Embodiment 1
[0026] A moisture-proof wall construction method, comprising the following steps:
[0027] Add ethylene glycol diacrylate, hydroxyethyl methacrylate, 2,4,6-trimethylbenzoyl-diphenylphosphine oxide, and polyvinyl alcohol into the chemical kettle, stir evenly, and pressurize to 0.2-0.3MPa, hold the pressure for 1.5-2 hours to obtain a composite mother liquor; in which ethylene glycol diacrylate, hydroxyethyl methacrylate, 2,4,6-trimethylbenzoyl-diphenylphosphine oxide The molar ratio with polyvinyl alcohol is 1:2:0.5:2.5, the composite mother liquor and microsilica powder, silane-terminated polyether, alkylsulfonic acid phenyl ester, phenylmaleimide-based silicone resin are put into Stir in an internal mixer at 50-60°C for 20-30min and cool naturally to obtain a wall surface interface agent; The mass ratio of imine-based silicone resin is 35:10:6:2:1, and the interface agent is evenly coated on the wall base to form an interface layer. The thickness of the interface layer reach...
