Embodiment Construction
[0017] Implementation 1. Production of fiberglass anchor rods with a size of Φ22mm×1500mm.
[0018] Mix unsaturated polyester resin, nano mullite, aluminum hydroxide, polyurethane, zinc stearate, white carbon black, methyl ethyl ketone peroxide, TBPB, and release agent components in the resin glue tank according to the mass ratio, Stir for 15 minutes to form a uniform resin glue; the mass ratio of each component in the resin glue is: 192 unsaturated polyester resin 82.5%, nano mullite 2%, aluminum hydroxide 3.5%, polyurethane 1.5% %, zinc stearate 4%, white carbon black 2%, methyl ethyl ketone peroxide 1%, TBPB 1.5%, release agent 2%; according to the size of the resin glue tank of the production line, in order to ensure that the glass fiber is fully impregnated , configure at least 5KG of resin glue. Put the evenly stirred resin glue into a vacuum drying oven and evacuate to below -0.1Mpa, and continue vacuuming for 30 minutes to eliminate the air bubbles in the resin glue; ...
