Abstract

The process involves crushing the waste and scrap material (I), together with any stripped metal, to give material (A) with particle size 60-700 microns, mixing with unsatd. polyester resin (B) or a mixt. (C) of resin (B) and styrene, pelletising the mixt. and moulding in a hydraulic press at elevated temp. and pressure. Also claimed is a mixt. of 10-70% (A) and 90-30% resin (B) (with polymerisation hardeners, accelerators, retarders etc.), or of 10-70% (A), 10-30% styrene and 60-20% resin (B). USE/ADVANTAGE - The process enables complete recycling of the above waste prods. (I) (instead of disposal by burning), to give new prods. contg. less styrene than the original prods., using smaller amts. of hardeners etc. as above. The new prods. are useful in the motor industry (roof lining, sound insulation etc.) and in the timber prods. and furniture industries etc.

Description

Es ist bekannt, daß die Abfälle und Ausschußteile von mit gehärtetem ungesättigtem Polyester beschichteten Filz- und Juteerzeugnissen bisher kein gebräuchliches Verfahren zur Wieder­ verwendung haben. Die Entsorgung dieser Erzeugnisse ist ein großes Problem, da diese zur Zeit nur durch Verbrennung erfolgt. Aber die Verbrennung von Styrol und styrolischen Verbindungen entwickelt zahlreiche Gase, die die Atmosphäre verschmutzen und somit belasten. Bisher wurden nur Erzeugnisse aus SMC (Sheet Molding Compound) wiederverwendet.It is known that the waste and rejects from hardened unsaturated polyester coated felt and So far, jute products have not been a common method of reuse have use. The disposal of these products is a big problem, because this is currently only done by combustion. But the burning of styrene and styrenic compounds develops numerous gases that pollute and pollute the atmosphere thus burden. So far, only products from SMC (Sheet Molding Compound).

Gegenstand der Erfindung ist ein Verfahren nach den Ansprüchen 1 und 2, in dem Abfälle und Ausschußteile von mit gehärtetem ungesättigtem Polyester beschichteten Filz- und Juteerzeugnissen mit entfernten metallischen Teilen, nach einer Zerkleinerung in Schneide-, Schlag- und Prallmühlen bis zu einer Korngröße von 60-700 µm mit einem frischen ungesättigten Polyesterharz oder einer Mischung von ungesättigtem Polyesterharz und Styrol behandelt werden. Das Polyesterharz enthält Zusätze für die Polymerisierung (Härter, Beschleuniger, Verzögerer usw.). Die so erzielte Mischung wird in einer Tablettieranlage in einem Temperaturbereich von 20-80°C tablettiert. Die Formmasse oder die Tabletten werden in einer Presse für Duroplastmaterialien (Temperaturbereich 120-160°C und Druck 100-400 bar) gepreßt. Die mit der Erfindung erzielten Vorteile bestehen insbesonders darin, daß die mit gehärtetem ungesättigtem Polyester beschich­ teten Filz- und Juteabfälle und Ausschußteile hundertprozentig wiederverwendet werden können und somit die Verbrennung dieser Erzeugnisse vermieden werden kann. Die auf diese Weise erzielten neuen Produkte enthalten weniger Styrol als die initiellen Erzeugnisse. Der Verbrauch von Polyester und von Zusätzen (Härter, Beschleuniger, Verzögerer usw.) ist geringer.The invention relates to a method according to the claims 1 and 2, in which waste and rejects from with hardened unsaturated polyester coated felt and jute products with metal parts removed, after shredding in Cutting, impact and impact mills up to a grain size from 60-700 µm with a fresh unsaturated polyester resin or a mixture of unsaturated polyester resin and styrene be treated. The polyester resin contains additives for the Polymerization (hardener, accelerator, retarder, etc.). The mixture thus obtained is in a tabletting plant in tabletted in a temperature range of 20-80 ° C. The molding compound or the tablets are in a press for thermoset materials (Temperature range 120-160 ° C and pressure 100-400 bar) pressed. The advantages achieved with the invention are in particular in that the coated with hardened unsaturated polyester felt and jute waste and rejects 100 percent can be reused and thus burning them Products can be avoided. The achieved in this way new products contain less styrene than the original ones Products. The consumption of polyester and additives (hardener, Accelerator, decelerator, etc.) is lower.

Die Verwendung der erfindungsgemäßen Teile kann in der Autozu­ lieferindustrie (Autohimmel, Geräuschabschirmung usw.) und in anderen Industrien (Holz, Möbel usw.) erfolgen. The use of the parts according to the invention can in the Autozu supply industry (car headlining, noise shielding, etc.) and in other industries (wood, furniture, etc.).

Die Mischung erfolgt in einem Kneter. Die so erzielte Mischung wird danach bei Raumtemperatur und 200 bar in einer Tablettieranlage tablettiert. Das Ergebnis des Tablettiervorganges, die Tabletten, werden in einer hydraulischen Presse in Form einer Platte (oder in einer anderen gewünschten Form) gepreßt. Parameter: Temperatur 140°C, Druck 200 bar, Preßzeit 80 Sek.2000 g jute coated with hardened unsaturated polyester Waste is crushed up to a grain size crushed from 60-240 µm. The regrind is with a Composition of 1500 g unsaturated polyester resin, 11.40 g retarder, 0.70 ml lubricant, 12.90 ml hardener, 7.50 ml accelerator and 300 g filler mixed. The mixture takes place in a kneader. The mixture thus obtained is then tabletted at room temperature and 200 bar in a tableting system. The result of the tableting process, the tablets, are in a hydraulic press in the form of a plate (or in a other desired shape) pressed.
