La presente invención se relaciona con procesos para el reciclaje total de residuos sólidos urbanos y desechos electrónicos domésticos y su utilización como material de construcción en diferentes aplicaciones tanto urbanas como rurales. The present invention relates to processes for the total recycling of urban solid waste and domestic electronic waste and its use as a construction material in different urban and rural applications.
Estado de la Técnica State of the Art
En el campo del reciclaje de residuos sólidos urbanos y desechos electrónicos domésticos, existen múltiples tecnologías para su aprovechamiento, ya sea en la fabricación de productos terminados como envases, textiles o en la fabricación de productos similares a los reciclados, como es el caso de los metales. In the field of recycling of solid urban waste and domestic electronic waste, there are multiple technologies for its use, either in the manufacture of finished products such as packaging, textiles or in the manufacture of products similar to those recycled, such as metals
Entre los documentos del estado del arte encontramos la Patente de Estados unidos No. US3847634A la cual describe un material de construcción liviano y sintético que puede ser usado en bloques de construcción o como piedra decorativa. Se prepara con los subproductos de yeso de la producción de ácido fosfórico o fluorhídrico que contienen trazas de impurezas con cal y silicato soluble con suficiente agua para formar un lodo que puede ser moldeado y al secarse permite desarrollar estructuras similares a las del concreto. El lodo contiene una mezcla por peso de sólidos de 2 a 10% de cal y de 1 a 25% de sílica (Si02). El porcentaje restante es sulfato de calcio proveniente del subproducto de yeso. En este caso los materiales reaccionan para formar silicatos de calcio complejos los cuales actúan para endurecer el material. La resistencia a la compresión de los productos obtenidos está entre 3000-5000 psi. Among the documents of the state of the art we find United States Patent No. US3847634A which describes a lightweight and synthetic building material that can be used in building blocks or as decorative stone. It is prepared with the gypsum byproducts of the production of phosphoric or hydrofluoric acid containing traces of impurities with lime and soluble silicate with enough water to form a sludge that can be molded and when dried allows to develop structures similar to those of concrete. The sludge contains a mixture by weight of solids of 2 to 10% lime and 1 to 25% silica (Si02). The remaining percentage is calcium sulfate from the gypsum byproduct. In this case the materials react to form complex calcium silicates which act to harden the material. The compressive strength of the products obtained is between 3000-5000 psi.
Así mismo tenemos la patente de Estados Unidos No. US4540439A el cual enseña unos ladrillos compuestos de alfa-CaS04 1/2H20 (ACSH), subproducto no purificado, secado o calcinado, proveniente de la manufactura de H3P04. El ACSH se mezcla con 0,5 - 20% de Ca(OH)2 o CaO para ser moldeado en ladrillos inmediatamente o después de un tiempo de almacenamiento máximo de 8 horas. Los ladrillos son moldeados usando una planta convencional de manufactura de piedra sintética y tienen un tiempo mínimo de fraguado antes de uso de 4 horas. Se pueden adicionar materiales desinfectantes, repelentes, rellenos orgánicos ó inorgánicos antes de realizar el moldeo de los ladrillos. Los ladrillos obtenidos tienen una densidad de 1,8 kg/ dm3 y una resistencia a la compresión de 200 kp/ centímetro cuadrado para un ladrillo de 240 x 115 x 71 mm. We also have US Patent No. US4540439A which teaches bricks composed of alpha-CaS0 4 1 / 2H 2 0 (ACSH), unpurified by-product, dried or calcined, from the manufacture of H 3 P0 4 . The ACSH is mixed with 0.5-20% Ca (OH) 2 or CaO to be molded into bricks immediately or after a maximum storage time of 8 hours. The bricks are molded using a conventional synthetic stone manufacturing plant and have a minimum setting time before use of 4 hours. Disinfectants, repellents, organic or inorganic fillers can be added before molding the bricks. The bricks obtained have a density of 1.8 kg / dm3 and a compressive strength of 200 kp / square centimeter for a brick of 240 x 115 x 71 mm.
Aún así, los procesos del estado del arte presentan inconvenientes relacionados con el tiempo de curado y las propiedades mecánicas de los materiales obtenidos. Por lo tanto persiste la necesidad de desarrollar nuevos productos que tengan un tiempo de curado más corto, mejores propiedades mecánicas y un mayor rango de aplicaciones. Even so, the processes of the state of the art have drawbacks related to the curing time and the mechanical properties of the materials obtained. Therefore the need persists to develop new products that have a shorter curing time, better mechanical properties and a greater range of applications.

Descripción detallada de la invención El proceso de la presente solicitud consiste en un método para encapsular residuos sólidos urbanos y desechos electrónicos domésticos no biodegradables, con el fin de obtener un producto que puede ser empleado en la construcción de diferentes obras civiles, particularmente viviendas. El proceso consiste de 3 etapas, a saber: Detailed description of the invention The process of the present application consists of a method to encapsulate urban solid waste and non-biodegradable domestic electronic waste, in order to obtain a product that can be used in the construction of different civil works, particularly housing. The process consists of 3 stages, namely:
Una primera etapa que consiste en el recibo de los residuos sólidos urbanos y desechos electrónicos domésticos, seguida de una clasificación, separación, selección de materiales y reclasificación de acuerdo con un protocolo especifico separando materiales tales como vidrio, papel, cartón, plástico de alta y baja densidad, escombros, cementos, concretos, llantas, metales, material electrónico, baterías, móviles, celulares, desechos de materiales grises, blancos, etc., una vez se han clasificado los residuos sólidos, se lleva a cabo un proceso de secado en un silo donde se tratan con aire seco deshumidificado una temperatura entre 40°C y 70°C por un tiempo entre 20 minutos y 40 minutos. A first stage consisting of the receipt of urban solid waste and domestic electronic waste, followed by a classification, separation, selection of materials and reclassification according to a specific protocol separating materials such as glass, paper, cardboard, high plastic and low density, debris, cement, concrete, tires, metals, electronic material, batteries, mobiles, cell phones, waste of gray, white materials, etc., once the solid waste has been classified, a drying process is carried out in a silo where a temperature between 40 ° C and 70 ° C is treated with dehumidified dry air for a time between 20 minutes and 40 minutes.
El material seleccionado y secado es luego triturado, reduciendo su tamaño a una distribución de tamaño deseada de acuerdo con el proceso de producción o programa de transformación final. The material selected and dried is then crushed, reducing its size to a desired size distribution according to the production process or final transformation program.
La segunda etapa, se toma este material que ha sido debidamente triturado hasta el tamaño deseado, y se combina con diferentes aditivos, ayudas de proceso, lubricantes, rellenos y demás tales como sulfato de calcio, fosfato de zinc, azufre, sílice, pigmentos metálicos, sulfato de potasio, sulfato, ionomero de vidrio, cloruro de sodio, acido fosfórico, dióxido de titanio, oxido de zinc, caolín, estérate, agar, fosfato, acido acetilsalicilico, bicarbonato de sodio, ionomero de vidrio combinado con metal, amoniaco y aromatizantes y otros de acuerdo con la tabla 1. Así mismo, se agregan entre 1,2 y 2,5 litros de agua por cada kilo de material procesado, dependiendo del tipo de producto que se desea obtener. The second stage, this material is taken that has been properly crushed to the desired size, and is combined with different additives, process aids, lubricants, fillers and others such as calcium sulfate, zinc phosphate, sulfur, silica, metallic pigments , potassium sulfate, sulfate, glass ionomer, sodium chloride, phosphoric acid, titanium dioxide, zinc oxide, kaolin, sterate, agar, phosphate, acetylsalicylic acid, sodium bicarbonate, glass ionomer combined with metal, ammonia and flavorings and others according to table 1. Likewise, between 1.2 and 2.5 liters of water are added per kilo of processed material, depending on the type of product to be obtained.
En una tercera etapa, se lleva a cabo un proceso de curado en frió de los diferentes materiales poliméricos presentes en la composición. Este curado se lleva a cabo a temperatura ambiente y su duración oscila entre 15 y 40 minutos. In a third stage, a cold curing process of the different polymeric materials present in the composition is carried out. This curing is carried out at room temperature and its duration ranges from 15 to 40 minutes.
Finalmente se agrega carboximetilcelulosa como coloide protector y aglutinante, en una cantidad que depende de la aplicación final deseada, y se agregan otros componentes para mejorar las características finales del producto, por ejemplo el uso del acido Glicolico le otorga brillo y elasticidad. Finally, carboxymethyl cellulose is added as a protective colloid and binder, in an amount that depends on the desired final application, and other components are added to improve the final characteristics of the product, for example the use of glycolic acid gives it shine and elasticity.
Sin querer ceñirse a una teoría específica, el solicitante está seguro que los compuestos listados como catalizadores en la tabla a continuación causan un ablandamiento de los polímeros presentes en los desechos, lo que permite que estos encapsulen los demás componentes. Este ablandamiento se lleva a cabo a temperatura ambiente, lo cual permite que el proceso se efectúe en lugares donde no hay un flujo constante de electricidad y reduce los costos del mismo. Por esta misma razón, el proceso puede aplicarse a cualquier tipo de residuo sólido urbano, independiente del tipo de polímeros presentes. Tabla 1, lista de componentes del material compuesto obtenido de acuerdo con el proceso descrito. Without wishing to adhere to a specific theory, the applicant is certain that the compounds listed as catalysts in the table below cause a softening of the polymers present in the waste, which allows them to encapsulate the other components. This softening is carried out at room temperature, which allows the process to be carried out in places where there is no constant flow of electricity and reduces its costs. For this same reason, the process can be applied to any type of urban solid waste, regardless of the type of polymers present. Table 1, list of components of the composite material obtained according to the described process.
