Abstract

"MICROFIBRAS PARA REFORçO DE MATRIZES INORGâNICAS, COMO CIMENTO, ARGAMASSA GESSO E CONCRETO, MICROFIBRAS à BASE DE POLIAMIDA PARA REFORçO DE MATRIZES INORGâNICAS, PROCESSO PARA OBTENçãO DE MICROFIBRAS à BASE DE POLIAMIDA PARA REFORçO DE MATRIZES INORGâNICAS E PRODUTOS à BASE DE FIBROCIMENTO". A presente invenção trata de microfibras utilizadas como reforço de cimento, gesso, argamassa ou concreto, empregáveis em vários tipos de materiais, como os de construção, como por exemplo, pisos, telhas, caixas d'água, tubulações, especialmente para transporte de esgoto, entre outros. Particularmente as microfibras à base de poliamida para reforço de fibrocimento são caracterizadas pelo fato de apresentarem título menor ou igual a 1 dtex, módulo elástico maior que 1 GPa, alongamento na ruptura entre cerca de 8 a 40% e tenacidade podendo variar entre aproximadamente 30 e 100 cN/tex. O alto módulo nestes produtos aumenta a sua tensão após ruptura, resultando em produtos com maior ductilidade. As fibras são fiadas com uma vazão do fundido no capilar reduzida e depois submetidas a altas taxas de estiramento para obter fibras de alto módulo e baixo título podendo ser posteriormente submetidos a tratamento superficial, tal como revestimento com látices acrílicos ou similares para melhorar a adesão entre as fibras e a matriz inorgânica."MICROFIBERS FOR INORGANIC MATRIX REINFORCEMENT AS CEMENT, PLASTER AND CONCRETE MORTAR" The present invention relates to microfibers used for reinforcing cement, plaster, mortar or concrete, employable in various types of materials, such as construction, such as floors, tiles, water tanks, pipes, especially for sewage transportation. , among others. Particularly fiber-reinforced polyamide-based microfibers are characterized by having a titer of less than or equal to 1 dtex, elastic modulus greater than 1 GPa, elongation at break of about 8 to 40% and toughness ranging from approximately 30 to 100 cN / tex. The high modulus in these products increases their stress after breakage, resulting in higher ductility products. The fibers are spun with reduced melt flow into the capillary and then subjected to high draw rates to obtain high modulus and low titer fibers and may be further surface treated, such as coating with acrylic latex or the like to improve adhesion between the fibers. the fibers and the inorganic matrix.
