Abstract
An organice chlorohydrocarbon-free paint- and varnish stripping and solvent cleaner compsn. comrpising (A) a resin solubiliser comprising one or more of methyl acetate, ethyl acetate, isopropyl acetate, butyl acetate, diethyl carbonate, ethylene carbonate, diethyl tartrate, triethyl citrate and gamma butyrolactone (B) a swelling agent chosen from one or more of ethylene glycol. propylene glyucol and/.or their low alkyl half-ethers and/or esters; (D) one or more surfactants chosen from alkylbenzene -sulphonates, (E) one or more thickeners chosen from alkylhydroxyalkylcelluloses and (F) one or more aprotic or non-aprotic polar dissolving assistants chosen from 1,2,3-trimethoxypropane, DMSO, DMF, methylformamide, DMAC, cyclo-hexanol, cycloheaxanone and 1,3-dimethoxypropan-2-ol. USE/ADVANTAGE - The compsn. can be used to remove all types of paint and varnish layers e.f. from wood, metal. brickwork, etc., in the form of mobile or stationary items e.g. for the purposes of cleaning, inspection, prepn. for repair, etc. They can be used in the form of an immersion bath for stripping suitable articles the compsn. is applied to the part to be stripped and subsequently stripping is carried out with a high press. water or steam jet. Since the comsns. are free from chlorinated hydrocarbons they are environmentally harmless and can be given a longer standing time to loosen the paint etc. due to the lower volatility of the ingredients.
Description
BESCHREIBUNG
Die vorliegende Erfindung betrifft ein organisches chlorkohlenwasserstofffreies Entschichtungs-, Löse- und Entlakkungsmittel zur Entfernung von Farb- und Lackschichten jeder Art von mobilen Gegenständen im Badverfahren sowie von stationären Objekten im Druckwasser- oder Dampfstrahlverfahren. Die vorgängige Entfernung solcher Schichten von mobilen Gegenständen und von stationären Objekten ist in vielen Fällen für Revisions-, Sanierungs- und Kontrollarbeiten erforderlich.
Bisher verwendete Entschichtungs-, Löse- und Entlakkungsmittel auf organischer Basis enthalten als unabdingbare Bestandteile chlorierte Kohlenwasserstoffe und/oder Solventnaphta, höhersiedende Alkylbenzole, Trimethylbenzole und Terpene.
So beschreibt die DE-PS 29 27 968 ein Mittel zum Entfernen von Farbmarkierungen, das u.a. mindestens 50 bis 60 Gew.-% chlorierte Kohlenwasserstoffe enthält.
Die DE-OS 25 24 752 betrifft ein Entlackungsmittel, das im wesentlichen aus einer Lösung von Essigsäure oder Chloressigsäure in vorzugsweise 40 bis 90 Gew.-% aliphatischen Chlorkohlenwasserstoffen besteht.
Die DE-AS 21 23 563 benennt ein Reinigungs-, Löseund Abbeizmittel auf der Basis organischer Lösungsmittel, die als Lösungsmittelkomponente u.a. alophatische, aromatische und/oder Halogenkohlenwasserstoffe enthalten können.
Die DE-OS 31 01 546 beschreibt demgegenüber ein Abbeizmittel auf wässriger Basis, mit Alkaligehalt.
Die europäische Patentanmeldung 85 163 betrifft ein Abbeizmittel zum Abbeizen von Lacken und Dispersionsfarben, das als polares Lösungsmittel, vorhanden in einem Anteil von 25 bis 70 Gew.-Teilen, Solventnaphta oder höhersiedende Alkylbenzole und/oder Terpene enthält, wobei bis zur Hälfte des gesamten Anteils an Lösemitteln z.B. durch 1,1, 1-Trichlorethan ersetzt sein kann, allerdings unter Inkaufnahme der Nachteile eines Chlorkohlenwasserstoffes ohne wesentliche Wirkungssteigerung.
Das USP 2 438 0 38 beschreibt bloss wässerige Lösungen von y-Butyrolacton.
Alle bisher verwendeten Mittel auf Basis chlorierter Kohlenwasserstoffe oder von Solventnaphta, höhersiedenden Alkylbenzolen, Trimethylbenzolen und Terpenen, weisen indessen die folgenden Nachteile auf: - starke Geruchsbelästigung infolge der grossen Verdunstungsgeschwindigkeit des Chlorkohlenwasserstoff-Anteils - starke Reizwirkung auf der Haut aus dem gleichen Grund - Gesundheitsgefährdung, insbesondere durch die wiederholt geäusserte Vermutung der Karzinogenität von Chlorkohlenwasserstoffen - nicht mehr akzeptable Umweltimmissionen durch Chlorkohlenwasserstoffe hinsichtlich Wasser, Boden und Luft - kurze Offenzeit von ca. 15 Minuten, infolge der grossen Verdunstungsgeschwindigkeit des Chlorkohlenwasserstoff-Anteiles, d.h. die Zeit zwischen dem Auftrag des Abbeizers und dem Abspritzen mit Wasser bzw.
dem Abstrahlen mittels Dampfstrahler ist sehr kurz und ermöglicht kein rationelles Arbeiten - beschränktes Wirkungsspektrum der Solventnaphta, höhersiedende Alkylbenzole und/oder Terpene enthaltenden Mittel bloss auf Olfarbanstriche, Kunstharzlacke und Dispersionen, unter Ausschluss von allen Zweikomponentensystemen, Einbrennlacken, Epoxylackierungen und vielen weiteren modernen Industrie- und Bautenanstrichen - Eintritt des Ablösens und Aufquellen des alten Farbanstriches bei den Solventnaphta, höhersiedende Alkylbenzole und/oder Terpene enthaltenden Mitteln erst nach einer bis mehreren Stunden nach dem Auftrag.
Demgegenüber liegt vorliegender Erfindung die Aufgabe zugrunde, ein organisches Entschichtungs-, Löse- und Entlackungsmittel zu liefern, das dank dem Gehalt an erfindungsgemässen Lösungsvermittlern sowohl den vorgenannten Mitteln als auch den in DE 34 38 399 beschriebenen Estergemischen deutlich überlegen ist und das ohne die vorerwähnten geruchsbelästigenden und gesundheitsschädlichen Komponenten auskommt, das zudem eine verringerte Umweltbelastung zur Folge hat und trotzdem alle heute bekannten Farbsysteme zum Aufquellen bis auf den Untergrund bringt sowie eine lange Offenzeit besitzt.
Diese Aufgabe wird bei einem organischen Entschichtungs-, Löse- und Entlakkungsmittel entsprechend der vorliegenden Erfindung durch die ausgewogene Mischung aus den Bestandteilen gemäss
Anspruch 1 - A Harzlöser, - B Quellmittel, - C Lösungsmittel für Tenside und Verdicker, - D Tensiden, - E Verdicker, gekennzeichnet durch den Gehalt an Lösungsvermittlern gelöst.
Es zeigt sich überraschenderweise, dass die erfindungsge mässen Chemikalien hervorragend als Komponenten insbe sondere zur Entlackung geeignet sind. Der vorliegenden Er findung liegt somit die neue, nicht zum bisherigen Stand der Technik gehörende Erkenntnis zugrunde, dass sich die als
Lösungsvermittler eingesetzten Bestandteile wie 1,2,3-Trimethoxypropan und/oder Dimethylsulfoxid und/oder Dimethylformamid und/oder Dimethylacetamid und/oder 1 ,3-Dimethoxypropan-2-ol die an sich gute Wirkung der Be standteile I-V gemäss Anspruch 1 sehr stark zu potenzieren vermögen. Sie sind auch Mitteln gemäss dem schon genannten USP 2 438 038, welche nur y-Butyrolacton als Hauptbe standteil enthalten, hoch überlegen.
Das erfindungsgemässe Chlorkohlenwasserstoff und Solventnaphta sowie höhersiedende Alkylbenzole und Terpene freie Entschichtungs-, Löse- und Entlackungsmittel weist folgende Vorteile auf: - keine Geruchsbelästigung - keine Reizung auf der Haut - stark reduzierte Gesundheitsgefährdung - geringstmögliche Umweltbelastung, da fast alle Inhaltsstoffe wasserlöslich und deshalb biologisch gut abbaubar sind - restlose Aufquellwirkung auf allen heute bekannten
Farbsystemen, inbegriffen Zweikomponenten-, Einbrennlack- und Epoxysystemen - lange Offenzeit, was eine rationelle, zügige Arbeitsge staltung ermöglicht.
Es zeigte sich zudem in überraschender Weise, dass die erfindungsgemässen Bestandteile sich nicht nur hervorra gend als Komponenten des Entlackungsmittels eignen, son dern dass bei richtiger Auswahl und Zusammensetzung ein gemäss Schweizerischem Giftgesetz giftfreies Produkt erhal ten werden kann.
Die Überlegenheit der vorliegenden Erfindung wird im folgenden durch Vergleichsversuche näher erläutert. Es wurden drei verschiedene Testflächen mit ausgewählten drei herkömmlichen Entschichtungs-, Löse- und Entlackungsmitteln A, B und C und dem erfindungsgemässen Mittel D behandelt und die Ergebnisse verglichen.

DESCRIPTION
The present invention relates to an organic chlorinated hydrocarbon-free decoating, solvent and degreasing agent for removing paint and varnish layers of all types of mobile objects in the bath process and of stationary objects in the pressurized water or steam jet process. The prior removal of such layers from mobile objects and from stationary objects is required in many cases for inspection, refurbishment and control work.
Previously used decoating agents, solvents and degassing agents on an organic basis contain chlorinated hydrocarbons and / or solvent naphta, higher-boiling alkylbenzenes, trimethylbenzenes and terpenes as essential components.
For example, DE-PS 29 27 968 describes a means for removing color markings, which among other things. contains at least 50 to 60 wt .-% chlorinated hydrocarbons.
DE-OS 25 24 752 relates to a paint stripper which consists essentially of a solution of acetic acid or chloroacetic acid in preferably 40 to 90% by weight of aliphatic chlorinated hydrocarbons.
DE-AS 21 23 563 names a cleaning, solvent and stripping agent based on organic solvents, which, among other things, as a solvent component. may contain alophatic, aromatic and / or halogenated hydrocarbons.
DE-OS 31 01 546, on the other hand, describes an aqueous-based paint remover with an alkali content.
European patent application 85 163 relates to a stripper for stripping paints and emulsion paints which, as a polar solvent, present in a proportion of 25 to 70 parts by weight, contains solvent naphtha or higher-boiling alkylbenzenes and / or terpenes, with up to half of the total proportion on solvents e.g. can be replaced by 1,1, 1-trichloroethane, but at the expense of the disadvantages of a chlorinated hydrocarbon without a significant increase in activity.
USP 2 438 0 38 describes only aqueous solutions of y-butyrolactone.
All previously used agents based on chlorinated hydrocarbons or solvent naphta, higher-boiling alkylbenzenes, trimethylbenzenes and terpenes, however, have the following disadvantages: - strong odor nuisance due to the high rate of evaporation of the chlorinated hydrocarbon component - strong irritant effect on the skin for the same reason - health hazard, in particular due to the repeated assumption of carcinogenicity of chlorinated hydrocarbons - unacceptable environmental emissions from chlorinated hydrocarbons with regard to water, soil and air - short open time of approx. 15 minutes, due to the high rate of evaporation of the chlorinated hydrocarbon content, ie the time between application of the stripper and spraying with water or
blasting with a steam jet is very short and does not allow for efficient work - limited spectrum of activity of the solvent naphtha, mediums containing higher-boiling alkylbenzenes and / or terpenes only on oil paints, synthetic resin lacquers and dispersions, with the exclusion of all two-component systems, stoving lacquers, epoxy lacquers and many other modern industrial and Architectural paints - Detachment and swelling of the old paint on solvent naphta, higher-boiling alkylbenzenes and / or terpenes containing agents only after one to several hours after application.
In contrast, the present invention has for its object to provide an organic decoating, solvent and paint stripping agent which, owing to the content of solubilizers according to the invention, is clearly superior to both the abovementioned agents and the ester mixtures described in DE 34 38 399, and that without the aforementioned odor-causing odors and harmful components, which also results in a reduced environmental impact and still brings all of the currently known paint systems to swell down to the surface and has a long open time.
This object is achieved in the case of an organic stripping, dissolving and draining agent according to the present invention by the balanced mixture of the components according to
Claim 1 - A resin solvent, - B swelling agent, - C solvent for surfactants and thickeners, - D surfactants, - E thickener, characterized by the content of solubilizers dissolved.
It has surprisingly been found that the chemicals according to the invention are particularly suitable as components, in particular for stripping. The present invention is therefore based on the new, not part of the prior art knowledge that the as
Components used as solubilizers, such as 1,2,3-trimethoxypropane and / or dimethyl sulfoxide and / or dimethylformamide and / or dimethylacetamide and / or 1, 3-dimethoxypropan-2-ol, increase the intrinsically good effect of the constituents IV according to claim 1 very strongly potentiate assets. They are also highly superior to agents according to the aforementioned USP 2,438,038, which contain only y-butyrolactone as the main component.
The chlorinated hydrocarbon and solvent naphtha according to the invention as well as higher-boiling alkylbenzenes and terpenes-free stripping, solvent and paint stripper have the following advantages: - no odor nuisance - no irritation on the skin - greatly reduced health risk - minimal environmental pollution, since almost all ingredients are water-soluble and therefore readily biodegradable are - complete swelling effect on all known today
Color systems, including two-component, stoving enamel and epoxy systems - long open time, which enables efficient, swift work design.
It was also shown, surprisingly, that the constituents according to the invention are not only outstandingly suitable as components of the paint stripping agent, but also that, with the correct selection and composition, a product which is non-toxic according to the Swiss Poison Act can be obtained.
The superiority of the present invention is explained in more detail below by comparison tests. Three different test areas were treated with selected three conventional stripping, solvent and paint stripping agents A, B and C and agent D according to the invention and the results were compared.
Comparison on test area I Horizontal car body panel, stove enamel per exposure assessment time A 30 minutes detachment of the top paint layer from the top coat, strong odor nuisance, partially already dried, which affects the depth effect and the repulsion or Ability to be emitted affects B no effect for 30 minutes C no effect for 30 minutes D the paint layer swells up to the base of the spatula
Comparison on test area 2 Horizontal wood, coated with oil varnish per exposure assessment time A 30 minutes. Removal of the top coat of paint from the top coat, strong odor nuisance, partially already dried, was the depth effect and the repulsion or
Ability to be emitted affects B 30 minutes of matting and roughening C 30 minutes of peeling off the top layer D 30 minutes of swelling of the entire paint layer down to the surface Comparison on test area 3 Vertically plastered wall, painted with acrylic exterior dispersion per exposure assessment product time A 30 minutes of peeling the top coat of paint from the top coat, strong odor nuisance, partially already dried, was the depth effect and the repulsion or
Radiability affects B 30 minutes of no attack C 30 minutes of matting the surface D 30 minutes of stripping of the entire paint layer down to the plaster base
The following were applied to test areas 1, 2 and 3 in layer thicknesses of 2 mm at 18 ° C.: the conventional paint stripper A, containing 74.9% by weight of chlorinated hydrocarbons according to the recipe in the methylene chloride leaflet from Chem.
Werke Hüls, Marl FRG, published in patent DE 34 38 399, the newer paint remover B, free from chlorinated hydrocarbons, but containing solvent naphtha and higher-boiling alkylbenzenes and terpenes, from the color factory Ca parol, Muttenz CH, with the brand name GRÜNER HAI, which is available from both Chlorinated hydrocarbons such as from solvent naphta,
higher-boiling alkylbenzenes and terpenes completely free paint stripping agent C from the patent DE 34 38 399 according to the recipe
12.0% by weight of diethylene glycol monobutyl ether
15.0% by weight dimethyl succinate 45.0% by weight dimethyl glutarate
6.0% by weight dimethyl adipate
2.0% by weight cellulose acetobutyrate (thickener)
5.0% by weight alkylbenzenesulfonate (soap content) 10.0% by weight sodium oleate
5.0% by weight of water, which as an ester mixture can be regarded as state of the art with regard to its composition for the present invention, while the aforementioned comparative examples A and B belong to the prior art with regard to their action, the agent D according to example 5 of the present invention.
It was found that the novel organic chlorinated hydrocarbon according to the invention, as well as solvent naphtha, higher-boiling alkylbenzenes and terpenes, free of stripping, solvent and paint stripping agents surprisingly compared to the agents known per se and corresponding to the prior art, on the one hand with regard to solvent and stripping action and spectrum of action and on the other hand with regard to Health risk and environmental emissions was superior.
