Abstract
An aqueous acrylic resin coating composition containing iron oxide and especially suitable for application to fibre cement artefacts and masonry to form a surface coating having exceptional resistance to ultra violet light and water is essentially free from black iron oxide. Other metal compounds, including iron oxides such as red and yellow iron oxide may be selected for use in the composition, provided that they are all essentially free from black iron oxide either as an ingredient or as a contaminant.
Description
SURFACE COATING COMPOSITION
This invention relates to surface coatings particularly suitable for application to fibre-cement artefacts and/or to masonry. It will be understood in this present context that "fibre-cement" has its usual significance, namely cement-based products containing fibres as reinforcement. Typically such fibres are cellulose. The end product is commonly used as external cladding and/or roofing and must therefore be extremely weather-resistant.
It is well-known to treat fibre-cement artefacts in the form of flat and profiled sheets with a thin but relatively dense and heavily pigmented surface coating which not only serves to impart a desired decorative finish, but which also serves to protect the board material from the long term effects of exposure to light and water, especially where the reinforcing fibre component is cellulose. This surface coating treatment is normally done as a part of a factory manufacturing process, typically using aqueous resin compositions compounded with pigments and fillers and applied in known manner prior to curing in situ by application of heat.
Modern fibre-cement board products are very durable and have a projected lifespan on the order of 20-30 years or more. However it is desirable that a surface coating applied to the board shall itself exhibit at least comparable resistance to the environment. In this context, the resistance of the coating to the effects of ultra violet light and water is highly significant, because if the coating fails to provide adequate protection then the board material may suffer premature failure due to water ingress.
Known proposals for addressing the problems of water ingress include USP 5576062 which teaches the use of a styrene polymer film coating deposited ("cast") from organic solvent. This also lends itself to repair of surface damage, as the solvent component "re-melts" the resin component of the existing film coating and forms a new coherent resin film over the damaged area.
Whilst this approach may be effective, it requires the use of volatile organic solvent. The use of volatile organic solvent would be at best an undesirable complication in the context of a conventional manufacturing process based on aqueous resin coating compositions. It will be understood that "solvent-free" in the context of this specification refers specifically to volatile organic solvent, and not to the relatively minor amount of low volatility coalescing solvent normally used in such aqueous acrylic resin formulations. Such low volatility solvents are classed as "low VOC" .
A specific problem with known water-based surface coatings commonly used on fibre-cement artefacts is that their very long term response to exposure to ultra violet light and water is a progressive dulling of the initial surface gloss. This dulling appears as a matt effect and is accompanied by an increase in exposed surface area and ultimately by water penetration into the underlying board. Such water penetration usually results in the leaching-out of some of the lime component of the cement binder. Thus the desired long life of the fibre-cement board product may not be achieved without significant surface discolouration and/or damage.
The problem is particularly acute where relatively dark colours such as black and slate grey are involved. These are by far the most widely used colours, but it is believed to affect a significant proportion of all colours commonly used in the fibre-cement industry.
It follows that there is a need for an aqueous, organic solvent-free (as defined above) resin coating system which results in coatings of exceptional service life compared to known coatings and which does not require periodic patching-up or similar maintenance and furthermore which minimises any need to gain access to the coated surface. The latter may be particularly important where the coating is on a roof surface. Accordingly, it is an object of the present invention to provide a water-based coating with exceptional resistance to weathering, but without significant increase in either cost or formulation complexity.
According to the present invention, there is provided a surface coating composition comprising organic solvent- free aqueous acrylic resin and iron oxide, characterised in that the iron oxide component is essentially free from black iron oxide.
Other metal-based pigments including mixtures thereof may be included, as required for a particular colour finish and it should be understood that black iron oxide for the purposes of the present invention comprises ferric oxide, as will be discussed in more detail below.
The invention further provides a method of making coating compositions, the method being characterised by the step of compounding aqueous acrylic resin with iron oxide selected to be essentially free from black iron oxide. It also comprises coating materials made by this method, together with fibre-cement artefacts coated therewith.
It is emphasised that iron oxide is still used as a pigment in the manufacture of coating compositions according to the present invention. The iron oxide component may be any iron oxide, including for example yellow or red iron oxide, or mixtures of iron oxides, provided that no significant trace of black iron oxide is present. Pigments comprising metals such as copper, chromium, manganese, or titanium, including mixtures of these, may be included to achieve desired colour finishes, as long as these pigments are also essentially free from black iron oxide. However it is preferred that carbon black be not present, even though it is commonly used in domestic coating compositions where only the colour is important, and extreme service life is not required.
Surprisingly it has been discovered that the presence of even a very small amount of black iron oxide has a significant and completely unexpected effect on the very long-term resistance of cured aqueous acrylic resin coatings to ultra violet light and water. This discovery is particularly significant because black iron oxide is the preferred pigment in commercial coating formulations used for black and slate grey products.
It is noted that the prior art is entirely silent as to the criticality of black iron oxide in the context of surface coating life. The reason for this criticality is not understood, since other forms of iron oxide, including red and yellow, do not appear to cause the same long term problem, unless some black iron oxide is either present as an impurity, or is deliberately included to achieve a desired colour effect.
It may be that the chemical/physical structure of black iron oxide, in which iron is present predominantly in the trivalent ferric form Fe304, as opposed to the predominantly ferrous Fe203 found in other widely used pigments comprised of iron oxide, serves to catalyse in some hitherto unappreciated way the progressive breakdown of acrylic resin when subjected to ultra violet light and water. It should be noted that so-called "brown" iron oxide pigments normally contain some black iron oxide. The latter is commonly added to develop a desired colour shade, or it may be present as an impurity.
It will therefore be understood that whilst "black iron oxide" is used throughout this specification to mean black iron oxide predominantly comprised of ferric iron oxide, the term "black iron oxide" also includes brown iron oxide in which such black iron oxide is present . Indeed black iron oxide is used even in some white and relatively light coloured coating compositions in order to achieve specific colour finishes. This may explain why even white and light coloured surface coatings are unexpectedly vulnerable to extreme long-term weathering.
It has been found that by re-formulating a known, iron oxide-containing aqueous acrylic resin composition to exclude black iron oxide, coatings made by applying the resultant composition exhibit exceptional resistance to prolonged exposure to ultra violet light and water, without significant cost or formulation complexity implications.
To illustrate this, commercial board samples coated during manufacture with conventional acrylic resin compositions containing black iron oxide pigment to develop black and simulated dark slate finishes were subjected to an industry standard "QUV" long-term test.
This test is based on exposure to ultra violet light ("B" type UV light) for eight hours, followed by exposure to water for eight hours. This alternating exposure cycle was repeated for 5000 hours. The board samples were then inspected. The exposed part of the surface was now grey rather than black and the initial slight gloss had become completely matt. To all intents and purposes, the resin component of the coating had been considerably damaged by the test conditions.
Fresh board samples were then prepared using exactly the same resin coating composition, but with one vital difference. In the manufacturing process there was included the step of formulating the coating composition to contain iron oxide essentially free from black iron oxide. Replacement pigments based on copper, chromium and/or manganese were included to give the same colour finish as before. The QUV tests were repeated and the samples compared with the ones resulting from the original tests. Surprisingly, the second set of samples exhibited virtually none of the surface changes previously noted. The initial gloss was well retained and there was no significant colour change. This was an exceptional and hitherto unexpected result.
As previously stated, the invention is applicable to the manufacture of aqueous acrylic resin coating compositions useful for surface coating throughout the fibre-cement board industry. It is also applicable to the production of surface coatings for masonry, especially to exposed concrete surfaces where lime efflorescence is a well- known problem.
To further illustrate the invention a preferred embodiment of it will now be described with the aid of the following Examples, in which Example I is taken from the prior art.
EXAMPLE I. A typical prior art coating composition for fibre cement sheet was compounded from:
Ingredient % by weight
Water 26.5
Surfactant 0.5
Antifoaming agent 0.4
Thickener 0.1
Black iron oxide 6.7
Titanium dioxide 2.8
Yellow iron oxide 0.5
Inert filler 1.5
Aqueous acrylic binder 60.0
Coalescent solvent 1.0
Example II. A coating composition was then compounded according to the present invention using similar ingredients, except for the step of formulating the composition to be essentially free from black iron oxide.
Ingredient % by weight
Water 26.5
Surfactant 0.5
Antifoaming agent 0.4
Thickener 0.1 Mixed metal oxide pigment (essentially free from black iron oxide) 6.8
Titanium dioxide 1.8
Yellow iron oxide 0.8
Red iron oxide 0.6
Inert filler 1.5 Aqueous acrylic binder 60.0
Coalescent solvent 1.0
These two compositions were thus directly comparable, with the one major exception, namely that black iron oxide was replaced in the second formulation by a mixture of oxides free from black iron oxide, in accordance with the present invention.
Both compositions were applied to fibre-cement profiled sheet by a conventional continuous flow coating process in which the coating was dried/cured by passage through a drying oven. The finished sheet product was in each case a typical grey colour. Samples of the finished sheets were then subjected to a 5000-hour industry standard QUV test involving alternating eight-hour exposures to B-type UV radiation and water respectively. The samples from the sheet coated with the composition of Example II, and according to the present invention, were virtually unaffected by the test, but the samples coated with the prior art composition were significantly degraded, exhibiting a marked matt appearance and a colour change to the original grey. The integrity of the coating was found on microscopic investigation to have been severely compromised, exposing the fibre cement material underneath.
The invention further includes the use of a composition made by the method of the invention to provide a durable surface coating for fibre cement sheet. It further includes fibre cement sheet treated with a composition according to this invention.
