Embodiment 1
[0056] Step 1. Prepare the pre-emulsified mixture
[0057]Add 400kg of soft water, 2kg of nonionic emulsifier, 1.5kg of fluorocarbon nonionic emulsifier, 20kg of vinyltrimethoxysiloxane containing unsaturated double bonds, 10kg of acrylic acid, and 100kg of butyl acrylate into a 1000L pre-emulsification kettle. 100kg of methyl methacrylate and 260kg of dodecafluoroacrylate monomer were emulsified for half an hour to obtain a pre-emulsified mixture.
[0058] Step 2. Preparation of Nano-modified Fluorocarbon Emulsion
[0059] Take 1 / 5 of the pre-emulsified mixture prepared in step 1 and add it to a 1000L reactor to heat up to 65°C, add 86.5kg of initiator potassium sulfate and water mixture (including 1kg of potassium sulfate), and heat up to 88°C for 0.5 hours Then add the remaining 4 / 5 pre-emulsified mixture dropwise, the dropwise addition is completed in 2.5 hours, keep the reaction temperature at 92°C, add 20kg of surface-activated inorganic nanomaterial aluminum oxide drop...
