Definitions

  • the invention is in the field of photopolymerization and relates to new unsaturated aminosilane esters, a process for their preparation, a process for coating glass using the new esters and their use as photomers.
  • Esters of unsaturated carboxylic acids can polymerize in the presence of suitable starters and under the action of light (photopolymerization). This process is widely used in industry to coat hard surfaces.
  • a special area of application is the finishing of glass with the aim of giving the surface a milky, opaque appearance.
  • the known acrylic acid esters are usually mixed with silicates and then photopolymerized.
  • the disadvantage here is that the coating does not adhere very firmly and, particularly if the film has cracks, easily peels off again.
  • the object of the present invention was to provide new photomers which adhere better to the glass surface and thus overcome the disadvantages of the prior art.
  • the invention relates to new aminosilane esters which are obtained by reacting alk-oxylated polyols with unsaturated carboxylic acids of the formula (I), if appropriate
  • R 1 represents hydrogen or alkyl radicals having 1 to 4 carbon atoms
  • R 2 represents hydrogen or methyl
  • n represents 0 or numbers from 1 to 4
  • the resulting esters are then condensed with aminosilanes of the formula (II), OR 3
  • R 3 , R 4 and R 5 independently of one another represent alkyl and / or hydroxyalkyl radicals having 1 to 4 carbon atoms, and m represents numbers from 1 to 3.
  • the aminosilane esters resulting from the Michael reaction between the unsaturated carboxylic acid esters and the aminosilanes with the hydroxyl groups present on the glass surface enter into a covalent bond with the elimination of alcohol and thus adhere firmly.
  • the aminosilane esters are crosslinked via the double bonds contained in the molecule, which form a film on the glass surface that does not detach even if there is mechanical damage or cracking.
  • the invention further relates to a process for the preparation of aminosilane esters, in which optionally alkoxylated polyols are reacted with unsaturated carboxylic acids of the formula (I),
  • R 1 CH C- (CH 2 ) nCOOH (I)
  • R 1 represents hydrogen or alkyl radicals having 1 to 4 carbon atoms
  • R 2 represents hydrogen or methyl
  • n represents 0 or numbers from 1 to 4
  • the resulting esters are then condensed with aminosilanes of the formula (II)
  • R 3 , R 4 and R 5 independently of one another represent alkyl and / or hydroxyalkyl radicals having 1 to 4 carbon atoms, and m represents numbers from 1 to 3.
  • Polyols which are suitable for the purposes of the invention preferably have 2 to 15 carbon atoms and two to 6 hydroxyl groups. Typical examples are
  • Alkylene glycols such as, for example, ethylene glycol, diethylene glycol, triethylene glycol, propylene glycol, dipropylene glycol, tripropylene glycol, butylene glycol, hexylene glycol and polyethylene glycols with an average molecular weight of 100 to 1,000 daltons;
  • Methyl compounds such as, in particular, trimethylolethane, trimethylolpropane, trimethylolbutane, pentaerythritol, dipentaerythritol and neopentylglycol;
  • Lower alkyl glucosides in particular those with 1 to 8 carbons in the alkyl radical, such as methyl and butyl glucoside;
  • Sugar alcohols with 5 to 12 carbon atoms such as sorbitol or mannitol,
  • Aminosugars such as glucamine
  • hydrophilized polyols are used which are present as adducts of on average 1 to 10 and preferably 3 to 8 moles of ethylene and / or propylene oxide.
  • the adducts of 3 to 5 moles of ethylene or propylene oxide with glycerol or neopentyl glycol are particularly preferred.
  • the optionally alkoxylated polyols are esterified with acrylic acid, methacrylic acid or mixtures thereof. Because of the higher reactivity in photopolymerization, acrylic acid is preferably used. It is advisable to use the polyols and the carboxylic acids in a molar ratio of 1: 0.5 to 1: 1.5, based on the hydroxyl groups available in the polyol. If polyols with two hydroxyl groups are used, the conditions for the esterification, in particular the use ratio, will be chosen for reasons of application technology so that predominantly diesters are formed.
  • Aminosilanes are known substances which are available, for example, from Witco under the name Silquest® Silan A 1100 or A 1120. 3-aminopropyltrimethoxysilane is preferably used.
  • the polyol esters and the aminosilanes are preferably used in a molar ratio of 1: 2 to 2: 1. In particular that is Select ratio so that a sufficient number of double bonds remain in the resulting aminosilane ester so that photopolymerization can take place.
  • the new aminosilane esters contain double bonds which are amenable to photopolymerization. Another object of the invention therefore relates to the use of the esters as photomers. A final object of the invention is finally directed to a process for coating or matting, in which the new aminosilane esters are first applied to the glass surfaces, the layer thickness preferably being 1 to 10 and preferably 5 to 8 ⁇ m, and then the film in the presence developed by known photoinitiators by irradiation with light of a suitable wavelength and intensity, ie polymerized.
  • NPGPODA neopentyl glycol propoxylated di
  • Example 2 Analogously to Example 1, 79.1 g NPGPODA were reacted with 25.1 g 3-APTS.
  • GPTA glycerol propoxylated triacrylate
  • GPTA glycerol propoxylated triacrylate
  • Phln photoinitiator (irgacure 1173, Ciba-Geigy)

Abstract

L'invention concerne de nouveaux esters d'aminosilane. Pour obtenir lesdits esters, on fait réagir des polyols éventuellement alcoxylés avec des acides carboxyliques insaturés de formule (I), dans laquelle R1 représente hydrogène ou des résidus alkyle renfermant 1 à 4 atomes de carbone, R2 représente hydrogène ou méthyle, et n représente O ou un nombre compris entre 1 et 4; puis on condense les esters obtenus avec des aminosilanes de formule (II), dans laquelle R?3, R4 et R5¿ représentent indépendamment des résidus alkyle et/ou hydroxyalkyle renfermant 1 à 4 atomes de carbone, et m est un nombre compris entre 1 et 3. Ces esters peuvent être utilisés comme photomères pour le revêtement des surfaces de verre.
