Description
Technical field
The present invention relates to technical field of polymer materials, and in particular to a kind of CPP films delustring masterbatch and its preparation side
Method.
Background technology
With the development of society, requirement of the people to package packing supplies is constantly updated, and packaging material is in feel, visual effect
On show aesthetic feeling, comfort and other effects.Good packaging effect can stimulate consumption of the people to product.Extinctive thin film is exactly to be
The film new varieties for meeting these requirements and developing.
Extinctive thin film is a kind of with haze low gloss, and surface can form the film for packaging of diffusing reflection extinction effect,
Its surface reflection is weak and soft.The surface gloss of Extinctive thin film is generally below 15%, and mist degree is general 50% more than, can
Its mist degree is adjusted according to packaging effect requirements.Color is true to nature etc. when Extinctive thin film has the high-end elegant, printing of comfortable feel, outward appearance
Advantage, is widely used in the products such as various high-grade packagings for foodstuff, books, Magiaine cover, propagating poster.
The production of Extinctive thin film has two ways：One kind is after film production comes out, to pass through the secondary method added, such as roller
Spend, chemical solvent corrodes, film is produced extinction effect, one of technique that this method has produced Extinctive thin film more is added and added
Work cost, and the mechanical performance of film is adversely affected；Another method is that have extinction performance by producing itself
Resin, not only the mode of production is simple for this method, will not damage the mechanical performance of film, and the soft allusion quotation of sense organ of Extinctive thin film
It is refined.
The content of the invention
The CPP film delustring masterbatch of haze low gloss can be produced it is an object of the invention to provide a kind of.
There is provided a kind of CPP films delustring masterbatch to achieve the above object, it is characterised in that by the as follows of parts by weight
Component is prepared：35-77 parts of polypropylene, 20-62 parts of polyethylene, 0.1-0.5 parts of antioxidant, 2-4 parts of filler, coupling agent 0.1-
0.5 part.
Further, prepared by the following component of parts by weight：40-65 parts of polypropylene, 35-60 parts of polyethylene, antioxygen
0.2-0.3 parts of agent, 2-3 parts of filler, 0.3-0.5 parts of coupling agent.
Further, described polypropylene is copolymerized type propene polymer, and its quality melt index is 5-20g/10min.
Further, described polyethylene is high density polyethylene (HDPE), and its quality melt index is 0.01-15g/10min.
Further, described antioxidant is at least one of model 168, AT-76, AT-10 and H3386.
Further, described filler is at least one of silica, talcum powder, calcium carbonate and di-iron trioxide.
Further, described coupling agent is in silane coupling agent, titante coupling agent, zirconate coupling agent
It is at least one.
The CPP films are with the preparation method of delustring masterbatch, according to polyethylene, antioxidant, filler, coupling agent in formula
Ratio be added sequentially in low speed batch mixer carry out mixing 3 minutes, rotating speed be 100 revs/min obtain blend；By polypropylene
With gained blend by double screw extruder extruding pelletization, the delustring masterbatch after granulation is dried 3 hours at 80 DEG C, wherein double
Screw extruder extruding and pelletizing process is, 170 DEG C -210 DEG C, 400-500 revs/min of screw speed.
The CPP films can be used for preparing CPP Extinctive thin films with delustring masterbatch.
The CPP films can be used alone as extinction layer with delustring masterbatch, can also use work with polypropene blended
For extinction layer, the CPP Extinctive thin films of preparation are provided with good extinction performance.
The principle of the invention：The generation of CPP Rough Surfaces of Thin Film, the present invention utilizes the incompatible characteristic of two kinds of resins of PP, PE,
The crystallization property of two kinds of resins produces rough surface in cooling distraction procedure.Specially：In the blown state, the viscosity of selection
The less PP and larger PE of viscosity, at this time PE is more is wrapped up by PP, and PE is dispersed in PP.Form " island " structure；Work as system
During melting extrusion, at once by compressed air or water quick cooling, during dropping at the temperature of the melt, the PP in system reaches knot earliest
Brilliant temperature, starts crystallization, so as to limit the also uncrystallized PE melts that it is wrapped；Temperature continues to decline, and reaches PE and starts
Crystallization temperature, PE crystallizations start, the huge crystallization rate due to PE with respect to PP, crystallization immediately, solidification, contraction, hardening protrusion
Polymer surfaces, so as to produce coarse surface in drawing process and roughness is quite big.Filler in the present invention is in film shape
During, filler grain part protrusion increases the uneven of film surface in film surface, so as to strengthen delustring effect
Really.
Beneficial effect of the present invention：
The present invention forms rough characteristic by the characteristic and filler of incompatible polymer in film surface, prepares
Go out a kind of CPP films delustring masterbatch.The delustring masterbatch good processability of the present invention, filer content is few, can be individually used for disappearing
Photosphere, the film prepared has the features such as haze, low-luster and heat sealability are good；It can also be used for polypropene blended
Extinction layer, the mist degree and glossiness of film are adjusted by adjusting its addition.
