Abstract: A resin coating is bonded to a metal base by treating a clean surface of the base with an oxidising agent, a metal powder and a resin, at least the treatment with the resin being effected at a temperature above the fusion temperature of the resin.  The surface may be contacted with a composite coating comprising the oxidising agent, the metal powder and the resin, at least the oxidizing agent being in intimate contact with the surface, and the contacted surface is heated to a temperature above the fusion temperature of the resin. The surface may be treated with an oxidising agent; and is thereafter heated to above the fusion temperature of the resin and contacted with a mixture of resin powder and metal, or a dilute solution of the resin is applied to the surface and the surface is then heated to above the fusion temperature of the resin and whilst at this temperature, the metal powder is applied on the fused resin surface and the resin powder is applied thereon.  The clean surface may be heated above the fusion temperature of the resin; at which temperature resin which has been treated with a solution of an oxidising agent and dried, is applied and metal powder is applied to the resin, or at which temperature metal powder which has been treated with a solution of an oxidising agent and dried, is applied and resin is applied to the metal powder.  The oxidising agent may be chromic acid, molybdic and/or vanadic acid.  The treated base may be allowed to cool, or may be heated to above the fusion temperature of the resin and resin is applied thereto, e.g. from a fluidized bed. The resin may be a chlorinated polyether or a fluorocarbon resin. The coating material may be applied as an aqueous or solvent dispersion of particles and fused into a coherent layer, by dipping the heated metal into a loosely settled bed of thermoplastic powder, by contacting the heated metal with a bed of powder in a state of aeration intermediate that of a fluidised bed and the loosely settled powder, or by spraying the heated metal with thermoplastic powder. The thermoplastic material may be nylon, chlorinated polyethers and fluorocarbon resins, e.g. polytrifluorochloroethylene.  the metal may be aluminium, iron and steel, other metals and alloys.  The metal surface may be cleaned by blasting or pickling.  The metal powder may be of aluminium, silver, copper, nickel, iron, chromium, antimony, tin, molybdenum, or palladium.

Patent GB-579942-A (GB)
Title: Improvements in or relating to laminated material and to fuel containers comprising the same
IPC: C08L29/14
Filed: 1944-04-03
Abstract: Laminations of butadiene copolymers, e.g. Hycar, are bonded together by an adhesive composition comprising a polyvinyl butyral wherein the combined butyraldehyde is between 20.7 per cent and 44.0 per cent by weight (i.e. 30-80 per cent substitution of hydroxyl groups) and a substantially insoluble infusible polyhydric phenol-aldehyde resin. Suitable resins having solubilities in the solvent employed of 1-10 per cent are prepared by polymerization, at 125 DEG  C. or less, of resorcinol, phloroglucinol, orcinol or one of the naturally occurring polyhydric phenols such as the tannin extracted from the bark of the quebracho tree, with formaldehyde, paraformaldehyde, acetaldehyde, furfural or aldol dissolved in an organic solvent. .5-1.5 per cent by weight of sodium or potassium hydroxide is added as catalyst. Polyvinyl butyral is preferably prepared from polyvinyl alcohol which is substantially free of any ester groups.  The solvent-free adhesive composition should contain 25-60 per cent of the polyvinyl butyral although the proportion between 30 per cent and 45 per cent is preferred.  The copolymer of acrylonitrile and butadiene when used as a fuel tank member may be mixed or compounded with pigments, fillers, plasticisers, accelerators, stabilizers, dispersing agents, ageing registers or sulphur.  Copolymers of butadiene and either styrene or isobutylene are also instanced.  The polyvinyl butyral and resin-forming ingredients in the composition are applied to the copolymer stock by spraying, brushing or doctoring and allowed to dry, the temperature at one stage in the drying preferably being raised to 65 DEG  C. or higher to polymerize the resin.  This polymerization may, however, be left until the structure is heated to cure the compounded butadiene copolymer.  The curing temperature may range from 80-160 DEG  C.  A pressure of 100 lbs./sq. in. is applied in bonding the materials, but lower pressures of 5-10 lbs./sq. in. are mentioned as reasonably satisfactory.  In one example, a mixture of the polyvinyl butyral, resorcinol, formalin, sodium hydroxide, methanol and water is applied as a layer .0005 in. thick to Hycar, a compounded acrylonitrile-butadiene polymer, dried for a few minutes, and a further sheet of Hycar applied to the coated surface.  The whole assembly is heated at 135 DEG  C. for 40 minutes.  A further similar coating of the resin composition may be applied to one of the surfaces of the assembly and cured.  A Hycar coated side of a textile fabric may be applied to the composition coated Hycar sheet and cured, the other side of the textile fabric carrying a thin lamina of natural compounded rubber which unites readily with the sealant agent of self-sealing fuel tanks.

Abstract: Clear, permanently refusible zinc-calcium resinates are made by a process comprising dissolving a rosin in a solvent, adding a carboxylic acid soluble in resin at the reaction temperature or a salt thereof capable of reacting with abietic acid to liberate the acid, adding 5-15 per cent by weight of zinc oxide (or equivalent hydroxide) based on the weight of the rosin, heating to complete the reaction between the rosin and the zinc compound, adding 1-55 per cent hydrated lime before or after adding the zinc compound, and heating to complete the reaction.  The concentration of the rosin may be 50 per cent or more, the solvent may be distilled off from the reaction product, and the reaction temperature may be 100 DEG -150 DEG  C.  Heat-treated rosins prepared from gum or wood rosin according to Specification 351,583 may be used, or polymerised rosins obtained by use of zinc chloride, sulphuric acid, or boron trifluoride, or according to Specification 536,218.
