Title: Improvements in and relating to chlorinated maleic adduct-ethoxyline resinous compositions
IPC: C08G59/42
Filed: 1953-08-19
Abstract: An epoxy resin is cured and is rendered flameretardant by heating it with the Diels-Alder adduct of maleic anhydride and hexachlorocyclo pentadiene (i.e. hexachloroendomethylenetetrahydrophthalic anhydride).  The adduct may be employed in an amount ranging from about 5 to 70 per cent of the total weight of the resin and adduct. As an additional curing agent a dicarboxylic acid or anhydride (e.g. adipic acid or phthalic anhydride) may be used.  The acidic polyesters disclosed in Specifications 732,253, 735,531 and 738,660 may also be included in the composition.  The resin and the adduct may be dissolved in a solvent, e.g. acetone, cyclohexanone or methyl ethyl ketone with, if desired, benzene or toluene, and the solution used as a surface coating; as an adhesive; for impregnating cloth, paper, asbestos, mica or glass cloth; or for preparing laminated products (see Group VIII).  Fillers, e.g. titanium dioxide, clay, iron oxide, carbon, graphite, mica, wood flour or asbestos fibres may be coated by immersing them in the solution and evaporating the solvent (see Group III).  Moulded products may be prepared from a mixture of the resin, the adduct and a filler, and, if desired, a pigment, dye or lubricant, Magnets may be made by mixing the resin, the adduct and a powdered magnetic material (e.g. "Alnico") and moulding or casting the mixture (see Group XXXV).  Combination with other resins, e.g. alkyds, ureas or phenolics may be prepared. Examples are given describing the properties of various commercial epoxy resins, e.g. "Epon" or "Araldite" (Registered Trade Mark) cured with the adduct alone or in combination with phthalic anhydride.ALSO:A filter is coated by placing it in a solution of a mixture of an epoxy resin (see Group IV(a)) and a Diels-Alder adduct of maleic anhydride and hexachlorocyclopentadiene and thereafter evaporating the solvent.  The adduct acts to cure the resin and to render it flame-retardant.  Specified fillers are titanium dioxide, clays, iron oxide, carbon, graphite, asbestos fibres, finely divided mica and wood flour.
