| titleOfInvention | Nano SiO2Modified acrylate polyurethane composite waterproof agent emulsion |
| abstract | The invention discloses a nano SiO 2 The composite waterproof emulsion of modified acrylate polyurethane consists of nanometer SiO 12-18 weight portions 2 The coating is prepared by emulsion polymerization of sol, 46-62 parts of aqueous polyurethane prepolymer emulsion, 26-38 parts of acrylate monomer, 7-12 parts of polymerizable organosilicon monomer (shown as formula 1), 6-12 parts of composite emulsifier, 0.4-0.7 part of initiator and 220-280 parts of water; the preparation method comprises the following steps: taking nano SiO with formula amount 2 Putting the sol, the aqueous polyurethane prepolymer emulsion, the acrylate monomer, the emulsifier and a proper amount of water into a reactor, and stirring to form an emulsion; heating to 75 ℃, adding a small amount of initiator aqueous solution, and reacting for 0.5h under heat preservation; dropwise adding the rest initiator aqueous solution within 1h, and then carrying out heat preservation reaction for 2 h; heating to 80 ℃, and keeping the temperature for 0.5 h;cooling and filtering to obtain the nano SiO 2 Modified acrylate polyurethane composite waterproof agent emulsion. |
