Description
Technical field
The invention belongs to BOPP delustring technical field of membrane, it is related to the delustring material for producing BOPP matt films, and in particular to
A kind of high dispersive delustring material and preparation method thereof.
Background technology
Matt film is a kind of low gloss, haze, into the film for packaging of diffusing reflection extinction effect, the similar paper of film surface
Face, with low-down gloss, its surface reflection is weak and soft, and surface gloss is less than 15%, and mist degree is general 70%
More than, during elegant, printing quiet with comfortable feel, outward appearance color can reproduction true to nature many advantages, such as, have class paper wrapper film
Or the title of natural light glossy film.Almost most of plastics variety may be used to produce matt film, such as PA, PET, PC, PE,
PP, wherein based on polyolefin matt film, and BOPP matt films occupy very big share in the market in polyolefin.BOPP matt films
Generally ABC three-deckers composite membrane, A layers are extinction layers, and correspondence surface is referred to as delustring face, and delustering functions are provided by delustring material,
General thick 3 μm or so, the thickness of extinction layer influences very big to extinction effect, and thicker extinction effect is better, and B layers are that supporting layer is usual
Be common BOPP there is provided the mechanical performance of film, see for C layers and be actually needed, can be hot sealing layer, adherent layer, correspondence surface is referred to as
Smooth surface.
Delustring material is the PP Pipe Compound for producing BOPP matt films.Traditional delustring material is by a- polyolefin and polypropylene group
Into, the purpose of delustring is reached using the extremely low refraction index of a- polyolefin, general melt index (MFR) in 2g/10min or so,
Contain Partial Antioxidation agent.But traditional delustring material is relatively low due to MFR, along with the mobility of a- polyolefin in itself is excessively poor, when
Its with it is polypropene blended when, a- polyolefin can not be fully dispersed in polypropylene so that production matt film when, undispersed a- gather
Alkene can not be opened in stretching and cause film skin breakage, produce a large amount of bright spots, and percent defective is high, therefore, be badly in need of providing one
The delustring material in polypropylene can be fully dispersed in by planting a- polyolefin.
The content of the invention
It is an object of the invention to：Prevent a- polyolefin from being completely dispersed because MFR is relatively low for above-mentioned existing delustring material
In polypropylene, cause the problem of matt film bright spot occurs when producing, the present invention provides a kind of high dispersive delustring material and its preparation
Method.
The technical solution adopted by the present invention is as follows：
A kind of high dispersive delustring material, is made up of the raw material of following percentage by weight：A- polyolefin 50-58%, copolymerization poly- third
Alkene 40-48%, peroxide 0.3-0.8%, Organic fluoride processing aid 0.3-0.8%, antioxidant 0.8-1.5%.
The a- polyolefin is high density polyethylene (HDPE).
The peroxide is cumyl peroxide.
The Organic fluoride processing aid is fluoropolymer.
The antioxidant is antioxidant 1010.
BOPP matt films mainly realize extinction effect by film internal delustring material, and delustring material delustring comes from itself
Optical heterogeneity, and it is then refringence inside delustring material between each microcell to cause the key factor of optical heterogeneity
Different, when light enters inside the extinction layer of matt film, the optical heterogeneity inside extinction layer makes light occur multiple refraction,
Reflect each time all can cause light intensity loss with scattering, and therefore, the light appeared in incident direction will weaken significantly.It is high
Density polyethylene (HDPE) is that a kind of crystallinity is high, nonpolar thermoplastic resin, white powder granular product, nontoxic, nothing
Taste, density is in 0.940~0.976g/cm3In the range of.At present, COPP (PP) and high density polyethylene (HDPE) (HDPE) blending
System is the conventional formula system of in the market delustring material, but due to MFR relatively low (2g/10min or so), a- polyolefin can not be complete
It is scattered in polypropylene so that during production matt film, undispersed a- polyolefin can not be opened in stretching and cause film table
Face ruptures, and produces a large amount of bright spots.The present invention is by COPP (PP) and high density polyethylene (HDPE) (HDPE) co-mixing system
The mobility that peroxide improves COPP is added, and Organic fluoride processing aid is added in processing, improves a- polyolefin
Processing characteristics, eliminate or reduce die head separate out, so as to increase the melt index (MFR) of the delustring material, significantly improve a- polyenes
Dispersiveness of the hydrocarbon in COPP, that is, obtain a kind of high dispersive delustring material, thoroughly solves existing delustring material because of dispersiveness
It is bad to cause the problem of bright spot occurs in matt film surface.
A kind of preparation method of high dispersive delustring material, step is as follows：
(1) COPP is mixed with peroxide, then extruded, obtain the higher polypropylene of mobility；
(2) high-flowability polypropylene obtained by step (1) is mixed with a- polyolefin, Organic fluoride processing aid, antioxidant,
Then extrusion, pelletizing, drying, obtains high dispersive delustring material.
The mixing is carried out in high mixer, and incorporation time is 2-5min.
The extrusion uses double screw extruder, and extrusion temperature is 220-250 DEG C.
The present invention uses two step method production technology, COPP is mixed with peroxide first, improves copolymerization poly- third
The melt index of alkene, obtains the higher polypropylene of mobility, makes it when being mixed with a- polyolefin, a- polyolefin can preferably divide
Dissipate in COPP, meanwhile, addition Organic fluoride processing aid improves the processing characteristics of a- polyolefin, eliminates or reduces because altogether
The die head that poly- polypropylene melt index is improved and caused is separated out, last extruded, pelletizing, drying, obtains high dispersive delustring material.
In summary, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1. the present invention is made by adding the melt index that peroxide improves system in the co-mixing system of existing delustring material
A- polyolefin is uniformly dispersed in polypropylene, so as to obtain high dispersive delustring material, and reduces or disappears by Organic fluoride processing aid
Die head when being processed except high dispersive delustring material is separated out, and thoroughly solves existing delustring material because poor dispersion causes matt film surface
The problem of there is bright spot；
2. high dispersive delustring material of the present invention is improved due to MFR, the percentage by weight of a- polyolefin can be higher than existing delustring material
50% generally used, extinction effect is significantly improved；
3. high dispersive delustring material of the present invention is due to good dispersion, the matt film surface produced by it is consistent, glossiness one
Cause；
4. it is simple production process of the present invention, easy to operate, also, due to delustring material good dispersion, the matt film produced
Surface is substantially reduced without bright spot, percent defective, and production cost can obtain effective control.
