Definitions

  • This invention relates to paint and stain formulations, in particular to paint formulations including petroleum-derived oils especially re-refined petroleum-derived oils.
  • Paints are liquids that solidify when exposed to air and are used to cover surfaces for decorative and protective purposes.
  • paints are formed by mixing a pigment and a liquid vehicle that solidifies when exposed to air and a solvent.
  • paint formulations consist of different categories of chemical compounds.
  • the vehicle ultimately forms the adherent, flexible, skin-like coating.
  • the pigment is dispersed throughout the vehicle and gives the final film its colour and hiding power.
  • the vehicle generally may be an unsaturated, or drying, oil, which is an ester formed from the reaction of a long-chain carboxylic acid, for example, linoleic acid, with a polyfunctional alcohol, such as glycerine; or it can be a synthetic polymer.
  • a long-chain carboxylic acid for example, linoleic acid
  • a polyfunctional alcohol such as glycerine
  • Linseed oil is a typical drying vehicle used in paints. On exposure to the oxygen in the ambient atmosphere, the unsaturated bonds of the hydrocarbon chain of the ester molecules making up linseed oil are attacked and an oxide, or ether, is formed thereby cross-linking one molecule to another. This results in a tough, insoluble macro molecule which becomes a polymer after being applied to an exposed surface.
  • the vehicle may also be a synthetic polymer, dissolved or dispersed in a suitable solvent, so that as the solvent evaporates the individual macro molecules come into contact and become enmeshed with one another.
  • the solidification may be improved by the presence in the solvent of a polymerisation catalyst, called a drier.
  • a polymerisation catalyst called a drier.
  • the types of synthetic polymers most widely employed as paint vehicles are alkyd resins, nitro ⁇ cellulose (in which cellulose is de-polymerised and the small molecules are nitrated, and the substance is then re- polymerised), phenolic resins, acrylic resins, epoxy resins, polyvinyl acetate resins, and polyurethanes.
  • Paint pigments are generally fine powders that either strongly scatter light, to yield a white effect or absorb certain wavelengths of light, producing a coloured effect.
  • Typical white pigments are inorganic oxides such as titanium dioxide, antimony oxide, and zinc oxide. Other white, insoluble, inorganic compounds may also be used. Coloured inorganic oxides may be used as coloured pigments as may a variety of organic solids.
  • the solvent or thinner for the drying oil paints is generally turpentine, which is a mixture of cyclic hydrocarbons containing ten carbon atoms, or the thinner may be mixture of suitably volatile hydrocarbons derived from petroleum distillates.
  • the solvent for most synthetic vehicles is generally a mixture of hydrocarbons, alcohols, ketones, or esters.
  • the non ⁇ volatile and non-drying solvent be absorbed by the substrate within a time short enough to resist wash-off by rain, say within 3 to 4 hours of the product being applied; the residual part of the paint product must stay in place and dry in the same or similar manner as a normal oil or alkyd paint and must have reasonable durability; a single applied coat should be sufficiently opaque to hide surface defects such as gum veins, iron stains, knots etc. as well as colour variations due to different stages of weathering; the product in the container must be readily reincorporated after storage and transport and retain a reasonable uniformity during use; advantageously, the cost of raw materials should be as low as possible to enable the product to compete in the existing market now dominated by water-borne fence finishes.
  • an alkyd resin-containing paint or stain formulation which comprises from 1 to 52.5% by weight of petroleum-derived oil, from 5 to 30% weight (solids) of alkyd resin vehicle, from 1 to 20% by weight of pigment(s), from 15 to 40% by weight of conventional paint solvent(s), if desired, from 10-20% by weight of gloss control agent, and optionally additives as normally used in paint or stain formulations.
  • the present invention provides a water-based alkyd resin-containing paint or stain formulation which comprises:- from 1 to 30% by weight of petroleum-derived oil, from 5 to 30% by weight (solids) of alkyd resin vehicle, from 0 to 20% by weight of pigments, from 0.5 to 10% by weight of emulsifier, balance water, and optionally additives as normally used in water-based paint or stain formulations.
  • the present invention provides a water- based petroleum-derived oil emulsion which comprises:- from 1 to 30% by weight of petroleum-derived oil, from 5 to 30% by weight (solids) of alkyd resin vehicle, from 0.5 to 10% by weight of emulsifier, balance water, and if desired, drying additives.
  • the present invention provides several methods of making a water-based alkyd resin-containing petroleum-derived oil emulsion.
  • Formulations according to the present invention include fence stains, surface paints for bare timber surfaces, or timber preservatives, with the natures and amounts of components being varied to meet requirements. Stain formulations will normally use a lower percentage of pigments than paint formulations.
  • formulations according to the present invention may have flash points significantly higher than known oil-based paints and stains.
  • the non-water based formulations according to the invention contain in excess of 30% by volume of petroleum- derived oil or recycled oil ("RBO").
  • petroleum-derived oil is meant an oil derived from petroleum which is generally useful for producing lubricants. This definition and the limitations on quantities present does not exclude the presence of other petroleum-derived products used for purposes such as thinning.
  • RBO used petroleum-derived oil which has been re- refined by:-
  • a typical RBO has the characteristics:-
  • the type of alkyd used according to the invention is preferably a long oil alkyd based on soybean oil.
  • the oil length is preferably from 50 to 90%.
  • References in the Examples to quantity of alkyd used refer: in the case of oil-based formulations to alkyd by itself; and in the case of water-based formulations to about one part alkyd resin solids to two parts latex resin solids, such latex resins being those conventionally used in the paint industry.
  • the emulsifiers used according to the invention are preferably ethylene oxide propylene oxide block copolymers or nonyl phenol ethylene oxide surfactants.
  • the R.B.O. emulsion is stabilised further using water soluble thickener.
  • Non-limiting examples of oil-based formulations according to the present invention include fence stains as follows:-
  • the alkyd resin used was a long-chain alkyd resin being 63% semi- drying oil penta alkyd with a 70% solids content in a high boiling hydrocarbon solvent, having a flash point above 61°C. Other alkyd resins may be used in substitution thereof.
  • the drier mixture used in the formulation was prepared from three driers as follows:
  • the metal content of the preceding four formulations, based on the alkyd oil was calculated to be: lead - 0.8%; cobalt - 0.1%; manganese - 0.1%;. These levels are typical for dark colour stains.
  • Exkin No. 2 methyl ethyl ketoxime is an anti-skinning agent used to promote stability of the formulations during storage and transport. Other similar anti-skinning agents may be substituted.
  • the method of preparation was essentially the same as for the MISSION BROWN Stain.
  • Water-based products according to the invention may be made in three steps:-
  • the vehicle is mixed with petroleum-derived or recycled petroleum-derived oil in the presence of an emulsifier
  • step 1 is emulsified with water
  • the emulsion is mixed with further water and filler and, if desired, pigments.
  • Bevaloid 643 .080g Bevaloid
  • Examples 13 to 17 illustrate a two-step process for making water- based products according to the invention:
  • This recipe is designed to check the effect of R.B.O. emulsion on colour, drying, hardness and enamel recoatability of gloss 100% acrylic.
  • the R.B.O. Emulsion was made by mixing:
  • Latex 50% non-volatile 280.0
