| titleOfInvention | Epoxy modified alkyd resins |
| abstract | An epoxy modified alkyd resin, capable of being infinitely diluted with water and suitable for use as a paint or varnish vehicle, is made by (1) heating an oil modified alkyd with a dicarboxylic acid or anhydride to obtain a partial ester with residual acidity (2) cooling the partial ester, (3) adding a water-miscible solvent and an epoxidized ester derived from a fatty oil to the cooled composition, (4) effecting a partial reaction between the epoxy compound and the partial ester and (5) inhibiting further reaction by neutralizing residual acidity of the partial ester with a volatile neutralizing agent. Upon heating the resultant resin, the neutralizer is driven off and curing of the resin takes place. In examples the alkyd resins were made by reacting (a) phthalic anhydride or tetrahydrophthalic anhydride, (b) maleic anhydride (optional), (c) pentaerythritol, glycerol, a mixture of trimethylol ethane and sorbitol or a mixture of pentaerythritol and ethylene glycol and (d) pelargonic acid, coconut fatty acids, tall oil fatty acids, soyabean fatty acids, linseed fatty acids, dehydrated castor oil fatty acids or an alcoholysis product of soyabean oil and pentaerythritol. Other alkyd forming components mentioned are polypentaerythritols, diethylene glycol and butanediol; cottonseed, corn, soyabean, rapeseed, safflower, castor, dehydrated castor, linseed, coconut, menhaden, sardine, whale, cod, tallow, or lard fatty oil; and caproic, caprylic, capric, lauric, myristic, palmitic, stearic, behenic, oleic, erucic, linoleic, arachidonic and clupadonic acids. The alkyd resin-forming reaction may be effected in the presence of a solvent, e.g. diethylene glycol diethyl ether. The dibasic compound with which the alkyd is condensed may be phthalic, tetrahydrophthalic, hexahydrophthalic, monochlorophthalic, tetrachlorophthalic or chlorendic anhydride. The water-miscible solvent may be denatured alcohol, or the monomethyl-, monoethyl-, or monobutyl-ethers of ethylene glycol or diethylene glycol. The epoxy compound may be an epoxidized oil containing 5-12% oxirane oxygen (e.g. epoxidized linseed, soyabean, safflower or fish oils), epoxidized linseed fatty acid ester, epoxy-stearyl epoxy stearate, butyl epoxy-stearate, octyl epoxy-behenate, methyl di-epoxy stearate, propyl tri-epoxy stearate or allyl epoxy-stearate. The volatile neutralizing agent may be ammonia, an alkyl amine containing 1-5 carbon atoms, dipropylamine, diisopropylamine, triethylamine, monoethanolamine, diethanolamine, dimethylethanolamine, diethylethanolamine, morpholine or N-methyl morpholine. The resins may be admixed with other water-soluble or water-dispersible resins, e.g. phenol-formaldehyde, melamine-formaldehyde, butylated melamine-formaldehyde, silicon, butadine-styrene or acrylic resins. Pigments such as titanium dioxide or a mixture of brown iron oxide, china clay and lithophone may be added. Specification 921,623 is referred to. |
