Lämpligen är dessutom alla hydrokylgrup- perna i alkoholerna omsatta under bildning av ester (COO)-bindnin- gar, dvs det kommer inte att finnas några fria hydroxylgrupper i estern.Preferred organic esters as the above component D are the esters wherein the aliphatic carboxylic acids are hydrocarbon-based acids, containing 1-3 carboxyl groups, preferably 1 or 2, and consists of 4-10 carbon atoms, and wherein the alcohols are aliphatic. With in other words, the R groups in the alcohols are alkyl or alkylene groups depending on the R group used in the particular case. When carb- the oxyl acids contain 2 or more carboxyl groups, are additionally 79o135o-4 preferably the carboxyl groups are all reacted to form esters. ter (C00) bonds, ie there will be no free ones carboxyl groups in the ester. In addition, all hydrocyl groups are suitably the alcohols reacted to form ester (COO) linkages. ie there will be no free hydroxyl groups in estern.
Som specifika föreningar, vilka faller inom ramen för dessa defi- nitioner, kan nämnas följande (sifferuppgiften inom parentes efter varje förening anger det antal grader Celcius, som 1 vikt-% av den ingående föreningen (räknat på polyetentereftalatet) i den armerings- eller fyllmedelshaltiga etentereftalatplasten sänker Tpk): butyl- karbitoladipat (2,9), trietylenglykolkaprat-kaprylat (2,7).As specific compounds, which fall within the scope of these nitions, the following can be mentioned (the figure in parentheses after each compound indicates the number of degrees Celsius as 1% by weight of it the compound (based on the polyethylene terephthalate) in the reinforcement or filler-containing ethylene terephthalate plastic lowers Tpk): butyl- carbitol adipate (2.9), triethylene glycol caprate caprylate (2.7).
Komponenterna (C) och (D) i kompositionerna enligt uppfinningen bi- drar till att ge formade alster med hög ytglans vid formningstem- peraturer under 110°C genom att öka polyetentereftalatets kristal- ' liseringshastighet. Komponent (C) antages i första hand bidra till *ökningen av kristalliseringshastigheten, medan komponent (D) förmo- das i första hand förbättra polyetentereftalatets rörlighet i dess underkylda_tillstând genom att reducera den underkylda blandningens viskositet. Båda är nödvändiga för att erhålla den höga glans, som erhålles hos produkter som formas av kompositionen enligt uppfin- ningen.Components (C) and (D) in the compositions of the invention are produces molded articles with a high surface gloss at molding temperatures. temperatures below 110 ° C by increasing the crystallinity of the polyethylene terephthalate 'lization rate. Component (C) is primarily assumed to contribute to * the increase in the crystallization rate, while component (D) primarily improve the mobility of polyethylene terephthalate in its supercooled_ state by reducing the supercooled mixture viscosity. Both are necessary to obtain the high gloss, which obtained from products formed from the composition according to the invention ningen.
Mängden komponent (C), som föreligger i kompositionerna enligt upp- finningen, uppgår till en mängd, som kommer att ge ett AHH/AHc-för- hållande för kompositionen under 0,25. För att fastställa AHH/AHc- förhållandet formas polyetentereftalatet vid 70°C till 1,6 mm tjocka stänger. Stängerna uppvärmes och vid mellan 95OC och 120°C registre- ras en exoterm (betecknad AHH) med hjälp av en differentialavsök- ningskalorimetercell (DSC-cell), som kopplats till en differential- termisk analysanordning av typen “Du Pont 900 Differential Thermal Analysis (DTA) device". Stângen uppvärmes till 290°C (som ligger över dess smältpunkt) och det smälta provet kyles med 10°C/minut.The amount of component (C) present in the compositions according to the amount, which amounts to an AHH / AHc ratio keeping the composition below 0.25. To determine AHH / AHc- ratio, the polyethylene terephthalate is formed at 70 ° C to 1.6 mm thick closes. The rods are heated and at 95 ° C to 120 ° C registered exotherm (designated AHH) by means of a differential scan calorimeter cell (DSC cell), which is connected to a differential thermal analysis device of the type “Du Pont 900 Differential Thermal Analysis (DTA) device ". The rod is heated to 290 ° C (lying above its melting point) and the molten sample is cooled at 10 ° C / minute.
En annan exoterm vid mellan ca 200 och 220°C (betecknad'AHc) är den exoterm, som registreras vid nedfrysning av provet. Det har visat sig, att AHH/AHC-förhållandet är en lämplig metod att mäta graden av kristallisation.Another exotherm at between about 200 and 220 ° C (denoted'AHc) is that exotherm, which is recorded when the sample is frozen. It has shown that the AHH / AHC ratio is an appropriate method of measuring the degree of crystallization.
Tpk för kompositionen enligt uppfinningen är den temperatur, vid vilken värme utvecklas snabbast under det i föregående stycke redo- 7901350- 4 visade uppvärmningsförloppet. Såsom framhâllits tidigare är den mängd av komponent (D), som ingår i kompositionen enligt uppfin- ningen, en mängd som sänker Tpk för kompositionen med minst 4°C relativt Tpk för en identisk komposition, som inte innehåller nå- gon komponent (D).Tpk for the composition according to the invention is the temperature, at which heat is developed most rapidly during the period described in the previous paragraph. 7901350- 4 showed the heating process. As previously pointed out, it is amount of component (D) contained in the composition according to the invention an amount which lowers the Tpk of the composition by at least 4 ° C relative to Tpk for an identical composition, which does not contain any gon component (D).
De övre gränserna för mängderna av komponenterna C och D är i och för sig inte kritiska. De fysikaliska egenskaperna kan emellertid påverkas ogynnsamt samtidigt som mängderna ökar. Den övre gräns, som användes för endera av de båda komponenterna, ligger därför vid 12 vikt-%, räknat på vikten polyetentereftalat, medan den undre gränsen är 0,5 resp. 1 vikt-%. För de föredragna, som komponent (C) utnyttjade salterna av eten/metakrylsyra-sampolymer uppgår den öv- re gränsen vad gäller mängden till ca 12 vikt-%, räknat på vikten polyetentereftalat, medan den undre gränsen ligger omkring 0,5%, men lämpligen användes en mängd inom omrâdet 2-7%.The upper limits of the amounts of components C and D are in and individually not critical. However, the physical properties can adversely affected while volumes increase. The upper limit, which is used for either of the two components, is therefore adjacent 12% by weight, by weight of polyethylene terephthalate, while the lower the limit is 0.5 resp. 1% by weight. For those preferred, as component (C) the salts of ethylene / methacrylic acid copolymer used amount to the re limit in terms of quantity to about 12% by weight, calculated on the weight polyethylene terephthalate, while the lower limit is around 0.5%, but suitably an amount in the range of 2-7% is used.
Förutom de ovan redovisade komponenterna kan kompositionerna enligt uppfinningen innehålla sådana tillsatser, som allmänt utnyttjas tillsammans med esterplaster, t.ex. färgämnen, släppmedel, antioxi- danter, stabilisatorer mot inverkan av ultraviolett ljus, flamskydds- medel och liknande ämnen. Tillsatser, som förbättrar sådana fysika- liska egenskaper som t.ex. draghâllfasthet och töjning, kan också utnyttjas och bland sådana tillsatser kan nämnas epoxiföreningar (t.ex. en epoxiförening, som bildas av bisfenol-A och epiklorhyd- rin), som föreligger i mängder av 0,1-1,5 vikt-%, räknat på kompo- sitionens vikt.In addition to the components described above, the compositions according to the invention contain such additives which are widely used together with ester plastics, e.g. dyes, release agents, antioxidants ultraviolet light stabilizers, flame retardants agents and similar substances. Additives which improve such physics physical properties such as tensile strength and elongation, can also are used and among such additives may be mentioned epoxy compounds (eg an epoxy compound formed by bisphenol-A and epichlorohydride rin), which is present in amounts of 0.1-1.5% by weight, calculated on the the weight of the situation.
Kompositionerna enligt uppfinningen framställes genom att man blan- dar samman komponenterna på något lämpligt sätt. Varken temperatur eller tryck är kritiska faktorer. Polyetentereftalatet kan t.ex. blandas torrt i någon lämplig blandare eller trumma tillsammans med komponenterna B, C och D, varefter blandningen strängsprutas i smält form. Det ur sprutmaskinen utgående materialet kan skäras upp i bitar aflxblandas med armeringsmedel, varefter denna blandning strängsprutas i smält form. Lämpligare är dock att blanda samtliga komponenter i torrt tillstånd i någon lämplig blandare eller trum- ma och att sedan strängspruta blandningen i smält form.The compositions of the invention are prepared by mixing assembles the components in any suitable way. Neither temperature or pressure are critical factors. The polyethylene terephthalate can e.g. mix dry in a suitable mixer or drum together with components B, C and D, after which the mixture is extruded into molten form. The material leaving the sprayer can be cut up in pieces aflxmixed with reinforcing agent, after which this mixture extruded in molten form. However, it is more appropriate to mix them all components in the dry state in any suitable mixer or drum ma and then extruded the mixture into molten form.
I följande exempel beskrives det bästa sättet att tillämpa uppfin- ningen. AHH/AHC-förhållandet och Tpk bestämdes på det sätt, som 7901350-4 beskrivits ovan. Det formade provets glans mättes med en glansmä- tare av typen “Gardner Multi Angle Gloss (Model GG-9095)“, som var» inställd vid en utvald i exemplet angiven vinkel.The following examples describe the best mode for applying the invention. ningen. The AHH / AHC ratio and Tpk were determined as follows 7901350-4 described above. The gloss of the shaped sample was measured with a gloss meter. Gardner Multi Angle Gloss (Model GG-9095), which was » set at a selected angle specified in the example.
Exempel ïorrt polyetentereftalat (PET) med en inre viskositet av ca 0,6 blanaaaès manuellt med 25% (räknat på totalvikt) “ocF 277 B" glas- fiber, 5,7% (räknat på polyetentereftaletets vikt) eten/metakryl- syra-sampolymer (viktförhållande 85/15), som hade neutraliserats till 60% med natrium (som här är komponent C) och med 5,7% (räknat på polyetentereftalatets vikt) trietylenglykolkaprat-kaprylat (som här är komponent D), 0,6% (räknat på totalvikt) av produkten av bis- fenol A och epiklorhydrin samt 0,3% (räknat på totalvikten) av en fenolisk antioxidant. Komponent C gav ett AHH/AHC-förhållande av 0,16, och komponent D gav en Tpk som var 15,40 lägre än Tpk för en blandning av de andra beståndsdelarna.Example Polyethylene terephthalate (PET) with an intrinsic viscosity of about 0.6 blanaaaès manually by 25% (calculated on total weight) "ocF 277 B" glass- fiber, 5.7% (by weight of polyethylene terephthalate) ethylene / methacrylic acid copolymer (weight ratio 85/15), which had been neutralized to 60% with sodium (which here is component C) and with 5.7% (calculated on the weight of the polyethylene terephthalate) triethylene glycol caprate-caprylate (as here, component D), 0.6% (by total weight) of the product of bis- phenol A and epichlorohydrin and 0.3% (by weight) of a phenolic antioxidant. Component C gave an AHH / AHC ratio of 0.16, and component D gave a Tpk which was 15.40 lower than the Tpk for one mixture of the other ingredients.
Den erhållna blandningen strängsprutades sedan genom en tvåstegs 5 cm enkelskruvsprutmaskin vid en smälttemperatur av 285°C och vid ett vakuum av 71 cm. Den strängsprutade strängen skars i bitar, och de erhållna plastgrynen torkades vid 110°C i en vakuumugn under ca 16 timmar. Plastgrynen formades sedan till formstycken, som ha- de formen av ett dricksglas utan fot och som var 9,2 cm höga, hade en diameter av 7,5 cm längst upp och 5,5 cm vid botten och en vägg- tjocklek av 0,19 cm. Smälttemperaturen i formningsmaskinen uppgick till 295°C, medan fornæns yttemperatur var 85°C vid en arbetsför- loppstid av 10/20.The resulting mixture was then extruded through a two-stage 5 cm single screw sprayer at a melting temperature of 285 ° C and at a vacuum of 71 cm. The extruded strand was cut into pieces, and the resulting plastic groats were dried at 110 ° C in a vacuum oven below about 16 hours. The plastic groats were then formed into moldings, which they had the shape of a drinking glass without a foot and which was 9.2 cm high a diameter of 7.5 cm at the top and 5.5 cm at the bottom and a wall thickness of 0.19 cm. The melting temperature in the forming machine was to 295 ° C, while the surface temperature of the furnace was 85 ° C at a working run time of 10/20.
'Glansen mättes vid en vinkel av 600 med ovannämnda glansmätare fle- ra gånger på varje prov. Glansen mättes runt periferin på det dricks- glasformade formstycket vid en tredjedel av den totala höjden uppi- från räknat. Den högsta avläsningen var 64 och den lägsta 50.The gloss was measured at an angle of 600 with the above-mentioned gloss meter ra times on each sample. The gloss was measured around the periphery of the drinking glass-shaped molding at one third of the total height up to from counted. The highest reading was 64 and the lowest 50.
I ett jämförelseförsök utnyttjades exakt samma beståndsdelar med undantag för att inget trietylenglykolkapratkaprvlat användes. Det högsta glansvärdet som erhölls uppgick till 20 och det-lägsta var 15. Dessutom måste arbetsförloppet vid formningen ökas till 10/30 sekunder, som anger injektionstiden i förhållande till kvarhållnings- tiden, för att få ut delarna ur formen. Av detta försök framgår sålunda, att komponent D är nödvändig för att erhålla väsentligt högre glansvärden.In a comparison experiment, exactly the same components were used except that no triethylene glycol caprate caprylate was used. The the highest gloss value obtained was 20 and the lowest was 15. In addition, the workflow during shaping must be increased to 10/30 seconds, which indicates the injection time in relation to the retention time, to get the parts out of the mold. This experiment shows thus, that component D is necessary to obtain substantially higher gloss values.
