[Abstract] This invention discloses a method for manufacturing paper-faced straw board, comprising the following steps: 1. Sorting and selecting rice straw raw materials; 2. Crushing and dusting the sorted rice straw; 3. Mixing the dust-removed rice straw with multiple mineral binders and then feeding it into a mixer; 4. Adding plant starch to the mixer and continuing to stir until uniform to obtain straw board slurry; 5. Continuously pouring the straw board slurry into a gluing device coated with environmentally friendly urea-formaldehyde resin onto two layers of cardboard for hot stamping; 6. Finally, the straw board is solidified, cut, dried, and trimmed to obtain the paper-faced straw board. This invention's method for manufacturing paper-faced straw board uses rice straw as the main raw material and employs a hot stamping process, followed by gluing, paper lamination, and thermosetting. The resulting product is energy-saving and environmentally friendly, with moderate density, high static bending strength, and is not easily deformed. It also has good processing performance, making it an ideal new type of wall building material.

[Claim 1] A method for producing paper-faced straw board, characterized by the following steps: 1. Sorting and selecting rice straw raw materials; 2. Crushing and removing dust from the sorted rice straw; 3. Mixing the dust-removed rice straw with multiple groups of mineral binders evenly and then feeding it into a mixer; 4. Adding plant starch to the mixer and continuing to stir evenly to obtain straw board slurry; 5. Continuously pouring the straw board slurry into a gluing device that coats the board blank with environmentally friendly urea-formaldehyde resin between two layers of cardboard for hot stamping; 6. Finally, the straw board is solidified, cut, dried, and trimmed to obtain paper-faced straw board.
