Análisis de las características mecánicas de un material compuesto a partir de matriz elastomérica de látex reforzado con gránulo de caucho reciclado para elaboración de pisos

Abstract

This investigation work is about analyzing the mechanic characteristics of different configurations of a compound material of elastomeric matrix of reinforced latex with granule of recycled rubber, with the purpose of obtaining a material with optimum mechanic characteristics to elaborate floors. It was generated different configurations of compound material, varying the size of the reinforcement and the volumetric composition of matrix and reinforcement. It was elaborated the standard samples, mixing the material according to the configurations and placing it in aluminum molds which help up to the vulcanization process of the samples. It was conducted the required tests for the mechanic characterization, which are: traction (NTE INEN 1165), compression (NTE INEN 889) and hardness (NTE INEN 887). The results because of the tests are tabulated, averaged, charted and compared. With the corresponding analysis it was determined that the material with the optimum mechanic characteristics for the elaboration of floors is the A3 type which owns a granule size of 0-0,841mm o Tamiz #20 and a volumetric composition of 60% matrix (latex) and 40% reinforcement (recycled granule of rubber). To this material will carry out a test of flammability (ASTM D635 -14) to know its characteristics in case of fire.
