Abstract

The invention discloses a novel straw fiber ridged plate and a manufacturing method thereof. The novel straw fiber ridged plate is prepared from the following components in weight percentage: 46 to 54 percent of crop straw powder, 10 to 13 percent of slag powder, 5 to 10 percent of talcpowder, 25 to 35 percent of magnesium oxide, 0.2 to 0.6 percent of additive (1) and 0.4 to 0.8 percent of additive (2). The manufacturing method comprises the following steps of: smashing the organic fiber materials such as straws and milling the smashed materials into powder; stirring and uniformly mixing the organic fiber powder, the slag powder, the talcpowder and the magnesium oxide; adding the additive (1) and the additive (2) into the mixed material of the organic fiber powder, the slag powder, the talcpowder and the magnesium oxide, adding water into the mixed material and uniformly stirring and blending the obtained mixture; filling the mixture into a die at regulated temperature and pressure, cold pressing the mixture to form a semi-product and removing the die from the semi-product; trimming the semi-product which is separated from the die according to the specification requirements of a product; and filling the semi-product which is trimmed after die removal into a pressure maintaining die for maintenance to obtain a finished product and then storing the finished product in a warehouse.

Description

technical field [0001] The invention relates to a straw fiber board and a manufacturing method thereof, in particular to a novel straw fiber ribbed board and a manufacturing method thereof. It belongs to the technical field of building components and decoration. Background technique [0002] At present, most of the raw materials of synthetic boards manufactured in China are wood materials such as miscellaneous wood, board scraps, sawdust, etc.; because the source of wood raw materials is restricted by environmental protection and other reasons, its supply is not only limited, And the price is high; therefore, some domestic enterprises and research institutions are constantly looking for artificial boards and other available alternative materials. Although some enterprises have made certain attempts to use crop straws to manufacture boards, the boards produced have some defects in terms of strength, flame retardancy, acid and alkali resistance, water resistance, and environm...
