Abstract
The present invention relates to a color master batch specially used for flexible polyvinyl chloride, and a manufacturing method thereof. The color masterbatch comprises the following components: polyvinyl chloride resin, pigments, plasticizers, extruding processing agents, heat stabilizers and dispersants. In the technology of the present invention, various powder raw materials except for the pigments are mixed; when the temperature of materials is higher than 80 DEG C, liquid raw materials are added; temperature is kept at 90 to 110 DEG C; when mixing and cooling are stopped, the pigments are added; the components are mixed to the needed temperature again; afterwards, the components are discharged in a cooling cylinder; the mixed material is put in an extruding machine for making pieces after cooling. Because both of main dispersion and homogenization are carried out in the forming process, mixing operation has low requirements, and technology control is simple; for inorganic pigments, the weight concentration of pigments can be more than 50%; the concentration of organic pigments can also be more than 40%, and the organic pigments can be used for manufacturing the color master batch with high concentration for the calendering production of polyvinyl chloride; both of the dispersivity and the homogenization degree of the color master batch are higher than that of the existing color cakes, and the color master batch has special advantages at the transparent PVC film coloration aspect.
Description
(1) technical field
The present invention relates to a kind of colour batch and manufacture method thereof that is exclusively used in soft PVC.
(2) background technology
The domestic and international at present manufacture method about the polyvinyl chloride colour batch can both find at many books and magazine, its major ingredient has polyvinyl chloride (PVC) RESINS, pigment powder, softening agent, processing aid and the thermo-stabilizer etc. of low polymerization degree, is processed into mill base, granular look mother or pie look mother usually.The pie colour batch adopts calendering technology production usually, and the pigment powder generally will add earlier behind the softening agent and grinds with two rollers, and then mixes with vector resin and auxiliary agent etc., banburying, opens refining, the moulding of cutting into slices at last.
(3) summary of the invention
The object of the present invention is to provide a kind of not only quality better, and the control of technology and the colour batch and the manufacture method thereof of operating fairly simple soft PVC.
In order to achieve the above object, the present invention utilizes polyethylene wax and softening agent that pigment is carried out surface treatment, reduces the surface energy of pigment, improves the affinity of pigment and polyvinyl chloride resin.In addition, use a large amount of dioctyl phthalate (DOP)s (DOP), the processing temperature of look cake is reduced significantly, reduce the possibility that degraded appears in look cake work in-process.Simultaneously, use N, N-ethylene distearyl acid amides (EBS) or stearic acid etc. to make as processing aid that the look cake is easier to be extruded.
The major ingredient of the special-purpose look cake of the said soft PVC of the present invention and content by weight are:
Polyvinyl chloride (PVC) RESINS is 100 parts,
Pigment is 5～200 parts,
Softening agent is 50～200 parts,
Extruding processing aid is 1～10 part,
Thermo-stabilizer is 1～10 part,
Dispersion agent is 10～30 parts.
The polymerization degree of said polyvinyl chloride (PVC) RESINS is optional to be used between 800～1250.
Wherein pigment is optional from organic pigment or mineral dye, and said pigment dyestuff can be selected from azo pigment, the blue or green pigment of phthalein, heterocycle pigment or pigment lake etc.; Said mineral dye can be selected from titanium dioxide, carbon black, iron oxide red or ultramarine powder etc.
Softening agent can be selected from phthalate, adipic acid ester class, citric acid ester type and epoxy soybean wet goods.
Extrude processing aid and can be selected from EBS or stearic acid etc.;
Thermo-stabilizer is optional from composition metal series, organotin, and antimony organic or rare earth material, wherein said composition metal series can be selected from Ba-Zn, Ba-Cd-Zn, Ca-Zn, Ba-Ca-Zn, K-Zn etc.
Dispersion agent is optional from polyethylene wax etc.
The technological process of production of the present invention is as follows:
1, the various powder raw materials except the pigment are dropped in the mixing machines mixes;
2, being higher than after 80 ℃ at temperature of charge, adding liquid starting material, keep temperature to be higher than 75 ℃, is 90～110 ℃ until mixing temperature, stops to mix;
3, add pigment after stopping to mix cooling 5～10min, and be mixed to temperature required 90～110 ℃ once more, be discharged into cooling then cylinder is cold and stir, cold stir to discharge below 60 ℃ standby;
4, cooled compound is dropped into forcing machine and make sheet, 110～150 ℃ of cross-head (mouthful mould) temperature, each section of machine barrel temperature is at 60～110 ℃.
Said forcing machine can adopt the cocurrent and parallel twin screw extruder.
The present invention adopts the cocurrent and parallel twin screw extruder that pigment is carried out final dispersion moulding.The cocurrent and parallel twin screw extruder can adopt the screw rod of length-to-diameter ratio greater than 1: 30 shallow slot triple thread, so that sufficiently long time and high-intensity shearing force to be provided, to reach the purpose of dispersion and homogenizing pigment.In order to make pigment be subjected to the strongest shearing under half plastifying state, each of extruder barrel section processing temperature should be controlled at below 110 ℃, degrades to avoid producing high temperature and PVC is produced under violent shear action.
The present invention carries out in moulding process owing to main dispersion and homogenizing, and is lower for the married operation requirement of leading portion, and then makes technology controlling and process oversimplify, also simple to operateization.For mineral dye, pigment weight concentration can reach more than 50%, and the concentration of pigment dyestuff also can reach more than 40%, can make high density look mother.
The present invention is used for PVC calendering and produces, and its dispersed and homogenizing degree all is higher than existing look cake, has more special advantage at the transparent PVC film aspect painted.
