Artigo Development of composite material from tire scrapes and latex for application in thermal insulation(Engenharia Térmica, 2009-12) Nascimento, Rubens Maribondo do; Ford, Elmo Thiago Lins Couras; Mendes, J. U. L.; Pereira, C. M. C.; Marques, A. T.Given the unquestionable need of environmental preservation of discarded industrial residues, the scrape of tires, have been seen as a salutary alternative for addictive in concrete, asphalt production and of other composites materials. In this work, grew a composite the base of scrape of tire as reinforcement and latex as matrix, to be used as insulating thermal in "cold" systems (0o C). Analyzed the acting of the material was what plays the thermal conservation when submitted the flow of heat. Verified the temperature profiles in the internal surfaces and it expresses of the composite as well as the temperature gradient in the same. As consequence, in function of the answers of the system, conclusions were reachedArtigo Reaction to the fire of a composite material the base of scrapes of tires and latex for thermal isolation(2015) Ford, Elmo Thiago Lins Couras; Vale, V. A. C.; Mendes, J. U. L.; Nascimento, Rubens Maribondo doThe great majority of the applications of thermal isolation in the strip of drops and averages temperatures (up to 200ºC), it is made of materials aggressive nature, such an as glass wool, rock wool, polystyrene, EPS among others. Such materials, in spite of the effectiveness in the retention of the flow of heat, possess considerable cost and when discarded they are long years to be to decompose. In that context, trying to adapt the world politics the about of the preservation of the environment, a study began with intention of developing a material composite, with properties of thermal, originating from insulating industrial residues. In this research, the behavior of the composite was analyzed, as submitted the fire. For this, the reaction rehearsals were accomplished to the fire for the composites 2:1; 1:1; 1:2 and for the Latex, based in the "con" experiment in agreement with the norm ASTM - E 1334 - 90. As consequence, in function of the answers of the system was possible to be observed to the acting of each mixture proportion.
