Technology contents:
Problem of environmental pollution and at the scattering problem of resin when the objective of the invention is to solve superfine biological powder and directly being used for producing.
The present invention also aims to reduce product cost, improved the biomass content of plastics, and give its low-carbon environment-friendly performance.
Another object of the present invention is to disclose above-mentioned superfine biological powder filling masterbatch and preparation method thereof.
Filling master batch of the present invention mainly is made up of following different materials: vector resin, superfine biological powder, compatilizer, dispersion agent, surface treatment agent, lubricant, mineral filler, thermo-stabilizer, oxidation inhibitor and other auxiliary agent.
Carrier comprised one or more compsn such as each base polymer such as wax class, EVA, PE (comprising VLDPE, ULDPE), PP, PVC, PS, ABS, PET, TPU, PMMA, SBS, PLA, PHA, PBS, PBAT, PPC, PCL during material according to the invention constituted; Preferred base polymer PLA, PHA, PBS, PBAT, PPC, PCL one or both and the two or more mixture wherein of degrading fully, vector contg is generally 20%～70%.
Superfine biological powder during material according to the invention constitutes is that bar, leaf, fruit and the shell of natural phant is like straw powder, powdered rice hulls, wood powder and bamboo powder etc.; The shell of animal, hoof, bone, angle, hair are like feather meal, bone meal, oyster shell whiting etc.; Granularity reaches more than 300 orders, and superfine biological powder content is generally 27%～77%.
Compatilizer during material according to the invention constitutes is meant functional group's graft product of polymkeric substance; Concrete like maleic anhydride grafted polyethylene, maleic anhydride inoculated polypropylene, maleic anhydride graft PHA, maleic anhydride graft PBS etc., the content of compatilizer is generally 1%～10%.
Dispersion agent during material according to the invention constitutes is meant polyethylene wax, Poly Propylene Wax, OPE, EVA wax etc., and purpose is to improve the dispersing uniformity of ultra-fine plant powder in resin, and the content of dispersion agent is generally 1%～10%.

A kind of is that each component mixes in high-speed mixer will be filled a prescription; Mixing temperature is not higher than 60 ℃; Mixing time is about 2～8 minutes; Then the material that mixes is put into mixing plasticizing granulation under 70～150 ℃ of temperature in the twin screw extruder, the rotating speed of twin screw is controlled at PM 80～500 to be changeed.
Another kind is together to put into a component in the prescription in Banbury mixer/single screw extrusion machine; Under 70～150 ℃, plastify with mixer mixing; Mixing time was at 5～20 minutes; Adopt single screw extrusion machine at 60～130 ℃ of following extruding pelletizations then, promptly obtain Wholly-degradable primary color master batch of the present invention.
Granulation mode of the present invention can be water-cooled stretching and granulation, water ring granulation, granulation underwater or the fervent granulation of flour milling.Should carry out drying for the particle that needs water-cooled, drying temperature is 60～70 ℃, and be lower than 0.5% with moisture content time of drying is standard.
Twin screw extruder according to the invention adopts cord wood cocurrent and parallel twin screw, and the twin screw length-to-diameter ratio should not surpass 48: 1 and be advisable with greater than 28: 1, preferably selects 40: 1. in case material in screw rod, be heated for a long time and cause decomposition.
Banbury mixer/single screw extrusion machine according to the invention; Wherein Banbury mixer adopts the adding pressure type Banbury mixer, and the single screw extrusion machine length-to-diameter ratio should not be not more than 20: 1, selects get final product in 8: 1 or 10: 1; Screw rod should be adopted gradual change shape screw rod for well, shears the possibility of degrading to reduce because of material is forced.
Application example is following:
Instance one:
Prescription: (unit is kg)
The preparation method adopts the twin-screw mixer extruding pelletization, and method is following:
The high-speed mixer temperature is elevated to 110 ℃, then load weighted lime carbonate is dropped into the high-speed mixer high speed and mix, by the friction between lime carbonate and the high-speed mixer inwall;, the temperature of lime carbonate is reached more than 100 ℃, drop into the phthalate ester coupling agent that measures behind about 2～3min; Carry out high-speed stirring and mix, 110 ℃ of mixing temperatures, the treatment time is 5 minutes; And then changing the low speed cooling mixing over to, the material of handling well is emitted for use.
And then drop into the P34HB, calcium/zinc stabilizer, 1010,168, maleic anhydride graft PHA and the paraffin that have measured successively and under at a high speed, mixed one to three minute, change the low speed cooling and stirring then over to and mix, emit the good material of compounding.The material that is mixed is joined in the hopper of twin screw the mixing plasticizing extruding pelletization then through twin screw.The twin screw extruder screw slenderness ratio of selecting for use is 36: 1; Screw diameter is φ 75; The twin screw processing temperature is followed successively by 80 ℃-100 ℃-110 ℃-120 ℃-125 ℃-130 ℃-130 ℃-135 ℃-130 ℃ from feeding section to the head setting; Wherein two districts, back are head temperature, and the front is a body temperature for six sections.Screw speed is 120 rev/mins.Water ring granulation mode is adopted in granulation, carries out the drying cooling then and gets final product.
Instance two:
Above material adopts Banbury mixer/single screw extrusion machine to prepare, and concrete grammar is following:
Above material put into after good in the Banbury mixer not being higher than 150 by the prescription weighing in the lump spend under the temperature conditionss and carry out mixing plasticizing, mixing time is as the criterion with material plasticizing fully, wants to carry out more than three times exhaust during this period at least and material is overturn.Evenly also plasticizing is complete to make various material thorough mixing. and put into then and carry out granulation in the single screw extrusion machine; The single screw extrusion machine temperature is controlled at 70～130 degree and gets final product, and the particle of making is sieved just obtain superfine biological powder filling masterbatch of the present invention then.This masterbatch by a certain percentage be filled moulding (as: PHA, PBS, PLA etc.) and simply mix after, can directly be used to produce various products.
