[Abstract] The present invention discloses a method for making paper-faced straw board, comprising the following steps: 1. sorting and selecting rice straw raw material; 2. crushing the sorted rice straw and removing dust; 3. uniformly mixing the dust-removed rice straw with multiple groups of mineral binders and then feeding the mixture into a blender; 4. adding plant starch to the blender and continuing to stir the mixture until a straw board slurry is obtained; 5. continuously pouring the straw board slurry between two layers of paperboard in a gluing device coated with environmentally friendly urea-formaldehyde resin glue on a board blank, thereby forming the board through hot stamping; 6. finally, solidifying, cutting, drying, and sawing the straw board to produce the paper-faced straw board. The present invention's method for making paper-faced straw board uses rice straw as the primary raw material, employs a hot stamping process, and employs a glue-coating and paper-laminating heat-curing production process. The product is energy-saving and environmentally friendly, has a moderate density, high static bending strength, is not easily deformed, and has good processing properties, making it an ideal new wall building material.

[Sovereignty Item] A method for making a paper-faced straw board, characterized in that it comprises the following steps: 1. sorting and selecting the straw raw material first; 2. crushing the sorted straw and removing dust; 3. mixing the dust-removed straw and multiple groups of mineral binders evenly and then feeding them into a blender; 4. adding plant starch into the blender and continuing to stir evenly to obtain a straw board slurry; 5. continuously pouring the straw board slurry between two layers of cardboard in a gluing device on which an environmentally friendly urea-formaldehyde resin glue is coated on the board embryo, thereby hot stamping and forming; 6. finally, the straw board is solidified, cut, dried, and sawed to obtain a paper-faced straw board.
