Description
Fremgangsmåte til fremstilling av et sammensatt produkt på basis av glassfibre. Method for producing a composite product based on glass fibres.
Foreliggende oppfinnelse angår en fremgangsmåte til fremstilling av et sammensatt produkt på basis av glassfibre, der disse overtrekkes med et elastomert materiale, som kan vulkaniseres med<J >metalloksyder og som deretter herdes eller vulkaniseres, hvorved elastomeren bindes til glassfiberoverflåtene, ved at man for nevnte overtrekking anbringer på glassfiberoverflåtene eller innblander i elastomermaterialet et forankringsmiddel. The present invention relates to a method for producing a composite product based on glass fibers, where these are coated with an elastomeric material, which can be vulcanized with metal oxides and which is then hardened or vulcanized, whereby the elastomer is bonded to the glass fiber surfaces, by coating applies an anchoring agent to the glass fiber surfaces or mixes into the elastomer material.
En av hovedårsakene til innforing av glassfibre i elastomerer er at man onsker å bibringe de formede elastomerproduktene av en eller flere av glassfibrenes verdifulle egenskaper. De viktigste av disse er hoy strekkfasthet, kjemisk inerthet og god varmebestan-dighet. Det har vist seg at man ikke kan utnytte glassfibrenes styrke helt når fibrene- brukes i kombinasjon med elastomerer hvis man ikke oppnår en sterk og permanent forbindelse mellom elastomeren og glassfibrenes overflater. One of the main reasons for introducing glass fibers into elastomers is that one wishes to impart the shaped elastomer products with one or more of the glass fibers' valuable properties. The most important of these are high tensile strength, chemical inertness and good heat resistance. It has been shown that you cannot fully utilize the strength of the glass fibers when the fibers are used in combination with elastomers if you do not achieve a strong and permanent connection between the elastomer and the surfaces of the glass fibers.
Utviklingen av en sterk og permanent forbindelse mellom nevnte komponenter medforer forskjellige problemer som er spesielle for glassfibrene. I motsetning til naturfibre, såsom bomull, jute, silke og ull,' er glassfibrene fullstendig jevne og stavlignende, hvorfor det er vanskelig å oppnå fysisk forankring av elastomeren, og glassfibrenes hoye styrke kan ikke i noen storre grad oke ela-stomerproduktets styrke. I motsetning til naturfiber, såsom bomull, ull og silke, eller organiske, syntetiske fibre, såsom polyester ("Dacron"), polyamider :(nylon) og celluloseestere (rayon), angripes glassfibrene ikke av opplosningsmidler, eller oppmykes ved midlere temperaturer. Man kan således ikke benytte opplosningsmidler eller varme for å oppnå en forbindelse mellom glassfiberoverflåtene og The development of a strong and permanent connection between said components entails various problems which are particular to the glass fibres. In contrast to natural fibres, such as cotton, jute, silk and wool, the glass fibers are completely smooth and rod-like, which is why it is difficult to achieve physical anchoring of the elastomer, and the high strength of the glass fibers cannot to any great extent increase the strength of the elastomer product. In contrast to natural fibres, such as cotton, wool and silk, or organic, synthetic fibers, such as polyester ("Dacron"), polyamides :(nylon) and cellulose esters (rayon), the glass fibers are not attacked by solvents, or softened at moderate temperatures. One cannot therefore use solvents or heat to achieve a connection between the glass fiber surfaces and
elastomeren. the elastomer.
Ettersom det er således umulig å utnytte slike fysikalske krefter for å oppnå en sterk og permanent forbindelse mellom glassfiberoverflåtene og elastomeren, har forskningen blitt rettet mot utnyttelse av kjemiske krefter. Det har da vist seg at hydrofile grupper dominerer ved glassfiberoverflåtene, slik at disse attra-herer fuktighet sterkere enn organiske materialer, såsom elastomer. I nærvær av vann eller hoy luftfuktighet dannes det nesten umiddel-bart en tynn vannfilm på glassfibrene, som skiller disse fra elastomermaterialet, hvorved enhver opprinnelig forbindelse mellom glassfibrene og elastomeren blir meget svakere. As it is thus impossible to utilize such physical forces to achieve a strong and permanent connection between the glass fiber surfaces and the elastomer, research has been directed towards the utilization of chemical forces. It has then been shown that hydrophilic groups dominate at the glass fiber surfaces, so that these attract moisture more strongly than organic materials, such as elastomer. In the presence of water or high humidity, a thin film of water forms on the glass fibers almost immediately, which separates them from the elastomer material, whereby any original connection between the glass fibers and the elastomer becomes much weaker.
Foreliggende oppfinnelse er rettet mot utviklingen av glassfiber-elastomer-system, der glassfibrene kan utnyttes bedre enn armering for elastomeren ved tilvirkning av stopte eller laminerte elastomerprodukter, belagte fibre og vevnader og lignende. The present invention is aimed at the development of a glass fiber-elastomer system, where the glass fibers can be utilized better than reinforcement for the elastomer in the production of stopped or laminated elastomer products, coated fibers and weaves and the like.
En hensikt med foreliggende oppfinnelse er å oppnå en fremgangsmåte for fremstilling av glassfiber-elastomer-produkter med hoy styrke, der en sterk og permanent forbindelse kan utvikles mellom glassfibrene og elastomermaterialet, hvorved produktene er i stand til å bibeholde den onskede styrken og bøyeligheten, både i vann og i en atmosfære med hoy fuktighet. Produktene er lette å fremstille og de behandlede glassfibrene kan fremstilles som et mel-lomprodukt for etterfølgende bruk i kombinasjon med elastornermateri-aler til fremstilling av de forbedrede, glassfiberarmerte elastomerproduktene. En lignende hensikt er å oppnå en fremgangsmåte for fremstilling av produkter bestående av glassfibre og neopren, klorbutyl, naturgummi som inneholder harpikssyrer og lignende elastomer-materiale som kan vulkaniseres med metalloksyder, og blandinger av slike elastomerer med andre ord dermed kombinerbare elastomerer. One purpose of the present invention is to achieve a method for the production of glass fiber elastomer products with high strength, where a strong and permanent connection can be developed between the glass fibers and the elastomer material, whereby the products are able to maintain the desired strength and flexibility, both in water and in an atmosphere with high humidity. The products are easy to manufacture and the treated glass fibers can be produced as an intermediate product for subsequent use in combination with elastomeric materials for the manufacture of the improved glass fiber reinforced elastomeric products. A similar purpose is to achieve a method for the production of products consisting of glass fibers and neoprene, chlorobutyl, natural rubber containing resin acids and similar elastomer material that can be vulcanized with metal oxides, and mixtures of such elastomers, in other words elastomers that can be combined with it.
Dette oppnås ifølge oppfinnelsen ved en remgangsmåte som This is achieved according to the invention by a belt drive method which
er karakterisert ved at det som forankringsmiddel brukes dels(l) is characterized by the fact that it is used as an anchoring agent (l)
som i og for seg kjent et organosilån og/eller en kompleks kromforbindelse, inneholdende en med kromatomet koordinert karboksylatgruppe, i idet den i organosilanet til silisiumatomet bundne organiske gruppe, respektivt i kromkomplekset den med kromatomet koordinerte karboksylatgruppe, inneholder en alkenyl-, aryl- eller alkarylgruppe, dels (2) et aluminium-, sink- eller magnesiumhalogenid. as known in and of itself an organosilane and/or a complex chromium compound, containing a carboxylate group coordinated with the chromium atom, in that the organic group bound to the silicon atom in the organosilane, respectively in the chromium complex the carboxylate group coordinated with the chromium atom, contains an alkenyl, aryl or alkaryl group, partly (2) an aluminium, zinc or magnesium halide.
Med glassfibre menes her silkeglassfibre, som fremstilles ved rask tetrekning av smeltede glasstråler som kommer fra flere hull på undersiden av en glassmelteovn, stapelglassfibre, hvilke fremstilles ved rask strekning av smeltede glasstråler fra en glass-smelteovn ved hjelp av stråler av luft eller damp; strenger, garn og vevnader fremstilt av silkefibre eller stapelfibre, og glasspon i form av ualminnelig tynne og bøyelige glassfilmer. By glass fibers here is meant silk glass fibres, which are produced by rapid drawing of molten glass jets coming from several holes on the underside of a glass melting furnace, staple glass fibres, which are produced by rapid drawing of molten glass jets from a glass melting furnace using jets of air or steam; strings, yarns and webs made from silk fibers or staple fibers, and glass shavings in the form of unusually thin and flexible glass films.
Oppfinnelsen skal i det følgende beskrives i forbindelse med en kombinasjon av slike glassfibre og neopren eller klorbutyl som representative eksempler på elastomerer. Disse kjennetegnes av metallkloridgrupper, hvilke muliggjør vulkanisering av elastomeren i nærvær av metalloksyder. Oppfinnelsen kan også tillempes på andre elastomerer som inneholder slike metylklorider eller som vulkaniseres med metalloksyder. Oppfinnelsen angår også armering av elastomeren, der elastomerkomponenten består av neopren, klorbutyl eller andre elastomerer som kan vulkaniseres med metalloksyder, i kombinasjon med andre elastomerer som er kombinerbare med slik, såsom naturgummi, særskilt slik gummi som inneholder harpikssyrer. In the following, the invention will be described in connection with a combination of such glass fibers and neoprene or chlorobutyl as representative examples of elastomers. These are characterized by metal chloride groups, which enable vulcanization of the elastomer in the presence of metal oxides. The invention can also be applied to other elastomers that contain such methyl chlorides or that are vulcanized with metal oxides. The invention also relates to reinforcement of the elastomer, where the elastomer component consists of neoprene, chlorobutyl or other elastomers that can be vulcanized with metal oxides, in combination with other elastomers that can be combined with such, such as natural rubber, especially such rubber containing resin acids.
Ved hjelp av fremgangsmåten ifølge oppfinnelsen oppnås en forbedret sammenbinding mellom elastomermaterialet og glassfiber-overllatene på grunn av at ovennevnte metallhalogenid (aluminium-, sink- eller magnesiumhalogenid) brukes i kombinasjon med det angitte bindemiddel, dvs. silan eller kromkompleksforbindelsen. Metallhalo-. genidet kan innblandes i det uvulkaniserte elastomermateriale og/eller appliseres på glassfiberoverflåtene for å brukes i kombinasjon med nevnte bindemiddel, som appliseres på glassfiberoverflåtene. Under disse forhold har metallhalogenidet vist seg å kunne danne en bro mellom elastomerens umettede grupper eller metylkloridgrupper og Using the method according to the invention, an improved bond between the elastomer material and the glass fiber overlays is achieved due to the above-mentioned metal halide (aluminium, zinc or magnesium halide) being used in combination with the specified binder, i.e. silane or the chromium complex compound. Metal halo-. the genide can be mixed into the unvulcanized elastomer material and/or applied to the glass fiber surfaces to be used in combination with said binder, which is applied to the glass fiber surfaces. Under these conditions, the metal halide has been shown to be able to form a bridge between the elastomer's unsaturated groups or methyl chloride groups and
bindemidlets umettede eller aromatiske grupper under vulkanisering- the binder's unsaturated or aromatic groups during vulcanization
en av elastomeren, for derved å forbinde denne med bindemidlet, som i sin tur binder til glassfiberoverflåtene. Det kan nevnes at det i og for seg er kjent å bruke silaner eller kromkompleksforbindelser av ovennevnte type som beleggmiddel på glassfibre for å forbedre vedheftningen av harpiks på glassfibrenes flater. Det skal her vises til H. Hagen: "Glasfaserverstårkte Kunststoffe", 2. utgave, Berlin 1961, side_197-200. Man har imidlertid ikke tidligere ut-nyttet d" sse siln- eller kromkompleks bindemidler i kombinasjon med aluminium-, sink- eller magnesiumhalogenider i den hensikt å få one of the elastomer, thereby connecting this to the binder, which in turn binds to the fiberglass surfaces. It may be mentioned that it is known per se to use silanes or chromium complex compounds of the above type as a coating agent on glass fibers to improve the adhesion of resin on the surfaces of the glass fibers. Reference should be made here to H. Hagen: "Glasfaserverstårkte Kunststoffe", 2nd edition, Berlin 1961, page_197-200. However, these silicon or chromium complex binders have not previously been used in combination with aluminium, zinc or magnesium halides with the aim of obtaining
i stand ovennevnte samspill mellom bindemidlet og metallhalogenidet for dannelse av en bro til et elastromert materiale. capable of the above interaction between the binder and the metal halide to form a bridge to an elastomeric material.
Eksempel på hensiktsmessige bindemidler er vinyltroklor-silan, allyltrietoksisilan, fenyldiklorsilan, metakrylatkrom(III)-klorid. Examples of suitable binders are vinyltrochlorosilane, allyltriethoxysilane, phenyldichlorosilane, methacrylate chromium(III) chloride.
Bindemidlet og metallhalogenidet, kan anbringes sammen på glassfiberoverflåtene i passende mengder for å få et belegg med 0,3 - 3,0 t metallhalogenid og 0,1 - 3,0 % bindemiddel på glassfib-eroverf låtene. regnet i forhold til glassfibrenes vekt. Bindemid- The binder and the metal halide can be placed together on the glass fiber surfaces in suitable amounts to obtain a coating of 0.3 - 3.0 t metal halide and 0.1 - 3.0% binder on the glass fiber surfaces. calculated in relation to the weight of the glass fibres. Binder-
let kan også anbringes separat på glassfibrene, mens halogenidet kan anbringes som et dekningssjikt eller også innføres som en kom-ponent i elastomermaterialet. For å oppnå en ønsket konsentrasjon av bindemidlet og halogenid på glassfiberoverflåtene kan glassfibrene behandles med midler som inneho ....•ju.logenidet og bindemidlet oppløst i en konsentrasjon av 0,5 - 10 vektprosent. let can also be placed separately on the glass fibres, while the halide can be placed as a covering layer or also introduced as a component in the elastomer material. In order to achieve a desired concentration of the binder and halide on the glass fiber surfaces, the glass fibers can be treated with agents that contain the halogenide and the binder dissolved in a concentration of 0.5 - 10 percent by weight.
Oppfinnelsen skal i det følgende bli belyst nærmere ved eksempler. Prosenttallene er beregnet på vekten der ikke annet er angitt. In the following, the invention will be explained in more detail by means of examples. The percentages are calculated on the weight unless otherwise stated.
Eksempel 1. Example 1.
En vandig oppløsning stabilisert med ammoniumhydroksyd og inneholdende 0,5 % aluminiumsklorid og 1,0 % vinyltriklorsila-n anbringes på glassfiberoverflatene og tørkes for fiksering av det organiske silan og aluminiumkloriden på glassfiberoverflatene. An aqueous solution stabilized with ammonium hydroxide and containing 0.5% aluminum chloride and 1.0% vinyltrichlorosilane is applied to the glass fiber surfaces and dried to fix the organic silane and aluminum chloride to the glass fiber surfaces.
Glassfiber behandlet på denne måte blandes med uvulkaniserfe neoprengummi og formes ved 177 - 204°C og under trykk, for vulkanisering av elastomermaterialet. Fiberglass treated in this way is mixed with unvulcanized neoprene rubber and shaped at 177 - 204°C and under pressure, to vulcanize the elastomer material.
Eksempel 2. Example 2.
Glassfibrene belegges først med metakrylatkrom(III)-klorid i en vandig løsning med en konsentrasjon av ca. 1 fo. De belagte glassfibrene belegges deretter med en 1 % magnesium-klorid oppløsning. De behandlede glassfibrene blandes deretter i en mengde svarende til. 1 - 10 $ med uvulkanisert neoprengummi som inneholder magnesiumoksyd som vulkaniseringsmiddel i en mengde av ca. 2 %, hvoretter blanding-en vulkaniseres under varme og trykk. The glass fibers are first coated with methacrylate chromium(III) chloride in an aqueous solution with a concentration of approx. 1 fo. The coated glass fibers are then coated with a 1% magnesium chloride solution. The treated glass fibers are then mixed in an amount corresponding to 1 - 10 $ with unvulcanized neoprene rubber containing magnesium oxide as a vulcanizing agent in an amount of approx. 2%, after which the mixture is vulcanized under heat and pressure.
Eksempel 3. Example 3.
Glassfibre i form.av tekstiler, som først er blitt befridd for all tidligere påført appretur, behandles med en vandig løsning av difenyldihydroksisilan. Neopren i uvulkaniser tilstand blandes med 2 % aluminiumklorid såvel med andre fyllmidler og pigment, hvoretter den lamineres med flere sjikt glassfibertekstil til dannelse av laminat som kan formes under varme og trykk til et sammensatt produkt, hvilket glassfiberkomponenten er sterkt forankret i det vul-kaniserte elastomer-materiale. Glass fibers in the form of textiles, which have first been freed from all previously applied finishes, are treated with an aqueous solution of diphenyldihydroxysilane. Neoprene in an unvulcanized state is mixed with 2% aluminum chloride as well as with other fillers and pigment, after which it is laminated with several layers of glass fiber textile to form a laminate that can be formed under heat and pressure into a composite product, which glass fiber component is strongly anchored in the vulcanized elastomer -material.
Det må antas at silisiumoksydgruppene eller andre grupper på glassfibrenes overflate, og silisiumatomet i den organiske silisiumforbindelsen, eller polysiloksanets silisiumoksydbroer orienter-es i forhold til hverandre på glassfiberoverflatene for å oppnå en sterk og permanent forbindelse mellom de organiske silisiumforening-er og glassfibrene. Det viser seg, uberoende av årsaken, at den organiske silisiumforbindelsen bindes til glassfiberoverflatene for å modifisere deres egenskaper slik at overflatene beholder den organiske silisiumforbindelsen sterkt bundet selv ved høy fuktighet. It must be assumed that the silicon oxide groups or other groups on the surface of the glass fibers, and the silicon atom in the organic silicon compound, or the silicon oxide bridges of the polysiloxane are oriented in relation to each other on the glass fiber surfaces in order to achieve a strong and permanent connection between the organic silicon compounds and the glass fibers. It appears, regardless of the cause, that the organic silicon compound binds to the glass fiber surfaces to modify their properties so that the surfaces retain the organic silicon compound strongly bound even at high humidity.
Behahdl-ingsmidlé^kan påføres på glassfibrene ved bestryk-ning eller på annen kjent måte, f.eks. ved påsprøytning,. pårulling, dypping, belegging med pute, flytebelegging eller lignende. Man for-etrekker å anbringe bindemidlet direkte på de rene glassfibre. Behavioral agent can be applied to the glass fibers by coating or in another known way, e.g. by spraying. rolling on, dipping, coating with a pad, floating coating or the like. It is preferred to apply the binder directly to the clean glass fibers.
