Abstract

The invention discloses a preparation method of a biomass fiber board based on a spherical polymer, and relates to the technical field of biomass fiber board processing. The specific preparation method is as follows: firstly, the polymer is made into a quasi-spherical structure, and then reduced on the surface of the quasi-spherical polymer Generate nano-silver, disperse the formed composite polymer in the emulsion, and impregnate it into the biomass fiber by vacuum pressure impregnation, and then form the fiberboard by hot pressing. In the fiberboard preparation method of the present invention, by treating the biomass fibers, the hot-pressing time and hot-pressing pressure in the hot-pressing process are reduced, thereby achieving the purpose of improving the production efficiency of the fiberboard and reducing energy consumption, and the obtained fiberboard performance data It is relatively excellent and meets the processing requirements in the current market.

Description

technical field [0001] The invention belongs to the technical field of biomass fiber board processing, and in particular relates to a preparation method of a biomass fiber board based on spherical polymers. Background technique [0002] my country is the largest producer of fiberboards in the world. Fiberboards are widely used in furniture, floor substrates and other fields due to their uniform and delicate material, excellent mechanical processing and finishing performance. Fiberboard is a man-made sheet made of wood fiber or other plant fiber and applying urea-formaldehyde resin or other suitable adhesives. Now as a new type of environmentally friendly materials, it is widely used in high-end shoe materials, automotive interiors, high-end packaging and other fields. Adhesives and / or additives may be applied during the manufacturing process. Fiberboard has the advantages of uniform material, small vertical and horizontal strength difference, not easy to crack, etc., and i...
