Definitions
- This invention relates to paint compositions and, in particular, heterochromatic, or multicoloured paint compositions and to methods of their manufacture.
- the invention also relates to the novel use of certain ingredients in the manufacture of paint compositions.
- AAMc Aqueous Multicolour
- European Patent Application No. 91830148.2 also describes an AAMc paint which comprises a pigmented base dispersed in a precipitating solution containing borate ions.
- AAMc paint which comprises a pigmented base dispersed in a precipitating solution containing borate ions.
- conventionally known heterochromatic paint formulations use borax or borate ions.
- such formulations are disadvantageous in that they produce large inelastic fleck paints which are undesirably very textured.
- problems with prior art systems include, inter alia, (i) particles drying to give a highly textured finish;
- This present invention provides a water based alternative to current solvent/water based systems whilst maintaining the pattern and texture previously only obtainable using solvent/water based systems.
- the paint compositions described herein contain less than 0.1% Volatile Organic Compound (VOCs) and are therefore extremely safe to use, are virtually odour free and are not harmful to the environment.
- VOCs Volatile Organic Compound
- a paint formulation comprising at least a thickener adapted to increase in elasticity at pH greater than 7.
- the increase in elasticity occurs at between pH 7 and 9, e.g. pH 8.
- a preferred thickener for use in the formulation of the invention is a cationic guar gum and preferably one which is treated so as to be soluble only under acidic conditions.
- Such gums include galactomannan gums and particularly a galactomannan gum which is not completely solubilised.
- the galactomannan gum is preferably a specially treated gum such that the gum is only soluble under acidic conditions.
- a pH of less than 8 in particular a neutral or acidic pH then the gum behaves in a thixotropic manner.
- the rheology becomes elastic.
- the gum is preferably treated by coating it to increase the time before the gum dissolves.
- a preferred gum which may be mentioned is JAGUAR C-13S available from Rhone Poulenc in the UK. Although other gums may be used such as GUAR CAT 10, N- HANCE 3205, these are found to be not quite as suitable as the JAGUAR gum.
- a paint formulation as hereinbefore described comprising an inner phase which is adapted to increase in elasticity and an outer phase.
- such a two phase paint formulation comprises an inner phase adapted to produce a multicolour effect and is thixotropically soluble at low pH and substantially elastic at high pH; and an outer, high pH phase.
- the inner and outer phases can preferably be charged.
- a paint formulation comprising an inner phase adapted to produce the multicolour effect and which is cationically charged and an outer phase which is anionically charged.
- the charged phases are particularly advantageous in that they can keep separate the individual particles and prevent transfer of colourant between them.
- a preferred paint formulation is one in which the inner phase comprises JAGUAR C13 S.
- a paint formulation as hereinbefore described comprising; an inner phase comprising a delayed solubility cationic guar gum thickener, a dispersant, a pigment and a polymer emulsion; and
- an outer phase comprising a sequestering agent and a second thickener, which second thickener may be anionic.
- the ratio of the inner phase to the outer phase may be from 1 :99 to 75:25, preferably from 5:95 to 66:33. An especially preferred ratio is 15:85.
- increased amounts of the polymer emulsion may be added to the fleck paint, thus for example, a mixture of fleck paint/polymer emulsion may be prepared in the ratio of from 75:25 to 95:5 fleck paint to polymer emulsion, preferably from 80:20 to 90: 10 and especially 85:15.
- the inner phase will be an aqueous phase and will generally comprise from 80 to 90 parts by weight (w/w) of water, e.g. 85 w/w water; from 1 to 2 w/w of a thickener, preferably from 1.5 to 2 w/w and especially, 1.75 w/w; from 0J to l .Ow/w of a dispersant, preferably from 0J to 0.6 w/w, e.g.
- the outer phase will generally comprise from 0J to 1 w/w of a sequestering agent, preferably from 0J to 0.7 w/w, more preferably from 0.5 to 0.1 w/w, e.g. 0.6; and from 0J to 2 w/w of a thickener, from 0.5 to 1.5 w/w of a thickener, e.g. 1 w/w.
- a sequestering agent preferably from 0J to 0.7 w/w, more preferably from 0.5 to 0.1 w/w, e.g. 0.6; and from 0J to 2 w/w of a thickener, from 0.5 to 1.5 w/w of a thickener, e.g. 1 w/w.
- preparation of an inner phase comprising at least one pigment and a thickener and adjusting the pH down to allow the guar gum thickener to solubilise; preparation of an outer phase comprising at least an aqueous medium of pH greater than 7; and
- the process of the invention comprises;
- pigments may be used although the preferred pigment is titanium dioxide.
- the inner phase can be tinted to produce any colour. If a pigment is omitted, pearlescent dispersions can be added to produce metallic effects.
- the outer phase may be pigmented.
- such pigmentation may mask the colour of the flecks pigmented in the inner phase.
- it is preferable that the pigmentation is in the inner phase only.
- tinted base paints used in the invention can utilise conventional amounts of coloured dispersions known per se.
- any conventionally known dispersants may be used, such as one or more acrylic polymers.
- the inner phase thickener may be a galactomannan gum or a blend of galactomannan gums, which gums will be cationic.
- the polymer emulsion may, for example, be a polymeric dispersion of copolymers of vinyl acetate and ethylene in water.
- Conventionally known acidifying agents may be used, for example, a carboxylic acid and similarly conventionally known neutralising agents may be used, for example, a hydroxide such as sodium hydroxide.
- the gellant may be a silicate such as anhydrous sodium lithium magnesium fluoro-silicate.
- the second thickener may be a cellulose, such as sodium salt of a cellulose ether.
- excipients may be included in the inner phase and/or the outer phase, such as a biocide, for example, a solution of n-formals and isothiazolones, may optionally be used in the mixture; similarly, a defoamer such as mineral oil may also optionally be used.
- a biocide for example, a solution of n-formals and isothiazolones
- a defoamer such as mineral oil may also optionally be used.
- the shape of the flecks produced can be controlled by the way the inner phase is added to the outer phase. If the inner phase is injected into the outer phase, thin string like particles are produced. Whereas, if the inner phase is, for example, simply poured into the outer phase and then mixed together, irregular shaped flecks of an even size are produced. This type of manufacture is mentioned in European Patent application No. 85196538.3.
- the polymer emulsion this does not require any coalescing solvent and therefore allows the formulation to be solvent free; and c) the dispersant, this should be highly effective and allow the pigment to be dispersed thoroughly and prevent it being flocculated by the guar gum.
- a cationic guar gum such as JAGUAR C13 S
- paint formulations are novel per se.
- a cationic guar gum treated so as to be soluble only under acidic conditions, in the manufacture of a paint formulation.
- formulations according to the invention may be applied using conventional methods however it is preferred that, in use, the paint would be applied using a spray gun.
- a method of applying a paint formulation according to the invention which comprises the use of a paint spray gun containing a paint formulation comprising an inner phase and an outer phase as hereinbefore described.
- the inner phase, or pigmented phase, consisted of the following ingredients:
- the inner phase is preferably tinted to produce the coloured particles, using aqueous pigment dispersions.
- Example la To an inner phase according to Example la) was added under slow speed mixing a black dispersion, yellow oxide disp., and blue dispersion.
- the polymer emulsion was added slowly to the fleck paint whilst under slow stirring until homogenous.
