Hydrophobic and oleophobic harbor engineering concrete protective agent and preparation method thereof
The invention discloses a hydrophobic and oleophobic harbor engineering concrete protective agent and a preparation method thereof. The method comprises the following steps: firstly, carrying out copolymerization on fluoroacrylates and acrylic ester; respectively preparing by free radical polymerization and reversible addition-fragmentation chain transfer living-polymerization methods; and compounding the copolymer with micromolecular organosilane, fluorinated silane and siloxane. Adjustment of the infiltration capacity in concrete can be achieved by controlling the molecular weight of the copolymer; the obtained copolymer can act in the concrete and on the surface of the concrete; a hydrophobic and oleophobic layer containing a fluorocarbon chain with a certain thickness can be effectively formed; low-molecular weight organosilane, fluorinated silane and siloxane can effectively penetrate and enter the inside of the concrete to form a layer of compact protective layer, and thus secondary protection on the concrete is achieved, and the dual-layer protection system can be relatively effectively used for protecting the concrete.
