure of unbounded glass, unbounded glass needs pad pasting such as PVC/PET composite membrane, this composite membrane is the meeting overall shrinkage after adhering to use a period of time, make the border of composite membrane less than Glazed fence, phenomenon bounded glass can utilize frame to block like this, then be completely exposed in the unbounded glass, obvious mould border has just appearred in the edge of unbounded glass, makes the exterior quality degradation of product.

The utility model content

Technical problem to be solved in the utility model is: the unbounded glass that provides the border of a kind of border of glass and rete to mate as far as possible, and to improve the exterior quality of unbounded glass.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of unbounded glass, comprise glass and composite membrane, this composite membrane comprises a PET rete, PVC rete, than the low low contraction rete of PVC rete shrinkage factor, the one PET rete pass through the surface that tack coat one adheres to the PVC rete, should low shrink rete and adhere to another surface of PVC rete by tack coat two, this low-shrinkage rete sticks on the surface of glass by tack coat three.

As a kind of preferred scheme, described low contraction rete is the 2nd PET rete.

As a kind of preferred scheme, the surplus next surface of a described PET rete is provided with the stamp dyed layer.

As a kind of preferred scheme, the surplus next surface of described stamp dyed layer is provided with the UV protective layer.

As a kind of preferred scheme, another surface of described glass also is stained with the PE protective layer.

After having adopted technique scheme, effect of the present utility model is: owing to be bonded in the composite membrane of glass surface, the PVC rete is PET rete and low the contraction between the rete, because the shrinkage ratio PVC's of PET rete is low, and the shrinkage factor of low contraction rete is also low than PVC, so, PVC rete two sides when autogenous shrinkage all is subject to the power opposite with its convergent force, like this, forcing PVC to reduce shrinks, thereby the border of guaranteeing composite membrane and unbounded glass is basic identical, has improved the aesthetic measure when unbounded glass uses.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structure cutaway view of the utility model embodiment;

Fig. 2 is the structure cutaway view of the composite membrane of the utility model embodiment;

In the accompanying drawing: 1. glass; 2. tack coat three; 3. composite membrane; 31.PVC rete; 32. tack coat one; A 33. PET rete; 34. tack coat two; 35. the 2nd PET rete; 36.UV protective layer; 37. stamp dyed layer; 4.PE protective layer.

The specific embodiment

Below by specific embodiment the utility model is described in further detail.

As depicted in figs. 1 and 2, a kind of unbounded glass, comprise glass 1 and composite membrane 3, this composite membrane 3 comprises a PET rete 33, PVC rete 31, than the low low contraction rete of PVC rete 31 shrinkage factors, the one PET rete 33 pass through the surface that tack coat 1 adheres to PVC rete 31, should low shrink rete and adhere to another surface of PVC rete 31 by tack coat 2 34, this low-shrinkage rete sticks on the surface of glass 1 by tack coat 32.

That is to say, PVC rete 31 is in a PET rete 33 and low the contraction between the rete, and this hangs down and shrinks rete is not that shrinkage factor is lower than how much just be the low rete that shrinks, and needs only lower than the shrinkage factor of PVC rete 31, and the contraction reduction of in use, satisfying composite membrane 3 integral body gets final product.

Therefore, described low contraction rete is preferably the 2nd PET rete 35 with a PET rete 33 identical components.Like this, there is the low PET rete of shrinkage factor on PVC rete 31 two sides, convergent force that the contraction of PVC rete 31 produces has been subject to the restriction of a PET rete 33, the 2nd PET rete 35, the one

PET rete

33,35 pairs of PVC retes of the 2nd PET rete 31 produce a power opposite with this convergent force, like this, this composite membrane 3 is fitted on the glass 1, and composite membrane 3 is in normal contraction scope, its border conforms to substantially with the border of unbounded glass 1, can improve like this outward appearance class of unbounded glass 1.Certainly, can learn according to this principle in fact that the low-temperature shrink rete can also be other retes, be 1.0 ~ 5.0% such as the shrinkage factor of soft PVC, than PVC little PET:1.2 ~ 2.0%, PP:1.2 ~ 2.5% arranged; PE etc.

The surplus next surface of a described PET rete 33 is provided with stamp dyed layer 37.The setting of stamp dyed layer 37 provides the combination of multiple decorative pattern, pattern, color to whole unbounded glass 1, makes its kind abundanter, adapts to the use of different occasions, such as refrigerator, air-conditioning, cabinet etc.

The surplus next surface of described stamp dyed layer 37 is provided with UV protective layer 36.This UV protective layer 36 is made the chromatograph upper surface at stamp and is carried out UV technique hard processing formation.Composite membrane 3 is further protected.

Another surface of described glass 1 also is stained with PE protective layer 4.This PE diaphragm is protected another face of glass 1, avoids scratching, and PE protective layer 4 can be torn when concrete the use.

It is emphasized that; although above-described embodiment has been done more detailed explanation to the utility model; but these explanations are just illustrative to the utility model; rather than to restriction of the present utility model; any substantial utility model that is no more than this utility model is created, and all drops on protection domain of the present utility model.
