Description
Oppfinnelsen vedrører armeringsmaterialer i form av fibre og/eller fyllstoffer til bruk ved fremstilling av armert herdeplast. The invention relates to reinforcement materials in the form of fibers and/or fillers for use in the production of reinforced thermosetting plastics.
Umettede kunstharpikser og monomerer som styren og Unsaturated synthetic resins and monomers such as styrene and
akrylater herder vanligvis ved at det tilsettes en acrylates usually harden by adding a
a) akselerator og a) accelerator and
b) katalysator. b) catalyst.
Plaststoffet som dannes ved oppherding kalles The plastic material that is formed during curing is called
gjerne herdeplast. Por å oppnå beare mekanisk styrke på en herdeplast armeres denne med glassfiber, karbonfiber o.l. preferably hard plastic. In order to achieve sufficient mechanical strength on a thermosetting plastic, this is reinforced with glass fibre, carbon fiber etc.
Selve herdingen av-den umettede kunstharpiks foregår <;>The actual curing of the unsaturated synthetic resin takes place <;>
som oftest etter følgende to mekanismer: most often by the following two mechanisms:
1) Redox system. 1) Redox system.
Katalysator danner radikaler ved at den utsettes for et reduserende stoff. Det vanligste reduksjonsmiddel er Co -ioner. Catalyst forms radicals when it is exposed to a reducing substance. The most common reducing agent is Co ions.
Mekanismen er sannsynligvis følgende:. The mechanism is probably the following:
(Tobolsky and Mesrobian, Organic Peroxides, Wiley (interscience) New York, 1954). (Tobolsky and Mesrobian, Organic Peroxides, Wiley (interscience) New York, 1954).
2) Horner-Schlenk mekanismen. 2) The Horner-Schlenk mechanism.
En rekke aminer vil initiere dannelsen av frie A number of amines will initiate the formation of free
radikaler når det kommer i kontakt med peroksyder. radicals when it comes into contact with peroxides.
Horner-Schlenk har forklart dette på følgende måte: Horner-Schlenk has explained this as follows:
(Horner and Schlenk, Angew. Chemie 61. 411, 1949). (Horner and Schlenk, Angew. Chemie 61. 411, 1949).
Umettede kunstharpikser benyttes oftest sammen med monomerer som styren og/eller akrylater for å oppnå ønskede egenskaper, både i bearbeidingsfasen og i det endelige produkt. Unsaturated synthetic resins are most often used together with monomers such as styrene and/or acrylates to achieve desired properties, both in the processing phase and in the final product.
Akselerator er vanligvis tilsatt denne blandingen Accelerator is usually added to this mixture
av kunstharpiks og monomer, idet stabiliteten på et slikt system er relativt lang, oftest flere måneder. Stabiliteten kan dessuten reguleres ved tilsats av en inhibitor, f.eks. hydroquinon. of synthetic resin and monomer, as the stability of such a system is relatively long, usually several months. The stability can also be regulated by adding an inhibitor, e.g. hydroquinone.
Umiddelbart før bruk tilsettes en katalysator som metyletylketonperoksyd, cyclohexanonperoksyd, acetylaceton-peroksyd, benzoylperoksyd o.l. Immediately before use, a catalyst such as methyl ethyl ketone peroxide, cyclohexanone peroxide, acetylacetone peroxide, benzoyl peroxide etc. is added.
Så snart peroksydet er tilsatt, starter herdingen. Kunstharpiksblandingen geler, vanligvis etter 20 til 60 min. Vanligvis avformes produktet etter 4-6 timer, optimal As soon as the peroxide is added, the curing starts. The synthetic resin mixture gels, usually after 20 to 60 min. Usually the product is de-shaped after 4-6 hours, optimally
utherding kan ta minst ett døgn. curing can take at least a day.
Ved fremstilling av armert herdeplast benyttes som armeringsmaterialer glassfiber, karbonfiber, polyamidfiber, In the production of reinforced thermosetting plastic, glass fiber, carbon fiber, polyamide fiber are used as reinforcing materials,
og lignende. and such.
Disse fibrene fordeles og arbeides godt inn i den flytende umettede kunstharpiks som er tilsatt herdesystem. These fibers are distributed and worked well into the liquid unsaturated synthetic resin to which the curing system has been added.
Under denne prosessen har man forholdsvis kort tid til disposisjon, da herdereaksjonen, som nevnt, starter strakt katalysator og akselerator er kommet sammen i den umettede kunstharpiks. During this process, you have a relatively short time at your disposal, as the hardening reaction, as mentioned, starts when the catalyst and accelerator have come together in the unsaturated synthetic resin.
Hittil er akselerator og katalysator tilsatt den umettede kunstharpiks (event. -blandingene) før denne bringes i kontakt med fibrene. Until now, accelerator and catalyst have been added to the unsaturated synthetic resin (or mixtures) before this is brought into contact with the fibres.
Oppfinnelsen vedrører altså armeringsmaterialer i The invention therefore relates to reinforcement materials i
form av fibre til bruk ved fremstilling av armert herdeplast, idet materialene er karakterisert ved at det i fiberappreturen, fibermattebindemidlet eller i fibrene er inkorporert akseleratorsystem eller katalysator. form of fibers for use in the production of reinforced thermosetting plastics, the materials being characterized by the fact that an accelerator system or catalyst is incorporated in the fiber finish, the fiber mat binder or in the fibers.
Fibrene kan være glassfibre, karbonfibre, metall-tråder, polyamidfibre eller annet egnet fiberformet materiale, enten som ubearbeidede fibre eller bearbeidet til matte, roving, vevet roving, hugget fiber, eller i annen bearbeidet form. The fibers can be glass fibres, carbon fibres, metal threads, polyamide fibers or other suitable fibre-shaped material, either as unprocessed fibers or processed into mats, roving, woven roving, chopped fibre, or in other processed form.
Akseleråtorsystemet kan være Co-, Fe-, Mn-, V- eller Pb-forbindelser, amin eller annen akseleratortype alene, eller i kombinasjon. The accelerator rotor system can be Co, Fe, Mn, V or Pb compounds, amine or other accelerator type alone, or in combination.
Katalysatoren kan være peroksyd eller annen katalysa-tortype; eller blandinger av sådanne. The catalyst can be peroxide or another type of catalyst; or mixtures thereof.
Oppfinnelsen vedrører videre en fremgangsmåte til fremstilling av ovennevnte armeringsmaterialer, idet frem-gangsmåten er karakterisert ved at akseleråtorsystemet eller katalysatoren oppløses, emulgeres, dispergeres eller bindes kjemisk til en i og for seg kjent appretur eller et fibermattebindemiddel før påføring på fibrene. The invention further relates to a method for producing the above-mentioned reinforcement materials, the method being characterized by the accelerator system or catalyst being dissolved, emulsified, dispersed or chemically bound to a per se known finish or a fiber mat binder before application to the fibres.
Videre kan, ifølge oppfinnelsen, akseleråtorsystemet eller katalysatoren i form av oppløsning, emulsjon, dispersjon eller i fast form, påføres fiberproduktene direkte. Furthermore, according to the invention, the accelerator system or the catalyst in the form of solution, emulsion, dispersion or in solid form can be applied directly to the fiber products.
Ifølge oppfinnelsen blir altså akseleratorsystera, eventuelt katalysator, inkorporert i armeringsfiberen. According to the invention, the accelerator system, possibly a catalyst, is incorporated into the reinforcing fiber.
Herdeprosessen starter da først i det øyeblikk kunstharpiks og arraeringsmateriale kommer i kontakt. På denne måte unngås at kunstharpiks (blanding) geler i kar og påføringsapparatur. Dette medfører store besparelser i fprm av mindre svinn av råstoff, redusert redskapsforbruk, lettere renhold med mindre bruk av organisk oppløsningsmiddel, og derved vesentlig forbedret arbeidsmiljø. Brannfaren reduseres vesentlig på grunn av følgende forhold: Vesentlig redusert håndtering.av peroksyd (katalysator) ved at minst en dags behov av umettet kunstharpiks og katalysator kan blandes i én operasjon. Dessuten unngår man at rester av kunstharpiks-blanding tilsatt både akselerator og katalysator starter en ukontrollert sterk eksoterm herdereaksjon som ofte har vært årsak til branner. The curing process then only starts the moment the synthetic resin and coating material come into contact. In this way, it is avoided that the synthetic resin (mixture) gels in vessels and application equipment. This results in major savings in terms of less wastage of raw materials, reduced tool consumption, easier cleaning with less use of organic solvents, and thereby a significantly improved working environment. The risk of fire is significantly reduced due to the following factors: Significantly reduced handling of peroxide (catalyst) as at least one day's need for unsaturated synthetic resin and catalyst can be mixed in one operation. In addition, it is avoided that residues of synthetic resin mixture added with both accelerator and catalyst start an uncontrolled strong exothermic curing reaction which has often been the cause of fires.
Som følge av at herdeprosessen først starter når armeringsmaterialet med inkorporert akselerator kommer i kontakt med den umettede kunstharpiks med innblandet katalysator, har operatøren bedre tid til disposisjon, og derfor større mulighet til å korcnsa freift til et teknisk bedre produkt. As a result of the hardening process only starting when the reinforcement material with an incorporated accelerator comes into contact with the unsaturated synthetic resin with a mixed catalyst, the operator has more time at his disposal, and therefore a greater opportunity to refine the product into a technically better product.
