The present invention relates to materials and products for repair of abrasion-resistant, non-decorative tile, brick or plate for bulk materials handling, military applications and aerospace applications.
Non-decorative industrial grade tile has been in use for many years. Installed tile at times needs to be repaired due to wear (or abrasion) on the tile. Materials used for such repairs can be referred to as “wear components” or “wear material.”
A significant drawback of current industrial ceramic wear components is the permanent rigidness of the components. This rigidness prevents the wear material from being shaped to fit into custom applications. Cutting and/or breaking the ceramic wear components to fit to size on custom applications comes at a great inconvenience and expense, while greatly reducing overall quality and performance. When faced with countless problems while doing industrial repairs and/or installing Industrial Ceramic Abrasion Resistant components, such as filling gaps and shaping and molding custom parts on the spot. Using conventional methods requires countless hours of cure time and breaking or cutting ceramic parts with great expense and inconvenience.
In a preferred embodiment, the present invention is UV cured cross-linked liquid resin reinforced with, e.g., impregnated with, ceramic inorganic nanoparticles and ceramic inorganic abrasion-resistant powder. The UV cured resin achieves at least ⅛″ of fully cured material within 5 minutes when exposed to appropriate UV light. The UV-cured cross-linked liquid resin reinforced with ceramic inorganic nano-particles and ceramic inorganic abrasion-resistant powder is comprised of 30%-45% by weight resin, wherein the resin is at least one of 2-propenoic acid, homopolymer, isophthalic acid, 1,4-Dimethoxybenzene, saturated polyester resin, and maleic anhydride; 10%-20% by weight industrial ceramic inorganic nano-materials; 30%-45% by weight industrial ceramic inorganic abrasion-resistant powder; and styrene, wherein the styrene is less than 25% by weight of the UV-cured cross-linked liquid resin reinforced with ceramic inorganic nano-particles and ceramic inorganic abrasion-resistant powder.
The UV-cured cross-linked liquid resin reinforced with ceramic inorganic nanoparticles and ceramic inorganic abrasion-resistant powder may be comprised of 45% resin by weight. The industrial ceramic inorganic nanomaterials may comprise aluminum hydroxide. The industrial ceramic inorganic abrasion-resistant powder comprises at least one of silicon dioxide, amorphous, fumed silica and/or silica glass. The industrial ceramic inorganic nanomaterials and the industrial ceramic inorganic abrasion-resistant powder together may make up 50-60% of the UV-cured cross-linked liquid resin reinforced with ceramic inorganic nanoparticles and ceramic inorganic abrasion-resistant powder by weight. The industrial ceramic inorganic nanomaterials and the industrial ceramic inorganic abrasion-resistant powder together make up 55% of the UV-cured cross-linked liquid resin reinforced with ceramic inorganic nanoparticles and ceramic inorganic abrasion-resistant powder by weight.
In another preferred embodiment, the present invention is a method for repairing an industrial material. The method comprises preparing a surface of an industrial material such as by cleaning the surface, filling gaps in the prepared surface of the industrial material with a UV-cured cross-linked liquid resin reinforced with ceramic inorganic nano-particles and ceramic inorganic abrasion-resistant powder, and applying ultra-violet light to the UV-cured cross-linked liquid resin reinforced with ceramic inorganic nano-particles and ceramic inorganic abrasion-resistant powder. The UV-cured cross-linked liquid resin reinforced with ceramic inorganic nano-particles and ceramic inorganic abrasion-resistant powder comprises 30%-45% by weight resin, wherein the resin is at least one of 2-propenoic acid, homopolymer, isophthalic acid, 1,4-Dimethoxybenzene, saturated polyester resin, and maleic anhydride; 10%-20% by weight industrial ceramic inorganic nano-materials; 30%-45% by weight industrial ceramic inorganic abrasion-resistant powder; and styrene, wherein the styrene is less than 25% by weight of the UV-cured cross-linked liquid resin reinforced with ceramic inorganic nano-particles and ceramic inorganic abrasion-resistant powder.
The industrial material may comprise abrasion-resistant industrial ceramic tile.
In yet another embodiment, the present invention is a system for repairing an industrial material. The system comprises an applicator and a UV-cured cross-linked liquid resin reinforced with ceramic inorganic nanoparticles and ceramic inorganic abrasion-resistant powder. The UV-cured cross-linked liquid resin reinforced with ceramic inorganic nanoparticles and ceramic inorganic abrasion-resistant powder comprises 30%-45% by weight resin, wherein the resin is at least one of 2-propenoic acid, homopolymer, isophthalic acid, 1,4-Dimethoxybenzene, saturated polyester resin, and maleic anhydride; 10%-20% by weight industrial ceramic inorganic nanomaterials; 30%-45% by weight industrial ceramic inorganic abrasion-resistant powder; and styrene, wherein the styrene is less than 25% by weight of the UV-cured cross-linked liquid resin reinforced with ceramic inorganic nano-particles and ceramic inorganic abrasion-resistant powder.
Still other aspects, features, and advantages of the present invention are readily apparent from the following detailed description, simply by illustrating a preferable embodiments and implementations. The present invention is also capable of other and different embodiments and its several details can be modified in various obvious respects, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature, and not as restrictive. Additional objects and advantages of the invention will be set forth in part in the description which follows and in part will be obvious from the description or may be learned by practice of the invention.
For a more complete understanding of the present invention and the advantages thereof, reference is now made to the following description and the accompanying drawings, in which:
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.
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:
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.
As shown in
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.”
The UV cured resin of the present invention may have many other applications, such as to encapsulate a bolt as shown in
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.
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.
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.
