Abstract
The utility model discloses a compound PVB film, including the film main part, the film main part includes that the film is two -layer with lower film, go up the film with be provided with the heat preservation down between the film, it is provided with the flame retardant coating to go up between film or lower film and the heat preservation. The utility model relates to a compound PVB film, with glass synergism, very big improvement thermal insulation performance and fire behavior, practical value more has.
Description
Technical field
The utility model relates to polymeric membrane field, in particular to a kind of compound PVB film.
Background technology
PVB film plastifies extruded a kind of macromolecular material by polyvinyl butyral resin through softening agent, it not only outward appearance be semitransparent thin film, and inclusion-free, surfacing, there are certain roughness and good flexibility, unorganic glass is had good cohesive force, there is the characteristics such as wet, physical strength height transparent, heat-resisting, cold-resistant, resistance to, being the optimum adhesion material manufacturing interlayer, shatter proof glass on our times, the building field such as curtain wall in mansion, handrail, guardrail, airport, show window, steel melting furnace screen and various splinter-proof glasses is widely used. Along with development and the growth in the living standard of urbanization, heat retention and fire line to laminated glass are had higher requirement, and prior art cannot meet the demand of people.
Summary of the invention
Technical problem to be solved in the utility model is: the deficiency existed for prior art, it is provided that a kind of compound PVB film, with glass synergy, greatly improves heat-insulating property and fire resistance, has more practical value.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of compound PVB film, comprises film main body, and described film main body comprises film and two layers, lower film, is provided with thermal insulation layer between described upper film and described lower film, described upper film or be provided with fireproofing between lower film and thermal insulation layer.
As the preferred scheme of one, described thermal insulation layer is glass wool layer.
As the preferred scheme of one, described thermal insulation layer is aerogel carpet veneer.
As the preferred scheme of one, described fireproofing is fire retardant coating.
Owing to have employed technique scheme, the beneficial effects of the utility model are:
A kind of compound PVB film that the utility model relates to, comprise film and lower film respectively with unorganic glass close adhesion, centre is provided with thermal insulation layer, the setting of thermal insulation layer, the effect preventing indoor heat diffusion and outdoor heat from entering can be played, play effect cool in summer and warm in winter. Meanwhile, the setting of fireproofing, when being applied in shatter proof glass, acts synergistically with shatter proof glass, it is to increase safety index.
Described thermal insulation layer is glass wool layer, and glass wool is as a kind of lagging material, and abundant raw material, makes simple, and effect is good.
Described thermal insulation layer is aerogel carpet veneer, and aerogel blanket is taking nanometer titanium dioxide silica aerogel as material of main part, the flexible heat-insulating felt being composited with glass fibre cotton or preoxidized fiber felt by special process. Having heat insulation effect good, material thinner thickness, has the advantage of fire resistance concurrently.
Described fireproofing is fire retardant coating, has simple to operate, the significant advantage of effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is illustrated further.
Fig. 1 is the structural representation of the utility model embodiment;
In figure, the upper film of 1-; 2-thermal insulation layer; 3-fireproofing; Film under 4-.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.
As shown in Figure 1, a kind of compound PVB film, comprises film main body, and described film main body comprises film 1 and 4 two layers, lower film, it is provided with thermal insulation layer 2, described upper film 1 or be provided with fireproofing 3 between lower film 4 and thermal insulation layer 2 between described upper film 1 and described lower film 4.
During preparation, applying fireproofing 3 on upper film 1, covering and heat insulating layer 2 on fireproofing 2, finally sticky and lower film 4 is on thermal insulation layer 2, and PVB film completes.
During by the insulation PVB film of the present embodiment for the preparation of laminated glass, first the upper film 1 of insulation PVB film and lower film 4 are fitted with layer glass respectively, then vacuumize, and periphery is carried out edge sealing, ensureing the vacuum state between PVB film main body and glass, laminated glass completes.
The foregoing is only better embodiment of the present utility model; not in order to limit the utility model; all any amendment, equivalent replacement and improvement etc. done within spirit of the present utility model and principle, all should be included within protection domain of the present utility model.
