Fluoroalkyl-modified composite organosilicon water-proofing agent and preparing method and application thereof
The invention belongs to the field of water-proofing agents and discloses a fluoroalkyl-modified composite organosilicon water-proofing agent and a preparing method and application thereof. The fluoroalkyl-modified composite organosilicon water-proofing agent is prepared from, by mass, 10-15% of short-carbon-chain alkyl siloxane, 10-15% of long-carbon-chain alkyl siloxane, 40-45% of fluoroalkyl siloxane, 2-3% of complex emulsifier, 2-5% of polyvinyl alcohol, 1-5% of silane coupling agent, 1-3% of aluminum sulfate and the balance water. Short-carbon-chain alkyl siloxane, long-carbon-chain alkyl siloxane and fluoroalkyl siloxane are adopted for being used together to form a composite system, and it is ensured that the water-proofing agent has a good waterproof property and has excellent permeability and weather resistance; the water-proofing agent is W/O/W type pasty, and capable of being widely applied to the waterproof fields of concrete, bricks, mortar and the like, and the antifouling fields of glass and the like, and stability of the water-proofing agent is effectively achieved.
