Abstract
This utility model discloses a kind of uvioresistant, heat-resisting BOPET films, and it is followed successively by basement membrane, graphene layer, ultraviolet resistant layer and organic silica refractory coating with BOPET film as basement membrane, from the bottom to top.Compared with existing BOPET films, BOPET films of the present utility model have good being heated evenly property, can prevent hot-spot, can absorb shielding ultraviolet rays, and do not reduce film clarity.
Description
Technical field
This utility model belongs to film applications, and in particular to a kind of uvioresistant, heat-resisting BOPET films.
Background technology
BOPET film（That is biaxially oriented polyester film）With intensity it is high, rigidity is good, transparent, glossiness is high the features such as；
Particularly odorless, tasteless, colourless, nontoxic, prominent obdurability, and be widely used in automobile, household, electronic product
In protecting film.But find in actual applications in common BOPET film heat shrink fire-retardant fireproof and uvioresistant performance and bad.
Patent 203305606U discloses a kind of heat resistant fire-proof plate BOPET protecting film, and its BOPET films surface has one layer
Organic silica refractory coating, with good flame-proof heat-resistant performance, but does not have anti-ultraviolet function.
Utility model content
This utility model is intended to be improved above-mentioned heat resistant fire-proof plate BOPET protecting film, improves the resistance to of BOPET film
Hot and anti-ultraviolet property.
This utility model realizes that the technical scheme adopted by above-mentioned purpose is as follows：
A kind of uvioresistant, heat-resisting BOPET films, it is followed successively by basement membrane, Graphene with BOPET film as basement membrane, from the bottom to top
Layer, ultraviolet resistant layer and organic silica refractory coating.
Further, the BOPET film thickness is 25～150 μm.
Further, the graphene layer is with 1～10 layer of Graphene.
Further, the ultraviolet resistant layer thickness is 10～20 μm.
Further, organic silica refractory coating thickness is 2～5 μm.
Beneficial effect：This utility model increases graphene layer between organic silica refractory coating and basement membrane, can improve
Being heated evenly property of thin film, prevents hot-spot, so as to improve the heat resistance of thin film.Ultraviolet resistant layer adopts the anti-purple of light absorbs type
Outside line agent, the alternative ultraviolet that absorbs are converted into harmless low-energy radiation, and graphene layer can play auxiliary shield ultraviolet
Effect, reach, and do not reduce the effect of film clarity.
Description of the drawings
Fig. 1 be uvioresistant, the schematic diagram of heat-resisting BOPET films, wherein, 1-BOPET thin film, 2- graphene layers, 3- UV resistance
Line layer, the organic silica refractory coatings of 4-.
