Description
Verwendung von Acetessigsäureestern als Zusatzbeschleuniger für Polyesterform- und Überzugsmassen Gegenstand des Patentes Nr. 481<B>157</B> ist die Ver wendung von Acetessigsäureestern als Zusatzbeschleuni ger zu Polyesterform- und Überzugsmassen, die aus Ge mischen ungesättigter Polyester und daran anpolymeri sierbarer monomerer Äthylenverbindungen bestehen, und Hydroperoxid, vorzugsweise Ketonhydroperoxid, als Polymerisationskatalysator und ein Kobaltsalz als Beschleuniger enthalten und gegebenenfalls auf nicht viergrünend eingestellt sind, wobei man als Acetessig- säureester Verbindungen verwendet, die ein- oder mehr fach den Acetessigsäureesterrest CH3-CO-CH2-CO-O-R- an OH,
Äthersauerstoff, -CH=CH- oder Stickstoff ge bunden enthalten, wobei R eine Kohlenwasserstoffkette mit bis zu 3, vorzugsweise 2, Kohlenstoffatomen be deutet.
Es wurde nun gefunden, dass in gleicher Weise wie die vorgenannten Verbindungen auch solche Acetessig- säureesterverbindungen wirksam sind, die ein- oder mehrfach den Acetessigsäureesterrest an ein Schwefel atom gebunden enthalten.
Gegenstand der Erfindung ist daher die Verwendung von Acetessigsäureestern, die ein oder mehrfach den Acetessigsäureesterrest CH3-CO-CH2-CO-O-R- enthalten, wobei R eine Kohlenwasserstoffkette mit bis zu 3 Kohlenstoffatomen bedeutet, als Zusatzbeschleuni ger zu Polyesterform- und Überzugsmassen, die aus Ge mischen ungesättigter Polyester und daran anpolymeri sierbarer monomerer Äthylenverbindungen bestehen, und Hydroperoxid, vorzugsweise Ketonhydroperoxid, als Polymerisationskatalysator und .ein.
Kobaltsalz als Be- schleuniger enthalten und gegebenenfalls auf nicht ver- grünend eingestellt sind, dadurch gekennzeichnet, dass man solche Acetessigsäureester anwendet, bei denen der Acetessigsäureesterrest an ein Schwefelatom gebunden ist.
Als Beispiele für derartige Verbindungen seien die Acetessigsäureester des Thiodiglykols und seiner Homo logen genannt.
<I>Beispiel</I> a) Herstellung des Polyesters Ein durch Kondensieren von 152 Gewichtsteilen Maleinsäureanhydrid, 141 Gewichtsteilen Phthalsäure- anhydrid und 195 Gewichtsteilen Propandiol-1,2 her gestellter, durch Zusatz von 0,045 Gewichtsteilen Hy drochinon stabilisierter, ungesättigter Polyester mit der Säurezahl 47 wird 65%ig in Styrol gelöst.
b) Herstellung des Lackansatzes 100 Gewichtsteile dieses Polyesters werden mit 20 Gewichtsteilen Styrol verdünnt. Die Lösung wird als dann mit 1,5 Gewichtsteilen Kobaltnaphthenatlösung in Toluol (Co-Gehalt 2,2 Gewichtsprozent), 0,1 Gewichts prozent Paraffin (Smp. 52-.53 C) und gegebenenfalls 1,5 Gewichtsprozent Diacetessigsäureester des Thiodi- glykols versetzt.
c) Verarbeitung des Lackansatzes Der Lackansatz wird mit 500 g/qm auf ein helles Holzfurnier aufgetragen, das zuvor mit einem alkalisch aktivierten Bleichmittel gebleicht und mit 100 g/qm Aktivgrund beschichtet wurde. Der Aktivgrund besteht aus einem aus einer Lösung von 30 Gewichtsteilen Nitrocellulose (butanolfeucht), 120 Gewichtsteilen Äthylacetat, 35 Gewichtsteilen Butylacetat und 20 Ge- wichtsteilen Cyclohexanonperoxidpulver (95%ig) ent standenen Überzug.

Use of acetoacetic acid esters as an additional accelerator for polyester molding and coating compounds The subject of patent no. 481 <B> 157 </B> is the use of acetoacetic acid esters as additional accelerators for polyester molding and coating compounds that are made from mixtures of unsaturated polyesters and monomers that can be polymerized onto them Ethylene compounds exist, and contain hydroperoxide, preferably ketone hydroperoxide, as a polymerization catalyst and a cobalt salt as an accelerator and are optionally set to not four-greening, whereby the acetoacetic acid ester used is compounds which one or more times the acetoacetic ester residue CH3-CO-CH2-CO- OR- to OH,
Ethereal oxygen, -CH = CH- or nitrogen contained bound, where R is a hydrocarbon chain with up to 3, preferably 2, carbon atoms be.
It has now been found that, in the same way as the abovementioned compounds, acetoacetic acid ester compounds are also effective which contain the acetoacetic acid ester residue bound one or more times to a sulfur atom.
The invention therefore relates to the use of acetoacetic esters which contain one or more times the acetoacetic ester radical CH3-CO-CH2-CO-OR-, where R is a hydrocarbon chain with up to 3 carbon atoms, as additional accelerators for polyester molding and coating compositions made from Ge mix unsaturated polyester and anpolymeri sierbaren monomeric ethylene compounds exist, and hydroperoxide, preferably ketone hydroperoxide, as a polymerization catalyst and .ein.
Contain cobalt salt as an accelerator and are optionally set to non-greening, characterized in that acetoacetic acid esters are used in which the acetoacetic acid ester residue is bonded to a sulfur atom.
Examples of such compounds are the acetoacetic acid esters of thiodiglycol and its homologues.
<I> Example </I> a) Production of the polyester An unsaturated polyester, stabilized by the addition of 0.045 parts by weight of hydroquinone and stabilized by the addition of 0.045 parts by weight of hydroquinone, is produced by condensing 152 parts by weight of maleic anhydride, 141 parts by weight of phthalic anhydride and 195 parts by weight of 1,2-propanediol Acid number 47 is 65% dissolved in styrene.
b) Preparation of the paint batch 100 parts by weight of this polyester are diluted with 20 parts by weight of styrene. The solution is then mixed with 1.5 parts by weight of cobalt naphthenate solution in toluene (Co content 2.2 percent by weight), 0.1 percent by weight of paraffin (melting point 52-53 ° C.) and optionally 1.5 percent by weight of diacetoacetate of thiodiglycol .
c) Processing of the paint batch The paint batch is applied at 500 g / m² to a light-colored wood veneer that has previously been bleached with an alkaline-activated bleach and coated with 100 g / m2 of active primer. The active base consists of a coating made from a solution of 30 parts by weight of nitrocellulose (moist butanol), 120 parts by weight of ethyl acetate, 35 parts by weight of butyl acetate and 20 parts by weight of cyclohexanone peroxide powder (95%).
The table below shows the gel time and the stability of a varnish modified according to the invention in comparison with unmodified material.
