Abstract

Revela-se um processo inovador de fabricação de produtos para indústria da construção civil à base de compósitos de fibrocimento utilizando fibras inorgânicas em conjunto ou separadamente, com fibras poliméricas, naturais ou sintéticas. A presente invenção oferece um processo original de tratamento termo-químico de fibras inorgânicas de base vítrea, derivadas da escória de indústrias siderúrgicas e similares, tratadas e estabilizadas quimicamente com agentes organosilanos, aditivos e catalisadores, para fabricação de compósitos fibrocimento em uma matriz de cimento do tipo portland, podendo ser descrito basicamente das seguintes etapas: a) Preparação de uma mistura com fibras de origem escória siderúrgica predominantemente vitrea em um meio líquido alcoólico-aquoso, formando uma suspensão sob agitação para obtenção de uma polpa; b) Tratamento termoquímico sob agitação com agentes desengraxantes e ativadores de superfície hidrofílica; c) Tratamento termoquímico com reagentes hidrofugantes à base de organosilanos, oxidantes, dispersantes, reticuladores na faixa de emperatura de 20-50 <198>C; d) Reticulação e secagem das fibras à temperatura na faixa de 80 a 150<198>, por um período de 1 a 4 horas; e) Adição dos materiais cimenticios, agregados, adições e aditivos (areia, pó calcário, metacaulim, microsílica, pó de quartzo) formando uma pasta; f) Entrada no processo Hatscheck em uma esteira de manta porosa com sistema de tração por cilindros; g) Secagem do material por sucção a vácuo, conformação e corte da chapa na forma final do produto. A presente invenção refere-se a um método totalmente original de utilização de fibras de escória derivadas das indústrias siderúrgicas e similares que são quimicamente alteradas para incrementar sua resistência alcalina de matrizes cimenticias do tipo Portland com adições. Estas fibras foram utilizadas na fabricação de compósitos de fibrocimento como telhas onduladas, telhas planas, painéis, chapas e produtos derivados para diferentes aplicações nas indústrias da construção civil e arquitetura.
