Definitions

• This invention relates to corrosion preventing compositions more especially for use for protecting wire, wire strands or wire ropes from corrosion.
• the present invention consists in a corrosion preventing composition
• a corrosion preventing composition comprising a dispersive medium and particulate material in the dispersive medium, in which the particulate material is provided with a coating of lead or a lead alloy or tin or a tin alloy.
• the specific gravity of the dispersive material may be about 1.1, with a possible variation of some 25% either way.
• the particulate material itself may be selected from a wide range of materials cheaper than lead and its specific gravity may be such as to ensure good suspension on the dispersive material.
• the particulate material is in the form of thin flakes or platelets and the following are the preferred materials for these platelets:
• Metal aluminium or its alloys magnesium or its alloys
• Organic polymer polyvinyl chloride, polyethylene, polypropylene, nylon, or the like
• Inorganic material mica, asbestos, vermiculite, or micaceous iron ore processed to a suitable condition and size that it will pass through a 200 mesh sieve.
• an uncoated particulate material from category (i) If an uncoated particulate material from category (i) is employed, its gravity will be such that it will tend to settle in the dispersive medium. However, if a material from category (ii) is employed, the specific gravity can range from as low as 0.90 to as high as 2.20; consequently, it is possible to select a material which will remain in suspension, even when coated with a thin film of metal such as lead. Likewise, the materials listed in category (iii) permit a similar combination.
• a dispersive medium there may be used any synthetic resinous material which, at room temperature, is a viscous fluid capable of controlled progressive polymerisation by blending with a suitable proportion of a reactive intermediate; specific examples of such an intermediate are (a) benzoyl peroxide, (b) an oil of vegetable origin such as linseed oil, or any oil possessing drying, or semi-drying properties.
• materials of animal origin which are capable of polymerisation, such as lanolin, may be employed. Such a mixture subsequently reacts to produce certain desirable physical and chemical characteristics.
• Grade R302 is an amber colored viscous liquid which flows slowly at 20 C. and comprises an oil modified heat hardening phenolic resin having a specific gravity at 25/25 C. of 0.98. Its viscosity at 25 C. diluted 2:1 wt./wt. with toluene is centistokes. It has an acid value of 34 mg. KOH/ g. and is soluble in benzene, toluene, xylene and drying oils.
• the particulate material is milled together with the coating agent in the ratio of 2-15 of coating agent by weight per unit weight of particulate material.
• a suitable particle size for the lead particles to be milled to form the surface coating is dust to 100 mesh with 0-200 mesh preferred.
• the preferred metal for the coating material is lead. Small additions of tin would improve the toughness of the metallic film without destroying its smear capacity, whilst antimony could materially improve the hardness.
• the minimum amount of coating metal is that which will produce a thin, but continuous, film to completely envelop the supporting agent, and this should not be less than 2% volume/ volume.
• the optimum percentage lies in the region of 5% of coating metal to of supporting agent, volume/volume.
• the most positive method of checking is by a colourmacroscopic technique.
• the colour check is achieved by employing a reagent which forms a brightly coloured, or distinctive, pigment when it reacts with the selected encapsulating metal or alloy. Then follows the macroscopic examination of a suflicient quantity of the material to ensure that encapsulation of the particles has been complete, and that the metallic agent has truly coated the supporting material, and not merely formed a dry dispersion.
• nylon powder has a white, almost crystalline appearance, but after milling has a grey appearance. If it is then treated with acidified Potassium Dichromate and elutriated with water, a continuous bright yellow film forms over all the particles, and proves quite readily that complete encapsulation has been achieved.
• the milling operation may be carried out by employing a ball mill, an end runner mill, or any such device which will produce a thin, continuous coating.
• the final operation-to produce the requisite protective and lubricating compound is to disperse the composite metal-flake in the preferred synthetic resin base by any appropriate means, usually in the presence of a small amount of organic solvent which facilitates the mixing operation.
• any appropriate means usually in the presence of a small amount of organic solvent which facilitates the mixing operation.
• Protective coatings applied in the manner described will give indefinite protection to ferrous surfaces in both acid and alkaline environments. They are of particular value in the manufacture, and subsequent dressing, of steel wire where the agent required to give protection of the wires against corrosion must, at one and the same time, function as a lubricant when the rope is subjected to dynamic loading.
• formulations of this nature are extremely stable over a wide range of temperatures, and have high adhesive powers. However, they may when necessary, be readily removed with a suitable solvent mixture, but are readily re-applied by brushing or spraying, thus permitting ready inspection and re-sealing of the underlying structure.
• Preferred sample compositions are as follows:
• Composition 2 Lead coated magnesium flake 20-30 24 Resin base 25-35 30 Microcrystalline wax, melting point 140- 170 F 5-10 7 Solvent (white spirit)--. 35-45 39 Composition 3:
• Lead coated organic powders in the form form of polymers e.g. polythene, polypropylene, P.V.C 20-30 24 Resin base 25-35 30 Microcrystall' 170 F 5-10 7 Solvent (White spirit) 35-45 39 Composition 4:
• Lead coated inorganic flake material e.g.
• a particulate organic material comprising thin flakes or platelets thereof which are coated with a thin homogeneous film of lead or a lead alloy or tin or a tin alloy which completely envelope the flakes or plateets.
• a corrosion preventing composition comprising thin flakes or platelets of inorganic material coated with a thin homogeneous film of lead or lead alloy or tin or tin alloy which completely envelopes the flakes or platelets, said coated flakes or platelets being in a viscous fluid comprising oil modified phenolic resin and an evaporable organic solvent.
• a corrosion preventing composition comprising thin flakes or platelets of organic or inorganic material other than lead or tin, said thin flakes are platelets being individually encapsulated by a thin continuous coating of lead, lead alloy, tin, or tin alloy, said encapsulated flakes or platelets being suspended in a dispersive medium comprising a polymerizable viscous fluid.
• a corrosion preventing composition as claimed in claim 4 in which the thin flakes or platelets are aluminium or aluminium alloy particles.
• a corrosion preventing composition as claimed in claim 14 in which the particles are of such a size that will pass through a 200 mesh sieve.
• a corrosion preventing composition as claimed in claim 3 in which the ratio by Weight of coating agent to flakes or platelets is in the range 2-15%.
• a corrosion preventing composition for the treatment of wire, wire strands and wire ropes the improvement wherein thin flakes or platelets of organic or inorganic material are first encapsulated with a thin coating of lead-or tin-containing smaller sized particles which is smeared or deformed with light pressure to produce a thin continuous film completely enveloping the individual flakes or platelets and after which the encapsulated flakes or platelets are dispersed in a viscous polymerizable fluid.
• poly- 15 merizable fluid comprises a synthetic resin which at room temperature is a viscous fluid capable of controlled progressive polymerization with an oil of vegetable origin.
