Abstract
The present invention relates to a processing manufacturing method of thermoplastic rubber (TPR) and a product thereof, particularly to a manufacturing method of calendered shaped films and plates, and a product thereof. In the method of the present invention, TPR (SBS, SEBS and the mixtures of the SBS and the SEBS) materials are applied to adhesive plaster machines which are not applied to the TPR materials in days gone by for being calendered, processed and shaped into films and plates, or are further attached to base fabric for being made into leather with base fabric for being applied to the processing of leather bags, shoes, general merchandises, etc. for being used as multiple replacing materials for replacing PVC materials, etc. The present invention uses adhesive plaster machines which are not applied to the TPR materials in days gone by to the calendering process and the producing process of films and plates, selects proper TPR grades (MI (180 DEG C) is larger than 1) and properly controls temperature to be 120 DEG C to 170 DEG C for causing the melting viscosity of the TPR materials to be 20000 poises to 80000 poises for causing the TPR to be capable of being processed and calendered by adhesive plaster machines and to be made into needed films, plates and rubber stuck with base fabric.
Description
Thermoplastic elastomer TPR (Thermo Plastic Rubber) material generally all is used for penetrating and extrusion processing, has not used adhesive tape machine calendering processing.
Ejaculation is processed high molecular design focal point with extrusion and is flowability; As penetrate processing, batch is melted state in heat clamp-on with pressure in the ejaculation mould, and extrusion processing is then flowed out through the T-pattern and filmed on briquetting roller in the casting mode; And adhesive tape machine calendering processing focus on felicity condition, prescription control melt strength material can be extended according to need in processing procedure, make the surface of material inadhesion in former, obtain the film shape goods that need.
The ejection formation processing of TPR material, be after TPR resin, colorant, lubricant, stabilizing agent etc. are mixed, insert in the ejaculator, according to the difference of batch, temperature can be warming up to 170 ℃～250 ℃, make batch become the good flow state, the melting charge that again screw rod is advanced in the recipient chamber is injected among the jetting mold, in addition moulding, cooling and finished product, its moulding product are individual shape, as the accessories of using as sole replacement rubber.
Extrusion molding processing is extensive not as ejection formation aspect TPR material range of application.It is with TPR micelle and colorant, stabilizing agent, after processing aids such as lubricant mix, put into extruder, firing equipment on the extruder recipient, divide three～five sections and will expect that temperature rise is to moulding temperature required (170 ℃ according to need～250 ℃), there is one in the recipient according to metering, mixing, the demand of feeding is different and screw rod that the structure design is different, after being entered, compound can reach the purpose of fusion gel according to the order of sequence, go out behind the screw rod after filtration, harmonious material device (Static Mixer), the T pattern is with the even good material of flowability, be evenly distributed extrusion die, and coat electroplating surface light or be carved with on the briquetting roller of lines in addition cooling forming, obtain finished product.
Thermoplastic elastomer contains SBS, SEBS, and its melt viscosity is low than PVC; PVC is fit to adhesive tape machine processing, and its melt viscosity is 20000～80000 pools; And the TPR material is if select the grade of MI (180 ℃)＞1, and then its temperature slightly high (170 ℃～200 ℃) if melt viscosity is reduced to below 20000 pools, can be adhered to the moulding wheel face, peels off difficulty, can't process; And the TPR material if MI (180 ℃)＜1 o'clock, then it still is difficult for gel in 150 ℃～170 ℃ and flows (its viscosity too high＞80000 pools), and temperature more than 170 ℃, the easy sticking wheel of flavescence deterioration then, difficult forming.
SBS (styrene butadiene styrene block copolymer (SBS)), SEBS (styrene-ethylene butylene-styrene block copolymer) and blending compound thereof are because of melt viscosity, undercapacity, with present conventional techniques processing difficulties when adhesive tape machine calendered film, the sheet, so that never utilized this mode to process.
In view of this, through research with keen determination, the beginning has been finished method for making of the present invention.Select TPR and batch for use with suitable MI, with suitable operating condition, finally develop and utilize adhesive tape machine calendering film forming, the method of sheet, also be about to TPR micelle (MI (180 ℃)＞1), colorant (0～40PHR), zinc stearate (0.2～2.0PHR), lubricants such as PE-WAX (0.05～1.0PHR), antioxidant (0.3～2.5PHR), ultra-violet absorber (mixed with high-speed mixer (as 1 among Fig. 1) by 0.3～2.5PHR) grade, compound is dropped into ten thousand horsepowers of machines (2 among Fig. 1), in 110～150 ℃ of temperature ranges roll compacting 2-6 minute, make material evenly mix to be merged into and melt blob of viscose shape material, drop into mixing rolling in the turbine (3 among Fig. 1) again in 110 ℃～170 ℃ abundant stirrings, promote to mix and the gel degree, after filtering extruder (4 among Fig. 1) elimination impurity, drop into adhesive tape machine (5 among Fig. 1) again, adhesive tape machine wheel surface temperature is 120 ℃～170 ℃, operation viscosity is 20000～80000 pools, before, on, in, the lower whorl rotating ratio is 1: (1.25～1.35): (1.28～1.38): (1.31～1.41), roll the thickness that becomes to need, again through embossed wheel (as 6 among Fig. 1) in 10 ℃～60 ℃ embossing of temperature, cooling wheel (as 7 among Fig. 1) is in 10 ℃～60 ℃ temperature ranges, with TPR film cooling forming, batch with coiling machine (as 8 among Fig. 1) more at last.
This method for making as need not ten thousand horsepowers the equipment of the then available extrusion kneader of machine or the close function of tool, and as need not mixingly roll turbine, then available planet extruder or the good extruder of other mixing functions, its calendering formation machine is then constant; These processing procedure main points are the temperature of suitably control calendering formation machine and the appropriateness collocation of prescription.
When processing the TPR batch in above-mentioned calendering mode, it is rolled the film, the sheet that the base fabric of can fitting in addition, base fabrics such as bondedfibre fabric, flat fabric, knitted cloth are through sending frame (6 among Fig. 2 A), when rolling, adhesive tape machine upward fits with the above-mentioned diaphragm that rolls in embossed wheel (5 among Fig. 2 A), make TPR rubber, and described base fabric in advance through the coating of stickers such as the lower molecular weight dissolved matter of TPR or PU paste with strengthen and TPR film, sheet between adhesion strength; Paste the semi-finished product of base fabric and handle back (as 10 among Fig. 2 B) with the PU finishing agent, extrude the finished product of various lines again through embossing machine, preheating wheel (as 14 among Fig. 2 C), heater (as 15 among Fig. 2 C), embossed wheel (16 among Fig. 2 C), through cooling wheel (as 17 among Fig. 2 C) typing, batch (18 among Fig. 2 C) at last again.
The present invention is applicable to adhesive tape machine calendering processing for making TPR, is the TPR (SBS or SEBS) that adopts melt index MI=1～50 (180 ℃).
The present invention uses colorant for making finished product have various needed color and lusters, and PE look grain or look grain can use separately or fusion is used, and its consumption can optionally adopt 0～40PHR.
The used lubricant of the present invention is selected from zinc stearate, Tissuemat E, and it mainly act as in the adhesive tape machine calender line, increases TPR in the release that adds man-hour, reduces in the TPR forming process and the glutinous viscosity between equipment (as roller).Its consumption is looked release to be needed to adopt zinc stearate 0.2～2.0PHR, Tissuemat E 0.05～1.0PHR.
For prolonging the time that TPR film of the present invention, rubber use out of doors and preventing the uviolize inferior solution that wears out, can adopt antioxidant and ultra-violet absorber; Its consumption is looked weather resisteant to be needed can adopt antioxidant 0.3～2.5PHR, ultra-violet absorber 0.3～2.5PHR.
