Description

Verfahren zur Herstellung von Schirmen für Leuchten aus lichtdurchlässigen Papierblättern Es sind Schirme für Leuchten bekannt, die aus Schichten von lichtdurchlässigen Papierblättern bestehen, die von Hand über einer Form zusammengeklebt sind. Die bisher zum Verkleben der einzelnen Schichten verwendeten Lösungen von Kunstharzen sind ungünstig, weil die flüchtigen Lösungsmittel nachteilig auf die Gesundheit der Arbeitenden einwirken. Es werden zwar auch wasserlösliche Klebemittel verwendet, doch ergeben Kunstharzklebemittel mit ' flüchtigen Lösungsmitteln härtere und wasserunempfindlichere Schirme als wasserlösliche Klebemittel. Das Verfahren nach der Erfindung vereinigt nun die Vorteile der Verwendung von Kunstharzklebemitteln mit wäßrigen ,und flüchtigen Lösungsmitteln, während ihre Nachteile vermieden werden. Es besteht darin, daß die zum Schirm geformten Papierblätter mittels einer Dispersion von feinem Kunstharzpulver in Wasser aufeinandergeklebt werden - wobei ein geringer Teil des Pulvers in Lösung geht und die Klebung bewirkt - und daß die Papierblätter anschließend getrocknet und durch Spritzen oder Tauchen mit einem flüchtigen Harzlösungsmittel überzogen oder getränkt werden. Gesundheitliche Schädigungen sind dabei leicht durch bekannte Vorkehrungen, z. B. durch Arbeiten im Abzug, auszuschalten. Dem flüchtigen Lösungsmittel können auch durchscheinende- oder durchsichtige Kunstharze beigemengt sein, wenn man auf den Schirmen eine Harzd.eckschicht erzielen will. Das Lösungsmittel dringt in den Schirm ein und löst die aus der wäßrigen Dispersion übriggebliebenen Harzteilchen auf, so daß eine die ganze Schi:r.mdicke gleichmäßig durchsetzende Harzlösung entsteht, die nach dem Verdunsten des Lösungsmittels, z. B. unter einem Abzug, fest wird. Ist in dem Lösungsmittel Harz gelöst, so entsteht auf der Schirmoberfläche eine Harzhaut, die mit dem Schirm unlösbar verbunden ist.Process for the production of shades for lights from translucent Sheets of paper There are known shades for lights, which consist of layers of translucent Sheets of paper are glued together by hand over a form. the Solutions of synthetic resins previously used to bond the individual layers are unfavorable because the volatile solvents are detrimental to health of the workers. Although water-soluble adhesives are also used, however, synthetic resin adhesives with volatile solvents are harder and less sensitive to water Umbrellas being water-soluble adhesives. The method according to the invention combined now the advantages of using synthetic resin adhesives with aqueous, and volatile Solvents while avoiding their disadvantages. It is that the Sheets of paper formed into a screen by means of a dispersion of fine synthetic resin powder are glued together in water - with a small part of the powder in solution goes and causes the gluing - and that the paper sheets then dried and coated with a volatile resin solvent by spraying or dipping or be soaked. Damage to health is easily known Precautions, e.g. B. by working in the fume cupboard. The volatile solvent translucent or transparent synthetic resins can also be added, if you want to achieve a resin top layer on the umbrellas. The solvent penetrates into the screen and dissolve the resin particles left over from the aqueous dispersion so that a resin solution is created that is uniformly penetrating the entire length of the boat, after evaporation of the solvent, e.g. B. under a fume cupboard, becomes solid. If resin is dissolved in the solvent, a will appear on the screen surface Resin skin that is inextricably linked to the screen.
