DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] Instead of attempting costly and potentially dangerous conventional methods, the end user needs a one-component thixotropic paste that can be formed into virtually any shape and cured to extreme strength and hardness within minutes. Essentially, a high strength “industrial ceramic parts factory in a tube” is needed. There is an extreme need in virtually all industries for a molding material where an average citizen can make strong custom parts and/or make quality permanent custom repairs in minutes.

[0019] The present invention is a UV cured cross-linked liquid resin reinforced with ceramic inorganic nanoparticles and ceramic inorganic abrasion-resistant powder comprised of the following in percentages by weight: [0020] 30%-45% resin from any of 2-propenoic acid, homopolymer (CAS Nos. 9003-01-4), Isophthalic acid (CAS No. 121-91-5), 1,4-Dimethoxybenzene (CAS No. 150-78-7, dimethyl 5-sodiosulfoisophthalate-ethylene glycol-isophthalic acid-terephthalic acid copolymer (CAS No. 61926-16-7), or Maleic anhydride (CAS No. 108-31-6); [0021] 10%-20% industrial ceramic inorganic nanomaterials including aluminum hydroxide (CAS No. 21654-51-2); [0022] 30%-45% industrial ceramic inorganic abrasion-resistant powder such as silicon dioxide (CAS No. 14808-60-7), amorphous, fumed silica (CAS No. 112945-52-5) and/or silica glass (CAS No. 60676-86-0); and [0023] styrene (less than 25%) (CAS NO. 100-42-5).

[0024] This composition forms a UV cured industrial paste for repair of wear-resistant (or abrasion-resistant) material and casting custom parts. The UV cured resin must achieve at least ⅛″ of fully cured material in less than 5 minutes when exposed to the appropriate UV Light. When the UV activated resin is fully cured and hardened it must attain a hardness of greater than 60 Barcol using the Barcol impresser scale. The resin preferably comprises about 45% of the nanocomposite by weight. The ceramic inorganic materials and abrasion resistant powder together preferably comprise 50%-60%, and preferably about 55%, of the nanocomposite by weight.

[0025] As shown in FIGS. 1 and 3, in the context of non-decorative industrial tile, the present invention can be used in repairing/replacing tiles. First, the surface is prepared for application of replacement tiles, for example, by removing broken tiles and/or cleaning the surface where tiles have been removed or have fallen off (step 110). Next, a replacement tile 310 is applied (step 120). The replacement tile 310, for example, may be a tile such as is disclosed in Published International Patent Application No. WO 2020/005730, entitled “Non-Decorative Industrial Grade Self-Adhesive Tile And Method Of Manufacturing Thereof.” Once the replacement tile 310 is in place, the UV cured industrial paste of the present invention is used to fill/grout the gaps 320 between tiles (step 130). UV light is then applied to the UV cured industrial paste in the gaps to cure the paste (step 140). The UV light is applied for 1-5 minutes, and preferably is applied for 4-5 minutes. An exemplary tile after completion of the application of the UV light is shown in FIG. 3. Ns. The UV cured industrial paste of the present invention may be applied in any appropriate manner. An exemplary application is shown in FIGS. 2A-2D. The paste 220 is placed within a flexible opaque material such as plastic 210. The flexible material 210 is then punctured with a knife, box cutter or the like 250 to create an opening in the flexible material 210. The flexible material is then squeezed to apply the paste to the gaps in the tile.

[0026] The present invention may be used with other types of applicators and is by no means limited to this particular applicator. For example, the US cured industrial paste of the present invention could be placed within a housing or container having a plunger to push the paste out of a nozzle. Such a container could be made of any of many different materials, including but not limited to plastic. Any of these or many other known means for holding the paste and applying it may be referred to as an “applicator.”

[0027] The UV cured resin of the present invention may have many other applications, such as to encapsulate a bolt as shown in FIG. 4.

[0028] The materials and products according to the present invention may be used, for example, for repair of abrasion-resistant, non-decorative tile, brick or plate for bulk materials handling, military applications and aerospace applications including, but not limited to, General Aerospace Repair, Aerospace Composite Repair, Carbon Fiber Repair, Automotive Composite Repair and other Advanced Composite Repair.

[0029] A significant drawback during Aerospace repair and other advanced composite repair are the lengthy cure times coupled with labor intensive multipart resin components. Mandatory cold storage of resins and the specialized heat equipment required for high temperature induced curing methods leads to costly and extremely time-consuming repairs.

[0030] The Aerospace Industry and advanced composite repair industry are in great need of a One-Part UV cured Nano-Composite that can literally achieve full cure of at least ⅛″ in less than 5 minutes. The nanocomposite of the present invention can be stored at room temperature and maintain its stability and viability for 2, 3, or even 5 or more years.

[0031] The one-part nano-composite of the present invention can also reinforce or be reinforced with a multitude of various fillers, fibers and/or composites including, but not limited to: Chopped Carbon Fiber, Continuous Carbon Fiber, Kevlar, Dyneema, Woven Reinforcements, Multiaxial Reinforcements, Honeycomb, Ceramic Fibers, Aluminum Fibers, Quartz Fabric, Man Made Vitreous Fiber, Glass Fiber Mats, Glass Fiber chopped strand mats, Polyamide Fabrics, Fiber Reinforcements (Fibers, whiskers, particles), Rigid Foam, Wood, Metal, Paper Honeycomb, Nomex Honeycomb, Carbon Honeycomb, Fiberglass Honeycomb, Metal Honeycomb, Fiberglass Cloth, Nylon, Cotton, Nylon Thermoplastic Fibers, Polyester Thermoplastic Fibers, E-Glass, E-CR Glass, S-Glass, Alumina-Lime-Borosilicate, Aramid Fibers (Polyaramids), CARBON FIBERS, Graphite Fibers (>99% Carbon Fibers), Spider Silk (Natural), Spider Silk (Man-Made) Aromatic Polyamid, Man-Made Organic Fibers, Aluminum Oxide nano-particles, Aluminum Hydroxide nano-particles, Graphene, Halloysite, Wollastonite, Talc, Mica, Glass Beads, Hollow glass, Roving Mat, Milled Fiber Mat, Chopped Strand Mat, Continuous Fiber May, Thermoform-able Mat, Multi-End Rovings, Single-End Rovings Filament winding applications, Pultrusion applications, Non-Woven Veils, Soluble & Insoluble Fibers, Unidirectional reinforcements, Tapes, Tows, unidirectional tow sheet and roving, Monocrystalline Whiskers, Polymer-Matrix-Composites, Metal-Matrix-Composites, Ceramic-Matrix-Composites, Silicon Carbide, Carbon Nano Tubes, Titanium Dioxide, Titanium Carbide, Unidirectional Tapes, Non-Crimp Fabrics, Dry Carbon Fabrics, Yarns, Petroleum Pitch, Polyacrylonitrile, Rayon, phenolic micro-balloons, plastic micro-balloons, Reactive Carbon Nano-Fibers, Nano-Cellulose, and Cellulose Nano-Crystal.
