Description
The present invention relates to filler for plastic, specifically, the present invention relates to all purpose plastics packing parent grain and preparation method thereof.
As everyone knows, the weighting agent of always continuing to use in the plastic working comprises such as lime carbonate, magnesiumcarbonate, talcum powder, potter's clay, kaolin, mica, asbestos and carbon black etc., but above-mentioned weighting agent can not satisfy the requirement that different plastics are adjusted product performance and improved result of use etc.
So, the purpose of this invention is to provide a kind of all purpose plastics packing parent grain and preparation method thereof, described plastic filler parent granule can be used among most of thermoplasticss, to improve physics, chemistry and the mechanical property of plastics.
The objective of the invention is to realize in the following manner: all purpose plastics packing parent grain that a kind of thermoplastics is used is characterized in that:
(1) fineness is that the filler of 1-20 μ comprises:
A) zeolite 30-40%(weight);
B) white carbon black 30-40%(weight);
(2) molecular weight is that the polyethylene support of 1000-6000 comprises:
C) polyethylene wax 20-40%(weight), and
(3) conditioning agent comprises:
D) turps 5-7%(weight)
E) white oil or oneself penta tetrol methyl esters 2.5-3.5%(weight).
It is characterized in that:
(1) described filler is that the filler of fineness 2-10 μ comprises:
A) zeolite 30-35%(weight);
B) white carbon black 30-35%(weight);
(2) described carrier is that the polyethylene of molecular weight 2000-3000 comprises
C) polyethylene wax 20-30%(weight), and
(3) conditioning agent comprises:
D) turps 6%(weight) and
E) white oil 2%(weight).
It is characterized in that described conditioning agent comprises:
D) turps 5%(weight) and
E) penta tetrol methyl esters 2.5%(weight).
And the preparation method of all purpose plastics packing parent grain that a kind of thermoplastics is used is characterized in that:
(1) filler is comprised:
A) zeolite 30-40%(weight), preferably be 30-35%(weight),
B) white carbon black 30-40%(weight), preferably be 30-35%(weight), the drying machine is ground into the fineness of 1-20 μ by supper micron mill after 100-120 ℃ of oven dry, be preferably the fineness of 2-10 μ.
(2) carrier is comprised:
C) the molecular weight 1000-6000 polyethylene 20-40%(weight of molecular weight 2000-3000 preferably), preferably be 20-30%(weight), in molten-bath in 105 °-110 ℃ be melt into liquid after, be added in the kneading machine, and keep the polyethylene liquid dissolve standby at 105 °-110 ℃.
(3) with the polyethylene wax carrier in the above-mentioned prescription in molten-bath in 105 °-110 ℃ be melt into liquid after, be added in the kneading machine, and remain on 105 °-110 ℃, with above-mentioned drying, filler after the pulverizing is zeolite and b a)) after white carbon black mixes, be added in the above-mentioned kneading machine in batches and mediate with polyethylene liquid, when adding 1/3 filler a) zeolite and b) behind the mixture of white carbon black, conditioning agent d with 1/2) and e) be added in the kneading machine, in 105 °-110 ℃ kneaded 30 minutes after, add 1/3 above-mentioned filler a) zeolite and b again) behind the miscellany of white carbon black, the above-mentioned conditioning agent d that will be left again) and e) add wherein, kneaded 30 minutes in 105 °-110 ℃ then, the 1/3 above-mentioned filler miscellany that then will be left again is added in the kneading machine, kneaded 1.5-2.5 hour in 105 °-110 ℃, be added in the container then, material is cooled to room temperature, carry out precomminution again and become irregular particle, extrude (extrusion temperature is 60 °-90 ℃) through forcing machine then, be cut into the particulate product of required specification again, be all purpose plastics packing parent grain of the present invention.
Advantage of the present invention is tangible, because the crystalline phase of zeolite itself is characterized as the bulk cavernous body of cross skeleton, when it and most of thermoplastics are admixed, need not to use coupling agent can with the closely embedding mutually of plastics polymer, and help to absorb liberated heat when solidifying, therefore improved the forming ability of plastics.White carbon black is as filler, and its major function is to give plastics with low water-absorbent and excellent dielectric properties, improves processing characteristics simultaneously.As for the selected polyethylene wax of the present invention as carrier, its advantage is that it and most of thermoplastics have consistency, therefore, the plastic filler parent granule of method preparation of the present invention can directly and after the fusion of thermoplastics particle carry out injection moulding, extrusion molding or blowing, have easy to usely, with low cost, can regulate the quality of plastics and improve its chemistry, physical and mechanical property.
