Abstract

The utility model discloses a glass protective film which is characterized by comprising a corona layer, an interlayer and a bonding layer, which are glued into a whole in sequence; the aggregate thickness is 10-500 micrometers, and the thickness ratio of the corona layer to the interlayer to the bonding layer is 5% - 60% to 5%- 60% to 2%-40%. The glass protective film has the advantages of ultraviolet radiation resistance, heat absorption and sound insulation, and has simple preparation process and cheap production cost.

Description

A kind of glass protection film

Technical field

The utility model relates to a kind of plastic sheeting, specifically is a kind of glass protection film.

Background technology

What as everyone knows, present building trade door and window generally used is simple glass.On security performance, simple glass can not be kept out the impact that unknown hazards such as bump, blast, earthquake cause, and causes the glass fragmentation, splashes, and these disintegrating slags are easy to human body is damaged; On energy-conservation, the simple glass heat-proof quality is poor, and heat insulation effect is poor, can not ultraviolet radiation preventing.At present, domestic some diaphragm production technologies that occurred, for example the patent No. is the Easily-pasting film of mentioning among the ZL200420109226.7, functions such as no antiultraviolet, heat absorption, sound insulation, and need be undertaken just carrying out sticking glass after the coating adhesive operation by secondary operations, and these adhesives pass to take place shift situation such as peel off probably in time, and operation increases, and production cost can increase; The patent No. is that to provide a kind of be the vacuum coating technology that bottom carries out with glass to ZL200620029222.7; With the utility model the most approaching be that the 200810123979.6 adhering film to glass technology that provide are provided application number, but it is a single layer structure, how not to mention sticking glass.In addition, the glass protection film of being sold on the market is the film from imports such as the U.S., Europe mostly, and complex structure is multi-layer compound structure (being generally 7 layers of structure) that price is higher.

The utility model content

The utility model discloses a kind of glass protection film, it is simple that it has technology, the characteristics of low production cost.

The technical solution of the utility model is:

A kind of glass protection film is characterized in that: include the corona layer, intermediate layer and the adhesive layer that are bonded as one successively, its gross thickness is the 10-500 micron, and each layer thickness ratio is respectively: corona layer 5%-60%, intermediate layer 5%-60%, adhesive layer 2%-40%.

Described glass protection film; the component that it is characterized in that the corona layer is a PETG; the component in intermediate layer is PETG, nano rare earth composite metal oxide and dispersant, and the component of adhesive layer is ethylene-styrene copolymer and hydrogenated petroleum resin.

Described a kind of glass protection film; it is characterized in that: the ratio of the component of described corona layer is a PETG 100%; the ratio of each component of described intermediate layer is PETG 75-95%, nano rare earth composite metal oxide 5-25%, dispersant 0.1-0.5%, and the ratio of each component of described adhesive layer is ethylene-styrene copolymer 50-100%, hydrogenated petroleum resin 0-50%.

Described a kind of glass protection film is characterized in that: the component dispersant in described intermediate layer is selected macromolecule wax for use, includes CeO in the described nano rare earth composite metal oxide ₂, Nd ₂O ₃, ZnO, Eu2O3, Dy2O3, Er ₂O ₃, Y ₂O ₃In one or more.

The preparation method of described glass protection film; comprise following preparation steps: each component in corona layer, intermediate layer and the adhesive layer is mixed respectively in proportion stir; then three layers of each component after the mixing and stirring are put into three-layer co-extruded casting machine machine and carry out three-layer co-extruded film forming; simultaneously it is carried out thickness measurement online, sided corona treatment; guarantee that thickness is the 10-500 micron, then this three-layer co-extruded film is cut edge, rolling, cut, packs.

Advantage of the present utility model is:

(1), ultraviolet radiation preventing: ultraviolet ray is the main cause that causes furniture, curtain, floor, carpet, handicraft etc. to wear out, fade, and the utility model can absorb the ultraviolet ray in the 90% above sunshine, thereby the protection furniture item is avoided destroying;

(2), heat absorption, sound insulation: the utility model can stop the heat that enters the room more than 50% by door and window, stops the heat radiation more than 50%, stops summer external heat to enter, and the air-conditioning service efficiency is provided; Stop winter indoor heat to external radiation, play thermal effect, thereby reach energy saving purposes.The utility model also has the sound insulation function simultaneously, reduces ambient noise and pollutes.

Preparation method of the present utility model is by three-layer co-extruded The tape casting production, and one-shot forming need not carried out second glue spreading processing, do not need compoundly, and technology is simple, and production cost is low.

Description of drawings

Accompanying drawing is the utility model structural representation.

The specific embodiment

The component PETG of corona layer 1 is stirred, with intermediate layer 2 components is PETG 75-95% in proportion, nano rare earth composite metal oxide 5-25%, dispersant 0.1-0.5% mixing and stirring, the component of adhesive layer 3 is ethylene-styrene copolymer 50-100% in proportion, hydrogenated petroleum resin 0-50% mixing and stirring, then three layers of each component after the mixing and stirring are put into three-layer co-extruded casting machine machine and carry out three-layer co-extruded film forming, simultaneously it is carried out thickness measurement online, sided corona treatment, guarantee that thickness is the 10-500 micron, each layer thickness ratio is respectively: corona layer 5%-60%, intermediate layer 5%-60%, adhesive layer 2%-40%.Then this three-layer co-extruded film is cut edge, rolling, cut, packs.

Claims

1. glass protection film; it is characterized in that: include the corona layer, intermediate layer and the adhesive layer that are bonded as one successively, its gross thickness is the 10-500 micron, and each layer thickness ratio is respectively: corona layer 5%-60%; intermediate layer 5%-60%, adhesive layer 2%-40%.
