Description

DK 164027 B
Opfindelsen angår en fremgangsmåde til fremstilling af forstærkede termoplastiske laminater ud fra termoplas-tiske baner, der er forskellig eller uforligelige.
5 I ansøgerens europæiske patentansøgning nr. 85300032.1 (publikation nr. 0 148 761) er der beskrevet en fremgangsmåde til fremstilling af en fiberforstærket bane af plastmateriale. Baner af denne type, hvori der er indlejret forskelliae arter af termoplastisk materiale, 10 som ikke let binder sammen er vanskelige at laminere, hvis de er blevet konsolideret ved sammenpresning. Det har imidlertid nu vist sig, at det er muligt at fremstille et sådant laminat, hvis de som udgangsmateriale tjenende baner er ukonsoliderede, som beskrevet i europæisk pa-15 tentansøgning nr. 85300031.3 (publikation nr.
0 148 760) eller er blevet expanderet fra en konsolideret tilstand som beskrevet i ansøgerens europæiske pa-tentansøqninq nr. 85300024.7 (publikation nr. 0 148 763).
Fremgangsmåden ifølge opfindelsen, der er af den i ind-20 ledningen til krav 1 angivne art, er ejendommelig ved det i den kendetegnende del af krav 1 angivne. Indholdet af porøsitet af banen kan være inhærent i den ukonsoliderede tilstand af den som udgangsmateriale tjenende bane, eller det kan genereres ved at expande-25 re en konsolideret bane.
Fortrinsvis er en væsentlig andel af fibrene mellem 7 og 50 mm lange og 13 μπι eller derunder i diameter. Hensigtsmæssigt foreligger fibrene også i form af enkelte, separate glasfibre. Sådanne fibre tilvejebringes ofte 30 i sammenbundet tilstand i afskårne bundter af strenge, og disse må nedbrydes til enkelte fibre før banen dannes .
2
DK 164027 B
Når det kræves, at fibrene skal meddele laminatet strukturel styrke, bør de separate glasfibre ikke være kortere end ca. 7 mm eller af en diameter, der er over 13 um, fordi sådanne fibre, som er længere, ikke på passende 5 måde forstærker plastmatrixen, og fibre, der har større diameter, ikke på effektiv måde forstærker matrixen.
Som -et alternativ kan man anvende enkelte fibre af andre materialer, der har en forstærkende effektivitet, der mindst er lige så høj som glasfibre.
10 Ued et højt elasticitetsmodul forstås et elasticitets modul, der er væsentligt højere end banens elasticitetsmodul. Fibre, der falder i denne kategori, omfatter glasfibre, carbonfibre og keramiske fibre og sådanne fibre som aramid-fibre, der sælges under varemær-15 kerne Kevlar og Nomex, og de vil generelt omfatte en hver fiber, der har et modul, der er højere end 10.000 Mega Pascal.
Som anført i det foregående kan banerne først konsolideres og derpå expanderes ved varmepåvirkning før 20 laminering.
Ved en alternativ metode kan de ikke konsoliderede baner tildannes og tørres sammen før laminering.
De termoplastiske materialer kan f. eks. være af poly-ethylen, polypropylen, polystyren, acrylonitrilstyren- 25 butadien, polyethylenterephthalat, polybutylenterephtha- lat eller polyvinylchlorid, både blødgjonte og ikke blød-gjorte, eller legeringer eller blandinger af disse materialer med hinanden eller med andre polymere materialer. Andre passende termoplaster omfatter poly-30 phenylenether eller polycarbonater eller polyester- carbonater eller termoplastiske polyestere eller 3
DK 164027 B
polyetherimider eller acrylonitril-butylacrylat-sty-ren-polymere eller amorpft nylon eller polyarylen-ether-keton eller legeringer eller blandinger af disse materialer med hinanden eller med andre polymere ma-5 terialer.
Opfindelsen kan udøves på mange måder, og nogle eksemplificerende udførels es former skal nu beskrives under henvisning til tegningen, hvorpå fig. 1 viser en fremgangsmåde til sammenføjning af dis-10 se baner til et laminat, ifølge kendt teknik.
fig. 2 viser en fremgangsmåde til fremstilling af et laminat ifølge opfindelsen, fig. 3 viser en alternativ fremgangsmåde, 15 fig. 4 viser en anden alternativ fremgangsmåde, og fig. 5 viser en fremgangsmåde til fremstilling af en genstand, hvor man gør brug af laminatet fremstillet ved fremgangsmåden ifølge opfindelsen.
I de følgende eksempler fremstillede man de porøse ba- 2 20 ner A og B, så de opnåede en total vægt af 2.000 g/m , hver af dem i henhold til den fremgangsmåde, der er angivet i europæisk patentansøgning nr. 85300032.1 (publikation nr. 0 148 761), hvorved hver bane indeholder 25 vægt-% glasfibre (11 pm i diameter og 13 mm lange), 25 men dispergeret i et andet termoplastisk materiale.
Bane A blev som vist på tegningen fremstillet med polypropylen, kvalitet GY545M, fremstillet af I.C.I. Limited, og bane B blev fremstillet med ΧΕΝ0Υ, en termoplastisk legering af polycarbonat og polybutylentere-30 phthalat fremstillet af'G.E. Plastics Irre.

DK 164027 B
Laminater blev fremstillet på fire forskellige måder, som vist på tegningen. Adhæsionen mellem lagene blev bedømt subjektivt ved at skære en strimmel 15 mm bred og 200 mm lang, og ved at vride dens ender i de modsat-5 te retninger, indtil der enten forekom aflaminering eller et tværgående brud.
EKSEMPEL 1 (blindprøve)
Som vist på fig. 1 blev ikke konsoliderede tørre baner A og B, fremstillet som beskrevet i europæisk paid tentansøgning nr. 85300031.3 (publikation nr. 0 148 760), individuelt varmt presset ved henholdsvis 190 og 260°C og afkølet for at fremstille koldkonsoliderede baner 1 og 2. De koldkonsoliderede baner A og B blev derpå varmt presset sammen i en presse 3 under et 15 tryk af 14 kg/cm , hvorved temperaturerne af presse- pladerne i kontakt med banerne er henholdsvis 170 og 250°C. Det resulterende laminat 4 blev afkølet, og når det blev undersøgt, viste det sig at udvise meget ringe adhæsion mellem komponentbanerne 20 EKSEMPEL 2
Som vist på fig. 2 blev banerne A og B, der tidligere var konsolideret, opvarmet og expanderet på den måde, der er beskrevet i europæisk patentansøgning nr.
85300034.7 (publikation nr. 0 148 763), således at de 25 blev permeable, som angivet ved henvisningstallene 5 og 6. De expanderede baner blev placeret sammen i en 2 presse 3, hvor de blev udsat for et tryk af 14 kg/cm ved en temperatur af 90°C. Det resulterende laminat blev afkølet, og adhæsionen mellem komponentlagene 30 viste sig at være bedre end ved den metode, der er 5
DK 164027 B
beskrevet i forbindelse med fig. 1.
EKSEMPEL 3
Som vist på fig. 3 blev ukonsoliderede baner A og B
af den art, der blev anvendt ved begyndelsen af eksempel 1, 5 anordnet samm-en i pressen 3, hvor de blev udsat for et 2 tryk af 14 kg/cm , hvorved pressepladerne havde en temperatur af henholdsvis 170 og 250°C. Man lod det resulterende laminat afkøle, og det viste sig, at der forelå en udmærket adhæsion mellem komponentlagene.
10 EKSEMPEL 4
Som vist på fig. 4 blev ukonsoliderede tørre baner A og B af den type, der er anvendt i eks. 1, tildannet og tørret sammen før de blev anordnet i den varme presse, hi/or de blev udsat for den samme behandling som i eksem-25 pel 3. Der opnåedes en udmærket adhæsion mellem komponent lågene.
EKSEMPEL 5
Fig. 5 viser en fremgangsmåde til fremstilling af en genstand af et laminat 8, der er fremstillet i hen-20 hold til metoden fra eksempel 3. Laminatet 8 er anordnet i et på passende måde opvarmet formeværktøj 9- i en presse 10, hvis to plader er opvarmet til 90°C, og udsat 2 for et tryk af 140 kg/cm med henblik på fremstilling af en formet genstand 11.
25 I afhængighed af de anvendte materialer kan man variere efterbehandlingen af laminatet eller formelegemet. Hvis således banen A har et relativt lavt glasfiberindhold, f. eks. 25?ί, vil den lavere overflade 12 af den fremstillede genstand blive tildannet med en ret glat finish. På 6
DK 164027 B
den anden side vil et højt glasfiberindhold, f. eks. på 60?ό, resultere i en porøs overflade, der tilveje-bringer en nøgle for et overfladedannende lag, der påføres derefter.
5 Opfindelsen tilvejebringer derfor en teknik til frem- stil-ling af en formet genstand ud fra et laminat, som f. eks. kan omfatte en varmeresistent bane på en side og en let formbar bane på den anden side, fremstillet ud fra et billigere termoplastmateriale. Det 10 vil forstås, at opfindelsen også udstrækker sig til dannelsen af laminater, der har mere end to lag. Man kan f. eks. tilvejebringe en af tre lag bestående bane, der har et kernelag af fiberforstærket polypropylen og overfladedannende lag af fiberforstærket ny-15 Ion.
I det følgende eksempel blev en skive med en diameter af 22 cm af et laminat af glasmåtte/polypropy-len med en vægt af 4000 g/m og et glasfiberindhold af 40/0, solgt under varemærket AZDEL, opvarmet til 20 205°C i 7,5 minutter i en ovn og lamineret i en skål- 2 formet form under et tryk af 140 kg/em til det specificerede laminat.
EKSEMPEL 6
Den anden komponent af laminatet omfattede et porøst 25 ukonsolideret banelignende materiale, der havde en vægt af 3000 g/m og var fremstillet som beskrevet i europæisk patentansøgning nr. 85300031.3 (publikation nr 0 148 760) ud fra 30¾ glasfibre, der var 12 mm lange og 11 jum i diameter, og 70¾ Nylon 6 pulver solgt 30 under varemærket MARANYL 236R af ICI Ltd. Når det re sulterende laminat bliver afkølet, udviste det god 7
DK 164027 B
adhæsion mellem banerne.
