[Abstract] A high-strength straw board includes a straw substrate, on which a sound-absorbing layer, a waterproof layer, and a fireproof layer are sequentially bonded to each of the six sides by an adhesive. The straw substrate is made of wheat straw. The adhesive is a thermoplastic adhesive. The sound-absorbing layer is made of a foam material board prepared from PU matrix resin and hollow polymer microspheres. The waterproof layer is a high-performance fiberboard. The fireproof layer is a magnesium oxide board. The main steps of the production method of the high-strength straw board are: Step 1, preparation of the straw substrate: 1. Material preparation and conveying; 2. Stamping and forming; 3. Hot pressing and paper covering; 4. Cooling, cutting, and sealing; Step 2, preparation of the straw board. This invention has many advantages such as high strength, good sound insulation, good fire resistance, good waterproof performance, and insect and antibacterial properties. It can effectively replace many building materials currently on the market and can be widely used in the production of exterior walls, interior walls, partitions, roofs, doors, mobile homes, and quick-assembly houses.
[Claim 1] A high-strength straw board, comprising a straw substrate, characterized in that: a sound-absorbing layer, a waterproof layer, and a fireproof layer are sequentially bonded to each of the six sides of the straw substrate using an adhesive; the straw substrate is made of crop straw; the adhesive is a thermoplastic adhesive; the sound-absorbing layer is made of a foam material board prepared from PU matrix resin and hollow polymer microspheres; the waterproof layer is a high-performance fiberboard; and the fireproof layer is a magnesium oxide board.
