THERMOHARDENDE PERSCOMPOUNDS OP BASIS VAN PHENOLISCHE RESOLHARSTHERMO-CURING PRESS COMPOUNDS BASED ON PHENOLIC RESOL RESIN
De uitvinding betreft thermohardende harssamenstellingen, in het bijzonder perscompounds, op basis van phenolische resolhars, vulstof en basische condensatie katalysatoren, en eventueel indifckingsmiddel(en), glasvezel en verder gebruikelijke additieven.The invention relates to thermosetting resin compositions, in particular press compounds, on the basis of phenolic resole resin, filler and basic condensation catalysts, and optionally a thickening agent (s), glass fiber and further usual additives.
5 Dergelijke harssamenstellingen zijn bijvoorbeeld bekend uit het amerikaans octrooischrift no. 4075155. Deze bekende harssamenstellingen geven echter bij het thermisch uitharden aanleiding tot moeilijkheden in verband met het in de resolhars aanwezige water.Such resin compositions are known, for example, from US patent no. 4075155. However, these known resin compositions give rise to difficulties in thermally curing in connection with the water present in the resole resin.
Bij een werkwijze voor het persen van samen in een mal gespo-10 ten phenolische hars, glasvezel en zure katalysatoren stelt het belgisch octrooi no. 847449 voor om tegelijk ook een hydrofiel anorganisch materiaal toe te passen, zoals CaS04 hemi-hydraat of B2O3.In a process for pressing molded phenolic resin, glass fiber and acid catalysts together in a mold, the Belgian patent no. 847449 proposes to simultaneously use a hydrophilic inorganic material, such as CaSO4 hemi-hydrate or B2O3.
Voor kant en klare perscompounds zoals in onderhavige aanvrage bedoeld biedt deze gedachte echter geen uitkomst daar een waterontrekkend mid-15 del de viscositeitsstabiliteit van de compound zelf zou beïnvloeden.However, for ready-made press compounds as referred to in the present application, this idea offers no solution, since a water-extracting agent would influence the viscosity stability of the compound itself.
De uitvinding heeft tot doel een thermohardende samenstelling op basis van phenolische resolharsen te verschaffen die bovenvermelde nadelen vermijdt en daardoor geschikt is om als perscompound gebruikt te worden.The object of the invention is to provide a thermosetting composition based on phenolic resole resins which avoids the above-mentioned drawbacks and is therefore suitable for use as a press compound.
20 Volgens de uitvinding wordt daartoe in een thermohardende samenstelling op basis van phenolische resolhars, vulstof en basische condensatie katalysatoren en eventueel indikkingsmiddel(en), glasvezel en verder gebruikelijke additieven voor tenminste een gedeelte van de vulstof een waterbindend middel toegepast dat pas bij een temperatuur 25 boven 50eC wezenlijk waterbindend is.According to the invention, in a thermosetting composition based on phenolic resole resin, filler and basic condensation catalysts and optionally thickener (s), glass fiber and further usual additives, a water-binding agent is used for at least a part of the filler which only at a temperature above 50eC is substantially water-binding.
Dergelijke thermohardende samenstellingen worden volgens de 8401570 -2- ;? Λ.Such thermosetting compositions are described in accordance with the 8401570-2-; Λ.
uitvinding bij voorkeur toegepast als perscompounds, zoals met name "Bulk Molding Compounds" (BMC), "Dough Molding Compounds" (DMC) of "Sheet Molding Compounds" (SMC).The invention is preferably used as press compounds, such as in particular "Bulk Molding Compounds" (BMC), "Dough Molding Compounds" (DMC) or "Sheet Molding Compounds" (SMC).
Dergelijke verwerkingstechnieken zijn o.a. beschreven tijdens de 5 voordrachten van de ”13e Offentliche Jahrestagung der Arbeits- gemeinschaft Versterkte Kunststoffen” gehouden van 5 t/m 7 oktober 1976.Such processing techniques have been described, among others, during the 5 presentations of the “13th Offentliche Jahrestagung der Arbeitsgemeinschaft Versterkte Kunststoffen” held from 5 to 7 October 1976.
De thermohardende harssamenstellingen volgens de uitvinding bevatten bij voorkeur ten minste 25 gew.%, berekend op de phenolisch 10 resolhars, van het waterbindend middel dat pas boven 50°C wezenlijk waterbindend is.The thermosetting resin compositions according to the invention preferably contain at least 25% by weight, based on the phenolic resole resin, of the water-binding agent which is essentially water-binding only above 50 ° C.
Een zeer geschikt waterbindend middel om volgens de uitvinding toe te passen is gips anhydriet (CaS04. o H2O).A very suitable water-binding agent for applying according to the invention is gypsum anhydrite (CaSO4. O H2O).
Gipsanhydriet wordt volgens de uitvinding bij voorkeur in een 15 verhouding van tenminste 50 gew.% ten opzichte van de phenolische resolhars toegepast.According to the invention, gypsan hydrite is preferably used in a ratio of at least 50% by weight to the phenolic resole resin.
Additieven in perscompounds volgens de uitvinding omvatten bijvoorbeeld verdere vulstoffen zoals mergel, kwartsmeel, millicarb (vulstof van de firma Plüss Staufer AG), talk, enz.; indikkingsmid-20 delen zoals MgO, epoxyharsen, enz.; lossingmiddelen zoals calciumstearaat, ACMOS (lossingsmiddel van de firma Tietjen & CO.); en verder gebruikelijke additieven.Press additive additives according to the invention include, for example, further fillers such as marl, quartz flour, millicarb (filler from Plüss Staufer AG), talc, etc .; thickeners-20 parts such as MgO, epoxy resins, etc .; release agents such as calcium stearate, ACMOS (release agent from Tietjen &CO.); and further conventional additives.
Als basische condensatie katalysator kan zeer geschikt gebruik gemaakt worden van alkalimetaalhydroxyden en/of carbonaten.Alkali metal hydroxides and / or carbonates can very suitably be used as basic condensation catalyst.

De compound is nog min of.meer "vloeibaar" - te vergelijken met cementmortel.The compound is more or less "liquid" - comparable to cement mortar.
Op een SMC machine wordt m.b.v. een doctor blade een dunne 25 laag compound op een voortgetrokken polytheen folie uitgesmeerd. Vervolgens wordt via een snij-inrichting glasroving (30 gew.% glasvezel, berekend op het compoundgewicht) hierop uitgestroöid, waarna een tweede laag compound die ook op een polytheen folie is opgebracht hier boven op komt. De zo ontstane "sandwich" van compoundglasvezel en com-30 pound wordt met een aantal aandrukwalsen en een aandrukband verder verdicht zodat de glasvezels door de hars bevochtigd worden. Aan het eind van de machine wordt de sheet -nog steeds ingepakt in de polytheen folies - opgerold.On an SMC machine, using a doctor blade spread a thin 25 layer compound on a drawn polythene foil. Glass roving (30% by weight of glass fiber, calculated on the compound weight) is then spread on top via a cutting device, after which a second layer of compound, which is also applied on a polythene foil, is superimposed on top. The resulting "sandwich" of compound glass fiber and composite material is further compacted with a number of pressure rollers and a pressure tape so that the glass fibers are wetted by the resin. At the end of the machine, the sheet - still packed in the polythene foils - is rolled up.
