Description
One, technical field:
The present invention relates to a kind of masterbatch and preparation method thereof, particularly relate to a kind of mother filler of black plastic and preparation method thereof.
Two, background technology:
Usually in the plastic working process auxiliary agent that adds, weighting agent etc. are concentrated in and make filling master batch in the vector resin, it has the following advantages: be easy to metered charge and blend operation, purify Working environment etc.
With the polyolefin packing material of lime carbonate as weighting agent, the main purpose of adding in plastics is when guaranteeing the material excellent machinability, interpolation that can maximum, filling master batch with cheapness substitutes expensive polyolefine raw material, reduce production costs to reach, improve the purpose of performance.
The plastic filler of China mainly contains two kinds of Atactic Polypropelene and polyethylene from the selection of vector resin.The addition of Atactic Polypropelene is little, and prepared product properties descends more, and stability is relatively poor with storage property.Though and polyethylene has overcome the part shortcoming of Atactic Polypropelene, the addition of masterbatch is limited, and the mechanical property of goods is not significantly improved, even also has and descend.Properties-correcting agent and processing aid also have bigger influence to the performance of masterbatch, and the adding of processing aid is risen the cost of filling master batch, and the adding of lower molecular weight auxiliary agent further reduces the performance of goods; Properties-correcting agent adopts lipid acid and its esters, and cost is lower, but treatment effect is not ideal enough, and utilize aluminium separately, coupling agents such as titanium, boron, silane, effective, but cost is higher, and complex process.Can only be used for processing as this plastic filler, can't realize blending and modifying processing, significant limitation be arranged in application facet with engineering plastics with the blend of polyolefin plastics.
It generally all is to be processed into black plastic products together after adopting plastics and black masterbatch and filling master batch three to mix that traditional plastics will be coloured to black.Because the material cost of black masterbatch than higher, causes the manufacturing cost of black plastic products to raise.
Three, summary of the invention:
The objective of the invention is to solve traditional filling master batch should add filling master batch and add black masterbatch again when being used to process black plastic, cause the goods cost to raise, degradation, and can not be applied to the problem in engineering plastics field, a kind of mother filler of black plastic is disclosed, make when the processing black plastic, to need not to add in addition black masterbatch and traditional filling master batch, and can be applied to the engineering plastics field, reduce the manufacturing cost of black plastic.
The present invention is achieved in that mother filler of black plastic, it is characterized in that comprising following each component, in weight part: 25～63 parts of calcium carbonate superfine powders, 10～30 parts of carbon blacks, 7.5～25 parts of styrene-butadiene-styrene copolymer 1s, 1～4 part of naphthenic oil, 5.5～15 parts of oxidized polyethlene wax, 1～5 part of ethylene bis stearic acid amide.The median size of described calcium carbonate superfine powder is 5～10 microns.Described sooty median size is 15～40 microns.Its preparation method is made of following steps: (1) is at first oil-filled softening in stirrer styrene-butadiene-styrene multipolymer and naphthenic oil, becomes behind the softening body of styrene-butadiene-styrene multipolymer stand-by; (2) calcium carbonate superfine powder and carbon black, oxidized polyethlene wax are put into the stirring mixing roll, when whisking temperature of charge to 120 ℃～130 ℃, the softening body restir of adding ethylene bis stearic acid amide, styrene-butadiene-styrene multipolymer 1～3 minute is made premix; (3) premix is put into parallel dual-screw tablets press granulation, fervent, cooling packing is promptly made mother filler of black plastic.
The technical characterstic of mother filler of black plastic of the present invention:
(1) median size is that 5～10 microns calcium carbonate superfine powder has the inorganic rigid particle toughening effect.
(2) the present invention coats with coupling agent to handle, but with oxidized polyethlene wax the calcium carbonate superfine powder surface treatment is coated, thereby has increased the consistency of calcium carbonate superfine powder with Plastic Resin, and reduces cost greatly.
When (3) adopting the styrene-butadiene-styrene multipolymer mother filler of black plastic to be added to make goods in the plastics, has good consistency and toughness as vector resin.
(4) ethylene bis stearic acid amide has good dispersiveness to carbon black, and itself has good lubricity, and is little to wear and tear in machines.
(5) because the styrene-butadiene-styrene multipolymer is the rubber-like solid matter, adopt naphthenic oil to become softening body for it is oil-filled, its purpose is exactly to improve the processing fluidity of styrene-butadiene-styrene multipolymer, reduction viscosity.
The present invention compared with prior art has following advantage:
1, the mother filler of black plastic Application Areas is extensive, can be applied to general-purpose plastics and can be applied to engineering plastics again, is different from traditional filling master batch and can only be used for the general-purpose plastics field.Traditional filling master batch is because the vector resin that adopts is a polyolefin resin, can only be used for the general-purpose plastics field, and mother filler of black plastic adopts the styrene-butadiene-styrene multipolymer can use at general-purpose plastics and engineering plastics field as solid support material.
2, reduced the cost of producing black plastic, and quality product there has been assurance.It generally all is to be processed into black plastic products together after adopting plastics and black masterbatch and filling master batch three to mix that traditional plastics will be coloured to black.Because the material cost of black masterbatch than higher, causes the manufacturing cost of black plastic products to raise.The vector resin of black masterbatch the inside and the compatibility problem of plastics also will be considered in addition, cause consistency bad easily, influence quality of item.And mother filler of black plastic has replaced black masterbatch with carbon black, and the styrene-butadiene-styrene multipolymer wherein and the consistency of various plastics are all relatively good, thereby make the quality of black plastic products that assurance arranged.
