Embodiment 1
[0022] (1) Fully mix the mixed hard monomer accounting for 20% of the total mass fraction of styrene and methyl methacrylate mixed monomer with methylol acrylamide and acrylic acid.
[0023] (2) Add sodium lauryl sulfate + alkylphenol polyoxyethylene ether aqueous solution accounting for 20% of the total mass fraction in the reaction kettle equipped with stirring device, condensation device, nitrogen protection device and feeding device, pH regulator AMP -96, deionized water, stir evenly, pour the mixed monomer (1) into the reaction kettle, add the initial initiator ammonium persulfate (10wt%), raise the temperature to 80°C, stir, and react until the blue luster lotion.
[0024] (3) At the same time, drop the remaining styrene + methyl methacrylate and butyl acrylate, post-initiator (H 2 o 2 +FeSO 4 ) and the remaining surfactant aqueous solution, anionic water-based polyurethane elastic emulsion.
[0025] Among them, styrene + methyl methacrylate is added to butyl acrylat...
Embodiment 2
[0031] A kind of water-based elastic paint is prepared by the following method:
[0032] (1) Fully mix the mixed hard monomer accounting for 20% of the total mass fraction of styrene and acrylamide mixed monomer with methylol acrylamide and acrylic acid.
[0033] (2) Add sodium dodecylbenzenesulfonate + alkylphenol polyoxyethylene ether aqueous solution accounting for 20% of the total mass fraction in the reaction kettle equipped with stirring device, condensing device, nitrogen protection device and feeding device, and adjust the pH Agent AMP-96, deionized water, stir evenly, pour the mixed monomer (1) into the reaction kettle, add the initial initiator potassium persulfate (10wt%), raise the temperature to 80°C, stir, and react until a bluish Glossy lotion.
[0034] (3) At the same time drop the remaining styrene + acrylamide and ethyl acrylate, post-initiator (H 2 o 2 +FeSO 4 ) and the remaining surfactant aqueous solution, anionic water-based polyurethane elastic emuls...
Embodiment 3
[0039] A kind of water-based elastic paint is prepared by the following method:
[0040] (1) Fully mix the mixed hard monomer accounting for 20% of the total mass fraction of styrene and acrylonitrile mixed monomer with methylol acrylamide and acrylic acid.
[0041] (2) Add 20% of the total mass fraction of sodium lauryl sulfate + sodium dodecyl phenyl ether disulfonate + Sodium laurate aqueous solution, pH regulator AMP-96, deionized water, stir well, pour the mixed monomer (1) into the reaction kettle, add initial initiator potassium persulfate (10wt%), heat up to 80°C, stir , react until a bluish lustrous emulsion is obtained.
[0042] (3) At the same time, drop the remaining styrene + acrylonitrile and isooctyl acrylate, post-initiator (H 2 o 2 +FeSO 4 ) and the remaining surfactant aqueous solution, anionic water-based polyurethane elastic emulsion. Among them, styrene + acrylonitrile is added to isooctyl acrylate at a certain rate R1, and mixed evenly with isooctyl ...
