[0015] specific implementation
[0016] The present invention will be described in detail below through specific examples.
[0017] A straw-added fire-resistant high-density fiberboard is prepared from the following raw materials in parts by weight (kg): crop straw 42, an appropriate amount of sodium hydroxide with a concentration of 2%, an appropriate amount of water, a silane coupling agent kh4501.5, a concentration of 95% ethanol 66, wood scraps 30, aluminum hydroxide 4, zinc borate 2, water-based polyurethane adhesive 7, emulsified paraffin 1.5, pure acrylic emulsion 1;
[0018] The straw-added fire-proof high-density fiberboard according to the present invention is made by the following specific steps:
[0019] (1) After cleaning the crop straw, put it in an oven and bake it to a moisture content of 20%-30%. After cooling, cut it into small pieces of 3-4 cm, and then add 3 times the amount of hydrogen peroxide with a concentration of 2%. Sodium, stirred at a speed of 60...
