Content of the invention
The technical problem to be solved be provide a kind of prevent fish-eye shaped bubble,
And aging pet master batch of pet and preparation method thereof can be prevented to a certain extent.
For solving above-mentioned technical problem, technical scheme is as follows:
A kind of pet master batch, it is by carrier, colouring agent, lubricant, anti-blocking agent, nucleation
Agent, antioxidant and dehydrating agent composition；Wherein each component percetage by weight is: carrier: 70%～
82%th, colouring agent: 1%～5%, lubricant: 0.5%～1.5%, anti-blocking agent: 5%～8%,
Nucleator: 9%～11%, antioxidant: 0.5%～1.5%, dehydrating agent 1.5%～2.5%.
Further, described carrier is pet resin.
Further, described colouring agent be titanium dioxide, cadmium red, chrome yellow, zinc powder, three oxidation two
One of iron.
Further, described lubricant is atoleine (Chinese wax), microcrystalline wax, polyethylene
One of wax.
Further, described anti-blocking agent is in synthetic silica or gas-phase silica
Kind.
Further, described nucleator is one of polyolefin elastomer poe, Sodium Benzoate.
Further, described antioxidant is pentaerythritol ester, thio-2 acid dibasic acid esters, or
The mixture of the two.
A kind of preparation method of pet master batch, comprises the following steps:
Above-mentioned material is prepared in proportion compound；
The compound preparing is added high-speed mixer, mixer rotating speed controls 760～1400
Rev/min, incorporation time is 8～20 minutes, and mixing temperature is maintained at 95～170 degrees Celsius；
Again well-mixed material is entered melt blending in dual-screw-stem machine, melt temperature controls
260～270 degrees Celsius, screw speed is 150～400 revs/min；
Obtain pet of the present invention after the shearing of screw rod, mixing, granulation, drying
Master batch.
The positive effect of the present invention: in technical solution of the present invention, add appropriate dehydrating agent,
Prevent pet from flake phenomenon occurring, make that thin film strength is higher, CABLE MATERIALS insulating properties more
Good, also make that product surface is smooth, transparency is high, improve the physical property of pet product；
Meanwhile, prevent pet aging to a certain extent, make the service life of pet longer, physics
Characteristic is more preferably.
Specific embodiment
In order that the object, technical solutions and advantages of the present invention become more apparent, with reference to
Specific embodiment and embodiment, are described in further details to the present invention.Here, the present invention
Exemplary embodiment and its illustrate for explaining the present invention, but be not intended as to the present invention's
Limit, any implication suitable with the claims in the present invention and scope are all considered as being included in weighing
In the range of sharp claim.
With reference to embodiment, the present invention will be further explained:
Embodiment 1
At normal temperatures and pressures, by the component pet resin of following weight percentage: 70%, titanium white
Powder: 1%, Chinese wax: 0.5%, gas-phase silica: 5%, polyolefin elastomer poe:9%,
Pentaerythritol ester: after 0.5%, dehydrating agent 1.5% mixes, mixture is put into rotating speed and exists
760 revs/min, mixing temperature be maintained in 95 degrees Celsius of high-speed mixer, incorporation time
For 20 minutes；Then by mixed material put into again melt temperature be 260 degrees Celsius,
Screw speed carries out shearing, kneads for 150 revs/min of double screw extruders, after made again
Grain, it is dried to obtain the pet master batch of the present invention.
Embodiment 2
At normal temperatures and pressures, by the component pet resin of following weight percentage: 82%, three oxygen
Change two iron: 5%, microcrystalline wax: 1.5%, silica: 8%, Sodium Benzoate: 11%,
