VI. DETAILED DESCRIPTION

[0042] As illustrated in FIG. 1, anticorrosive properties can be obtained by adding sacrificial metal particles (104) into a coating matrix (102). The sacrificial metal particles can be electrically connected with the substrate (101) it is protecting. Accordingly, three possible electrical conduction pathways can be created and are described as follows: A) between CNTs (105) only; B) between the zinc particles (104) and the CNTs (105); or C) between the zinc particles (104) only. According to measurements shown in Examples 1-3, the mixed case B, provides the best conductivity and is the least sensitive to disturbances due to large, non-conductive aggregates (103) that provide non-skid properties.

[0043] The present teaching relates to non-skid coating compositions capable of providing cathodic protection. Because the present teaching does not require an anticorrosive primer, such as a zinc-rich primer, or a weatherable topcoat, a one-coat solution is presented here. Typical formulations that are in accordance with the present teaching are comprised of curable resins, modifiers, curing agents, sacrificial metal particles, carbonaceous material, aggregates, fillers, pigments, and solvents. Specific examples are provided in Table 4 below, but it should be apparent to one skilled in the art that a range of each component can be used to afford a system with useful properties. As such, any composition containing, by weight, of approximately 5 to approximately 20% curable resins, approximately 0 to approximately 7.5% modifiers, approximately 25 to approximately 65% sacrificial metal particles, approximately 10 to approximately 40% aggregates, approximately 0.001 to approximately 5.0% carbonaceous material, approximately 0 to approximately 20% solvent, approximately 0 to approximately 10% pigments, approximately 3 to approximately 18% fillers, and approximately 3 to approximately 15% of curing agents would encompass the general scope of the present teaching.

The sacrificial metal particles should have an average diameter ranging between about 0.01 to about 100 microns.

[0050] Inorganic and organic corrosion inhibitors can be added to the composition to supplement the corrosion resistance of the coating. Suitable corrosion inhibitors that are in accordance with the present teaching are anodic inhibitors, cathodic inhibitors, mixed inhibitors, and volatile corrosion inhibitors. These inhibitors may be used alone or in combination with one another. Suitable examples may include, but are not limited to, N-nitrosamines, mercaptobenzothiazoles, zinc phosphates, calcium phosphates, zinc aluminum orthophosphates, strontium aluminum polyphosphates, and zinc molybdenum orthophosphates.

[0051] The compositions of the present teaching are principally designed for metal substrates although they can be used on any substrate where protection of said substrate and non-skid properties are desired. The metal substrates of interest can consist of different types of steel such as, but not limited to, carbon steel, stainless steel, and steel alloys as well as aluminum and aluminum alloys.

[0052] Carbonaceous material increases the electrical conductivity and the mechanical properties of the composition. Carbonaceous material that is in accordance with the present teaching includes carbon nanotubes, graphene, graphite, fullerene, amorphous carbon black, and mixtures thereof.

[0053] Organic solvents or water can be used to adjust the viscosity, pot-life, and workability of the composition. Suitable solvents may be selected from xylenes, aromatic hydrocarbon mixtures such as solvent 100, alcohols such as butanol, glycol ethers such as propylene glycol monomethyl ether, glycol ether esters such as propylene glycol monomethyl ether acetate, aliphatic hydrocarbons such as n-hexane, esters such as tert-butyl acetate, ketones such as methyl ethyl ketone, and water. These solvents may be used alone or in combination with one another to achieve good film formation.

These coupling agents are useful for improving the cohesive strength of the composition.

[0058] One method of preparing curable compositions includes mixing component A, which contains the curable resin, with component B, which contains the curing agent. The aggregate may be incorporated into component A or into component B. Alternatively, the aggregate can be added separately as a third component, component C. In one aspect of the present teaching, component C is added to the mixture of component A and component B. This mixture of all three components is then applied to a substrate to create the non-skid coating. In another aspect of the present teaching, the mixture of component A and component B is applied to a substrate.

[0059] Component C is then added over the top of the mixture of component A and component B to create the non-skid coating.

EXAMPLES

[0060] Preliminary electrical resistance measurements were conducted to find alternative means of lowering the electrical resistance of conventional zinc-rich coatings. It was found that higher loading levels of zinc dust led to lower electrical resistance. However, the addition of CNTs, zinc flakes, and/or graphene dramatically decreased the resistance values at a constant zinc dust loading level (see Tables 1-3). Therefore, zinc flakes and carbonaceous material were beneficial to obtaining the desired percolation threshold in a complicated system filled with non-conductive components.

Example 4

[0064] Preparation of the non-skid coating compositions.

[0065] Typical formulations that are in accordance with the present teaching are provided in Table 4 below. The amount of each raw material is displayed as a weight percentage.

[0066] Component A was prepared by adding the resin, modifier, thixotropes, and carbonaceous material dispersion into a kettle that was equipped with an air-driven mixer. The mixing shaft was fitted with a Cowels blade and the mixture was homogenized. The titanium dioxide, zinc particles, and filler were subsequently added. The dry ingredients were added slowly to ensure that adequate mixing was achieved. Solvent from the let-down was added as needed to maintain adequate mixing. The mixture was heated to 65° C. with high shear mixing and was continued until a homogeneous consistency was obtained. Thereafter, the remaining let-down solvent was added and the batch was cooled.

[0067] Component B was prepared by adding the curing agent, solvents, and catalyst to a kettle equipped with an air-driven mixer. The mixing shaft was fitted with a propeller blade and the contents were mixed at low speed until completely homogeneous.

[0068] Similar procedures were used to prepare component A and component B for each of the subsequent formulations. Although specific amounts of each raw material are mentioned in the examples provided, it should be apparent to a person skilled in the art that a compositional range can be used to achieve non-skid coatings with useful properties.

[0069] The non-skid coating is made by stirring components A, B, and C together until homogeneous. Once the components are mixed together, the coating can be applied to a substrate with a roller, trowel, squeegee, or by spray application. The aggregates, which are denoted as component C, may be added as a separate, third component, as is presented in Table 4 below. However, the aggregates may also be incorporated into component A or component B ahead of time, during the preparation of component A and component B. As such, the non-skid coating may exist as either a 2-component or 3-component system.

[0070] Alternatively, the non-skid coating can be made by stirring components A and B until homogenous and then applying said mixture to a substrate. This can be accomplished with a roller, trowel, squeegee, or by spray application. The aggregates can then be applied over the top of the wet coating, via a process known as broadcasting, to create the non-skid coating.
