Description
Fremgangsmåte til fremstilling av mykningsmiddel- og esningsmiddel-holdig pulverformet polyvinylklorid resp. vinylkloridholdige sampolymerisater. Process for the production of plasticizer- and emulsifier-containing powdered polyvinyl chloride resp. vinyl chloride-containing copolymers.
Det er kjent å fremstille skumlegemer It is known to produce foam bodies
av blandinger av polyvinylklorid resp. vinylkloridholdige sampolymerisater med et of mixtures of polyvinyl chloride or vinyl chloride-containing copolymers with a
mykningsmiddel og esningsmiddel. Frem-gangsmåten består i at man river mykningsmiddel, esningsmiddel og polyvinylklorid til en pasta og eser opp denne i åpne plasticizer and thickener. The procedure consists of tearing plasticizer, emulsifier and polyvinyl chloride into a paste and edging this into open
eller lukkede former. Ulempene ved denne or closed forms. The disadvantages of this
fremgangsmåte er at pastaen er bundet procedure is that the paste is bound
til en bestemt lagringstid og lagringstem-peratur og ikke egner seg til fremstilling to a specific storage time and storage temperature and is not suitable for manufacturing
av skumstoffer ved hjelp av et utsprøyt-ningsapparat (extruder). Det er også kjent of foam substances using an extrusion device (extruder). It is also known
å fremstille termoplastiske polymerisater to produce thermoplastic polymers
med flytende mykningsmidler ved den så-kalte «dry blend»-metode under bibehold with liquid softeners by the so-called "dry blend" method while maintaining
av pulverformen, idet der anvendes en of the powder form, using a
blander med en rotor hvis turtall kan re-guleres slik at den vesentlige del av den mixes with a rotor whose speed can be regulated so that the essential part of it
energi som er nødvendig for oppvarming, energy required for heating,
oppstår ved friksjon, og at massen ved occurs by friction, and that the mass at
hvirvling holdes svevende, samtidig som vortex is kept floating, at the same time as
mykningsmiddelet tilsettes kontinuerlig the plasticizer is added continuously
ved en temperatur mellom 70 og 120° C. at a temperature between 70 and 120°C.
Det blev funnet at man kan fremstille It was found that one can produce
mykningsmiddel- og esningsmiddel-holdig containing emollients and emulsifiers
polyvinylklorid resp. vinylkloridholdige polyvinyl chloride or containing vinyl chloride
sampolymerisater på en slik måte åt de copolymers in such a way they ate
foreligger i pulverform, hvis man fordeler is available in powder form, if distributed
esningsmiddelet fint i det flytende mykningsmiddel og i en egnet hurtigløpende the emulsifier fine in the liquid softener and in a suitable fast-running
blander, f. eks. en væskeblander (Fluid-Mischer) fra Henschel Werke G.m.b.H., mixers, e.g. a fluid mixer (Fluid-Mischer) from Henschel Werke G.m.b.H.,
Kassel, Tyskland av den art som f. eks. Kassel, Germany of the kind that e.g.
anvendes for «dry blend»-fremstilling, used for "dry blend" production,
blander den resulterende blanding med mixing the resulting mixture with
polyvinylkloridet, slik at mykningsmiddelet opptas av polyvinylklorider, uten at esningsmiddelet spaltes av den varme som opptrer under blandeprosessen. Egnede es-ningsmidler er f. eks. i og for seg kjente forbindelser som dinitroso-pentamethylen-tetramin og det azodicarbonamid som markedsføres under betegnelsen «Porofor K». Da opptagelsen av mykningsmiddel i polyvinylklorid osv. er begrenset hvis man skal få upåklagelige pulverformede blandinger, kan man øke innholdet av mykningsmiddel ved etterpå å tilblande mykningsmiddel i fast form. Som mykningsmiddel i fast form egner seg bl. a. urin-stoffharpikser med et mykningspunkt i nærheten av 75° C, f. eks. PLASTOPAL H the polyvinyl chloride, so that the plasticizer is taken up by polyvinyl chlorides, without the emulsifier being split by the heat that occurs during the mixing process. Suitable food additives are e.g. per se known compounds such as dinitroso-pentamethylene-tetramine and the azodicarbonamide marketed under the name "Porofor K". As the absorption of plasticizer in polyvinyl chloride etc. is limited if impeccable powdery mixtures are to be obtained, the content of plasticizer can be increased by subsequently adding plasticizer in solid form. As a plasticizer in solid form, e.g. a. urea resins with a softening point near 75° C, e.g. PLASTOPAL H
(handelsprodukt fra Badische Anilin- & (trade product from Badische Anilin- &
Sodafabrik) og URESIN B (handelsprodukt fra Farbwerke Hoechst), samt di-ethyldifenylurinstoff med et smeltepunkt Sodafabrik) and URESIN B (commercial product from Farbwerke Hoechst), as well as di-ethyldiphenylurea with a melting point
på 72° C. Den store økonomiske fordel lig-ger i at der nu av disse utgangsstoffer ved at 72° C. The great economic advantage lies in the fact that now of these starting materials at
passende utførelse av sprøyteapparatet kan fremstilles profilprodukter av alle øn-skede former. suitable design of the spraying apparatus can produce profile products of all desired shapes.
Eksempel 1. Example 1.
12 vektdeler «Profor K» med et spalt-ningspunkt på 190—230° C samt en stabili-sator og farvestoff blir tilsatt 40 vektdeler av et flytende mykningsmiddel og meget fint fordelt. I en blander med hurtigroterende blandeaggregat blir denne blanding tilsatt 60 vektdeler polyvinylklorid og blandet med dette inntil mykningsmiddelet er opptatt av polyvinylkloridet. Den slutt-temperatur blandingen når på grunn av friksjonsvarmen, er ca. 120° C. Etter avkjøling foreligger blandingen i pulverform. Ved etterfølgende tilføyelse av 20 vektdeler av et fast mykningsmiddel lar det seg gjøre å å øke blandingens innhold av mykningsmiddel. 12 parts by weight of "Profor K" with a splitting point of 190-230° C as well as a stabilizer and dye are added to 40 parts by weight of a liquid plasticizer and very finely distributed. In a mixer with a fast-rotating mixing unit, 60 parts by weight of polyvinyl chloride are added to this mixture and mixed with this until the plasticizer is absorbed by the polyvinyl chloride. The final temperature the mixture reaches due to the heat of friction is approx. 120° C. After cooling, the mixture is in powder form. By subsequently adding 20 parts by weight of a solid plasticizer, it is possible to increase the plasticizer content of the mixture.
Eksempel 2. 10 vektdeler «Porofor K» med et spalt-ningspunkt på 190—230° C samt en stabi-lisator og farvestoff blir tilsatt 30 vektdeler av et flytende mykningsmiddel og fordelt meget fint. Denne blanding blir i en blander med hurtigroterende blandeaggregat tilsatt og blandet med 30 vektdeler polyvinylklorid inntil mykningsmiddelet er opptatt av dette. Den slutt-temperatur blandingen når på grunn av friksjonsvarmen, er ca. 120° C. Etter avkjø-ling foreligger blandingen i pulverform. Ved etterpå å tilføye 30 vektdeler fast mykningsmiddel kan man øke blandingens innhold av mykningsmiddel. Example 2. 10 parts by weight of "Porofor K" with a splitting point of 190-230° C as well as a stabilizer and dye are added to 30 parts by weight of a liquid plasticizer and distributed very finely. This mixture is added and mixed with 30 parts by weight of polyvinyl chloride in a mixer with a fast-rotating mixing unit until the plasticizer is absorbed by it. The final temperature the mixture reaches due to the heat of friction is approx. 120° C. After cooling, the mixture is in powder form. By subsequently adding 30 parts by weight of solid plasticizer, the mixture's plasticizer content can be increased.
