Description
Technical field
The present invention relates to functional high molecule material field, more particularly to a kind of compound delustring masterbatch of BOPA films
Preparation technology.
Background technology
BOPA is BON biaxially oriented nylon film（Biaxially oriented polyamide (nylon) film）English
Literary abbreviation BON biaxially oriented nylon film（BOPA）The important materials for producing various compound package materials, at present turn into after BOPP,
The third-largest packaging material after BOPET film, BON biaxially oriented nylon film abbreviation BOPA films, its main raw material(s) is poly-
Caprolactam, abbreviation nylon 6 or PA6, this raw material is passed through fusion extrusion casting on special equipment, then carry out longitudinal direction, horizontal stroke
To（Or simultaneously）Film, i.e. BON biaxially oriented nylon film is made in stretching.It is outstanding tensile strength and punctured resistance, excellent
To the high barrier of gas and smell, the anti-chemical of grease-proof oxycarbide, wider Applicable temperature scope（-60℃∽150
℃）, the good transparency and glossiness, good printing, can be widely used for numerous areas, especially packaging, ornament materials
Etc..But with the change of people's aesthetic standards, the requirement to package packing supplies is constantly updated, and is in package material surface feature
Existing diversity requirements, to be stimulated from many-sided reaction packing article such as aesthetics, restocking effect, advertising and performance manufacturer
The special-effect of consumer's sense organ vision.Then under this requirement, delustring polyester film is developed and had extensive
Using.Usually said delustring polyamide film is the film of a kind of low gloss, haze, need to typically meet mist degree> 50%、
Glossiness< 40%.
The most frequently used method of the manufacture of delustring polyamide film at present：, delustring material is coated generally by way of coating
On the top layer of common BOPA light film, this needs the production of common BOPA light film and delustring material is coated into BOPA on coating machine
Two step on film.Unstable product quality, yield poorly, process is cumbersome, cost is high, and its delustering agent effective content is limited by technique
System can not be too high, and the product of existing market is up to 30000ppm（3%）, therefore do not reach low-luster polyamide film（Light
Damp degree is less than 10）Requirement, can be only used for produce normal dull PA membrane.
It is in summary, domestic that there has been no high content and the special high content delustring masterbatch of cost-effective BOPA films.
The content of the invention
It is an object of the present invention to lacking for the smooth performance of film and optical property can not be taken into account by solving conventional delustring masterbatch
Point, there is provided a kind of BOPA films compound delustring masterbatch and its preparation technology.By preferred delustering agent, solves technology hardly possible
Topic.Meanwhile be formulated in design, high content delustering agent accounting, client's usage amount, effective control cost can be reduced.
To achieve the above object, using following scheme：

Meet coupling agent using coupling agent A151, coupling agent A172 to be modified polyamide surface, enhance polyamide
With the compatibility of compound delustering agent so that high content（10% and more than）The preparation of delustring masterbatch be possibly realized.Delustering agent is adopted
Formed with poly(4-methyl-1-pentene) and polycarbonate compounding, it is preferred that poly(4-methyl-1-pentene) and polycarbonate
Weight ratio be 7:6, because under this ratio, poly(4-methyl-1-pentene) is with polycarbonate in polyamide
Synergy reaches most strong, and extinction effect is best.
One kind prepares the compound delustring masterbatch of above-mentioned BOPA films, comprises the following steps：Carrier polyamide is used into electricity
The sub accurate weightless main spout for claiming extruded machine adds, and fully heating melting is fine by poly(4-methyl-1-pentene), makrolon
After dimension, coupling agent A151, coupling agent A172, primary antioxidant 1076, auxiliary anti-oxidant 264 mix in proportion, lost by precision
Claim to be added by side spout again, side spout is located at the second section heat block at die head rear, and both are abundant through double screw extruder
After melt blending, by melt extrusion, extruder produces temperature control in 200-250 DEG C, current control in 440-460A, extruder
Revolution control in 420-430r/min, each heating interval temperature control after 200-260 DEG C, melt extrusion through underwater cutpellet, it is cold
But masterbatch finished product is made after, drying.
By way of the feeding of side, claim through high-precision electronic is weightless to add compound auxiliary, and using high density filter screen and
The technological designs such as whole course net pressure monitoring, efficiently solve the difficult production technology key technical problem of high content formula dispersiveness.It is real
Border application attestation, the product succeeded in developing have extraordinary dispersiveness.
Of the invention there should be advantages below：The present invention will combine delustring principle, modified theoretical and the market demand, design are opened
Send out BOPA functional films very high content delustring masterbatch a kind of and realize its marketization and industrialization.The present invention will break through existing
The production technology of delustring masterbatch, coating method after substitution is pioneering to select double screw extruder, is matched somebody with somebody using selected delustering agent and uniqueness
Side and the method for molten polyamide blending, extruding pelletization prepare the special delustring masterbatch of BOPA films.Prepared using the delustring masterbatch
Polyester film there is low-luster, haze, high transmission rate, good smoothness and excellent aluminize with printing performance etc..
In addition, this Project Product can realize the adjustable glossiness of BOPA Extinctive thin films and mist degree, Ke Huke by different additions
According to different application, multi-level, differentiation BOPA matt film is produced, not only realizes product diversification, and saved cost, more
Be advantageous to environmental protection.
