Description
Technical field
The invention belongs to technical field of polymer materials, particularly a kind of polymer masterbatch and preparation technology thereof and application.
Background technology
Traditional masterbatch product is grouped into primarily of following several one-tenth: matrix composition, dispersion lubricating auxiliary agent, protectiveness auxiliary agent, functional filler, wherein, functional filler is that the effective constituent of masterbatch is (such as White color masterbatch material, effective constituent is exactly the white pigments titanium dioxide contained in the middle of masterbatch), although all the other 3 kinds of components do not play direct effect in masterbatch, but be also the requisite formation of masterbatch product, matrix composition has the effect of two aspects: be that function effective components filler (particularly the functional filler of pulverulence) can be shaped on the one hand, become particle, mutually will merge with the matrix resin of follow-up use on the other hand, so just cause client and use what body material, masterbatch carrier just can only use any material, though the masterbatch product that result on market is of a great variety, but it is very strong to use limitation, inefficiencies.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of universal masterbatch product, this universal masterbatch is joined PE, PP, PS, ABS, PET, PA, all normally can use in the matrix resins such as EVA, there is excellent dispersing property, and there is lower cost, preferably economic benefit.
Universal masterbatch in the present invention calculates by weight and comprises following component: functional filler 70 ~ 90 parts, matrix composition 10 ~ 15 parts, auxiliary agent 2 ~ 4 parts,
Wherein, matrix composition is olefines synthesis macromolecule wax, molecular weight ranges 6000 ~ 10000, the product of the molecular weight 7000 that preferred Mitsui company produces,
Functional filler can be selected according to different need of productions:
When preparing colored masterbatch, functional filler chooses color stuffing, and wherein, pigment is selected from titanium dioxide, zinc sulfide white, carbon black, red, phthalocyanine blue, Victoria Green WPB or even yellowish etc., filler be selected from calcium carbonate, talcum powder, polynite, mica one or more,
When preparing opening functional master batch, functional filler chooses silicon-dioxide,
During the preparation function modified masterbatch of Hardening, functional filler gets superfine activated calcium carbonate;
Auxiliary agent comprises the protectiveness auxiliary agents such as oxidation inhibitor, thermo-stabilizer, coupling agent,
Wherein, oxidation inhibitor is four [β-(3,5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester, β-(3,5-di-tert-butyl-hydroxy phenyl) one or more in propionic acid octadecanol acid esters, 2-methylene-bis (4-methyl-6-tert-butylphenol) or three (2.4-di-tert-butyl-phenyl) phosphorous acid ester
Thermo-stabilizer is calcium zinc heat stabilizer.
Present invention also offers a kind of preparation technology of above-mentioned universal masterbatch: according to each composition weight number ratio, functional filler, matrix composition, auxiliary agent are joined in homogenizer and stir, blowing is cooled to normal temperature (25 DEG C), the mixed system of gained is joined extrusion moulding in twin screw extruder, water ring water-cooling hot cutting, centrifuge dehydration, sieving obtains universal master batch, gentle breeze is fed into feed bin, bag is filled with in metering, detect warehouse-in
Wherein, macromolecule wax can dissolve and produce certain heat in high-speed agitating process, and this heat can make the temperature of mixture be increased to about 110 DEG C,
In addition, the temperature setting in above-mentioned twin screw extruder ten districts is respectively: 90 DEG C, 120 DEG C, 145 DEG C, 165 DEG C, 165 DEG C, 175 DEG C, 175 DEG C, 160 DEG C, 160 DEG C, 150 DEG C.
Beneficial effect of the present invention is: the universal masterbatch prepared by the present invention has departed from the yoke of the tradition of " vector resin of masterbatch must match with follow-up matrix resin classification ", masterbatch of the present invention is added into PE, PP respectively, PS, ABS, PET, PA, all can normally use in the matrix resins such as EVA, and there is excellent dispersing property, masterbatch product itself without powder reuniting phenomenon, and has stronger universal performance, lower cost, preferably economic benefit.
The present invention selects olefines to synthesize the matrix composition of macromolecule wax as masterbatch, not only there is very strong versatility, and itself also possess the effect of dispersion lubrication, therefore disperseing lubricating auxiliary agent without the need to adding other again in masterbatch component, reduce cost, improve the validity of masterbatch.
Masterbatch of the present invention is in preparation process, and twin screw head pressure is low, electric current is little, and output strengthens, and judges that the lubricating coefficient of material is comparatively excellent thus, can carry the plasticizing capacity that twin screw extruder is stronger.The MFI performance number of material is 12, close with the masterbatch MFI performance number of conventional formulation.
