One of main form of boundary's plastic additive application.Its advantage is: technique is simple, easy to use, it is simple to realize the production automation,
Raise labour productivity, avoid again the cleaning of environmental pollution, beneficially workers ' health to carry out production strictly in line with rules and regulations, and plastics preparation, processing,
Storage and during using, easily occur oxidation reaction and presenting to fade, yellowing, the phenomenon of cracking, its hot strength and impact are strong
The mechanical performances such as degree reduce, and most plastic not UV radiation, it is impossible to life-time service out of doors, therefore female
The antioxygenic property of grain directly affects the quality of plastic.
Summary of the invention
In view of this, it is contemplated that propose a kind of preparation method with good antioxygenic property master batch.
For reaching above-mentioned purpose, the technical scheme is that and be achieved in that: the preparation method of a kind of antioxidation master batch,
Comprise the following steps: the first step, mixing: raw material age resistor TMQ, antioxidant 2112 and antioxidant AO-60 are pressed 3:2:5's successively
Ratio carries out high-speed mixer stirring；
Second step, banburying: by the premix material feeding double screw extruder prepared in the first step or single screw extrusion machine, first
Preheating 3-5 minute, wherein each district temperature of double screw extruder is 185-230 DEG C, and the rotating speed of double screw extruder is 250-
500 revs/min；
3rd step, pelletize: in second step, the material of extrusion is cut through air-cooled flour milling and is drawn into master batch；
4th step, is dehydrated and packs.
Further, use high-speed mixer stirring, at temperature 60-80 DEG C, carry out mixed at high speed 3-5 minute, described mixed
The rotating speed of conjunction machine is 1000-2000 rev/min.
Further, also including processing aid in raw material, the total content of processing aid is 3-5wt%.
Further, the draw ratio of described single screw extrusion machine is 20-55, and the control temperature of operation is Solid Conveying and Melting respectively
District is 130-140 DEG C, 160-170 DEG C of material plasticizing district, 170-180 DEG C, melt delivery area, described single screw extrusion machine rotating speed is
300-1000 rev/min.
Further, employing aluminium foil bag encapsulation is packed described in.
The present invention has the advantage that with good effect: compared with prior art, 1, the present invention uses internally mix to add extrusion and make
Grain continuous print production technology, it efficiently solves in production process and easily builds bridge, and disperses uneven problem；2, the present invention's is anti-
Oxidation master batch can be greatly promoted the antioxygenic property of plastics, effectively promotes service life and the performance of plastics；3, possesses antioxidation
Function, effect is lasting, and has preferable stability, and cost of manufacture is relatively low.
