A kind of preparation method of anti-blue light polycarbonate membrane it is characterised in that: comprise the following steps that:
A) mechanical premixing: by Merlon powder body, anti-blue light nano-particle, compatilizer and other auxiliary agent according to proportion ingredient,
And put into full and uniform mix and blend in high speed mixer；
B) melting mixing: the mixture mixing in a) is put in double screw extruder melt blending through feeder and extrudes,
Extruder is operated under vacuum conditions, and the temperature control in each area is between 210 DEG C ~ 270 DEG C；
C) cooling and dicing: the mixture of melt blending extrusion in b) is placed in room-temperature water bath cooling, pelletizing after cooling；
D) extrusion molding: the raw particles of gained after c) cooling and dicing are transported in extruder feed bin and are timed drying, so
Afterwards extrusion system is transported to by vacuum intaking device, passes through t pattern head after fusion plastification and extrude, finally fast by format roll
Fast cooling shaping.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
The present invention a kind of anti-blue light polycarbonate membrane and preparation method thereof, technological process is simple, and production efficiency is high, low cost,
Thin film is good to the absorbent properties of blue light and ultraviolet light, and transmittance is high, for electronic product, can play protect eyes well and keep away
Exempt from by the injury of high energy shortwave blue light.
Specific embodiment
A kind of anti-blue light polycarbonate membrane of the present invention, includes: Merlon powder body 75～90 by weight
Part, 5～15 parts of anti-blue light nano-particle, 2～5 parts of compatilizer and other 2～5 parts of auxiliary agent；Described Merlon gathers for Bisphenol A Type
Carbonic ester；
Described anti-blue light nano-particle is cadmium sulfide nanoparticles, or ferric oxide nanometer particle, or tin indium oxide nanometer
Grain, or Titanium dioxide nanoparticle, or and one or more of aluminum oxide nanoparticle；The grain of described anti-blue light nano-particle
Footpath is 5～50 nanometers；Described compatilizer selects Triton X-100, or maleic anhydride grafting poe, or fatty acid polyglycol second
One or more mixture of glycol；Described other auxiliary agent is antioxidant, or Antidrip agent, or plasticizer, or releasing agent, or heat
One or more of stabilizer.
Specific embodiment 1:
Take the ferric oxide nanometer particle that 90 parts of Merlon powder body, 5 parts of particle diameters are 10 nanometers, 3 parts of maleic anhydride grafting poe, 1 part
Heat stabilizer and 1 part of antioxidant.
A kind of preparation method of anti-blue light polycarbonate membrane, comprises the following steps that:
A) mechanical premixing: take the ferric oxide nanometer particle that 85 parts of Merlon powder body, 10 parts of particle diameters are 10 nanometers, 3 parts of Malaysias
Anhydride grafting poe, 1 part of heat stabilizer and 1 part of antioxidant prepare, and put into full and uniform mix and blend in high speed mixer；Mixed
Thin film and the surface quality of thin film that the mode closed produced with the time quality directly affecting particle and by particle.The side of mixing
Formula adopt low mixed-high mixed-low mixed alternately so that base material can uniformly and effectively be mixed with various powder body and auxiliary agent and disperse.
B) melting mixing: the mixture mixing in a) is put in double screw extruder melt blending through feeder and squeezes
Go out, extruder is operated under vacuum conditions, the temperature control in each area is between 210 DEG C ~ 270 DEG C；The temperature in each area of extruder
Degree produces substantial amounts of fisheye for raw particles when producing thin film, and impact productivity ratio is relevant with product quality.Meanwhile, producing
During control the pumped vacuum systems of extruder, the purpose of evacuation is to extract the low molecular weight volatile thing in fusion plastification particle out
Matter, the presence of low molecular weight volatile material can lead to separate out on production mould surface in film manufacturing processes, a large amount of accumulate after shadow
Ring the surface quality of final thin film and thin film；
C) cooling and dicing: the mixture of melt blending extrusion in b) is placed in room-temperature water bath cooling, pelletizing after cooling；Cooling water will
The pure free from admixture of Seeking Truth.Meanwhile, in continuous flow procedure, the temperature due to cooling water can rise with the lengthening of production time
Height, too high water temperature is unfavorable for cooling down the silk molding pelletizing extracted out by extruder, therefore, in process of production it is desirable to control
The temperature of cooling water；
D) extrusion molding: the raw particles of gained after c) cooling and dicing are transported in extruder feed bin and are timed drying, so
Afterwards extrusion system is transported to by vacuum intaking device, passes through t pattern head after fusion plastification and extrude, fusion plastification temperature is
