STRAW DERIVED FIBER BOARD WITH MIDDLE DENSITY AND COMPOSITE FIBER BOARD AND PROCESS FOR PRODUCING THE SAME

摘要

The present invention relates to a kind of composite denseness fiberboard and its manufacturing methods, and wherein the density of fiberboard and other materials is formed by fibrous material, and the fibrous material derives from the paddy or aneurysmal straw of dipping or lamination,;Fiberboard of the invention is the thick yellow pulp 90-97 weight based on dry weight. Adhesive 3-10% by weight; Magma 20-80% wood pulps or fragment 10-77 weight % by weight, adhesive 3-10% by weight by weight; Magma 50-95% cement by weight and water 5-50% by weight; Or 5-30% is formed by vat 70-95% synthetic resin by weight and by weight. t;Waste straw can be recycled, it can be realized the maximization that waste material utilizes simultaneously, it is regarded as natural, therefore environment-friendly materials, it cuts and allows using the nail with binder, and there is excellent bending strength and tensile strength etc., either with or without generation fire, toxic gas, natural material, mainly there is humidity conditioning function by the fiber that rice-straw fibre forms, it will not move, and it is easy to require fire resisting and cold tolerance, intensity or the scheduled function enhancing of surface flatness, such as, its advantages are that the wood consumption that traditional hardboard or particieboard use can be reduced by r.
