Definitions
- the present invention relates to a process for the preparation of sponges based on polyurethane foam, modified in its toxicity level and in its anti-bacterial characteristics, by means of the addition of a nano-based anti-bacterial compound copper particles
- Solid materials capable of absorbing an amount of water and / or aqueous fluids have long been used in various applications, of such materials in the prior art.
- synthetic sponges were used, in various applications in which the quality of absorption of an important volume of liquid is necessary with respect to its size and weight.
- natural sponges have long been replaced by synthetic sponges.
- the advantages of synthetic sponges are varied, among others, a guaranteed supply, can be made in various sizes and shapes according to their application and a lower cost.
- Said synthetic sponges can be made from a variety of polymeric materials that include; vinyl, viscose, cellulose, rubber, and polyurethane among others.
- a sponge is a tool used, among other applications, for body hygiene or cleaning other surfaces, due to its ability to absorb water or other liquid products.
- the sponge is a porous material that can be made from cellulosic fibers or plastic polymers (usually polyurethane). They exist as previously indicated, natural sponges, used in hygiene work, although they are mainly used for facial or body cleansing.
- the sponges in the bathroom are used to distribute the soap throughout the body during ordinary hygiene activities. They can also be used for washing dishes or utensils, which consist of some cases, of a combination of sponge and scourer so that they can be used interchangeably.
- the present invention is related to polyurethane-based sponges, which was discovered and patented in 1937, by Imperial Patent No. DRP-728,981 of November 13, 1937, in the name of Otto Bayer.
- polyurethane foams are prepared by reacting polyisocyanate with a polyhydroxy compound, in the presence of water, which acts as a bubbling or blowing agent. Water reacts with isocyanate groups, releasing CO2 carbon dioxide, a gas that makes up the trapped cells or bubbles, once the polyurethane has cured.
- the present invention solves the problem previously indicated by the use of "copper nanoparticles" as a bactericidal and fungicidal agent, which presents no risks to humans, thereby simplifying the preparation of the polyurethane foam containing the nano copper particles
- the preparation of the base foam does not have large differences with the modalities used in the prior art
- said foam is prepared from a mixture of a high molecular weight poly-alcohol to which it is added, Toluene Diisocyanate (DIT) and water.
- DIT Toluene Diisocyanate
- the mixing is carried out in the presence of amino, metal and silicone catalysts, in small quantities.
- Certain types of foams are made by adding soluble dyes to the mixture.
- foams require certain physical characteristics, such as high hardness, these are made with variations of the basic Polyol and catalysts, such as special amines or silicones.
- the final product obtained is a stable, flexible, resilient, non-toxic polyurethane foam, suitable for laminating in thickness. thin, capable of being used in mattresses, quilts, footwear industry, upholstery, insulation, shock protection and possible to be cut for the manufacture of sponges of a smaller size, etc.
- the foam is subjected to a treatment with a flame retardant or flame retardant, as the name implies, which makes it difficult to burn and resist, without combusting against possible burns of lighted cigarettes or matches, etc.
- Polyol polyether alcohol of the main reactive long chain, which with its OH radicals binds to the TDI (Toluen diisocyanate) to form the foam.
- Silicone polydimethylsiloxane, non-hydrolysable surfactant, decreases the surface tension of the polyol, improving its reaction capacity; additionally increases the resistance of the cell walls, preventing the foam from collapsing.
- Amine 33% triethylene diamine in polypropylene glycol, acts as a catalyst for the reaction between TDI and water.
- Amine bis (dimethylaminoethyl) ether, 70% in dipropylene glycol, acts as a reaction catalyst.
- Tin Octoate Tin II salt of 2-ethylhexoic acid acts as a catalyst for the reaction between polyol and TDI, a reaction known as foam gelation.
- Dyes Polyol soluble dyes, dye the foam of various colors, without affecting the chemical composition.
- the raw material or components are available, in tanks or tanks, which have their respective pumps and from them, according to a pre-established dosage, these compounds are sent by pipes to the mixing machine.
- the foam in formation passes from the mixer, to an accumulation and distribution pan, then going to the growth and expansion tunnel.
- Said tunnel has the walls and floor, covered with kraft paper and a polyethylene sheet, in addition, the tunnel floor advances at a pre-established dosage rate receiving the compounds of the mixture, then once the mixing of them is finished and formed a block of foam, which has an approximate weight of 270 kilograms, this block is transported in one piece until it ends in a cutter or guillotine.
- the foam Upon reaching the cutter or guillotine, the foam is firm enough to be guillotined in the pre-established sizes required to form the sponges.
- the foam already cut is sent later, to the courts of "curing", by means of cranes cranes specially conditioned, to be subjected to a procedure of "curing" of approximately 24 hours. After this cure, the foam is ready for storage and commercialization.
