Propuesta de material aislante a base del desperdicio agrícola de la planta de maíz, incorporando bioresina de almidón de maíz

Abstract

Abstract: The need to create sustainable and environmentally friendly insulating materials involves using bioresins as binders made from agricultural waste such as corn starch, developing an insulating material with both thermal and acoustic properties, thus reducing energy consumption and improving the comfort of the buildings. Agricultural residues go through a physical and chemical process where the material is selected and crushed to then apply a treatment based on 5% sodium hydroxide, followed by 20% ethanol, and finally washed with water. Bioresin is produced from corn starch, also known as cornstarch, and is prepared by mixing 41.03% water, along with 29.48% glycerin and starch. The mixture is heated in a water bath for a specific time to achieve the right consistency. Then, this bioresin is combined with the natural fiber that has previously been treated and dried. The mixture is compacted in a mold to shape a test tube with dimensions of 30 cm x 15 cm x 0.2 cm (length, width and thickness)
