Abstract
The present invention relates to a kind of two-way stretching polyamide（BOPA）Pearl film and preparation method thereof, described two-way stretching polyamide (BOPA) pearl film are by melting the three-decker composite membrane being made up of top layer 1, pearl layer and top layer 2 formed after co-extrusion, slab, biaxial tension, thermal finalization；Wherein, described top layer 1 and top layer 2 are made up of by mass fraction following raw material：0~1 part of antiblocking agent, 0~1 part of slipping agent, 90~100 parts of polyamide；Described pearl layer is made up of by mass fraction following raw material：1~10 part of pearl essence, 0.01~1 part of dispersant, 90~100 parts of polyamide.Two-way stretching polyamide (BOPA) pearl film that the present invention is prepared has the characteristics that intensity height, the pearl effect that density is small, process is simple, good, both the visual demand of people had been met, cost is reduced again, has filled up the blank of two-way stretching polyamide (BOPA) pearl film.
Description
Technical field
The present invention relates to technical field of polymer materials, and in particular to a kind of two-way stretching polyamide (BOPA) pearl film and
Its preparation method.
Background technology
BOPA is the abbreviation of two-way stretching polyamide film, and BOPA is in addition to possessing the common trait of general film, also
With extremely wide temperature in use, there is high barrier, extremely excellent punctured resistance, excellent to various common gas smells and grease
Good wearability, acid and alkali resistance, grease and various it common are solvent.Therefore, it is widely used in ordinary food packing timber
Material, non-food stuff packaging material；Boiling packaging material and the high-grade packaging material such as stamping systems and metallized thread, heat-resisting seperation film
Field.
The pearl film of White-opalescent has the texture as silks and satins, and soft pleasing pearly luster, low-density, good is flat
Whole property, barrier properties for gases, particularly suitable for the high-end market of packaging field, while it or a kind of good base lining, carrying out
Full version bottoming can need not be carried out during surface printing, there are good market prospects.
However, in existing biaxial tension pearl film, the production of Biaxially oriented polypropylene (BOPP) pearl film is all related to
And preparation method thereof.Therefore, still need to seek a kind of two-way stretching polyamide of dependable performance (BOPA) pearl film and its preparation side
Method, done one's bit for the development of pearl film.
The content of the invention
It is an object of the invention to make up the vacancy of prior art, there is provided a kind of two-way stretching polyamide (BOPA) pearly-lustre
Film, BOPA pearl films prepared by the present invention have pearly luster obvious, and density is low, and excellent in mechanical performance, barrier properties for gases are excellent
The characteristics of.
Another object of the present invention is to provide above-mentioned two-way stretching polyamide (BOPA) preparation method of pearl film.
To meet above-mentioned purpose, the present invention adopts the following technical scheme that：
A kind of two-way stretching polyamide (BOPA) pearl film, two-way stretching polyamide (BOPA) pearl film is by top layer
1st, the three-decker composite membrane that pearl layer and top layer 2 form；
Wherein, described top layer 1 is made up of by mass fraction following raw material：0~1 part of antiblocking agent, 0~1 part of slipping agent,
90~100 parts of polyamide；Described pearl layer is made up of by mass fraction following raw material：1~10 part of pearl essence, dispersant
0.01~1 part, 90~100 parts of polyamide；Described top layer 2 is made up of by mass fraction following raw material：Antiblocking agent 0~
1 part, 0~1 part of slipping agent, 90~100 parts of polyamide.
Preferably, the top layer 1 of two-way stretching polyamide (BOPA) pearl film is made up of by mass fraction following raw material：
0.5 part of antiblocking agent, 0.8 part of slipping agent, 98.7 parts of polyamide；Pearl layer is made up of by mass fraction following raw material：Pearl
5 parts of light powder, 0.05 part of dispersant, 94.95 parts of polyamide；Top layer 2 is made up of by mass fraction following raw material：Antiblocking agent
0.5 part, 0.8 part of slipping agent, 98.7 parts of polyamide.
The mechanism that BOPA pearl films of the present invention produce pearl effect is due to pearl essence and polyamide in pearl layer
Resin-bonding power is low, and in drawing process, rigid pearl essence particle can not be orientated with polyamide molecule deformation of chain, so as to formed with
Space centered on pearly-lustre powder.Light irradiates space, interferes phenomenon, multi-level interference, produces pearl effect.Cause
This, in the present invention, the particle size of pearl essence is particularly important, and particle diameter is too small, and stretching space benefit diminishes, mist degree increase, pearl
Light effect reduces, and particle diameter is excessive, stress concentration, easily forms defect, causes mechanical property to be greatly lowered, while pearl effect
Step-down.Therefore the particle diameter of the pearl essence is between 1~10 μm；Preferably, the particle diameter of the pearl essence is 3~8 μm.
Preferably, the void size in the BOPA pearl films between pearl essence and polyamide is 10nm~50nm.
