Abstract
The utility model discloses a two-way stretched polyester safety film for art glass, which is applied in the art glass film field and having the effects of safety, shading and decorating. The safety film comprises a base material, a middle layer and a hot melting adhesive layer, wherein the base material is a white two-way stretched polyester film; the middle layer is made of polymine; and the hot melting adhesive layer is ethylene-vinyl acetate hot melting adhesive. The middle layer is uniformly coated on one surface of the base material, and the surface of the middle layer is uniformly composited with the hot melting adhesive layer. For the thickness, the base material is 25-75 micron, the middle layer is 0.01-0.03 micron, and the hot melting adhesive layer is 25-75 micron. The safety film has the effects that: the art glass can be protected, even if the art glass is broken, the pieces of the art glass are stuck on the safety film, therefore, the personal injury and the property damage caused by the falling off of the broken glass can be avoided. In addition, as the base material adopts the white polyester film, the art glass can be protected and supported, and a white substrate is provided, therefore, the safety film has the shading effect, and the decorative effect is improved.
Description
Technical field
The utility model relates to the overlay film field, and particularly a kind of art glass notacoria that safety, decorate properties requirement are arranged is a kind of pre-coating film that adopts extrusion composite technology to make.
Background technology
Now, in the construction industry trend that is extensive use of glass, art glass more and more is subjected to liking of human consumer with the characteristics such as perfect adaptation of its artistry and practicality, is widely used in the positions such as screen, entry, wall and space partition of hotel, hotel, teahouse, home decoration.But because glass material is frangible, glass fragment is hurted sb.'s feelings easily, and its security receives publicity day by day.
Along with the technical development of glass industry, safety interlayer glass has obtained fast development and widespread use owing to have good security, shock resistance and penetration-resistant energy.Safety interlayer glass is by tough and tensile inner plastic (PVB) two sheet glass to be pasted to form under certain temperature and pressure, why it is safely because its inner plastic can absorb portion of energy and the shock wave pressure that is produced in impact and the blast process, when glass fragmentation faced, the PVB film can stick together glass fragment, can not scatter and splash, prevented that effectively fragment from stabbing and penetrating the generation of fall event, guaranteed personnel safety.Safety interlayer glass is mainly used in the position that particular requirement is arranged in transportation and communication and the buildings.
But safety interlayer glass complex manufacturing technology, yield rate is relatively low, adds that PVB film price is higher, and main for a long time dependence on import causes the safety interlayer glass cost high.And the PVB film can only be applied to exist certain application limitation in the middle of the layer glass, and is powerless for the security of the art glass of individual layer.
The utility model content
The purpose of this utility model is: a kind of biaxial stretching polyester art glass safety film is provided, be applied to individual layer art glass notacoria, can play the safeguard protection effect: in case after the glass fragmentation, glass fragment can be bonded on the safety film, prevent that glass from splashing, can prevent effectively that fragment from stabbing and penetrating falls, and guarantees personnel safety; The white polyester base material provides the backboard effect simultaneously, and its white substrate both can strengthen the decorative effect of art glass, and its good resistance optical property can satisfy the application scenario that client has relatively high expectations to opacifying property.
The technical solution adopted in the utility model is: biaxial stretching polyester art glass safety film, comprise base material, middle layer and hot melt adhesive layer, and the width of base material, middle layer and hot melt adhesive layer is identical.It is characterized in that: base material is two-way stretch white polyester (BOPET) film; The middle layer is polymine (PEI); Hot melt adhesive layer is ethene-vinyl acetate (EVA) hot melt adhesive.The middle layer evenly is coated on the surface of base material, even composite hot melt glue-line on the surface in middle layer.The thickness of base material is between 25～75 microns, and (coated weight is 0.009～0.011g/m to the thickness in middle layer at 0.01～0.03 micron
2) between, the thickness of hot melt adhesive layer is between 25～75 microns.
Technical scheme is preferably: the thickness of base material is between 25～50 microns, and (coated weight is 0.009～0.01g/m to the thickness in middle layer at 0.01～0.02 micron
2) between, hot melt adhesive layer compound thickness is between 25～50 microns.
The composite production line that utilizes forcing machine and equipment complex to form is coated in the middle layer on the surface of base material, at last hot melt adhesive layer is compounded on the middle layer, produces biaxial stretching polyester art glass safety film.After the thickness of base material and hot melt adhesive layer carries out suitable combination, can obtain different products.Above-mentioned forcing machine and equipment complex and recombining process are well known to those skilled in the art.
The EVA hot melt adhesive is a kind of solvent, solid meltability polymkeric substance of water content not of not needing; Be solid at normal temperatures, heating and melting becomes and can flow to certain temperature, and the liquid of certain viscosity is arranged.EVA hot melt adhesive after the fusion is light yellow or colourless.The EVA hot melt adhesive is become to be grouped into by basic resin, tackifier, viscosity modifier and oxidation inhibitor etc.At present, apply level EVA hot melt adhesive product and mainly rely on import, domestic no appropriate level products production.
Polymine (PEI) molecular formula is: [CH
2CH
2NH-] n, there is product-feed in Shanghai DiC Ink Co., Ltd, and our company adopts U.S.'s imported product.
Two-way stretch white polyester (BOPET) film is the plastics film with certain width and thickness, white, and higher physical strength and toughness are arranged, and also has good resistance optical property.At present, domestic have a lot of manufacturers that two-way stretch white polyester (BOPET) film can be provided, as the U.S. film of rainbow company limited, Kunshan Shu Dao insulating material company limited etc.
The beneficial effects of the utility model: the utility model biaxial stretching polyester art glass safety film; with two-way stretch white polyester (BOPET) film as base material; with the pre-coating film of ethene-vinyl acetate (EVA) hot melt adhesive as hot melt adhesive layer; adopt the vacuum lamination technology; can be applied to art glass notacoria field; can play the safeguard protection effect; fragment can be bonded at after glass is destroyed and prevent on the film that fragment from splashing and cause personal injury and property damage; its white polyester base material can also play the backboard effect simultaneously; except protection is supported; its white substrate both can strengthen the decorative effect of art glass; and its good resistance optical property can satisfy the application scenario that client has relatively high expectations to opacifying property, especially suitable hotel; the stream of peoples such as hotel cut off with on the art glass greatly and to the screen that safety performance is had relatively high expectations.And coating technique is simple, the yield rate height, and the cost of material is low, certainly will fill up the blank in art glass safeguard protection field.
