Abstract
The utility model relates to a flame-retardant plastic packaging film. The packaging film adopts a layered structure and particularly comprises a surface layer, an intermediate layer and a bottom layer, wherein the surface layer and the bottom layer are both compression resisting layers; the intermediate layer is laminated between the surface layer and the bottom layer and is a flame-retardant layer. Matrix resin adopted by the surface layer, the intermediate layer and the bottom layer of the packaging film is polyvinyl chloride, so that the packaging film has excellent layer-to-layer bond strength; as an attapulgite rodlike structure has a certain reinforcing effect on polyvinyl chloride in the surface layer and the bottom layer, the bottom layer and the surface layer both have better mechanical property; as polyvinyl chloride has certain self-extinguishment, the flame retardant property of the packaging film is greatly improved.
Description
Technical field
The utility model belongs to field of plastic products, the plastic sheeting that designs a package, especially a kind of flame retardant type plastic film.
Background technology
At present, furniture packaging mostly is polyethylene foil, polypropylene film with plastic sheeting, and the film Combination property is better, but exist flame resistance poor, easily burning, the combustion heating amount is large, and, with phenomenons such as burning drip melts, be easy to cause this large defect of fire, and price is relatively high.Therefore, fire-retardant requirement is one of Essential Performance Requirements of plastic packaging film.
In flame retardant plastics film flame-retardant system, halogenated flame retardant has high flame retardant, but its amount of being fuming is large, and the hydrogen halide discharged has severe corrosive and hiding secondary harm.In halogen-free flame retardants, Al (OH)
3And Mg (OH)
2Addition large, have a strong impact on mechanical property and the processing characteristics of film, by Mg (OH)
2The fire-retardant film of preparation is absorbing CO
2Easily make afterwards product surface " frosting ", hickie occurs or tarnish etc.; Phosphorus flame retardant can produce a large amount of flue gases in fire, and larger limitation is arranged, and in some airtight occasions or important place, can not adopt; Silicone flame retardant is not used widely because price is too high yet; The flame retardance of single nanometer system is still not good enough.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of intensity flame retardant type plastic film of anchoring strength between laminar texture and its interlayer structure higher level preferably that has is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of flame retardant type plastic film, this film is laminar texture, specifically is divided into surface layer, interlayer and bottom, and surface layer and bottom are the resistance to compression layer, and between surface layer and bottom, pressing has interlayer, and this interlayer is flame-retardant layer.
And described surface layer and bottom adopt the synthetic material of attapulgite and expanding halide-free fire-retardant complex material and polyvinylchloride.
And described interlayer is made by Vinyl chloride resin.
Advantage of the present utility model and good effect are:
1, the matrix resin that in the utility model, surface layer, interlayer and bottom adopt is polyvinylchloride, therefore this packing film has good interfacial bonding strength, because the club shaped structure of attapulgite has certain enhancing effect to the polyvinylchloride in surface layer and bottom, therefore bottom and surface layer all have mechanical property preferably, and polyvinylchloride itself has certain flame resistance, therefore this packing film flame retardance is greatly improved.
What 2, in the utility model, surface layer and bottom adopted is the composite flame-retardant system of attapulgite and expanding halide-free fire-retardant, expansion type flame retardant and attapulgite are composite, can play fire-retardant coordinative role on the one hand, can effectively prevent the characteristics such as poly-mer molten drop, attapulgite is cheap on the other hand, can reduce fire-retardant cost.
The accompanying drawing explanation
Fig. 1 is this antibacterial food plastic film for wrapping laminar texture enlarged diagram.
The specific embodiment
Below in conjunction with accompanying drawing, this is further illustrated the utility model, following embodiment is illustrative, is not determinate, can not limit protection domain of the present utility model with following embodiment.
A kind of flame retardant type plastic film, this film is laminar texture, specifically is divided into surface layer 1, interlayer 2 and bottom 3, and surface layer and bottom are the resistance to compression flame-retardant layer, and between surface layer and bottom, pressing has interlayer, and this interlayer is flame-retardant layer.
Above-mentioned surface layer and bottom adopt the synthetic material of attapulgite and expanding halide-free fire-retardant complex material and polyvinylchloride, and interlayer is made by Vinyl chloride resin.Because the club shaped structure of attapulgite has certain enhancing effect to the polyvinylchloride in surface layer and bottom, therefore bottom and surface layer all have mechanical property preferably, and polyvinylchloride itself has certain flame resistance, therefore this packing film flame retardance is greatly improved.
Claims (2)
1. a flame retardant type plastic film, it is characterized in that: this film is laminar texture, specifically is divided into surface layer, interlayer and bottom, and surface layer and bottom are the resistance to compression layer, and between surface layer and bottom, pressing has interlayer, this interlayer is flame-retardant layer.
2. flame retardant type plastic film according to claim 1, it is characterized in that: described interlayer is made by Vinyl chloride resin.
