Abstract
The invention provides a uniformly disperse foaming agent masterbatch. The uniformly disperse foaming agent masterbatch is prepared by mixing ADCA, polyolefin resin, a dispersing agent, an antioxidant and a stabilizing agent. The invention also provides a preparation method of the uniformly disperse foaming agent masterbatch. The uniformly disperse foaming agent masterbatch is prepared by a double dispersion method. The technical scheme ensures the degree of mixing uniformity of the foaming agent powder and the polyolefin resin granules. By using the double dispersion method, the powder and the granules are mixed more uniformly and the foaming agent masterbatch has stable quality.
Description
Technical field
The present invention relates to field of plastic products, be specifically related to a kind of whipping agent field.
Background technology
Blowing agent concentrate in a large number in general-purpose plastics, engineering plastics, have alleviate finished weight, improve finished product rigidity, prevent shrinkage cavity with distortion, improve the effects such as final dimension precision.
The quality, processing mode, complete processing etc. of whipping agent master batch all directly affect the quality of foam plastic product, development of modern industry has had higher requirement to the performance of high quality plastic master batch and processing technology, as required better dispersiveness, whipping agent master batch that quality is more stable.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, improving some performances of prior art, as better dispersed, more stable quality, foam material abscess homogeneity control etc.
For achieving the above object, technical scheme of the present invention is, a kind of dispersed whipping agent master batch, and its formula is as follows:
ADCA 60%-69.5%；
Polyolefin resin 30%-40%;
Dispersion agent 0.2%-1%;
Oxidation inhibitor 0.1%-1%;
Tranquilizer 0.2%-1%.
Preferably, described dispersed whipping agent formula of master batch is as follows:
ADCA 65%；
Polyolefin resin 32%;
Dispersion agent 1%;
Oxidation inhibitor 1%;
Tranquilizer 1%.
Preferably, described dispersion agent is Zinic stearas, calcium stearate or its mixture.
Preferably, described oxidation inhibitor is antioxidant 1010,168,264 or its any mixture.
Preferably, described tranquilizer be 626,618, TP-10 or its any mixture.
Preferably, described polyolefin resin is PE, and its melting index is 25 g/10min.
The technical program, under the prerequisite of maximum effective content providing Foam agent ADC A powder, ensure that the mixing uniformity of whipping agent powder and polyolefin resin pellet, realizes without dry linting phenomenon on this basis.Dispersion agent add the dispersion effect that also effectively improve powder and pellet, oxidation inhibitor can avoid polyolefin resin decomposition at high temperature, and tranquilizer plays and prevents the aging and whipping agent of polyolefin resin from decomposing.
The present invention also provides a kind of preparation method of dispersed whipping agent master batch, described dispersed whipping agent master batch uses twice dispersing method to be prepared from, the first step, first 50% of ADCA powder and dispersion agent small powder and oxidation inhibitor, tranquilizer are pre-mixed, separately carry out high speed shear blending dispersion by 50% of ADCA powder with polyolefin pellets, two of the first step kinds of pre-mixing dispersions are carried out high speed shear dispersion and obtain homodisperse whipping agent master batch by second step again.
Preferably, described method screw slenderness ratio be 52 screw extrusion press or high mixer in implement.
Tentatively pre-dispersed ensure that screw rod powder and pellet in feeding process carry out according to set ratio, and this is also ensure one of finely dispersed prerequisite.
Through preliminary pre-dispersed after, in screw rod, powder and pellet are also very crucial steps by carrying out further melting mixing.
The screw slenderness ratio L/D of screw extrusion press refers to the ratio of spiro rod length and diameter.L/D is the important factor of spiro rod plasticizing ability and effect, L/D greatly then material residence time in machine barrel long, be conducive to plasticizing, simultaneously pressure current, leakage current reduce, and improve plasticizing capacity, require that higher material is favourable to temperature distribution simultaneously.Longer screw slenderness ratio, extends the melting mixing time of pellet and powder thus has stopped dry linting phenomenon.
The technical program is owing to employing secondary blending dispersion method, and with the screw rod of larger length-to-diameter ratio shear achieve powder with pellet evenly mix, realize the homogeneity of abscess by controlling the dispersiveness of whipping agent in master batch, and there is stable quality.
Accompanying drawing explanation
Fig. 1 is that the present invention foams Ji master batch actual foaming situation picture.
