Description

AQUEOUS AUTOXIDATIVELY DRYING ALKYD COMPOSITION
The present invention relates to an autoxidatively drying alkyd composition containing an emulsifier in the form of a curing alkoxylate of a monoethanolamide.
Alkyds have long been used as binders in paints and lacquers, and are employed in both professional and hobby painting, as well as in industrial lacquering. They may be the only binder used, as in air-drying paints, or be com- bined with e.g. amino resins, as is common in many stove- curing systems.
Alkyds are produced by condensation of a polybasic acid, a polyfunctional alcohol and a fatty acid. The poly- functional components form the coherent polymer skeleton, and the fatty-acid residues settle as tails on the skele¬ ton. Polyunsaturated fatty acids yield autoxidatively cur¬ ing, i.e. air-drying, binders, whereas saturated and only slightly unsaturated fatty acids yield alkyds for stove- curing. Even today, alkyds constitute the binder that is most commonly used in paints and lacquers. In recent years, however, environmental and health reasons have made it desirable to change from hydrocarbon-base to water-base paints, and the alkyd paints have thus lost market shares to latex paints, i.e. paints based on emul¬ sion-polymerised binders, such as polyacrylate and poly- vinyl acetate. This change has been especially pronounced in professional painting where the painters' health has always been a major problem. Thus, it is mainly the autoxidatively curing alkyds that have been affected. The solvent currently used in such paints is white spirit. Thus, the alkyd manufacturers have tried to adapt themselves to this development by making emulsions of alkyds. Accordingly, the alkyd is first produced in con- ventional manner, and is then emulsified in water. This requires the presence of a surface-active agent, usually in a content of 0.5-4% by weight of the finished paint. The surface- ctive agent acts as emulsifier, i.e. it con¬ tributes to the formation of droplets of the disperse phase and-it stabilises the structure by forming, on the droplets, an elastic surface film which reduces the ten- dency towards coalescence. With the right emulsifier, alkyd emulsions of long storage life can be obtained. Sur¬ face-active agents commonly used for this purpose are alkyl phenol ethoxylate and alcohol ethoxylate having HLB values in the range of 8-15. The HLB value (Hydrophilic Lipophilic Balance) is often used for indicating the amphiphilic nature of a surface-active agent.
The use of alkyds in emulsion systems eliminates the hazard of hydrocarbon emission from paints, but at the same time creates other inconveniences for the user. The emulsifier acts as an external plasticiser in the film of paint. Being surface-active and low-molecular, the emulsifier migrates to the air-paint film of the inter¬ face,- where it accumulates. As a result, the film becomes softer and its water and chemical resistance is impaired compared with a conventional white-spirit-base paint based on the same alkyd as the binder. Also, the presence of a surface-active agent tends to impair the clarity and gloss of the film, as well as its drying qualities.
Besides the development towards emulsion-base alkyd paints, intensive efforts are being made to produce micro- emulsions of alkyds and use these thermodynamically stable solutions as raw material. Thus, microemulsions constitute an alternative to emulsions when alkyds are to be intro¬ duced in a water-base system. Microemulsions differ from emulsions by being thermodynamically stable, i.e. having no tendency to separate when stored, which is a major advantage. However, the production of a microemulsion requires a much larger amount of surface-active agent than does the production of an emulsion. Thus, the emulsifier problems in the form of impaired film properties and reduced drying rate are especially pronounced in the case of alkyds used in paints. The present invention relates to a method for produc¬ ing aqueous emulsions and microemulsions of autoxidatively curing alkyds resulting in better film properties than has been the case with the prior-art techniques. The invention is based on the idea that the emulsifier employed is an alkoxylate of monoalkanolamide of drying carboxylic acids, i.e. compounds of the general formula:
O
R - C - NHCmH2m0 - (X)n - H (I)
wherein R is a polyunsaturated alkyl group having 7-23 carbon atoms, preferably 9-21 carbon atoms, X is an alky¬ leneoxy group derived from an alkylene oxide having 2-3 carbon atoms, m is 2-4, preferably 2, and n is 2-30, pre- ferably 3-20. The emulsifier usually amounts to 0.5-25% by weight of the prepared alkyd composition. If the alkyd composition is an emulsion, the amount of emulsifier pre¬ ferably is 1-5% by weight, whereas, if the alkyd composi¬ tion is a microemulsion, the amount of emulsifier prefer- ably is 5-20% by weight.
As to suitable carboxylic acids (RCOOH), wherein R has the meaning stated above, mention may be made of dried fatty acids, such as C-18 fatty acids containing two double bonds, e.g. 9,12-octadecadienoic acid (lino- leic acid) and 9,11-octadecadienoic acid (dehydrated ricinoleic acid), and C-18 fatty acids containing three double bonds, e.g. 9,12,15-octadecatrienoic acid (lino¬ lenic acid), 9,11,13-octadecatrienoic acid (eleostearic acid) and 4-keto-9,11,13-octadecatrienoic acid (licanic acid). Also longer polyunsaturated fatty acids, such as 5,8,11,14-eicosatetraenoic acid (arachidonic acid) and 5,8,11,14,17-eicosapentaenoic acid, can be used. For rea¬ sons of economy, one does not usually employ pure fatty acids, but mixtures derived from natural triglycerides. Suitable natural triglycerides include linseed oil, soya bean oil, tall oil, wood oil, sunflower oil and "fish oil. Dehydrated castor oil is another triglyceride that may conveniently be used.
The alkoxylate is produced e.g. by aminolysis of the corresponding triglyceride or methyl ester with a suitable 2-amino alkanol, followed by alkoxylation of the obtained amide in the presence of an alkaline catalyst at a tempe¬ rature of 150-180°C. Alkoxylation is preferably carried out in the presence of a tertiary amine lacking protons that react with alkylene oxide, or an alkylene-oxide- quaternised derivative of. the tertiary amine at a tempe¬ rature ranging from room temperature to 120°C, in which case high yields of the desired product can be obtained. Suitable tertiary amines include trimethylamine, triethyl¬ amine, tributylamine, dimethyloctylamine, tetramethylethy- lenediamine, dimethyl coconut amine, tristearyl amine, dimethyl piperazine and diazabicyclooctane. Alkoxylation may comprise ethoxylation, propoxylation, accumulation of propylene oxide and ethylene oxide in blocks, simultaneous addition of ethylene oxide and propylene oxide or a combi- nation thereof. The ethylene oxide conveniently amounts to at least 50 mole % of the added alkylene oxide. To use only ethoxylation is preferred.
Alkoxylation is carried out in such a manner that the emulsifier is given a suitable HLB value, usually 8-15. For a normal fraction containing polyunsaturated C-18 acids, e.g. derived from linseed oil, this corre¬ sponds, when only ethoxylation is used, to an addition of 3-18 moles of ethylene oxide per mole fatty acid mono- ethanolamine. It will be understood that the obtained ethoxylate always is a homologous mixture, since the alkoxylation, like most anionic polymerisation processes, results in a statistical distribution as to the degree of polymerisation.
The alkoxylate according to the invention undergoes autoxidative curing according to the same method as autoxidatively drying alkyds. If desired, the emulsifier according to the invention may also be combined with other surface-active agents or solubilisers, e.g. to improve the stability of the alkyd composition. Curing can be facili¬ tated by certain metal salts, in particular cobalt and manganese salts, so-called driers. Drier-containing emul- sions of drying alkyds with emulsifiers in the form of alkoxylates of the type described herein, result in a film which, when fully cured, does not contain any or only a slight amount of free alkoxylate. Thus, the autoxidatively curing alkoxylate is bonded in the network formed by the cured binder. Since no alkoxylate, or only a slight amount thereof, is present in the film, the latter has excellent properties as to e.g. hardness, gloss, clarity, water and chemical resistance. The drying properties are also pro¬ moted in that the alkoxylate participates in the curing process.
The invention will be further elucidated by the fol¬ lowing Examples.
Example 1 - Pigment paint based on an alkyd emulsion A glossy paint based on 53% by weight of an alkyd emulsion with a dry content of 60% and containing 20% by weight of titanium dioxide, was formulated with different emulsifiers in an amount of 3%.

The effect of the different emulsifiers on the film properties were esta¬ blished as to drying time, gloss, hardness and water resistance. The results are apparent from the Table below.
