Description
SPECIFICATION
Curable pigmented silicate compositions
This invention relates to curable pigmented silicate compositions.
During the past several years, environmental pollution concerns have led those active in the coatings, castings and moldings arts to develop various curable compositions in which organic solvents derived from petroleum have been eliminated or at least substantially minimized. Thus, compositions such as water-based compositions and high solids compositions have been extensively investigated.
Even more recently the high cost and scarcity of petroleum by-products has engendered interest in the development of curable compositions which are composed entirely of, or at least substantially of, inorganic components.
Inorganic coating compositions based on alkali metal silicates are well known in the art. Such compositions can be applied from an aqueous medium alone or in combination with various known insolubilizing agents. The insolubilizing agents aid in the fast formation of a water-resistant silicate coating. The coatings are inorganic in nature with the consequent advantages discussed above and possess a desired set of properties.
Unfortunately, pigmented coatings based on the alkali metal silicate can have a less than desired appearance due to an inadequate pigment dispersion in the coating composition. This inadequate pigment dispersion is most noticeable in lapped areas, where fresh additional coating composition is applied over a first coat of the same composition.
The present invention relates to pigmented inorganic coating compositions based on watersoluble or water-dispersible silicates which are capable of providing coatings having good color uniformity.
As used herein, all percents and ratios are by weight unless otherwise indicated.
According to the present invention, curable aqueous compositions consist essentially of inorganic constituents. More particularly, the curable compositions consist essentially of aqueous solutions or dispersions of silicate glass, pigments and a base having a basicity greater than that of the silicate glass.
In one embodiment of the invention, the base is initially ground with the pigment and the resultant grind then combined with the si'icate glass. This technique of mixing minimizes shock. In a preferred embodiment, the compositions additionally consist essentially of a water-soluble metal ion containing latent insolubilizing agent. It has been found that the base-containing compositions of the invention have a pigment dispersion superior to similar compositions not containing the base.
This invention is concerned with the discovery that the presence of certain bases either preadsorbed on a pigment's surface or separately added to compositions containing the pigment and an alkali metal silicate glass, improve the appearance of cured films formed from the compositions. In a preferred embodiment the compositions also contain metal ion containing latent insolubilizing agents.
The compositions consist essentially of an aqueous phase and pigment. Each of the components of the compositions and the compositions' method of production are described in the paragraphs which follow.
Water-soluble or water-dispersible silicates which are employed in the compositions are the alkali metal silicates, e.g., sodium silicate, potassium silicate, lithium silicate, and mixtures thereof. Preferred water-soluble silicate glasses are sodium and potassium silicate with SiO2 : M2O mole ratios of about 2 :1 to about 4:1, with M representing alkali metal. The level of silicate glass in the aqueous phase of the compositions ranges from about 2 percent to about 50 percent, preferably about 10 percent to about 40 percent. (While silicates commerically available are usually aqueous solutions of silicates, the aforementioned percents are given on a silicate solids basis.)
The compositions of the invention also consist essentially of at least one pigment.Preferred pigments are characterized by their ability to adsorb a base from an aqueous solution thereof. Many pigments displaying this characteristic are useful in the compositions of this invention. While the term "adsorb" is employed, it is employed in the sense of removal from solution and is not intended to imply a physical rather than chemical interaction between pigment surface and the base. In fact, the precise mode of interaction is not known. It is believed that any pigment having metal ions on its surface capable of interacting with the base can be enhanced by this invention. This includes most commonly employed pigments.
While the invention enhances the color uniformity properties of any pigment, particularly useful pigments include titanium dioxide, barium metaborate, alumina, zinc oxide, clay and mica. The invention is particularly useful where the compositions contain one or more organic or inorganic coloring pigments which impart a color (other than white), particularly a pastel, bright or intense color. Useful coloring pigments include iron oxide red, barium yellow, zinc yellow, zinc green, cadmium yellow, chrome oxide green, cobalt blue, green or violet, various mixed metal oxides and organic pigments of the azo series. Base-treated pigments are also useful and can, in part or in full, provide the source of the base discussed below. The pigments are employed as dispersed pulverulent solids. Mixtures of pigments can and generally are employed.The pigments are present in an amount of about 5 percent to about 90 percent and preferably about 30 percent to about 70 percent based on the total volume of solids in the composition, i.e., % PVC.
Another essential component of the compositions of the invention is a base having a basicity
greater than that of the silicate glass. Such bases include the alkali metal and quaternary ammonium
hydroxides, e.g., potassium hydroxide, sodium hydroxide and tetraethyl ammonium hydroxide; alkali
metal silicates having a SiO2:M2O mole ratio of from about 1:2 to about 2:1 where M is alkali metal, e.g., sodium orthosilicate; organo silanolates, e.g., tripotassium -aminopropylsilantriolate, tripotassium
N- (-aminoethyl)- -aminopropylsilantriolate, tripotassium -aminopropylsilantriolate, dipotassium -aminopropylmethylsilantriolate, potassium -aminobutyldimethylsilantriolate, tripotassium methylsilantriolate, dipotassium dimethylsilandiolate and potassium trimethylsilanolate; and mixtures thereof.
The base employed has a basicity greater than that of the silicate glass as measured by their respective pH's at the same normality. This results in the compositions having a better dispersion as evidenced by better color uniformity, hiding power, lower viscosity and consistency, and beirig substantially lump-free. The level of base in the aqueous phase of the compositions ranges from about 0.01 percent to about 5 percent. A preferred range of base for dilute applications such as found in electrode deposition coating is from about 0.01 percent to about 4 percent. A preferred range of base in the compositions for other coating applications ranges from about 0.1 percent to about 4 percent. An increase in pH in the vicinity of the surface of the pigment is theorized as being responsible for the compositions' better pigment dispersions.This increase in pH is believed to be due to the base having a greater affinity for the pigment's surface than the silicate glass.
Bases above described can be added directly as a component of the curable compositions during or after their formulation. Alternatively, the base can be admixed with at least a portion of the pigment to be employed in the composition. This latter method of incorporating the base into the compositions is preferred; it has been found the resultant compositions are even more substantially lump-free due to less shock when the pigment/base and silicate are combined to form the coating compositions.
The compositions are water based. While the amount of water can vary widely depending on intended use, generally the aqueous phase of the compositions consists essentially of between about 50 percent and about 98 percent water, preferably between about 60 percent and about 90 percent.
A preferred embodiment of the invention are the above described compositions additionally consisting essentially of a water-soluble latent insolubilizing agent. Such agents improve the waterresistance of the silicate coatings and are for this reason desired. Satisfactory insolubilizing agents are described in the following paragraphs.
Metallate insolubilizing agents are described in U.S. Patent No. 4,140,535, issued February 20, 1979 and copending application Serial No. 868,567, filed January 10, 1978, which are hereby incorporated by reference in their entireties. The described systems comprise a blend of silicates and water-soluble metallate latent insolubilizing agents where the water-soluble latent insolubilizing agent is selected from alkali metal or quaternary ammonium zincates and borates. Still another water-soluble latent insolubilizing agent is an alkali metal or quaternary ammonium aluminate.Illustrative of such metallate latent insolubilizing agents which can be employed are lithium zincate, potassium zincate, and sodium zincate; lithium borate, potassium metaborate, and sodium tetraborate; and lithium aluminate, potassium aluminate, and sodium aluminate. The term "borate" as used in connection with the alkali metal borates is intended to include orthoborates, pyroborates, metaborates and more complex borate ions. The alkali metal aluminates, especially sodium aluminate, are preferred insolubilizing agents.
U.S. Patent 3,715,244, to Campbell, which is hereby incorporated by reference in its entirety, discloses solutions and/or colloidPI suspensions of water-soluble silicates containing monovalent and divalent metal ion complexes. The disclosed metal ion complexes are useful latent insolubilizing agents here also.
Yet other insolubilizing agents are described in U.S. Patent 4,137,087, issued January 30, 1 979 which is incorporated by reference in its entirety. Water-soluble latent insolubilizing agents are formed from metal ions selected from the group consisting of Awl+++, Fe+++, Cr+++ and Sn++ and ligands (i.e., complexing agents) selected from the group consisting of ethylenediaminetetraacetate, diethylenetriaminepentaacetate, N-(hydroxyethyl)ethylenediaminetetraacetate, nitrilotriacetate and 1,3propanediaminetetraacetate. It should be noted that other similar or analogous type ligands where they exist may be employed and these are considered to be within the scope of the invention.Illustrative examples of such latent insolubilizing agents are compounds such as sodium ethylenediaminetetraacetatoaluminate (III), sodium ethylenediaminetetraacetatoferrate (III), sodium ethylenediaminetetraacetatochromate (III), and sodium ethylenediaminetetraacetatostannate (II).
The amount of latent insclubilizing agent included in the compositions can vary considerably depending upon desired properties. However, in general, the amount of latent insolubilizing agent employed is an amount sufficient to enhance wet abrasion and water resistance of the cured composition but which is insufficient to cause an irreversible gel when the uncured composition is stored for 24 hours at 700C. In most instances, amounts of metallate latent insolubilizing agent ranging from about 0.1 percent to about 6 percent, preferably from about 0.25 percent to about 2.5 percent by weight, based upon the combined weight of the silicate glass and metallate latent insolubilizing agent are employed. Insolubilizing agents based on the metal ions and ligands are present at a level of from about 0.2 percent to about 1 2 percent, preferably from about 1 percent to about 5 percent, again based on the combined weight of silicate glass and insolubilizing agent.
The reaction between the silicate glass and latent insolubilizing agent is not known with certitude; however, it is theorized the metallic ion associates with the ligand and the resulting complex maintains the composition in a reasonably stable configuration. However, upon drying (e.g., air drying or baking) the equilibria shift and the metal ion or the metallic ion is released to crosslink the silicate glass and form an insoluble silicate composition having excellent properties. Examples of the properties obtained are stain resistance, flame and heat resistance and water resistance.
The pigmented curable compositions of the invention can contain certain other additives such as, for example, dyes fillers, antioxidants, flow control agents, and surfactants.
In addition it is often advantageous to include in the compositions a thickener. Of particular value are water-soluble thickeners which are solubilized through carboxyl groups. Illustrative of such materials are sodium polyacrylate, potassium polymethacrylate, sodium salts of styrene maleic anhydride copolymers, sodium carboxymethyl cellulose, and potassium polyacrylate copolymers. Also suitable are inorganic thickeners such as clays and the like.
As mentioned above, the curable compositions of the invention can be employed in various applications. The compositions are particularly useful in coatings over a variety of substrates such as wood, metals, glass, wallboard and the like.
The curable compositions can be applied by any conventional method, including brushing, dipping,
rolling, flow coating, roll coating, spraying and the like. Conventional spray techniques and equipment
can be utilized.
The curable compositions of the invention can be cured by baking at moderate or elevated
temperatures if desired. However, one advantageous property of these curable compositions is that they
can be cured by drying in air at ambient temperature without the use of heat. As will be evident,
ambient temperature curable compositions are of considerable advantage in that they provide for
significant energy savings in comparison to compositions which require elevated temperatures for
curing.
The examples which follow are illustrative of the invention with composition B of Example III
representing a preferred embodiment.
EXAMPLE I
A coating composition is formulated in the following manner. Twenty-five (25.0) grams of a
potassium hydroxide solution (40% solids) and 56.4 grams water are mixed together. The resultant
solution is mixed with 62.0 grams of titanium dioxide pigment (Titanox 2060, available from Titanium
International Corp.), 8.0 grams of pigment (Shepherd Green #5, available from Shepherd Chem. Co.)
and 33.0 grams of pigment (barium metaborate, available from Buckman Laboratories as Busan 1 Ml).
Coors beads are added to the mixture, followed by a 1 5 minute grind.
The beads are removed to give a pigment grind having a medium viscosity and little pigment flocculation as evidenced by the presence of only slight "puff" and "hang-up". Puff is defined as being false body, or a high amount of viscosity at low shear rates, that results from pigment fiocculation.
Hang-up results from the puff. Hang-up is evidenced by paint clinging to the side of a container while
paint in the center is being mixed or sheared by the action of the mixer blade. Puff and hang-up are both
undesirable.
Next, 350.0 grams of potassium silicate (mole ratio of SiO2:K2O = 3.9, 29.1% solids) is added to
the pigment grind, followed by 76.0 grams of mica (Micromica C1000, available from English Mica
Corp.), 10.0 grams of clay (Attagel 40, available from Minerals and Chemicals Phillipp Corp.), 4.0 grams
of sodium carboxymethyl cellulose (available from Hercules Chemical Co. as 1 2M8 grade) and 3.0
grams of polyethylene oxide (Polyox WSR-205, available from Union Carbide Corp.). This mixture is
mixed for 1 5 minutes.The final composition is as follows:

Potassium hydroxide (solids) 2.28
Sodium carboxymethyl cellulose 0.92

Shepherd Green #5 4.23
Barium metaborate 17.46
Mica 40.21
Clay 5.29 100.00 The composition has a smooth consistency and no puff or hang-up.
The compositions are next coated onto a prepainted plasterboard substrate and evaluated for pigment dispersibility. This is done by first applying a base coat (application made all in one direction), allowing it to dry and theri applying a second coat (application made in horizontal and vertical directions to the base coat). A visual evaluation of the coated substrate indicates the coating compositions have good color uniformity and good lapping characteristics.

Composition A has noticeable puff, hang-up and the appearance of a gelatinous structure.
Composition B has no puff and a slight, but acceptable, hang-up, while Composition C has no puff and very slight hang-up.
Brush application of the compositions to a plasterboard substrate shows Composition A to exhibit a medium drag during the application. The gelatinous structure of the composition (this being an indication of puff) broke down on repeated brushings. Compositions B and C exhibit only low-medium drag during brush application and the respective paint films show no indication of an objectionable gelatinous structure.

This blend has added to it 49.0 grams water, 62.0 grams titanium dioxide, 8.0 grams Shepherd Green #5 pigment and 33.0 grams barium metaborate and is then ground together with Coors beads for 1 5 minutes. A portion (1 50.0 grams) of the potassium silicate is next added. After removing the Coors beads, a blend of 76.0 grams of micra, 10.0 grams clay, 4.0 grams sodium carboxymethyl cellulose and 3.0 grams of the surfactant is added. The mixture has next added to it the balance of the potassium silicate (200.0 grams) to get the final coating composition. The composition has only slight puff and no hang-up.
Composition B is made in a similar manner with the substitution of potassium hydroxide for the sodium hydroxide.

One composition is made by blending the (a) sodium methylsiliconate with the water, sodium aluminate, potassium hydroxide, glycerine, defoamer, aminomethyl propanol, citric acid and nonionic surfactant with (b) pigments and then combining the blend with the remaining components. No hang-up or puff is observed at any stage of the formulation making; the composition has a smooth consistency at all stages.
A second composition is made identical to the first with the exception being the post addition of the sodium methylsiliconate to a blend of all the other remaining components, followed by agitation.
The final composition has a smooth non-gelatinous consistency, free of puff and hang-up; however, heavy puff and hang-up are noticed in the composition prior to the addition of the siliconate. This illustrates the advantage of adding the base to the pigment prior to combining with silicate.
The above examples illustrate the advantages obtained from the present invention. The examples all show that the inclusion of a base in a silicate-containing composition improves the appearances of resultant coatings.
