Abstract
The utility model relates to an adhesive film for sandwich glass, in particular to a PVB film for preventing the generation of bubbles. The PVB film comprises a film main body, a plurality of mutually-parallel arc-shaped grooves passing through the film main body are formed in the upper surface and the lower surface of the film main body respectively, the arc-shaped transition is adopted between the edges of the grooves and the surface of the film main body; a plurality of cavities with annular cross sections are formed inside the film main body in the preparation process of the film main body. According to the PVB film for preventing the generation the bubbles, in the process that the PVB film is manufactured to the sandwich glass, the generation of the bubbles between the PVB main body and the glass can be avoided, the problem that the bonding strength is lowered as the contact of the PVB main body and the glass is bad due to the generation of the bubbles is solved; moreover, the bonding strength of the PVB main body and the glass is strengthened by the formation of the vacuum between the PVB main body and the glass, and the prepared sandwich glass has a sound-proof effect in some extent at the same time accordingly.
Description
Technical field
The utility model relates to a kind of laminated glass-use adhesive sheet, is specifically related to a kind of PVB film that prevents Bubble formation.
Background technology
Polyvinyl butyral acetal PVB is the condenses of polyvinyl alcohol and butyraldehyde, and PVB at home topmost Application Areas is to be applied in the laminated glass as intermediate coat.The PVB intermediate coat is by a kind of macromolecular material of polyvinyl butyral resin through softening agent plasticizing extrusion molding, it not only outward appearance be semitransparent thin film, and inclusion-free, surfacing, certain roughness and good flexibility are arranged, unorganic glass there is good cohesive force, have transparent, heat-resisting, cold-resistant, moisture-proof, the characteristics such as physical strength height, to make interlayer on the our times, the optimum adhesion material that shatter proof glass is used is simultaneously at building curtain wall, recruit awning, show window, bank counter, window is visited in the prison, the building fields such as steel melting furnace screen and various splinter-proof glasses also are widely used.In the preparation process of laminated glass and since to operation require too highly so that be easy between glass and PVB film to form irregular bubble, these bubbles are very difficult to be eliminated it by the mode that vacuumizes.The residual of bubble also stayed hidden danger for the quality and performance of laminated glass.
Application number is that 03277474.5 utility model patent discloses the special-purpose lathe work film of a kind of laminated glass, and it is to connect one deck lathe work printing ink at film, and this film has reduced the cost of color pattern glass, has improved the yield rate of color pattern glass.But this glass film can not be avoided forming bubble in the preparation process of laminated glass between glass and film, and the problem that the laminated glass applying intensity that can not avoid bubble to cause is lower occurs.
The utility model content
The purpose of this utility model provides a kind of PVB film that prevents Bubble formation, present laminated glass easily forms bubble between glass and PVB film in preparation process so that there is the unsettled problem of intensity in laminated glass to solve, thereby has greatly improved the applying firmness of laminated glass.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of PVB film that prevents Bubble formation comprises the film main body, and the upper and lower surface of film main body is provided with the groove of some perforation film main bodys.When adopting the PVB film to prepare laminated glass, need to be to vacuumizing to impel PVB film and the better combination of glass between PVB film and glass, and the surface of present PVB film is because whole smooth, in preparation process, be easy between PVB film and glass, form small bubbles, and these are distributed in the bubble away from the edge, but are difficult for being pumped.Residual bubble has brought hidden danger to the quality of glass.By in PVB film main body upper and lower surface groove being set, thereby can as much as possible the air between the contact surface of PVB film main body and glass be taken away, in groove, form vacuum simultaneously, improve the conjugation of PVB film main body and glass.
As preferred version, described groove be arranged in parallel.The groove of parallel distribution can be taken out the air between PVB film main body and the glass equably, increases the conjugation between PVB film main body and the glass.
As preferred version, described groove is deep-slotted chip breaker, and recess edge and film body surfaces arc-shaped transition.Arc can reduce stress concentration, prevents strength decreased.
As preferred version, be provided with a plurality of equally distributed cavities of establishing in the described film main body.Air in the cavity can play deadening.
As preferred version, the cross section of described cavity is circular.Circular cross section can prevent the intensity of PVB film to greatest extent.
Because adopt technique scheme, the beneficial effects of the utility model are: can prevent from producing bubble between PVB film and glass, avoid the generation of bubble to cause PVB film and the bad strength decreased of fitting that causes of glass contact; By between PVB film and glass, forming the conjugation that vacuum is strengthened PVB film and glass, simultaneously so that the laminated glass of preparation has certain soundproof effect.
Description of drawings
Fig. 1 is a kind of longitudinal sectional view of the present utility model.
Among the figure: 1 film main body, 2 grooves, 3 cavities.
Embodiment
The below is further described the utility model with specific embodiment.
Embodiment
A kind of PVB film that prevents Bubble formation, as shown in Figure 1, comprise film main body 1, the upper and lower surface of film main body 1 is provided with a plurality of grooves 2 that are parallel to each other and connect film main body 1, these grooves 2 are deep-slotted chip breaker, and groove 2 edges and film main body 1 surperficial arc-shaped transition, in addition in the preparation process of film main body 1 within it section's Formation cross-section be circular a plurality of cavities 3, play deadening to form air casing.
With the PVB film that prevents Bubble formation of the present embodiment during for the preparation of laminated glass, at first PVB film and layer glass are fitted, then vacuumize, and periphery is carried out edge sealing, guarantee PVB film main body and vacuum state, then carry out next step operation.It is good that the laminated glass for preparing has an applying degree, and can play to a certain extent soundproof effect.
