Eräs tunnettu lasikuituvahvisteisen muovin valmistukseen tarkoitettu vahvistusaine käsittää toisiinsa yhdistetyt esilankakudos- ja lasikuitumattokerrokset. Käytettäessä pelkästään lasikuitumattoa vahvistusaineena vahvistetun tuotteen lasikuitupitoisuus ja siten veto- ja taivutus-lujuus jäävät alhaisiksi. Käytettäessä pelkästään esilanka-kudosta lasikuitupitoisuus ja siten veto- ja taivutuslujuus muodostuvat huomattavasti korkeammiksi. Useimmissa tapauksissa olisi sen tähden toivottavaa käyttää yksinomaan esi-lankakudosta vahvisteena. Kuitenkin on käynyt ilmi, että ainoastaan esilankakudoksesta muodostetussa laminaatissa on olemassa delaminoinnin vaara, mikä johtuu siitä, että 2 62247 viereisten esilankakudoskerrosten välisen rajakerroksen leikkauslujuus voi olla riittämätön. Delaminoinnin vaaraa voidaan vähentää sovittamalla lasikuitumattokerros viereisten esilankakudoskerrosten väliin ja sitomalla se esilanka-kudokseen hartsisideaineella. Tällainen vahvisteaineiden yhdistäminen helpottaa myös vahvistettujen tuotteiden valmistusta.One known reinforcing agent for the manufacture of glass fiber reinforced plastic comprises interconnected layers of pre-yarn fabric and glass fiber mat. When a fiberglass mat is used alone as the reinforcing material, the glass fiber content of the reinforced product and thus the tensile and bending strength remain low. When only the yarn is used, the glass fiber content and thus the tensile and flexural strength become considerably higher. In most cases, therefore, it would be desirable to use only the pre-yarn fabric as a reinforcement. However, it has been found that there is a risk of delamination only in the laminate formed from the pre-yarn fabric, due to the fact that the shear strength of the boundary layer between the adjacent pre-yarn fabric layers may be insufficient. The risk of delamination can be reduced by fitting a layer of glass fiber mat between adjacent layers of pre-yarn fabric and bonding it to the pre-yarn fabric with a resin binder. Such a combination of reinforcing agents also facilitates the manufacture of reinforced products.
Esilankakudoksesta ja lasikuitumatosta kokoonpantujen tuotteiden valmistuksessa käytetään tavallisesti jauheena olevaa hartsisideainetta. Tällöin voidaan lähtökohtana pitää esilankakudosta ja valmista mattoa ja jakaa jauhe tasaisesti toisen tuotteen ulkopuolelle, minkä jälkeen toinen sijoitetaan alapuoli jauhetta vastaan. Näin saatu tuote viedään uunin tai kuumennetun vyöhykkeen läpi, jossa jauhe sulaa ja kiinnittää kudoksen mattoon. Yhdistetty tuote voidaan myös saada aikaan levittämällä jauhe kerrokseksi esilankakudok-selle ja jakamalla hakattua lasikuitua jauheella sirotetulle kudokselle, minkä jälkeen näin saadulle tuotteelle suoritetaan tarpeellinen lämpökäsittely.A powdered resin binder is usually used in the manufacture of products assembled from yarns and fiberglass mats. In this case, the starting point can be the pre-yarn fabric and the finished carpet, and the powder is evenly distributed outside the other product, after which the other side is placed against the powder. The product thus obtained is passed through an oven or a heated zone where the powder melts and fixes the tissue to the mat. The combined product can also be obtained by applying the powder in a layer to the pre-yarn fabric and dividing the chopped glass fiber into the fabric sprinkled with the powder, after which the product thus obtained is subjected to the necessary heat treatment.
Esillä olevan keksinnön mukaisesti on osoittautunut mahdolliseksi valmistaa esilankakudoksesta ja lasikuitumatosta kokoonpantu aine, joka voidaan kyllästää huomattavasti nopeammin valmistettaessa lasikuituvahvisteista muovia olevia tuotteita kuin aikaisemmin tunnetut yhdistetyt aineet. Esillä olevan keksinnön mukaisesti saavutettava vaikutus selittyy todennäköisesti siten, että esillä olevan keksinnön mukaiseen yhdistettyyn aineeseen sisältyvä ja sen aineosat yhdistävä hartsisideaine esiintyy paikallisesti erittäin rajoitetuilla alueilla. Sen ansiosta hartsisideaine ei hidasta sen hartsin, useimmiten tyydyttämättömän polyesteri-hartsin, tunkeutumista, jota käytetään vahvistettujen muovituotteiden valmistuksessa. Aikaisemmin tunnetuissa yhdistetyissä aineissa hartsisideaine sitä vastoin esiintyy yhtenäisenä tai käytännöllisesti katsoen yhtenäisenä kerroksena esilankakudoksen ja lasikuitumaton välissä, minkä vuoksi tämä kerros on liuotettava vähintään olennaisessa 3 62247 määrin, ennen kuin saadaan aikaan yhdistetyn aineen täydellinen kyllästys vahvistettua muovia olevien tuotteiden valmistuksessa.According to the present invention, it has proved possible to produce a material assembled from a yarn yarn and a glass fiber mat, which can be impregnated considerably faster in the production of glass fiber reinforced plastic products than previously known combined materials. The effect to be achieved according to the present invention is probably explained by the fact that the resin binder contained in the combined substance according to the present invention and combining its components is present locally in very limited areas. As a result, the resin binder does not retard the penetration of the resin, most often unsaturated polyester resin, used in the manufacture of reinforced plastic products. In previously known composites, on the other hand, the resin binder is present as a uniform or substantially uniform layer between the pre-yarn fabric and the fiberglass mat, so that this layer must be dissolved at least substantially 3 62247 before complete impregnation of the composite in reinforced plastic products.
Tarkemmin sanottuna esillä olevan keksinnön kohteena on toisiinsa yhdistetyt esilankakudos- ja lasikuitumattokerrokset käsittävä lasikuitutuote, joka tunnetaan olennaisesti siitä, että esilankakudos ja lasikuitumatto on yhdistetty toisiinsa niiden väliin, sinänsä tunnetulla tavalla sovitetuilla erillisillä tekstiilikuitulangoilla, jotka ainakin pinnaltaan on varustettu huoneen lämpötilassa kiinteällä hartsisideai-neella. Menetelmä tämän tuotteen valmistamiseksi tunnetaan olennaisesti siitä, että liuottimeen liuotettu hartsiside-aine levitetään tekstiilikuitulangoille, edullisesti lasi-kuitulangoille, jotka sitten sovitetaan esilankakudoksen ja lasikuitumaton väliin, minkä jälkeen liuotin poistetaan esi-lankakudoksesta, lasikuitumatosta ja tekstiilikuitulangois-ta kokoonpannusta aineesta, jolloin nämä aineosat yhdistyvät toisiinsa hartsisideaineella.More specifically, the present invention relates to a fiberglass product comprising interconnected layers of prewoven fabric and fiberglass mats, characterized in that the prefabricated fabric and the fiberglass mat are interconnected by separate textile fiber yarns arranged in a manner known per se. The process for making this product is essentially characterized in that the resin binder dissolved in the solvent is applied to textile fiber yarns, preferably glass fiber yarns, which are then interposed between the yarn and the glass fiber, after which the solvent is removed from the yarn, the glass fiber and the textile fiber assembly. to each other with a resin binder.
Esilankakudos ja lasikuitumatto voivat olla tavanomaista ja kaupallisesti saatavissa olevaa lajia.The pre-yarn fabric and the fiberglass mat may be a conventional and commercially available species.
Tekstiilikuitulangat voivat olla orgaanista tai epäorgaanista ainetta, esim. polyeteeniglykolitereftalaattia, polyamidia, polyakryylinitriiliä, selluloosaa, lasia tai asbestia. Erityisesti lasikuitulangat ja varsinkin jatkuvat lasikuitu-langat sopivat käytettäviksi. Valmistuksen kannalta on edullista sovittaa langat välein esilankakudoksen ja lasikuitu-maton pituussuuntaan, mutta periaatteessa on mahdollista sovittaa ne muihin suuntiin, esim. esilankakudoksen ja lasikuitumaton poikkisuuntaan. Olennaista on se, että ne on sovitettu sellaisella tavalla, että lankojen peittämä esilankakudoksen tai lasikuitumaton pinnan osa on olennaisesti pienempi kuin se osa, joka ei ole niiden peittämä.The textile fiber yarns may be an organic or inorganic material, e.g. polyethylene glycol terephthalate, polyamide, polyacrylonitrile, cellulose, glass or asbestos. Fiberglass yarns in particular, and in particular continuous fiberglass yarns, are suitable for use. From a manufacturing point of view, it is advantageous to fit the yarns at intervals in the longitudinal direction of the pre-yarn fabric and the fiberglass mat, but in principle it is possible to fit them in other directions, e.g. in the transverse direction of the pre-yarn fabric and the fiberglass mat. Essentially, they are arranged in such a way that the part of the pre-yarn fabric or non-glass fiber surface covered by the yarns is substantially smaller than the part which is not covered by them.
Kuten yllä olevasta käy ilmi, hartsisideaineen tulee olla kiinteää huoneen lämpötilassa. Sen kemiallinen koostumus ei 4 62247 ole ratkaisevan tärkeä. Hartsisideaine voi mm. olla poly-esterihartsia, epoksihartsia, polyuretaanihartsia, fenoli-hartsia, piihartsia jne. Hartsisideaine on edullisesti myös liuottimeen liukenevaa, jotta sitä voidaan yksinkertaisella tavalla levittää lasikuitulangoille, ennenkuin nämä viedään esilankakudoksen ja lasikuitumaton väliin. Mitä tahansa sellaista liuotinta voidaan käyttää, joka pystyy liuottamaan hartsisideaineen. On edullista, jos liuotin on helposti haihtuvaa. Periaatteessa on kuitenkin mahdollista levittää hartsisideaine liuotinta käyttämättä viemällä langat hartsi-sideainesulatteen läpi. Jos langat ovat sulavaa polymeeriä, esim. polyeteeniglykolitereftalaattia, voidaan itse lankoja tai itse lankojen ulko-osia käyttää hartsisideaineena. Ainakin lankojen ulko-osat on tällöin väliaikaisesti saatettava sulaan muotoon, kun ne on levitetty esilankakudoksen ja lasikuitumaton väliin, edullisesti viemällä yhdistetty aine uunin läpi.As indicated above, the resin binder should be solid at room temperature. Its chemical composition is not critical. The resin binder may e.g. be a polyester resin, an epoxy resin, a polyurethane resin, a phenolic resin, a silicon resin, etc. The resin binder is preferably also solvent-soluble so that it can be simply applied to the glass fiber yarns before they are passed between the pre-yarn fabric and the glass fiber mat. Any solvent capable of dissolving the resin binder can be used. It is preferred if the solvent is volatile. In principle, however, it is possible to apply the resin binder without using a solvent by passing the yarns through a resin-binder melt. If the yarns are a fusible polymer, e.g. polyethylene glycol terephthalate, the yarns themselves or the outer parts of the yarns themselves can be used as a resin binder. At least the outer parts of the yarns must then be temporarily rendered molten after being applied between the pre-yarn fabric and the glass fiber mat, preferably by passing the combined material through an oven.
Keksinnön mukaisessa lasikuitutuotteen edullisessa valmistusmenetelmässä liuottimeen liuotettu hartsisideaine levitetään tekstiilikuitulangoille, erityisesti lasikuitulangoille, minkä jälkeen nämä hartsisideaineen ja liuottimen kera sovitetaan esilankakudoksen ja lasikuitumaton väliin, minkä jälkeen liuotin poistetaan esilankakudoksesta, lasi-kuitumatosta ja tekstiilikuitulangoista kokoonpannusta aineesta.In a preferred method of manufacturing the glass fiber product of the invention, the solvent-resin-bonded resin binder is applied to textile fiber yarns, particularly glass fiber yarns, after which
Keksintöä selitetään lähemnin suoritusesimerkin avulla oheiseen piirustukseen viitaten, jonka kuvio esittää laitetta keksinnön mukaisen lasikuitutuotteen valmistamiseksi.The invention will be explained in more detail by means of an exemplary embodiment with reference to the accompanying drawing, the figure of which shows an apparatus for manufacturing a fiberglass product according to the invention.
Kuviossa 1 merkitsee esilankakudosta 2 sisältävää rullaa ja 3 lasikuitumattoa 4 sisältävää rullaa. Esimerkkitapauksessa 2 esilankakudoksen pintapaino on 600 g/m ja lasikuitumaton 2 pintapaino 300 g/m . Esilankakudoksessa on loimessa 1,4 lankaa/cm, jonka paksuus on 2400 tex tai 2 x 1200 tex, ja kuteessa 1,3 lankaa/cm, jonka paksuus on 2400 tex. Lasikui-tumatto koostuu hakattua lasikuitua olevista kimpuista, 5 62247 jolloin 40 painoprosentilla on 25 mm:n pituus ja 60 painoprosentilla 50 mm:n pituus. Kuidut on yhdistetty toisiinsa kiinteällä polyesterihartsilla, jonka pitoisuus matossa nousee 5 %:iin maton kokonaispainosta. Kiinteällä polyesterihartsilla voi olla sama koostumus kuin hartsisideaineella, joka levitetään lasikuitulangoille ja jota seuraavassa selitetään esimerkein.In Fig. 1 denotes a roll containing 2 yarns and 3 rolls containing a fiberglass mat 4. In the exemplary case 2, the surface weight of the yarn yarn is 600 g / m 2 and the glass fiber nonwoven 2 has a basis weight of 300 g / m 2. The pre-yarn fabric has 1.4 yarns / cm with a thickness of 2400 tex or 2 x 1200 tex in the warp and 1.3 yarns / cm with a thickness of 2400 tex in the weft. The fiberglass mat consists of bundles of chopped fiberglass, 5 62247 with 40% by weight having a length of 25 mm and 60% by weight having a length of 50 mm. The fibers are bonded together with a solid polyester resin, the concentration of which in the mat rises to 5% of the total weight of the mat. The solid polyester resin may have the same composition as the resin binder applied to the glass fiber yarns and will be explained by way of example below.
Esilankakudoksen 2 ja lasikuitukudoksen 4 väliin johdetaan useita lasikuitulankoja 5 yhdensuuntaisesti useilta puolilta 6a, 6b, 6n. Ennen kuin langat joutuvat kosketukseen esilankakudoksen ja lasikuitumaton kanssa, ne kulkevat liuotti-meen liuotettua hartsisideainetta sisältävän kylvyn 7 läpi, jolloin langat kyllästetään kylvyn sisällöllä. Liuotin haihtuu lankojen (jotka on tässä merkitty 8:11a) sijaitessa esilankakudoksen 2 ja lasikuitumaton 4 välissä. Hartsisideaine, joka on kiinteää, saa tällöin aikaan sidoksen esilankakudoksen ja lasikuitumaton välille. Jos liuotin on helposti haihtuvaa ja rullauslaitteen 9 pyörimisnopeus ja etäisyys rullasta 3 sopivasti sovitetut, liuotin haihtuu huoneen lämpötilassa, ennenkuin yhdistetty aine on ehditty kelata rul-lauslaitteelle, jota käyttää ei esitetty käyttölaite. Esitetyssä tapauksessa pinnoitetaan 25 lankaa kudoksen ja maton leveysmetriä kohti, ts. 4 cm:n jaolla, ja langat ovat kertaamatonta lasilankaa, jonka paksuus on 73 tex. Kylvyn 7 hartsisideaine on kiinteää polyesteriä, esim. kaupalliselta nimeltään Atlac 3305 (Kemiintressen, Tukholma), ja liuotin esim. etyyliasetaattia. Esimerkkinä esitetyn hartsisideai-neen sijasta voidaan muun muassa käyttää hartsisideainetta, joka on valmistettu 415 osasta isoftaalihappoa, 224 osasta buteeniglykolia, 229 osasta trimetyylipropaania ja 146 osasta adipiinihappoa, jotka on saatettu reagoimaan happo-lukuun 10. Liuottimen haihduttua yhdistetystä aineesta se on valmista käytettäväksi.Between the pre-yarn fabric 2 and the fiberglass fabric 4, a plurality of glass fiber yarns 5 are passed in parallel from several sides 6a, 6b, 6n. Before the yarns come into contact with the pre-yarn fabric and the glass fiber mat, they pass through a bath 7 containing a resin binder dissolved in a solvent, whereby the yarns are impregnated with the contents of the bath. The solvent evaporates as the yarns (labeled 8: 11a) are located between the pre-yarn fabric 2 and the fiberglass mat 4. The resin binder, which is solid, then provides a bond between the pre-yarn fabric and the fiberglass mat. If the solvent is easily volatile and the rotational speed and distance of the winding device 9 and the distance from the roll 3 are suitably adjusted, the solvent evaporates at room temperature before the combined substance has been wound on a winding device used by a drive device not shown. In the case shown, 25 yarns are coated per meter of fabric and carpet width, i.e., in 4 cm increments, and the yarns are a non-repeating glass yarn having a thickness of 73 tex. The resin binder for bath 7 is a solid polyester, e.g. under the trade name Atlac 3305 (Kemiintressen, Stockholm), and the solvent is e.g. ethyl acetate. Instead of the exemplary resin binder, a resin binder prepared from, inter alia, 415 parts of isophthalic acid, 224 parts of butene glycol, 229 parts of trimethylpropane and 146 parts of adipic acid, which have been reacted with an acid number 10, can be used.
Esillä olevan keksinnön mukaista lasikuitutuotetta voidaan käyttää lasikuituvahvisteisten tuotteiden valmistukseen tavanomaisin menetelmin. Se sopii esim. erinomaisesti lasi-The fiberglass product of the present invention can be used for the production of fiberglass-reinforced products by conventional methods.
