The one side of biaxially oriented polypropylene film layer, described adhesive-layer is coated in the another side of described biaxially oriented polypropylene film layer.This reality
With new halogen-free flameproof film, the fire prevention particle that BOPP film is added in producing is few, does not affect the shaping of film and physical
Can, there is certain fire line simultaneously.By the process of enhancement layer of preventing fires, BOPP film can be made to be fully achieved VTM-0 level, reach
The fire protecting performance of high request.Cost more than 30% can be substantially reduced in the field of packaging and label for fire prevention PET, PI relatively.
Fully achieve halogen-free, environmental friendliness.
Brief description
Fig. 1 is structural representation of the present utility model.
Specific embodiment
With reference to specific embodiment, technical solutions of the utility model are further illustrated.
As shown in figure 1, specific embodiment of the present utility model is：Build a kind of halogen-free flameproof film, include successively using
In strengthen fire-retardant fire-retardant enhancement layer 1, biaxially oriented polypropylene film layer 2, have cold mount or adhesive-layer 3 that heat is compound, described resistance
Combustion enhancement layer 1 is coated in the one side of described biaxially oriented polypropylene film layer 2, and described adhesive-layer 3 is coated in described biaxial tension and gathers
The another side of propylene film layer 2.
As shown in figure 1, specific implementation process of the present utility model is：Fire-retardant enhancement layer 1 has certain thickness and adds
Plus the resin bed of powder flame-proof agent, the flame retardant rating due to increasing the biaxially oriented polypropylene film of 10%-20% does not reach will
Ask it is necessary to be further added by one layer of fire-retardant enhancement layer to reach flame retardant rating come the anti-flammability to lift biaxially oriented polypropylene film.By polyester
One or more of resin, polyurethane resin, acrylic resin, organic siliconresin mixed with resin powder flame-proof dosage form becomes mixing
Thing, is coated in the one side of biaxially oriented polypropylene film layer 2.Using fire retardant be：Generally phosphorus system or with the resistance of other powder
Combustion agent, the thickness range of fire-retardant enhancement layer 1 is 5 μm to 15 μm.Biaxially oriented polypropylene film is to pass through film using plastic pellet
Two-way the drawing high of production equipment completes, and adds a certain proportion of fire retardant, the powder flame-proof agent of interpolation in pp plastic pellet simultaneously
Add generally phosphorus system or the mixing composition with other powder flame-proof agent, the 10%-20% of adding proportion opposed plastic particle.
Add the certain fire resistance of lifting of fire retardant, current technology can not directly the ratio by increasing fire retardant realize fire-retardant,
If adding excessive, being difficult to plastic pellet and being difficult to film forming, and reducing the physics tensile property of film, therefore can be by again
Fire-retardant reinforcement is realizing anti-flammability.The thickness range of described biaxially oriented polypropylene film layer is 10 μm to 50 μm.Adhesive-layer 3 has
Cold mount or performance that heat is compound, by one of resin of acrylic resin, polyester resin, polyurethane resin or rubber series or many
