Abstract
"ARTIGO MOLDADO FABRICADO COM PAPEL HIDRáULICO". A invenção pode fornecer uma placa fabricada com papel que pode ser um material de construção útil como uma alternativa para a placa convencional que utiliza amianto, especificamente um artigo moldado fabricado com papel hidráulico que é excelente em termos de desempenho reforçado de ambas as resistências à flexão e ao impacto e tem custo reduzido de fibra de reforço. Pela dispersão uniforme em uma matriz de artigo moldado, a fibra sintética orgânica possuindo alta afinidade com cimento (A) e a fibra sintética orgânica possuindo baixa afinidade com cimento (B) como fibra de reforço possuindo uma finura de monofilamento de 0,5 a 10 dtex e um comprimento de fibra de 2 a 20 mm, de forma que o artigo moldado tenha uma resistência à flexão de pelo menos 35% com uso de fibra sintética orgânica (B) apenas, em uma quantidade igual à quantidade total de ambas a fibra (A) e a fibra (B), e apresenta uma resistência ao impacto de pelo menos 10% com uso da fibra sintética orgânica (A) sozinha em uma quantidade igual à quantidade total de ambas as fibras (A) e (B). A razão de mistura por massa da fibra sintética orgânica (A) para a fibra sintética orgânica (B) é preferivelmente de 70/30 a 10/90, e a resistência média da fibra da fibra de reforço geral é preferivelmente de pelo menos 6,5 cN/dtex, e a resistência de fibra da fibra sintética orgânica (A) e a fibra sintética orgânica (B) é preferivelmente de 9 cN/dtex e 4 cN/dtex, respectivamente. O conteúdo total da fibra sintética orgânica (A) e (B) no artigo moldado é preferivelmente de 1 a 10% por massa. O conteúdo de polpa no artigo moldado é preferivelmente de 2 a 6% por massa."MOLDED ARTICLE MANUFACTURED WITH HYDRAULIC PAPER". The invention may provide a paperboard which may be a building material useful as an alternative to conventional asbestos-based board, specifically a molded article made of hydraulic paper which is excellent in terms of the enhanced performance of both flexural strengths. and impact and has reduced cost of reinforcing fiber. By uniform dispersion in a molded article matrix, organic synthetic fiber having high affinity for cement (A) and organic synthetic fiber having low affinity for cement (B) as reinforcing fiber having a monofilament fineness of 0.5 to 10 dtex and a fiber length of 2 to 20 mm, so that the molded article has a flexural strength of at least 35% using organic synthetic fiber (B) only, in an amount equal to the total amount of both fiber. (A) and fiber (B), and have an impact resistance of at least 10% using organic synthetic fiber (A) alone in an amount equal to the total amount of both fibers (A) and (B). The blend ratio by weight of organic synthetic fiber (A) to organic synthetic fiber (B) is preferably from 70/30 to 10/90, and the average fiber strength of the general reinforcement fiber is preferably at least 6, 5 cN / dtex, and the fiber strength of organic synthetic fiber (A) and organic synthetic fiber (B) is preferably 9 cN / dtex and 4 cN / dtex, respectively. The total content of organic synthetic fiber (A) and (B) in the molded article is preferably from 1 to 10% by mass. The pulp content in the molded article is preferably from 2 to 6% by mass.
