Verfahren zum Herstellen von Formkörpern aus einer Polyesterharzmasse Zusatz zum Patent 1008 487 Das Patent 1 008 487 betrifft ein Verfahren zum Herstellen von Formteilen durch Vergießen einer in der Kälte härtbaren Polyesterharzmasse, vorzugsweise von Polyestern auf der Grundlage von Maleinsäure bzw. Maleinsäureanhydrid in Styrol, welche die hochprozentige Lösung eines oder mehrer thermoplastischer Polymerer, wie Polystyrol, Polyvinylcarbazol, Polyvinyläther oder Polyisobutylen, in Styrol enthält.Process for the production of moldings from a polyester resin composition Addendum to Patent 1008 487 Patent 1 008 487 relates to a method of manufacturing of molded parts by casting a cold-curing polyester resin compound, preferably of polyesters based on maleic acid or maleic anhydride in styrene, which is the high percentage solution of one or more thermoplastic Polymers such as polystyrene, polyvinyl carbazole, polyvinyl ether or polyisobutylene, contains in styrene.
Durch den Gehalt der Polyesterharzmasse an einer Lösung eines polymerisierten Kunstharzes in Styrol wird verhindert, daß beim Aushärten der Polyesterharzmasse eine Schrumpfung auftritt. Nach dem Verfahren des Hauptpatentes kommt eine Polyesterharzmasse zur Anwendung, der entweder eine hochprozentige Lösung eines polymerisierten Kunstharzes in Styrol bzw. das polymerisierte Kunstharz in mehl-@ feiner Vermahlung zugesetzt ist, falls diePolyesterharzmasse bereits Styrol enthält ; erforderlichenfalls wird der Harzmasse Styrol zugesetzt, damit das thermoplastische Polymere völlig in dem Styrol in Lösung geht. Due to the content of the polyester resin composition in a solution of a polymerized Synthetic resin in styrene is prevented from curing the polyester resin composition shrinkage occurs. The process of the main patent is followed by a polyester resin compound for application, which is either a high percentage solution of a polymerized synthetic resin in styrene or the polymerized synthetic resin added in flour @ fine grinding if the polyester resin composition already contains styrene; if necessary, will Styrene added to the resin composition so that the thermoplastic polymer is completely in the Styrene goes into solution.
Bekanntlich löst sich Polystyrol bis zu 40°/0, Polyvinylcarbazol bis zu 8 /o, Polyvinyläther bis zu 30''/o und Polyisobutylen bis zu 8 bis 10°to in Styrol. It is known that polystyrene dissolves up to 40%, polyvinyl carbazole up to 8 / o, polyvinyl ether up to 30 '' / o and polyisobutylene up to 8 to 10 ° to in styrene.
Gemäß dem Hauptpatent wird ferner die Anwendung einer mit Füllstoffen wie Kaolin oder Kreide versetzten Polyesterharzmasse vorgeschlagen. Zur Erzielung bestimmter Eigenschaften der Formteile wird die gleichzeitige Anwendung verschiedener in Styrol löslicher thermoplastischer Polymerer empfohlen. According to the main patent, the use of one with fillers such as kaolin or chalk mixed polyester resin compound proposed. To achieve certain properties of the molded parts is the simultaneous use of different thermoplastic polymer soluble in styrene is recommended.
Es wurde gefunden, daß nach dem im Hauptpatent aufgezeigten Wege sich Formteile aus einer Polyesterharzmasse, die mit einem Füllstoff bzw. einem Füllstoffgemisch sowie mit der Lösung eines polymerisierten Kunstharzes in Styrol versetzt sind, auch auf dem Wege des Pressens herstellen lassen, wenn man den Füllstoff bzw. ein Füllstoffgemisch zunächst mit einer Polyesterharzmasse benetzt, die die Lösung eines thermoplastischen Kunstharzes in Styrol enthält, dann die benetzten Füllstoffe durch Pressen verformt und die durch Pressen hergestellten Formteile aushärten läßt. Wenn es erwünscht ist, daß der Formkörper eine gewisse Elastizität aufweist, ist es zweckmäßig, eine Polyesterharzmasse anzuwenden, die zusätzlich in Styrol neben einem thermoplastischen Kunstharz noch Kautschuk gelöst enthält. It has been found that according to the route shown in the main patent molded parts made of a polyester resin compound with a filler or a A mixture of fillers and a solution of a polymerized synthetic resin in styrene are offset, can also be produced by pressing if you have the filler or a filler mixture initially wetted with a polyester resin compound that the Solution of a thermoplastic synthetic resin in styrene, then the wetted Fillers deformed by pressing and the molded parts produced by pressing let harden. If it is desired that the molded body have a certain elasticity has, it is appropriate to use a polyester resin composition, which in addition In addition to a thermoplastic synthetic resin, it also contains rubber dissolved in styrene.
Eine bevorzugte Ausführungsform des Verfahrens der Erfindung besteht in der Anwendung einer Polyesterharzmasse, die eine hochprozentige Lösung von Polystyrol in Monostyrol enthält. A preferred embodiment of the method of the invention is in the application of a polyester resin compound, which is a high percentage solution of polystyrene in monostyrene.
Als Füllstoffe eignen sich für die Zwecke der Erfindung Asbestfaser, Quarzmehl, Quarzsand, kieselsäurefreie Füllstoffe, wie Korund, Rutil (Titandioxyd und Schwerspat), wie aber auch geeignete Mengen der vorstehend angegebenen thermoplastischen Kunstharze in Form von Mehl bzw. Grieß. Als ein zweckmäßiges Mengenverhältnis von Füllstoff zu Polyesterharzmasse haben sich 88 Gewichtsteile Füllstoff und 12 Gewichtsteile Polyesterharzmasse erwiesen. Suitable fillers for the purposes of the invention are asbestos fibers, Quartz powder, quartz sand, silica-free fillers such as corundum, rutile (titanium dioxide and heavy spar), as well as suitable amounts of the thermoplastics specified above Artificial resins in the form of flour or semolina. As a convenient proportion of Filler to polyester resin mass has 88 parts by weight of filler and 12 parts by weight Proven polyester resin compound.
Das Verfahren der Erfindung führt zu Formteilen, die unmittelbar nach dem Pressen aus den Formen herausgenommen werden können, ohne daß die Härtung bereits vollständig ist, so daß sich mit einer Presse verhältnismäßig sehr hohe Leistungen erzielen lassen. Die gehärteten Formteile zeichnen sich durch eine ungewöhnlich hohe Druckfestigkeit aus. Die erhaltenen Formteile weisen weder eine Schrumpfung noch eine Wärmespannung auf. The method of the invention leads to molded parts that are immediately after pressing can be removed from the molds without hardening is already complete, so that it is relatively very high with a press Let achievements. The hardened moldings are characterized by an unusual high compressive strength. The molded parts obtained show neither shrinkage still a thermal tension.
Ausführungsbeispiel 88 Gewichtsteile einer Mischung von 10 bis 20 °/0 Asbestfaser, 25 bis 40 °/0 Quarzmehl, 25 bis 28 °/0 Quarzsand, 3 bis 0°/0 grießförmiges Polystyrol mit einer Korngröße bis 1 mm werden mit 12 Gewichtsteilen einer Polyesterharzmasse (handelsübliche Harzmasse, vgl. R ö m p p, » Chemie-Lexikona, 3. Auflage, S. 1423, rechte Spalte, letzter Absatz), die Polystyrol in Monostyrol gelöst sowie Benzoylperoxyd als Katalysator enthält, benetzt. Dieses Gemisch wird gepreßt und die gepreßten Formteile durch Stehenlassen ausgehärtet. Die erhaltenen Formteile haben nach dem Aushärten eine Druckfestigkeit von 900 bis 1000 kg/cm2. Embodiment 88 parts by weight of a mixture of 10 to 20 ° / 0 asbestos fiber, 25 to 40 ° / 0 quartz powder, 25 to 28 ° / 0 quartz sand, 3 to 0 ° / 0 gritty Polystyrene with a grain size of up to 1 mm are mixed with 12 parts by weight of a polyester resin composition (commercially available resin compound, see R ö m p p, »Chemie-Lexikona, 3rd edition, p. 1423, right column, last paragraph), the polystyrene dissolved in monostyrene and benzoyl peroxide Contains as a catalyst, wetted. This mixture will pressed and the pressed molded parts cured by leaving to stand. The molded parts obtained have a compressive strength of 900 to 1000 kg / cm2 after hardening.
Zum Nachweis des synergistischen Effektes wurden drei Proben mit
gleichem Polyester-Styrol-und Katalysatorgehalt sowie gleicher Füllstoffmenge, jedoch
verschiedenen Füllstoffmischungen hergestellt.
Die Probe 2 enthält als Füllstoff lediglich 16, 5°/o Polystyrol ; sie ergab beim Aushärten eine Schrumpfung von 2, 1%. Sample 2 contains only 16.5% polystyrene as filler; it resulted in a shrinkage of 2.1% on curing.
Die Probe 3 enthält den gesamten Füllstoffanteil in Form mineralischer Füllstoffe Eine Polyesterharzmasse dieser Zusammensetzung zeigt beim Aushärten eine durchschnittliche Schrumpfung von 0, 61 °/o. Sample 3 contains the entire filler content in the form of mineral Fillers A polyester resin composition of this composition exhibits a average shrinkage of 0.61 per cent.
