Title in Portuguese
Estudo da adição de lama de bauxita em polímero de poli(metacrilato de metila) por meio de polimerização em massa e moldagem em casting
Keywords in Portuguese
Compósito
lama de bauxita
poli (metacrilato de metila)
Abstract in Portuguese
O trabalho refere-se ao desenvolvimento de formulações de poli (metacrilato de metila) (PMMA) contendo lama de bauxita proveniente de processo Bayer. A adesão entre a lama de bauxita e o poli (metacrilato de metila) ocorreu em todas as concentrações testadas (10-70%), mostrando o aumento progressivo das propriedades mecânicas de resistência à tração, resistência à flexão e módulo de elasticidade na tração como na flexão. As propriedades mecânicas são compatíveis com as diversas finalidades de emprego de superfícies sólidas. A estabilidade térmica do composto de poli (metacrilato de metila) com alto nível de lama de bauxita (70%) é semelhante a do material padrão estudado. Os estudos de citoxidade revelam que superfícies sólidas obtidas a partir de lama vermelha não possuem toxidade nas condições testadas.

Abstract in English
The work refers to the development of formulations of poly (methyl metacrylate) (PMMA) and red mud from Bayer process. The adhesion between PMMA and the filler was achieved in the experimental concentration range (10-70%), showing progressive increase of mechanical properties as flexion resistance and modulus. Other mechanical properties are compatible with service life of solid surfaces. The results of thermal stability indicated that formulation with red mud high content (70%) are similar to the standart. Citotoxicity tests revealed no toxicity of the materials in the test conditions.
