Further, the solubilized modifying agent is one or more of mixtures in EVA, nano-calcium carbonate.
Further, the processing accelerator is that polyethylene glycol, polyester analog assistant, the one or more of fluorine-containing analog assistant are mixed Compound.
The PE white master batch of the present invention uses twin-screw extrusion unit granulation preparation, including step：
(1) white powder, partially modified solubilizer are mixed into 4-8 minutes with inorganic agent with 300-700 revs/min of speed, It is preferred that 400 revs/min；
(2) modified and solubilized dose 300-700 revs/min of the speed mixing 2-10 minutes of carrier and remainder are added；
(3) it is eventually adding 300-700 revs/min of progress mixed at high speed 10-20 minute of stabilizer and processing accelerator；
(4) mixture obtained by (3) is poured into double screw extruder and carries out melting extrusion, then carry out tie rod pelletizing, drying Produced with packaging.
Further, step (1) uses modified and solubilized dose of amount using modified and solubilized dose of amount more than step (2), Specific allocation proportion can be to meet any proportion that step (1) usage amount is more than under the conditions of step (2) usage amount.
The PE white master batch of the present invention can also use banburying unit to be granulated；Concrete operations include：Put after each component is mixed Enter banburying unit banburying 30min；It is subsequently poured into double screw extruder and carries out melting extrusion, is by the shearing and mixing of twin-screw White powder fine dispersion in vector resin, tie rod pelletizing, drying and packaging are then carried out, the white master batch of the present invention is made.
Further, the processing conditions of double screw extruder melting extrusion is in above-mentioned steps (4)：The temperature setting of one area 150-175 DEG C, two area's temperature set 160-175 DEG C, and three area's temperature set 170-175 DEG C, and four area's temperature set 170-175 DEG C, Five area's temperature set 170-175 DEG C, and six area's temperature set 170-175 DEG C, and seven area's temperature set 170-175 DEG C, and eight area's temperature are set Determine 150-170 DEG C, nine area's temperature set 150-170 DEG C, 300-400 revs/min of engine speed.
Beneficial effect of the present invention：
Using inorganic agent component, preferentially heating melts and is coated on white powder particles surface the present invention in process, from And play the resistant to elevated temperatures effect for improving white powder particles；And confirmed by practical production experience, instant component proportioning and life The covered effect of inorganic agent is optimal during production condition.
Compared with prior art, white master batch provided by the invention defends material curtain coating level film production manufacture coloring applied to PE When, PE can be realized to defend under hot environment of the material curtain coating level film more than 320 DEG C life is cast with 200 meters per minute of high speed Production, and can ensured sustained development high temperature and high speed steady production；White Pigment Dispersion is excellent, no color differnece, without transparent lines；It is of the invention big Amplitude improves labor productivity, improves film yield, has saved electric power energy consumption and has reduced production cost, technique effect shows Write.
