Description

COMPOSITION NETTOYANTE ET/OU DECAPANTE A BASE D'ESTER DE DIACIDE ET DΕTHER CLEANING AND / OR STRIPPING COMPOSITION BASED ON DIACID ESTER AND DΕTHER
La présente invention concerne une composition permettant à la fois de décaper des revêtements par exemple à base de peinture et de nettoyer des objets salis par des huiles ou des graisses.The present invention relates to a composition making it possible both to strip coatings, for example based on paint, and to clean objects soiled with oils or greases.
Les premières compositions décapantes et dégraissantes du type ci-dessus étaient à base de chlorure de méthylène et ou de trichloro-1 ,1 ,1 éthane (T.1.1.1.) (voir par exemple US.-A. 2.507.983 et DE-A. 2.524.752). De telles compositions présentent l'avantage d'être efficaces et peu coûteuses.The first stripping and degreasing compositions of the above type were based on methylene chloride and or on trichloro-1, 1, 1 ethane (T.1.1.1.) (See for example US.-A. 2.507.983 and DE-A. 2.524.752). Such compositions have the advantage of being effective and inexpensive.
Toutefois, de telles compositions peuvent causer des dommages à l'environnement et plus particulièrement à la couche d'ozone (protocole de Montréal visant l'arrêt de l'utilisation du T.1.1.1 normalement à fin 1995).However, such compositions can cause damage to the environment and more particularly to the ozone layer (Montreal protocol aimed at stopping the use of T.1.1.1 normally at the end of 1995).
Un progrès important a été apporté par le remplacement de ces solvants chlorés, soit par des lactames ou des lactones dont les plus usuels sont la N-méthyl-2- pyroolidone ou la gamma-butyrolactone (US.-A. 4.120.810), soit par un mélange de diester d'alkyie de diacides qui est un sous-produit de l'industrie de production de monomères nécessaires à la préparation des polyamides (DE-3.438.399).Significant progress has been made by replacing these chlorinated solvents, either with lactams or lactones, the most common of which are N-methyl-2-pyroolidone or gamma-butyrolactone (US.-A. 4.120.810), or by a mixture of alkyl diester of diacids which is a by-product of the industry for the production of monomers necessary for the preparation of polyamides (DE-3,438,399).
Les compositions ci-dessus ne sont pas toujours adaptées au décapage de revêtements de différente nature tels que peintures à l'eau, peintures à l'huile, laques, vernis et résines plastiques, et surtout ne sont pas efficaces à la fois pour le décapage des revêtements et le nettoyage d'objets divers pour enlever les huiles et les graisses.The above compositions are not always suitable for the stripping of coatings of different nature such as water paints, oil paints, lacquers, varnishes and plastic resins, and above all are not effective for both stripping coatings and cleaning of various objects to remove oils and greases.
La présente invention a pour but de proposer une composition qui soit précisément efficace à la fois pour le décapage et pour le nettoyage. Elle a également pour but de proposer une composition du type ci-dessus quiThe object of the present invention is to provide a composition which is precisely effective both for pickling and for cleaning. It also aims to propose a composition of the above type which
.selon une variante puisse être exempte de solvants..a variant may be free of solvents.
Elle a également pour but de proposer une composition du type ci-dessus qui soit stable au stockage au moins un an.It also aims to propose a composition of the above type which is stable on storage for at least one year.
Ces buts et d'autres sont atteints par la présente invention qui concerne en effet une composition décapante et/ou de nettoyage comportant en volume : a) 1 à 90% d'au moins un ester de dialkyle en C1-C4 d'au moins un diacide aliphatique en C4-C6. b) 99 à 1 % d'au moins un éther choisi parmi les éthers présentant :These aims and others are achieved by the present invention which in fact relates to a stripping and / or cleaning composition comprising by volume: a) 1 to 90% of at least one C1-C4 dialkyl ester of at least a C4-C6 aliphatic diacid. b) 99 to 1% of at least one ether chosen from ethers having:
- un point éclair supérieur à 5°C - au moins un groupe méthoxy par molécule- a flash point higher than 5 ° C - at least one methoxy group per molecule
- une masse molaire inférieure à 200. La composition selon l'invention contient donc au moins 1 à 90% en volume, de préférence 10 à 80% d'un ester de dialkyle en C1-C4 d'au moins un diacide aliphatique en C4-C6.- a molar mass less than 200. The composition according to the invention therefore contains at least 1 to 90% by volume, preferably 10 to 80% of a C1-C4 dialkyl ester of at least one C4-C6 aliphatic diacid.
Le mélange d'esters de diacides sont des esters dérivés essentiellement des acides adipiques glutariques et succiniques, les groupes alkyles de la partie ester étant surtout choisis parmi les groupes méthyle et éthyle, mais pouvant être également propyle, isopropyle, butyle, n-butyle et isobutyle.The mixture of diacid esters are esters derived essentially from glutaric and succinic adipic acids, the alkyl groups of the ester part being especially chosen from methyl and ethyl groups, but which can also be propyl, isopropyl, butyl, n-butyl and isobutyl.
Comme on l'a indiqué ci-dessus, les diacides en C4 à Ce ci-dessus sont en fait les sous-produits de la préparation de l'acide adipique qui est un des monomères principaux des polyamides, et les esters de dialkyle sont obtenus par estérification de ce sous-produit qui contient généralement en poids de 15 à 30% d'acide succinique, de 50 à 75% d'acide glutarique et de 5 à 25% d'acide adipique.As indicated above, the C4 to Ce diacids above are in fact the by-products of the preparation of adipic acid which is one of the main monomers of polyamides, and the dialkyl esters are obtained by esterification of this by-product which generally contains by weight from 15 to 30% of succinic acid, from 50 to 75% of glutaric acid and from 5 to 25% of adipic acid.
Les esters de diacide sont des produits qui se trouvent dans le commerce. Comme produits commerciaux, on peut citer plus particulièrement le Rhodiasolv RPDE® commercialisé par la Société Rhône-Poulenc et le "Du Pont Dibasic Esters®" commercialisé par la Société Du Pont de Nemours.Diacid esters are commercially available products. As commercial products, there may be mentioned more particularly Rhodiasolv RPDE® marketed by the company Rhône-Poulenc and "Du Pont Dibasic Esters®" marketed by the Company Du Pont de Nemours.
La composition selon l'invention contient également en volume de 99 à 1 %, de préférence de 90 à 20% en poids d'au moins un éther choisi parmi les éthers présentant : - un point éclair supérieur à 5°C au moins un groupe méthoxy par molécule un masse molaire inférieur à 200. Comme éther utilisable dans les compositions selon l'invention on peut citer : 1 -ter-butoxy-2-méthoxyéthane, anisole, 1 ,4-diméthoxybenzèπe, éthylène glycoldiméthyléther, 1 ,2-diméthoxybenzène, 2-méthoxy-1 ,3-dioxolane, diéthylèneglycoldiméthyléther, 1 ,2,3-triméthoxybenzène,The composition according to the invention also contains in volume from 99 to 1%, preferably from 90 to 20% by weight of at least one ether chosen from ethers having: - a flash point higher than 5 ° C at least one group methoxy per molecule a molar mass of less than 200. As ether which can be used in the compositions according to the invention, there may be mentioned: 1-ter-butoxy-2-methoxyethane, anisole, 1,4-dimethoxybenzèπe, ethylene glycoldimethyl ether, 1,2-dimethoxybenzene , 2-methoxy-1, 3-dioxolane, diethylene glycoldimethyl ether, 1, 2,3-trimethoxybenzene,
1 ,3-diméthoxybenzène. Les compositions selon l'invention peuvent contenir en outre au moins l'un des produits ci-dessous. c) Au moins un solvant hydrocarboné liquide, aliphatique ou aromatique et inodore et présentant un point éclair supérieur à 40°C de préférence supérieur à 70°C de telle sorte que ce solvant ne soit pas classé dans les liquides inflammables.1, 3-dimethoxybenzene. The compositions according to the invention may also contain at least one of the products below. c) At least one liquid hydrocarbon solvent, aliphatic or aromatic and odorless and having a flash point greater than 40 ° C, preferably greater than 70 ° C so that this solvent is not classified in flammable liquids.
Des exemples de tels solvants dérivés du pétrole et à point éclair élevé, sont notamment les spirits minéraux tel le white spirit et les naphtas. Comme produits commerciaux, on peut utiliser dans les compositions selon l'invention l'ISOPAR® d'Exxon, le SOLTROL® de Shell et les solvants HI-SOL® d'Ashland. On recommande d'utiliser de 10 à 100 volumes, de préférence de 30 à 60 volumes de c) pour 100 volumes de a) + b). On peut aussi citer les composés présentant une chaîne hydrocarbonée aliphatique, saturée ou comprenant au moins une insaturation, substituée par au moins un radical du type alkyle, aryle ou alkylaryle. Plus particulièrement, la chaîne aliphatique comprend 3 à 12 atomes de carbone, et de préférence, 4 à 10 atomes de carbone, ces valeurs sont données en prenant en compte la chaîne hydrocarbonée la plus longue de la molécule, substituants exceptés. Selon une variante, la chaîne hydrocarbonée aliphatique est substituée par deux groupements aryle et/ou alkylaryle.Examples of such solvents derived from petroleum and with a high flash point, are in particular mineral spirits such as white spirit and naphthas. As commercial products, the compositions according to the invention can be used ISOPAR® from Exxon, SOLTROL® from Shell and HI-SOL® solvents from Ashland. It is recommended to use 10 to 100 volumes, preferably 30 to 60 volumes of c) per 100 volumes of a) + b). Mention may also be made of the compounds having an aliphatic hydrocarbon chain, saturated or comprising at least one unsaturation, substituted by at least one radical of the alkyl, aryl or alkylaryl type. More particularly, the aliphatic chain comprises 3 to 12 carbon atoms, and preferably 4 to 10 carbon atoms, these values are given taking into account the longest hydrocarbon chain of the molecule, substituents excepted. According to a variant, the aliphatic hydrocarbon chain is substituted by two aryl and / or alkylaryl groups.
Plus particulièrement, le radical aryle comporte 6 atomes de carbone, et le radical alkylaryle correspond à un noyau aromatique substitué par au moins un groupement alkyle, de préférence en C--C4. Dans un tel cas, la liaison entre le substituant alkylaryle et la chaîne hydrocarbonée aliphatique du composé peut avoir lieu par l'intermédiaire de l'un des carbone de la partie alkyle de ce composé, ou, de préférence directement par l'un des atomes de carbone du noyau aromatique.More particularly, the aryl radical has 6 carbon atoms, and the alkylaryl radical corresponds to an aromatic ring substituted by at least one alkyl group, preferably C - C4. In such a case, the bond between the alkylaryl substituent and the aliphatic hydrocarbon chain of the compound can take place via one of the carbon atoms of the alkyl part of this compound, or, preferably directly through one of the atoms of aromatic nucleus.
Comme cela a été indiqué, la chaîne aliphatique hydrocarbonée du composé peut en outre comprendre au moins un radical alkyle, comportant plus particulièrement 1 à 4 atomes de carbone, le groupement méthyle étant préféré.As has been indicated, the aliphatic hydrocarbon chain of the compound may also comprise at least one alkyl radical, more particularly comprising 1 to 4 carbon atoms, the methyl group being preferred.
