Abstract
The invention discloses an anti-fog transparent PET color masterbatch which is characterized in that: the color masterbatch is prepared from components of, by weight: 65 to 85% of a carrier, 0.1 to 10% of a toner, 0.1 to 3% of a dispersant, 0.1 to 2% of a processing auxiliary agent, and 12 to 20% of a nucleating agent. The invention also discloses a preparation method of the anti-fog transparent PET color masterbatch. The anti-fog transparent PET color masterbatch provided by the invention is characterized by short molding period and smooth product surfaces. During an injection molding process, a white fog phenomenon is prevented from occurring.
Description
Technical field
The present invention relates to technical field of polymer materials, particularly a kind of antifog clear PET (polyethylene terephthalate) Masterbatch and preparation method thereof.
Background technology
PET (polyethylene terephthalate) has high rigidity and intensity as using the widest engineering plastics, good thermotolerance, and chemical proofing and electrical insulating property are widely used in fiber, film and carafe field.But because its slower crystallization rate; Cause crystallization imperfection and inhomogeneous, cause prolong molding cycle, more serious is to cause the coarse tarnish of product surface; Especially when being processed into bottle embryo; Be easy to produce a kind of white mist phenomenon and opaque, this has just proposed very high requirement to processing condition in the injection moulding process and equipment, and some producers that produce the bottle embryo are caused technical inconvenience.
Summary of the invention
The present invention is directed to the above-mentioned deficiency of prior art, provide a kind of molding cycle short, product surface is smooth, and in injection moulding process, can not produce the antifog clear PET Masterbatch of white mist phenomenon.
In order to solve the problems of the technologies described above; Technical scheme of the present invention is: a kind of antifog clear PET Masterbatch, this Masterbatch is prepared by each component of following weight percent: carrier 65 ~ 85%, toner 0.1 ~ 10%, dispersion agent 0.1 ~ 3%, processing aid 0.1 ~ 2%, nucleator 12 ~ 20%.
Above-mentioned carrier is a polyethylene terephthalate.
Above-mentioned toner is various transparency dyes, like solvent blue 97, and Oil Yellow 93, solvent red 52 etc.
Above-mentioned dispersion agent is a kind of polar waxes, like CERALENE694, and CERALENE693, CERALENE691 etc.
Above-mentioned processing aid is a turps, can make dyestuff and carrier well compatible.
Above-mentioned nucleator is a kind of polymer ionomer, can be the SURLYN series ionomer of E.I.Du Pont Company's research and development, and like SURLYN8920, SURLYN8940 can.
Another technical problem that the present invention will solve provides the preparation method of above-mentioned antifog clear PET Masterbatch, and preparation process is:
(1) each component was mixed in high-speed mixer 1 ~ 2 minute by formula rate batching back;
(2) adopt screw extrusion press to carry out melt blending and extruding pelletization then, the temperature of this process control screw extrusion press is 220 ~ 260 ℃, and the rotating speed of screw extrusion press is 280 ~ 320r/min, obtains antifog clear PET Masterbatch.
Screw extrusion press of the present invention is twin screw extruder or single screw extrusion machine.
Advantage of the present invention and beneficial effect:
Antifog clear PET master batch of the present invention has improved the PET crystalline-granular texture; Improve crystallization rate; Enhance mechanical properties shortens shaping cycle, has solved the white mist phenomenon that produces because of the Technology problem in the PET bottle embryo injection moulding process to a great extent; Greatly reduce in bottle embryo making processes requirement, and have certain generalization in PET injection moulding field to processing condition and equipment.
