Example Embodiment

[0028] Example 1

[0029] A finish paint, which is composed of two parts A and B; the A part is composed of the following components: hydroxy acrylic monomer (Bayer hydroxy acrylic dispersion 2695) 700g, dispersant (BYK wetting and dispersing agent BYK191) 1.5g, pH adjuster (PH adjuster AMP-95 from Dow Company) 4g, defoamer (BYK024 defoamer BYK024) 0.5g, leveling agent (Nopper thickening and leveling agent 612) 4g; The part B is isocyanate (Bayer isocyanate 2655) 568g, part B is added to part A before use.

Example Embodiment

[0030] Example 2

[0031] A finish paint, which is composed of two parts A and B; the A part is composed of the following components: hydroxy acrylic monomer (Bayer hydroxy acrylic dispersion 2695) 800g, dispersant (BYK wetting and dispersing agent BYK191) 2g, pH adjuster (PH adjuster AMP-95 from Dow Company) 5g, defoamer (BYK024 defoamer BYK024) 1g, leveling agent (Nopper thickening and leveling agent 612) 4.5g ; The part B is isocyanate (Bayer isocyanate 2655), 400g, add part B to part A before use.

Example Embodiment

[0032] Example 3

[0033] A finish paint, which is composed of two parts A and B; the A part is composed of the following components: hydroxy acrylic monomer (Bayer Hydroxy Acrylic Dispersion 2695) 750g, dispersant (BYK wetting and dispersing agent BYK191) 1g, pH adjuster (PH adjuster AMP-95 from Dow Company) 4.5g, defoamer (BYK024 defoamer BYK024) 0.8g, leveling agent (Nopper thickening and leveling agent 612) 5g; The part B is 189 g of isocyanate (Bayer isocyanate 2655), and part B is added to part A before use.

[0034] Taking the finish paint prepared in Example 3 as an example, the stain resistance, acid and alkali resistance, and anti-graffiti performance were compared with the traditional finish paint and the finish paint published by publication number CN102816483A. The results are shown in Table 3.

Abstract

The invention discloses a finish-coat paint. The finish-coat paint is composed of a component A and a component B at a mass ratio of 1.25:4; the component A comprises, by weight, 20 to 30 parts of deionized water, 70 to 80 parts of hydroxyl acrylic monomer, and 0.1 to 0.2 part of a dispersant; the component B is isocyanate. The finish-coat paint is excellent in weatherability; coating film servicelife is prolonged; the finish-coat paint possesses chemical resistance, doodle resistance, is suitable to be used at poor environment conditions, and the using range of the finish-coat paint is enlarged.
