Embodiment 1
[0024] The wheat straw is cut into short pieces of about 5 cm, and then crushed into needle-shaped shavings by a ring flaker or other machinery. Then, the straw scraps and synthetic fibers such as polyester (or polyethylene, polypropylene) (the amount of synthetic fibers added is 10% of the total amount of materials), are mixed and opened in two stages by a mixing opener, and it is made into Straw scrap / synthetic fiber homogeneous mixture. The mixed material is paved by a hybrid fiber air-laying machine to make a uniformly distributed hybrid fiber slab. The slab is then needled two to three times to make a mixed fiber mat. Spray a composite adhesive mixed with a flame retardant and an anti-corrosion / fungal agent on the mixed fiber mat (the amount of the composite adhesive is 15% of the total amount of the material), and then go through hot pressing (temperature 140 ° C, board surface hot pressing pressure 0.5 MPa) , time 20 minutes) to make the composite adhesive in the mixe...
Embodiment 2
[0026] The mixed straw (in any proportion) of wheat straw and rice straw is cut into short materials of about 5 cm, and then made into shavings by a hammer mill. Sieve the crushed material, remove the fine powder, and combine it with synthetic fibers such as polyester (or polyethylene, polypropylene) (the amount of synthetic fiber added is 15% of the total amount of materials), and carry out two stages of mixing and opening through a mixing and opening machine. Mixing and opening, it is made into a homogeneous straw scrap / synthetic fiber mixture. The mixed material is paved by a hybrid fiber air-laying machine to make a uniformly distributed hybrid fiber slab. The slab is then needled two to three times to make a mixed fiber mat. Spray phenolic resin adhesive on the mixed fiber mat (the amount of adhesive is 10% of the total amount of material), and then through hot pressing (temperature 130 ° C, board surface hot pressing pressure 0.2MPa, time 30 minutes) to make the adhesiv...
