Title

DECORATIVE PAINT COATING WITH FABRIC EFFECT

Description

[0001] The present invention refers to a textile-effect painted decorative coating.

More particularly, the present invention refers to an aqueous phase paint system, the process for production of the paint system and the method of application of said decorative coating. [0002] The coating of the present invention behaves like a decorative element due to the aspect it gives the painted wall. [0003] The coating of the present invention creates a particular aesthetic effect on the painted surface, giving it an irregular, veiled look. A wall covered with the coating of the present invention takes on an appearance similar to that of a wall covered with wallpaper which reproduces the weave of a fabric, in particular cotton twist or denim. [0004] The final aspect of the painted surface is such that it can be considered a decoration for enhancing the appearance of internal walls. [0005] The subject of the present invention is therefore a paint system comprising the following aqueous products: [0006] (A) a paint product (A) comprising (parts by weight, p/w):

- 92 to 98 p/w of an aqueous product (1), and

- 2 to 8 p/w of a pigmented toner;

[0007] (B) a paint product (B) comprising (parts by weight):

- 3 to 9 p/w of the aqueous product (A) and

- 91 to 97 p/w of an aqueous product (2) comprising a pigment, [0008] in which the product (1) when dry comprises:

- 10 to 45 p/w of a silicon monoxide in granule form, the granulometry of said granules varying from 20 μm to 130 μm, preferably from 35 μm to 110 μm, and

- 2 to 15 p/w of a silicate of aluminium, sodium and potassium, preferably in hydrated form, the silicate being in the form of granules with dimensions varying from 5 μm to 450 μm, preferably from 10 μm to 350 μm.

[0009] In the present description the term "dry product" means that the product does not contain added water, therefore the quantities in parts by weight refer to the weight of the components excluding the added water. The quantities of the components indicated below for the products (1) and (2) all refer to the dry products, unless explicitly indicated otherwise.

[0010] More specifically the product (1) comprises the silicon monoxide in granule form. The granulometry of said granules varies typically from 20 μm to 130 μm, preferably from 35 μm to 110 μm. Typically, but without limitation, 65 to 90% of said granules have a granulometry of approximately 40 μm and 10 to 30% have a granulometry of approximately 100 μm. Said monoxide acts as a filler.

[0011] The product (1) comprises, furthermore, the silicate of aluminium, sodium and potassium, preferably in hydrated form. Typically the silicate is in granule form with dimensions varying from 5 μm to 450 μm, preferably from 10 μm to 350 μm. Typically, but without limitation, 10 to 50% of said granules have a granulometry from 10 to 70 μm and from 50 to 90% have a granulometry from 70 to 150 μm.

[0012] The pigmenting toner to be added to the product (1) comprises at least one organic or inorganic pigment, chosen from those commonly used in said sector. Mineral pigments, such as iron, chromium and tin oxides, and organic pigments, such as copper phthalocyanine blue and green, are only representative examples of pigments taken from those most widely used.

[0013] The product (1), which is an aqueous product, also comprises approximately 10 to 30% in weight of water in addition to the above- mentioned components.

[0014] The product (B) comprises (parts by weight):

- 5 to 9 p/w of product (A), and

- 91 to 95 p/w of an aqueous product (2).

[0015] The product (2) comprises an inorganic pigment which is, preferably, titanium dioxide. Said oxide has a granulometry typically from 1 to 3 μm. Said inorganic pigment is preferably from 0.40 to 5, preferably from 0.45 to 5 p/w with respect to the overall weight of the product (2).

[0016] In the products (1) and (2), in addition to the above-mentioned components, there are also other compounds which are usually present in paint products and therefore well known to a person skilled in the paint field. [0017] Examples of compounds usually present in the compositions of paint products and which are preferably included in the products (1) and (2) are structuring additives, retarding agents, preserving agents, deaerating agents, binding agents and dispersing agents.

[0018] The structuring additive can be chosen, for example, from sodium hydroxyethylcellulose, acrylic polymers in aqueous dispersion or in anionic aqueous emulsion, polymethacrylic acid in aqueous dispersion with low viscosity, polyurethane solutions in an aqueous mixture. The preferred additives are sodium hydroxyethylcellulose and the acrylic polymer in an anionic aqueous emulsion. When present in the product (1), said agents are roughly in a quantity that varies from 0.050 to 0.30 p/w. When present in the product (2), said agents are roughly in a quantity that varies from 0.20 to 2.50 p/w.

[0019] The preserving agents with bactericidal function comprise, preferably, the derivatives of isothiazolinone, such as chloromethylisothiazolinone and chromomethyl-methylisothiazolinone. When present in the product (1), said agents are roughly in a quantity that varies from 0.070 to 0.50 p/w. When present in the product (2), said agents are roughly in a quantity that varies from 0.040 to 0.30 p/w.

[0020] The deaerating agents are, for example, the polysiloxanes and paraffin waxes in alkylated hydrocarbons. When present in the product (1), said agents are roughly in a quantity that varies from 0.050 to 0.50 p/w. When present in the product (2), said agents are roughly in a quantity that varies from 0.040 to 0.50 p/w.

[0021] The binding agents for water-based paints are, for example, acrylic acid and its derivatives, for example methacrylic acid and the polymers of said acids, in suspension or emulsion; if said polymers are copolymers, they are obtained by polymerising the following monomers: acrylic acid, methacrylic acid, styrene. When present in the product (1), said agents are roughly in a quantity that varies from 5.0 to 25.0 p/w. When present in the product (2), said agents are roughly in a quantity that varies from 11.0 to 35.0 p/w. [0022] Suitable retarding agents are, for example, the non-ionic surface-active agents, such as the long-chain alcohols (or fatty alcohols) and monoethylenic propylene glycol. When present in the product (1), said agents are roughly in a quantity that varies from 0.30 to 2.0 p/w. When present in the product (2), said agents are roughly in a quantity that varies from 1.50 to 10.0 p/w.

[0023] The dispersing agents are, for example, chosen from among the ammonium salts of a carboxylic acid, also in polymeric form such as the polyacrylates, linear acrylic polymers, aminomethyl propanol, sodic salts of polycarboxylic acids and their mixtures. Their function is that of preventing the formation of scale and, at the same time, improving the applicability of the paint systems since they act as fluidifiers of the mixture. When present in the product (1), said agents are roughly in a quantity that varies from 0.10 to 2.0 p/w. When present in the product (2), said agents are roughly in a quantity that varies from 0.040 to 0.30 p/w.

[0024] In addition to the above-mentioned compounds, the product (1) also contains other compounds, which may be present in paints, such as opacifying fillers, ion sequestering agents, anti-foaming agents, distending agents, pH stabilising agents and rheological additives.

[0025] The opacifying filler is, for example, calcium carbonate, in its various polymorphous forms. Preferably the product (1) comprises both neutral calcite and a mixture of the above-mentioned polymorphous forms (indicated below for the sake of brevity as calcium carbonate). In said case, the product (1) generally comprises both the above-mentioned mixture of the polymorphous forms of the calcium carbonate and the calcite, in ratios of roughly 1.5:0.5 to 0.5:1.5, preferably 1.3:0.7 to 0.7:1.3 respectively. When present in the product (1), said filler is in an overall quantity which roughly varies from 10.0 to 50.0 p/w.

[0026] The ion sequestering agents are, for example, the salts of polyphosphoric acids, in particular sodium polyphosphates; a particular example is sodium hexametaphosphate (also known as Graham's salt). When present in the product (1), said agents are roughly in a quantity that varies from 0.50 to 3.0 p/w. [0027] The anti-foaming agents can be chosen, for example, from mineral oils in combination with polysiloxane-polyethers, polyalcoxy esters or emulsions of silicon compounds, such as amorphous silica, the amorphous silicon polymers, polysiloxane, etc. When present in the product (1), said agents are roughly in a quantity that varies from 0.050 to 0.40 p/w.

[0028] The distending agents have the function of "distending" the film, avoiding an over-evident orange peel effect. An example is monoethylenic 1,2- dihydroxypropane. When present in the product (1), said agents are roughly in a quantity that varies from 2.0 to 8.0 p/w.

[0029] The pH stabilising agents allow an alkaline pH to be maintained. Suitable stabilising agents are, for example, the aminic derivatives, such as aminomethyl propanol and triethanolamine, and sodium hydroxide in aqueous solution. When used in the product (1), said agents are preferably in a quantity of between 0.10 and 2.0 in weight.

[0030] The rheological additives are, for example, the polymers of acrylic acid. Said additives have the function of modifying the fluidity of the paint.

[0031] In addition to the above-mentioned compounds, the product (2) also contains other compounds, which may be present in the paint products, such as an opacifying filler and a coloured filler.

[0032] The opacifying filler is preferably water-repellent, for example a polyolefin wax. When present in the product (2), said filler is roughly in a quantity that varies from 0.90 to 7.0 p/w.

[0033] The coloured filler is, for example, a pigmented polyurethane. When present in the product (2), said filler is roughly in a quantity that varies from 1.50 to 10.0 p/w.

[0034] The product (2), which is an aqueous product, comprises, in addition to the above-mentioned components, also roughly 50 to 70% in weight of water.

[0035] The products (A) and (B) can be used both as they are and, if necessary, in a more diluted form, in said case adding an appropriate quantity of water; roughly, the ratio between product (A) and quantity of water added varies from 1 :0.01 to 1 :0.25 p/w and the ratio between product (B) and quantity of water added varies from 1 :0.5 to 1 :1.5 p/w. [0036] The paint system of the present invention is prepared by producing the paint products (A) and (B) separately, as illustrated below. Once prepared, the paint products (A) and (B) are applied separately and successively on the surface to be painted.

[0037] The products (A) and (B) are prepared by simple mixing in the mixers commonly used in the paint sector; the mixing can be performed under the following conditions (unless explicitly indicated otherwise): ambient temperature up to approximately 70⁰C and speed from approximately 300 to 700 r.p.m. (with a 400 mm impeller).

[0038] The components for each product are indicated below and for each one also the preferred quantities referred to the products (A), (B) and (1) or (2), as the case may be.

[0039] The product (A) is obtained, for example, by a process that consists of at least three phases. The first phase concerns the preparation of five separate mixtures, i.e. mixture (i), mixture (ii), mixture (iii), mixture (iv) and mixture (v), described in detail subsequently. In the second phase said mixtures are mixed with one another, obtaining the product (1). In particular, said second phase of the process consists, in turn, of four successive stages: in the first stage the mixture (ii) is mixed with the mixture (i), while in the second, third and fourth stages, the mixture (iii), mixture (iv) and mixture (v) are added, respectively for each stage, to the mixture obtained in the immediately preceding stage. In the third phase, lastly, the product (1) is mixed with the pigmenting toner.

[0040] In the second phase of said process, mixing of the mixture (iii) with the mixture coming from the first stage of the process is performed, preferably, by slowly agitating the mixture that forms - the agitation speed is approximately 100 to 200 r.p.m. - throughout the adding time and then continuing the mixing for 5-10 minutes.

[0041] The mixtures (i)-(v) are obtained by simple mixing of the components, indicated as parts by weight with respect to the product (1).

- deaerating agent, from 0.050 to 0.50 p/w;

- preserving agent, from 0.020 to 0.20 p/w; and

- water, roughly from 0.46 to 4.7 p/w.

[0047] The product (B) is obtained, for example, by a process consisting of three phases. The first phase concerns the preparation of three separate mixtures, i.e. mixture (A), mixture (B) and mixture (C), described in detail subsequently. In the second phase said mixtures are mixed with one another, obtaining at the end the product (2). In particular, said second phase of the process consists, in turn, of two successive stages: in the first stage the mixture (B) is mixed with the mixture (A), while in the second, the mixture (C) is added to the mixture obtained in the first stage. In the third phase, lastly, the product (2), obtained in the second phase, is mixed with the product (A). [0048] The mixtures (A)-(C) are obtained by simple mixing of the components, indicated as parts by weight with respect to the product (2). [0049] The first mixture, mixture (A), is prepared by mixing:

- structuring agent, from 0.250 to 2.50 p/w;

- white pigment, from 0.50 to 5.0 p/w;

- water-repellent opacifying agent, from 1.0 to 7.0 p/w;

- water, roughly from 0.50 to 4.10 p/w. [0051] The mixture (C) is prepared by mixing:

- coloured filler, from 2.0 to 10 p/w; and

- water, roughly from 1.20 to 6.70 p/w.

[0052] The third phase of the process for preparation of the product (B) consists in mixing the mixture (1), in a quantity from 90.0 to 96.0 p/w, preferably from 92 to 94.5 p/w, with the product (A), in a quantity from 4.0 to 10 p/w, preferably from 5.5 to 8 p/w.

[0053] A further subject of the present invention concerns the method of application of the paint system claimed. Said method consists in the following stages:

1) treat, if necessary, the surface to be painted with a water-based acrylic type primer;

2) apply a coat of paint product (A);

3) leave the product (A) to dry;

4) after a few hours, preferably at least 8-10 hours, from the end of stage (2), apply another layer of product (A);

[0054] The product (A) is applied with flat brush and Spalter type brushes. The total thickness of product (A), referred to both the layers, varies roughly between 100 and 250 μm.
