Embodiment 1
[0039] see figure 1 Prepare waste circuit board resin powder with a mass fraction of 65% in the particle size range of 2 to 5 mm, a mass fraction of 25% polyurethane powder in the particle size range of 1 to 20 mm and a mass percentage of 10% in the particle size range of 1 to 10 mm The sawdust powder is fully mixed in the mixer, and the stearic acid accounting for 5% of the weight of the mixed material is added for blending modification; the modified mixed non-metallic material is fully mixed with the cement powder according to the mass percentage of 80%, and added A proper amount of water is stirred and mixed to form a slurry; the slurry is injected into the test mold and cast into shape; the test mold injected with the slurry is placed on a vibrator to vibrate for 5 minutes to remove air bubbles and accelerate the hydrothermal synthesis reaction of the gelling material; Scrape the surface of the slurry with a scraper; demould after 24 hours, and obtain a composite reinforce...
Embodiment 2
[0041] see figure 1 Prepare waste circuit board resin powder with a mass fraction of 85% in the particle size range of 0.5-2mm, a mass fraction of 10% polyurethane powder in the particle size range of 1-10mm and a mass percentage of 5% in the particle size range of 1-5mm fully mix the straw powder in a mixer, add titanate accounting for 3% of the weight of the mixed material for blending modification; fully mix the modified mixed non-metallic material with cement powder at a mass percentage of 70%, and add an appropriate amount of The water is stirred and mixed to form a slurry; the slurry is injected into the test mold and cast into shape; the test mold injected with the slurry is placed on a vibrator to vibrate for 3 minutes to remove air bubbles and accelerate the hydrothermal synthesis reaction of the gelling material; use a scraper Scrape the surface of the slurry; release the mold after 24 hours, and obtain a composite reinforced profile after drying.
Embodiment 3
[0043] seefigure 1 Prepare waste circuit board resin powder with a mass fraction of 60% in the particle size range of 0.5-2mm, a mass fraction of 30% polyurethane powder in the particle size range of 1-10mm and a mass percentage of 10% in the particle size range of 1-5mm The peanut shell powder is fully mixed in a mixer, and the stearic acid accounting for 1% of the weight of the mixed material is added to carry out blending modification; the modified mixed non-metallic material is fully mixed with cement powder according to 65% by mass, and added A proper amount of water is stirred and mixed to form a slurry; the slurry is injected into the test mold and cast into shape; the test mold injected with the slurry is placed on a vibrator to vibrate for 1 min to remove air bubbles and accelerate the hydrothermal synthesis reaction of the gelling material; Scrape the surface of the slurry with a scraper; demould after 24 hours, and obtain a composite reinforced profile after drying. ...
