Abstract

The invention relates to a method of copper alloy coating articles such as fabric, netting and reinforcement materials comprising glass or carbon fibres for example. A polymeric or poly-epoxide binder 11 binds the copper alloy powder particles 10 to the article or substrate to be coated or to a carrier 12 such as adhesive paper or a rubber bottom surface of a carpet. The coating may be applied to ceramics, steels, aluminium and other metallic substrates. The flexibility permits a wide range of uses. The coating provides an antimicrobial effect. Applications to industrial and consumer products may also include application to face masks, gloves, safety helmets, artificial leather, worktops, toilets, grips, touch surfaces, door parts, ships, brewing equipment, aqua-farming apparatus, trays, phones, electric switches, plugs and buttons and inside baths, pools, air conditioning units, washing machines, water filter apparatus, pipes and tubing, for example. The particles may be 30 to 300 microns in diameter. The article may be rolled after being coated, producing a 3 dimensional structure.

Description

Method and Process to Make Flexible Copper Alloys. Description: The invention relates to Copper/Copper alloy coated Fabric, Netting, and reinforcement materials like Kevlar, glass fibers, Carbon fibers and metals like Steels. Aluminum, and Ceramics.
Flexibility is a key word in describing this invention. Copper itself is an expensive material in today's market, worldwide. In solid sheet form it is too expensive for many governments to use widely, to protect their citizens coming into contact with harmful pathogens. We know that 85% of bacteria and viruses are spread by touch.
Certain surfaces come into greater contact with the general public than others eg, electric switches, door handles, seats, either at home or in the workplace,shopping areas or travelling, poles,handrails and grips on buses and trains. These surfaces are not easily covered with sheet copper and in many instances require replacement ie. "new build"...hence the prohibitive expense.
This invention is flexible and can be applied to existing surfaces, therefore not incurring replacement costs. Its flexibility also allows it to be applied to most substrates using the minimum of microns, again reducing costs in the fight against harmful pathogens. We know the efficacy of copper is its surface not its solidity or its density.
The economic argument for this invention is incalculable.
At the time of writing the price of a copper/ brass electric wall switch in the UK is £10 approx. This invention using a stick-on substrate would cost less than £ I. This invention has evolved through twenty plus years of research. Whilst examining anti fouling coatings for boats and ships it was found that sea life was unable to grow on this copper/copper alloy surface. The impact on large ships using this coating would have considerable financial rewards. The benefits of not having to bring commercial shipping out of service and into dry docks are obvious. It was also discovered that the invention in salt water did not diminish more than three microns per year for the CuproNickel.
In November 2014 the invention was placed in an outdoor swimming pool comprising of 50,000 litres It was seeded with various named bacteria. The water was passed through a cylinder containing the invention. The first reading of a sample of the water after 4 hours was determined clear of harmful pathogens (below level of detection).
Sheffield Hallam University, Bio Medical Research Centre did tests using MRSA and various other pathogens on (the invention) surfaces of several named substrates. Again the subsequent readings declared no harmful pathogens existed on the surfaces. ( below level of detection).
The success of the invention on solid substrates and its comparable low cost opens up the opportunity to enhance the health of people worldwide, whether in the workplace, home or social environments.
We disclose a method and production process to create at least one flexible copper alloy by placing powder particles of antimicrobial copper on a natural or artificial substrate comprising a substrate having a surface (12) where said particles are bound with a binder, composed of polymeric or a polyepoxide; This process can ba apllied on the two sides of the surface if needed. That is preferrebale in cases like in pipes for watercleaning and aircleaning, where an area of substrate is rolled in a spiral way.
We disclose the use of a Binder, that has the properties to adhere and hold said powder particles of antimicrobial copper on it's surface. This way said particles will be glued on the substrate carrier (12) by the binder (11) in one instance and to the binder in another instance. (see reference Fig 1) We use particle Powder of a copper alloy, of which the particles have a 70 diameter between 30 and 300 microns. The powder can contain a mixture of different diameters.
We may use artificial substrate (12) available on the market on which the binder (11) can be put, and subsequently roll or spray said powder (10).
The powder we use meets the protocol of the EPA (The Environmental Protection Agency of America) of antimicrobial copper. It is currently on the copper market.
We disclose a face mask, that has at least one layer of flexible copper alloy, produced after the method described in Claim 1. Where preferabily said binder is applied by spraying means or rolling means on a textile fabric (e.g. nylon, polyester net) after which said powder is sprayed by spraying means over the active wet surface of the binder. Face masks can have several coated netsworks layers that have a different orientation (e.g. the second net in an alternative position).
We disclose a substrate, that can be composed of the binder, itself; When said binder is hardening depending of the composition a substrate layer is formed, which will preferably will be glueable by the side that is not treated with said powder.Thus a self-glueing surface is composed. This offers the opportunity to the customer of applying this copper alloy sticker to a surface of his choice.
We disclose that the copper alloy surface can be a 2D structure but also a 95 3D structure that is composed of at least two surfaces, to be used in a housing. 3D structures can be added by rolling means, like by standard hand painting rolls.
A 2D or 3D structure that is composed of at least one surface, that is bent or rolled, to be used in a housing; This is a preferable approach to be used in water purification, the water passing through a number of flexible layers of the copper alloys. The space between the layers is controllable eg. by using the rolling method of the surface you will make spaces of higher and lower areas so that the maximum water volume makes contact with the copper alloys coating.
Such structures, as described in Claim 7 and 8, Can be useful for inside of footware, also accessories eg.. gloves, hats and clothing. This invention can be applied by various methods to textiles in the clothing industry; eg one method can be to immerse the product in a bath of binder and then spray the product with said particles. Equally this method of application can be used on various footware products. Another application can he used on the lining of garments.
Such structures, as described in Claim 7 and 8, can be rolled inside various type of domestic or industrial pipes. another additional method is to spray the interior surface of the tubing with the binder and said particles.
These structures, as described in Claim 7 and 8, for the inside of washing machines. The product can be applied to the surface of the drum both inside and out. This would be suitable for low temperature washing machines. This can also be used for coating the interior surface of hand wash buckets and other relevant housing; also the surfaces in laundries/ processing. It is worth mentioning that a by product of cold wash is considerable energy saving.
Structures, like described in Claim 7 and 8, can be used inside waterfiltering systems and installations; Apart from water purification for safe drinking purposes the product can also be used for killing the Pathogens in the water in swimming pool s....a natural water purification method as an alternative to the use of chlorine. The application used is that already described in Claim 10.
We disclose that Structures, as described in Claim 7, 8 and 12, to be used in swimming pools and wellness baths, where the two-step process of binder plus particles can be applied to coat the walls and floors of the swimming pool or the bath (or Jacuzzi), and on a second step the said water filtering structure as described in claim 12; This shows how the invention is advantageous on several complementary levels of copper microbial use; We disclose also that structure, as described in Claim 12 can be used 145 inside airfilter systems and installations; as in domestic air conditioning units; units in automobiles and aeroplanes and workplace offices etc. For clarity we add that, surfaces such as described in claim 1, claim 7, 150 claim 8, being self adhesive surfaces or incorporated surfaces, manufactured for various use as part of products or applications, such as give in next list, but not limited to: a. all kind of supporting means, such as: tables, kitchen worktops, medical operation tables, field hospitals, fields restaurant, etc b. Touch contact zones of various type of electronic devices (such as sleeves, contact disinfection mesh, touchscreens); c. Electrical switches and buttons and plugs: d. Various Grips (subway, stairways, elevators, rolling stairs, ...); e Inhouse door and cardoor parts; f. Banksafes, safe deposit boxes; g. Toilet parts and sanitary means; h. Various workers tools; i. Rollators and trolleys; j. Food processing industry system like bowls and containers; k. Cosmetic bags and other hold all items 1. Steering wheels of vehicles the like of bicycles, motorbike, safety helmets; Artificial leather and leather for the manufacturing of shoes and other footwear, clothings; m. Buckets, Jerrycans and watertanks; n. Phone accessories ie; protective surfaces and sleeves o. Brewing, drinking production installation; p. Trays; q.
