Abstract
Products are made from antibacterial resin (plastic) materials using common salt as the main antibacterial agent. The salt may be added during production of the resin, e.g. in the formation of a polyurethane, or added during processing of the resin, e.g. by being fed together with the resin into an extruder or moulding apparatus. Potential products include tubes, pipes, films, cups, baths, textiles and toothbrushes and products for recreational, medical, industrial and construction purposes.
Description
2353283 Antibacterial Resin (Plastic) Materials/Products (With Common
Salt, NaCl, as the antibacterial agent) This invention relates to resin (plastic), both low density and high- density resin (plastic) products, being made with the infusion and/or treatment with sodium chloride (NaCI), also known as common salt, serving as an antibacterial agent, either before or during the manufacture of the resin (plastic) product.
Resin (plastic) products have become virtually part of our everyday living, used all age groups and races for various purposes, from toys to food containers, from CDs to disposable materials and so on. Usually, resin (plastic) materials are not always reactive with many of the things they are used for, neither do they help prevent contents (or materials they are used with) from reactions. Their non-reactive ability is, however, an advantage. On the other hand, it does pose a problem - the unchecked growth of bacteria. A good example of this is the invisible build up of bacteria on kitchen utensils such as the chop board.
This current invention provides a way of minimising the effective growth of bacteria on the point of contact with the contents (or materials they are used with). Common salt is a natural product which, in minute quantifies, is consumed by most people. The inffision and/or treatment with common salt in resin (plastic) firrnly prevents bacteria growth very well without posing any danger to human beings in any form, since like any resin (plastic) product, they are not meant for ingestion. Where products that are used for ingestive purposes (toothbrushes, cutlery medical tubes and pipes) are concerned, a measured amount of not more than 10-25 percent is advised, depending on the purpose. This is because there is a degree of interaction between the surface of the infused/treated resin (plastic) and the content or material for which it is used, as the common salt remains active as an antibacterial on such surfaces.
The process of resin (plastic) infusion and/or treatment with the common salt is in two difFerent ways, depending upon which process the manufacturer chooses to adopt. The three (gaseous, liquid, solid) forms of cornmon salt have been found to be quite possible for this infusion and/or P- treatment process. The only consideration has to be that of economic advantage. Resin, like most C, other organic materials, could be difficult to MIX with water-based materials such as salt, but it is possible. Blendingy the resin (plastic) raw material with common salt in the powdery form is the easiest and most economic, in that the energy consumption is low. Finely pre-nixed compounds make excellent raw materials. These would therefore result as masterbatches, that is, in granular forms.
1. Compounding with common salt when the resin (plastic) is at raw material level. This raw material level could be at the liquid, granule or flake point before they are converted into the usual pefiet form.
2. Another possibility is in manufacturing process of the resin (plastic) raw material is being I formed. Such as in the formation of polyurethane in which the additive (common salt) could be added through an inlet into the in-line mixer where the polyol and the isocyanate mix.
3. At the point of production of resin (plastic) product. A good example of this is in the moulding process. A measured amount of common salt could be constantly fed with resin raw mateiial pellets in the Hooper, which would be thoroughly nixed in the extruder cylinder (or sprue) before it is extruded, ejected, compressed, etc into the desired resin (plastic) product.
In whichever process a manufacturer chooses to adopt, the common salt should be of the finest powdered type, for nixing to be thorough and the total flow of the melt not to be affected. If this is not adhered to, apart fi7om a retarded melt flow, the added salt might become more of an impurity thereby affecting cohesion of the finished product. It could also result in bubbles in postproduction. The other associated problen-4 which could also result, is unsightly and/or coarse texture of the final product.
CLAMS 1. The process of resin (plastic) infusion and/or treatment with common salt, NaCl, before and/or during the manufacture of resin (plastic) raw materials in other to create an antibacterial resin (plastic) product.
2. The process of resin (plastic) liquid, granules or flakes infusion and/or treatment with common salt, NaCl, through compounding during the manufacture of resin (plastic) raw materials in other to create an antibacterial resin (plastic) product.
3. The process of pellets of resin (plastic) being infused and/or treated with common salt, NaCl, through compounding to create a masterbatch with the aim producing resin (plastic) raw materials in other to create an antibacterial resin (plastic) product.
4. The process resin (plastic) infusion and/or treatment with common salt through weighing and feeding into resin (plastic) processing machines together with resin (plastic) raw materials in other to create an antibacterial resin (plastic) product.
S. As in claim 1, claim 2, claim 3, claim 4, above through processes of extrusion, calendering, laminating, injection moulding, compression moulding, blow moulding, rotational moulding, casting thermoforming, and such like processes involved in the manufacture of resin (plastic) products in other to create an antibacterial resin (plastic) product.
6. The process of common salt, NaCL being used as part of an infusion and/or treatment of resin (plastic) raw materials in other to create an antibacterial resin (plastic) product.
7. As in claim 1, claim 2, claim 3, claim 4, and claim 5 above for the use of common salt, NaCl, in measured or unmeasured quantity, being part of an infusion into resin (plastic) raw materials in other to create an antibacterial resin (plastic) product.
