Análisis del coeficiente de fricción e índice de inflamabilidad de un material compuesto a partir de matriz elastomérica de látex reforzado con gránulo de caucho reciclado

Abstract

The present experimental work aims to analyze the coefficient of friction (static and dynamic) and flammability index of a composite material made from elastomeric latex matrix reinforced with recycled rubber granule. Composite specimens with volumetric composition of 60 percent Synthetic latex and 40 percent Recycled rubber granule (particle size of 0.841 mm) were made, and simple material specimens with 100 percent synthetic latex configuration were also made. In addition, aluminum molds were manufactured with the purpose of facilitating the vulcanization process required by the samples. Friction tests (Use Guide for English XL Variable Incidence Tribometer) and flammability were performed under regulations (ISO 3795). Friction tests were carried out on the two materials on three types of surfaces under dry and wet conditions, the values were taken in the 4 directions (north, south, east, west). As a result, the factor with the highest incidence on the value of static and dynamic friction coefficients is the “Condition”. In the case of the “Material” factor, the coefficients of friction of greater value were for the material with a 100 percent synthetic latex composition. While in the "Surface" factor the wood type obtained higher values compared to the other two. On the other hand, it was determined that the “Orientation” factor has no impact on the measurement of friction coefficients. Finally, material flammability tests were performed, for the composite material the burn rate had a value of 9.23 mm / min. While, for the simple material the burn rate was 7.94 mm / min.
