Abstract
En esta investigación se desarrolló un nuevo material aislante térmico con materiales abundantes en la región para ser aplicado a futuro en los techos de las viviendas en zonas de friaje. El objetivo de este estudio fue determinar la influencia de la proporción de mezcla, caolín, diatomita y almidón sobre la optimización de la conductividad térmica, mediante pruebas experimentales, con la finalidad de proponer un material con alta capacidad de aislamiento térmico. La metodología utilizada fue un diseño experimental unifactorial con 10 niveles. Para conformar los materiales se utilizó el método consolidación colaje/almidón (SSCC). Los resultados mostraron que la proporción de mezcla óptima fue de 48% de caolín, 10% de diatomita y 42% de almidón, con una porosidad de 66%, una densidad global de 0.83 g/cm3, una absorción de agua de 80%, una conductividad térmica de 0.1311 W/m·K y una resistencia a la compresión diametral de 1.10 MPa. Se concluye que la proporción de mezcla afecta significativamente (p<0.05) en la conductividad térmica y que el nuevo material obtenido con el procesamiento SSCC tiene un equilibrio entre las propiedades de aislamiento térmico y de resistencia mecánica.
In this research, a new thermal insulating material was developed with materials abundant in the region to be applied in the future in the roofs of houses in cold areas. The objective was to determine the influence of the mixture proportion, kaolin, diatomite and starch on the optimization of thermal conductivity, by means of experimental tests, with the purpose of proposing a material with high thermal insulation capacity. The methodology used was a one-factor experimental design with 10 levels. The consolidation/starch consolidation method (SSCC) was used to form the materials. The results showed that the optimum mixing ratio was 48% kaolin, 10% diatomite and 42% starch, with a porosity of 66%, an overall density of 0.83 g/cm3, a water absorption of 80%, a thermal conductivity of 0.1311 W/m·K and a diametral compressive strength of 1.10 MPa. It is concluded that the mixing ratio affects significantly (p<0.05) on the thermal conductivity and that the new material obtained with SSCC processing has a balance between thermal insulation and mechanical strength properties.
