Coating film forming matter with rapid surface drying performance and preparation method thereof

[0026] A method for preparing a coating film former with fast surface drying performance, comprising the following steps:

[0027] 1) Add film-forming aids to the reaction flask and raise the temperature to 150-155°C;

[0028] 2) mixing acrylate monomers, crosslinking monomers, amine unsaturated monomers and isocyanate crosslinking agents;

[0029] 3) Add the monomer in step 2) dropwise to the reaction flask and stir for reaction, and keep stirring for 2 hours after the dropwise addition;

[0030] 4) Cool down to 80°C, add aminoalcohol compound;

[0031] 5) Add deionized water dropwise within 1 hour. After the dropwise addition, stir and disperse for 2 hours to obtain a coating film-forming material.

[0032] Example 1: Coalescing agent: S-100 mineral spirits 4g, ethylene glycol butyl ether 4g; Acrylic ester monomer: methyl methacrylate 32.2%; Self-crosslinking monomer: acetoacetoxy ethyl methacrylate Ester 1.8g; amine unsaturated monomer: acrylamide 8g; isocyanate crosslinking agent: toluene diisocyanate 1.5g; alcohol amino compound: dimethylethanolamine 1.4g, the rest is deionized water.

[0033] Embodiment 2: Coalescing aid: S-100 solvent naphtha 4g, propylene glycol butyl ether 4g; Acrylic monomer: methyl methacrylate 33%; Self-crosslinking monomer: acetoacetoxy ethyl methacrylate 1.2 g; amine unsaturated monomer: 6 g of methylol acrylamide; isocyanate crosslinking agent: 1.5 g of toluene diisocyanate; alcohol amino compound: 2.4 g of triethanolamine, and the rest is deionized water.
